A Study on New Centrifugal Pump for Slurries 891942
A new type of centrifugal pump which can be used for transportation of alternate fuels such as coal slurries was tested. Design and performance of the pump, and analysis of the fluid flow in the pump is presented. The unique internal flow pattern, which was determined using a high speed camera, results mainly from the recessed impeller design and the geometry of the blades. The qualitative and quantitative analysis of the flow profiles indicate the existence of suitable conditions for a decrease in the direct contact of the abrasive particles of the slurry with the interior surface of the pump which translates to longer maintenance-free performance.
The test pump performance for slurries at higher concentrations compared well with the existing slurry pumps. The highest concentration used during the test was 60% by weight. At this level the maximum efficiency of the pump was 30%. The corresponding power required and the flow rate were 5.97 kW and 528 L/min, respectively.
Some recommendations for further development are made.
