1广蓄电站水工高压隧洞设计施工的若干问题显示文摘本文根据广州抽水蓄能电站建成的高水头、大直径水工隧洞的工程实践,回顾总结设计施工的几个问题,如设计准则、衬砌〈限裂〉设计、外水压力、钢筋混凝土衬砌岔管、斜井衬砌滑模施工、衬砌分缝和止水、引水系统充水和放空操作等。Ye Jisheng (Guangdong Pumped Storage JVC\ Guangzhou\ 510600) 1998水力发电学报1998,17,2:30
2EXPERIMENTAL STUDY ON HIGH-SPEED CENTRIFUGAL PUMPS WITH DIFFERENT IMPELLERS显示文摘The experimental study is carded out on high-speed centrifugal pumps with three different impellers. The ex-perimental results and analysis show that high-speed centrifugal pumps with a closed complex impeller can achieve thehighest efficiency and the lowest head coefficient followed by those with half-open impeller and open-impeller, and canobtain much easily stable head-capacity characrastic curve, while those with a half-open complex impeller can't. Thecharacteristic curve with a open impeller is almost constant horizontal line before dropping sharply. The results also showthat the axial clearance between pump casing and impeller can influence greatly on the performance of centrifugal pumps.Zhu Zuchao Chen YingState Key Laboratory of Fluid Power Transmission and Control, Zhejiang University,Hangzhou 310027, ChinaHuang Dunhui Jin Qingming Cangnan Special Pumps Co.Ltd of Zhejiang Province 2002Chinese Journal of Mechanical Engineering2002,15,4:10
3离心式水泵叶栅流动研究显示文摘离心式水泵叶栅流动很复杂,必须采用试验与数据分析相结合的方法,才能真正有益于工程实践.本文主要介绍应用TSI二维激光多普勒测速仪探测离心式水泵叶栅流场,清晰地看到轴向涡旋对叶栅流动的影响,发现离心式泵叶栅出口处液流周向分速沿圆周变化不大.简单介绍了对试验水泵进行数据计算的结果.激光测速、流场显示以及三维数值分析结果都表明试验水泵叶片压力侧有严重的回流现象.The Research Group on Research on Blade Cascade Flow of the Centrifugal Pump (College of Mechanical and Electrical Engineering, College of Civil Engineering and Architecture, Northern Jiaotong University, Beijing 100044) 1998北方交通大学学报1998,22,5:3
4Operation Performance of Central Solar Heating System with Seasonal Storage Water Tank in Harbin显示文摘This paper presented a preliminary research on the central solar heating system with seasonal storage(CSHSSS)used in cold climate in China.A mathematical model of the solar energy seasonal storage water tank used in the central solar heating system was firstly developed based on energy conservation.This was followed by the simulation of the CSHSSS used in a two-floor villa in Harbin,and analysis of the impacts on storage water temperature of tank volume,solar collector area,tank burial depth,insulation thickness around the tank,etc.The results show there is a relatively economical tank volume to optimize the system efficiency,which decreases with increasing tank volume at the constant collector area,and increases with increasing collector area at the constant tank volume.Furthermore,the insulation thickness has obvious effect on avoiding heat loss,while the tank burial depth doesn't.In addition,the relationship between the solar collector efficiency and storage water temperature is also obtained,it decreases quickly with increasing storing water temperature,and then increases slowly after starting space heating system.These may be helpful for relevant design and optimization in cold climates in China and all over the world.YE Ling1,JIANG Yi-qiang1,YAO Yang1,ZHANG Shi-cong2(1.Institute of Heat Pump and Air Conditioning Technology,Harbin Institute of Technology,Harbin,Heilongjiang 150090,China 2.Institute of Built Environment and Energy Efficiency,China Academy of Building Research,Beijing 100013,China) 2009湖南大学学报(自然科学版)2009,36,S1:2

20Experimental Research of Pressure Distribution in the Casing of Inducer显示文摘In this paper the inducer of the advanced-researched pump is studied. During multi-rotation speed experimentwith the medium of water, the dynamic pressures near inducer casing are obtained by transducer at each measuringpoint mounted on the casing along the axial direction, both in the steady rotation speed period and the up anddown period. Bases on analyses, the regularity of the axial distribution of time averaged pressure and pressurepulsation amplitude, the connection between pressure pulsation frequency and rotation speeds, and the relationshipbetween the pressure pulsation amplitude and the site of inducer blade are obtained.Wu Yuzhen and Huang HaoNational Engineering Research Center for Specific Pump and Valve Beijing,China,Zip:100076 Chief Engineer 2009Journal of Thermal Science2009,18,4:1
