【JINGTONG HYDRAUMATIC】——The influence of the filter back pressure on the hydraulic system and the answer

The influence of the back pressure of the return oil filter on the hydraulic system.

Problem description: The original system used bypass filtration, but now has become return oil filtration, with all the return oil in the hydraulic system passing through the filter. The back pressure generated by the filter is about 4 bar. What impact will have on the hydraulic system? The system mainly consists of hydraulic motors, cylinders, and control valves. What will happen if the filter becomes blocked? Self-sealing magnetic suction filter.

In my opinion, the back pressure of 4 bar from the return oil will have a negligible impact on the system. If the filter becomes blocked, it' hard to say what the consequences will be. It depends on the specific situation of your hydraulic system. However, it's very difficult for the filter to become blocked, because filter element should be regularly checked. Moreover, there usually aren't that many foreign objects in a typical hydraulic system.

The influence of the back pressure of the return oil on the hydraulic system has been answered up to this point.
