"Air Filter Factory Direct" Hydraulic Oil Filter Element Introduction
The hydraulic oil filter element is marked on the manufacturer's product sample, or the nameplate is the nominal filtration accuracy, rather than the absolute filtration accuracy, as long as the beta value measured by the experiment indicates the filtering ability of the filter.we are oil filter wholesale and best oil filter china,you can know it.
The hydraulic oil filter element should also be satisfied with the pressure loss requirement (the total pressure difference of the high pressure filter is less than 0.1PMa, and the total pressure difference of the return filter is less than 0.05MPa) to ensure the flow rate and the filter filter life. optimize.
1. The filtration accuracy is the first. According to the requirements of the hydraulic system, the cleanliness level of the stains is confirmed. According to the cleanliness level, the filtration accuracy of the hydraulic oil filter is selected according to the gauge. The most commonly used hydraulic oil filter element on construction machinery has a nominal filtration clarity of 10 μm.
The nominal filtration accuracy does not truly reflect the filtration capabilities of the filter element. Therefore, often under the experimental conditions of the rule, the diameter of the largest hard spherical particles passing through the filter is taken as its affirmative filtration precision, which is used to directly reflect the filtering ability of the newly installed filter element.
The most important principle for the identification of hydraulic oil filter elements is the β value determined according to ISO4527-1981E (Multi-Pass Test), that is, the oil mixed into the standard experimental powder is repeatedly circulated through the filter, the oil inlet and the oil outlet. The ratio of the number of particles on both sides.
2. Flow characteristics: The flow rate of the filter element through the oil and the pressure drop are important parameters of the flow characteristics. The flow characteristics test should be carried out according to the ISO3968-91 specification to produce a flow-pressure drop characteristic curve. Under additional oil supply pressure, the total pressure drop (the sum of the filter shell pressure drop and the filter element pressure drop) should generally be below 0.2 MPa.
3. The strength of the filter element shall be determined by the break-impact test according to ISO2941-83. When the filter element is damaged, the pressure drop that drops sharply should be greater than the regular value.
4. Activity fatigue characteristics, 100,000 cycles of fatigue test should be carried out according to ISO3724-90.
5. For the test of hydraulic oil adaptability, the pressure flow endurance test shall be carried out according to the ISO2943-83 specification to verify the compatibility of the filter media with the hydraulic oil.
