In this regard, the technical staff suggested that during the installation of the equipment, if the impurities are not strictly controlled and the lubrication is insufficient after a period of time, the compressor may produce abnormal sounds. Fault phenomenon 7: The compressor can run, but the pressure difference cannot be established, accompanied by abnormal sound or blocked after a period of operation, and the cross slip ring breaks, there are many silver metal chips and copper chips inside. When the system has insufficient oil return or insufficient lubrication, abrasion is likely to occur.

It is understood that the life of scroll compressors is generally more than 20 years, but the premise is that users need to do regular maintenance and maintenance work. It is reported that this situation is excessive moisture, the main reason is that the vacuum degree of the refrigeration system is insufficient or the refrigerant moisture content exceeds the standard, it is necessary to supplement the vacuum degree of the refrigeration system or control the refrigerant moisture content. Fault 5: Noisy.

The reason for this situation is generally due to insufficient oil return to the system or high temperature disposable self destruction syringe factory of the compressor resulting in low oil viscosity or excessive refrigerant volume resulting in low oil viscosity. Fault phenomenon four: The air conditioner is turned on when the power is turned on, the measured resistance value is abnormal, and the circuit is shorted to ground. Why does this phenomenon occur? The technical staff said that it is generally due to poor ventilation of the external machine, leakage or shortage of refrigerant, four-way valve series gas, system filter or electronic expansion valve plugging. Copper plating causes the gap to decrease and the friction to increase. Failure phenomenon one: the surface of the mechanism is lightly plated with copper, and heavy with rust.

So, what are the common faults and causes of scroll compressors? Some factory technicians made a simple answer to this. In addition, when some minor faults occur, the user needs to timely determine the cause and do the corresponding treatment to prevent further damage to the equipment. It has small size, light weight, low noise, high reliability, good safety and long life The advantages such as long-term, can replace the traditional medium and small reciprocating compressors in a large range, it can be seen in the pharmaceutical, food and other industries.. The noise outside the factory may occur after the compressor is replaced.
