Abstract
The utility model relates to a motor field of making discloses an explosion -proof breathing drainage structures of motor, and the breather valve setting is position department on front end housing, rear end cap or on the frame, the drain valve sets up in frame lower extreme position department. The utility model discloses reduced the motor internal pressure effectively, steam that the motor produced when using can be discharged outside the motor chamber through the breather valve at any time, comdenstion water that water cooled machine produced can be discharged outside the motor chamber through the drain valve at any time, avoids because the comdenstion water causes motor insulation resistance to reduce and the unable consequence of using, because it is a ex component to breathe the drain valve, has solitary explosion -proof certification, simple structure, simple to operate, use the advantage that has higher suitability and economic nature on the motor.
Description
Technical field
The present invention relates to the field that motor manufactures, is the structure that a kind of motor cavity is communicated with by explosion-proof breather drain valve with external environment condition specifically.
Background technology
The equipment such as coal mine underground coal mining machine, development machine, conveyer, conventional configuration explosion separation motor is all a seal, and inner chamber and external environment condition separate.Because motor is operationally a heater, and heavy-duty motor is all water-cooling structure, causes the condensed water in motor cavity to gather, and steam pressure increases, and insulating motor coil can be caused to reduce and cisco unity malfunction simultaneously.
Summary of the invention
In order to solve the problems of the technologies described above, the invention discloses a kind of motor explosion-proof breather discharge structure, concrete technical scheme is:
A kind of motor explosion-proof breather discharge structure, is characterized in that: breather valve is arranged on front end housing, rear end cap or support upper end position place; Described draining valve is arranged on support lower end position place.
The steam produced when motor uses can be discharged outside motor cavity at any time by breather valve; The condensed water that water-cooled machine produces can be discharged outside motor cavity at any time by draining valve; Breather drain valve is Ex (explosion-proof) element, and have independent certification of conformity of an instrument for explosive atmosphere, structure is simple, easy for installation.
Advantage of the present invention is:
1. breather valve is arranged on front and back ends and covers or support upper end position place;
2. draining valve is arranged on support lower end position place;
3. the steam produced when motor uses can be discharged outside motor cavity at any time by breather valve;
4. the condensed water that water-cooled machine produces can be discharged outside motor cavity at any time by draining valve;
5. breather drain valve is an Ex element, has independent certification of conformity of an instrument for explosive atmosphere, and structure is simple, easy for installation.
Accompanying drawing explanation
Fig. 1 is a kind of motor explosion-proof breather discharge structure sketch;
Wherein: 1 is breather valve; 2 is front end housing; 3 is support; 4 is draining valve; 5 is motor stator; 6 is rotor; 7 is rear end cap.
Embodiment
The present invention is illustrated: breather valve 1 is arranged on front end housing 2, rear end cap 7 or support 3 upper end position place below in conjunction with accompanying drawing; Described draining valve 4 is arranged on support lower end position place.
This invention structure efficiently reduces motor internal pressure, and the steam produced when motor uses can be discharged outside motor cavity at any time by breather valve; The condensed water that water-cooled machine produces can be discharged outside motor cavity at any time by draining valve, avoids the consequence that cannot use because condensed water causes electrical machine insulation resistance to reduce.Because breather drain valve is Ex (explosion-proof) element, have independent certification of conformity of an instrument for explosive atmosphere, structure is simple, easy for installation.Be applied on motor and there is higher applicability and the advantage of economy.
Claims (1)
