水轮机安装程序和公差指南第3部分:立式混流式水轮机或水泵水轮机

[中文适用范围]： IEC 63132 的本部分旨在以通用方式制定立式混流式水轮机或水泵水轮机安装的适当程序和公差。本文件介绍了一种典型的组装方式，文件中出现的“水轮机”一词均指立式混流式水轮机或水泵水轮机。组装机组的方法有很多种。机器的尺寸、设计、发电厂的布局或部件的交付时间表等因素可能会导致增加步骤、减少某些步骤和/或调整组装顺序。此类出版物只有在双方同意的情况下才具有约束力。本文件不涉及纯粹的商业利益，但与安装过程密不可分的事项除外。本文件中的公差基于最佳实践和经验制定，但其他标准也规定了不同的公差。无论本文件何处指定由制造商（或多家制造商）提供文件、图纸或信息，每个制造商均应仅为其自身供应提供适当的信息。 [外文原描述]： The purpose of IEC 63132-3:2020 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.
