This document was first published in.1998 and this is the first revision.IntroductionIn a hydraulic system, power is transmitted and controlled by means of pressurized fluid in a closed circuit. The liquid is both a lubricant and a dynamic force transmission medium. The presence of solid particulate contamination in liquids not only hinders the lubricating properties of the liquid, but also causes wear of components. The degree of particle contamination in the liquid is directly related to the performance and reliability of the system, so it needs to be controlled within the allowable range of the system. liquid A pressure filter can be used to control the amount of particulate contamination to suit both the contamination sensitivity of the system and the reliability requirements of the user. Users of hydraulic equipment typically specify maximum particle contamination levels for components, systems, and production processes in sequence. Dyeing is often referred to as Target Cleanliness (RCL for short). Cleanliness is determined by sampling the fluid in the hydraulic system and measuring particle contamination arrive. If the measured particle contamination level is higher than the target cleanliness level, action needs to be taken to re-control it within a reasonable range so that the system cleans Cleanliness returned to normal. To avoid costly unnecessary measures, accurate sampling and measurement of particle contamination is required. The best method for sampling is to take a liquid sample from the main flow line of the working hydraulic system, which is the most representative, that is, the liquid sample. Particulate contamination in is representative of the fluid flowing at this sampling point; an alternate method is to extract the To take liquid samples, this method can only be used when a suitable sampler is not installed on the system pipeline. The extracted liquid samples can be analyzed offline or for online analysis. This document is intended to provide a uniform, consistent procedure for extracting fluid samples from hydraulic systems.
