Working Principle
This filter element is a high-pressure precision filtration component. Its core achieves precise filtration of hydraulic oil and system safety protection through the collaborative mechanism of “filter material retention of impurities – bypass valve overload protection – check valve backflow prevention”. The specific process is as follows:
1. Filter the core process
High-pressure hydraulic oil enters the inner cavity of the filter housing from the filter element inlet. When it flows through the pores of the glass fiber folded filter material, the filter material intercepts solid impurities with a particle size of ≥10 μm in the oil (such as metal grinding debris, dust, rubber particles, etc.) through mechanical interception, inertial collision and adsorption. The filtered clean oil enters the main circuit of the system through the outlet of the filter element, providing a clean oil source for precision components such as the hydraulic pump and valve group.
2. Overload protection mechanism
When the filter material retains too many impurities and causes blockage, the pressure difference between the inlet and outlet of the filter element gradually increases. When the pressure difference reaches 4.0 MPa±0.5 MPa, the built-in bypass valve automatically opens, and the high-pressure oil directly flows from the inlet to the outlet through the bypass valve, preventing the filter element from breaking due to excessive pressure difference, and at the same time preventing the system from being damaged due to sudden pressure rise or lack of oil in components caused by blocked oil flow.
3. Reverse anti-pollution mechanism
A check valve is installed on the outlet side of the filter element. When the system shuts down or the pressure drops sharply, the check valve closes quickly under the reverse pressure of the oil, preventing the contaminated oil downstream from flowing back to the clean side of the filter element and avoiding the re-entry of retained impurities into the system, ensuring that the initial cleanliness of the oil meets the standards when it is started next time.Iii. Product Features and Advantages
– High precision filtration efficiency: With an absolute filtration accuracy of 10 μm and glass fiber folded filter material, β10≥1000 (i.e., the retention efficiency for 10 μm impurities ≥99.9%), it can enhance the oil cleanliness from ISO 18/15 grade to 16/13 grade, effectively reducing the wear of precision components such as hydraulic valves and pumps, and extending their service life by more than 30%.
– Excellent high-pressure resistance performance: With a rated working pressure of 31.5MPa and a 3mm thick carbon steel casing, it can withstand a short-term high-pressure impact of 42MPa. Fluororubber seals provide reliable sealing under high pressure with no leakage risk, making them suitable for high-pressure hydraulic systems such as excavators and presses.
– Large dirt-holding capacity and long service life: The folded filter material design increases the filtration area by 4 times compared to filter elements of the same volume. The dirt-holding capacity is ≥ 15g, and the normal service life under working conditions is ≥2000 hours. Compared with ordinary filter elements, the replacement frequency is reduced by 50%, reducing operation and maintenance costs.
– Complete safety protection function: The built-in bypass valve and check valve form dual protection. The bypass valve prevents the filter element from clogging and breaking, and the check valve avoids oil backflow and contamination. The surface of the filter housing is treated with electrostatic powder coating, which has excellent anti-rust performance and is suitable for outdoor working conditions that are humid and dusty.
Iv. Usage Functions and Purposes
1. Core usage functions
– Precision filtration of hydraulic oil: It retains solid impurities of 10 μm or more in the hydraulic oil, reduces the contamination level of the oil, prevents faults such as valve jamming and pump body wear caused by impurities, replaces traditional low-precision filter elements, and enhances system reliability.
– System high-pressure safety protection: When used in series in high-pressure pipelines, it can not only filter impurities but also ensure the flow of oil when the filter element is clogged through a bypass valve, preventing system pressure overload. There is no need to install an additional relief valve, simplifying the system structure.
– Maintenance of oil cleanliness: In combination with the suction oil filter element and the return oil filter element, it forms a three-stage filtration system, maintaining the oil cleanliness within ISO 16/13 grades for a long time, extending the hydraulic oil replacement cycle to over 8,000 hours, and saving 15% energy compared to systems without fine filtration.
2. Main application fields

– Hydraulic press filtration scenario: It is used in the main cylinder circuit of a 2000-ton press to filter high-pressure oil (pressure 25 MPa, flow rate 120 L/min), intercept metal particles generated by cylinder wear, prevent damage to the main cylinder seal, and extend the seal replacement cycle from 3,000 hours to 5,000 hours.
– Mining tunnel boring machine filtration scenario: It is matched with the hydraulic system of the mining tunnel boring machine, filtering the high-pressure oil (pressure 31.5 MPa, flow rate 160 L/min) in the drive circuit of the tunnel boring head. It has excellent anti-dust pollution ability and a service life of up to 2000 hours in the underground dusty environment, which is twice as long as that of ordinary filter elements.

1. Medium and Selection management
– Strictly compatible with the type of hydraulic oil, glass fiber filter materials are prohibited from being used in media containing corrosive solvents such as chlorine and ketone. Select the model based on the system pressure (≤31.5 MPa), flow rate (≤160 L/min) and impurity particle size (≥10 μm). It is strictly prohibited to use beyond the parameters.
Before the new system is used for the first time, the pipeline should be flushed with a temporary filter element for more than 40 minutes to remove installation impurities before replacing the filter element. When changing the hydraulic oil in the system, the filter element must be replaced simultaneously to prevent contamination by the mixture of new and old oil.
2. Installation and commissioning
Before installation, confirm the inlet and outlet directions of the filter element (marked “IN” on the shell for inlet and “OUT” for outlet). Reverse installation is strictly prohibited (reverse installation will cause the filter to fail and damage the check valve). When making flange connections, the bolts should be evenly tightened with a torque of 500 N·m, and the gasket should be coated with oil-resistant sealant.
During commissioning, first introduce low-pressure oil (5 MPa) to flush the filter element for 10 minutes, and then gradually increase the pressure to the rated level. After installation, the pressure difference between the inlet and outlet of the filter element needs to be checked (an initial pressure of ≤0.15 MPa is normal). The pressure difference often requires checking whether the installation is in place or whether the filter element is clogged.
When installed outdoors or in a humid environment, a waterproof and breathable cap should be added to the top of the filter housing to prevent rainwater from seeping in and causing the filter element to rust. A maintenance space of ≥ 100mm is reserved around the filter element to facilitate replacement operations.
3. Operation and Maintenance
During operation, monitor the pressure difference between the inlet and outlet of the filter element weekly. When the pressure difference is ≥0.3 MPa or reaches the 2000-hour service life, the filter element must be replaced immediately. When replacing, the system pressure must be turned off. Disassemble only after the pressure drops to 0 MPa to avoid injury from high-pressure oil spraying.
The spent filter elements that have been replaced must be collected and treated centrally. It is strictly prohibited to disassemble them at will (the filter materials contain oil stains, which can easily cause environmental pollution). Before installing the new filter element, it is necessary to check whether the packaging is intact. It is strictly forbidden to use damaged or damp filter elements.
It is strictly prohibited to operate for a long time with the bypass valve open (the oil is not filtered after the bypass valve is open, which will accelerate the wear of system components). If the pressure difference surges frequently, it is necessary to check whether there is abnormal wear in the system (such as the wear of the pump body and cylinder block generating a large amount of impurities).
4. Storage protection
Unused filter elements should be stored in their original packaging and sealed. They should be kept in a dry warehouse at 0-45℃ with a humidity of no more than 60%, avoiding direct sunlight, heavy object compression and oil contamination. It is strictly prohibited to store it together with corrosive gases or chemicals to prevent the filter material from deteriorating.
The storage validity period of the filter element is 2 years. If it is not used within the period, the filtration performance of the filter material (such as bubble point test) needs to be retested. Only after meeting the standards can it be used. Idle filter elements should have their packaging sealing checked every six months. If damaged, they need to be resealed.
