Classification and characteristics of explosion-proof motors

2023-11-22 01:20:41

Explosion proof motors are mainly used in special industries such as petroleum, chemical, and natural gas. In addition, they are also widely used in metallurgical, textile, and pharmaceutical sectors, providing power for these industries while ensuring production safety. Since so many industries require them, of course, explosion-proof motors are also divided into different types. Let's take a look at Nanyang Explosion proof Motors.

1、 The difference between explosion-proof motors and ordinary motors:

1. Explosion proof motors are generally used in flammable and explosive situations;

2. The sealing of the explosion-proof motor pull box is better than that of ordinary motors;

3. There are differences in the protection levels of explosion-proof motors;

The rated voltage, rated current, power, and speed of explosion-proof motors are the same as those marked on ordinary motors, but there is an explosion-proof symbol on explosion-proof motors: Ex

2、 Explosion proof type

1. Flameproof Ex d

2. Sand filled Ex q

3. Increased safety Ex e

4. Sealing type Ex m

5. Positive pressure type Ex p

6. Type n Ex n

7. Intrinsically safe Ex ia Ex ib

8. Special Ex s

9. Oil immersed Ex o

10. Dust explosion-proof DIP A DIP B2

3、 Product classification

Classified according to explosion-proof principles

(1) According to the type of motor, it can be divided into explosion-proof asynchronous motors, explosion-proof synchronous motors, and explosion-proof DC motors.

(2) According to the place of use, it can be divided into explosion-proof motors used underground in coal mines and explosion-proof motors used in factories.

(3) According to the explosion-proof principle, it can be divided into explosion-proof motors, increased safety motors, positive pressure motors, non-sparking motors, and dust explosion-proof motors.

(4) According to the supporting host, it can be divided into explosion-proof motors for coal mine transport machines, coal mine winches, rock loaders, local fans, valves, fans, ships, lifting and metallurgy, and increased safety brushless excitation synchronous motors for hydrogenation devices.

In addition, it can also be classified based on technical indicators such as rated motor and efficiency, such as high-voltage explosion-proof motors, high-efficiency explosion-proof motors, high slip explosion-proof motors, and high starting torque explosion-proof motors.
