1. The hydraulic press uses the pressure regulating valve to adjust the size of the hydraulic press.

2. Hydraulic press is a kind of equipment that uses solution as working material and is made according to Pascal principle to transmit kinetic energy to complete various processing processes. The hydraulic press is generally composed of the equipment (server), power unit and hydraulic press automatic control system. Hydraulic press is classified into valve hydraulic press, liquid hydraulic press and project hydraulic press.

3. The basic concept of hydraulic press is that the gasoline pump transmits the hydraulic oil to the integrated hydraulic control one-way valve block. According to each product and speed regulating valve, the hydraulic oil is distributed to the chest, abdominal cavity or lower cavity of the hydraulic cylinder to enable the hydraulic cylinder to carry out fitness exercise under the effect of high-pressure oil. Hydraulic press is a machine equipment that transmits working pressure with the help of liquid state. Pascal's law is followed when liquid propagates working pressure in closed vessels. The hydraulic transmission system of four column hydraulic press is composed of driving force organization, control organization, actuator, auxiliary organization and working material. The driving force organization generally takes the high-pressure oil pump as the driving force organization, which is generally an integral gasoline pump. In order to better meet the requirements of the fitness exercise rate of the actuator, one gasoline pump or several gasoline pumps are used. Gear oil pump for low voltage (steam pressure lower than 2.5MP); Axial piston pump for high pressure (steam pressure lower than 6.3mp); Gear pump for high pressure (steam pressure lower than 32.0mp). The working pressure production, processing and forming of various ductility materials, such as extrusion molding, bending and deep drawing of stainless steel plates and cold extrusion molding of metal parts. At the same time, it can also be used to inhibit powder products, sand wheel pieces, bakelite powder and epoxy thermosetting plastic products.
