本文在其它学者研究的基础上,通过在四种管径水平管道进行的进一步的高浓度砂浆输送实验研究,认为高浓度尾砂浆属于均质宾汉流体,但在层流状态下水力坡度和管径呈以下关系:用此式推算工业管道的i与u之间的关系时,流速(u)的取值上限为u_(L_2)=u_(L_1)下限为式中的K_1、K_2、u_(L_1)、u_1可通过小管径输送实验确定。 Based on the research of other scholars, this paper studies the further high-concentration mortar transportation in four horizontal pipelines and considers that the high-concentration tailing mortar belongs to homogeneous Bingham fluid. However, under the condition of laminar flow, The relationship between the diameter and the diameter of the pipeline is as follows: When using this formula to calculate the relationship between i and u of the industrial pipeline, the upper limit of the flow velocity (u) is u_ (L_2) = u_ (L_1) and the lower limit is K_1, K_2, u_ L_1), u_1 can be determined by the small diameter delivery experiment.
