PULSING ATTACHMENT

摘要

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
