一、问题的提出“差转速”是卧式螺旋卸料离心机的重要参数之一。它选择的是否得当,不仅关系到机器能否顺利出料,还关系到沉渣内液相含量以及清液中固相含量的多少。从实验或理论分析说明,悬浮液中固相含量多、颗粒尺寸较大时,宜采用较高的差转速。相反,如果悬浮液中固相含量少、颗粒尺寸较小,或希望得到较干的沉渣时,应采用较低的差转速。总之,为了获得好的分离效果,对于不同品种、不同浓度的悬浮液,要选择一个适当的差转速。
First, the issue put forward “poor speed” is one of the important parameters of horizontal screw discharge centrifuge. Whether it is properly selected depends not only on whether the machine can discharge smoothly, but also relates to the liquid content in the sediment and the solid content in the clear liquid. From experimental or theoretical analysis shows that the suspension in the solid content, particle size larger, should adopt a higher differential speed. Conversely, lower differential speeds should be used if there is less solids in the suspension, less particle size, or more dry sediment is desired. In short, in order to obtain a good separation effect, for different species, different concentrations of suspension, to choose a suitable differential speed.
