摘要
借助稳定流动液体连续性方程等理论 ,导出阀芯移动量S与节流面积f的关系 ;通过正交试验 ,选出喷头最佳的喷孔直径和长度 ,研制出适用于不同水压及相配套设备中的多功能喷头 .并与同类产品进行试验比较 ,其喷射距离要远 4.1m(万得凯好帮手系列喷头为 4.2m) ;与QL - 2 98型手提式高压清洗机的喷头 ( 9m)相比 ,要远 1m .
According to theory of the fluid mechanics,for example,the continuous equation of flowing stable fluid and so on,the multifunctional nozzle to be used for different hydraulic source of water was developed.We established a relationship between the quantity of moving nozzle rod and the throttling area of the nozzle.The optimum spout diameter and length of the nozzle from the test of the nozzle are selected by the orthogonal test.Therefore,the nozzle was tested and compared with the nozzle of the same kind.The spurt distance is (4.1m) farther than the nozzle of the same kind(4.2m).A method for designing the nozzle is provided.
