对粉体液力输送中输送压降与输送速度的设计计算方法进行了综述 ,包括可沉降的悬浮液输送和非沉降的浆液输送两方面。可沉降的悬浮液输送包括了均化悬浮、非均化悬浮、滑动沉积层和固定沉积层等 4类 ;非沉降的浆液输送包括了纯粘性浆液、粘弹性浆液及依时性浆液等 3类。
The design and calculation methods of conveying pressure drop and conveying speed in powder hydraulic conveying are reviewed, including both sedibletable slurry transport and non-sedimentation slurry transport. Sedimentable suspensions can be transported in four categories: homogenized suspension, non-homogenous suspension, sliding sediment and fixed sediment. Non-sediment slurry transport includes three types of viscous slurry, viscoelastic slurry and time-dependent slurry .
