1. Shaking shabu-shabu method: Inject a certain amount of clean test liquid into the component and seal the component, shake the component strongly by mechanical methods to flush all the pollutants inside the component into the test liquid, and then measure the contamination level of the test liquid. 2.
2, the test bench flushing method will be connected to the pre-purified components of the test bench system, so that the test liquid cycle through the components, the components of all the pollutants inside the test liquid flushed to the test liquid, and then from the system to collect samples for the determination of contamination.
3,Dismantling and rinsing method After the external components are thoroughly cleaned, the components are disassembled, and the wet area of the parts is carefully rinsed with detergent, and then all the solvents are collected and the degree of contamination is measured.
Shaking shabu-shabu method is a simple and easy to implement component cleanliness testing method, mainly applicable to static components, such as conduits, pipe fittings, hoses, filters, shells and tanks, etc.; test bench flushing method is mainly used to test the cleanliness of dynamic components, such as hydraulic pumps, hydraulic motors, hydraulic cylinders and a variety of hydraulic valves and so on.
In addition, if the component assembly after the cleaning process and component cleanliness test combined, can effectively control the cleanliness of the component, and simplify the test process. When the components have been cleaned and meet the specified cleanliness requirements, components and systems can be considered as a whole and have the same level of contamination. In this way, the measured fluid contamination of the system is also the cleanliness of the component, without the need for volume conversion.
