抄録

When centrifugal pumps are used for pumping high viscosity liquids, a problem exists where the pump performance decreases as the viscosity of pumped liquid gets higher. The cause of this, i.e., the change of influence on the efficiency of various losses (for example, disc friction loss, the loss owing to the channel from the inside impellers leak loss, and collision loss), accompanying the change of flow within the pumps, will be considered. In this study, the effect of the clearance ratio on the pump performance, when high viscosity liquid is pumped up, was investigated. It was clarified that the pumping performance was affected by the clearance ratio and Reynolds number.
