Hydraulic oil filter has the following characteristics:
1. Strength requirements
The hydraulic oil filter element needs to have sufficient strength to withstand pressure difference, installation external force and pressure difference alternating load to ensure integrity and durability during work.
2. Oil smoothness of hydraulic oil filter
The filter element should ensure the smooth flow of oil and have good flow resistance characteristics to ensure the working efficiency of the hydraulic system.
3. High temperature resistance
The hydraulic oil filter element needs to be able to withstand a certain high temperature and be compatible with the working medium to adapt to the needs of different working conditions.
4. Stability of filter layer
The filter layer fiber of the filter element can not be displaced and shed, which is related to the stability and filtration effect of the filter element.
5. Dirt carrying capacity of hydraulic oil filter
The hydraulic oil filter needs to have enough capacity to carry more dirt to maintain the clean and stable operation of the hydraulic system.
6. Various materials of hydraulic oil filter
The hydraulic oil filter element usually uses stainless steel braided mesh, sintered mesh, iron woven mesh and other materials, as well as glass fiber filter paper, chemical fiber filter paper, wood pulp filter paper and other filter materials, the selection of these materials makes the filter element has a high heart rate, large pressure, good straightness and other characteristics.
7. Filtration accuracy of hydraulic oil filter
According to different conditions of use and uses, the number of layers of the hydraulic oil filter element and the mesh number of the mesh will be different to meet different filtration accuracy requirements.
8. Classification of installation positions
According to the installation position of the hydraulic oil filter in the hydraulic system, the hydraulic oil filter is divided into suction oil filter, pressure oil filter and return oil filter, and each undertakes different filtration tasks.
