文章摘要: Fire water monitor is one of the main equipment widely used in the fire fighting. A portable fire water monitor with valve-controlled cylinder system was designed. The back and forth movement of the monitor head is controlled by the valve-controlled cylinder system, which is driven by the inlet water pressure. The hydraulic performance of the portable fire water monitor was numerically simulated by using Fluent software. The simulation results show that the outlet velocity is feasible, which is favorable in the jet range. At the same time, the modeling and simulation analysis were carried out for the valve-controlled cylinder system by using AMESim software, the simulation results indicate that this system can self-swing in a particular frequency, and the self-swinging frequency is increasing with the increases of inlet water pressure. Finally, the experiment tests at field verify that the designed fire water monitor can meet the requirements of the jet range, and the self-swinging fre
