What accidents may occur during the operation of hydraulic oil filter cartridges?

When using hydraulic oil filters for work, unlike water filters, hydraulic oil filters may experience suction and collapse during application. What is the reason for this? How was it caused?

In fact, the direct cause of hydraulic oil filter suction is the formation of internal negative pressure.

The check valve plate in the hydraulic oil filter equipment can help operators avoid the backflow of oil to the bottom shell, thereby greatly avoiding the occurrence of insufficient lubricating oil when the equipment is restarted.

This largely ensures the smooth filtration of the equipment filter element, preventing the filter element from bursting and causing suction problems.

From this, it can be concluded that once there is a problem with the check valve plate in the hydraulic oil filter element, such as loose closure, aging failure, etc., it will cause the oil to flow back;

If the surrounding temperature is low and the equipment is shut down for a long time without operation, the oil inside the equipment may be sucked dry, resulting in a negative pressure environment and causing the equipment to collapse.

Therefore, once the check valve plate is found to be abnormal, it should be replaced in a timely manner to avoid a series of unnecessary losses.

How to properly clean the hydraulic oil filter element?

In real life, many people find it difficult not to clean the hydraulic oil filter element, which will greatly reduce the service life of the hydraulic oil filter element. In fact, there is a method to clean the hydraulic oil filter element. The original liquid pressure oil filter element is generally made of stainless steel wire mesh. Cleaning such hydraulic oil filter elements requires soaking the filter elements in kerosene for a period of time. When removing the filter element, it is easy to blow away stains with air. However, it should be noted that if the original hydraulic oil filter element is not too dirty, this method cannot be applied and a new hydraulic oil filter element still needs to be replaced.

The loss of the filter element is mainly caused by the blockage of pollutants on the filter element. The process of loading pollutants into the filter element is the process of blocking the through hole of the filter element. When the filter element is blocked by contaminated particles, it can reduce the pores for liquid flow. In order to ensure the flow rate of the filtering material, the pressure difference will increase. In the initial stage, due to the many holes on the filter element, the pressure difference through the filter element increases very slowly, and the blocked holes have little impact on the overall pressure loss. However, when the blocking hole reaches a certain value, the blocking is very fast, and at this time, the pressure difference through the filter element rises very quickly.

The differences in the number, size, shape, and distribution of holes in standard filter cartridges also explain why one filter cartridge has a longer lifespan than another. For filter media with a certain thickness and standard filtration accuracy, the pore size of filter paper is smaller than that of glass fiber filter media, so the clogging speed of filter paper filter media is faster than that of glass fiber filter media. Multilayer fiberglass filter media contains a significant amount of pollutants. When the liquid flows through the filter medium, particles of different sizes are filtered by each filter layer. The small holes in the post filter medium will not be blocked by large particles. The small pores in the post filtration medium will still filter out a large number of small particles in the fluid.
