The main parts of automobile air-conditioning compressor: what is the electromagnetic clutch?

 

The car air conditioner is not cooling, in addition to the compressor problem, it may also be the strike of the electromagnetic clutch. For the car air conditioner that is not cooling, the first reaction of most car owners may be that the compressor of the air conditioner is broken, and most auto repair personnel will also give maintenance advice on replacing the car air conditioner compressor assembly.

In fact, the automobile air-conditioning compressor does not refrigerate. In addition to the compressor failure, there is another possibility that the main parts of the compressor and the electromagnetic clutch are malfunctioning. It is this seemingly inconspicuous electromagnetic switch, but it plays a key role.

 

The so-called compressor electromagnetic clutch is a power transmission and connection device. When we press the AC button in the car, the electromagnetic clutch generates suction, which transmits the power of the normally idling engine pulley to the driving wheel of the compressor. At this time, the compressor is running and there is cold air in the car. Once the electromagnetic clutch has a problem, or burns out, and loses the electromagnetic suction, the car air conditioner will lose its cooling capacity.

 

It is also very simple to detect whether there is a problem with the electromagnetic clutch of the air-conditioning compressor. We only need to find a repair shop or auto repair shop, and let their maintenance personnel use a universal meter to check whether the car air-conditioning compressor is energized or short-circuited. If no current is detected, or a short circuit occurs, it can basically be concluded that the electromagnetic clutch is scrapped.

 

At this time, we only need to spend a few hundred dollars to buy a new electromagnetic clutch and let the maintenance staff replace it. There is no need to spend thousands of dollars to replace a compressor assembly.

 

Compared with replacing the entire compressor assembly, does this save both cost and time?
