【Abstract】 This paper introduces the working principle and deduces the equations of geometric flow, average flow, instantaneous flow and the pulsation of the pump. After analyzing the pulsation of the pump in the case: z 1=3k and z 1=3k±1 , the paper points out that the pump has many advantages, such as big flow, good flow and so on.更多还原
