Information
Whether the filter element is qualified or not is subject to strict test. Each test has its own industry standard acceptance standard. Only after a series of tests can it be rated as a high-quality product. Please pay attention to the purchase, as far as possible after the performance test products.
1. Filtration accuracy:
According to the needs of the hydraulic system to determine the cleanliness level of stains, according to the cleanliness level according to the attached table to select the filter precision. When evaluating the main standard of hydraulic oil filter element The beta value measured by iso4527-1981e (multiple experiments) refers to the ratio of the number of particles on both sides of the inlet and outlet of the oil filter when the oil mixed with standard experimental powder passes through the oil filter for several times. 
2. Flow characteristics:
The flow rate and pressure drop of the oil are important parameters of the flow rate characteristic. The flow rate characteristic experiment is conducted according to iso3968-91 standard to draw the flow-pressure drop characteristic curve.
Under the rated oil supply pressure, the total pressure drop (the sum of the pressure drop of the filter shell and the filter element) should generally be less than 0.2Mpa.
3. Filter element strength:
The rupture - shock resistance test should be carried out according to iso2941-83 standard, and the pressure difference that drops sharply when the filter element is damaged should be greater than the specified value.
4. Flow fatigue characteristics:
The fatigue test of 100,000 cycles should be carried out according to iso3724-90 standard.
Filter element products of Hengshui Yinbeier are all high quality products with performance indexes mentioned above. Please feel free to purchase.
