Explosion-proof motor is a kind of motor that does not produce electric spark during operation. It is suitable for use in flammable and explosive places and widely used in coal mine, petroleum and natural gas, petrochemical and chemical industries. So what factors should be taken into account when the explosion-proof motor is used, do you know?

　　Classification of explosion-proof motor:

　　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.

　　2. According to the place of use

　　It can be divided into explosion-proof motor for underground coal mine and explosion-proof motor for factory.

　　3. According to the explosion-proof principle

　　Explosion-proof motor, safety increasing motor, positive pressure motor, sparkless motor and dust explosion-proof motor.

　　4. According to the supporting host

　　It can be divided into explosion-proof motor used in coal mine conveyer, explosion-proof motor used in coal mine winch, explosion-proof motor used in rock loading machine, explosion-proof motor used in coal mine partial fan, explosion-proof motor used in valve, explosion-proof motor used in fan, explosion-proof motor used in ship, explosion-proof motor used in hoisting metallurgy and anti-blocking synchronous motor used in hydrogenation device. In addition, it can also be divided according to the rated voltage, efficiency and other technical indicators, such as high-voltage explosion-proof motor, high-efficiency explosion-proof motor, high-slip explosion-proof motor and high-torque explosion-proof motor.

　　Considerations for explosion-proof motor:

　　Explosive material: some combustible material is produced in many production sites. About two-thirds of underground coal mines contain explosive material. In the chemical industry, more than 80% of the production workshop area has explosive material. Oxygen: oxygen is ubiquitous in the air. Ignition source: a large number of electrical instruments are used in the production process, a variety of electrical sparks, mechanical wear sparks, static sparks, high temperature and other unavoidable, especially when the instrument, electrical failure. Objectively, many industrial sites meet the explosion conditions. When the mixture concentration of explosive material and oxygen is within the explosion limit range, if there is an explosion source, an explosion will occur. Therefore, it is necessary to take explosion protection.
