Hydraulic Suction Strainer For Excavator Engine 903423776 EF-548A-100SIF. G5 Hydraulic Suction Filter Element

Product Description:

The hydraulic oil filter element and the oil suction filter element are both hydraulic system filtering components, but there are significant differences between the two in terms of installation position, function, accuracy, etc., as follows. In terms of installation position, the hydraulic oil filter element (usually referring to the return oil filter element) is installed in the return oil pipeline of the hydraulic system, between the hydraulic actuator and the oil tank, to filter the oil returning from the actuator to the oil tank;

The oil suction filter is installed at the oil suction port of the hydraulic pump, between the oil tank and the hydraulic pump, to filter the oil entering the hydraulic pump from the oil tank. Functionally, the core function of the hydraulic oil filter element is to filter impurities (such as metal shavings and rubber particles) generated during the operation of the hydraulic system, purify the return oil, prevent impurities from entering the system circulation again, and protect the actuator and hydraulic pump; The core function of the oil suction filter is to filter out large particles and impurities in the oil tank, prevent them from entering the hydraulic pump, avoid wear and tear of the hydraulic pump, and protect the hydraulic pump.

In terms of precision, the hydraulic oil filter element has a high filtration accuracy (1-50 μ m) and needs to filter out small impurities to ensure the cleanliness of the oil; The oil suction filter has a low filtration accuracy (60-100 μ m), mainly filtering large particle impurities to avoid blocking the oil suction port of the hydraulic pump and ensure normal oil suction of the hydraulic pump.

Features:

Filtration accuracy: Oil suction filters usually adopt a coarse filtration design (with a filtration accuracy of generally 80-100 μ m), mainly intercepting large particle impurities (such as metal shavings, fibers, etc.) in the oil to prevent them from entering the oil pump and avoid pump body wear or jamming.

Low pressure design: Due to its installation at the oil pump suction port, the filter needs to withstand low pressure (generally<0.1MPa), so the structure is simple and the resistance is low, ensuring smooth oil suction of the oil pump.

Connection method: The oil outlet is usually equipped with threaded or flanged connections to meet different pipeline requirements.

Material selection: The filter material is usually metal mesh or coarse fiber, which is corrosion-resistant, wear-resistant, and suitable for different working conditions.

Working medium: Suitable for various hydraulic media such as mineral oil and biodegradable hydraulic oil.

Temperature range: It can operate within a wide temperature range (such as -30C to+100C) and adapt to different environmental requirements.
Preventing cavitation: By coarse filtration, the bubbles and impurities in the oil are reduced, reducing the risk of cavitation in the oil pump.

Protect hydraulic components: prevent impurities from entering precision components such as valve groups and servo valves, and extend the overall life of the system.
