Control system of apparatus for transporting slurry

摘要

A control system for an apparatus for hydraulically transporting sedimentation prone slurry containing pulverized or powdered solid material mixed with water. A pipeline resistance of a slurry transport pipe at a proper location is detected by varying the flow rate of the slurry at the starting point of slurry transportation, and the critical flow velocity for slurry sedimentation is determined by using the pipeline resistance. The slurry is economically transported at the flow velocity above the critical flow velocity.
