摘要: In order to obtain the effect of modification tongue gap on vibration when medium is oil in a double-suction pump.The three-dimensional unsteady numerial method was applied simulate flow with different volute and base circle diameter by using realizable κ-e turbulence model. The distributions pressure velocity pump were obtained gaps hybrid analyzed concept fluctuation. analysis results gave best angle as working which make lowest vibration. And indicated that measure increasing reduce better than angel.
