    The explosion-proof grade of explosion-proof chain hoist is different from ordinary manual hoist


Description: Explosion-proof chain hoist is mainly divided into two grades and three levels of explosion-proof. Due to the special working environment of the explosion-proof chain hoist, at the same time it has some dangerous factors, so it is very important to choose the explosion-proof chain You elaborate on the meaning of the following models: dIIAT2 and dIIAT4, d stands for explosion-proof type II stands for type II explosion-proof, that is, factory explosion-proof. C stands for C-rated explosion-proof area, which is the most dangerous area. T4 stands for temperature group from T1 to T6. The following is a detailed introduction to the 5 explosion-proof levels of motors in explosion-proof chain hoists:

The following is a detailed introduction to the 5 explosion-proof levels of motors in explosion-proof chain hoists:
Explosion-proof chain hoist
1. Separate explosion-proof, increased safety, positive pressure, non-sparking and dust explosion-proof motors according to the principle of explosion-proof.
2. According to the motor principle, it is divided into explosion-proof asynchronous motor, explosion-proof synchronous motor and explosion-proof DC motor.
3. According to the place of use, it can be divided into explosion-proof motors for underground coal mines and explosion-proof motors for factories.
4. According to the rated voltage and efficiency, it is divided into high-voltage explosion-proof motor, high-efficiency explosion-proof motor, high slip rate explosion-proof motor and high starting torque explosion-proof motor.
5. According to the components used, it can be divided into explosion-proof motors for metallurgy, explosion-proof motors for coal mine transporters, explosion-proof motors for valves, explosion-proof motors for fans, explosion-proof motors for ships, and auxiliary safety-type brushless excitation synchronous motors for hydrogenation devices.
When purchasing explosion-proof chain hoists, please specify the actual application place and requirements, and it is important to choose a suitable explosion-proof chain hoist according to different working environments.
The main difference between explosion-proof chain hoists and ordinary chain hoists is that the materials of explosion-proof chain hoists are aluminum bronze and beryllium bronze, which do not cause sparks during impact and friction, so they are suitable for making flammable and explosive, strong magnetic fields. Close it for safe use, which is why the explosion-proof chain hoist is different from ordinary chain hoists.
