Abstract

FIELD: pulsing attachments. SUBSTANCE: pulsing attachment has jet pump whose lower part made in form of cylinder contains installed hollow spring-loaded piston with valve. Depression effect produced at the inlet of jet pump results in self-sustained vibrations of piston which give rise to self-sustained waves alternating in different points of the volume in the zone under the device which promote intensification of pumping-out of fluid. EFFECT: higher efficiency of pumping-out of fluid due to separation of flow into small portion and production of high short-time instantaneous depressions. 1 dwg

Purpose: improving work efficiency. The inventive device comprises a jet pump, in the lower part of which, made in the form of a cylinder, a hollow spring-loaded piston with a valve is installed. The creation of depressive effects at the inlet to the jet pump leads to the occurrence of self-oscillations of the piston, which create depressive undamped waves at different points in the volume under the device that contribute to the intensification of the liquid pumping process. Positive effect: increased efficiency in the work on pumping out liquid by dividing the flow into small portions, creating increased short-term instantaneous depressions.
