The purpose of the bypass valve of the return oil filter is mainly to prevent oil supply interruption when the filter element is blocked or the engine has just started, so as to protect the engine.The bypass valve is an important part of the oil filter, its role is not only to filter the oil, but also to ensure that in certain cases, even if the filter element is blocked, the oil can still reach the friction surface of the engine, providing the necessary lubrication protection. The details are as follows:1. Prevent dry wear damage of return filter bypass valve(1) When the oil filter is blocked due to long-term use, the bypass valve will automatically open, allowing the unfiltered oil to bypass the filter and enter the engine lubrication system directly. Although the oil may contain some impurities, it is much better than dry friction between engine parts.(2) When the engine is cold started, the resistance through the filter element increases due to the increase in oil viscosity. At this time, the bypass valve is opened to ensure that the oil reaches the lubrication part in time and reduces the wear during cold start.2. Maintain stable oil pressure of return filter bypass valve(1) The opening of the bypass valve is closely related to the oil pressure. When the filter block causes the pressure difference between the inlet and outlet to increase to a certain extent, the bypass valve will open the pressure relief to maintain the oil pressure within the safe range.(2) This design ensures that even in extreme cases, the oil supply will not be completely interrupted, ensuring the reliability and stability of the system.3. Avoid damage to filter element(1) If the filter element is blocked and without the protection of the bypass valve, the high-pressure oil may damage the filter element and even cause the filter element to break. The bypass valve protects the filter element from being damaged by releasing high pressure.(2) The existence of the bypass valve allows the filter element to be protected even in the case of blockage and extends its service life.4. Ensure immediate fuel supply of return filter bypass valve(1) When the engine needs more oil (such as high-load work or cold start), the bypass valve can respond immediately to ensure that the oil is directly filtered into the main oil channel to meet the immediate needs of the engine.(2) This immediate response mechanism ensures that the engine is adequately lubricated under various operating conditions, thereby improving overall performance.5. Adapt to different environments of return filter bypass valve(1) In different working environments (such as cold, high temperature, high humidity, etc.), the flow and lubrication effect of oil will be affected. The bypass valve can adjust the oil flow path according to the actual demand to adapt to different working environments.(2) This design enables the return oil filter to cope with a variety of working conditions and improve the adaptability and reliability of the system.6. Improve system economy of return filter bypass valve(1) The design of the bypass valve reduces the frequent replacement caused by the blockage of the filter element and reduces maintenance costs.(2) At the same time, it also reduces the risk of engine maintenance caused by dry wear damage and improves the economic efficiency of the entire system.In summary, the bypass valve of the return oil filter effectively protects the normal operation of the engine under various working conditions by preventing dry wear damage, maintaining stable oil pressure, avoiding filter element damage, ensuring immediate oil supply, adapting to different environments and improving the system economy. During engine maintenance and use, the filter element should be checked and replaced regularly to ensure that the function of the bypass valve is performed to the best state.Quote InquiryContact us!

The relationship between filtration accuracy and flow is mutual influence, generally speaking, the higher the filtration accuracy, the smaller the flow through. This is because high-precision filters require a finer aperture to intercept smaller particles, which increases the resistance of the fluid through the filter, thereby reducing the flow rate. The following is the specific introduction:1. Influence of filtration accuracy(1) DefinitionFiltration accuracy is usually expressed in microns (μm), representing the size of the filter element aperture. The smaller the aperture, the smaller the particles that can be trapped, and the higher the filtration accuracy.(2) High-precision influenceWhen the filtration accuracy is high, the filter bore is small, and the resistance of the fluid passing is increased, resulting in a decrease in flow rate. Therefore, in applications that require high-precision filtration, such as aseptic pharmaceuticals or high-purity chemical production, lower flow rates are often accepted to ensure a high degree of purification.(3) Low precision impactIn contrast, coarse filtration allows larger particles to pass through, the filter aperture is larger, the fluid resistance is small, and the flow rate is larger. This is suitable for the initial interception of large particulate matter, such as industrial cooling water filtration or pretreatment filtration.2. Traffic impact(1) DefinitionFlow rate refers to the amount of fluid passing through the filter per unit time, usually expressed in liters per minute (L/min). This is an important indicator to evaluate the processing capacity of the filter.(2) High traffic requirementsIn application scenarios with high flow requirements, filters with larger filtering areas and lower filtering accuracy are usually required. For example, in large hydraulic systems, large flow filters may be required to ensure the normal operation of the system.(3) Low flow requirementsFor low flow requirements, small area, high-precision filters can be used. Such filters are suitable for fine filtration in laboratories or small scale precision equipment.3. The effect of filtration area(1) Relation between area and flowThe larger the filter area, the greater the flow through the filter. This is because the large area provides more fluid passage, reducing flow resistance. Modern hydraulic filters mostly use star-shaped folding structure, which greatly increases the filtration area, thereby improving the flow rate.(2) Practical applicationIn the actual design, the filter area can be increased by increasing the length of the filter element or using a folding design to meet the needs of high flow applications.4. Influence of medium viscosity of the filter(1) Medium characteristicsThe viscosity of the fluid can have a significant effect on the flow rate of the filter. Fluids with high viscosity have a harder time passing through the filter, resulting in reduced flow. For example, at low temperatures, the viscosity of the hydraulic oil increases, and the flow rate of the filter decreases accordingly.(2) Application precautionsWhen selecting a filter, the viscosity of the fluid in the actual working environment should be considered. In particular, special systems that work under high or low temperature conditions, such as heavy machinery hydraulic systems, should choose filters suitable for high-viscosity oils.5. The influence of pressure difference(1) Definition of pressure differenceThe pressure difference at both ends of the filter is the driving force to push the fluid through the filter, and there is a quadratic relationship between the pressure difference and the flow rate. The greater the pressure difference, the greater the flow rate, but too high a pressure difference may cause damage to the filter element.(2) Pressure difference managementWhen designing the hydraulic system, the appropriate filter size should be selected according to the pressure difference-flow characteristic curve of the filter to ensure that the system operates within the safe pressure difference range.In summary, there is a complex mutual restriction relationship between filtration accuracy and flow rate. In practical applications, it is necessary to comprehensively consider filtration accuracy, flow requirements, filtration area, medium viscosity and pressure difference and other factors, select or customize the appropriate filter to ensure the efficient and stable operation of the system.Quote InquiryContact us!

The role of hydraulic oil filter on oil mainly includes filtering impurities, extending the life of equipment, maintaining the system clean and so on. The quality of hydraulic oil directly affects the normal operation of the hydraulic system and the service life of the components, so the hydraulic oil filter plays a vital role in the system. Its specific functions are as follows:1. Filter impurities of hydraulic oil filterIn the process of use and storage, hydraulic oil will inevitably be mixed with various impurities, such as mechanical impurities (including rust, casting sand, welding slag, iron filings, etc.), dust and seal fragments generated during the working process, metal powder, etc. If these impurities are not filtered effectively, they will circulate in the system and cause many problems. Through the filtration of the hydraulic oil filter, these solid particles and some soft pollutants are directly blocked and adsorbed, so as to keep the oil clean.2. Extend the service life of the deviceThe components in the hydraulic system, especially some precision components such as hydraulic pumps, valves and cylinders, have high requirements for oil cleanliness. Contaminants can cause wear, blockage and even damage to these components, leading to system failure. Through effective filtration, the service life of these components can be significantly extended and failures due to contamination can be reduced. According to statistics, more than 75% of the failures in the hydraulic system are caused by hydraulic oil pollution.3. Keep the system clean of hydraulic oil filterHydraulic oil is easy to oxidize and deteriorate under high temperature and pressure working environment, resulting in organic pollutants such as gum, asphaltene and carbon slag, which will affect the chemical stability and performance of the oil. By removing these harmful substances, the filter maintains the chemical stability of the oil and avoids system failures caused by oil deterioration.4. Improve system efficiency of hydraulic oil filterWhen the oil contains a large number of solid particles and dirt, it will increase the internal friction and pressure loss of the hydraulic system, resulting in increased heating and energy consumption of the system. By removing these contaminants, the filter reduces internal friction and improves the efficiency and response of the system.In summary, hydraulic oil filters play a vital role in the hydraulic system. It ensures the cleanliness and stability of the hydraulic oil by filtering out solid impurities, preventing new pollutants from entering, reducing mechanical wear, protecting key components and maintaining the chemical stability of the oil and other mechanisms, thereby extending the service life of the oil and improving the efficiency and reliability of the system.Quote InquiryContact us!
