摘要:
继文(1) 提出数值方案后, 本文完成了计算程序编制, 并对典型环状给水管网总管及网间管段阀门关闭过程产生的水 力瞬变进行了计算分析。结果表明:阀前阀后管段中的关闭水锤较管网其它管段要大得多;按本文计算所用的阀门特性, 水锤 压力急剧上升时的阀门开度低于2 %, 控制好此后的关闭过程对降低水锤有利;延长给水总管阀门关闭时间有利于降低关闭瞬 间水锤。本文方法具有良好的收敛性, 可用于实际进行工程问题分析。
Abstract:
Based on the numerical solution scheme suggested by author the computer code has been programmed .Hy draulic transient analyses were performed for a typical ring dist ribution w ater supply system under the disturbing caused by the closing valve that is located in w ater supply main and in branch pipe respectively . The results show that the w ater hammers caused by the disturbing have much more ef fect on the pipes near the closing valves than the o ther pipes in netw orks .The w ater hammer is rapidly rising w hen the opening of valve is approaching about 2 percent in the closing process .In order to lower the w ater hammer , i t is necessary that the v alve located in the w ater supply main be very slow ly closed dow n w hen the opening of v alves is approaching 2 percent .The results also show that the method in this paper has good convergence rate and high numerical precision .It is available for performing t ransient hy draulic analysis of w ater supply pipe netw orks in engineering practice .
