Purpose
The electric pump unit ETsV is designed for lifting drinking water from artesian wells for the purpose of urban, industrial and agricultural water supply, irrigation and other similar
Design features
The unit consists of an asynchronous electric motor and a multi-section centrifugal pump part, connected to each other by a rigid coupling. The pump rotor and the electric motor rotor rotate in rubber-metal bearings. At the bottom of the electric motor there is a thrust bearing that absorbs the axial load. A protective mesh filter is installed at the entrance to the pumping part, protecting the pump from the ingress of large mechanical particles. The electric motor is water-filled with a squirrel-cage rotor, with a synchronous rotation speed of 3000 rpm. The “squirrel cage” of the rotor is made of copper. The stator winding is made of waterproof wire. The electric motor is cooled by pumped water. The unit is connected to three-phase network 380V, 50Hz through a control and protection station that protects the electric motor from operating in abnormal conditions. The connection is made with an ERW cable with a cross-section corresponding to the current consumed.

- Absence of a well report during the calendar year of operation of the unit.
- Use for controlling units of frequency converters, without strictly following the recommendations.
Recommendations for the use of frequency converters for well pumps type ECV 10.
When operating ECV type downhole units with frequency converters, the following requirements must be observed:
To ensure sufficient cooling of the electric motor, the pump must operate in the operating range, its flow should not decrease by more than 20% of the nominal (for example, for the ETsV6-10 pump this is 8 cubic meters/h). Typically, the unit is controlled not by flow, but by pressure. In this case, the supply may decrease below the set level. That's why it is necessary to install a fluid flow sensor (relay), which would turn off the electric motor when the supply drops below the operating range or, using a flow meter, set the pressure at which the pump should turn off;
To protect the windings of electric motors from overheating, insulation melting and breakdown, it is recommended to install a temperature sensor that turns off the motor at temperatures above 70°C;
For normal operation radial and thrust bearings, the rotation speed of the electric motor shaft must be not less than 2700 rpm (45 Hz);
To protect the pump motor from high-frequency voltage pulses, which can lead to premature wear and breakdown of winding insulation, when long length connecting cable between the electric motor and the converter, it is necessary install output filters: du/dt filter or sine wave filter. Recommendations for the use of appropriate filters should be obtained from the manufacturers of frequency drives.
Due to the fact that water extraction from the Rozhnovsky tower is very uneven, and to cool the electric motor, the pump flow should not decrease below the set value, it is impossible to use a frequency converter without an intermediate storage tank or a hydraulic accumulator of appropriate capacity, because To do this, it is necessary to organize forced cooling of the electric motor in the well. You can also use a regular container and supply water from it using a type D pump with a frequency converter.
You also need to remember that if there is a large static component in the pressure characteristic of the system, the use of frequency regulation does not increase economic efficiency well pumps, but only allows you to reduce the volumes and, accordingly, dimensions of intermediate tanks, as well as reduce hydraulic shocks in the system.
