The pump is stuck in the well, how to get it out. What to do if the pump falls or gets stuck in the well How to lift the pump from the well

During operation of a source, it often becomes necessary to obtain pump equipment from the casing pipe. However, when carrying out this procedure, they often encounter a problem: the pump gets stuck in the well.

  • deposits in the mine;
  • sagging power cable;
  • siltation of the bottom of the source;
  • reverse siltation;
  • obstacles, debris;
  • deformation of the casing;
  • pump misalignment;
  • caught on pipe joints.
  1. Deposits in the well. The reason is the soil in which the casing is installed. Limestone rocks in interaction with metal body apparatus plus oxygen give a durable stone coating. Deposits can form both on the device itself and on the walls of the pipe where the equipment is located. If, when lifting the device by the cable, there is no movement either up or down, and the cable and cable do not move when tensioned, this is a sure sign that there are salt deposits in the shaft.
  2. Slack cable. The pump is held suspended in the pipe using a cable and a reliable bolted connection. In addition, a hose or pipe and a power cable are connected to the device. Often, when pulling the device by the cable, we forget to pull out the cable in parallel, and after a few meters it sags and wraps around the pump body. This can happen if, when the equipment was first submerged, the power cable was not attached to the rope with special clamps. It sagged during the operation of the well and was wound around the device due to vibration. If, when you try to pull the device by the cable, it goes tight and constantly gets stuck, the reason is the sagging cable.
  3. Silting of the well bottom. After drilling and installation, the casing pump is lowered too deep. Equipment almost always gets stuck in sludge. In the pipe there is a natural process of formation of sludge at the bottom. In the first years of water consumption, the problem of siltation will not be identified, because it comes in clean and soil has not yet accumulated at the bottom. After prolonged use, the water from the device may contain an admixture of liquid clay and change its color. This is a sure sign that he drowned in the mud.
  4. Reverse siltation. In addition to the accumulation of sludge at the bottom of the source, there is the problem of complete blocking of the device body inside the casing pipe with sludge. This happens due to displacement of the seams at the joints, or due to improper installation of the casing pipe. It also occurs in a mine at sandy soil, since sand and eroded soil get into the holes above the pump location along with water. Gradually, the silt covers it completely and envelops it, preventing it from being pulled to the surface. If the cable, when taut, moves little by little, then up and then down, it means that the pump is stuck in silt, and reverse silting has occurred in the well.
  5. There was garbage. There is little space in the water well; pumping equipment barely fits into it; however, during use, debris or foreign objects may get into the well for some reason. It is not always possible to keep track of the pipes. Children throw stones and toys; small animals and birds are found in the pipe (although this rarely happens). Foreign objects make it difficult to remove the pump from the well. Debris that gets into the barrel falls to the very bottom and rests against the pump. A clear sign of a hit foreign object into the shaft there will be a characteristic shuffling and grinding sound when trying to pull the cable.
  6. Deformation of the casing. Incorrect installation and dishonest attitude towards work lead to problems in the wellbore. Deep water-bearing pipes are assembled using a screw connection or a tongue-and-groove method. There is therefore a risk of detachment at the joints. This happens due to the negligence of workers, or due to the characteristics of the soil. The pipes move away from each other and become askew. A shelf is formed in the trunk, and accordingly, the channel narrows. Characteristic sign casing deformation - knocking and sudden stop during lifting.
  7. Pump misalignment. The decision to remove the device from the mine shaft has been made, and it’s time to start pulling it out. But after several movements in the upward direction, it gets stuck and does not move, which means there is a misalignment. The reason is a rope or cable that, during lifting, got caught on the bottom of the equipment or a side connection, as a result of which the equipment became a wedge.
  8. The device got caught on the pipe joints. During the lifting process, it may have hit a butt joint. Determining the cause is quite simple. The average length of a metal pipe is 6-8 meters, polyethylene – 4-6 meters. You need to measure the appropriate length on the cable; when pulling it out, it will become clear what the depth is and which seam the pump rests on.

Several ways to remove the device

Salt and limestone deposits

Pull the cable several times without using maximum force, gradually moving the cable up and down, like a fishing rod. If this does not help, there is another way - to break up the deposits with a pneumatic blow. Quite an expensive method, but with positive characteristics. Will be needed powerful compressor and a long tube with a diameter of 15 mm. It is lowered to the level of the unit and connected to the compressor. Then they shoot a stream of air into the equipment body or along the pipe wall. The shot should break the coating and release the device.

Cable slack

Cables are different. They are selected depending on the power of the unit. Stronger devices require a rigid, reinforced cable. If it sags, it will not wrap around the body, but will simply warp the device, which will make it impossible to lift it to the surface. It will be enough to pull out the cable along with the cable and hose. If the cable does wind up around the pump body, it thickens it. In this case, you need to bring it down and also move it by the cable, like a fishing rod. The cable will gradually unwind and allow the pump to continue moving.

Silting of the bottom

When silt and dirt form at the bottom of the well, the apparatus is pulled out by gradually swinging from side to side by the rope and hose. However, if the depth is large enough, the length of the cable will not allow the device to be swung to the required extent. To remove a stuck unit, you need to dilute the sludge big amount water. Preferably under good pressure. An additional source of water and equipment to supply it to the mine shaft will be required. It is advisable to lower the tube to the very bottom and use a pump to pump water into the well under pressure. Simultaneously with the supply of liquid, the cable must be pulled up, creating tension in the ground lock. After a few minutes the equipment should be free. But don’t rush to pull it up right away. To rinse the sludge a little, the pump must be dipped into water several times without stopping its supply.

Reverse siltation

In this case, the apparatus is completely blocked in the ground, and often a soil cap is formed above it; more water will have to be poured into the well. more water. Simply swinging and pulling out the device will no longer work. Otherwise, the cable will break and it will be more difficult to get it out. To dilute the sludge, you need to lower a tube with a diameter of 15-25 mm into it, and then use another pump to pump water down from the surface, and the more water, the better. Now the stuck unit can be safely pulled out.

Important: to build up pressure in a well, they sometimes use fire truck. This is expensive, so before pulling out the pump in this way, it is necessary to calculate the cost-effectiveness of the procedure compared to the cost of the device.

Garbage got in

A foreign object in the barrel is one of the few reasons not to take any action to remove a stuck device. If, after walking a few meters, the pump stops with a characteristic shuffling or knocking sound, you can try to pull it out along with the object. Of course, the garbage itself is not visible, which means one can only guess what is there. Translational movements up and down can loosen it and move it. If it doesn't work out, you'll have to leave the pump inside.

Casing pipe deformation

IN in this case the diameter of the mine shaft narrows. When moving upward, the device rests on a bulge in the pipe. Any work to remove the pump must be done blindly, but there is an excellent method that is suitable if the column is deformed.

You need to make a special pencil case with your own hands; a mini-video camera is placed in it, pointing down. The camera must be in a waterproof case. A flashlight, also waterproof, is tied to it. The diameter of the pencil case with the camera should be 1.5 times smaller. The pencil case is tied to a rope and lowered into the well. The camera clearly shows the place of narrowing and the possibility of moving the device further.

Skew and snagging on joints in the pipe

This happens quite often. If the pump is stuck in a wedge, it needs to be rocked. We pull the cable with one hand, and the hose or cable with the other, in turn. Moreover, they should not be pulled too hard or sharply, as they may come off. Movements such as swings will loosen the equipment and bring it into the desired vertical position.

The same applies to the case of the pump catching on the joints. Almost similar movements help to swing the pump and release it. You can lower the device half a meter lower and try to raise it again, moving the rope or cable along the walls of the entire circumference of the pipe.

Jamming on the rise

If the device stands across the pipe, and when the cable is loosened, it sags and does not feel tension, you will have to resort to another method.

You will need a long pole or tube with a diameter of 15 - 20 mm. Can be used propylene pipe. It bends and will easily fit into the mine shaft. Having placed the rod inside, you need to try to push the pump down, while loosening the cable and cable so as not to tear them. A small spatula is attached to the end of the rod. Having lowered the device, the device is lifted up, pushing from below.

In sand and limestone wells

In the first case, silting occurs in the pump and the bottom of the pipe. Especially if water is rarely used and the well has stood idle for several months. It is clear that it is difficult to remove the unit from wet sand. But there is a way. In order for water to penetrate between the pump wall and the ground, it must be gradually, not jerkily, pulled up, and then the cable must be loosened for a short time. Then do everything again, this can take a lot of time. It all depends on how thick layer sand has formed around the device. So, a few centimeters at a time, the device is gradually removed from the sandy captivity.

Important: You should not try to wash away the sand with water pressure, this will only lead to compaction.

In the second case, the situation is similar with sand. Lime deposits when interacting with oxygen and metal, forming stone walls. To free the apparatus from reverse siltation, you must not try to pump in water or mechanically break the stone. This may damage the equipment. It must be turned on when swinging. The vibration from the unit will help it release faster.

How to get the unit if the cable breaks

This is a problem in which owners abandon equipment right in the trunk and lower new ones there. Of course, this can be done if the unit fell to the bottom and sank. And the depth of the mine allows water intake to be higher than before.

When the break occurs above the water level, the unit will still have to be removed. You need to make a special device yourself. By analogy with a mixer or a kitchen whisk, we twist a spiral from the fittings with a sharp end slightly larger than the pump itself. We lower it into the well and weld the rod, immerse it again and attach another rod. So all the way to the bottom. The armature is needed to twist the spiral and grip the device. If the device fails to hook, after rotational movements the rest of the cable will twist onto the trap and the pump will rise.

Important: To avoid problems with cable breakage, from the very beginning it is selected with a sufficient margin of safety. A safety bolt is installed in the coupling with the unit.

What not to do

  • Pull forcefully on the hose or cable. They can come off.
  • Continue operating the pumping equipment. This will make the situation worse.
  • Start lifting the pump without finding out the reason why it is stuck.
  • Work with the power cable connected to the pump connected to the socket.
  1. When installing pumping equipment, you need to choose a very strong cable. It is better if it is stainless metal covered with silicone braid. Locking rings with bolts are attached to the ends of the cable.
  2. The well must be flushed and cleaned every two or three years of use.
  3. If water is not used, the equipment must be pulled out of the mine shaft.
  4. The pumping device is selected according to technical specifications that are suitable for different types wells separately.
  5. The diameter of the flask is chosen to be 40-50 mm smaller.
  6. To prevent the supply cable from sagging in the column, it is tied with special clamps to the cable and pipe.
  7. Do not pull on the hose.

Advice: when a pump is stuck in a well and it is impossible to push it, the principle of pressure on the lever will come to the rescue. The mash depth is shallow and you can see where the flask is. We take a pipe or fittings with a diameter of 32-40 mm and immerse it in the shaft. We weld or screw a strong eyelet onto the edge of the casing, into which we thread another tube 2-3 meters long. Now we simply press the lever on the axial pin. Gradual pressure on the flask will ensure a smooth push down.

Details about the submersible vibration machine:

Normal operation individual system water supply for a private house with borehole pump depends on many factors, including how correctly and timely the equipment is serviced. Visual inspection pipelines and joints, monitoring pressure and taking into account the volume of pumped liquid, changing filters, all this significantly extends the life of the equipment, but among all these operations, the most labor-intensive operation still remains the maintenance of a deep-well pump, during which it is possible non-standard situations, for example, when the pump may simply get stuck in the well.

Deep well pump stuck - main reasons

Most often, a pump getting stuck in a well casing is associated with several factors, each of which is unique in its own way, and the ability to solve the problem of stuck equipment is not always justified using a universal technique. On the other hand, the situation when the pump cannot be lifted to the surface is not so unique; cases when equipment is difficult to remove from the ground happen quite often and therefore this does not pose a particular problem for professionals.

Schematically, the situation when the pump somehow gets stuck in the well cavity is quite simple, and can be considered in the most common situations:

  • Jamming by a weakened electrical wire;
  • Breakage of the cable on which the equipment is suspended during lifting;
  • Entry of a foreign object into the cavity between the casing wall and the pump housing;
  • Deformation of the pump housing or pipe walls;

Most often, as practice shows, one encounters such situations with equipment that for a long time has not been serviced, so when planning service it is necessary to pay attention to this factor.

What to do if the pump gets stuck in the well

Getting the pump stuck during lifting, as already mentioned, is not such a critical situation, and if lifting is not carried out professional specialists for well maintenance, the first thing you need to do is be patient and pull yourself together; panic in this situation can only aggravate the problem.

A simple analysis of the situation will help you quickly determine the causes of equipment failure and choose the best way to solve the problem. To do this you need:

  • find out the total installation depth of the pump;
  • approximately determine the depth of the jam;
  • analyze how tight the cable is, determine whether the pipeline and pump are disconnected and the integrity of the power cable.
  • inspect the head of the casing pipe;
  • prepare necessary tool for work;
  • clear the area of ​​foreign objects.

This algorithm of operation makes it possible to significantly reduce the time required to prepare for lifting equipment and prevent larger mistakes in the future.

From simple to complex

For deep well pumps having large diameter and a short length, the connection of which is carried out using a flexible polyethylene hose, and these are most often vibration pumps; when lifting, a situation may arise when something gets between the pump body and the wall of the casing pipe. electrical cable pump

Such pumps are most often lifted by a cable and a hose, but the cable, the entrance to the pump body, which is located below the level of the hose connection and the cable fastening, is simply tightened periodically. At the moment when the cable is most weakened and has excessive length, it fixes the rise of the entire structure. The small distance between the housing and the wall into which the cable enters becomes a big obstacle to removing the equipment to the surface.

In fact, this is the simplest of all possible cases of jamming during lifting. The problem here can be solved quite simply - just lower the pump a little into the well and at the same time tighten the cable. After tensioning the cable, continue lifting, ensuring the tension of all elements - hose, cable and cable.

The situation when the cable breaks and the entire structure slides down happens quite often. Typically, a metal cable does not break, just the fixing elements loosen over time due to corrosion of the metal, the threads are not able to fix the fastening and the cable is released. For metal steel rope or cables, alloys that are not subject to corrosion or structures that have an additional protective sheath of plastic are usually selected. But an ordinary steel cable, being constantly in a state of tension, can develop abrasions and active corrosion at the point of fixation, because the pump experiences vibration during operation, which is transmitted to the cable.

In this case, it is recommended to continue lifting if the well is shallow and the pump has light weight using a hose or pipe as the main lifting device. The upward feed should be smooth, without sudden interceptions or jerks. The use of a cable as a lifting element is unacceptable! With this method, it is necessary to prevent the pump from rotating around its axis, since if the pump jams, a pipe or hose may become disconnected, which will further aggravate the situation.

A broken pump at the bottom of the well is also not the best the best option to operate, but if the power cable is intact and still attached to the pump body, then the chances of lifting the equipment are greatly increased. For centrifugal pumps, screw pumps And vibration models The cable, as a rule, has an entry into the housing slightly below the outlet and almost at the level of the holes for attaching the cable.

For lifting, a device made from a piece of metal pipe and welded wire, on the one hand, and a lifting cable on the other, can be used here. The cable is threaded into the pipe to the bottom, with a wire welded and bent into a hook. The hook is lowered along the cable and, having reached the lowest point on the pump body, is inserted into the eyelet for the cable. This operation is somewhat similar to winter fishing, when the bait is slightly twitched to attract fish, and the lifting hook, with small up and down movements, should enter the eye and engage the pump.

Well in clay soils, the sand layer is most often subject to siltation. The situation when soil gets through the drainage holes into the casing pipe and settles, preventing the equipment from being lifted, is most often typical for wells that have been maintained for a long time without maintenance.

For circulation or screw pumps, this is quite painful, since they have quite impressive dimensions, and the sludge does not just settle, but is tightly compacted between the pump body and the walls casing pipe. In this case, when it was not possible to pull out the pump the first time, it is necessary to apply the tactics of gradual release from the bottom sludge.

The pump is alternately raised and lowered, first by 5-10 mm, and then. When the dirt plug begins to become saturated with water and erode, gradually releasing the pump housing.

Entry of a foreign object between the casing and the casing

The problem of small stones, pieces of metal or fasteners getting into the cavity between the casing and the well wall can lead to very serious consequences, such as cable breakage or deformation of the casing at the junction of the pipes.

Most often, a small stone or fastener element falls into the well during repairs or installation of equipment. The operation of the electric motor with slight vibration can facilitate the passage of such a foreign object through the cavity until the moment when it does not completely fix the motor.

There are two main extraction methods:

  • pushing a foreign object to the bottom of the well;
  • releasing the pump with a powerful jerk.

The first method allows you to free the equipment if it is possible to lower the housing down a few centimeters. It is important here that it is possible to “swing” at least 1-2 cm, so that the structure begins to move, and the stone gradually moves along the body. Raising 2-3 cm to the next place of stupor should alternate with lowering the structure by 1-1.5 cm.

The second method must be used very carefully. A sharp jerk can damage the cable, so if the fixation is rigid and the movement cannot be traced, it is recommended to lift it with a uniform force, literally “dragging” the pump along the well.

The process of deformation of the casing quite often occurs due to soil displacement or activation of underground sources, the transformation of a simple underground stream into a seething stream or even a river. Such changes in the structure of the soil in the area are not immediately noticeable from the surface, but relative to the well, then a large number of problems.

For wells with a metal casing, deformation is most often expressed in a change in the internal cavity of the pipe - crushing, bending or fracture. For wells with asbestos-cement casing pipes, material destruction and crumbling occur couplings, soil getting inside the well.

For wells with casing pipes made of PVC pipes Most often, bending or compression occurs, as a result of which it becomes difficult to lift the pump.

The optimal solution under such circumstances is to turn to professional builders to remove equipment. Only if you have all the necessary arsenal of search equipment, from a remote video camera to a multi-section rod with hooks, in such a situation it becomes possible to get the pump.

However, when the well is relatively shallow, only 8-10 meters, it is possible to remove equipment from profile pipe construct a sectional rod with hooks at the end and try to independently explore and remove the pump.

Usually, the distance to the point of deformation of the barrel is first determined, then an approximate calculation of the internal cross-sectional area is made and the possibility of extraction through the narrowest point of the pump bend is analyzed, and only after that it is lifted.

The cause of a big headache for some private home owners is pumping equipment stuck in the well. That is why it is important to know how to remove the pump from the well correctly. If you do it incorrectly, the structure may be damaged. In addition, in this way it will be possible to destroy the well.

Items that will be needed:

  1. Cable.
  2. Clamps.
  3. A piece of steel pipe.

To remove the pumping equipment, you will need to free it from silt or sand. You can clean the well yourself using special vibration-type pumps. This procedure must be carried out with great care, taking into account the fact that the pump may become clogged. The sequence of actions is as follows:

  1. The pump power cable is disconnected from the network.
  2. Vibrating equipment is lowered to the bottom of the well.
  3. The second pump with a hose connected to it is lowered into the water so that it can draw it in. This device must be located above the first pump.
  4. The pumps are turned on and then smoothly lowered as the contaminated water is pumped out of the well.
  5. The jammed pump is pulled out smoothly.

Causes of jamming

The reasons why it is not possible to quickly pull the pump out of the well may be different. The most common situations are:

Scheme for cleaning a well from accumulated sludge using pumps.

  1. The cable is sagging.
  2. The well was covered with silt.
  3. Significant damage to the pipe walls occurred.
  4. Any foreign elements have entered the pipe.

Lifting the pump from the well will require a lot of effort and special training, so you will need to be patient.

The gap between the pipe walls and the equipment may be only a few centimeters, so it will not be possible to see what happened without the use of special equipment. You will need to figure out the problem based on the symptoms.

Elimination methods

A significant obstacle when removing a stuck pump can be the small diameter of the well.

The most common and easily fixed problem is when the pump gets stuck during lifting and does not pull up despite great effort. The thing is that the cable sagged, as a result of which it got wrapped around the pump structure. In this case, you will need to carefully lower the pumping equipment down, identify the weak part of the cable and lift the pump again. While performing these actions, you need to ensure that the cable, cable and cord do not sag.

Avoiding cable sagging is quite simple. It must be secured to the cord with clamps. Whenever lifting pumping equipment, they will need to be removed and then new ones installed. You should know what this is simple steps, when compared with the effort to pull out the pump.

If you cannot get the pump out of the well onto a sandy base, this means that the well is silted, the pump is held by sediment, which in most cases reaches two or more meters. In this case, you will need to “swing” the structure using a cable. It will need to be pulled up and then lowered until the pump can be pulled out of the sludge. Water will begin to enter the gap, and the sediment will be washed away after a while. After this, the pump will need to be carefully pulled out. This problem can arise if the well is not cleaned for 3-5 years. Regular cleaning will reduce the likelihood of silting of the well to a minimum.

Proper placement of equipment in the well will help prevent sediment accumulation on the pipes and pump end.

It may also be that the pump cannot be pulled out of the well onto the limestone. Wells on limestone are not subject to ordinary siltation, so this means that “reverse siltation” has occurred. The reason is that the equipment is too deep, causing water to stagnate. Calcium and iron salts in the water will combine with oxygen and turn into sediment, which will gradually accumulate on the pipes and the end of the pump. In this case, there is no need to try to flush the water source to get rid of the damper. The sediment is dense, so you will need to move the pump slowly and carefully. The equipment must be turned on so that the water can quickly erode the sediment. In the future, attention should be paid not only to periodic flushing of the well, but also to the thoughtful placement of equipment in it.

If the pump gets stuck in the middle of the well and a knocking sound is heard, this means that the movement of the pump is hampered by damage to the pipe, which can occur for the following reasons:

  1. The joint has come apart.
  2. A dent has appeared.
  3. The edge is flattened.

In this case, you will need to carefully start rotating the pump. The equipment may end up in a dangerous place, but there can be no guarantee that the problem will be resolved successfully.

If the pump suddenly gets stuck in the middle of the well, this means that some element (bolt, stone, etc.) fell into the well and fell into the gap between the pump and the wall, causing the equipment to jam. In this case, it is best to turn to professionals, because you can decide on your own this problem very difficult.

Lifting the unit

Owners country houses in an attempt to save some money Money When using the services of specialists, trying to pull the pump out of the well on their own, they may perform incorrect actions. Most often the following is done:

All actions to remove a stuck pump must be carried out using a strong metal cable that can handle lifting heavy loads.

  1. Too much effort, as a result of which the cable most often breaks. All actions to remove a stuck pump must be carried out carefully. Even when installing the equipment, you will need to buy a high-quality steel cable that can withstand heavy loads.
  2. Using hooks and other devices to pull out a pump with a broken mount. If they come off and remain in the well, then the task of pulling out a jammed pump will become even more difficult.
  3. Attempts to move a stuck pump using a crowbar attached to a rope or cable. This tool can easily destroy a well. In this case, it will be almost impossible to restore its usual operation.

You should know that there are some tricks that help you remove the pump without the help of specialists. For example, you can select a cable, tension it and secure it. From time to time the cable needs to be tapped. If slack begins to appear, the cable must be selected, tensioned, and then tapped again. These steps need to be performed for several days.

You can also try pushing the pumping equipment down using a weight. To do this, you need to take a piece of steel pipe, which is approximately 1 m long. A metal “eye” is welded to the top of the pipe, onto which a separate cable is fixed. After this, the cable, wire and hose of the equipment will need to be inserted inside this pipe.

To avoid pump suction, it is necessary to monitor the serviceability of the caisson and the quality of the water coming from the well.

The device is lowered down so that the pump can move under its weight. When this happens, you will need to carefully remove all the elements from the well at the same time. It is worth considering that the weight of the structure can reach 50 kg.

If the pump is stuck tightly in the well, then there is no way to get it out. In this case, all that remains is to turn to professionals. If you use special devices, for example, an underwater camera, then they will be able to accurately determine the problem and find The best decision. However, you need to remember that these services are expensive. In addition, not every well with a jammed pump can be repaired.

WITH a well pump, like other water supply equipment, requires periodic maintenance. In order to carry out maintenance work, the pump must be lifted from the well. But all attempts to get him out were unsuccessful. The pump is stuck. How to get the pump out of the well if it gets stuck. we'll talk about it in this article.

Why is the well pump stuck?

Usually , For artesian wells, use casing pipes of small diameter. In addition, they insert plastic pipes diameter 100 – 110 mm. To lift water from a well, deep submersible pumps are used, which operate in the limited space of the casing pipe. The distance between the pump and the inner edge of the well usually does not exceed a few centimeters. For this reason, any violation of this small gap leads to the pump getting stuck in the casing.

The reasons why it is not possible to freely pull the pump out of the well may be different. The most common among them:

  • Cable slack.
  • Silting of the well.
  • Mechanical damage to the pipe walls.
  • Foreign objects getting into the pipe.

Due to the small gap between the pump and the casing, it is simply impossible to see what happened there without special equipment. Therefore, you will have to find out the causes of the problem based on the symptoms.

Pump stuck during lifting

Symptoms: The pump is stuck in the lifting process and will not move upward despite considerable effort.

Diagnosis: This is likely the most common and easiest to fix problem: a loose cable that has become wrapped around the pump housing.

What to do? Carefully lower the pump down, remove any slack in the cable and lift the pump again. In this case, you need to ensure that the cable, cable and hose do not sag.

Avoiding cable sagging is very easy. It must be attached to the hose with special clamps. Each time you lift the pump, you will have to remove them and then install new ones, but these are trifles compared to the efforts to pull out a stuck pump.

It is impossible to get the pump out of the well onto the sand

Symptoms: It is impossible to remove a pump from a sand well, which has served faithfully for several years without any problems.

Diagnosis: The well is silted or sand has begun to flow into it, the pump is blocked by sediment, which can reach one meter or more.

What to do? The structure must be “swinged”, carefully acting with a cable. It must be pulled up, then released until the pump can be pulled away from the sludge. Water will enter the gap and the sediment will gradually be washed away. The pump can then be carefully removed.

This problem most often occurs if the well has not been cleaned for several years. Annual cleaning will reduce the risk of well siltation to a minimum. You can read about how to clean a well in my.

The pump cannot be removed from the well on limestone


Symptoms: The pump cannot be removed from a limestone well that has not been serviced for a long time.

Diagnosis: The situation is similar to the previous case. Wells on limestone are not subject to normal siltation, so we can conclude that the so-called “reverse siltation” has occurred. Its cause is excessive deepening of the pump, as a result of which the water around it stagnates. As a result, the calcium and iron salts contained in the water combine with oxygen and turn into sediment, which accumulates on the pipes and the end of the pump.

What to do? Attempts to flush the well to get rid of the plug will not lead to success, since the sediment is very dense. As in the previous case, you will have to slowly and carefully swing the pump. In this case, it is recommended to turn on the equipment by directing a stream of water into the well so that the water quickly erodes the sediment. Further Special attention should be given not only to regular well maintenance, but also correct placement equipment in it.

Pump stuck in the middle of the well

Symptom: The pump is stuck in the middle of the well and a knocking sound may be heard.

Diagnosis: The pump’s progress is hampered by damage to the pipe, which has arisen due to a split joint, a dent, a flattened edge, etc.

What to do? In this case, you need to carefully give the pump rotational movement. Perhaps the equipment will slip by dangerous place, but there is no guarantee of a successful solution to the problem.

The pump suddenly got stuck in the middle of the well

Diagnosis: An object (bolt, pebble, etc.) was dropped into the well, which fell into the gap between the pump and the wall, jamming the equipment.

What to do? In this situation, you can try to push the pump down using a weight. To do this, take a piece steel pipe suitable diameter about a meter long. A metal “ear” is welded to the top of the pipe, onto which a separate cable is fixed. After this, the cable, cable and pump hose must be passed inside this pipe. The structure is lowered down so that the pump is moved from its place under its weight. When this happens, you need to carefully pull the pump and a piece of pipe out of the well. It is worth considering that the weight of the device can reach more than fifty kilograms.

If the pump is stuck tightly, and no method can be used to move it, all that remains is to contact a specialist. Using special equipment, for example, an underwater video camera, they will be able to accurately diagnose the problem and suggest optimal solution. However, it should be remembered that such services are expensive. In addition, not every well with a stuck pump can be saved. Competent design and construction of a well, use quality materials And regular maintenance will help prevent many problems. And the question of how to get the pump out of the well if it is stuck will never arise.

How to get a pump out of a well if the cable breaks

Broken cable, one of the most complex cases. There was such a case in my practice. If the pump is small (baby) and the depth of the well does not exceed 20 meters, then you can try to pull out the pump using a hose and wire. For this operation to work, before lowering the pump into the well, you must tie the wire to the hose using electrical tape or plastic clamps. In this case, you should not make sudden movements. The lifting of the pump should be smooth and uniform.

Let's now try to figure out together how to pull the pump out of the well and whether it needs to be done at all in cases where it has stopped functioning. Perhaps the reason for stopping the water supply is not in it at all, but in the electrical cable or process automation system.

In order to understand this, you need to clearly understand the source device and connection diagram, which will now be discussed and, in addition, you can watch the thematic video in this article as additional material for clarification.

Construction and repair of the water supply system

Some possible reasons for stopping

Note. A borehole primarily differs from a water well in its small diameter and, in almost all cases, greater depth.
Drilling can be carried out “on sand”, or to the aquiferous artesian layer, which is much deeper.

  • If your pump does not pump water from the well, this does not mean that it is out of order and needs to be replaced, so let’s take it in order. First of all, you should take into account the factor of what kind of well you have - “sand” or artesian, since in the first case the filtration layer may become heavily silted and the pump may not be able to cope with the thick liquid.

  • One more possible reason If the pump in the well is not working, there may be problems in the terminal box at the well head, if the cable was connected through it (there could be a splice using a heat-shrink sleeve, but practically no problems arise there). In any case, the electrical cable will be short and will have to be extended, and the instructions suggest doing this through terminals like these, although this is not the best option.

  • Before you pull the pump out of the well, you should also pay attention to the pressure switch, as the unit may not start due to the fact that the minimum starting limit is missing. There may be several reasons: settings failure, oxidation of contacts, or complete failure of the sensor. In addition, you need to determine whether voltage is supplied to the electrical cable at all (this can be done with an ampere-volt meter (tester)).
  • Only after checking all these components and factors can the unit be pulled out of the well. Please note that this will have to be done together with the main pipe, so this work requires at least two people.

We take the pump out of the well

The question of how to hang a pump in a well is identical to the question of how to remove it, since both installation and dismantling are carried out according to the same scheme. The main fastener for the unit is a steel cable, one end of which is attached to the eye on the body, as shown in the photo above, and the other to the well head.

In the diagram you see the structural components of the well cap and, although its cover may not have a round, but an elongated shape (the cable entry may extend to the side), everything else remains the same. So, the steel cable is attached to the eye bolt and, in the same way as on the pump body, is clamped with special clamps (the clamp for the cable is made taking into account its diameter).

Note. In most cases, an electric cable is attached to the steel cable using clamps or ordinary copper or aluminum wire, so you will pull them together.

We have figured out the cable and now we need to find out how the water intake is carried out - through a caisson (pit) or an adapter, since this will radically change the method of dismantling the unit from the well.

If the main line is routed through a caisson, then in 99% of cases it is polyethylene pipe 32 mm diameter. And the first thing you need to do is cut this hose in the pit, stepping back 15-20 cm from the casing.

After this, you need to insert the protruding pipe into the service pipe and only then lift the pump itself using a cable, pulling it up.

To do this, unscrew the cover, but do not remove the cable from the eye bolt - if it slips out when you lift it up with your own hands, it will still stay on this fastener, so you will not encounter force majeure circumstances.

But if the main pipe for water intake is connected via an adapter, then you cannot do without a rod with external thread at one end. The fact is that the adapter consists of two parts, where one is tightly attached to the service pipe, and the other to the pipe that connects it to the submersible pump.

These two elements are connected to each other by a sled connection - the clutch is quite tight, especially since there is always a special waterproof lubricant.

On the top of the adapter part, which is attached to the pipe, there is a special hole with internal thread for fixing the rod. Therefore, you will have to find the right barbell ( metal pipe, A the required thread you can cut it yourself) and, lowering it into the well, screw it to this hole.

Once you get onto the threads and screw the rod, try to pull the whole thing up, just don't wobble it so you don't damage the threads or the adapter itself.

Most likely, the adapter will not disconnect the first time, since it is quite difficult to remove the pump from the well - the salts contained in the water clog the connection, and it needs to be moved from its place.

Therefore, you will have to make several strong upward movements to disconnect the adapter, and perhaps even use some kind of homemade winch or jack to do this.

Recommendation. If you cannot disconnect the adapter, then use two ordinary car jacks for help.
To do this, you will need a crossbar with a clamp that will grip the barbell and two T-shaped supports under it.
Place jacks under these supports or instead of them and lift them gradually to avoid severe distortion - the adapter will definitely come apart.

Most likely, those who were involved in the installation knew which pump to install in the well and its diameter was several centimeters smaller than the cross-section of the pipe. Therefore, the lifting should occur without complications, except that in the first case the pipe will rub against the production pipe.

Conclusion

In conclusion, I would like to remind you once again that you do not rush to get submersible pump when stopping it, and first made sure that the remaining components were working. Still, the price of such a unit is not a penny, and the labor costs associated with its dismantling are also considerable. Good luck!
