Hydraulic filter element
The hydraulic filter element is used in the hydraulic system to filter out the particles and rubber impurities in the system to ensure the cleanliness of the hydraulic system.
Features
1. It is divided into high pressure section, medium pressure section, oil return section and oil suction section
2. It is divided into high, medium and low precision grades. 2-5um is high precision, 10-15um is medium precision, 15-25um is low precision.
3. In order to compress the dimensions of the finished filter element and increase the filtering area, the filter layer is generally folded into a corrugated shape, and the pleating height of the hydraulic filter element is generally below 20mm.
4. The pressure difference of hydraulic filter element is generally 0.35-0.4MPa, but some special filter elements are required to withstand high pressure difference, and the highest requirement is to withstand 32MPa, or even 42MPa equivalent to the system pressure.
5. The maximum withstand temperature, some require up to 135 ℃
product requirement
1. Strength requirements, production integrity requirements, withstand pressure difference, bear installation external force, bear pressure difference alternating load
2. Requirements for smoothness of oil passage and flow resistance characteristics
3. Resistant to a certain high temperature, compatible with the working medium
4. The fibers of the filter layer cannot be displaced and fallen off
5, to carry more dirt
6. Normal use in high altitude and cold areas
7. Fatigue resistance, fatigue strength under alternating flow
8. The cleanliness of the filter element itself must meet the standard
