Abstract: The power aspect of traditional mud pump hydraulic adopts crank linkage. The change of pump-cylinder piston speed is
similar to the sine curve and so are the transient flow and pressure of discharging mud. Pulse volume is large and emission is
instability. By improving power-end , developed a new hydraulic mud pump, and pump cylinder movement will be a smooth,and
flow is stable. Application software AMESim established hydraulic system simulation models, and simulation analysis their dynamic
characteristics. The results showed that: End the use of hydraulic power systems, as long as a reasonable layout of the three-cylinder
piston pump initial position, as well as the speed ratio cylinder, h
