Our Products

Hydraulic system oil filter element is an important part of the hydraulic system, the following is about it in detail:

1. ** Function **
- ** Filter impurities ** : The oil in the hydraulic system will carry a variety of solid particles in the flow process, such as metal shavings, sand, dust, etc. If these impurities are not filtered out, they will enter the matching gap of the hydraulic components with the oil, which will aggravate the wear of the components and shorten the service life of the components. The oil filter element can effectively filter out these impurities, keep the oil clean, and ensure the normal operation of the hydraulic system.
- ** Protective element ** : As the main oil filter of the hydraulic system, it is not only the main oil filter to ensure its oil pollution, but also through its own efficient purification of the oil, the hydraulic pump plays a good protective role, can prolong the service life of the hydraulic system.
- ** Maintain System performance ** : Clean oil is essential for the proper operation of the hydraulic system. The oil filter element can remove impurities and pollutants in the oil and prevent them from entering the sensitive parts of the system, so as to ensure the normal operation of the hydraulic system and maintain the performance and stability of the system.

2. ** Installation location **
- ** Oil suction pipeline: generally installed in the suction port of the hydraulic pump, the main role is to filter the oil into the hydraulic system, filter out the large impurity particles, to protect the hydraulic pump. The filtration accuracy is generally 100 ~ 180μm, depending on the self-suction ability of the pump to determine, flow resistance is too large to lead to hydraulic pump cavitation.
- ** Pressure line ** : It is installed on the pressure oil line to further filter impurities in the oil and protect the hydraulic pump and downstream hydraulic components. The filtration accuracy is 5-10 μm, the pressure of the filter is large, the vibration is also very good, and the pressure range is determined according to different pressure levels.
- ** Oil return pipeline ** : All kinds of components in the process of work produced by the abrasive particles and other dirt can be set back to the oil return pipeline oil filter and be intercepted, avoid returning to the tank again, again be sucked by the hydraulic pump, to provide indirect filtration for the system. Its accuracy is determined according to the requirements of oil pollution. In addition, it is necessary to consider the impact of oil return hydraulic pressure, and the structure should be strengthened.
- ** Separate filtration system ** : In some large hydraulic systems, a hydraulic pump and oil filter may be set up to form an independent filtration circuit to meet the higher requirements of the system for oil cleanliness.
- ** Bypass or before specific components ** : In some specific hydraulic systems, fine oil filters are also installed separately on the bypass or in front of important components (such as servo valves, precision throttle valves, etc.) to ensure the normal operation of these components.

3. ** Material structure **
- ** Material ** : usually made of stainless steel woven mesh, sintered mesh, iron woven mesh and other metal materials, some also use glass fiber filter paper, chemical fiber filter paper, wood pulp filter paper and other paper materials. Different materials have different filtering accuracy and strength to meet different application requirements.
- ** Structure ** : generally made of single or multi-layer metal mesh and filter material, with high heart rate, high pressure, good straightness, stainless steel material, without any burr, to ensure long service life.

4. ** Select key points **
- ** Filtering accuracy ** : according to the specific requirements of the hydraulic system to select the appropriate filtering accuracy of the oil filter element, to ensure that can effectively filter out the impurities in the oil, while not excessive restrictions on the flow of oil.
- ** Flow capacity ** : It is necessary to maintain sufficient flow capacity for a long time to ensure the normal operation of the hydraulic system. If the flow capacity is insufficient, it will lead to the increase of oil flow resistance and affect the performance of the system.
- ** Strength and corrosion resistance ** : the filter core should have sufficient strength, not damaged by the action of hydraulic pressure; At the same time, it also has good corrosion resistance and can work for a long time under the specified temperature to adapt to different working environments.
- ** Convenience of cleaning or replacement ** : In order to facilitate maintenance and management, oil filter elements that are easy to clean or replace should be selected.

In summary, the hydraulic system oil filter element plays a crucial role in the hydraulic system. It can not only effectively filter impurities and pollutants in the oil, protect the hydraulic components from damage, but also maintain the normal performance and stability of the system.
