Abstract

The fluid-induced vibration caused by rotor eccentricity would increase the rotor vibration in the hydroelectric generating set, which would affect the security of rotating machines. The experiment rig is manufactured based on the simplified seal model. The influence of water pumping, water injection and gas injection to fluid-induced vibration in the seal clearance caused by rotor eccentricity is investigated by model experiment. The vibration amplitudes of the rotor with water pumping, water injection and gas injection at different positions and flows are contrasted. The result shows that the fluid-induced vibration in the seal clearance can be suppressed by the anti-swirl flow which has the right position and flow. And the best position and flow of the anti-swirl flow are found. It provides effective experimental basis for using anti-swirl flow technique to suppress the fluid-induced vibration in engineering applications.
