Description
Technical field
The invention belongs to shield pump technical field, and in particular to one kind shielding pump motor.
Background technology
Shielding pump motor is a kind of electromagnetic equipment that electric energy conversion or transmission are realized according to electromagnetic conversion law.Shielding
Pump motor can produce substantial amounts of heat energy at work, such as radiate not in time, can reduce shielding pump motor service life.
A kind of shielding pump motor by fan cooling is disclosed in the patent document of the B of notification number CN 102111037, but
It is not high to be that radiating efficiency remains unchanged.
The content of the invention
It is an object of the invention to provide one kind shielding pump motor, stator can be radiated in time in time, extension shielding
Pump motor service life.
The invention provides following technical scheme：
One kind shielding pump motor, including housing, stator, rotor and cooling device；
The stator is arranged in the housing, and the rotor is arranged in the stator and can be rotated in stator, described cold
But device is arranged between the stator and the housing, and housing is respectively provided with the rotor and stator.
Preferably, the cooling device includes the cooling layer with cavity, the import and export being arranged on the cavity and follows
Ring refrigeration machine, the import and export is connected with the circulating refrigerator respectively.
Preferably, coolant is full of in the cooling layer cavity, circulating refrigerator drives freezing liquid cold by import and export
But layer and circulating refrigerator body internal circulation flow, take away the heat of stator generation.
Preferably, the coolant is water by weight：Ethylene glycol=1:3, ethylene glycol boiling point is high, glues temperature good fluidity, can
It is preferable coolant with water arbitrarily than dissolving each other.
Preferably, temperature inductor is set on the cooling layer outer wall, and the temperature inductor is followed by circuit with described
Ring refrigeration machine is connected, and temperature inductor can detect the heat situation of stator, automatically turns on or close circulating refrigerator.
The beneficial effects of the invention are as follows：By setting cooling device between stator and housing, stator can be entered in time
Row radiating, extension shielding pump motor service life.
Brief description of the drawings
Accompanying drawing is used for providing a further understanding of the present invention, and constitutes a part for specification, with reality of the invention
Applying example is used to explain the present invention together, is not construed as limiting the invention.In the accompanying drawings：
Fig. 1 is canned motor pump electric machine structure schematic diagram.
Specific embodiment
Embodiment 1：
A kind of shielding pump motor as shown in Figure 1, including housing 10, stator 20, rotor 30 and cooling device 40；

Dynamic, the cooling device 40 is arranged between the stator 20 and the housing 10, is set respectively on the rotor 30 and stator 20
Put housing..
The cooling device 40 includes the cooling layer 41 with cavity, import and export 42,43 and being arranged on the cavity
Circulating refrigerator 44, the import and export 42,43 is connected with the circulating refrigerator 44 respectively.
Coolant is full of in the cavity of the cooling layer 41, circulating refrigerator 44 drives freezing liquid to exist by import and export 42,43
Cooling layer 41 and the body internal circulation flow of circulating refrigerator 44, take away the heat of the generation of stator 20.
The coolant is water by weight：Ethylene glycol=1:3, ethylene glycol boiling point is high, glues temperature good fluidity, can appoint with water
Meaning ratio dissolves each other, and is preferable coolant.
Temperature inductor 45 is set on the outer wall of the cooling layer 41, and the temperature inductor 45 passes through circuit and the circulation
Refrigeration machine 44 is connected, and temperature inductor 45 can detect the heat situation of stator 20, automatically turns on or close circulating refrigerator 44.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, although with reference to foregoing reality
Apply example to be described in detail the present invention, for a person skilled in the art, it still can be to foregoing each implementation
Technical scheme described in example is modified, or carries out equivalent to which part technical characteristic.It is all in essence of the invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
