Hydraulic machine, particularly water turbine, pumping turbine or pump, has impeller with multiple blades, spiral housing surrounding impeller and traverse ring

摘要

The hydraulic machine has an impeller with multiple blades, a spiral housing (3) surrounding the impeller and a traverse ring. The traverse ring has two traverse ring shrouds (4.1,4.2), which are connected to each other by tie rods. The regions of circumferential edges are configured and disposed so that both extend parallel to the axis of rotation of the impeller, or form an angle of not more than 11 degrees.
