Frequent heating of the crusher motor is a common problem, which not only affects the normal operation of the equipment, but also may lead to shortened equipment life and reduced production efficiency. The following are some causes of frequent heating of the crusher motor and the corresponding solutions:
First, the load is too large
Cause: The internal wire head or terminal of the motor is loose, broken, burned, resulting in excessive motor current, resulting in heat.
Solution: Check the wires and terminals inside the motor regularly to ensure that all connections are tight and not damaged. If a problem is found, the damaged parts should be repaired or replaced in time.
Second, the current is too large
Cause: Too low voltage or motor failure, resulting in too much current, resulting in heat.
Solution: Check whether the power supply voltage is stable. If the voltage is unstable, measures should be taken to stabilize the voltage, such as installing a regulator. At the same time, check whether the motor is working normally, and repair or replace it if necessary.
Third, the motor fan is damaged
Reason: heat dissipation is not good, resulting in motor heat.
Solution: Check whether the motor fan works properly. If the fan is damaged, replace it in time. At the same time, ensure that the air intake and air outlet of the fan are not blocked to maintain good ventilation.
Fourth, motor bearing damage
Cause: bearing wear or damage, increased friction, resulting in motor heating.
Solution: Check the wear of the motor bearing regularly. If the bearing is seriously worn, it should be replaced in time. At the same time, ensure that the bearing is well lubricated, and regularly add or replace lubricating oil.
Fifth, environmental sealing, poor heat dissipation
Reason: the working environment of the crusher is sealed and the heat dissipation is poor, resulting in the motor heating.
Solution: Improve the working environment and ensure that there is enough space around the equipment for heat dissipation. If necessary, you can install additional cooling devices, such as fans or air conditioners.
Sixth, the ambient temperature is too high
Cause: The working environment temperature is too high, resulting in motor heating.
Solution: Ensure that the equipment is operating at the appropriate ambient temperature. If the ambient temperature is too high, take cooling measures, such as installing air conditioners or ventilation devices.
Seventh, the motor and the crusher model do not match
Cause: The motor model does not match the crusher, resulting in overload or inefficiency of the motor, resulting in heat.
Solution: Make sure the motor model matches the crusher. If the motor model does not match, the appropriate motor should be replaced.
Eighth, the material leaks into the motor
Reason: Material leakage into the motor, resulting in motor winding insulation damage, resulting in heat.
Solution: Strengthen sealing measures to prevent material leakage into the motor. Check the sealing condition of the motor regularly and repair any leakage points in time.
Ninth, winding short circuit, turn short circuit, interphase short circuit and winding break
Reason: These failures will lead to increased current, local heating, insulation aging and other problems, resulting in motor heating.
Solution: Check the insulation of the motor winding regularly and repair any short circuit or open circuit problem in time. If the problem is found, it should be stopped immediately to check and repair.
Tenth, motor insulation performance aging or damage
Reason: Aging or damage to the insulation performance of the motor will directly lead to heating problems.
Solution: Check the insulation of the motor regularly and replace the aging parts in time. In addition, ensure that the fans and heat dissipation channels work properly to prevent bad heat dissipation.
Sum up
The frequent heating of crusher motor is a problem that needs attention. Through the above method, the motor heating problem can be effectively prevented and dealt with to ensure the stable operation and production efficiency of the crusher. At the same time, choosing a reliable equipment manufacturer to ensure equipment quality and after-sales service is crucial to the long-term stable operation of the equipment.
