Submersible centrifugal pumps
The multistage submersible centrifugal pumps of vertical version (electric centrifugal pumps), driven from submersible asynchronous electric motors with continuous mode of operation S1 to GOST 183 from AC mains with frequency of 50 Hz (motors), are used for pumping out formation fluid (oil, associated water and associated gas) from oil wells with deflection angle in the place of suspension not more than 60°.
The rated value of environmental climatic factors during operation shall meet version В* to GOST 15150.
The electric centrifugal pumps consist of the following assembly units:
- centrifugal pump including lower section (including input module), upper section (including check valve and drain valve, sludge trap), one or several intermediate sections;
- motor, including one or several electric motors (sections) and motor protector.
