The function of working medium used in hydraulic press is not only to transfer pressure, but also to ensure the working parts of the machine are sensitive, reliable, long life and less leakage.The basic requirement of hydraulic press for working medium is that it has suitable fluidity and low compressibility, so as to improve the efficiency of transmission.Jasmine can prevent corrosion;Torque has good lubrication performance;Superior easy to seal;Transaction has stable performance and works for a long time without deterioration.The hydraulic press USES water as the working medium at first, and then USES emulsifying liquid formed by adding a small amount of emulsifying oil into the water to increase the lubrication and reduce corrosion.The oil press with mineral oil as working medium appeared in the late 19th century.The oil has good lubricity, anti-corrosive and moderate viscosity, which is beneficial to improve the performance of hydraulic press.In the second half of the 20th century, a new type of water-based emulsifying solution was developed. The emulsifying form was "oil inclusion water" rather than the original "water inclusion oil".The outer phase of the emulsion is oil. Its lubricity and corrosion resistance are close to oil, and it contains little oil and is not easy to burn.However, the price of water-based emulsion is high, which limits its promotion.
