Abstract

The invention discloses an energy-saving submersible electric pump with low temperature rise and total head. The energy-saving submersible electric pump comprises a submersible electric pump main body, and is characterized in that the submersible electric pump main body comprises a water outlet end and a water inlet pipe arranged at the upper end and the lower end of the submersible electric pump main body, the lower end of the water inlet end is connected with an outer connecting cylinder through a flange device, the outer connecting cylinder is sequentially provided with a circular truncated cone section and a straight cylinder section from top to bottom, a transmission shaft is arranged in the outer connecting cylinder concentrically and vertically, and the outer connecting cylinder is sequentially provided with a grinding plate mechanism, a cutterhead mechanism and a filter net mechanism from bottom to top; and the grinding plate mechanism comprises a movable grinding plate fixedly connected with the outer wall of the transmission shaft and a fixed grinding plate fixedly connected with the inner wall of the straight cylinder section. The energy-saving submersible electric pump can crush impurities into small particles and then transport the small particles, motor jam caused by large particles is avoided, and the service life is prolonged. In addition, a thermal compensation cavity is arranged to avoid the phenomenon of thermal expansion and contraction which causes the cracking of the fixed grinding plate.

Description

technical field [0001] The invention relates to the technical field of full-lift submersible electric pumps, in particular to a low-temperature rise and energy-saving full-lift submersible electric pump. Background technique [0002] The submersible electric pump is a whole that is organically combined with the pump and the motor. It is mainly divided into two types according to the transported medium: the sewage and sewage submersible electric pump for pumping sewage and sewage and the small submersible electric pump for pumping clean water (commonly known as clean water pump) . [0003] At present, in order to improve the performance of submersible electric pumps and increase the advantages of low temperature rise, energy saving and full head, mature products have been developed. High-lift submersible electric pumps are suitable for extracting groundwater from deep wells and mines, and can be used for emergency rescue in gold mines, silver mines, iron mines, coal mines, a...
