Hydraulic oil performance requirements

Hydraulic oil performance requirements In the hydraulic system, the hydraulic oil in addition to the transmission of movement and power, but also from the role of lubrication and cooling, for which should have the following properties: ① appropriate viscosity, good viscosity-temperature properties; ② good lubricating properties , When the working pressure and temperature changes, should have a high film strength; ③ composition of pure, less impurities; ④ metal and seal have good compatibility; ⑤ with good chemical stability and thermal stability, Oil is not easy to oxidation, not perishable; ⑥ anti-foam, anti-emulsification, corrosive, anti-rust; ⑦ low pour point and freezing point, flash point Oil itself does not burn when the temperature) and ignition point; ⑧ harmless to the human body, low cost.
