What causes the deformation of the hydraulic oil filter？

The hydraulic filter element is used in the hydraulic system to filter out particles and rubber impurities in the system to ensure the cleanliness of the hydraulic system. It can be seen that the hydraulic filter element is a particularly important link in the hydraulic system.

Under normal operation of the hydraulic system, the hydraulic filter element sometimes deforms. Generally speaking, the deformation is largely caused by the overloaded working state of the hydraulic filter element. For example, hydraulic excavators generally need to replace the hydraulic oil after 2000 hours of operation. , otherwise it will cause system pollution and system failure.

It can be seen that the replacement cycle of the hydraulic oil filter element is generally determined by the working hours, the replacement of the hydraulic oil return filter element is every 250 hours, and the follow-up is about 500 hours of working hours.

If the pressure difference of the hydraulic filter element is too high for a long time, the central pipe will be crushed and the filter element will be deformed, which will cause the hydraulic system to work normally. If the pressure difference is always too high, the filtering effect will also be abnormal.

The hydraulic filter element has been working for too long and not replaced in time is the main cause of deformation. Failure to maintain it according to the specified time will cause damage to the hydraulic filter element, so we must pay more attention to it during use.
