Example Embodiment
[0029] As shown in figure (1): the frequency conversion motor 2 forms a hydraulic power source through frequency conversion speed regulation and the variable hydraulic pump 3. Since the hydraulic pumps have a minimum speed (n>200r / min), when the invention is used to control the flow, when the flow is When it is smaller, it is controlled by changing the pump displacement; when the flow is greater than the minimum value, it is controlled by changing the speed of the electric frequency motor, and when the pressure is controlled, it is controlled by changing the pump displacement. The straightening process is a process of heavy load, large flow, and high response. The dynamic response speed of the variable frequency motor is slow. In order to prevent the flow of the hydraulic pump from being unable to meet the response requirements of the system instantaneously, an accumulator group 13 is connected to the outlet of the hydraulic pump. As an energy storage element, the accumulator ha...
