Abstract

A system and method for determining a critical suspension speed of an impeller in a solid-liquid stirred tank belongs to the technical field of critical speed determination. A relationship is established between a voltage of a measurement electrode and a solid-liquid suspension state to avoid the problems of strong subjectivity and large deviation appearing in existing critical suspension speed determination based on empirical formulas and human eye observation. An electrode voltage ratio is taken as a determination criterion, which is only related to a spatial density of solid particles in a liquid phase.
