cavitation condition meaning in English

空化状态

Check pressure drop ( inlet - outlet ) to insure that desired outlet pressure is above the recommended lowest outlet setting to avoid cavitation conditions
止回压降（进口-出口）确保所需的出口压力处于推荐的最低出口设置点上，以避免空穴现象发生。
The analysis results indicate that the transient performance of pump during starting period decreases evidently under cavitation condition ; cavitation performance of the pump has close relationship with flowrate , rotational speed and impeller parameters
分析结果表明，启动过程中的汽蚀现象使混流泵瞬态性能迅速下降，汽蚀性能与流量、转速、叶轮参数等有密切关系。
( 2 ) retrofitted the small turbine of tai pin shao hydropower station in this paper . the results indicated that given the unchanged channels of the original runner hl240 - lj - 120 and satisfied cavitation condition and stability requirement , the electricity generated by the turbine generator increased from 3000kw to 3600kw when the design head was 36 . 2m , which arrived at the expectant objective
( 2 )对太平哨电厂的小机进行了改造，在不改变原hl240 - lj - 120流道并满足气蚀和稳定性要求，在设计水头为36 . 2米时，水轮机发电机出力由原来的3000千瓦增容到3600万千瓦，达到了预期目标。
