High alumina ball hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy and achieve various processes. A hydraulic press generally consists of three parts: the main engine, the power system, and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses.

working principle

The working principle of hydraulic press. The areas of the large and small plunger are S2 and S1, respectively, and the forces acting on the plunger are F2 and F1, respectively. According to Pascal's principle, the pressure of a sealed liquid is equal everywhere, that is, F2/S2=F1/S1=p; F2=F1(S2/S1)。 The gain effect of hydraulic pressure is the same as mechanical gain, where the force increases but the work does not increase. Therefore, the movement distance of the large plunger is S1/S2 times that of the small plunger.

The basic principle is that the oil pump delivers hydraulic oil to the integrated plug-in valve block, and distributes the hydraulic oil to the upper or lower chamber of the cylinder through various one-way valves and relief valves. Under the action of high-pressure oil, the cylinder moves A hydraulic press is a device that uses liquid to transmit pressure. When a liquid transfers pressure in a closed container, it follows Pascal's law. The hydraulic transmission system of a four column hydraulic press consists of a power mechanism, a control mechanism, an actuator, an auxiliary mechanism, and a working medium. The power mechanism usually uses an oil pump as the power mechanism, usually an integral oil pump. To meet the requirements of the actuator's movement speed, one or multiple oil pumps should be selected. Gear pump for low pressure (oil pressure less than 2.5MP); Medium pressure (oil pressure less than 6.3MP) blade pump; Use a plunger pump for high pressure (oil pressure less than 32.0MP). The pressure processing and forming of various plastic materials, such as extrusion, bending, deep drawing of stainless steel plates and cold pressing of metal parts, can also be used for the pressing of powder products, grinding wheels, glued laminated wood, and thermosetting resin products.

Product Usage

This equipment is particularly suitable for various processes such as bending, forming, and flanging of central load parts. When equipped with a punching buffer device, it can also be used for punching and material processing. It is a product in industries such as shipbuilding, pressure vessel, and chemical engineering.
