Abstract

PURPOSE:To finish the path smoothly by forming a relatively long inlet side guide vane as a release vane integrally with the inner tube of inlet side guide vane body while forming a relatively short delivery side guide vane as a choking vane between the outer tube of guide vane body and the delivery side inner tube. CONSTITUTION:Since the inner tube of a guide vane body 10 is splitted into the inlet side guide vane body inner tube 13 and the delivery side guide vane inner tube 12 in the direction perpendicular against the longitudinal direction of the spindle while relatively long inlet side guide vane 15 is formed as an open vane integrally with the inner tube 13, the portion of the inlet side guide vane 15 can be finished smoothly by means of a grinder. While since the delivery side guide vane 14 formed integrally as a choke vane between the guide vane body outer tube 11 and the delivery side guide vane body inner tube 12 is relatively short, said portion can be finished smoothly by means of a grinder. Since the entire region of path can be finished smoothly, the flow loss is reduced and the efficiency of the centrifugal hydraulic machine can be improved.

By the way, as shown in FIG. 4, by rotationally driving the main shaft 5, a flow C is discharged from the impeller 6 at an angle α with respect to the tangential direction of the outer circumference of the impeller. This flow -C is divided into a circumferential component Cu and a meridional component CII+. In a low specific speed mixed flow pump or the like, the meridional component CmLi is very small compared to the circumferential component Cu, and if the kinetic energy of the circumferential component Cu can be efficiently converted into pressure energy, high pump efficiency can be obtained. For this reason, it is desirable that the passageway (diffuser) formed by being surrounded by the guide blade cylinder outer cylinder 2, the guide blade cylinder inner cylinder 3, and the guide blades 4 has a curved shape as long as possible. Therefore, as shown in FIG. 4 developed using error trigonometry, the guide vane 4 has a small entrance angle βi.
By making the turning angle Δβ (Δβ=β0−βi) very large,
It is configured to be wrapped in a long curved shape.

(Problems to be Solved by the Invention) The guide vane body of the conventional centrifugal fluid machine described above is formed by integral casting, and the passageway has a narrow and long curved shape. It is very difficult to remove the sand. Further, it is almost impossible to finish the inner surface of the water passageway smoothly using a grinder L or the like. For this reason, the inner surface of the passageway, which is the water surface, is rough, and the flow within this passageway suffers a large loss due to tooth wear. There was a problem in that the pump efficiency decreased due to this loss. Furthermore, it is difficult to inspect the inner surface of the water passage.

(Function) The guide vane cylinder is divided into an inlet side guide vane cylinder and a discharge side guide vane cylinder in a direction perpendicular to the longitudinal direction of the main shaft. Since the long inlet guide vane is integrally formed as an open vane, the passageway in the part of the inlet guide vane can be sufficiently smoothed with a grinder or the like. Further, the relatively short discharge-side guide vanes are formed of closed vanes, and because they are short, the passageway in the discharge-side guide vanes can be sufficiently smoothed with a grinder or the like. As a result, the entire area of the water passage can be finished smoothly, and efficiency can be improved.
