摘要
采用了特征线方法对长垣县引黄供水工程事故停泵状态下的水力过渡过程进行研究分析,结果表明原设计不符合要求。结合工程实际情况,建议加大管径或是采取缓闭止回阀和充气阀的工程措施进行水锤防护。
The hydraulic transition process under accident pump suspension in Huanghe river diversion works of Changheng county is analyses with characteristics method.The result indicates that the original design accords not with the demand.The enlargement of caliber, slow closure and aeration valve are proposed for water hammer prevention.
