水轮机安装程序和公差指南第4部分:立式轴流转桨式水轮机

[中文适用范围]： 本文档的目的在于以一般方式确立垂直卡普兰式或轴流式水轮机安装时的合适程序及公差。本文件展示了一种典型的装配方式，当本文件中提到“水轮机”时，均指垂直卡普兰式或轴流式水轮机。机组的装配方式有多种。机器的尺寸、机器的设计、发电厂的布置或部件的交货计划等要素可能会导致增加步骤、消除某些步骤和/或装配顺序的变化。应理解，此类出版物仅在缔约双方同意且仅在其同意的范围内具有约束力。本文件排除了纯商业利益事项，除非这些事项与安装作业密不可分。本文件中规定的公差是基于最佳实践和经验建立的，尽管承认其他标准规定了不同的公差。 wherever 本文件规定由制造商（或制造商）提供文件、图纸或信息时，每位制造商仅提供其自身供应的相应信息。 [外文原描述]： The purpose of IEC 63132-4:2020 is to establish, in a general way, suitable procedures and tolerances for the installation of a vertical Kaplan or propeller turbine. This document presents a typical assembly and whenever the word “turbine” is used in this document, it refers to a vertical Kaplan or propeller 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.
