Hedec Hydraulic Oil Filter Liming Hydraulic Oil Filter Oil Removal Filter How to Use a Suitable Hydraulic Oil Filter
The hydraulic oil filter marked on the manufacturer's product sample or label is the nominal precision, not the absolute filtration precision. Only Only the b value that has been tested experimentally can indicate the filtration capacity of the filter element. The hydraulic oil filter element is also required to meet the pressure loss requirements to ensure the optimization of flow rate and filter element service life. When choosing a filter element, you can choose original parts or second brands. It should be noted that the selected filter element must be accepted to check whether it meets the performance indicators it should have. Filtration accuracy: First, determine the cleanliness level of stains according to the needs of the hydraulic system, and then select the filtration accuracy of the oil filter according to the attached table based on this cleanliness level. The nominal filtration cleanliness of the hydraulic oil filter element commonly used in engineering machinery is the nominal filtration accuracy of the hydraulic oil cleanliness filter element. Application range / Hydraulic servo valve / Hydraulic proportional valve / General hydraulic components > / General hydraulic components < Since the nominal accuracy cannot truly reflect the filter element Therefore, the diameter of the largest hard spherical particle that the filter can pass under specified experimental conditions is often used as its absolute filtration accuracy, which directly reflects the initial filtration capacity of the newly installed filter element. The most important standard for evaluating hydraulic oil filter elements is based on the b value measured through multiple experiments, that is, the ratio of the number of particles on both sides of the oil inlet and oil outlet when the oil mixed with standard experimental powder is circulated through the oil filter multiple times. Flow characteristics: The flow rate and pressure drop of the oil passing through the filter element are important parameters of the flow characteristics. Conduct flow characteristics experiments according to standards to draw the flow pressure drop characteristic curve. Under the rated oil supply pressure, the total pressure drop of the filter housing and the pressure drop of the filter housing are The sum of filter elements should generally be below. The strength of the filter element should be tested in accordance with standards for rupture and impact resistance. The pressure difference that drops sharply when the filter element is damaged should be greater than the specified value. Flow fatigue characteristics should be subjected to fatigue tests of 10,000 cycles in accordance with standards. Tests on the adaptability of hydraulic oil should be carried out in accordance with standards to test the pressure flow endurance to verify the compatibility of the filter material with hydraulic oil.
