Trouble analysis and elimination of semi-hermetic compressor motor Abstract:Semi—hermetic compressor often be used in the water—cooling unit of air conditioning system,and it’S motor which work in rather high temperature and pressure condition,even work with refrigerator and oil, has a poor working condition.It will cause some trouble with the motor if the water—cooling unit of the air conditioning system out of operating or mending.However,the motor of water—cooling unit will be destroyed easily after mending. By studying some causing of the motor—trouble in semi—herm etic compressor,it was summarized that the main reasons include that the oil is gotback badly;the three—phase current of the motor is uneven;the water content of refrigeration is large;lack the refrigerator and operate;the vacuum operates;the power is too low in voltage;the ma~er enters compressor,and etc.If you want to prevent the compression—motor of maintenance from trouble soon again,you must solve the reason which produce this trouble, and can’t be brought into the new trouble factor in maintenance.

Refrigerator compressor working principle, wiring diagram, structure
The core component of the refrigerator is the compressor. If there is no compressor with good quality and technology, it is not a good refrigerator. At present, many products on the market advertise the use of high-quality compressors, so which compressor brands are in China, and which failures are prone to occur? I will introduce you one by one in the following!

What is the refrigerator compressor used for
Refrigerators use evaporative cooling or vaporization to absorb heat to achieve the purpose of refrigeration. The throat of the refrigerator is filled with a refrigerant known commercially as Freon, commonly known as refrigerant. A commonly used one is difluorodichloromethane, which is a colorless, odorless and non-toxic gas with a boiling point of 29°C. Freon is pressurized by the compressor when it is in a gas state.
