  The role of the working medium used in the hydraulic press

  The role of the working medium used in the hydraulic press is not only to impart pressure, but also to ensure that the machine working parts work sensitive, reliable, long life and less leakage.

  The basic requirements of the hydraulic press on the working medium are: ① have the appropriate liquidity and low compressibility, in order to improve the efficiency of transmission; ② have good lubrication performance; ③ anti-rust; ④ easy to seal; ⑤ stable performance, long-term work Without deterioration.

  The hydraulic press was originally used as a working medium, and later changed to add a small amount of emulsified oil in the water to increase lubricity and reduce corrosion. In the late 19th century there was a hydraulic machine with mineral oil as the working medium. The oil has good lubricity, corrosion resistance and moderate viscosity, which is beneficial to improve the performance of hydraulic press. The second half of the 20th century there has been a new type of water-based emulsion, water-based emulsion emulsification is "water-in", rather than the original "oil-in-water." "Water-in-oil" emulsion of the external phase of the oil, its lubrication and corrosion resistance close to the oil, and little oil, not easy to burn. But the price of water-based emulsions is more expensive, limiting its popularity.
