Axial releaf of the leak-tight pump rotor

Leakage from the periphery to the centre in the pump pockets reduces the pressure in them, leakage from the centre to the pheriphery increases it. Taking this into account, the rotor positive hydraulic axial balancing system of the leak-tight pump, possessing increased reliability, in comparison with the hydraulic pivot is proposed. The computation method of weighting device supporting power is developed on the basis of the analysis of the flow picture in the pocket. The test results of the given discharging gear are presented
