Abstract

The hydraulic induced radial force of the single blade centrifugal pump effects its running stability seriously. To exploreresearch the hydraulic induced radial force of the single blade centrifugal pump, a single blade centrifugal pump was chose as the experimental object. With a hydraulic machinery comprehensive tester and hall sensors, the hydraulic induced radial force was obtained by measuring the pump’s radial force under closed condition and pumping condition. The results show that the radial force of different type blade has a similar trend. When the pump is under closed condition, the distribution map is approximately circular, and the magnitude of the radial force is basically unchanged. However, when while it pumping, the distribution of hydraulic induced radial force becomes distorted oval, and the impeller location difference between the maximum value and the minimum value is about 180 °. Especially, when the trailing edge is close to the volute outlet, the induced radial force becomes smaller and disordered. On the contrary, when the trailing edge rotates is near the bottom of the pump, the induced radial force reaches the maximum and gradually stabilizes. It was shown that the hydraulic induced radial force of the single blade centrifugal pump increases with the increase of flow rates, and the radial force changed changs violently under small flow rate, while it becomes stable under designed and high flow rates.
