Technical requirements of hydraulic filter:

(1) The filter material should have a certain mechanical strength to ensure that it will not be damaged by the action of hydraulic pressure under a certain working pressure. (2) Under a certain working temperature, the performance should be kept stable; it should have sufficient durability. (3) It has good anti-corrosion ability. (4) The structure is as simple as possible and the size is compact. (5) Easy to clean and maintain, easy to replace the filter element. (6) Low cost. The working principle of the hydraulic filter: the working principle of the filter. The hydraulic oil enters the pipeline from the left to the filter, flows from the outer filter element to the inner core, and then flows out from the outlet. When the outer filter element is blocked, the pressure increases and reaches the overflow. When the opening pressure of the flow valve is increased, the oil passes through the overflow valve, reaches the inner core, and then flows out from the outlet. The outer filter element has higher precision than the inner filter element, and the inner filter element belongs to coarse filtration. Hydraulic filter experimental method: The international standard ISO4572 has been widely used in various countries in the world to evaluate the “multiple-pass method of hydraulic filter element filtration performance”. Scale capacity. The multiple-pass method simulates the actual working conditions of the filter in the hydraulic system. The pollutants continuously invade the system oil and are continuously filtered out by the filter, while the particles that cannot be filtered out return to the fuel tank and pass the filter again. device. In order to meet the needs of high-precision filter performance evaluation, and due to the change of test dust and the adoption of new calibration methods for automatic particle counters, ISO4572 has been revised and improved in recent years. ISO16889.
