| Abstract: | The cavitations reason and reformation methods were systematically summarized.The special function of introducer to improve the impellor's cavitation was analyzed and the structure and performance matching between impellor and introducer were researched.The comparative analyses among impellor with one lever introducer,two lever introducers,three introducers were performed.These fully demonstrate the introducer's affection to improve impellor pump cavitation. |
