ICE SEAL FOR ROTATING SHAFTS

A sealing device utilizing water ice to form a very close-fitting liquid water capillary seal about a rotating shaft has been designed, built, and tested. The experimental shaft diameter was 6 in. (15.24 cm) and it rotated at 600 rpm. The observed leakage rates were below 0.05 cu in/sec (0.8 cu cm/s) for differential pressures up to 600 psi (4150 kPa). The maximum power required to drive the shaft was less than 500 W. A set of basic equations was developed to predict the seal performance. Experimental results indicate the basic equations are sufficiently accurate for future seal designs. (Author)
