Hydraulic fluid power — Particulate contamination analysis — Extraction of fluid samples from lines of an operating system 液压流体动力——颗粒物污染分析——从操作系统的管路中提取流体样本

发布日期： 1992-10-21

优选的方法是从主流线中提取流体样品，以使样品中的颗粒污染物代表取样点处流动的流体。另一种方法是从储液罐中提取样品，但只有在未安装合适的取样器的情况下，才应使用这种方法。

The preferred method is to extract fluid samples from a main flowline in such a manner that the particulate contaminant in the sample is representative of the fluid flowing at the point of sampling. An alternative method is to extract a sample from the reservoir, but this method should only be used if a suitable sampler is not fitted.
