Beschreibung
Zusammenfassung:	FIELD: oil producing industry. SUBSTANCE: invention relates to equipment for lifting of liquids from producing wells and it can be used for automatic control of operating parameters of submersible electric centrifugal pump. proposed pumping unit with feedback has submersible electric centrifugal pump, submersible electric motor and submersible electric pump shaft rotation regulator with feedback. Automated mechanical regulator is used as shaft rotation regulator with feedback. Regulator is made in form of differential mechanism one central wheel of which is connected with electric motor shaft and other wheel, with pump shaft. Carrier of differential mechanism planet pinions is connected with rotor of automated mechanical regulator through series reduction gears. Rotor is furnished with impeller washed by well fluid. EFFECT: improved efficiency of unit by provision of reliable control, and operation reliability at simplified design. 1 dwg
