Detailed Description

As shown in fig. 1 and 2, an explosion-proof machine with cooling function, including explosion-proof machine 2, explosion-proof machine 2 is arranged in inside the motor box 1, explosion-proof machine 2 is equipped with the blotter with the junction of motor box 1, motor box 1 is sealed box, the side of motor box 1 is equipped with pivot mounting hole 10, the pivot of explosion-proof machine 2 is worn out from pivot mounting hole 10, the cover is equipped with sealed bearing 16 between pivot and the

pivot mounting hole

10, 1 inner wall of motor box is equipped with the dry layer, air inlet 4 and gas outlet have been seted up respectively on the motor box 1. After the explosion-proof motor 2 is filled with dust or inflammable gas and other special application environments and operates for a period of time, the inside of the explosion-proof motor 2 can be filled with inflammable impurities, the air inlet 4 is externally connected with a nitrogen source, oxygen, inflammable impurities and the like in the motor box body 1 are discharged through the air outlet 5, the explosion-proof motor 2 is separated from the inflammable impurities, and the operation safety of the explosion-proof motor 2 is ensured. After the nitrogen is filled, the air inlet 4 and the air outlet 5 are respectively in threaded sealing connection by using the first air plug 11 and the second air plug 12, so that the sealing performance of the motor box body 1 is ensured.
