How does a hydraulic filter work on an excavator?
A hydraulic filter is a crucial component of an excavator that helps to keep the hydraulic system clean and free from debris. The hydraulic system controls the movement of various hydraulic cylinders and actuators of the excavator, such as the boom, arm, bucket, swing, and travel.
The hydraulic filter works by trapping solid particles, rust, and contaminants that can damage the hydraulic system. As the hydraulic fluid flows through the filter, it passes through a series of layers of filtration media that traps contaminants. The hydraulic fluid then returns to the hydraulic system, providing clean, filtered fluid.
Generally, hydraulic filters use a variety of filtration media, ranging from cellulose, synthetic fibers, metal mesh screens, or a combination of all three. The choice of filtration media depends on the type of contaminants present and the flow rate of the hydraulic fluid.
The hydraulic filter prevents contaminants from accumulating in the hydraulic system and ensures that the hydraulic fluid remains at optimal performance and durability. Unfiltered hydraulic fluid can cause damage to hydraulic components, reduce equipment efficiency, increase maintenance costs, and decrease the lifespan of an excavator.
To ensure the proper functioning and longevity of an excavator, regular hydraulic filter maintenance is crucial. It involves periodic replacement of the hydraulic filter bowl, checking the hydraulic filter element for clogging, and making sure the hydraulic filter bypass valve is functioning correctly.
