Importance of Filtration and Conditioning of Hydraulic Pumps

Blog | December 15th, 2015

In comparing electrical circuitry to hydraulic flow, we’ve discovered similarities. There are switching and branching instances in both systems. Resistance slows electrical current and a physical impedance slows the circulation of a fluid. Replete with comparisons, the analogy also extends to the pure state of the circulating medium,. Electricity must be clean of voltage spikes and transient power events, and so too must hydraulic fluid be cleansed of system-compromising pollutants.

Addressing the Filtration and Conditioning of Hydraulic Pumps

Hydraulic pumps are the heart and soul of the fluid transmitting realm. Just to underscore the importance of the apparatus, any hiccup seen in the pump will be transmitted across the entire network of fluid-carrying tubes and hoses. If the actuators are to respond smoothly and promptly, the pump must function without pause. Unfortunately, we’re talking about an ideal process, something that doesn’t exist outside of laboratory conditions. In the real world, unknown factors abound, and the worst of these are found in mechanism-corrupting contaminants. The technology used to banish dirt and other contaminants is realized through dense canisters, small palm-sized containers that pack special dirt-absorbing packages inside the frame. These vital fixtures are installed in-line, splitting the tubes of the hydraulic channels to block pollutants on a sub-micron level.

The Heart of the Matter

On daring to mix our metaphors, we’ve already made the comparison between electrical current and hydraulic fluid, but engineers have also been known to alter this paradigm. Instead, they describe the process in biological terms, placing the filtration and conditioning of hydraulic pumps within an organic framework. The logical reasoning behind this analogy should become obvious in a moment. The particulate matter trapped in the system serves only to hamper the efficient operation of the pump, reducing flow and driving the dirt into tight conduits that transform optimal flow into messy blockages. Like a heart fighting a fatty blockage, the mechanical arteries will deteriorate as pressure builds on one side of the barrier, and even if the blockage isn’t absolute, the viscous integrity of the hydraulic fluid is now reduced, broken down into a gritty stream that destroys the sensitive pressure differential required by a fast reacting set of actuators. Filters remove this gritty underflow, restoring purity to the system. Additionally, the conditioning side of this cleanliness equation works hard to restore viscosity and the non-compressible nature of the fluid, which typically reaches its lowest ebb when water enters the pipes and hoses. Unpredictable fluid consistency places unnecessary strain on the pistons and valves of the pump mechanism.

Handling external environmental infringements with designs that reject all forms of contaminants, water or dirt included, the filtration and conditioning of hydraulic pumps ensures actuator reactance remains snappy. The filters also stop parts from aging and succumbing to premature aging.
