M2JA series flameproof three-phase asynchronous motor is the manufacturing technology of ABB motor company the latest application of flameproof motor, combined with the characteristics of Chinese GB 3836-2000 standard and the development of the project

The most advanced domestic factories with 4 flameproof motor (Ex d||C) products (T1-T4 temperature group).

1. standard

M2JA series flameproof motor in accordance with the following criteria

Place 2.Ex D motor

1 explosion proof is divided into: 1 Zone 0, zone 2.

2 place

Petroleum, natural gas and chemical industry, in the production process may produce all kinds of flammable gases or vapors, such as oil refineries with propane, butane, gasoline, ethylene and acetylene; fertilizer plant ammonia, methanol, carbon monoxide, water gas etc..These substances are mixed with the air after the formation of an explosive mixture, if the mixture is in an explosive temperature, and in case of fire, it will cause serious accident of explosion.

Squirrel cage motor does not produce sparks in normal circumstances, but in the process of operation, due to the winding insulation damage and aging caused by short circuit spark; or because of conductive part connecting relaxation caused by arc, or due to mechanical failure and other causes of motor overload and block to produce high temperature, become a point source.

Therefore, we must focus on the various types of explosion-proof motor, spark arc and dangerous temperature take effective measures.

"Ex D" type flameproof motor is a form of explosion-proof explosion-proof motor, the casing can withstand damage without any joints or through the shell structure gap penetrated inside the casing of a flammable mixture in internal explosion, and will not cause the ignition of an external explosive gas environment, a variety of gas or steam formation the.
