Abstract
580,658. Stuffing-box substitutes. ROTHELI, R. July 4, 1944, No. 12759. Convention date, Feb. 5, 1943. [Class 122 (v)] In a stuffing-box for rotary pumps for working acids and lyes comprising mutually sliding sealing surfaces arranged in a plane perpendicular to the shaft axis, an elastic sleeve 3 is firmly fixed to a carrier sleeve 2 by means of axial pressure influencing axially movable sealing members 4a, 4b, 5 and 6 so that the sealing surfaces so formed are pressed together. The members 4a, 4b are of porcelain and rotate with the carrier ring 2 and elastic sleeve 3 the whole being carried by the shaft 1, whereas sealing members 5, 6 also of porcelain are held stationary. Axial pressure is transmitted from gland screws 13 through the member 6 to compress the elastic sleeve 3 and hence press together the sealing surfaces. Annular rings 9 of softer porcelain may be inserted between the rotating and stationary sealing members. Leakage fluid acts as lubricant and collects in an annular space 11 to pass through a passage 12 for recirculation.
