Low-suction type multi-stage submersible electric pump

The invention relates to a low-suction type multi-stage submersible electric pump. The low-suction type multi-stage submersible electric pump is of the structure with a pump at the upper portion and a motor at the lower portion, and comprises the axial suction type multi-stage submersible pump, a motor-and-pump connector, the submersible motor and a tubular water absorption cover barrel. A motor base is connected to the bottom of the submersible motor. The multi-stage submersible pump and the submersible motor are connected in series, and the motor-and-pump connector, a motor wiring box and an upper guide bearing base are connected between the multi-stage submersible pump and the submersible motor. The low-suction type multi-stage submersible electric pump is used for strong drainage of mines, and the final level of residual water can decrease to be about 1m. The low-suction type multi-stage submersible electric pump is used for strong drainage of the mines, relay water pumps and matched electric control devices are not required to be used, the total equipment investment can be saved for users by about 5%, and power is saved by about 2-22%; under the situation of ensuring the working effect of a unit, the low-suction type multi-stage submersible electric pump is beneficial to simplifying the structure of the unit, and convenient to produce, install and maintain.
