Peristaltic Pumping: A New Approach to Pumping Solids in Slurry Form. Report of Investigations.

摘要

A study was made into the capabilities of the peristaltic pump for pumping solids in slurry form. An experimental peristaltic pump,consisting of a series of six 3-in.-diam pinch valves,was constructed and tested under various operating conditions. Slurries,consisting of limestone chips and water,were successfully pumped through a 3-in. line with a 30-ft vertical lift. Pumping parameters were determined in an effort to maximize output. Experimental data was collected by means of grab samples and volumetric measurements. The results were plotted graphically as a function of pumping cycles. An analysis was also made in reference to applications of peristaltic pumping in vertical blind shaft boring and mud/water removal in underground coal mines. Suggestions are made in regard to areas of improvements to the system. (ERA citation 04:014242)
