扬州大学本科生毕业设计摘要为满足某县城市排涝的需要，计划在距县城以东15km的新沟河上兴建排涝泵站。该泵站设计流量为14.0m3/s，设计扬程4.8m，最大扬程6.5m。选用900ZLB-85型立式轴流泵配JSL14-12型250kW电动机5台套。站房采用墩墙式湿室型结构，主要建筑物包括正向进水前池，进水池、泵房、隔墩、出水池等。本论文为新沟河排涝泵站的初步设计，报告内容包括水泵的选型，辅助设备选择，主要建筑物设计，稳定计算，结构计算等。关键词：泵站，轴流泵，流量，扬程AbstractInordertosatisfytheneedofsomecity’sfloodcontrol,anewconstructionofdrainageditchriverpumpingstationisbuiltin15kmeastofthecountyintheXingouriwer.Thedesignflowrateis14.4m3/sanddesignheadis4.2m,maximumheadis6.3m.Chooseverticalaxialflowpumpof900ZLB-85,with5setsofJSL14-12and250kWmotor.Thetypeofstationhouseiswetroomwall-type.Themainbuildingincludetheforbay,sump,pumpingstation,pier,theoutletpool,andsoon.Thepumpingstation,willplayanimportantroleinFloodcontrolsystemThereportincludestheselectionofpumps,auxiliaryequipmentselection,themainbuildingdesign,stabilityanalysis,structurecalculation,andsoon.KeyWords:pumpingstation;axial-fiowpump;flow;head目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc444000031"1综合说明PAGEREF_Toc444000031\h1HYPERLINK\l"_Toc444000032"1.1兴建缘由PAGEREF_Toc444000032\h1HYPERLINK\l"_Toc444000033"1.2工程水位情况PAGEREF_Toc444000033\h1HYPERLINK\l"_Toc444000034"1.3工程地质资料PAGEREF_Toc444000034\h1HYPERLINK\l"_Toc444000035"2.设计参数确定PAGEREF_Toc444000035\h2HYPERLINK\l"_Toc444000036"2.1设计流量PAGEREF_Toc444000036\h2HYPERLINK\l"_Toc444000037"2.2水位分析与特征扬程PAGEREF_Toc444000037\h2HYPERLINK\l"_Toc444000038"2.3建筑物等级PAGEREF_Toc444000038\h2HYPERLINK\l"_Toc444000039"3.主机组选型PAGEREF_Toc444000039\h3HYPERLINK\l"_Toc444000040"3.1水泵选型原则PAGEREF_Toc444000040\h3HYPERLINK\l"_Toc444000041"3.2水泵选型资料PAGEREF_Toc444000041\h3HYPERLINK\l"_Toc444000042"3.3水泵选型方案PAGEREF_Toc444000042\h3HYPERLINK\l"_Toc444000043"3.4动力机配套PAGEREF_Toc444000043\h5HYPERLINK\l"_Toc444000044"3.4.1动力机类型选择PAGEREF_Toc444000044\h5HYPERLINK\l"_Toc444000045"3.4.2传动装置选择PAGEREF_Toc444000045\h5HYPERLINK\l"_Toc444000046"3.4.3电动机的安装形式PAGEREF_Toc444000046\h5HYPERLINK\l"_T
