What happens if the refrigerant recovery time of the air-conditioning compressor is too long

What happens if the refrigerant recovery time of the air-conditioning compressor is too long At ordinary times, we will need to simply disassemble and assemble the compressor due to certain circumstances. However, if you do not pay attention to certain matters when disassembling, it will cause the compressor to be directly damaged, so you will not be able to compensate for it. For example, when disassembling the compressor, the refrigerant recovery time should not be too long. As for why? Let’s take a look. 　　Because of the long time of refrigerant recovery, the temperature of the exhaust gas will be very high due to the extremely thin refrigerant gas sucked in, causing the temperature of the pump body of the compressor to rise rapidly. Although, each part of the pump body is generally cast iron or powder metallurgy material. However, there is still a certain difference in the thermal expansion coefficient of each part. Excessively high temperature makes the expansion degree of each part too large. As a result, the fit gap of some parts becomes smaller or even disappears. Eventually, the surface of some related products is abnormally scratched or worn. Causes noise to increase. 　　All in all, we must not let the compressor's refrigerant recovery time be too long, which will do no harm to the compressor, and I hope everyone can pay attention to it!
