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。 On the new railway water equipment were tested, drawn the water pipe, water equipment, water tank water inlet and water outlet pipe between the bit head, pressure head and flow head conversion relationship between the head line; Water head loss is mainly caused by the water equipment, and the water hose winding is one of the main influencing factors; Analysis of the head loss of the components and causes, and proposed in the design, equipment manufacturing and operation to reduce the head Loss and improve the flow of water ways and measures.
