Characteristics
1, points for high pressure with, medium voltage segment, back in the period of use and oil absorption period of use
2, the low points precision grades. 2-5 um for high precision, 10, 15 um for medium precision, 15-25 um for low precision.
3 for compressed filter product appearance, size, increasing filtering area, general filter layer part converted into corrugated, and hydraulic filter plait altitude generally in 20 mm below
4, hydraulic filter under pressure differential generally in 0.35-0.4 MPa, but individual special filter, requirements under high pressure difference, the highest requirements under 32 MPa, even 42 MPa equivalent system pressure.
5, the highest temperature under, some requirements to 135 dgree
Requirements of the filter
1, the required strength, make a complete degree requirements, withstand the pressure difference, bear installation outside force, bear pressure differential alternating load
2, the smooth degree of oil demand, flow resistance characteristic
3, a high temperature resistance, and working medium compatibility
4, filter layer fiber cannot displacement and fall off
5, carrying more dirt into
6, high altitude and cold areas use normal
7 and fatigue resistance, alternating flow of the fatigue strength
8, filter itself to cleanliness standards
