The reasons for frequent vibrations and starts and stops during startup may be related to the following:
Improper belt tension: If the belt is too loose, it will not transmit power properly, causing the air compressor to vibrate during startup. The solution is to adjust the belt to the appropriate tension by tightening the screws.
Worn or damaged drive pulley: The drive pulley is the main connection between the belt and the air compressor main unit, transmitting power from the motor to the air compressor main unit. If the drive pulley is worn or damaged, it will cause the air compressor main unit to vibrate during startup. The solution is to replace the drive pulley. You can purchase genuine parts or consult a professional repair technician for replacement.
Internal fault of the air compressor main unit: Internal faults in the air compressor main unit can cause a variety of problems, including failure to start, unstable operation, and overheating or underheating. If these problems occur, the air compressor main unit needs to be disassembled and inspected to identify the fault and repair it.
Electrical or oil system failure: Failure in the electrical or oil system can cause the air compressor to fail to start properly, experience unstable operation, or experience overheating or underheating. If these problems occur, consult a professional for inspection and repair.
In summary, resolving air compressor vibration and frequent starts and stops during startup requires multiple approaches, including checking belt tightness, replacing drive pulleys, troubleshooting internal faults within the air compressor, and troubleshooting electrical or oil system failures. Only by identifying the root cause and taking appropriate measures can the problem be effectively resolved.
