The four-column hydraulic press is a device that uses liquid to transmit pressure: when the liquid transmits pressure in a closed container, it follows Pascal's law. The hydraulic transmission system of hydraulic equipment consists of power mechanism, control mechanism, actuator, auxiliary mechanism and working medium. The power mechanism usually uses an oil pump as the power mechanism, generally a positive displacement oil pump. In order to meet the requirements of the movement speed of the actuator, choose one oil pump or multiple oil pumps. Gear pump for low pressure (oil pressure less than 2.5MP); vane pump for medium pressure (oil pressure less than 6.3MP); plunger pump for high pressure (oil pressure less than 32.0MP).
The four-column hydraulic press is composed of two hydraulic cylinders of different sizes, which are filled with water or oil. Water-filled is called 'hydraulic press'; oil-filled is called 'hydraulic press'. There is a sliding piston in each of the two liquid cylinders. If a certain amount of pressure is added to the small piston, according to Pascal's law, the small piston will transmit this pressure to the large piston through the pressure of the liquid, and the large piston will be pushed up. Let the cross-sectional area of the small piston be S1, and the downward pressure on the small piston is F1. Thus, the pair of small pistons can be transferred in all directions by the liquid with constant size. The pressure on the big piston must also be equal to P. If the cross-sectional area of the large piston is S2, the upward pressure cross-sectional area generated by the pressure P on the large piston is a multiple of the cross-sectional area of the small piston. From the above formula, if a small force is added to the small piston, a large force will be obtained on the large piston. For this reason, a hydraulic press is used to press plywood, squeeze oil, extract heavy objects, and forge steel.
