Excavator hydraulic filters are key components in hydraulic systems, primarily used to filter impurities (such as metal shavings, dust, and colloids) from the hydraulic oil, protecting precision components like hydraulic pumps and valves from contamination and wear. Their core function is to maintain the cleanliness of the hydraulic oil, ensuring stable system operation and extending equipment life.

Main Working Principles

Surface Filtration: Such as mesh or sintered filter elements, directly trapping particles larger than the pore size.

Deep Filtration: Such as paper or fiber filter elements, intercepting fine particles layer by layer through a multi-layered structure.

Composite Filtration: Some filters combine magnetic or backwashing functions to improve filtration efficiency.

When filter element blockage causes the pressure difference between the inlet and outlet to reach a set value (e.g., 0.35 MPa), the differential pressure transmitter will trigger an alarm, indicating that the filter element needs to be replaced.

Core Parameters and Types

Filtration Accuracy: Typically 1-100 microns, customizable (e.g., Gaohang filter elements support precision filtration).

Filter Element Material: Commonly glass fiber, polypropylene (PP), or stainless steel, resistant to high temperatures and corrosion.

Types: Includes suction filters, return filters, high-pressure filters, etc., installed in different locations within the hydraulic system as needed.
