液压传动 颗粒污染分析 从工作系统管路中提取油样

[中文适用范围]： 优选的方法是从主流管中提取流体样品，使得样品中的颗粒污染物代表在采样点流动的流体。 另一种方法是从储层中提取样品，但只有在没有安装合适的采样器时才应使用此方法。 [外文原描述]： 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.
