Wankel pump designs have not been fully established, with existing designs limited to bicornous rotor pumps and triangular rotor pumps. Here, on the basis of Wankel geometry, we present a tetragonal rotor pump with a three-lobe epicycloid and its conjugate envelope as chamber and rotor profile. First, the design method and basic working principle of the pump are introduced. Four groups of prototypes with different shape factors were manufactured, and their flow and pressure characteristics were experimentally studied. Numerical study showed that the flow rate irregularity of the pump is lower than that of existing Wankel pumps. Finally, the feasibility the pump for mixing applications was verified by a flow field observation experiment. The work in this paper provides a new type of rotary displacement pump design, representing an study of reverse application of a Wankel engine structure.
汪克尔泵的设计尚未完全确立，现有设计仅限于双角转子泵和三角转子泵。在此，基于汪克尔几何结构，我们提出一种具有三叶外摆线及其共轭包络作为腔室和转子轮廓的四方转子泵。首先，介绍了该泵的设计方法和基本工作原理。制造了四组具有不同形状因子的原型，并对其流量和压力特性进行了实验研究。数值研究表明，该泵的流量不均匀性低于现有汪克尔泵。最后，通过流场观测实验验证了该泵用于混合应用的可行性。本文的工作提供了一种新型旋转容积泵设计，代表了对汪克尔发动机结构反向应用的研究。
