抽油机减速器常见故障诊断

抽油机减速器在现场运转过程中，常因外部工作环境和内部一些因素的制约，出现漏油、齿轮损坏、串轴和轴承损坏等现象。这里通过对这些问题的分析和研究，提出了一些处理方案，并运用频谱分析法对减速器振动信号进行监测，判断减速器零部件早期损坏引起的非正常运行，避免减速器的突然失效，为现场修复减速器、寻找故障原因提供理论依据。

Common faults diagnosis of pumping unit reducer

During the operation of a pumping unit reducer, such troubles as oil leakage, gear damage, shaft leaping and bearing damage always occur due to the affection of the working conditions and the limitation of some of the internal factors. Based on the analysis and research of these troubles, some handle schemes of the reducer are put forward. Moreover, utilize the spectrum analysis to monitor to the reducer vibration signal. Judge early phase in jures of the reducer components, which cause the non- normal operation, and avert the abrupt failure of the reducer. And these provide a basis for on - site trouble shooting and repairing of pumping unit reducer.
