What Does A Hydraulic Filter Do?

Hydraulic fluid is the most important part of every hydraulic system. In hydraulics, no system works without a proper volume of hydraulic fluid. Also, any variation in fluid level, fluid properties, etc.. can damage the entire system we are using. If the hydraulic fluid has this much importance, then what will happen if it gets contaminated?

The risk of hydraulic fluid contamination increases based on the increased usage of the hydraulic system. Leakages, rust, aeration, cavitation, damaged seals, etc… make the hydraulic fluid contaminated. Such contaminated hydraulic fluids created problems are classified into degradation, transient, and catastrophic failures. Degradation is a failure classification that affects the normal working of the hydraulic system by slowing down the operations. Transient is an intermittent failure that occurs at irregular intervals. Finally, catastrophic failure is the complete end of your hydraulic system. The contaminated hydraulic fluid problems can become severe. Then, how do we protect the hydraulic system from contaminants?

Hydraulic fluid filtration is the only solution to eliminate contaminants from fluid in use. Particle filtration using different types of filters will remove the contaminant particles like metals, fibers, silica, elastomers and rust from the hydraulic fluid.

What Does A Hydraulic Filter Do?

(1) The filter material should have a certain mechanical strength to ensure that it will not be damaged by hydraulic pressure under a certain working pressure. (2) Under a certain working temperature, the performance should be stable; it should have sufficient durability. (3) 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: as shown in Figure 1, the schematic diagram of 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 pressure increases and reaches the opening pressure of the overflow valve, the oil passes through the overflow valve, to the inner core, and then flows out from the outlet. The outer filter element has a higher precision than the inner filter element, and the inner filter element belongs to coarse filtration. Hydraulic filter test method: The international standard ISO4572 has been widely adopted by countries all over the world to assess the “multiple pass method of the filtration performance of hydraulic filter elements”. The test content includes determining the filter element, the pressure difference characteristics of the plugging process for different sizes of filtration ratios (β values), and Staining capacity. The multiple-pass method simulates the actual working conditions of the filter in the hydraulic system. Pollutants continue to invade the system oil and are continuously filtered out by the filter, while the unfiltered particles return to the tank and pass the filter again. Device. In order to meet the needs of high-precision filter performance evaluation, as well as due to the changes in test dust and the adoption of new calibration methods for automatic particle counters, ISO4572 has been modified and improved in recent years. After the modification, the new standard number has been passed through the test method several times. ISO16889.
