| 摘 要： | 20世纪 70～ 80年代在西北地区为了农业生产修建了许多大中型高扬程泵站 ,各泵站或多或少都存在着年久老化问题 .而多级泵站又是一个包括各级泵站在内的复杂系统 ,系统内一个单元性能改变都会对系统产生影响 .采用单元化方法将多级泵站系统单元化 ,按每一级划分成子单元 ,引入各级泵站老化多指标综合评价的方法 ,建立了多级泵站系统中各泵站老化矩阵分析模型 ,并对甘肃景泰川高扬程提水灌区多级泵站系统进行模拟 ,分析计算出高扬程多级泵站系统内各级泵站综合老化隶属度的评价指标 .模拟计算结果基本与实际相吻合

| Abstract: | Multi-grade and high-lift pumping stations are rially complicated systems including many pumping stations and water pumps as well as other facilities.The changes in the parperties of one pumping unit may more orless influence the whole system.In this paper, a matrix model is developed by separating the system into subsystems and subunits and by using multi-indices of evaluation of system aging for pumping station.It can be used to determine the order of aging of the pumping system.The multi-grade pumping stations in Jingtai, Gansu province, are simualted as a case of study, and this model is employed to obtain the results of aging evaluation. |
