喷嘴位置 meaning in English
nozzle location
Examples
- Nozzles of jacket on agitated vessels , of glass lined steel - position of nozzles
钢制搪玻璃搅拌容器用套管喷嘴.喷嘴位置 - 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。
