SUPERCHARGER FOR TESTING IMPELLER ELEMENTS OF A SHAFTLESS PUMP Russian patent published in 2021 - IPC F04B51/00 G01M13/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, namely to test devices, and is intended for simulation of operation of flow section of impotent pump unit with various geometrical parameters. Blower for testing impeller pump impeller elements includes pressure and suction branch pipes with flanges, body with stiffness ribs, sleeve, first and second bearing assemblies. Sleeve is installed in housing with possibility of rotation by means of first and second bearing units, is made with through holes for attachment inside elements of impeller of impeller pump and comprises on outer surface pulley to ensure rotation of sleeve through belt transmission from electric motor. Each bearing assembly comprises radial-thrust bearing, clamping ring and cover of bearing assembly. Cover of the first bearing assembly is permanently fixed on the delivery branch pipe with a flange and is detachably fixed on the housing, cover of the second bearing unit is permanently fixed on the suction branch pipe with a flange and is detachably fixed on the housing. A flow straightener is installed in the suction branch pipe with a flange.

EFFECT: invention is aimed at expansion of functional capabilities of tooling for tests by provision of possibility to perform tests of impeller pump impeller elements, increased efficiency and efficiency of tests at simultaneous simplification of design of equipment for tested elements, and consequently, its manufacture and repair.
