Explosion-proof electric hoist electric idea how to deal with

Explosion-proof electric hoist applications rather special, in general, relatively high demand for proof. Explosion-proof electric  lift hoist  proof grade is divided into three and four explosion, the explosion of different products corresponding to different environments.
All electrical components electric motor are mounted in explosion-proof enclosure. Including explosion-proof enclosure consisting of several parts, end caps, bearing cover, shaft, terminal box and cover, terminals, terminal screws, seals, screw terminal sets, compression nut, etc., explosion-proof enclosure fastening bolts connecting the number of non-missing, each bolt with spring washers to prevent self-loosening,wire rope winch otherwise they will lose proof function.
Introduction of cable diameter electric motor with terminal box match the diameter of the inlet ring, good line, pressed by the compression nut seals the cable diameter and the inner ring and the seal between the outer diameter and junction box no gap between the seat bore so as to achieve proof function, brake inlet ring diameter Φ6.
Explosion proof enclosure between the mating surfaces of the joint surface, such as the base and cover of the Mouth of the mating surfaces, axis and the axis of the inner cover mating surface,manual hoist terminal screw threaded sleeve with the mating surfaces, etc., can not be bump-proof combination of surface and rust.
