Based on the principle of sliding teeth transmission and the operation principle of sliding teeth gear pump,the structure principle of three-phase sliding teeth gear pump is presented, the fomula of tooth profile curve of the centre wheel is put forward, the equilibrium of radial oil pressure on three-phase cam is tested, the flow characteristics of both fixed displacement pump and change displacement pump are analyzed. Research results indicate that the new pump has equilibrium radial oil pressure, big displacement, small pulsation and low noise etc.
