Hydraulic oil filter element, hydraulic filter element, metal fiber

Main parameters and characteristics

hydraulic oil filter elementIt is mainly made of stainless steel woven mesh, sintered mesh, and iron woven mesh as materials. Due to the use of mainly fiberglass filter paper, synthetic fiber filter paper, and wood pulp filter paper as filter media, it has high concentricity, high pressure resistance, and good straightness. Its structure is made of single-layer or multi-layer metal mesh and filter media. The number of layers and mesh size of the mesh used in specific use depend on different usage conditions and purposes

Hydraulic oil filter element, hydraulic filter element, metal fiberScope of Application

1. construction machinery

• Typical equipmentExcavators, cranes, bulldozers, loaders, etc.

• effectFilter metal shavings and wear particles in hydraulic oil to prevent valve core jamming and seal aging, especially in high-frequency operations where high-precision filter elements (such as ISO 4406 standard 10 μ m level) are required.

2. Industrial manufacturing equipment

• typical scenarioInjection molding machines, CNC machine tools, hydraulic stations for press machines.

• special requirementsTo withstand high temperature oil (such as above 300 ℃) and chemical additives, ceramic coatings or special polymer filters should be selected.

3. Mobile Machinery and Vehicles

• Equipment examplesForklifts, fire trucks, mining trucks.

• challengeIn harsh environments (dust, vibration), filter cartridges with strong anti clogging performance are often designed with foldable structures to adapt to compact spaces.

4. Ship and Ocean Engineering

• key applicationsServo system, anchor hydraulic device.

• requirementMust be certified with IP67 or higher protection level, resistant to salt spray corrosion, and have self-cleaning function in some scenarios.

5. Energy and Power Industry

• caseHydropower station gate control system, wind power variable pitch hydraulic cylinder.

• technical indicatorsHigh pressure environment (>21MPa) requires the use of steel wire wrapped reinforced filter element, with anti explosion pressure ≥ 4 times the working pressure

• temperature resistance：

• Polyether sulfone (PEEK): Long term use temperature ≤ 200 ℃, suitable for high-temperature forging hydraulic systems

• Fluororubber (FKM): Short term resistance to 300 ℃, commonly used in aerospace emergency braking systems

• Chemical corrosion resistance：

• 316L stainless steel: resistant to weak acids, bases, and hydrocarbon solvents, selected for the petrochemical industry

• Boron nitride coating: for ammonia containing media (such as rust proof oil for ship hydraulic systems)

• Special structural design：

• Gradient density structure: front coarse pores (20 μ m)+rear fine pores (5 μ m), balancing flow rate and accuracy

• Self cleaning sewage outlet: Automatically discharge accumulated impurities during continuous operation of construction machinery

  Proper selection of hydraulic filter element requires comprehensive considerationOperating pressure, oil compatibility, installation spaceEstablish and maintain a record of the three key elements through the PDCA cycle (plan execute check improve). It is recommended to configure online particle counters (such as PALL's LaserNet Fines) on key equipment to achieve quantitative management of pollution control.
