英文摘要： Fire water monitor is one of the major equipment in fire fighting. Its hydraulic performance and basic structural parameters are key factors that affecting fire fighting. On the basis of the designed fire water monitors, the relationships between the main structural parameters and hydraulic performance parameters of fire water monitor are analyzed, and its influencing rules on flow range are also discussed. The relationships between channel geometries of monitor body and jet performance are simulated and tested.At the same time, through the theoretical calculation, flow simulation and experimental analysis on the key component nozzle, the suitable channel geometries of monitor body and nozzle structural parameters are obtained. These research results can provide the theoretical and experimental references to the design of fire water monitor, and it is also an important theoretical basis of fire fighting equipment update in domestic.
