Fluid seals development for coal liquefaction slurry pumps. Final report, 28 September 1982-31 January 1986. [Centrifugal and reciprocating pumps]
The results of a fluid seal developemnt program for coal liquefaction centrifugal and reciprocating slurry pumps are presented. The preliminary evaluation indicated that the best fluid seal concepts were the hydrostatic convergent tapered bore floating ring and the hydrostatic orifice compensated floating bushing. Detail evaluation and analysis were performed and the tapered bore floating ring seal was selected for final design and fabrication. The seal rings were constructed from solid tungsten carbide K68 with a convergent taper ratio of 2.0 and nominal diametral exit clearances of 0.002 to 0.003 inch. The laboratory testing demonstrated satisfactory leakage and negligible wear with synthetic slurry at typical field conditions. The centrifugal seals accumulated 72 hours with final leakage rates of 0.05 to 0.15 gpm. The reciprocating seals accumulated 63.3 hours with leadage rates of 0.04 to 0.05 gpm. The reciprocating seal field testing demonstrated successful field operation with actual process fluids. A total of 506 hours was daccumulated with no significant wear and leakage rates of 0.02 to 0.05 gpm. 32 refs., 143 figs., 32 tabs.
