Abstract
The utility model relates to an external water cooling heat radiation resistance and refractory electric motor, particularly an electric motor used in a high temperature environment. The utility model is composed of an outer casing, a casing, a stator and a rotor which are installed in the casing, wherein, the center par of the rotor is provided with a rotating shaft; the outer casing is positioned at the periphery of the casing, and an interlayer is formed between the outer casing and the casing; the inner part of the interlayer is filled with heat-insulating materials and is provided with a cooling water passage which is distributed on the surface of the casing; the water inlet and the water outlet of the cooling water passage are positioned at the top part of the outer casing. The utility model has the advantages that the structure is simple, the heat insulating outer casing can effectively resist the heat radiation in the high temperature environment, the open or circulatory outer cooling water can cause the heat in the electric motor to be carried out, and the service life of the electric motor can be extended obviously. The utility model is especially suitable for the high temperature environment to use.
Description
The utility model relates to a kind of motor that is operated in the hot environment.
The ambient temperature at steel plant continuous casting scene is very high, and strong high temperature heat radiation will make the electrical machine insulation layer of working in this environment destroy rapidly, cause motor to be burnt, and seriously influence the useful life of motor.According to statistics, be operated in the motor in the above-mentioned hot environment, its average life is less than 3 months, have in addition the two weeks of can only working.In order to prolong the useful life of motor in hot environment, prior art generally strengthens the ability that motor is resisted high temperature heat radiation by the approach that improves the electrical machine insulation grade.But, improve the restriction that the electrical machine insulation grade will be subjected to multiple factors such as insulating material, thereby be very limited the actual effect that prolongs motor useful life.Moreover, improve the electrical machine insulation grade and certainly will will increase motor manufacture difficulty and manufacturing cost greatly.In service at motor, hot box that the employing that also has is simple and crude or heat shield try hard to motor and hot environment are completely cut off, but actual effect are unsatisfactory.
The purpose of this utility model promptly is being operated in the in addition suitable improvement of electric machine structure in the hot environment, preventing the destruction of high temperature heat radiation to the electrical machine insulation layer, thereby prolongs the useful life of motor.
To achieve these goals, the utility model is set up a shell and is formed interlayer with casing in the periphery of motor case, fills in interlayer with heat-barrier material to intercept and the shielding high temperature heat radiation.For heat that motor stator or rotor line bag are produced in time outside the discharge machine, the cooling water channel that is distributed in the casing surface also is housed in interlayer, cooling water can be taked open or circulating.Be described in further detail below in conjunction with the architectural feature of specific embodiment the outer water-cooled thermal radiation resistant heat resisting motor of the utility model.
Accompanying drawing 1 is the structural representation of the outer water-cooled thermal radiation resistant heat resisting motor of the utility model.
With reference to the accompanying drawings 1, the outer water-cooled thermal radiation resistant heat resisting motor of the utility model mainly is made of shell 1, casing 2 and the stator 3 and the rotor 4 that are installed in the casing, and the central authorities of rotor 4 have rotating shaft 5.Shell 1 is positioned at the peripheral of casing 2 and forms interlayer with casing 2, is filled with heat-barrier material 6 and the cooling water channel 7 that is distributed in the casing surface in the interlayer.Cooling water can be open or circulating, and its water inlet 8 and delivery port 9 all are positioned at the top of shell 1.
The utility model is simple in structure, and thermal insulation layer can intercept and shield high temperature heat radiation effectively, and the heat that outer cooling water can produce motor internal in time be taken out of, but thereby the useful life of significant prolongation motor in hot environment.Therefore, the utility model is particularly suitable for using in hot environment.
Claims (1)
1, a kind of motor of working in hot environment is made of casing and the stator and the rotor that are installed in the casing, and the central authorities of rotor have rotating shaft; The described casing periphery that is characterised in that of the present utility model has a shell and forms interlayer with casing, filling heat-barrier material and the cooling water channel that is distributed in the casing surface is installed in the interlayer, and the water inlet of cooling water channel and delivery port are positioned at the top of shell.
