Research on the Force on the Plunger and the Roller of the Static Pressure Supporting Cylinder Pair

摘要

A new radial plunger pump is given here, which is installed with a roller between the plunger and the stator. When in working order, the roller is purely rolling on the inner face of the stator, reducing the friction force and effectively avoiding the combustion of friction pair. The force on the roller and the plunger of the static pressure supporting cylinder pair are studied here and some theoretical evidences are provided for developing new radial-plunger pumps of high speed, high efficiency, and long lifetime.
