AB In order to improve the precision of the extrusion speed control of the large hydraulic press and improve the quality of the extruding work piece, an experimental system was designed to simulate the throttle system of the hydraulic press. In order to simulate the transient heavy load and the fluctuating load characteristics of the throttle system, two pumps were used to supply the oil in the two chambers of the load cylinder separately, and the pressure of the two cavity of the load cylinder is controlled by two proportional relief valves. The force of the throttle spool driving cylinder can be controlled by controlling the pressure of the two chambers in closed loop, and the load state can be quickly changed. Experiments show that the load simulator can simulate the load form of the hydraulic press very well.
