Abstract
PURPOSE:To prevent the burble of a liquid and improve the pump efficiency by a mechanism wherein an annular section is provided between the outward flow passage and the inward flow passage in the passage of being liquid discharged from the runner in parallel with the axis where two curved flows may be performed at the separate zones respectively. CONSTITUTION:An annular section 14 is provided between the outward flow passage 10 and the inward flow passage 11 in the liquid passage discharged from the runner 2 in a parallel with the axis. The length of the annular passsge 14 may be 0.1-0.7 of the length of the guide blade 4 meridian on the average passage, which is necessary to divide into two inward and outward curved zones. Accordingly, since the fluid supplied from the runner 2 is developing the annular passage 14 in a parallel to the axis before the passage is inwarded, which develops curved flow only within the annular surface at the zone A, and develops curved flow only within the meridian surface at the zone B, two directional curves being developed at the separate zone, and the burble of the fluid is prevented to improve the pump efficiency.
