Description

Technical Field

[0001] The invention relates to the field of refrigeration compressors, and in particular to a built-in vibration self-testing device for refrigeration compressors. Background Art

[0002] In the refrigeration system, the refrigeration compressor is the core equipment, and its performance and stability 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 equipment, the stable operation of the refrigeration compressor is crucial. However, in the actual operation process, the vibration problem of the refrigeration compressor has always been a key factor that plagues the development of the industry.

[0003] On the one hand, when the refrigeration compressor is running, the complex internal mechanical structure interacts with each other and generates 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 loosen the connecting parts, resulting in a decrease in the matching accuracy between the parts, which in turn affects the overall performance of the compressor; long-term vibration may also cause fatigue damage or even breakage of some precision parts, greatly shortening the service life of the compressor and increasing the maintenance cost and downtime of the equipment. On the other hand, excessive vibration will also reduce the refrigeration effect. Vibration will interfere with the normal flow of refrigerant in the system, affect the heat exchange efficiency, and make the refrigeration system unable to reach the expected refrigeration temperature and unable to meet actual use needs.

[0004] At present, there are many deficiencies in the monitoring and control of refrigeration compressor vibration. Most of the existing detection methods rely on external monitoring equipment, which can only roughly judge the operating status of the compressor as a whole, and it is difficult to accurately obtain detailed information on the internal vibration. Since it is impossible to deeply understand the vibration conditions of specific internal components, it is difficult to take effective vibration reduction measures in a targeted manner. In addition, the installation and debugging of external monitoring equipment is relatively complicated, requiring additional space and professional technicians to operate, which not only increases costs, but may also lead to inaccurate monitoring results due to restrictions on installation location and method.

[0005] In terms of equipment maintenance, due to the lack of effective monitoring of internal vibration, maintenance personnel can only perform inspections and repairs after a fault occurs. This passive maintenance method is not only inefficient, but may also cause more serious equipment damage due to delayed maintenance. Moreover, during the maintenance process, since it is difficult to accurately determine the source of vibration, the maintenance work is also somewhat blind, further increasing the difficulty and cost of maintenance.
