摘要
流体流经弯曲管道时的管流水头损失是影响弯曲流道消防炮效率或射程的主要因素之一。在流体动力学理论分析基础上,利用直型流道代替弯曲流道技术,介绍了一种两自由度混联结构消防炮的开发设计。实验结果证明,设计达到了预期目标,对大射程、高效率、低能耗消防炮的开发研究具有指导意义。
The head loss in pipe flow when fluid goes through bend flow channel is one of the main factors leading to serial mechanism fire-monitors’pressure drop and short-distance jet.The design of a fire-monitor with 2 degrees of freedom compound mechanism,which realizes the substitution of the traditional bend flow channel(BFC)with a straight one(SFC)based on the analysis of fluid dynamics theory,is presented in this paper.The expected results of the work were achieved based on the experimental results,which has guidance for the redevelopment of novel fire-monitor with longer distance,higher efficiency and lower energy consumption than traditional one.
