一种灯泡贯流式机组水轮机转轮室
摘要：
本发明属于水力机械技术领域，具体涉及一种灯泡贯流式机组水轮机转轮室。该转轮室包括筒状体，所述筒状体上下平分为半筒状的上分瓣轮室和下分瓣轮室，所述上分瓣轮室和下分瓣轮室通过法兰连接，所述上分瓣轮室沿轴向平分为左分瓣轮室和右分瓣轮室，所述左分瓣轮室和右分瓣轮室通过法兰连接。所述转轮室减小了机组运行工况的振动，提高了结构刚度，因而其结构可靠性高，减少了裂纹和漏水问题，能有效保证机组安全稳定运行；而且无需专门设置纵向加强筋以提高结构刚度，从而减少了材料用量，提高了材料利用率；不但安装方便、灵活，而且安装时能够实现对转轮室间隙的精细化调整。
摘要（英）：

The invention belongs to the technical field of hydraulic machinery, and particularly relates to a water turbine runner chamber of a light bulb tubular unit. The runner chamber comprises a barrel-shaped body, wherein the barrel-shaped body is equally divided into an upper semi-barrel-shaped sectioning runner chamber and a lower semi-barrel-shaped sectioning runner chamber in the vertical direction; the upper sectioning runner chamber and the lower sectioning runner chamber are connected through a flange; the upper sectioning runner chamber is equally divided into a left sectioning runner chamber and a right sectioning runner chamber in the axial direction; and the left sectioning runner chamber and the right sectioning runner chamber are connected through a flange. The runner chamber reduces vibration of a unit operation working condition and improves structural rigidity, so that structural reliability of the unit is high, cracks and water leakage problems are reduced, and the unit can be effectively guaranteed to safely and stably operate; a longitudinal reinforcing rib does not to specially arrange to improve the structural strength, so that material dose is reduced and a material utilization rate is increased; and moreover, the runner chamber is convenient and flexible to mount, and can realize fine regulation on a runner chamber gap during mounting.
