Product classification and parameters of explosion-proof motor

Product classification

1 by using the place points

Can be divided into underground coal mine explosion-proof motor and factory explosion-proof motor.

2 by motor principle

Can be divided into explosion-proof asynchronous motor, explosion-proof synchronous motor and explosion-proof DC motor, etc..

3 by supporting the host points

Can be divided into coal conveyer with explosion-proof motor, mine winch with explosion-proof motor, mounted loader with explosion-proof motor, for mine local fan with explosion-proof motor, valve with explosion-proof motor, fan with loud explosion proof electric motor and ship with explosion-proof motor, metallurgy heavy with explosion-proof motor and hydrogenation unit supporting the use of increased safety brushless excitation synchronous motor etc.. In addition, according to the rated voltage, efficiency and other technical indicators, such as high-pressure explosion-proof motor, high explosion-proof motor and high slip slip proof motor and high starting torque explosion-proof motor, etc..

4 according to explosion-proof principle

It can be divided into the explosion-proof motor, the safety motor, the positive pressure motor, the non sparking motor and dust explosion-proof motor, etc..

Parameter

The rated voltage, current rating, power, speed and the same as the ordinary motor. Big is the explosion-proof motor more ex mark: ex, explosion-proof type + equipment category + (gas group) + temperature group explosion proof type: 1. Isolated burst type ex d2. sand filled ex q3. increased safety type ex E4. Encapsulation type ex m5. barotropic ex p6.n ex N7. Intrinsically safe type E X ia ex ib8. special type ex s9. oil immersed type ex o10. dust explosion-proof dip dip a B2 equipment category explosive gas environment electrical equipment is divided into: class I: coal mine electrical apparatus for use in class II: in addition to its coal other explosive gas environment for electrical equipment. The II type explosion - type "d" and intrinsically safe "I" electrical equipment are classified into IIA, IIB, and IIC. The electrical equipment of combustible dust environment is divided into: A dust dense equipment; B dust dense equipment. Three group, temperature: T6 combustible gas ignition temperature electrical equipment of the highest temperature T1 T>450 DEG C T2 450 DEG C >T>300 T3 300 DEG C >T>200 DEG C T4 200 DEG C >T>135 DEG C T5 135 DEG C >T>100 DEG C T6 100 DEG C >T>85 DEG C development along with the development of science and technology, production, there explosive field is also increasing. For example, edible oil production has been the traditional method of crushing process. After the seventies of the 20th century, China began to introduce foreign advanced technology of oil extraction, but in the process to use chemical solvents containing hexane, hexane is flammable and explosive substances; therefore the oil extraction plant became explosive dangerous location, need to use explosion-proof explosion-proof motors and other electrical products. And as, the rapid development of China's highway, a large number of fuel gas stations appear, but also to explosion-proof motor provides a new market.
