GB/T 43683.3-2025 Guidance for installation procedures and tolerances of hydroelectric machines—Part 3:Vertical Francis turbines or pump-turbines
Abstract
This document provides the general installation procedures and tolerance requirements for vertical mixed-flow turbines or pump-turbines. There are many methods of installing the unit, and this document introduces a common installation process. In this document, "turbine" refers to vertical mixed-flow turbines or pump-turbines. The dimensions of the unit components, the design of the unit, the layout of the power station, or the delivery time of the components may result in the addition of extra steps, the elimination of certain steps, and/or changes in the installation sequence.
This document is only binding if both parties agree to it.
This document is not applicable to purely commercial purposes, unless it is inextricably linked to the installation of the unit.
The tolerances specified in different standards may vary. The tolerances in this document are determined based on general practices and experience.
Regardless of whether this document stipulates that the manufacturer should provide documents, drawings, or information, each manufacturer shall provide the necessary relevant materials for the equipment they supply.
