| 摘要 |
The invention relates to a method and apparatus for maintaining suitable velocity or velocity range in a slurry pipeline system of the type with a water pipeline return and slurried material pipeline output with more than one slurry injection point. A single set of primary pipelines, one water (32) and one slurry (34), is able to serve multiple points of hydraulic injection by means of slurry pipeline flowmeters (84, 86, 88) downstream from each slurry injection water by-pass junction (76, 74, 72), with each flowmeter actuating water control valves (78, 80, 82) to bypass water to the slurry pipeline 34 at the respective junction so as to maintain slurry pipeline velocity within prescribed limits. |
