中文摘要：

针对往复柱塞泵采用的阀式配流结构存在结构松散、节流损失大、效率受工作频率影响大等问题,提出了一种结构简单紧凑、节流损失小、工作稳定、配流无滞后的往复柱塞泵转套式配流系统。论述了转套式配流系统的工作原理,建立了三种不同凸轮槽型线转套的运动学模型,对比分析了三种凸轮槽型线转套对配流系统运动学特性的影响,同时对传动销进行了剪切强度分析。结果表明,与其它两种凸轮槽线型相比,正弦凸轮槽线型转套角速度和角加速度的大小和幅值均较小,且无拐点、阶跃,转套转动相对平稳,配流系统各零件的所受冲击力小。

英文摘要：

According to the problems that loose structure,large throttling loss and Efficiency is affected by the operating frequency,when reciprocating plunger pump uses valve type orifice structure.Rotating-sleeve distributing-flow system for reciprocating plunger pump was put forward,which has the advantages of simple and compact structure,small throttling loss,stable work and assignment without delay.Described the working principle of rotary sleeve type flow system,established the kinematics model of three different cam groove liner,analyzed kinematics characteristics influence of distributing-flow system that three cam groove type rotating-sleeve effect on,and analyzed the shear strength of the drive pin.The numerical results showed that compared with the other two linear cam grooves,the angular velocity and angular acceleration of sinusoidal cam groove rotating-sleeve has smallest size and magnitude,and has no inflection point and step,and the rotating-sleeve can rotates relatively stable,the impact force of each parts of distributing-flow system is smallest.
