Description
Technical field
The present invention relates to a kind of pump motor.
Background technology
Existing water pump boiler water circulation is separated with motor, and the rotor thermal cycle can only be through rotor to the motor stator transmission, and stator transmits to the outside through motor casing again, and radiating efficiency is low.Water pump runs up for a long time, and rotor can not get good cooling, and the decay of internal rotor permanent magnet magnetic influences pump working efficient, final permanent magnet high temperature failure, and water pump damages.
Summary of the invention
Low for the rotor radiating efficiency that overcomes existing pump motor, as the influence water pump operating efficiency and the deficiency in useful life, the present invention provides the novel pump motor water-cooling structure in the useful life of a kind of operating efficiency that improves the rotor radiating efficiency, improves water pump, prolongation water pump.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of novel pump motor water-cooling structure comprises spiral case, motor casing and bottom, and said spiral case is connected with the motor casing top seal; Said motor casing bottom and bottom are tightly connected, mounted impeller in the said spiral case, and said impeller middle spindle connects with motor shaft; Said motor shaft is installed on the bearing, and said bearing fixing is installed in the said motor casing, and said rotor is installed on the motor shaft; Said rotor is provided with stator outward, and said stator is installed in the motor casing, axially has water flow hole on the said impeller middle spindle; Said motor shaft axially has down water stream channel, and the said water flow hole of going up is communicated with the spiral case water inlet, and the said water flow hole of going up is communicated with following water stream channel; Between said stator and the rotor capsul is set; Said capsul top and motor casing are tightly connected, and said capsul bottom and bottom are tightly connected, and are provided with the cooling cavity between said rotor and the bottom; Passage between said rotor and the said capsul is the cooling duct; Said water stream channel down is communicated with said cooling cavity, and said cooling cavity is communicated with said cooling duct, on the electric machine casing between capsul and the motor shaft, has ostium excurrens; Said ostium excurrens is communicated with said cooling duct, and said ostium excurrens is communicated with the delivery port of spiral case simultaneously.
Beneficial effect of the present invention mainly shows: improve the operating efficiency of rotor radiating efficiency, raising water pump, the useful life of prolongation water pump.
