Forklift hydraulic oil temperature is too high

The following Boxin Xiaobian shares with you the hazards of forklift hydraulic oil temperature too high:

1 Hydraulic oil viscosity, volumetric efficiency, and working efficiency of the hydraulic system all decrease, leakage increases, and even mechanical equipment cannot work properly.


2 The parts of the hydraulic system expand due to overheating, destroying the normal matching clearance of relative moving parts, resulting in increased frictional resistance and easy seizure of hydraulic valves. At the same time, the lubricating oil film becomes thinner and mechanical wear increases, resulting in the pump, valve, The mating surface of the motor or the like is worn out due to premature wear or it is scrapped.


3 Accelerated rubber seal aging deterioration, shortened life, or even lose its sealing performance, so that the hydraulic system is a serious leak.


4 Vaporization of the oil and evaporation of water can easily cause cavitation in the hydraulic components. Oxidation of the oil forms colloidal deposits that can easily clog the oil filter and the holes in the hydraulic valve, making the hydraulic system unable to work properly.


Therefore, too high hydraulic oil temperature will seriously affect the normal use of the machine, reduce the service life of the hydraulic components, and increase the maintenance cost of the construction machinery.
