Description
Technical field
The utility model relates to a kind of explosion-proof fan, particularly the under-voltage automatic protection fire-proof motor of the mining air pressure of one.
Background technology
Mine ventilator is mine special fan, is adapted at working, so mine ventilator also can be described as be mine blower fan, mine fan in dust, flue gas, moist mine.The working condition of present mineral explosion-proof motor is poor, and the frequent large load of motor starts, air pressure fluctuation is large, and ambient temperature is high, and these all affect dependability and the life-span of motor.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, and provide a kind of mining air pressure under-voltage automatic protection fire-proof motor, life cycle is long, and reliability is high, effectively can solve the problem in background technology.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
The utility model provides a kind of mining air pressure under-voltage automatic protection fire-proof motor; comprise casing, described casing outer wall scribbles explosion-proof layer, and described casing upper end is provided with supercharging device; described casing bottom is provided with pressure detector, and described casing is fixedly connected on base.
As a kind of optimal technical scheme of the present utility model, the material of described explosion-proof layer is polytetrafluoroethylene.
As a kind of optimal technical scheme of the present utility model, described supercharging device is provided with pressure valve.
The beneficial effect that compared with prior art the utility model reaches is: the utility model life cycle is long, and reliability is high, can effectively solve insufficient pressure problem, ensure that motor normally runs, improve operating efficiency and work quality.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.
In the accompanying drawings:
Fig. 1 is the main TV structure schematic diagram of the utility model;
Number in the figure: 1, casing; 2, explosion-proof layer; 3, pressure detector; 4, supercharging device; 5, base.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment: as shown in Figure 1; the utility model provides a kind of mining air pressure under-voltage automatic protection fire-proof motor; comprise casing 1; described casing 1 outer wall scribbles explosion-proof layer 2; described casing 1 upper end is provided with supercharging device 4; described casing 1 bottom is provided with pressure detector 3, and described casing 1 is fixedly connected on base 5.
Further, in order to improve the explosion-proof performance of fire-proof motor, scribble explosion-proof layer 2 at casing 1 outer wall, the material of described explosion-proof layer 2 is polytetrafluoroethylene, conveniently controlled pressure size, and described supercharging device 4 is provided with pressure valve.
Concrete, motor in use, when motor case 1 internal pressure is not enough, pressure detector 3 bottom casing 1 can detect under-voltage signal, and supercharging device 4 can start simultaneously, is filled with air pressure to casing 1 inside, ensure the normal even running of motor, meanwhile, casing 1 outer wall scribbles explosion-proof layer 2, prevents the explosion of casing 1.
The utility model life cycle is long, and reliability is high, can effectively solve insufficient pressure problem, ensure that motor normally runs, improve operating efficiency and work quality.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
