: Structural characteristics and working principle
: & The electric pump structure is a single-machine single-suction centrifugal lower pump, which adopts dry Type high-efficiency motor, double-layer shell structure (see structural diagram).
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.
:&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 housing to the motor housing, and then flows through the water or air flow between the motor housing and the diversion housing. (When running without load) forced cooling. This method can ensure that the electric pump will not burn the motor during long-term idling and short-term overload operation.
:. The electric pump adopts a sealing form that combines skeleton oil seal, mechanical seal and air chamber. Practice has shown that this kind of seal has high reliability and service life.
