    • PURPOSE:To prevent vibration by providing individually a plurality of guide vanes capable of opening and closing to adjust the opening of the guide vane such that the downstream side of sectional area of flow path varying with the opening and closing amount of these vanes is always smaller than the upstream side. CONSTITUTION:A normal guide vane 6 is provided intermediately between upper and lower water path walls 7, 8 and a guide vane 12 provided near the wall 8 to be respectively supported by individual rotary shafts 13, 14 while being drivably opened and closed by a drive mechanism. Also, the guide vane 12 is provided with a curved surface 15 smoothly contacting a curved surface 8' of the wall 8 and the other surface 16 contacting a wall portion 8'' at the runner 2 side so that the extensions of these both surfaces intersect with each other near the runner to form the downstream end 17. And when both guide vanes are rotated counterclockwise, the min. sectional area portion of flow path at the lower side water path 9' provides the downstream end 17 in the same way as in the full opened time so that passing water stream provides a reduced one with small head loss and cavitation hardly occurs.

    • PURPOSE:To obtain a simple and compact water turbine, by providing movable vanes integrally formed with each other, and supporting in a casing a rotor having a liquid removing passage bored at a center of the movable vanes, whereby the rotor is rotated by pressurized liquid injected from nozzles provided on a peripheral surface of the casing. CONSTITUTION:Four vanes 10 are radially arranged, and both ends of the vanes 10 are connected by a disc 11. A rotor 2 having a liquid removing passage 4 bored at an axial center thereof by passing through the disc 11 at its one end is rotatably supported in an inner casing 5 having nozzles 6 on its peripheral surface. Further, an outer casing 7 having a liquid induction port 9 is formed around the inner casing 5 in such a manner that a pressure chamber 8 is defined between the inner casing 5 and the outer casing 7 to form a water turbine. In the case that the water turbine is used as a pipe washing device 17, an attachment 21 for a brush 20 is mounted to an end of the liquid removing passage 4, and is rotated with the rotor 2 by pressurzed liquid injectied from the nozzles 6.
    • 目的:为了获得简单紧凑的水轮机,通过提供一体形成的可动叶片,并且在壳体中支撑具有在可动叶片中心钻孔的液体移除通道的转子,由此转子由加压液体 从设置在壳体的外周面上的喷嘴喷射。 构成:四个叶片10径向布置,叶片10的两端通过盘11连接。具有在其轴向中心穿过其一端的盘11的液体去除通道4的转子2可旋转 支撑在其外壳表面上具有喷嘴6的内壳5中。 此外,具有液体导入口9的外壳7形成在内壳5的周围,使得在内壳5和外壳7之间形成有压力室8,以形成水轮机。 在水轮机用作管道清洗装置17的情况下,将刷子20的安装件21安装在液体移除通道4的端部,并且通过从喷嘴6喷射的加压液体与转子2一起旋转 。
