Description

消减导流叶片周围磨损的方法与装置
技术领域
本发明涉及一种消减导流叶片周围磨损的方法,尤其涉及一种消减由于驱动水中的微粒导致的导流叶片周围磨损的方法,导流叶片安装在水轮机中。本发明也包括一种实现此方法的装置。
背景技术
本发明中提到的驱动水是指一种流经水轮机并通过压降在水轮机中转送能量的水。
水轮机暴露于流经涡轮的水中而被磨损,在水轮机中输入河水时的磨损比输入水库里的水时的磨损要严重的多,因为河水中含有大量的沙子。
虽然所有种类的水轮机中或多或少都存在磨损问题,但法式水轮机尤其明显,法式水轮机经常被设计为在转缸式发动机和固定件之间的密封件上设置相当小的狭缝。
目前也已经证明,相当大的磨损可能发生在固定互联组件之间的连接点上。即使比较小的磨损在流路或密封件上也会导致附属物相当大的震荡和水的泄露,从而降低效率。
发明内容
本发明的目的在于补救或降低至少一个现有技术存在的缺点。
这个目的可以通过本发明下面的描述和后面的权利要求中公开的特征获得。
本发明提供了一种消减由于驱动水中的微粒导致的导流叶片周围磨损的方法,导流叶片安装在水轮机上的导流叶片壳体中,这种方法的特征在于包括:
-设置一条给水通路,使比驱动水干净的水经给水通路流向导流叶片和导流叶片壳体之间的连接区域;以及
一引导比驱动水干净的水流过狭缝,其中狭缝至少部分环绕导流叶片。
通过提供更干净的水到导流叶片的周围区域,洁净水可以占据导流叶片的周围区域,从而使含有微粒的驱动水较小程度地接触到导流叶片暴露的区域。
这种方法可以借助一种消减由于驱动水中的微粒导致的导流叶片周围磨损的装置来实现,导流叶片安装在水轮机上的导流叶片壳体中,该装置的特征在于设置有一条使比驱动水干净的水输送到至少部分环绕导流叶片的狭缝中的给水通路。
狭缝可以包括在导流风叶轴和导流风叶壳体或导流风叶轴和导流风叶轴套之间的环状结构。
狭缝特别容易被驱动水中的颗粒磨损,经验显示导流风叶和导流风叶壳体之间的磨损可能导致相当大的效率降低,另外还可能出现的问题是切断水轮机中水的流动。
给水通路可以设置在导流风叶或导流风叶壳体上。
按照本发明的方法和装置可以保护反动式涡轮机的主要部件避免遭受不纯的驱动水的磨损,以及可以延长组件的使用寿命。
附图说明
下文中结合附图描述了一个优选的实施方案,其中:
图1为一种设置有本发明的给水通路的水轮机的截面图;及
图2为从图1中提取的局部放大图。
具体实施方式
附图中参考数字1表示一种现有的水轮机的实施例,其包括涡轮机壳体2和流道4。
涡轮机壳体2与环绕流道4的导流装置6装配在一起;座环8和螺旋滚筒10环绕导流装置6。涡轮机壳体2的出口与吸水管12相连。
导流装置6除了包括导流叶片壳体14之外,还包括多个分布在导流装置6上的导流叶片16。导流叶片16的制动器图中没有显示。
导流叶片壳体14是上盖17a和下盖17b的一部分。
导流叶片16交替地安装在纵轴上,以便能够控制驱动水流经水轮机1。
参见图2,导流叶片16包括连接轮毂22的上轴20,和下轴24。轮毂22连接图中未显示的导流叶片制动器。
轴20、24密封设置在导流叶片壳体14的轴承26中。在导流叶片壳体14和导流叶片16之间的环状结构以狭缝28的形式形成在每一个轴20、24上。
内孔30贯穿下轴24,并延伸到导流叶片16中。横向孔32从内孔30延伸到每一个狭缝28。
供水管34与内孔30相连,并与内孔30、横向孔32一起形成给水通路36。
在水轮机1运行过程中,比驱动水干净的水在适当的压力下通过给水通路36被引到狭缝28中,也就是,通过供水管34、内孔30和横向孔32。
干净的水流过狭缝28进入导流装置6中,由此含有微粒的驱动水基本上被阻止渗透到狭缝28中。
在另一实施例中,导流叶片壳体14可以被设计为在导流叶片壳体14和导流叶片16之间设置导流叶片轴套38,由此狭缝28便位于导流叶片16和导流叶片轴套38之间。
洁净水例如可以是来自与驱动水同一水源中的比较干净的水,或者是来自与驱动水不同的水源。
