hydraulic cutting machine hermosetting resin products of repression

the hydraulic machine works Hydraulic works. Large and small area of ​​the piston of S2, S1, to make the hydraulic piston
Force respectively F2, F1. hydraulic cutting machine According to Pascal's principle, the same throughout the sealed fluid pressure, i.e. F2/S2 = F1/S1 = p; F2 = F1 (S2/S1). Represents the gain of the hydraulic effect, the mechanical advantage, as the force increases, but does not gain power, so a large movement of the plunger the plunger movement from a small distance S1 / S 2-fold.
Basic principle is to pump the hydraulic fluid delivered to the integrated cartridge valve block, through the various check valve and pressure relief valve assigned to the hydraulic oil cylinder upper chamber, or lower chamber, the role of oil in the high pressure, so that the cylinder exercise. Hydraulic the use of the pressure fluid to pass hydraulic hose assemblies the device. Liquid transfer in a sealed pressure vessel is to follow Pascal's law. Column hydraulic machine hydraulic system from the power sector, the control mechanism, actuators, auxiliary bodies and working media components. Power mechanism usually used as a power pump body, usually integrated oil pump. In order to meet the requirements of the actuator velocity, use a pump or multiple pumps. Low pressure (Hydraulic less than 2.5MP) with a gear pump; medium pressure (oil pressure is less than 6.3MP) with vane pump; pressure (oil pressure is less than 32.0MP) with a piston pump. Pressure of various plastic hydraulic ferrule materials processing and forming, such as stainless steel plate extrusion, bending, stretching and cold forming metal parts, but can be used for powder products, grinding wheel, bakelite, a thermosetting resin products of repression
