What are the causes of automotive compressor failure?

[OJuliette]

Automotive compressor failure can be attributed to the following causes: 1. Burnout of motor coils; 2. Poor heat dissipation in the condenser; 3. Leakage of the exhaust valve; 4. Damage to the insulation layer (short circuit) and open circuit in the stator winding. The automotive compressor is the heart of the car's air conditioning refrigeration system, responsible for compressing and transporting refrigerant vapor. Depending on the working principle, air conditioning compressors can be categorized into fixed displacement compressors and variable displacement compressors. Based on the working method, compressors can generally be divided into reciprocating and rotary types. Common reciprocating compressors include crankshaft connecting rod type and axial piston type, while common rotary compressors include rotary vane type and scroll type.
