driven nozzle meaning in English
高压远射程喷嘴
Examples
- A reasonable position of driving nozzle helps to achieve the maximum material flow that also depends on other parameters such as backpressure , properties of conveyed material and driving gas . it is observed that , an increase of convergent section angle is harmful to the pneumatic conveying system , and also influences on the mass flow rate of conveyed material , the distribution of static pressures in injector and the pressure drops of conveying pipe . in addition , within a reasonable scope of air mass rate , increasing the driving jet velocity is more advantageous than enlarging the dimension of driving nozzle
试验研究发现,气体喷嘴位置对气固喷射器的输送能力影响最大,气体喷嘴存在某一最佳位置,而这一最佳位置与背压、输送物料特性和输送风特性相关联;气固喷射器的收缩角对其输送能力、内部静压分布和输送管阻力特性均有适量影响,收缩角增大对整个输送系统均不利;在适当的输送风范围内,提高气体喷嘴出口速度比扩大气体喷嘴尺寸更为有利,但气体喷嘴出口速度过高会增加气固喷射器和输送管内的能量损耗,给输送带来不利的影响;系统背压与气固喷射器的气体喷嘴出口速度的选取有关。
