摘要： A discharge ring supporting structure of an adjustable-blade axial-flow turbine comprises upper and lower halves separated along a horizontal plane passing through the central axis of the discharge ring. The lower half of the discharge ring is supported by a plurality of supporting columns, each having upper and lower supporting members. The upper supporting members are detachably connected between the lower half of the discharge ring and the lower supporting member. When it is desired to remove the runner, the discharge ring is separated into the upper and lower halves, and the upper supporting members of the supporting columns are removed so that the discharge ring can be lowered. Lowering of the discharge ring allows the runner to be lowered and then removed axially without the runner blades contacting the discharge ring. The upper supporting members of the discharge ring supporting columns are provided with a vibration damper for damping vibration in the discharge ring.
摘要翻译：可调叶片轴流涡轮机的排放环支撑结构包括沿着穿过排出环的中心轴线的水平平面分离的上半部和下半部。排出环的下半部由多个支撑柱支撑，每个支撑柱具有上部和下部支撑构件。上支撑构件可拆卸地连接在排出环的下半部和下支撑构件之间。当需要去除流道时，排出环分离成上半部和下半部，并且支撑柱的上支撑构件被移除，使得排出环可以降低。排放环的下降允许流道下降，然后轴向移除，而流道叶片与排放环接触。排出环支撑柱的上支撑构件设置有用于阻止排出环中的振动的振动阻尼器。

摘要： A water intake portion of a hydraulic machine consists of a casing and a speed ring positioned between the casing and guide vanes for guiding water from the casing to the guide vanes. The speed ring consists of a pair of upper and lower flat members of a ring form, a plurality of stay vanes positioned between the aforesaid pair of members for interconnecting same rigidly, and a reinforcing member of a cylindrical form, which is welded to the top surface of the upper flat member between the inner and outer circumferential edges of the upper flat member. Edges defining therebetween an opening of this casing are welded to the top surface of the upper flat member of a ring form, of the speed ring in the position between the aforesaid reinforcing member and the outer circumferential edge of the upper flat member, as well as to the undersurface of the lower flat member of a ring form, respectively. In this respect, the welding of the reinforcing member of a cylindrical form to the top surface of the upper flat member of a ring form is followed by the welding of the edges of the opening of the casing to the upper and lower flat members of a ring form.
摘要翻译：液压机的进水部分由壳体和位于壳体和导向叶片之间的速度环组成，用于将水从壳体引导到导向叶片。速度环包括一对环形的上下平坦部件，位于上述一对部件之间的多个保持叶片，用于将其刚性地相互连接，以及一个圆柱形的加强件，其被焊接到顶部上平板部件的内周面和外周缘之间的表面。在其间限定该壳体的开口的边缘被焊接到环形的上部平坦构件的上表面，速度环的上表面位于上述加强构件和上部平坦构件的外周边缘之间的位置，以及分别到环形的下平坦构件的下表面。在这方面，将圆柱形加强构件焊接到环形上部平坦构件的顶表面之后，将壳体的开口的边缘焊接到上部和下部平坦构件戒指形式。

摘要： A runner liner of fluid machine which can be attached and detached to and from the runner of the fluid machine without necessitating the disassembling of the latter. The runner liner can be fitted to a groove which is formed in the periphery of the runner, and is divided into a plurality of segments each of which being so sized that it can be brought into the runner chamber through anyone of the fluid passages coming into and out of the runner chamber. The attaching of the runner liner to the periphery of the runner is made by making use of pockets formed in the head cover and the bottom cover which in combination define the runner chamber.
摘要翻译：流体机的流道衬套，其可以与流体机器的流道相连接和分离，而不需要拆卸流体机器。流道衬套可以安装在形成在流道周边的凹槽中，并被分成多个区段，每个区段的大小使得其可以通过任何流体通道进入流道室并从跑道室出来。通过使用形成在头盖和底盖中的凹穴来形成流道衬套附接到流道的周边，这两个口组合形成流道室。
