The difference between the explosion-proof motor and the ordinary motor

The difference between the explosion-proof motor and the ordinary motor:

1. Explosion-proof motor is generally used in flammable and explosive situations.

2. The seal of the explosion-proof motor junction box is better than the ordinary motor.

3, the minimum protection level for explosion-proof motor is IP55, and ordinary motor has IPIP23, IP44, IP54, IP55, IP56, so it can be distinguished from the shape.

The following detailed introduction of explosion-proof motor:

Explosion-proof motor is a kind of motor that can be used in flammable and explosive plant, and it does not produce electric spark during operation.

The explosion-proof motor is mainly used in coal, petroleum, natural gas, petrochemical and chemical industry. In addition, it is also widely used in textile, metallurgy, city gas, transportation, grain and oil processing, paper making, medicine and other departments. As the main power equipment, the explosion-proof motor is usually used for driving pumps, fans, compressors and other transmission machines.

With the development of science and technology and production, the place of explosion danger is also increasing. For example, the production of edible oil is used in traditional pressing process, after 1970s, China began to introduce foreign advanced technology of oil extraction, but this process should be used in the chemical solvent hexane, hexane is flammable and explosive substances; oil extraction plant therefore became explosive dangerous places, need to use explosion-proof explosion-proof motors and other electrical products. In addition, in recent years, the rapid development of China's highways, a large number of fuel gas stations, also provide a new market for explosion-proof motor.

Product classification

1. according to the principle of motor

It can be divided into explosion-proof asynchronous motor, explosion proof synchronous motor and explosion proof DC motor and so on.

2. according to the place of use

It can be divided into coal mine explosion-proof motor and explosion-proof motor used in factory.

3. according to the principle of explosion protection

It can be divided into flameproof motor, increase safety type motor, positive pressure motor, spark free motor and dust proof motor.

4. according to the matching host

Can be divided into coal conveyer with explosion-proof motor, mine winch with explosion-proof motor, explosion-proof motor, rock loading machine for mine local fan motor, explosion-proof valve with explosion-proof motor, fan motor, marine explosion-proof explosion-proof motor, explosion-proof motor and hydrogenation device supporting heavy metallurgy with increased safety brushless excitation synchronous motor. In addition, it can also be classified according to the rated voltage, efficiency and other technical indicators, such as high-voltage explosion-proof motor, high efficiency explosion-proof motor, high slip motor, and high starting torque and explosion-proof motor. This article is classified according to the principle of explosion protection.
