| titleOfInvention | A kind of axially split type centrifugal multistage pump multiple centrifugal pump transition runner structure |
| abstract | The utility model discloses a kind of axially split type centrifugal multistage pump multiple centrifugal pump transition runner structures, the suction chamber of diffuser pipe, transition runner, next stage impeller including previous stage impeller；Transition runner is connected to the diffuser pipe of previous stage impeller, and transition runner is connected to the suction chamber of next stage impeller；The cross-sectional shape of transition runner is circular ring shape；The material selection roll seamless steel tube of transition runner forms；Previous stage impeller uses double-volute structure；Next stage impeller uses half-helical type suction housing；The cut water of previous stage impeller diffuser pipe is located at the position of previous stage impeller delivery chamber throat；The cut water of next stage impeller suction chamber is located at the middle position of impeller inlet and suction chamber turning point.The utility model using can seperated transition runner convenient for the machining of inner surface and spatial geometric shape reduce the hydraulic loss of transition runner and the generation of vortex, between the high efficient area for improving centrifugal multistage pump multiple centrifugal pump, improve the efficiency of centrifugal pump under off-design behaviour. |
