| 摘 要： | 通过分析水平气力输送系统悬挂式电子称量装置的固体物料输送量记录曲线，判定了输送状态的稳定性，进而提出了中累颗粒（ｄｓ≤０．５ｍｍ），高混合比（μｓ＝３０－１５０），水平低速（ｕｇ＜１５ｍ／ｓ）输送临界速度的经验关联式。

| Abstract: | Instability of horizontal pneumatic conveying system was recognized through analyzing the wave of solid mass flowrate and pressure fluctuation during transportation of solids. Furthermore, an empirical correlation for critical conveying velocity of fine and medium size particles (ds<0.5mm) under high solids loading (range from 30 to 150) at low gas velocities less than 15m / s was proposed. |

| Keywords: | critical velocity pneumatic conveying instability low velocity horizontal pipe / dense-phase |
