两种水力过渡计算模型的水锤防护比较

Water Hammer Protection Comparison of Two Kinds of Hydraulic Transient Calculation Model

断流弥合水锤对于长距离的大型输水管道来说危害极大,水锤升压是普通水锤的数十倍。目前主要通过水力计算模型来预测管道压力情况,主要存在两种模型,其区别在于是否反应出断流现象及计算出断流后的压力。通过理论结合实践得出结论,考虑断流弥合水锤的计算模型更反映出实际情况。

Water hammer of cavities collapsing is harm for long distance and large water pipeline,water hammer boost is dozens of times more than the ordinary water hammer. At present mainly through hydraulic calculation model to predict the pipeline pressure, there are two kinds of models, the difference is that whether can reflect the flow and calculate pressure. By combining theory and practice conclusion, consider the water hammer of cavities collapsing model reflects the actual situation.
