The failure of car air-conditioning compressors could affect the cooling effect in the vehicle, and it was important to have the correct maintenance methods and care. Details are provided below。
When a compressor is in trouble, the maintenance methods are mainly the following. One is to check the electrical connection of the compressor. The first is to confirm whether the power supply of the compressor is normal and to see whether the fuse has melted and, if so, to replace the fuse of the same specification in a timely manner. The plugs and beams are then checked for loose, broken and, if relaxed, for repair or replacement of broken beams。
The second is to check the belt of the compressor. See if the belt is worn, broken or loose. If the skin is worn or fractured, the new belt should be replaced in a timely manner. If the belt is loose, it can be increased by adjusting the tight wheel of the belt to ensure that it can function normally as a compressor。
Third, check the compressor refrigerant. Use specialized refrigerant detection equipment to detect refrigerant pressure and content in the system. If refrigerants are insufficient, leak sites should be identified and repaired and refrigerants added to the prescribed quantities. Where refrigerants are excessive, appropriate emissions are required。
Fourth is the interior parts of the compressor. When the compressor has an acoustic or irritant effects, there may be problems with internal pistons, valves, etc. This requires dismantling compressors and checking the wear and tear of internal components. For parts with severe wear and tear, such as piston rings, valves, etc., replacement is required. When dismantling and installing compressors, operations are carried out strictly in accordance with the steps of the maintenance manual to ensure the correct installation of components。
There is also much to note when repairing car air-conditioning compressors. The power supply of vehicles must be cut before maintenance can occur to prevent electrical accidents. Professional tools and equipment are used during maintenance to avoid damage to compressors due to inappropriate tools. In addition, care should be taken to keep the working environment clean and to prevent dust and miscellaneous items from entering the compressor interior, affecting its proper functioning。
The following is a table comparing the main points of the different maintenance scenarios:
Maintenance project methodology attention
Electrical connection check
Check fuses, plugs and wires
Disconnect the power to prevent electrocution
Belt check
Check for wear, fracture and laxity and process them
Adjustment using professional tools
Refrigerant inspection
Test pressure and content, repair leakage and adjust volume
Preventing refrigerant leakage
Internal part repair
Dismantling check and replacement of worn parts
Keep the environment clean as per manual
A mastery of the maintenance methods and care for these car ac compressors will help the owner to better cope with the compressor failure and ensure normal use of ac。
