Definition
Explosion-proof motor is a kind of motor which can be used in inflammable and explosive places.
Explosion-proof motors are mainly used in coal mine, petroleum natural gas, petrochemical and chemical industries.
In addition, in the textile, metallurgy, urban gas, transportation, grain and oil processing, paper, medicine and other departments are also widely used.
As the main power equipment, explosion-proof motor is usually used to drive pumps, fans, compressors and other transmission machinery.
Categories
1.Points according to the principle of the motor.Can be divided into explosion-proof asynchronous motor, explosion-proof synchronous motor and explosion-proof dc motor.
2.Divide by place of use
It can be divided into mine underground explosion-proof motor and factory explosion-proof motor.
3.According to the principle of explosion protection points
It can be divided into flameproof motor, safety increasing motor, positive pressure motor, non-spark motor and dust explosion-proof motor.
4.According to the supporting host points
It can be divided into the coal mine conveyor with explosion-proof motor, coal mine hoist with explosion-proof motor, rock loader use explosion-proof motor, coal mine local fan used explosion-proof motor, valve with explosion-proof motor, fan with loud explosion-proof motor, marine explosion-proof motor, lifting metallurgical explosion-proof type and hydrogenation device matching with increased safety brushless excitation synchronous motor, etc.
In addition, it can also be divided according to 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.
