| 摘 要： | 对新型铁路上水设备进行了试验，绘制了给水管、上水设备、水箱注水口和上水管出水口之间位能水头、压力水头和流速水头转化关系的总水头线；经分析得出上水系统水头损失主要是由上水设备引起的，而上水软管缠绕又是其中主要的影响因素；分析了产生水头损失的部件及原因，并提出了在设计、设备制造和运行中减少水头损失、提高上水流量的途径和措施。

| Abstract: | Based on the test of the new-type railway water supply equipment,the total head line was drawn in order to describe the conversion relationship of elevation head,pressure head and velocity among hydrant,water supply equipment,filling pipe end and water pipe orifice.The head loss of water supply system was mainly caused by water supply equipment,and the coiled water hose was the main factor.Based on the analysis of components which caused the head loss and the reason why this happened,the measures to reduce ... |
