A Theoretical Study of the Effect of Inertia Force of the Vanes on Performance of Hydraulic Balanced Vane Pump by Using Advanced Hypertrochoid Curve at the Inner Surface of Its Stator

In the latest our work, the possibility of application of the advanced hypertrochoid curve in the inner surface of the stator of fixed displacement hydraulic balanced vane pump, theoretically, was studied. By considering the properties of this curve, sealing action between pressure and suction sides of the pump can be improved. One of the important characteristics of a new profile must be improving of the inertial reaction of the vanes in each position where these vanes have a radial movement because it causes a smooth sliding motion of the vanes, and hence, a higher performance of the pump while attaining a longer life of it. Then in the present paper, the effect of the inertial force of the vanes on the performance of the pump with this curve will be studied. The regular motion of the vanes on the inner surface of the stator with smooth profile suppresses the lateral reactional force applied to the vanes and results to diminish local wear of the vanes tip and noise
