What is the reason for the impurities in the hydraulic oil filter?

The oil return filter element in the hydraulic system, as the name suggests, is the filter element used in the system oil return. After the actuator is worked, due to the wear and tear of the equipment operation, particle impurities and rubber impurities may be generated. If you want to not bring the impurities in the oil into the fuel tank , can only be filtered with a filter element or filter in the oil return system.

Hydraulic oil often contains granular impurities, which will cause wear of the hydraulic components relative to the moving surface, spool valve sticking, and blockage of the throttle orifice, which greatly reduces the reliability of the system. The installation of a certain precision oil filter in the system is to ensure that according to the material and structure of the filter element, the oil filter can be divided into mesh type, line gap type, paper filter element type, sintered oil filter and magnetic oil filter, etc. . According to the different positions of the oil filter, it can also be divided into oil suction filter, pressure filter and oil return oil filter. There are four kinds of filters and special filters, which can filter out impurities larger than 100μm, 10-100μm, 5-10μm and 1-5μm respectively.

Hydraulic oil filter elements are generally used in hydraulic stations and hydraulic systems, and should be cleaned regularly, because after a period of use, the hydraulic oil filter element has been blocked by the stains in the hydraulic oil, thus failing to achieve a certain filtering effect. To ensure that the hydraulic oil filter element prolongs its life, Wannuo filter element teaches you how to clean the hydraulic oil filter element:

Many people think that the hydraulic oil filter element is difficult to clean without cleaning, which will greatly reduce the service life of the hydraulic oil filter element. In fact, there is a way to clean the hydraulic oil filter element. Generally, the original hydraulic oil filter element is made of stainless steel wire mesh. To clean such a hydraulic oil filter element, the filter element needs to be soaked in kerosene for a period of time. stained. 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 should be replaced.

The loss process of the hydraulic oil filter element is mainly the blockage of the filter element by pollutants. The pollutant loading process of a filter element is the process of blocking the through holes of the filter element. When the filter element is blocked by polluted particles, the holes that can pass the liquid flow are reduced, and the pressure difference will increase to ensure the flow through the filter material. In the initial stage, since there are many holes on the hydraulic oil filter element, the pressure difference through the filter element increases very slowly, and the blocked holes have little effect on the overall pressure loss. However, when the plugged hole reaches a value, the plugging is very rapid, at which point the differential pressure across the filter element rises very quickly. The number, size, shape and distribution of the media pores of a hydraulic oil filter element indicate why one filter element lasts longer than another. For a filter material of a given thickness and filtration accuracy, the filter paper has fewer pores than the glass fiber filter material, so the filter element of the filter paper material is blocked faster than the filter element of the glass fiber filter material. The filter element of the multi-layer glass fiber filter material can accommodate more pollutants. When the liquid flows through the filter element, each filter layer filters out particles of different sizes, and the small holes in the filter material of the rear layer will not be blocked by large particles. The small pores of the filter media still filter a large number of small particles in the fluid

The main function of the hydraulic oil filter element is to filter out metal particles, impurities, etc. in the special oil of the hydraulic system, so that the oil entering the main engine is very clean, so as to protect the safe operation of the main engine equipment.
