一种新型微小内啮合渐开线齿轮泵的设计
Design of Novel Gear Pump with Miniature Internal Involute
摘要
Abstract
According to the requirement of plugging device in oilfield,we design a novel miniature internal involute gear pump by combining the mechanical pipe packer in oilfield and the hydraulic technology.Firstly,the structure and the working principle of the new gear pump are introduced,and the innovations and the functions are put forward.Then we determine the main design parameters of the pump.The simulation models of the main stressed parts-shell and gears,are established by a finite element analysis software,and the strength simulation is analyzed.According to the design parameters of the pump,the software ANSYS is used to establish the fluid model,and we simulate the internal flow field of the pump by ANSYS ICEM CFD.Finally,we analyze the key parts' processing technology and process an experimental prototype.We verify the indicators such as volumetric efficiency and total efficiency of the pump under load and no load conditions by experiments.The results show that the pump can meet the design requirements.关键词
