铁谱定量分析能获得齿轮箱运行过程中的磨损量,主要指标为大磨粒读数DL和磨损烈度指数IS,并可将这两者绘制成趋势曲线。结合设备自身的故障率及铁谱数据的特点,对铁谱数据进行残差分析筛选合适数据,并改进传统的绝对值公式,计算出能反映齿轮箱运行情况的磨损状态界限值。在实际运用中,改进公式满足设备磨损状态的判断需求,及时反映齿轮箱当前运行状态的磨损情况,为设备故障预防的监测提供了一种方法。
The quantitative analysis of ferrograph can obtain the wear amount during gearbox operation. The main indexes are the large grit reading DL and the wear intensity index IS, and the two can be plotted as the trend curve. Combined with the failure rate of the equipment itself and the characteristics of the iron spectrum data, residual data of the iron spectrum were screened for suitable data and the traditional absolute value formula was improved to calculate the wear status threshold which can reflect the operation of the gearbox. In practical application, improving the formula to meet the equipment wear status of the judgment needs, and timely reflection of the gear box current operating conditions of the wear and tear, equipment failure prevention monitoring provides a way.
