EA4923 pleated industrial hydraulic oil filter element is a high-performance filter element designed specifically for industrial hydraulic systems. It adopts advanced pleated filter structure and combines high-quality glass fiber filter material, with significant advantages such as high-precision filtration, high temperature and high pressure resistance, and long service life. This filter element can effectively intercept pollutants such as metal particles, dust, and moisture in hydraulic oil, ensuring the cleanliness of the oil, extending the service life of key components in the hydraulic system, and reducing equipment failure rates and maintenance costs.
| Brand Name | DFFILTRI |
| Maximum operating temperature | -30℃~95℃ (suitable for wide temperature environment, resistant to high temperature and high pressure) |
| Scope of application | Construction machinery (crane, pump truck), energy and power (gas turbine), petrochemical industry (refining equipment), etc |
| Corrosion resistance | Acid and alkali resistance, oil corrosion resistance (suitable for complex working environments) |
The core structure of EA4923 filter element is a pleated design, which significantly improves the pollutant holding capacity and filtration efficiency by increasing the filtration area (usually up to 1.5 square meters or more). Its filtration accuracy can reach 5 μ m, which can intercept small particles and meet the cleanliness requirements of high-precision hydraulic systems. The filter frame is made of galvanized steel plate or stainless steel material, which has high strength and corrosion resistance, and is suitable for a wide temperature working environment from -30 ℃ to 95 ℃. In addition, the filter element adopts a sealed design at both ends to prevent oil leakage and ensure system stability.
1. In the field of construction machinery, it is widely used in hydraulic systems of equipment such as gantry cranes, hoists, and pump trucks to filter impurities in the return oil pipeline and protect core components such as hydraulic pumps and valves.
2. In the field of industrial manufacturing, it is suitable for lubrication systems of large machinery such as rolling mills, continuous casting machines, injection molding machines, etc. It filters wear particles in lubricating oil and extends equipment life.
3. In the field of energy and power, in the lubrication system of gas turbines in thermal and nuclear power plants, metal debris generated during high-speed operation is filtered to ensure the safe operation of the system.
4. In the field of petrochemicals, hydraulic transmission systems used in refining and chemical production filter particles in intermediate products to prevent pipeline blockage and equipment wear.
1. Efficient filtration performance, combined with a pleated structure and high-density glass fiber material, achieves micron level filtration and cleanliness far exceeding industry standards.
2. Long lifespan and low maintenance, designed to withstand high temperatures and pressures, with a single use life of over 1000 hours, reducing replacement frequency and downtime.
3. Customized services, supporting customized filter specifications based on customer equipment models and operating parameters (such as inlet and outlet diameters, filtration area, etc.) to meet diverse needs.
4. Outstanding cost-effectiveness, with a price reduction of 30% -50% compared to imported brands, while maintaining the same filtering accuracy and stability.
1. Filter element blockage
Reason: Severe oil contamination or failure to replace the filter element on time.
Solution: Regularly check the cleanliness of the oil and replace the filter element every 1000 hours; If the blockage is severe, the fuel tank needs to be cleaned and replaced with new oil.
2. Filter deformation or rupture
Reason: The system pressure exceeds the pressure resistance value of the filter element (such as EA4923 with a maximum pressure difference of 9MPa).
Solution: Check if the system pressure exceeds the standard and replace the filter element with a higher pressure resistance level (such as EA4925).
3. Sealing failure leads to oil leakage
Reason: The sealing ring is aging or improperly installed.
Solution: Replace the fluororubber or nitrile rubber sealing ring to ensure that the torque during installation meets the specifications.
4. Decreased filtration efficiency
Reason: The filter element has been punctured or the material has failed.
Solution: Immediately stop the machine and replace the filter element, and check if there are any abnormal vibrations or high temperature conditions in the system.
