【摘要】：HR1O转子动力学试验台是受上海凯泉泵业集团委托,由浙江大学化工机械研究所高速旋转机械实验室设计开发的一套用于多级离心泵转子动力学测试的多功能试验台。同时也是国内第一套应用于企业生产设计研发的转子动力学性能测试平台,对于打破国外设备供应商的垄断地位,提升我国自主研发高性能多级离心泵的能力具有重要意义。本文从试验台主机入手,对主机机械结构进行了设计,给出了高速平带传动的设计参数,采用有限元的方法对支撑座的支撑刚度进行了仿真计算；开发了一套高性能试验台自动控制系统,对辅机系统工作流程进行了优化设计,提出了精确PID转速控制方法；对多级离心泵转子临界转速进行计算,得到了系统临界转速随某些参数变化(如支撑刚度、叶轮个数、支撑跨距)的规律,给离心泵转子的设计提供参考。借助在超高速试验机领域的优势和经验和现有的加工技术,攻破技术难关,成功设计开发了HR10型转子动力学试验台。最后在试验台上对真实多级离心泵转子进行了测试,证明试验台的开发是成功的。
[Abstract]:HR1O rotor dynamics test platform by Shanghai Kaiquan pump group commissioned by the Zhejiang University Institute of chemical machinery of high speed rotating machinery design and development of a set of laboratory test for rotor dynamic multistage centrifugal pump multi function test bench. The performance of the rotor dynamics test platform is also the first set used in enterprise production design and development, to break the foreign equipment suppliers monopoly, has important significance to enhance the capability of China's independent research and development of high performance centrifugal pump.
From the start of the test host, the host machine structure design, gives the design parameters of high-speed transmission belt, by using the finite element method on the supporting base of the support stiffness was calculated; the development of automatic control system of a high performance test bench, on the working process of the auxiliary system were optimized. The precise PID speed control method; the critical speed of the multistage centrifugal pump rotor are calculated, the critical speed of the system with the change of some parameters (such as stiffness, blade number, support span) rules, provide a reference for the design of centrifugal pump rotor.
With the advantage and experience in the field of high speed testing machine and the existing processing technology, break technical difficulties, successfully designed and developed HR10 type rotor dynamics test platform. The test at the end of the multistage centrifugal pump rotor in the real test bench test proved that the development is successful.
