It is understood that most people only know that explosion-proof motors are mainly used in flammable and explosive places, such as flammable and explosive chemical plants, flour processing plants, wine making, oil depots, etc. But I don't know how to choose explosion-proof motor. Today, I bring knowledge of explosion-proof motor.

Product classification

According to explosion-proof principle

It can be divided into flameproof motor, increased safety motor, positive pressure motor, non spark motor and dust explosion-proof motor.

According to the matching host

It can be divided into explosion-proof motor for coal mine conveyor, explosion-proof motor for coal mine winch, explosion-proof motor for rock loader, explosion-proof motor for local fan in coal mine, explosion-proof motor for valve, explosion-proof motor for fan, explosion-proof motor for ship, explosion-proof motor for lifting and metallurgy, and increased safety brushless excitation synchronous motor for hydrogenation device. 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 explosion-proof motor and high starting torque explosion-proof motor.

Explosion-proof motor is mainly used in coal mine, oil and gas, petrochemical and other industries. This is because the explosion-proof motor does not produce electric spark during operation, so it is a kind of motor that can be used in flammable and explosive places. In addition, it is also widely used in textile, grain and oil processing, papermaking, metallurgy, city gas, transportation, medicine and other departments. Explosion-proof motor is the main power equipment, usually used to drive pumps, fans, compressors and other transmission machinery.

How to wire the explosion-proof motor

The inlet of the explosion-proof motor junction box is sealed by pressing the rubber ring. The weakness of this structure is the aging of the rubber ring and the elastic failure, which makes the cooperation between the cable and the rubber ring inconsistent. For the junction box of the double outlet of the explosion-proof motor, the unnecessary outlet should be blocked with a metal sealing piece of thickness not less than 2mm. The outer diameter of the metal sealing piece should be close to the inner diameter of the outlet hole of the inlet and outlet device, so as to ensure that the sealing ring is evenly pressed by the pressure plate or the pressing nut to achieve a reliable seal.

Explosion - proof motor lifting and storage

All EXPLOSION-PROOF MOTORS NEED TO BE LIFTED WITH DERRICK OR HOLE, NOT allowed TO BE lifted or supported at the core punching plate or coil, when the whole EXPLOSION-proof motor is lifted, sling should be used to make weight distribution uniform, and brace should be used to avoid deformation of the roof. Careless handling during installation and incorrect use of derrick and hook are likely to cause more damage to explosion-proof motor than years of operation. Care should be taken not to damage the windings when handling the motor.
