How to judge the quality of engineering machinery filter cartridges?

Release time:

Apr 14,2023

In the process of using and managing engineering machinery filter elements, it always causes a problem for everyone, whether the filter element should be replaced or not. How to judge the quality of the filter element?
Many users may think that the bypass valve of the hydraulic oil filter and the safety valve of the system have the same function: after the hydraulic oil filter element is blocked, the bypass valve opens, and the full flow of system turbid liquid passes through, which has an impact on the system, which is a misconception. When the bypass valve of the filter is opened, the precision filter element quotes, and pollutants blocked by the filter element will re-enter the system through the bypass valve. At this time, the pollution concentration of local oil and the precision filter element will greatly damage the hydraulic components, and the previous pollution control will also lose its significance. Unless the system requires very high continuity of operation, choose engineering machinery filter elements without bypass valves. Even if a filter with a bypass valve is used, precision filter installation services require timely cleaning or replacement of the filter element when the filter is contaminated and blocked, which is the way to ensure the safe and reliable operation of the system. In fact, when the filter element is found to be clogged and an alarm is triggered, it indicates that the filter element needs to be replaced. Persisting in not replacing will cause certain damage to the equipment. If possible, it is recommended to replace it immediately.
How to judge the quality of engineering machinery filter cartridges?
Many users, without oil pollution detection equipment and precision filter processing, judge the performance of filters based on their service life. The speed of clogging the filter indicates its good or bad performance, while the concept of precision filter elements is one-sided. Because the filtration performance of filters is mainly reflected by performance indicators such as filtration ratio, pollutant capacity, and original pressure loss, precision filter elements can only have a longer service life under the same working conditions and hydraulic system cleanliness requirements.
Some users also believe that the more precise the accuracy, the better the quality. Of course, this idea is also one-sided. The precision of the filter element is too precise, and of course, the filtering and blocking effect is relatively good. However, it will also cause the flow rate to not meet the requirements, and the filter element will be blocked quickly. So the precision of engineering machinery filter cartridges is suitable for work and use, which is of good quality.
