![]() ![]() Next, we will explain to you the solution to the reverse rotation of the compressor after the car is stopped. Most compressor faults can be troubleshot, but because the number of compressor parts are small, and it requires high assembly accuracy requirements, special tools and fixtures are needed. The common faults of the general compressor are plugging, leakage, refrigeration failure and abnormal noise. Most of the moving parts of the automobile air conditioning system are on the compressor, so the compressor requires much maintenance. The compressor of the car is in the air conditioner unit that is essential. We recommend that you use a relay that can sense instantaneous power outages, so that the device can lock the compressor for two minutes before allowing it to restart. This has no effect on the compressor, which restarts and runs in the correct direction after the motor protector is reset. The compressor will continue to rotate in a reverse direction for several minutes after being powered, until the compressor motor protector operates. It means that the power failure time is less than 0.5 seconds, which may cause the rotation direction of the single-phase compressor to change. There is a situation that will lead to the reverse rotation of the refrigeration compressor, which is the instantaneous power failure. Generally speaking, the scroll compressor only needs to be replaced with any phase of the three-phase line. However, long periods of reverse rotation damage refrigeration compressors, and equipment manufacturers can set up phase sequence protection modules in the control loop to ensure that the compressor does not run in the case of the wrong phase sequence. In addition, if the compressor is in reverse rotation, the noise of the compressor is abnormal, and the running current is obviously lower than normal. ![]() When installed in the field, the refrigeration compressor can be determined to be rotating in the correct direction by the decrease of the suction pressure and the increase of the exhaust pressure. The direction of rotation of the three-phase compressor is determined by the phase sequence of the power supply, so there is a chance that the compressor will rotate reversely. Single-phase compressors always start and run in the correct direction, except in the case of instantaneous power failure. Scroll refrigeration compressors can only compress in one direction of rotation. ![]() First of all, we should make it clear that the reverse rotation of the compressor is adverse. As we know, the operation of the internal compression structure of the refrigeration compressor has a fixed direction. ![]()
