Hydraulic Press System - Working Pressure
When design of hydraulic press system, the system working pressure is often pre-determined (selected according to the design model referring to the relevant materials), and then according to the requirements of each actuator for the movement speed, the hydraulic system flow can be determined after detailed calculation. When the external load is fixed, the higher the system pressure is selected, the smaller the geometric size of each hydraulic component is, and a lighter and more compact structure can be obtained. Especially for large excavators, it is more important to select a higher working pressure. The working pressure of the primary selection system is not equal to the actual working pressure of the system. After the system design is completed, according to the load cycle diagram of the actuator, according to the selected effective area of the two chambers of the hydraulic cylinder and the displaceme
