1、1/87 *第二抽水站初步设计第二抽水站初步设计 摘要摘要：南水北调工程是解决我国北方地区水资源严重短缺的重大战略性举措， 也是关系到我国社会经济可持续发展的大型基础设施。*东风抽水站的初步 设计，是以南水北调东线一期工程为背景，是配合南水北调东线工程中淮安 泵站而平行布置的一座泵站，主要担负将淮安泵站提抽的水向北输送。该设 计包括主厂房、副厂房、引水渠、出水渠等。本泵站设计有三台机组，所选 泵型为 3100ZLQ-85，其设计扬程为 4.84m，单泵流量为 33.3m 3/s，转速为 150r/min。配套 TJ220040/3250 型电动机，采用直接传动。该泵站采用肘 形进水流道、虹吸式

2、出水流道。泵房形式为块基型泵房，该泵房的特点整体 性好，抗震能力强适用于立式机组。 该泵站采用 110kV 架空专用线路从距泵站 10km 处的变电所接电， 泵站设 110kV 专用变电所。110kV 母线在最大运行方式下三相短路容量为 1000MVA， 最小运行方式下三相短路容量为 800MVA。 每台电机的功率为 2200kW， 泵站设 计中对主机应用了先进的微机保护.主变压器则用了传统的继电保护。 结合泵 站的实际情况，主变压器选用两台 SL76300/110 主变。高压开关柜设置在 管理处主控室,低压开关柜设置在副站房。 THE PRELIMINARY DESIGNRING OF HU

3、AI YIN THE SECOND PUMPING STA TION Abstract: The South-North Water Diversion Project is a great strategic action of solving the water resource of northern area of our country seriously in short, it is 2/87 the large-scale infrastructure which concerns our countrys social economic sustainable develop

4、ment too。The preliminary designs of HUAI YIN THE SECOND pump station, regard the first stage of the project of east line of South-North Water Diversion as the background .It is built parallel with HUAI AN Pumping Station of the Eastern Route Scheme of South-North Water Diversion Project ,which is an

5、 anauxiliary Pumping Station.The main purpose is transporting the water which transported by HUAI AN pump station to the North. This pumping station contains main factory building,auxiliary plant,approach channel,outlet channel and so on. There are three 3100ZLQ-85 vertical axial-flow pumps which di

6、ameter is 4.87m,discharge is 33.3m3, rotate speed is 150r/min.Copulate motor is TJ2200-40/3250,direct driving.Design it with bell approach pipe, ,block structure pump building. The design of the veversible in let passage is elbow let passage and the design of the dewatering outlet is siphonic outlet pipe. The form of pump house adopted in pump station is a blockwork structure pump house , the characteristic globality of this pump house is good, antidetonation ability is suitable for the
