SU1525334A1 - Sealing system for suction dredge impeller - Google Patents

Abstract

The invention improves durability and reliability by reducing the wear of the sealing ring 4 of the throat 2 of the impeller 3. The cylindrical part 6 of the sealing ring 4 is designed as an alternate coaxial bushing 11, 12 of elastic wear-resistant material and solid material, which allows the load to be redistributed between different parts of the neck 2. In the sleeve 12 of the solid material placed in the middle of the sealing ring 4, pockets 13 are made. Abrasive particles accumulate in pockets 13 and black. Without channels 14, it is diverted to pump suction zone 15. 1 hp ff, 4 ill.
