A Kind of Pressure Detection Method in Long Distance Ore Slurry Pipeline

摘要：

The problem of pressure detection in long distance ore pipeline transport is one of the most important technical indexes to ensure pipeline safety, efficient transportation. This paper presents kind of pressure detection method in long distance ore slurry pipeline, with detection loop pipe, microdifferential pressure transmitter and mercury u-tube difference-pressure meter to form the pressure detection. Detection loop pipe is identical with main pipe, parallel set with main pipe. Calculation of the unit on-way resistance in the current velocity and concentration combined detection of the actual length of the loop pipe. Da Hong Shan pipeline in practical application indicates that the method used to pressure detection, not only solved problem of longdistance pipeline pressure detection, but also solve the problem error is fairly great between Theoretical value and actual value for two-phase flow in turbulent state, to protect the long distance ore slurry pipeline security, stability and efficient operation.
