 A fluid vaporization, evaporation, easy to make the hydraulic components to

generate cavitation; oil oxidized to form colloidal sediments, easy to plug the hole

in the oil filter and hydraulic valve, hydraulic system is not working properly.

Therefore, the hy draulic oil temperature is too high will seriously affect the hydraulic hose manufacturers

normal use of the machine, reducing the service life of hydraulic components, and

increase maintenance costs of construction machinery.
    2, to accelerate the rubber seals of aging deterioration, shortened life

expectancy, or even lose its sealing performance, serious leakage of the hydraulic hydraulic manifold block

system.
    3, parts of the hydraulic system due to overheating and expansion, and

destruction of the original normal with the gap in relative motion parts, resulting

in frictional resistance increase, the hydraulic valve is easy to get stuck at the hydraulic cutting machine< br />
same time, the lubricant film thinning, increased mechanical wear, resulting in

pumps, valves , motors, and other precision mating surface due to premature wear and

render ineffective or scrapped.
    4, the viscosity of hydraulic oil, volumetric efficiency and the efficiency of

the hydraulic system decreased, increased leakage, and even the machinery and

equipment does not work.
