VORTEX PUMP Russian patent published in 2017 - IPC F04F5/42 

FIELD: engines and pumps.

SUBSTANCE: vortex pump is designed to perform ejection process in a liquid-liquid medium. The pump includes a cylindrical body, a tangential branch pipe for working fluid flow inlet, a tangential branch pipe for mixed flow outlet, a branch pipe for ejected liquid flow inlet located coaxially relative to the cylindrical body, the diameter of the branch pipe of working flow inlet is at least 0.15 of the cylindrical body diameter, the sum of cross-section areas of tangential branch pipe for working flow inlet and the branch pipe for ejected flow inlet is 0.5÷0.9 of cross-section area of tangential branch pipe for mixed flow outlet, the distance between the lower edge of tangential branch pipe of working liquid flow inlet and the upper edge of tangential branch pipe for mixed flow outlet is at least 1.0 of the cylindrical body diameter, the value of the cross-section diameter of the branch pipe for ejected flow inlet is more than 0.5 of the diameter of the device cylindrical body.

EFFECT: production of maximum possible ejection coefficient value.
