ANSI/HI 2.3-2013标准自2008年以来首次更新并重新发布。本标准的目的是为各种用途的旋转动力verical泵的设计和应用，以及使用此类泵时需要采取的特点和必要的预防措施提供指南。本标准涵盖的旋转动力立式泵的类型有:立式涡轮机混流轴流立式扩散器潜水电机深井短装泵、VS0、VS1、VS2、VS3、VS6、VS7和VS8型。这些泵由垂直电机或带直角齿轮的卧式发动机驱动。不在本文件范围内的是垂直的- 立式安装的管道蜗壳泵和离心蜗壳泵，如污水泵。

Updated and republished, the ANSI/HI 2.3-2013 standard has returned for the first time since 2008. The purpose of this standard is to create a guide for the design and application of rotodynamic verical pumps for various services, as well as the features and necessary precautions needed to be taken when using this type of pump. Types of rotodynamic vertical pumps covered in this standard are:Vertical TurbineMixed FlowAxial Flow Vertical DiffuserSubmersible Motor DeepwellShort-Set Pumps, types VS0, VS1, VS2, VS3, VS6, VS7 and VS8These pumps are driven by vertical electric motors or horizontal engines with right-angle gears. Excluded from the scope of this document are vertical in-line volute pumps and centrifugal volute pumps mounted vertically, such as sewage pumps.
