Abstract

The invention discloses a water distribution ring pipe, which belongs to the technical field of fluid mechanical engineering equipment, comprises a water distribution ring pipe upper section and a water distribution ring pipe lower section which are connected to form a ring pipe body, and is characterized by further comprising a runner chamber and an angle adjusting ring, a first fixing base is fixed to the top of the annular pipe body, a second fixing base is fixed to the bottom of the annular pipe body, the first fixing base and the second fixing base are both located at the joint of the annular pipe body and the branch pipe, a branch pipe splitter plate is embedded between the first fixing base and the second fixing base, the cross section of the branch pipe splitter plate is in a tapered wedge shape, and a transition flange is arranged on the runner chamber. The transition flange and the runner chamber are connected through an angle adjusting ring. By replacing the branch pipe splitter plate, a hydraulic flow channel can be rapidly changed, the jet flow angle is adjusted, rotating wheels with different pitch circle sizes are replaced for testing, and the model testing convenience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of fluid mechanical engineering equipment, in particular to a water distribution loop. Background technique [0002] The impact turbine is a hydraulic machine that uses high-speed water flow to impinge the runner to do work. The water distribution ring mainly plays the role of guiding the incoming flow. The quality of the outflow, which in turn affects the performance of the unit. At present, the bifurcated pipe manifolds of the water distribution ring are designed in the process of processing the water distribution ring and cannot be replaced, resulting in the inability of the bifurcated manifolds to compare their functions from the test point of view. [0003] The publication number is CN102513960A, and the Chinese patent document whose publication date is June 27, 2012 discloses a method for installing a water distribution ring pipe of an impingement type water turbine, which is characterized in that it ...
