Until now, there have been a few reports on the damage of the water pumps caused by sand and water cavitation. by use of the test loop for solid and liquid two phases, under the condition of 3 % head drop, the damage location and relative degree of the sand and water cavitaiton occurred on the impeller were tested and researched. the result was, them, compared with the results under the condition that water cavitation occurred and no cavitation but only wear occurred. the differencts were analyzed. the analysis result can be used as the basis of the further research and the improvement of the impeller shape
目前含沙水汽蝕對水泵損傷方面的報導甚少，本文利用固液兩相流試驗臺，對離心泵閉式葉輪在含沙水汽蝕時（ 3揚程下降點）的損傷部位和相對程度進行了試驗研究，並將此結果與清水介質發生汽蝕時的損傷情況[ 13 ]及含沙水無汽蝕情況下的磨損情況[ 7 ]相比較，對其差異進行了分析，為今後進一步探討葉輪損傷機理和葉型改進提供了實驗依據。
