【摘要】 针对长距离供水系统的特点,运用水锤理论和特征线方法,对不同管路系统进行水锤防护计算分析,并以广东省大亚湾供水系统为对象,重点对采用空气阀作为事故停泵水力过渡过程防护的可行性进行了分析与论证.计算结果表明,在特定条件下空气阀也能较好地抑制液柱分离的发生并有效地进行水锤防护.更多还原

【Abstract】 In accordance with the characteristics of different long water supply systems,calculations and analyses are carried out for the transient process caused by accidental pump-stop based on the theory of water hammer and the method of characteristics. Emphasis is put on the feasibility of utilizing air valves as water hammer protective measures. The simulating results show that air valves may be used to suppress the occurrence of water column separation and to protect pumping systems effectively under certain special conditions.更多还原
