EFFICIENCY OF USING OF THROTTLING ELEMENTS AT THE PUMP PLANTS
DescriptionIn the article, we have examined the operation modes of the pump units when their efficiency is regulated by the force of throttling. Formulas for optimal operation mode are derived and zones for efficient work of the electric pumps with different initial parameters of reg-ulations are defined

TURBULENT TRANSFER EFFECTS OF THE FINE PARTICLES IN THE LIQUID PHASE OF DYNAMIC SEPARATORS
DescriptionThe turbulent movement of the liquid with dispersed phase in the channels of thin layer clarifiers and hydrocyclones is reviewed. The evaluation of the dimensions of the particles, which are taken by the turbulent pulsation is performed. The turbulent sedimentation of the fine phase is researched as a type of a process of diffusion. Using the equations from the theory of mass transfer and the edge of the turbulent level, the coefficients of the speed of the transfer of the particles are acquired. The results of the calculations, covering the effectiveness of the turbulent separation are provided, with the use of the models of perfect mixing and displacement
