Product Description
The flameproof motor has a flameproof enclosure, and uses the air gap rotating magnetic field to interact with the induced current in the rotor winding to generate an electromagnetic torque.The casing can not only withstand the explosion pressure generated when the explosive gas mixture inside is detonated, but also prevent the explosive products from passing through the explosion-proof gap to ignite the explosive mixture around the motor casing.
1. The structural strength of the flameproof enclosure is to be able to withstand the explosion pressure generated by the explosive mixture inside.Due to the conditions of use and transportation requirements, special regulations are required for the shell material of mine flameproof motor shells, that is, cast steel or steel plate welded structures are used, but hand-held electric tools such as coal electric drills are allowed to use magnesium content less than 0.5% aluminum alloy casing.
2.The channel that can transmit the explosion pressure and flame to the outside of the motor, that is, the flameproof joint surface is the joint surface where the opposite surfaces of the various parts of the flameproof enclosure are fitted together.The minimum effective length, maximum clearance and surface roughness of the flameproof joint surface are stipulated according to the category and level of the motor operating environment.Generally, the flameproof joint surfaces of the flameproof motor and the junction box are: the flameproof joint surface between the casing and the front and rear end cover seams, the flameproof joint surface between the end cover and the bearing inner cover, the shaft hole of the bearing inner cover and the The flameproof joint surface of the shaft, the flameproof joint surface of the junction box seat and the junction box cover, the flameproof joint surface of the junction box seat and the casing, the flameproof joint surface between the junction box seat and the insulated terminal seat, etc.
3.The flameproof joint surface between the motor shaft and the shaft hole should not produce friction under normal working conditions
