IMPELLER SHAFT [14 records]

Record 1 2021-07-14

English

Subject field(s)
  • Fire-Fighting and Rescue Equipment
CONT

When operating in the pressure mode, the transfer valve redirects the discharge from one impeller to the intake of the second impeller... The second impeller can only discharge the quantity given to it by the first. However, the pressure generated by the first impeller can be used by the second. Again, because the impellers are rotating on the same drive shaft, they will each produce a specific quantity and pressure. The second impeller takes the pressure given to it by the first impeller and adds its pressure.

Record 6 1998-11-16

English

Subject field(s)
  • Papermaking Machines
  • Pulp Preparation (papermaking)
CONT

Mixer. Equipment which disperses chemicals uniformly with the pulp. Mixing of pulp fibres with bleaching fluids is one of the most important operations in bleaching or brightening of pulp. Two types of mixers are presently used : dynamic and motionless(static) mixers. In the dynamic mixer, mixing results from the physical motion applied to the fluid mass by an agitator or mixer which is generally a rotating impeller located on a shaft. Power is supplied by an external motor.

French

Domaine(s)
  • Machines à papier
  • Préparation de la pâte à papier
CONT

Mélangeur. Équipement dispersant uniformément les produits chimiques dans la pâte. Le mélange des fluides de blanchiment avec les fibres de bois est l'une des opérations les plus importantes du processus de blanchiment ou d'éclaircissement de la pâte. Deux types de mélangeurs sont couramment utilisés : dynamique et immobile (fixe). En ce qui concerne le mélangeur dynamique, le mélange est le résultat du mouvement physique appliqué à la masse fluide par un agitateur généralement constitué d'un rotor fixé à un arbre. L'énergie est fournie par un moteur externe.

Subject field(s)
  • Papermaking Machines
  • Pulp Preparation (papermaking)
DEF

Mixers which fluidize pulp at medium consistency (10-15%) by applying high shear forces to it in a narrow gap between a fast rotating part and a stationary part. Bleaching chemicals can be dispersed thoroughly into the fluidized pulp.

CONT

In the dynamic mixer, mixing results from the physical motion applied to the fluid mass by an agitator or mixer which is generally a rotating impeller located on a shaft. Power is supplied by an external motor. High-shear or medium-consistency(MC) mixers are a special type of mechanical mixers.
