Correct understanding of the use of filter element

Correct understanding of the use of filter element The filter with bypass valve can not be cleaned for a long time after the filter element is blocked Because after the filter element is blocked, the bypass valve is opened, and the system oil flows through. The pollutants blocked by the filter element (the contaminated particles that have been filtered out) will re-enter the system through the bypass valve. At this time, the local oil pollution concentration is the highest, causing great damage to the hydraulic components, and the previous pollution control will lose its significance. Unless the system requires very high continuity of operation, it is better to choose a filter without bypass valve. Even if the filter with bypass valve is selected, the filter element should be cleaned or replaced in time when the transmitter is blocked by the filter pollution, so as to ensure the safe and reliable operation of the system. Relationship between service life of filter and performance of filter. Because many users do not have oil pollution detection equipment, they judge the performance of the filter by the service life of the filter. The blocking speed of the filter indicates the good or bad performance of the filter. These two concepts are one-sided. Because the filtration performance of the filter is mainly reflected by filtration ratio, contaminant capacity, original pressure loss and other performance indicators, only under the same working conditions and ensuring the cleanliness requirements of the hydraulic system, the longer the service life, the better.
