The adverse consequences of high pressure oil temperature:
(1) The increase of oil temperature reduces the viscosity of the oil, so the leakage of oil in the components and the system will increase, which will reduce the volumetric efficiency of the hydraulic pump of the press.
(2) The increase of the oil temperature reduces the viscosity of the oil, which increases the flow of the oil through the throttling orifice or the slit valve, which changes the originally adjusted working speed and affects the stability of the press. , reduce the working accuracy.
(3) After the oil temperature increases and the viscosity decreases, the lubricating oil film between the relatively moving surfaces will become thinner, which will increase the mechanical wear and cause failures when the oil is not clean.
(4) The rise of oil temperature will cause thermal deformation of mechanical components, and hydraulic valve components will expand after heating, which may reduce the fitting clearance, thus affecting the movement of the spool of the press, increasing wear, and even getting stuck.
(5) The rise of oil temperature will accelerate the oxidation of the oil, which will lead to the deterioration of the oil and reduce the service life of the oil. Sediments such as asphalt precipitated in the oil will also block the small holes and gaps of the components, affecting the normal operation of the press system.
(6) If the oil temperature is too high, the sealing device of the press will be rapidly aged and deteriorated, and the sealing performance will be lost.
