摘要(Abstract)：
针对以水作为介质的叶片泵内部泄漏的分析,建立了泄漏模型,分析了各泄漏通道的几何特点、运动特征和压差与泄漏量之间的关系。模拟各个泄漏通道的泄漏量,将计算的容积效率与试验测得的容积效率进行了比较,对各个泄漏通道的泄漏流量进行了分析,总结了影响容积效率的主要因素,结果为叶片泵的设计制造提供了理论依据。
The leakage model is established by the analysis to the clearance Leakage in Water Hydraulic Vane Pump.And it was analyzed the relation among the leakage rate and the leaking channels' geometric features,motion characteristics and pressure difference in detail.Each channel is simulated,and the volumetric efficiency which is calculated and the theoretical efficient volume are compared and analysised.The author sums up the most important factors to volumetric efficiency,whose research provides the oretical basis for designing the machine and methods for reducing the leakage rate.
