Description
技术领域Technical field

背景技术Background technique
近年来冷水机越来越多地在工业生产中进行使用，冷水机是为了保证精密仪器在恒温的条件下进行工作的设备，这些高精密、高能量密度的仪器在加工过程中会产生大量的热量，如果不及时进行降温，会导致仪器过热受损，而有了冷水机的保护，可以使其在恒温的状态下加工。In recent years, chillers are increasingly used in industrial production. Chillers are equipment used to ensure that precision instruments work under constant temperature conditions. These high-precision, high-energy-density instruments will produce a large amount of energy during processing. If the heat is not cooled down in time, it will cause overheating and damage to the instrument. However, with the protection of the chiller, it can be processed at a constant temperature.
目前，市场上的冷水机大多采用螺栓配合避震脚垫和限位套的方式来固定压缩机，并达到保护压缩机的作用，而制冷管路主要通过增加各个管路的折弯数量来减少压缩机振动带来的影响。当制冷系统比较复杂时，例如复叠式制冷系统，零件数量多，相应的制冷管路数量也多，设备内有限的空间导致部分管路不能设计多个折弯，特别是与压缩机进出口相连的管路，如果减震设计有缺陷，冷水机的系统可靠性就存在风险。At present, most chillers on the market use bolts, shock-absorbing foot pads and limit sleeves to fix the compressor and protect the compressor. The refrigeration pipelines are mainly reduced by increasing the number of bends in each pipeline. Effects of compressor vibration. When the refrigeration system is relatively complex, such as a stacked refrigeration system, there are a large number of parts and a corresponding number of refrigeration pipelines. The limited space within the equipment means that some pipelines cannot be designed with multiple bends, especially with the compressor inlet and outlet. If the shock absorption design of the connected pipelines is defective, the system reliability of the chiller will be at risk.
