When choosing a filter, you need to consider factors such as filter performance, material quality, water flow, brand and after-sales service. These considerations not only affect the performance of the filter, but also determine the stable operation and service life of the entire system. Here are some specific considerations:1. Filter performance(1) Filtration accuracyFilter accuracy is a key indicator of filter performance, which refers to the smallest particle diameter that the filter can intercept, usually in microns (μm). Different systems have different requirements for filtration accuracy, for example, the servo system generally recommends a filtration accuracy of 5μm, while the ordinary proportional system is between 9 and 10 levels, and the filtration accuracy is 10 to 20μm.(2) Retention rateThe retention rate indicates the filter's ability to intercept impurities, and an efficient filter should have an excellent retention rate. The accuracy of the filter screen, the uniformity of the aperture and the packaging technology of the filter element will affect the retention rate.(3) contaminant capacityContaminant capacity refers to the weight of contaminants that the filter element can hold before reaching the limit pressure difference. The selection of filter element with large capacity can reduce the replacement frequency and improve the stability of the system.2. Material quality(1) Filter materialCommon filter materials include paper, metal mesh, glass fiber and so on. Paper filters are usually disposable, while metal mesh filters can be cleaned and reused, but disposable filters are easier to maintain cleanliness.(2) Pressure and corrosion resistanceThe material of the filter needs to be able to withstand the highest working pressure and corrosive environment in the system, such as 316 stainless steel with excellent corrosion resistance.3. Water flow(1) Traffic demandThe filter should have sufficient through-flow capacity to handle the system flow without creating excessive pressure drops. The filtration capacity of the oil suction filter should be more than twice the pump flow rate to prevent affecting the oil absorption performance of the pump.(2) Pressure dropThe low pressure drop design can reduce the energy loss, specifically, the assembly pressure drop of the pressure oil filter should be ≤1bar, the return oil filter should be ≤0.5bar, and the oil suction filter should be ≤0.05bar.4. Brand service(1) Brand selectionTry to choose professional big brands, which are more guaranteed in quality control and after-sales service. Well-known brands such as Midea, Haier, etc., provide a three-year warranty, quality and price are closer to the people.(2) Replacement and maintenanceFilters should be designed to facilitate routine maintenance and cartridge replacement without the need for complex tools.5. Installation positionFilters at different locations have different performance requirements. For example, the oil suction filter needs to choose a model with strong circulation capacity to prevent the cavitation phenomenon; Pipeline filters pay attention to filtration accuracy and pressure resistance; The oil return filter needs to adapt to large oil return flow and low pressure requirements.6. Working conditions(1) Working environmentSelect the appropriate type and precision filter according to the working pressure of the hydraulic system, oil viscosity, working environment, etc. For example, in precision hydraulic systems, high-precision filters should be selected to ensure oil cleanliness.In summary, when selecting a filter, it is necessary to consider factors such as filter performance, material quality, water flow, brand and after-sales service, installation location and working conditions. This not only helps to protect the normal operation of the hydraulic system and extend the service life of the components, but also improves the operating efficiency and stability of the entire system.Quote InquiryContact us!

Extending the service life of the hydraulic oil filter is very important to maintain the normal operation of the hydraulic system and reduce maintenance costs. The specific analysis is as follows:1. Check the filter element regularlyDuring use, the filter element will be continuously eroded by pollutants, so it is essential to check the condition of the filter element regularly. During inspection, attention should be paid to whether there is obvious wear, damage or deformation on the surface of the filter element. If the problem is found, the filter element should be replaced in time to avoid affecting the normal operation of the hydraulic system.2. Replace the filter element in timeAccording to the use of the equipment and the manufacturer's recommendations, develop a reasonable filter replacement cycle. Timely replacement of the filter element can effectively prevent the damage of pollutants to the hydraulic system and extend the service life of the equipment.3. Keep the hydraulic oil cleanThe cleanliness of the hydraulic oil has a great impact on the service life of the filter element. Therefore, the hydraulic oil should be filtered and replaced regularly to ensure the cleanliness of the hydraulic oil. In addition, pollutants such as water and metal particles should be avoided from entering the hydraulic system to reduce the burden on the filter element.4. Set filtering accuracy reasonablyThe filtration accuracy of the filter element should be selected according to the working requirements of the hydraulic system and the degree of pollution. The high filtration accuracy may cause the filter element to clog too quickly and affect the service life; If the filtration accuracy is too low, the pollutants cannot be effectively filtered and the normal operation of the hydraulic system will be affected. Therefore, a reasonable setting of filtration accuracy is helpful to extend the service life of the filter element.5. Clean the filter element regularlyWhen replacing the hydraulic oil, the filter element can be cleaned. When cleaning, you can use a special cleaning agent, gently scrub the surface of the filter, and then dry with compressed air. After cleaning, the filter element should be dried or desiccant should be used to remove excess water to prevent rust.6. Avoid leaving the filter cartridge empty for a long timeIf the filter is not used for a long time, it may lead to moisture, rust or aging of the filter. Therefore, when the hydraulic equipment is not used, the power should be turned off, and the filter element should be stored in a dry and cool place to extend its service life.7. Choose high quality filter element productsHigh quality filter element products have better filtration performance and longer service life. For example, Hedecker hydraulic industrial filter can effectively filter solid particles and colloidal substances in the working medium, control the degree of pollution of the working medium, thereby extending the service life of the hydraulic system.8. Optimize the workflow of the hydraulic systemBy optimizing the work flow of the hydraulic system, the working pressure and load of the filter can be reduced, thus extending the service life of the filter. For example, the combined hydraulic filtration scheme can improve the filtration effect without changing the existing oil return filter scheme.9. Regularly train operation and maintenance personnelEnsuring that operators and maintenance personnel understand how to properly inspect and maintain hydraulic oil filters can significantly extend the service life of the filter element. The training content should include the inspection method of the filter element, the replacement cycle, the cleaning method and the troubleshooting.10. Use an auxiliary filtration systemThe installation of auxiliary filtration systems in the hydraulic system, such as pipe filters or tank fueling and ventilation filters, allows additional filtration of the hydraulic oil at key locations, thereby reducing the work load of the main filter element and extending its service life.To sum up, extending the service life of hydraulic oil filters needs to start from many aspects, including regular inspection and replacement of filter elements, keeping hydraulic oil clean, reasonable setting of filtration accuracy, regular cleaning of filter elements, avoiding long-term vacancy, selecting high-quality filter products, optimizing workflow, training operation and maintenance personnel and using auxiliary filtration systems. Through these measures, the service life of the hydraulic oil filter can be effectively extended, to ensure the stable operation of the hydraulic system, and to reduce maintenance costs.Quote InquiryContact us!
