Abstract
The conventional wet rotor structure of protected type is to make internal flow by the gap between shaft and bearing, take away internal heat, this programme is using the acceleration heat dissipation wet rotor structure of protected type, increase the lid with blade wheel structure in wet two ends of rotor and increase bay cover end face trepanning mode, during high speed operation of motor, blade wheel structure and the synchronous operation of wet rotor, make bay cover is inside and outside to form pressure differential, it can speed up liquid convection inside and outside housing, reduce wet temperature of rotor, electric efficiency and service life are improved, so as to fulfill motor internal heat dissipating function.
Description
Technical field
The utility model is related to the wet rotor structure of protected type more particularly to the wet rotor electric machines of protected type of internal heat dissipating.
Background technology
With the development of science and technology, protected type motor is widely used in HVAC, household electric appliances, the advantage is that low noise
The process characteristics such as sound, freedom from repairs；The wet rotor of protected type with radiator structure can improve the reliability of pump operation, effectively prevent
The generation of failure.
According to statistics, the pump of the wet rotor of protected type accounts for about the 10% of national total power consumption in power consumption, the wet rotor institute of protected type
Mating motor power (output) accounts for about the 15% of national motor total capacity, and therefore, the wet rotor of protected type is improved with radiator structure
It is of far-reaching significance.
Utility model content
The purpose of this utility model is to provide a kind of acceleration heat dissipation protected type motor, and blade wheel structure is integrated on rotor, greatly
The earth reduces installation space and assembly difficulty, realizes internal liquid convection current, and internal heat is taken away in acceleration, reduces manpower maintenance
Cost, the management for pump bring convenient raising service life.
What the purpose of this utility model was realized in：It is a kind of to accelerate heat dissipation protected type motor, including motor casing and rotation
The rotor being erected in motor casing, the rotor are equipped with blade wheel structure, convection holes are set on the motor casing.
Preferably, the blade wheel structure is arranged on two ends of rotor.
Preferably, the motor casing includes housing and bay cover, and bay cover lid is closed on housing is open-ended.
Preferably, the convection holes are arranged on bay cover.
Preferably, there are two the convection holes are symmetrical arranged on bay cover.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
Protected type motor is used in rotor assembly and motor synchronous operation, is driven impeller on rotor, is produced inside housing
Raw pressure by aperture on bay cover, forms housing and bay cover external pressure is poor so that liquid accelerated service, realization pair
The function of rotor heat dissipation.

Fig. 2 is the sectional view of the utility model；
Fig. 3 is the rotor structure figure of the utility model；
Fig. 4 is the part drawing that the utility model bracket is somebody's turn to do.
Reference numeral：1st, housing；2nd, rotor；3rd, blade wheel structure；4th, bay cover；5th, convection holes.
Specific embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-4：
A kind of to accelerate heat dissipation protected type motor, including housing 1,1 open at one end of housing, the other end blocks, 2 turns of rotor
Dynamic cooperation is in housing 1, and 1 opening of housing is combined with bay cover 4, and housing 1 and bay cover 4 surround to form an appearance
Chamber；With reference to Fig. 2 and Fig. 3, blade wheel structure 3 is distributed on two end faces of rotor 2, blade uniformly divides around the shaft of rotor 2
Cloth,；With reference to Fig. 2 and Fig. 4, opened up on bay cover 4 there are two symmetrical convection holes 5,；Rotor 2 run at high speed impeller operation,
Housing 1 and bay cover 4 is made to form pressure differential, shielding internal liquid is quickly taken out of, it is right so as to take away 2 surface heat of rotor
Motor plays temperature with high efficiency effect, realizes and improves electric efficiency and prolong the service life.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
