DELIVERY PRESSURE DETECTING SYSTEM FOR LONG DISTANCE SLURRY PIPELINE
摘要
<p>A delivery pressure detecting system for long distance slurry pipeline comprises a detection ring pipe (2) connected with a main pipe (1) in parallel, a micro differential pressure transmitter (4) and a hydrargyrum U-tube differential manometer (3), the micro differential pressure transmitter (4) and the hydrargyrum U-tube differential manometer (3) which are arranged at two ends of the detection ring pipe (2). A main pipe valve (7) is arranged in the main pipe (1). A ring pipe inlet valve (5) is arranged at the inlet end of the detection ring pipe (2), and a ring pipe outlet valve (6) is arranged at the outlet end of the detection ring pipe (2).</p>
