贯流式水轮机按其结构和布置方式,通常分为灯泡贯流式、竖井贯流式和轴伸贯流式三大类。本文主要介绍国外轴伸贯流式机组。一、国外轴伸式机组概况轴伸贯流式机组由于有较长的主轴穿过尾水管或进水弯管,使整个流道弯曲,从而影响水轮机效率降低,这对于大型机组是不合适的。但对于中、小型机组,特别是小型机组,由于发电机置于流道外,没有特殊要求,故可以采用普通的发电
Tubular turbine according to its structure and layout, are usually divided into bulb tubular, shaft tubular shaft and tubular flow through the three categories. This article mainly introduces the foreign shaft extension tubular unit. First, the overview of foreign shaft extension shaft shaft extension tubular unit due to a longer axis through the draft tube or water inlet pipe, the entire flow channel bending, thus affecting turbine efficiency, which is not suitable for large-scale units . However, for medium and small units, especially small units, because the generator placed in the runner, there are no special requirements, it can be used ordinary power generation
