摘要
针对曹妃甸工业区供水工程管线长、沿线地面高程变化大、管道爆管后损失严重的特点,分析事故停泵后备用泵投入运行和全部机组停机后的启动过渡过程中水力要素的变化幅度及对管道压力的影响,分析管道压力过大的原因,并采取相应的解决措施,确保管道安全运行。
This article countered the features of long pipeline,large elevation change along the ground and serious loss after the pipeline loss of the water supply engineering in Caofeidian Industry Zone,analysing the amplitude of hydraulic elements and the effects to pipeline pressure when the standby pump put into operation after accident and the process of starting the transition process after all the unit shutdown,as well as the cause of excessive pressure for pipeline,and take relevant solutions to ensure the safe operation of the pipeline.
