Effect of Trapped Volume on Volumetric Efficiency and Optimization of a Micro Two-dimensional Piston Pump
摘要
Abstract
This study investigates the effects of reverse flow,axial leakage,and circumferential leak-age on the volumetric efficiency of a micro two-dimensional(2D)piston pump through theoretical analy-sis,numerical simulation,and experimental testing.The results indicate that reverse flow is the primary cause of volumetric efficiency loss.Reducing the trapped volume can significantly decrease reverse flow and enhance volumetric efficiency;specifically,the efficiency increases by 13.31％at a working pressure of 35 MPa.关键词
