本文摘译自 Design News/5-4-81,论述了振动监测方面几个问题,对正在从事机械故碍诊断工作的技术人员有参考意义。一、被监测机器的类型研究这个问题的主要目的是为选择振动监测系统。例如一台内燃机承受强烈的冲击力,正常的振动测量方法却不能被应用(这方面作过少量的研究,尽管操作过程中的问题能被探测,但是,看来振动测量还不能对它提供有效的预防作用).此外,燃气轮机的机壳重量和转子重量之比具有二种情况:很高或很低.例如涡轮气体压缩机,它就具有较重的机壳和高
This article is an excerpt from Design News / 5-4-81, which discusses some of the issues in vibration monitoring and is of reference to technicians who are working on the diagnosis of mechanical problems. First, the type of machine to be monitored The main purpose of this issue is to select the vibration monitoring system. For example, an internal combustion engine is subject to strong impact and normal vibration measurement methods can not be applied (a small amount of research has been done in this respect. Although the problems in operation can be detected, it seems that the vibration measurement does not provide an effective In addition, the ratio between the casing weight and the rotor weight of a gas turbine has two types: high or low, such as a turbo-gas compressor, which has a heavy casing and a high
