What happened to the refrigerator compressor
The expert explained that the structural feature of the refrigerator's fully enclosed reciprocating compressor is that the compressor and the motor are installed in the same casing. Its structure is very compact and the assembly is also very delicate. Therefore, special care must be taken in action and handling, otherwise it will be easy to produce Various abnormal sounds.
1. For the external vibration sound of the compressor For the external vibration sound of the compressor, such as the collision of the refrigeration pipeline, improper installation of the joint, the compressor base like the talent, cracked, deformed or loose bolts of the film, as long as it is carefully checked, move the position of the collision pipe or remove the talent. Cracked compressor base rubber rolls can be eliminated by reinstalling new parts.
2. The buzzing sound of the compressor For the buzzing sound of the compressor, unplug the cold box immediately, use a multimeter to measure the pressure or measure the three terminals of the motor. If the power supply voltage is lower than 180V and the motor winding is not burned, you can wait for the power supply voltage to return to normal before re-using it; if one phase of the motor winding is burned, you should send it to a professional warranty department for repair.
3. For the "click" sound from the compressor For the "tapping" knocking sound from the inside of the compressor, such as loose or damaged parts in the body, the valve plate is tight due to the loosening of the screw of the valve disc, the valve disc rupture, and the exhaust pipe and the housing touch, Failures such as uncoupling or breakage of the support spring should also be sent to a professional repair department for repair or replacement.
