立式斜流泵安装及其调试摘要：本文重点介绍了800VZNM型立式斜流泵安装及其调试，对安装过程中存在的问题的产生原因和如何对其采取整改以及安装流程、调试过程和注意事项的论述。

关键词：斜流泵；调试；整改；安装流程；注意事项1. 概况东莞市第六水厂，是采用臭氧－生物活性炭工艺进行深度处理的水厂。

由于比常规水处理多了一道工序，所以在设计上增加了多组臭氧接触池与炭滤池，需要将水位提升至6米，二期安装工程改用由中日合资生产的800VZNM型立式斜流泵，共4台机组。

2. 立式斜流泵的性能参数及其安装流量：4320m3/h，扬程：6.1m，转速：595r/min，功率：132KW2.1安装水泵出厂时，原则上水泵的一体组装在工厂内完成，但是也会有以零部件解体的状态出厂的状况，原因如下。

(1)泵体过长，搬运时需要解体。

(2)泵房的安装高度太低，没有足够的起吊空间。

解体出厂的水泵，在水泵安装现场进行组装。

2.1.1安装前的准备(1)安装动工前须充分研究讨论施工计划与图纸等资料。

(2)卸货吊入时，为了防止损坏零件，请务必注意以下事项。

(a)在起吊易变形的零部件时，还没有组装之前不要拆除它们的加固部件(轴固定部件等)。

(b)为了防止装配在水泵机体上的小配管、阀门、测量仪表等部件的破损，须小心搬运轻拿轻放。

(c)为了防止油漆脱落，请在钢丝绳与泵体接触的部位垫入保护物。

此外，确认钢丝绳不会脱落后，再起吊。

2.1.2安装时的注意事项(1)安装用垫铁(a)尽量把底座与基础面之间的垫铁放置在靠近基础螺栓的地方。

(b)垫铁组合一般有两种：2枚斜垫铁1枚平垫铁为一组；平垫铁2～3枚为一组。

(c)使用斜度为1/20～1/50的垫铁。

(2)基础螺栓的固定方法安装水泵时，最为常见的基础螺栓固定的施工方法有箱式方孔埋入的方法和使用模板（定位板）将基础螺栓与混凝土一起埋入的方法。

(a)箱式方孔埋入法是，浇注基础混凝土的时候事先预留出基础螺栓用的箱式方孔，装入水泵之后再将基础螺栓固定的施工方法。
