The method to judge the quality of a car compressor is very simple, just follow the following steps for inspection:
Step 1: Start the engine and maintain a speed of 1250-1500 rpm for 1 minute. Connect the manifold pressure gauge assembly to the air conditioning refrigeration system, turn on the air conditioning switch, and turn on the fan to its maximum position.
Step 2:
Step 2: Touch the inlet and outlet of the compressor. In general, the air inlet is cold and the air outlet is hot, with a large temperature difference between the two. If the temperature difference between them is very small, then look at the manifold pressure gauge.
Step 3:
Step 3: If the pressure gauge shows a very small difference between high and low pressure, the compressor is not working properly and should be removed for maintenance. If the compressor is very hot, check the manifold pressure gauge. The pressure gauge shows that the low-pressure side pressure is too high and the high-pressure side pressure is too low, indicating poor internal sealing of the system. The compressor should be replaced. If the high and low pressure of the refrigeration system is too low, it indicates that there is too little refrigerant in the system and leakage detection should be carried out. If the compressor leaks, it should be replaced or repaired.
The above is a simple method to determine the quality of a car compressor, just follow the above steps for inspection. Note that if problems are found with the compressor, timely maintenance or replacement should be carried out to ensure the normal operation of the car air conditioning.
