The invention discloses a self-cooling explosion-proof motor, which comprises a self-cooling explosion-proof casing, wherein a casing front end cover is arranged at one end of the self-cooling explosion-proof casing, a casing middle cover is arranged at the other end of the self-cooling explosion-proof casing, and a casing rear cover is arranged on the rear side of the casing middle cover; a self-cooling heat conduction pipe is arranged in the self-cooling explosion-proof casing, the inner wall of the self-cooling heat conduction pipe is tightly attached to the motor stator, a motor rotor is arranged in the motor stator, a motor rotating shaft is sleeved with the motor rotor, one end of the motor rotating shaft is connected with a front bearing arranged on the casing front end cover, the other end of the motor rotating shaft is connected with a rear shaft arranged on the casing middle cover, and the casing front end cover is provided with a rotating shaft explosion-proof joint surfaceand an oil seal through which a motor rotating shaft passes; and a full-sealing structure of the explosion-proof motor is realized through explosion-proof joint surfaces arranged between the self-cooling explosion-proof casing and the casing front end cover, the casing middle cover and the casing rear end cover, rotating shaft explosion-proof joint surfaces arranged between the motor rotating shaft and the casing front end cover, the casing middle cover and the casing rear end cover, and oil seals. The self-cooling explosion-proof motor is good in sealing performance and excellent in explosion-proof and explosion-proof performance.
Description
technical field [0001] The invention belongs to the technical field of motors, in particular to a self-cooling explosion-proof motor. Background technique [0002] The demand for explosion-proof motors in various industries such as industrial production, food processing, and pharmaceutical manufacturing is increasing day by day. At the same time, explosion-proof motors are indispensable in power systems in the petroleum, chemical, and coal mining industries. Due to the large number of applications of explosion-proof motors in various industries Due to the particularity of the use environment, the performance improvement of explosion-proof motors in terms of safety, reliability and explosion-proof performance is of great significance to the safe production of equipment and the personal safety of personnel. [0003] Explosion-proof motors work in a flammable and explosive environment, which will inevitably cause the mixture in the external environment to enter the motor. In or...
