During the use of the electric chain hoist, the motor may have obvious heating phenomenon, and the motor may be damaged when the motor heats up seriously. After the motor is put into operation, it is normal for the temperature to rise, but if the motor heats up too much, it cannot be ignored. It is necessary to check the cause of the motor overheating.
1. It may be caused by overloading, the electric chain hoist is overloaded, the motor is overloaded, and the motor may be burned out by heating for a long time.
2. If there is no overload and the motor is still overheated, you can check whether the motor bearing is damaged and whether it works according to the specified time. The continuous working time may be too long.
3. The brake clearance is too small and not completely disengaged, resulting in a large frictional force. When the friction heats up, it is also equivalent to increasing the additional load, and the motor will also heat up.
First of all, you should check whether the electric chain hoist is overloaded. Overloading will cause the electric chain hoist motor to heat up, and the long-term overload will burn the motor; if the electric chain hoist is not overloaded, but the motor is still hot, you should check whether the motor bearing is damaged; The working system is stipulated, which is also one of the reasons for the heating of the electric hoist motor. When using, it should work strictly according to the working system of the motor.
When the electric chain hoist motor is running, the brake gap is too small and not completely disengaged, resulting in a large frictional force. The frictional heat is also equivalent to increasing the additional load, which reduces the motor speed, and the current increases and heats up. At this time, it should be Stop the work and readjust the brake clearance.
To sum up, there are many reasons that cause the electric chain hoist motor to heat up, so when we use it, we must check them one by one, to be foolproof, to ensure that the electric hoist is put into use in a normal state to ensure our lifting operation security.
