Pressure Rinsing

What Is the Principle of Pressure Rinsing in Technical Cleanliness Testing, and When Is It Used?   Overview Pressure rinsing is one of the commonly used particle extraction methods in technical cleanliness testing. It uses a cleaning liquid delivered at a controlled pressure and flow rate to rinse component surfaces and internal passages, channels, and cavities that can be effectively reached by the liquid flow. This process dislodges adhering or trapped particles and carries them into the extraction liquid. The liquid is then filtered, and the collected particles are analyzed to evaluate component cleanliness. This method is particularly suitable for valve bodies, pump housings, hydraulic components, pipelines, liquid cooling components, and other parts with deep holes, blind holes,...
