Measurement of Axial Impact Force of Pipeline Transporting Thick Pastes

Abstract:

Due to alternating work mode of twin-cylinder of solid pump during high pressure pipeline transporting thick pastes, largde axial impact force is exerted on the pipeline, which makes pipe clamps, supports and bolts of flange damage to failure. By using twin dynamic force transducers and designing coresponding installation components for the transducers, impact forces at different flow rates, positions of the pipeline and transportation pressures were measured. Conclusions can be drawn as following: impact force increases with increasing flow rate, and decreases with increasing distance from the outlet of pump. The increased amount of impact force with increasing flow rate is larger under larger transportation pressure than that under samller transportation pressure. It is better to transport thick pastes at low system pressure, and to install more pipe clamps in the front part, and reverse in the back part of pipeline.
