Calculation Method for the Theoretical Displacement of Cycloidal Pump

Abstract:

Based on meshing principle, a calculation method for profile curves in a kind of cycloidal pump was proposed. According to the definition of the theoretical displacement and the accurate profile coordinates of cycloidal pump, the accurate calculation method for displacement was obtained. The accuracy comparison between this method and the usual approximation equation for the displacement was also given in this paper. The results show that this method can get the precise theoretical displacement of cycloidal pump, is convenient for the scientists and technicians reference to design and manufacture directly.
