摘要
Abstract
Based on the simulation and analysis of water hammer caused by accidental pump-stop in water supply system,Hammer software is used to simulate the accidental pump-stop water hammer pressure variation of one large-diameter pipe water supply system out-side a power plant under check.Basing on simulation of unprotected measure in accidental pump-stop water hammer,we present three kinds of different protection measures,air valve and butterfly valve at the end pump,surge tower and butterfly valve at the end pump and surge tower and pressure relief valve.The simulation results show surge tower and but-terfly valve at the end pump and surge tower and pressure relief valve can achieve the pur-pose of pipeline protection against water hammer.Taking measures of surge tower and pres-sure relief valve can reduce positive and negative pressure significantly in two large-diameter pipes water supply system when one of them is under check and single pipeline flow is twice as before.关键词
