During the use of hydraulic press, if the temperature is not well controlled, it will affect the normal use of hydraulic press. For the normal operation of this equipment, it will also bring some adverse effects. Therefore, the operator needs to know: after the oil temperature rises, what will be the impact?
, onceHydraulic pressThe increase in the oil temperature will reduce the viscosity of the oil, so the oil leakage in the components and system will gradually increase, which will gradually reduce the volumetric efficiency of the hydraulic pump. At the same time, the flow of oil through the orifice or gap valve will increase, which will change the working speed that has been adjusted, which will affect the stability of the work and reduce the working accuracy.
Second, the lubricating oil film generated between the relative moving surfaces will become thinner, which will increase the wear of the machine. When the oil is not very clean, it is easy to malfunction.
Third, the oil temperature rise, will make the mechanical components of thermal deformation, hydraulic valve components in the heat after the expansion, so with the gap is also reduced, so the movement of the spool will be affected, increased wear, there may be stuck.
Fourth, the rise of oil temperature will accelerate the oxidation of oil and cause the deterioration of oil, so as to reduce the use time of oil. In the oil, the precipitation of asphalt and other precipitates will block the small holes and gaps of the components, which will affect the normal operation of the system. Of course, this will also make the sealing device rapid aging, deterioration, and loss of sealing.
