Slurry pump seal Author: strong industry Pump Published: 2017-09-06 Clicks:
Because the inner diameter of the seal ring of the slurry pump is smaller than the outer diameter of the pump shaft or shaft sleeve, the seal ring can be tightly held on the shaft, plus the pressure of the liquid, the sealing effect is achieved. Its interference is generally 0.5 ~ 1 mm, it is related to the journal, speed and pressure. When the interference is too large, it will burn out and harden the filler. To prevent the packing from rotating with the shaft, it must be fixed with a compression sleeve. The degree of tightness of the gland can be as long as the packing is not rotated with the shaft, and the packing is not rotated with the shaft, and the gap between the stuffing box inner sleeve and the gland can be filled up. When the pump shaft is made of steel, bronze should be used as a protective sleeve to prevent the steel shaft from being bonded to rubber. If bronze cannot be used, a chrome-plated bushing can be used.
