The experiments indicate that the waterhammer due to separated cavities collapsing at two points can be reduced by intercepting air,or installing elevated-dropped board or,adopting them simultaneously,but the range of pressure reduction and eparation length is distinct.
试验表明 ,泵系统瞬变过程中在两处断流处单独注气 ,或在系统末端仅设置升降式拍门 ,或同时进行注气和拍门操作 ,都可削减两处的断流弥合升压 ,但削减压力的幅度及各处断流的长度不同 :单独采用注气措施对削减系统首端的断流弥合水锤压力最有效 (aA ≈ 0 。
