FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, particularly to devices for automatic control of submersible electric motors of downhole pumps. On the accumulation tank the software time relay and two electric contact manometers are installed, one of them controls the pump during the day and maintains the level in the lower half of the tower, and the second electric contact manometer controls the pump at night and maintains the level in the upper half of the tower. From the pressure gages signals for switching on and disconnection are transmitted by one wire by dividing by diodes of positive and negative half-waves of alternating current for control of intermediate relays, to the output of which the coil of magnetic starter controlling the pump electric motor is connected.
EFFECT: technical result consists in possibility of separate control of electric motor of pump during day and night time.
