The equations of critical velocity are derived for horizontal pneumatic transport under three constraint conditions(the mass flux of solid and the pipe diameter,the mass flux of solid and the mass flow ratio of solid to gas,the mass flow ratio of solid to gas and the pipe diameter are respectively set to be constant).
分别建立了三种不同约束条件(给定物料质量流量和输料管管径、给定物料质量流量和输送浓度比、给定输料管管径和输送浓度比)下的水平悬浮气力输送临界风速的基本方程,以克服目前确定临界风速的方法中由于未能给定物料输送能力,而与设计计算相脱节的缺陷。
