Details
Submersible electric motors
Purpose
Used as a motor for centrifugal and cavity pumps for pumping formation fluid from oil wells. We produce more than fifty standard sizes of SEMs with power ranging from 12 to 350 kW, which allows you to choose the most optimal combination of motor and pump to ensure the operation of the installation with the highest possible efficiency.Construction
Electric motors have the construction type of mounting 1M 3631 according to GOST 2479. Construction types – one-section, two-section, and three-section. The manufacturing technology with the use of special materials allows us to produce high-heat-resistant motors operating in reservoir fluid with temperatures up to 302°F (up to 338°F at the request of customer). Motors are tested on a special stand, with the possibility of creating shaft load and picking up all the necessary parameters. Starting, control of the electric motor operation, and its protection in emergency conditions are carried out by control stations. Protection against reservoir fluid penetration into the internal cavity of electric motor, compensation for oil leakage and thermal changes in its volume during operation and stops, rotation torque transfer from the motor shaft to the pump shaft is performed by a protector with appropriateoverall and connecting dimensions and specifications.
Application
Used as part of an oil production unit and is a pump drive.Work principle
In the stator winding, when it is connected to a three-phase current, a rotating magnetic field arises, which crosses the rotor rods and induces an electromotive force in them. Since the rotor rods are closed, a current will appear in them under the action of this force. This current, interacting with the magnetic field, creates a torque, under the influence of which the rotor will begin to rotate. The direction of rotation will coincide with the direction of rotation of the stator field, however, in terms of rotation speed, the rotor will slightly lag behind the stator field; these motors are called asynchronous. The electrical energy supplied to the stator winding from the network is converted into mechanical energy of rotation of the motor shaft.Package contents

At customer’s request, submersible motors can be equipped with a telemetry system, which allows to obtain real-time data on the operation and the well conditions in the motor mounting area and to promptly shut down the unit in case of overstress. Transmission of signals from the submersible unit of the telemetry system to the control station is carried out via a power cable of the electric motor.
