Industrial Applications Of Hydrohoist Systems In The Power Industry And Alumina Plants

The paper deals with hydraulic transport of thin and dense slurries. Based on mathematical modelling of three-phase flow, dynamic properties of the systems for pumping of thin slurry are solved. Theoretical calculations were experimentally verified both at the testing hall and in real operation. For thin slurry (e.g. bauxite slurry), a three-chamber hydrohoist with float is used. Dense slurry (e.g. ash and water) is transported from the power plant to a deposit site by means of a three-chamber hydrohoist with sealed separator (piston).
