The adjusting method of the speed of the hydraulic press:
1. Control method of throttle speed regulation. The hydraulic press can use the quantitative pump to supply oil, and use the throttle element to change the oil distribution of the parallel branch, and then change the flow of the actuating element to realize the speed regulation.
2, the control method of volume speed regulation. The hydraulic machine realizes the speed regulation by changing the effective volume of the hydraulic pump.
3. Control method of volume throttle speed regulation. The hydraulic press can combine 1 and 2 methods, and use variable pump and throttling element to match the speed of executive parts of hydraulic press.
