Advantages and disadvantages of hermetic compressor

hermetioally sealed refrigerant compressor

Advantages: The compressor and the motor are housed in a casing that is welded or brazed, and they share the same main shaft, which not only eliminates the shaft sealing device, but also greatly reduces and reduces the size and weight of the entire compressor. Only the suction and exhaust pipes, process pipes and other necessary pipes (such as spray pipes), input power terminals and compressor brackets are exposed on the exterior of the cabinet.

The hermetic compressor and the motor are installed together in a closed casing, and the weld at the joint of the upper and lower casings is a hermetic compressor. The fully-enclosed compressor and the electric motor are equipped with a common main shaft installed in the casing, so the shaft sealing device can be omitted, reducing the possibility of leakage.

The disadvantage is that it is not easy to open and repair: because the entire compressor motor is installed in a sealed casing that cannot be disassembled, it is not easy to open for internal repairs, so this type of compressor is required to have high reliability and long life, and the entire refrigeration The installation requirements of the system are also high. This fully enclosed structure is generally used in small-scale refrigeration compressors for mass production.

The compressor can be divided into open type, semi-closed type and fully enclosed type

With the advancement of science and technology, new air-conditioning systems continue to appear, which has promoted the continuous progress of refrigeration compressor manufacturing technology. From the current development trend of refrigeration compressors, the characteristics of compact structure, high efficiency and energy saving, and low vibration and low noise are the goals that air conditioning compressor manufacturing technology is constantly pursuing. "Yuefeng" brand fully enclosed refrigeration compressors have excellent performance, compact structure, few parts, and long working life. They are widely used in room air conditioners, refrigeration appliances, automotive air conditioners and compressed gas devices.
