Description:
The three main parts of the compressor clutch assembly are the coil magnet, the pulley, and the clutch plate. The clutch drive plate is splined to the input shaft of the compressor.
The compressor clutch is a large electromagnet that, when energized, draws the clutch plate into the clutch pulley. The magnetic field holds the clutch plate tightly against the clutch pulley as long as current is supplied to it. This in turn engages the drive pulley to the compressor input shaft, causing the shaft to spin. When the compressor clutch is not engaged, the input shaft of the compressor does not spin and the drive pulley freewheels on a sealed bearing assembly.
Installation:
1. It should be ensured that the clutch is faulty. For example, check if the power supply circuit is working normally.
If the power supply circuit works normally, the clutch does not pull in. This situation needs to be replaced.
2. Remove the compressor, remove the old electromagnetic clutch, check the compressor for damage,
and clean the front cover and coil contact surface of the compressor without confirming that the compressor is not faulty.
3. Install a new coil and secure it with a screw or shaft with a circlip.
4. Install the pulley and fix it with the circlip of the shaft. Check if the pulley rotates with the coil and the friction is unqualified. To check the reason.
5. Install the suction cup and adjust it to a reasonable gap between 0.2-0.6MM with the gap pad. After fixing the suction cup, check whether the suction is normal. After the power is off, the rotating pulley is separated from the suction cup.
No friction is qualified.
6. Install the compressor.
