The air conditioners in the car are not independent, and the refrigeration compressor of the air conditioner is driven by the main engine of the car through the pulley. The front end of the compressor is equipped with an electromagnetic clutch, which is used to automatically control the stop or operation of the compressor. When the electromagnetic clutch of the car compressor is broken, the symptoms are:

1, electromagnetic clutch abnormal sound, due to the belt slip or clutch slip, electromagnetic coil clamp improperly installed and other reasons caused by the clutch abnormal sound, resulting in electromagnetic clutch damage;

2, The electromagnetic clutch is not engaged, which may be caused by too large air gap, poor line contact, and short circuit or break of the electromagnetic coil;

3, the electromagnetic clutch is not separated, it may be that the air gap is not suitable, the clamp ring is not installed or the installation position is improper, the electromagnetic clutch will not be separated and damaged.

What happens when the solenoid valve is broken

After the car air conditioning solenoid valve is broken, it will lead to the normal use of the vehicle's air conditioning, greatly affecting the comfort of the vehicle, although the component does not affect the overall driving safety of the vehicle, but the summer so hot weather in the car driving vehicles, the use of air conditioning is a great impact, once the fault occurs, it is best to carry out maintenance in time is the correct approach.

In order to ensure the uninterrupted operation of the electromagnetic clutch, it must be frequently maintained and maintained:

1, often add lubricant in the moving part of the electromagnetic clutch;

2, regularly check the length of armature stroke. Because in the running process of the clutch, due to the wear of the cutting surface, the travel length of the armature will increase. When the armature travel length does not reach the normal value, it must be adjusted to restore the minimum gap between the brake surface and the turntable. If the armature stroke length increases to the normal value, the suction force may be greatly reduced.

3, if the worn brake surface is replaced, the minimum gap between the brake surface and the turntable should be properly adjusted;

4, often check the tightening degree of bolts, especially tighten the bolts of the electromagnet, the bolts of the electromagnet and the shell, the bolts of the magnetic yoke, the bolts of the electromagnet coil and the wiring bolts;

5, regularly check the mechanical wear of the moving parts, and remove the dust and dirt on the surface of the electromagnet parts.
