DETERMINATION OF OPERATIONAL HYDROPULPER PARAMETERS ON THE BASIS OF ENERGY BALANCE

Abstract

The paper proposes a methodology for calculation of hydropulper parameters on the basis of energy balance. A hydropulper rotor is considered as a pressurizing pump with p_т which is spent in a bath of the hydropulper for overcoming the hydraulic pressure losses in fiiction Δр_тр diffusion Δр_д and vorticity Δр_у, due to shocks. The pressure z₀ p g is taken into consideration and it is determined by a bath filling. An energy balance equation is formulated Qp_т = ρK_Nn³d⁵ which is solved by anumerical method for determination of an expenditure Q in a circulation circle and pressure p_т created by a rotor. The power consumed by the hydropulper rotor is determined by a formula Np = Qp_т
