The progress of science and technology and the continuous emergence of new air-conditioning systems have promoted the continuous progress of the manufacturing technology of high-pressure compression mechanism chillers. According to the current development trend of high-pressure compressor refrigeration, the characteristics of compact structure, high efficiency and energy saving, low vibration and low noise are the continuous goals of high-pressure compressor refrigeration manufacturing technology.

The compressor has important uses, and the stability and continuity of its working state directly affect the production efficiency of the enterprise. Therefore, it is necessary to ensure the normal operation of the compressed air pipeline in Dalian, and timely judge and deal with the common faults. At the same time, it is also necessary to strengthen the maintenance and management of the compressed air pipeline in Dalian, so as to avoid the abnormal operation state of the air compressor and even the occurrence of major safety accidents.

Relevant operators of Dalian compressed air pipeline shall carry out all-round inspection and detection before equipment operation, which is the basic step to ensure the normal and stable operation of the air compressor. They shall strive to do a good job in daily maintenance and make a comprehensive inspection. They shall formulate detailed and comprehensive daily maintenance rules and regulations, establish and improve the supervision mechanism, and strive to improve their own skills and comprehensive quality level.

The gas is liquefied by compression, cooling and expansion, and is used for artificial refrigeration (refrigeration and air conditioning, etc.) such as ammonia or Freon compressors. Its compression pressure is mostly 8-12 kg / cm2. This type of compressor is usually called "refrigerator" or "ice machine". In addition, if the liquefied gas is a mixed gas, it can be packed separately.
