The working medium of hydraulic press powder molding machine manufacturers talk about it for you
The function of the working medium used in the hydraulic press is not only to transmit pressure, but also to ensure that the working parts of the machine work sensitively, reliably, with long life and less leakage. The basic requirements of the hydraulic machine for the working medium are ① suitable fluidity and low compressibility to improve transmission efficiency; ② anti-corrosion; ③ good lubrication performance; ④ easy to seal; ⑤ stable performance, temporary work and No deterioration. The hydraulic press uses water as the working medium at the beginning, and then uses an emulsion made by adding a small amount of emulsified oil to the water to increase lubricity and reduce rust. In the late 19th century, a hydraulic press with mineral oil as the working medium appeared. The oil has good lubricity, corrosion resistance and moderate viscosity, which is beneficial to improve the performance of the hydraulic machine.
