Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a liquid impact prevention structure of a stator plate of a scroll compressor. Background Art

[0002] A scroll compressor is a type of positive displacement compressor. The compression component consists of a movable scroll and a stationary scroll. The relative revolution of the movable and stationary scrolls forms a continuous change in the closed volume to achieve the purpose of compressing the gas. The gas is sucked into the compression space formed by the movable and stationary scrolls. As the movable scroll moves, a high-pressure area is formed on the stationary scroll. Since there are more oil substances in the scroll compressor, such as cooling oil and lubricating oil, these oil substances will enter the high-pressure area of ​​the stationary scroll. Since the oil substances cannot be compressed, under the action of high pressure, the oil substances will become high-speed oil droplets, thereby damaging or piercing the stationary scroll. This is called liquid hammer.

[0003] At present, the stator of some scroll compressors cannot effectively prevent liquid hammer when in use, resulting in serious damage to the scroll compressor caused by liquid hammer when the stator runs at high speed, greatly affecting the performance and service life of the scroll compressor.

When there are no high-speed oil droplets, the spring 54 will reset, and one end of it will continue to press against the steel ball 56 to block the liquid-proof hole 55 to form a seal to prevent air leakage.
