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.

How to use empirical methods to inspect rolling bearings

How to use empirical methods to inspect rolling bearings Some operators lack the experience in identifying rolling bearings and continue to use them as long as they see no obvious damage to the rolling bearings, causing serious failures later. Some people only need to remove the rolling bearings and replace them without inspection.
