Design and Research of Numerical Presure Pump

A new type numerical pump is developed to control pressure.It consists of a simple-structured volume -type pump as an integrated product controlled by a microcomputer.It can change the volume or pressure of pump through the control of output angle and rotational speed by the pre-established program in controller.Because the pump directly controls the actuator pressure,many controlling valves are saved and the control circuit becomes simple and e- conomic.It also has a better application prospect.
