在对某铀水冶厂尾矿(r_s=2.65,+60目占7.08％;-200目占61.59％)进行的环形浆体管道输送试验中,考虑到实际工程中水平管段甚少,而倾斜管段很多,所以在对水平管段(两种管径Dg70、Dg50各一条)的沿程损失进行量测的同时,对两个倾斜管段(Dg70,上坡,θ=30°;Dg50,下坡,θ=30°)也进行了沿程损失量测。量测是用清水比压计进行的。量测装置见图1,主要设备为一清水比压计。在管道测压孔出口处加设了有机玻璃制成的隔离罐,防止试验管道中的浆体进入比压计。
In the annular slurry pipeline transportation test for the tailing of a uranium water mill (r_s = 2.65, + 60 mesh, 7.08%; - 200 mesh, 61.59%), taking into account that there are few horizontal pipe sections in the actual project, Therefore, when measuring the loss along the horizontal section (one of two diameters Dg70 and Dg50), the two inclined sections (Dg70, uphill, θ = 30 °, Dg50, downhill, θ = 30 °) also measured the loss along the way. Measurement is carried out with a water meter. Measuring device shown in Figure 1, the main equipment for a water meter. An additional isolation tank made of plexiglass is added at the outlet of the pipe piezometric hole to prevent the slurry in the test pipe from entering the piezometer.
