中文摘要：

遥观南枢纽泵站工程是新沟河延伸拓浚工程的干河枢纽工程之一,其主要任务是抽排武进港地区的水入京杭大运河,兼顾排涝。该泵站设计净扬程仅为0.7m,属超低扬程泵站。根据已建泵站工程模型泵装置试验成果,从水力性能、工程投资、施工和运行管理等方面进行综合比较,选用了已在溧阳新村枢纽成功应用的贯流泵水力模型。考虑到该泵站的最大扬程接近设计扬程的3倍,还对电机定速和调速方案进行了投资及运行成本比较,发现调速方案机泵投资较大,但运行成本的降低并不显著,因此最终采用定速方案。

英文摘要：

Yaoguannan pumping station is one of the key projects in the Xingouhe extension and widening project,and its main task is to pump water from the Wujing Port area to the Bejing-Hangzhou Grand Canal and to storm drainage as well.The design pump head of the pumping station is extra-low,which is only 0.7m.Based on the test results of model pump system from the constructed pump station projects and the comparisons from the perspectives of hydraulic performance,engineering investment,construction,and operation management,the tubular pump model that has been successfully adopted in the Liyangxincun pumping station was selected for the Yaoguannan pumping station.Due to that the maximum pump head is about 3times of the design head,the investment and operation costs for the Yaoguannan pumping station were analyzed between two design schemes of fixed and adjustable motor speeds.The investment for the pump set was much larger but the effect in lowering operation cost was not obvious for the scheme of adjustable motor speed,thus the fixed speed scheme was selected finally.
