Problems solved by technology

At present, the manufacturing process of the end cover of the explosion-proof motor shell on the market is complicated, and the flameproof stability is not good. Especially when sparks or explosions are generated inside the motor, the motor shell and end cover may be deformed, resulting in failure of the explosion-proof surface or failure of the explosion-proof surface. Cracks in the end cover of the shell pose a great safety hazard

Abstract

The invention relates to an explosion-proof motor shell and belongs to the field of a monitor. The explosion-proof electrical motor shell includes a shell body in a square barrel shape. The shell body is provided with a heat dissipation stiffener, and a connection fastener is arranged at the outer side of the end surface of an opening which is arranged on the shell body. A first flameproof belt is arranged at the inner side of the end surface of the opening. The explosion-proof electrical motor also includes an end cover body, and the heat dissipation stiffeners are arranged on both sides of the end cover body. A second flameproof belt is arranged at the inner side of the end surface of the opening of the end cover body. The second flameproof belt is matched to the first flameproof belt. The connection fastener is arranged at the outer side of the end surface of an opening of the end cover body. The heat dissipation stiffener, the shell body and the end cover body are cast into a whole. The connection fastener is in a four-group and eight-hole mode, and the connection fastener has the advantages of being good in flame-proof stability, simple in manufacturing process, not easy to deform in an explosion, high in coefficient of explosion-proof.

Description

technical field [0001] The invention relates to an explosion-proof motor casing, which belongs to the field of motors. Background technique [0002] Flameproof motor is a kind of explosion-proof motor, whose shell can withstand the internal explosion of flammable mixture penetrating into the shell through any joint surface or structural gap without damage, and will not cause external damage by one or more Ignition of explosive atmospheres formed by flammable gases or vapors. At present, the manufacturing process of the end cover of the explosion-proof motor shell on the market is complicated, and the flameproof stability is not good. Especially when sparks or explosions are generated inside the motor, the motor shell and end cover may be deformed, resulting in failure of the explosion-proof surface or failure of the explosion-proof surface. Cracks in the end cover of the shell pose a great potential safety hazard. Contents of the invention [0003] According to the defic...
