On Computing Leakage Flow of Plunger Pair in Radial-Plunger Pump
A new radial plunger pump is given which is installed with roller between plunger and stator, the roller is purely rolling on the inner face of stator, reducing the friction force and effectively avoiding the combustion of friction pair in working orde. When viscosity varies with pressure and temperature, hydraulic pressure and cutting flow caused by plunger moving in the plunger auxiliary of a new radial-plunger pump, the computing formula of annular gap is corrected here, which provide a theoretical support for developing a high efficient radial-plunger pump.
