Hydraulic oil filter is a device used to filter solid impurities in the hydraulic system, which can keep the hydraulic oil clean and protect the normal work of the hydraulic system. In order to understand the characteristics of hydraulic oil filters in more detail, the following will be introduced around its different aspects:1. Filtration accuracy of hydraulic oil filter(1) A variety of precision classificationThe hydraulic oil filter can be divided into crude oil filter, ordinary oil filter, fine oil filter and special fine oil filter according to the filtration accuracy. These different accuracy levels can meet the requirements of various hydraulic systems for oil cleanliness.(2) High-precision filter materialsFilters usually use microporous filter paper, copper mesh, metal powder and other high-precision filter materials, which can capture particles as small as a few microns, so as to effectively ensure the cleanliness and stability of the hydraulic system.2. Structural characteristics of hydraulic oil filter (1) Compact design Hydraulic oil filters are usually compact in design, allowing them to be installed and used in small Spaces. This design not only saves space but also facilitates the layout and maintenance of the overall system.(2) Easy to replace the filter elementThe structural design of the filter takes into account the convenience of daily maintenance, and the replacement of the filter element and filter screen is usually simple and quick, without the need for complex tools or operating steps.3. How it works(1) Interception and adsorptionHydraulic oil filter mainly through direct interception and adsorption to complete the filtration effect. When the hydraulic oil flows into the filter from the filter, the impurities larger than the filter bore are blocked outside the filter, so as to purify the oil. Magnetic filters use magnetic forces to adsorb ferromagnetic particles in the oil.(2) Differential pressure workDuring the working process, with the accumulation of pollutants on the filter element, the pressure difference between the inlet and outlet sides of the filter will increase. When the pressure difference reaches a certain value, it is necessary to replace or clean the filter element in time to ensure the filtration effect and the stable operation of the system.4. Installation position of hydraulic oil filter (1) Oil suction filterInstalled in the oil suction port or suction line to prevent pollutants from entering the hydraulic pump. This filter generally uses a mesh or line gap filter without a shell, with large flow capacity and small resistance, so as not to affect the oil absorption performance of the pump.(2) Pressure line filterInstalled on the pressure oil circuit, mainly used to protect the downstream hydraulic components of the pump. This filter requires high filtration accuracy and must be able to withstand the maximum working pressure and peak pressure of the system.(3) Return oil filter: installed on the return oil line to remove impurities in the oil and provide clean oil for the system. Due to the low pressure of the return pipe, this filter has relatively low filtration accuracy and strength requirements.5. Scope of applicationHydraulic oil filters are suitable for all types of hydraulic systems, including agricultural machinery, industrial machinery, mobile equipment, aviation and Marine. Whether large hydraulic systems or precision equipment, hydraulic oil filters provide effective oil cleaning protection.6. Maintenance of hydraulic oil filter (1) Replace the filter element regularlyDuring the use of hydraulic oil filters, pollutants will gradually accumulate in the filter element, resulting in an increase in pressure difference and affecting the filtration effect. Therefore, regular inspection and replacement of the filter element is an important step to ensure the normal operation of the filter.(2) Cleaning and maintenanceFor washable filters, such as wire-gap filters, they can be cleaned during the replacement cycle to extend their service life. At the same time, the seals and connecting parts around the filter should be checked to ensure that there is no leakage.In summary, the hydraulic oil filter has the advantages of a variety of filtration accuracy, compact structural design, efficient working principle, flexible installation position, wide range of application and convenient maintenance. These characteristics make the hydraulic oil filter play a vital role in protecting the normal operation of the hydraulic system and extending the service life of the components.

Keep the hydraulic system clean(1) Avoid the entry of pollutantsWhen adding new oil or replacing the filter element, ensure that the working environment and tools are clean to prevent impurities from entering the system.(2) Clean the tank regularlyPeriodically clean the bottom of the tank of sediment and impurities to reduce pollution sources.4. Control the operating temperature(1) Monitor the temperatureControl the working temperature of the hydraulic system within a reasonable range to avoid excessive temperature leading to faster oxidation of hydraulic oil.(2) Cooling measuresFor high temperature conditions, forced cooling measures can be taken, such as increasing the cooler or improving the heat dissipation conditions.5. Optimize the filtration scheme(1) Combined filtration schemeAccording to the requirements of the system, the combined filtration scheme is adopted, such as the combination of the return oil filter and the high-precision filter to improve the overall filtration effect.(2) Full flow filtrationFull flow filters are installed in important areas to ensure that all flowing hydraulic oil is fully filtered.6.
