【摘要】：螺杆泵具有输送介质平稳、振动小、吸上性能好等优点,运动部件少、结构简单。随着螺杆泵技术的发展,应用范围越来越广,几乎能输送所有的介质,同时对其技术要求也越来越高。本文以杭州兴龙泵业有限公司的主导产品单螺杆泵为研究对象,分析其重要工作部件转子和定子的端面型线形成过程,研究了螺杆泵结构参数、工作参数对其性能的影响。针对泵类产品及其零部件的特点,提出一种适合螺杆泵设计的参数化变型设计方法。在此基础上,研究了基于变型设计技术的螺杆泵优化设计系统,开发了该优化设计平台的各个功能模块,并通过开发实例实现了这种新型的变型设计系统。在此基础上,本文对三维设计软件SolidWorks进行二次开发,研究了螺杆泵定、转子参数化建模所涉及的关键技术,实现了螺杆泵定、转子的参数化实体建模过程。根据螺杆泵摆线类型、变幅系数K和螺杆头数N的不同建立了多种螺杆泵的仿真模型,利用SolidWorks自带的COSMOSMotion工具研究分析了螺杆泵转子等距线上的速度和加速度等运动特性。并利用ANSYS软件分析了在均匀压力和非均匀压力作用下,螺杆泵定子应力、应变以及轮廓线的变形规律。本论文的研究具有重要的理论和现实意义,为螺杆泵的设计制造及企业产品管理提供了一个新的体系结构和实现方法,同时具有较高工程应用价值。
[Abstract]:Screw pump has the advantages of stable medium, small vibration, good suction performance, few moving parts and simple structure. With the development of screw pump technology, its application scope is more and more extensive, it can transport almost all media, at the same time, the technical requirement of screw pump is more and more high. In this paper, the main product of Hangzhou Xinglong pump Co., Ltd., single screw pump, is studied. The forming process of the end profile of rotor and stator is analyzed, and the structural parameters of screw pump and the influence of working parameters on its performance are studied. According to the characteristics of pump products and their parts, a parameterized variant design method suitable for screw pump design is proposed. On this basis, the optimization design system of screw pump based on variant design technology is studied, each functional module of the optimization design platform is developed, and the new variant design system is realized through an example. On the basis of this, the 3D design software SolidWorks is redeveloped in this paper, and the key technologies involved in the parametric modeling of screw pump and rotor are studied, and the parameterized solid modeling process of screw pump stator and rotor is realized. According to the type of cycloid of screw pump, the variation coefficient K and the number of screw head N, the simulation models of screw pump are established. The velocity and acceleration of the rotor isometric line of screw pump are studied and analyzed by using the COSMOSMotion tool of SolidWorks. The stress, strain and contour deformation of screw pump stator under uniform and non-uniform pressure are analyzed by ANSYS software. The research of this paper is of great theoretical and practical significance, which provides a new architecture and implementation method for the design and manufacture of screw pump and product management of enterprises, and has high engineering application value at the same time.
