Abstract

一种丝状涡轮，包括喷嘴，壳体和转子，所述转子叶片为丝状，丝状叶片可以相互平行呈多层鸟笼状，也可纵横交错呈三维网状。转子轴中空并开有排气孔。这种丝状涡轮用丝状叶片取代传统特斯拉涡轮的薄圆盘，由于丝状叶片固定在两个厚圆盘上，所以比薄圆盘刚度好，不易变形，使转子可以做得直径更大而不易变形。丝状叶片形成的丝网结构还可对喷嘴气流具有一定的消音效果，降低机器噪音。

Description

一种丝状涡轮
所属技术领域
本发明涉及一种丝状涡轮，属汽轮机技术领域。
背景技术
特斯拉涡轮又称无叶涡轮，其形状是一根轴上按一定间距固定有多个光滑且薄的圆盘，气流从切线方向冲击这些圆盘，利用边界层效应带动这些圆盘和轴一起转动。该涡轮虽然具有结构简单、体积紧凑、效率高、成本低等优点，但因为圆盘尺寸大时刚度不够易变形，导致盘间涡流挠动大，振动大等缺点而未能普及应用。
发明内容
为克服现有技术的不足，本发明提供一种丝状涡轮，该丝状涡轮包括喷嘴，壳体和转子，所述转子叶片为丝状，一般为金属丝，丝状叶片固定于两个圆盘之间，丝状叶片可以相互平行呈多层鸟笼状，也可纵横交错呈三维网状。转子轴中空并开有排气孔。喷嘴沿切线方向向转子喷气，气流会在壳体内侧的导向作用下形成涡流，由于布满转子的丝状叶片大大增加了转子与气流的接触面，根据边界层效应，转子将被气流带动一起旋转，从而实现转子的转动。这种丝状涡轮用丝状叶片取代传统特斯拉涡轮的薄圆盘，由于丝状叶片固定在两个厚圆盘上，所以比薄圆盘刚度好，不易变形，使转子可以做得直径更大而不易变形。丝状叶片形成的丝网结构还可对喷嘴气流具有一定的消音效果，降低机器噪音。
本发明的有益效果是，可以使涡轮的尺寸做大，从而功率加大且运行更平稳可靠，噪音降低。
附图说明
图1是本发明的结构示意图。
图2是本发明的剖视图。
图中1.喷嘴，2.壳体，3.固定盘，4.丝状叶片，5.排气口，6.排气孔，7.转子轴。
具体实施方式
在图中，壳体(2)上有喷嘴(1)，壳体(2)内有转子，转子由固定盘(3)和固定于固定盘(3)之间的丝状叶片(4)构成，转子轴(7)中空并开有排气孔(6)联通到排气口(5)。
工作时气体由喷嘴(1)，喷入壳体(2)内，气流会在壳体(2)内侧的导向作用下形成涡流，由于固定盘(3)之间布满丝状叶片(4)大大增加了转子与气流的接触面，根据边界层效应，转子将被气流带动一起旋转，从而实现转子的转动，做完功的泛气由转子轴(7)上的排气孔(6)通到排气口(5)排出。
