水泵安装的基本要求和现场维护
泵的安装尽可能接近供液源（减少吸入扬程）。有足够空间，便于操作（安装、检修、读数等）。考虑防洪。控制最高，最低水位。安装使用说明书的目的是协助操作人员正确安装泵组及使泵组始终在有效而可靠的条件下运行。
设备现场的维护：泵应储存在干燥的地方，法兰保护盖和外罩均应留在泵上。轴承、联轴器等须仔细保护，以防被泥沙和其它杂质弄脏。如泵要储存一段较长的时间，则要采取彻底的措施。如应仔细地用热空气吹干泵内湿气，并立即用诸如防锈油、轻油、煤油等保护液涂在泵的内部，以免零部件生锈。
基础应有足够的强度和刚度，并能吸收任何正常的应变或震动。泵组安装在钢架或其它建筑物上时，应直接装在上面，或尽量靠近主构件、主梁或主墙，并加以支撑，以免底座倾斜、变形而破坏平行度和同心度。泵的水平用垫铁或垫片找正。 吸入管路要尽量短而直。最好有1/50~1/100的斜度。吸入管直径大于泵吸入直径，并采用偏心渐缩管接头。如果吸水面低于泵的中心线，渐缩管平直的一侧应安装在顶部。如果吸水面高于泵的中心线，则渐缩管平直的一侧应安装在底部。具有静吸上高度的泵装置，其垂直吸入管的进口潜没在液面下的深度最好为吸入管径的四倍以上。
排出管路：通常排出管上要安装逆止阀，也安装闸阀。逆止阀位于泵和闸阀之间，保护泵免遭驱动装置发生意外故障时造成的倒流或另一台泵运转时所产生的倒流。闸阀用于泵的引水或停车检修。大型泵（如电站的循泵）的排出管路通常只装液控蝶阀。管路应变：在泵安装和运行时，管路不应将过大的作用力和力矩加在与其联接的泵上，否则会使泵弹动，或使泵偏离原位。吸入管和排出管以及所有有关的阀门、滤网等都必须固定支承在泵附近，但要独立于泵，以免应变传递到泵体上。
