Classification and application of explosion-proof motors

A motor is an electromagnetic device that converts or transmits electrical energy according to the laws of electromagnetic induction. Explosion-proof motor is a kind of motor that can be used in flammable and explosive places and does not produce electric sparks when running.

Explosion-proof motor introduction

Explosion-proof motor is a kind of motor that can be used in flammable and explosive places, and does not produce electric sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, in the textile, metallurgy, city gas, transportation, grain and oil processing, paper, medicine and other sectors are also widely used. Explosion-proof motors as the main power equipment, usually used to drive pumps, fans, compressors and other transmission machinery.

Explosion-proof motors use an explosion-proof housing to isolate the electrical parts that may generate sparks, arcs and dangerous temperatures from the surrounding explosive gas mixture. However, this housing is not sealed, and the surrounding explosive gas mixture can enter the motor through the gaps in the joints of the various parts of the housing. When in contact with the shell of the spark, arc, dangerous high temperature and other sources of ignition may explode, then the motor explosion-proof shell not only will not be damaged or deformed, and the explosion flame or incandescent gas through the joint gap, but also can not ignite the surrounding explosive gas mixture.

Classification of explosion-proof motors

1, according to the motor principle: can be divided into explosion-proof asynchronous motor, explosion-proof synchronous motor and explosion-proof DC motor, etc.

2, according to the use of place: can be divided into underground coal mine explosion-proof motor and factory explosion-proof motor.

3、According to the principle of explosion-proof: it can be divided into explosion-proof motor, safety-enhanced motor, positive pressure motor, non-sparking motor and dust explosion-proof motor, etc.

4、According to the supporting host: it can be divided into explosion-proof motors for coal mine transporters, explosion-proof motors for coal mine winches, explosion-proof motors for rock loaders, explosion-proof motors for coal mine local fans, explosion-proof motors for valves, explosion-proof motors for fans, explosion-proof motors for ships, explosion-proof motors for lifting metallurgy and brushless excitation synchronous motors for hydrogenation devices.

In addition, it can also be classified according to the rated voltage, efficiency and other technical indicators, such as high-voltage explosion-proof motors, high-efficiency explosion-proof motors, high turndown rate explosion-proof motors and high starting torque explosion-proof motors.
