Abstract
用于叶轮的叶片,所述叶轮用于叶轮发电站。这种特殊结构的叶片可以保证,在叶片后面产生较小的涡流,并以此来提高冲击水流的利用率。
Description
技术领域
本发明涉及一种符合权利要求1前序部分的用于叶轮的叶片。
背景技术
在当今技术发展状况下,用于叶轮的叶片通常采取一体的、连续的实施方式。使用这种通行的、封闭式的叶片结构,会在叶片的背面产生干扰涡流。
发明内容
本发明的任务是,为叶轮配备能改善叶片背面干扰涡流状况的叶片。
该任务通过本发明借助开篇时提到的叶片如此完成,即叶片包括至少两个元件。
在本发明的优选实施方式中,所述元件通过中间空间分开,和/或布置成叠片形式。
本发明的另外的优点在于,所述元件是错位安装的。
在本发明的优选实施方式中,所述元件在迎流方向上具有弧度,并且在流出方向上伸展开。所述弧度可以是凸起的,也可以是凹陷的。
本发明进一步的优点在于,所述元件相互间具有角度。
元件与假想的轴线叶轮的角度由内向外变大,这是有利的。
在优选的实施方式中,元件之间的距离大小可以相等。
附图说明
本发明所具备的优点可以通过不仅局限于此的在附图中示出的结构示例进一步详细阐述。
示例示出:
图1叶轮的横截面示意图,其配有由现有技术已知的叶片;
图2符合本发明的元件的横截面示意图;
图3叶轮的横截面示意图,其配有由符合本发明的元件构成的叶片;
图4叶轮的横截面示意图,其具有由符合本发明的元件构成的叶片和假想中线;
图5备选叶轮的横截面示意图,其配有由符合本发明的元件构成的叶片。
具体实施方式
图1是已知实施方式的叶轮(3)的截面示意图,按图1叶轮(3)包括至少一个叶片(1)和一个轮毂(2)。
在图2的示意图中示出了符合本发明的元件(4)的斜视图,一个在迎流方向,另一个在流出方向。图中还注明了水(5)的流动方向和叶轮(6)的旋转方向。元件(4)可以在其和水接触的侧面上具有弧度,并且向轮毂(2)或向元件(4)的里端方向伸展开或者可以是直的。如果弧度是凸起或凹陷时,则是特别有利的。
图3示出的是本发明的一种特殊的实施方式。多个由元件(4)构成的叶片(1)安装在叶轮(3)上,由于整个叶片(1)围绕叶轮(3)的轮毂(2)旋转,使得元件(4)相对水流的位置持续改变。在叶片(1)浸入时(元件(4)一个接着一个)最外部的元件(4)处在水流阻力很小的位置。随着叶片(1)的继续转动,里面的下一个元件(4)也浸入水流。在处于和水流垂直的位置时,元件(4)所起作用几乎相当于只由一个零件所构成的叶片(1)那样。当符合本发明的叶片(1)处于其它位置时,水流可以通过中间空间流过。这个中间空间表明了叠片式或者条板式叶片(1)的特性。叶片(1)背面的干扰涡流得到降低,并且叶轮(3)的运转阻力也得到减小。这种由多个元件构成的叶片(1)或假想的中线(7)即可以是弯曲的,也可以是直的。
在符合本发明的实施方式中,如图4所示,配有由元件(4)所制成的叶片(1)的叶轮(3)可以从两个方向(5)迎流,根据水流强度,有必要将叶片(1)在水流方向上构造成敞开式或者封闭式。
图5示出的是本发明的特别有效的实施方式。一体的叶片(1)的纵向截面具有中线(7)。这个中线(7)应和叶片(1)的弧度相应。至少两个根据本发明的元件(4)在假象中线(7)上如此布置,使得假想中线(7)和第一元件(4)之间的夹角小于假想中线(7)和第二元件(4)之间的夹角。元件(4)和中线(7)的交点可以在中线(7)上具有彼此相等的距离。在一种变型实施方式中,上述距离也可以不同。在特别有效的实施方式中,元件(4)的大小可以不同。元件(4)可以从外向内变小。由此也会造成元件(4)之间的距离也不同。当上述距离从外向内变小时是特别有效的。
