Core advantages of return oil filter
The return oil filter has the core advantages of efficient filtration and intelligent protection, and is widely used in hydraulic systems. It adopts new materials such as glass fiber and synthetic fiber filter cartridges, with a filtration accuracy of 1-30 μ m and a filtration efficiency of ≥ 99.5%, in compliance with ISO standards. It can effectively intercept pollutants such as metal particles and rubber impurities, prevent component wear and system failure. The equipment is equipped with a pressure differential signaling device. When the filter element is clogged and the pressure differential reaches 0.35MPa, an alarm will be triggered immediately to prompt maintenance; If the pressure rises to 0.4 MPa, the bypass valve will automatically open to maintain the operation of the system, avoiding the risk of shutdown caused by clogged filter elements. In addition, its compact structure allows for direct installation on the top or side of the fuel tank, simplifying pipeline design and saving space; The diffuser structure reduces the generation of oil return bubbles, prevents the backflow of pollutants, and extends the service life of the oil. Some models, such as the RFB series, are also equipped with permanent magnets that can filter out ferromagnetic particles larger than 1 μ m, further reducing the risk of system contamination. In the fields of metallurgy, petrochemicals, and mechanical manufacturing, return oil filters significantly improve system reliability and reduce maintenance costs through high-precision filtration and multiple protection mechanisms.
Although the return oil filter has significant advantages, its application still has certain limitations. Firstly, the cost of replacing the filter element is relatively high. If the filter element made of synthetic fiber, paper or other materials becomes clogged, it needs to be replaced as a whole. Long term use may increase maintenance budget; Secondly, the adaptability to extreme working conditions is limited. For example, high temperature environments may cause the filter element material to age and reduce filtration efficiency. Therefore, it is necessary to choose high-temperature resistant sintered filter elements or strengthen cooling measures; In addition, some users have misconceptions, such as ignoring the pollution risk after the bypass valve is opened - when the bypass valve is blocked by the filter element or opened at low temperatures, unfiltered pollutants may re-enter the system, accelerating component wear. Therefore, it is necessary to regularly monitor the status of the filter element, replace it in a timely manner, and avoid long-term dependence on the operation of the bypass valve. Overall, the return oil filter has significantly reduced the impact of drawbacks through technological optimization, but in scenarios requiring high precision and reliability, it still needs to be selected and maintained reasonably based on system operating conditions.
