Technical parameters of hydraulic oil filter element

1. Filtering performance

Filtering accuracy: 2-200 μ m

Filtration ratio: tested according to the ISO 4527-1981 standard to measure the interception efficiency of the filter element on pollutant particles

2. Pressure and flow characteristics

Working pressure: Conventional models can withstand a pressure of 1.0MPa, while high-pressure models can reach 32-42MPa (equivalent to system pressure)

Pressure drop range: Total pressure drop under rated fuel supply pressure ≤ 0.2MPa (ISO 3968 standard)

Flow characteristics: Flow pressure drop curve testing is required to ensure that the flow capacity matches the system requirements

3. Environmental adaptability

Working temperature: -30 ℃~+110 ℃, some special models can withstand high temperatures up to 135 ℃

Media compatibility: Suitable for mineral oil, emulsion, water ethylene glycol, and phosphate ester hydraulic fluids

4. Structural strength and lifespan

Burst pressure: Tested according to ISO 2941-83 standard to ensure that the filter element is not damaged under high pressure difference

Fatigue characteristics: Verified long-term reliability through 100000 cycles of testing according to ISO 3724-90 standard

Cleanability: Some stainless steel mesh filter cartridges support reuse, reducing maintenance costs

5. Installation and application

Installation position: Oil suction pipeline (precision 100-180 μ m), pressure pipeline (5-10 μ m) or return pipeline

Applicable equipment: injection molding machines, hydraulic presses, wind power equipment, construction machinery, etc
