Description

Technical Field

[0001] The present invention relates to the field of refrigeration compressors, and particularly to an in-built vibration self-checking device for a refrigeration compressor. Background Art

[0002] In a refrigeration system, as a core device, the performance and stability of a refrigeration compressor directly determine the operation effect of the entire refrigeration system. In various refrigeration application scenarios, such as household air conditioners, commercial refrigeration equipment, and industrial refrigeration devices, etc., the stable operation of the refrigeration compressor is crucial. However, during the actual operation process, the vibration problem of the refrigeration compressor has always been a key factor plaguing the development of the industry.

[0003] On the one hand, when the refrigeration compressor is running, the complex internal mechanical structures interact with each other to generate vibration. When the vibration frequency is too high, this continuous vibration will have a serious impact on the components inside the compressor. For example, it will cause the connecting components to become loose, resulting in a decrease in the fitting accuracy between the components, thereby affecting the overall performance of the compressor; long-term vibration may also cause some precision components to suffer from fatigue damage or even fracture, greatly shortening the service life of the compressor and increasing the equipment maintenance cost and downtime. On the other hand, excessive vibration will also reduce the refrigeration effect. Vibration will interfere with the normal flow of the refrigerant in the system, affect the heat exchange efficiency, making the refrigeration system unable to reach the expected refrigeration temperature and unable to meet the actual use requirements.

[0004] Currently, there are many deficiencies in the monitoring and control means for the vibration of refrigeration compressors. Most of the existing detection methods rely on external monitoring devices, and these devices can often only roughly judge the operation state of the compressor as a whole, and it is difficult to accurately obtain the detailed information of the internal vibration. Since it is impossible to deeply understand the vibration situation of specific internal components, it is also difficult to take effective vibration reduction measures targeted. In addition, the installation and debugging of external monitoring devices are relatively complex, requiring additional space and professional technical personnel to operate, which not only increases the cost, but also may lead to inaccurate monitoring results due to the limitations of the installation position and method.

[0005] In terms of equipment maintenance, due to the lack of effective monitoring of internal vibration, maintenance personnel often can only conduct inspections and repairs after a failure occurs. This passive maintenance method is not only inefficient, but also may cause more serious equipment damage due to delayed repairs. Moreover, during the repair process, due to the difficulty in accurately judging the vibration source, the repair work also has a certain degree of blindness, further increasing the repair difficulty and cost.
