Horizontal hydraulic machine works. Large and small piston area are as S2, S1, the force on the plunger, respectively F2, F1. According to Pascal principle, sealed liquid pressure is equal everywhere, namely F2 / S2 = F1 / S1 = p; F2 = F1 (S2 / S1). Represents the gain of the hydraulic effect, and mechanical advantage, as force is increased, but not the power gain, and therefore a large moving distance of the plunger is a small movement of the plunger from the S1 / S2 times. The basic principle is to pump oil to the hydraulic cartridge valve block integration, through various check valves and pressure relief valve of the hydraulic oil cylinder assigned to the upper chamber, or lower chamber, the role of the high-pressure oil, so that the cylinder motion. Hydraulic Press is to use a liquid pressure transfer device. When the delivery pressure of the liquid in the closed container is to follow Pascal's law. Hydraulic hydraulic machine from the power transmission mechanism of control agencies, implementing agencies, assist institutions and media components. Power sector usually pump as the power agency, usually the product type pump. In order to meet the requirements of the actuator movement speed, use a pump or more pumps. Low (less than hydraulic 2.5MP) with gear pump; medium pressure (hydraulic less than 6.3MP) with a vane pump; high pressure (hydraulic less than 32.0MP) with a piston. Pressure of various plastic materials processing and forming, such as stainless steel extrusion, bending, deep drawing and cold-forming metal parts, but can be used for powder products, wheel, bakelite, thermosetting resin products repression.
