Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of hydraulic machinery, and in particular relates to a water turbine runner chamber of a bulb tubular unit. Background technique [0002] The bulb tubular unit has become the main model for the development of low head hydropower resources due to its low applicable water head, large flow rate and high efficiency. The runner chamber of the bulb tubular unit is the key flow-passing component. At present, the runner chamber has a symmetrical structure up and down. The main problem is that the vibration amplitude of the operating condition of the unit is large, and cracks and water leakage in the runner chamber due to vibration are common. Due to the large flow in the runner chamber (a flow rate of hundreds of cubic meters per second), once a problem occurs in the runner chamber, it is very easy to cause a major accident of flooding the factory building. Therefore, it is necessary to design a new type of bulb tu...
