Research Of Radial Double Ball Pston Pump

Radial double ball piston pump is a dual-ball plunger-type structure piston pump, it has the characteristics of high output pressure and high power density. When the pump is working via the double ball joint replace ball contact with the inner wall of the track, this increases ball contact area with the track, thereby reducing the rail contact stress between ball and, to extend the service life of the pump, so it can output high pressure liquid. Distribution flow through axial valve and stator curve using ellipse.This paper analyses the following study on radial double ball piston pump:Characteristics of hydraulic technology in the first place and the current status of radial piston pump, pointing out that related research of key technology of radial plunger pump stator curve and significance of radial piston pumps, which proposes a new structure of radial double ball piston pump, and the radial pair of ball plunger pump structure and principles are described in detail.Then derive the trajectories of hinge Centre of stator curve equation and solving the radial double ball piston pump flow and pulse formula, and two goals in different structure, link to twice the distance from the center of the RADIUS and the eccentricity of stator curve on the ripple effect of radial double ball piston pump.Last pulse capable of radial double ball piston pump structure from motion and mechanical property analyses in two ways. By stator curve ball is derived the equations of motion, emulation of a piston and the trajectory of the ball, two ball stopper on the pressure angle of the orbit changes, and pump structural change of parameter values on the effects of velocity, acceleration and jerk. Analysis when the pump runs at different stages of force, analysis and simulation of connecting rod of two forces, track ball two ball piston and cylinder bore on piston end support, both inside and outside curves. According to Hooke and Hertz theory, orbital and the cylinder bore and piston, and analysis of the contact stress between the two ball. And pointed out that in some locations the track and contact stress distribution between the two ball.By examining the content, for radial ball piston pump subsequent pair of structure optimization and manufacturing.
