3050022 Radiator Hose Pipe Hydraulic Hose For Excavator EX200-2 EX200-3

When hydraulic hose is used for its primary purpose of joining ports on two moving components, it must be flexible enough to bend as the components move, such as between the jib and boom arms of an excavator. The flexibility of the hose is determined by its pressure rating (and number of reinforcement windings), its diameter and its material construction. Hoses used in this fashion are equipped on mobile equipment of every type, cable carriers on injection molding machines or automation, hydraulic presses, tractor implements, et al.

Hydraulic hose is also the plumbing of choice to dampen noise and vibration in hydraulic machinery. Some pump types emit pressure waves into the fluid as gears or pistons reach the pressure chamber, which in turn resonates and vibrates metal plumbing or components. This resonance is related to the combined size, shape, mass and geometry of the plumbing, components, reservoir and fittings. This resonance is difficult to predict before a power unit or machine is fabried. However, the annoying resonance can be improved by swapping rigid tube or pipe with hydraulic hose. Hose’s innate elasticity and flexibility can absorb some vibration caused by pumps, reducing the resonance, or changing its pitch, so that noise is reduced in intensity.
