Shallow oil return method of parallel refrigeration compressors

Compressor oil return is one of the key problems in piping design, and it is also a troublesome problem that must be solved; the solubility of refrigerant and lubricating oil should be miscible, slightly soluble, and miscible at high pressure and separate at low pressure. ; The problem of oil return often occurs in the exhaust pipe and return pipe. Today, the analysis is the oil return problem of parallel compressors

Common faults and causes of compressors

Common faults and causes of compressors Common compressor failures are as follows: 　　L. The compressor cannot start normally 　　 The power supply voltage is too low, the motor circuit is poorly connected, or the exhaust valve is leaking, resulting in too high pressure in the crankcase. The energy regulation mechanism has failed.

Analysis of the reason why cold storage should not be built underground

Many people think that building cold storage underground will have better thermal insulation effect than cold storage on the ground, because in the past, when the technology was backward, it was very common to choose cellars as crop storage. But from a commercial point of view, it is not scientific to blindly build the cold storage underground. The cold storage construction team stands from the perspective of consideration for customers
