IEC 63132-3:20 20 IEC 63132这一部分的目的是以一般方式建立立式混流式水轮机或水泵水轮机安装的合适程序和公差。本文档提出了典型的组件，并且每当在本文档中使用单词“涡轮机”时，其指的是立式混流式涡轮机或泵-涡轮机。有许多可能的方法来组装一个单元。机器的尺寸、机器的设计、动力室的布局或部件的交付时间表是可能导致附加步骤、消除一些步骤和/或组装顺序的一些要素。 据了解，这种类型的出版物只有在缔约双方都同意的情况下才具有约束力。 本文件排除纯粹商业利益的事项，与安装行为密不可分的除外。本文件中的公差是根据最佳实践和经验确定的，尽管公认其他标准规定了不同的公差。 如果本文件规定文件、图纸或信息由制造商（或多个制造商）提供，则每个制造商将仅为其自己的供应提供适当的信息。

IEC 63132-3:2020 The purpose of this this part of IEC 63132 is to establish, in a general way, suitable procedures and tolerances for the installation of a vertical Francis turbine or pump-turbine. This document presents a typical assembly and whenever the word “turbine” is used in this document, it refers to a vertical Francis turbine or a pump-turbine. There are many possible ways to assemble a unit. The size of the machine, design of the machine, layout of the powerhouse or delivery schedule of the components are some of the elements that could result in additional steps, the elimination of some steps and/or assembly sequences.
It is understood that a publication of this type will be binding only if, and to the extent that, both contracting parties have agreed upon it.
This document excludes matters of purely commercial interest, except those inextricably bound up with the conduct of installation.
The tolerances in this document have been established upon best practices and experience, although it is recognized that other standards specify different tolerances.
Wherever this document specifies that documents, drawings or information is supplied by a manufacturer (or by manufacturers), each individual manufacturer will furnish the appropriate information for their own supply only.
