约克离心式冷水机组自投入运行以来已有15年,该机组具有制冷量大、效率高、安全可靠等优点,但随着使用年限的增加,在平时的运行过程中也会出现一些故障,其中油温控制失灵就是一个比较常见的问题。本文将对此问题展开分析,并提出相应的改进措施。离心式压缩机一般需要增速齿轮来放大主动轴转速,约克采用的是一对斜齿轮为压缩机提供动力,这样的设计
York Centrifugal chillers have been in operation for 15 years since they were put into operation. The chillers have the advantages of large cooling capacity, high efficiency, safety and reliability. However, with the increase of their service life, some faults occur during normal operation. Failure to control the oil temperature is a more common problem. This article will analyze this issue and propose appropriate improvements. Centrifugal compressors generally require a speed increasing gear to amplify the speed of the drive shaft. York uses a pair of helical gears to power the compressor. Such a design
