用多种方法对往复式压缩机进行状态监测

Monitoring the Condition of a Reciprocating Compressor by Various Methods

利用等离子吸收光谱等，对我公司特大型往复式压缩机进行润滑油中的磨粒元素监测，同时利用红外点湿仪对磨擦副进行温度监测。经过一年多来的摸索，已初步找到了一些规律，但是要提高监测水平和故障预报准确率，仍需要继续探索。今后设想用多种方法进行综合监测，在原有基础上再结合铁谱和振动等监测方法。

We have been monitoring the various elements of the wear in the lubricating-oil of the big reciprocating compressor by plasma absorption spectrum etc. In the mean time, we also have been detecting the temperature of the friction pairs by the spot themometer. Over one year s groping, we have fed some regular patterns for the machine faults, but we still need exploring to improve monitoring ability and diagnosis accuracy' From now on, we ton attempting to adopt more than one method, such as ferrograph analysis and low frequency vibration analysis, and the line.
