How to Adjustable Speed Of Hydraulic Press
Following are the main methods about how to adjustable the speed of hydraulic press. Adjusting the flow of hydraulic pump ● Variable pump adjustment: If the hydraulic press adopts variable pump oil supply system, the displacement of the pump can be directly adjusted to control the flow. For example, for axial piston variable pump, the output flow of the pump can be changed by changing the inclination angle of the swash plate. When the inclination angle of the swash plate increases, the displacement of the pump increases, the oil flow entering the hydraulic cylinder increases, and the working speed of the hydraulic press will increase; conversely, the inclination angle of the swash plate decreases and the speed slows down. This adjustment method has high accuracy and can achieve stepless speed regulation in a large range. ● Dosing pump with flow control valve: For hydraulic presses supplied by dosing pumps, flow control valves such as throttle valves and speed control valves are us...
