How to Fix a Seized Car Compressor?
1 Answers
The cause of a seized air conditioning compressor is usually due to poor lubrication or lack of lubricating oil. The car air conditioning compressor is the heart of the car's air conditioning refrigeration system, responsible for compressing and transporting refrigerant vapor. Compressors are divided into two types: fixed displacement and variable displacement. Based on different working principles, air conditioning compressors can be categorized into fixed displacement compressors and variable displacement compressors. According to different working methods, compressors can generally be divided into reciprocating and rotary types. Common reciprocating compressors include crankshaft connecting rod and axial piston types, while common rotary compressors include rotary vane and scroll types. The repair methods for a seized car compressor are as follows: Percussion Method: After turning on the compressor, use a wooden hammer to tap the lower half of the compressor to vibrate the stuck internal components and get them moving. Capacitor Start Method: Use a capacitor with a larger capacity than the original one to start the circuit. High Voltage Start Method: Use a voltage regulator to increase the power supply voltage before starting. Pressure Relief Method: Release all the refrigerant in the system before starting. Repair Shop Service: If the car air conditioning compressor seizes, immediately turn off the compressor's power supply and drive the car to a repair shop for professional servicing.
