Mine sand pump

Explosion-proof submersible pump is our factory project Based on the actual working conditions of domestic coal mine underground drainage, technical personnel developed a new generation of integrated

type submersible electric pumps and

type sand discharge submersible pumps. Replacement products with high reliability and long life.

rb 1. Structural characteristics and working principle
br r bd
rr r bd: The structure of the electric pump is a single-machine single-suction centrifugal lower pump, which adopts a dry high-pressure High-efficiency motor, double-layer shell structure

rr r bd b. Part of the structure of the water pump adopts a single-suction centrifugal impeller and a centrally symmetrical multi-diffusion chamber pump body. This structure can balance the radial force of the pump shaft and reduce hydraulic impact. In addition, the water pump part of the high-power electric pump is equipped with axial force balancing structures such as auxiliary blades, auxiliary orifice rings and pressure relief holes, which greatly extends the service life of the bearings. In addition, the electric pumps are designed to be shut down for flushing to avoid clogging the impeller.
br r bd
rr r bd: The cooling method of the electric pump is: the heat generated by the motor flows through the iron core and the cooling air in the motor case to the motor case, and then flows through the motor case and The water flow or air flow between the guide shells

Forced cooling. This method can ensure that the electric pump will not burn the motor during long-term idling and short-term overload operation.
