Abstract
In the article theoretical researches of hydrodynamic processes of disk unloaders of mine pumps, axial oscillatory processes of the pump rotor and influence of various param-eters of the unloading device on dynamic stability of the rotor-knot unloading system are presented. For the cases of turbulent and laminar water flows in the flowing part of the discharge device, hydrodynamic processes were investigated. The theoretical characteristics of the oscillatory process of the pump rotor and the period of variation of the oscillation amplitude are obtained.
