CENTRIFUGAL PUMP TO TRANSFER AND MILLING OF CONSTRUCTION MATERIALS

摘要

construction industry, preparation and transfer of finely dispersed grouting of construction materials. SUBSTANCE: centrifugal pump has body housing impeller with blades. Grooves used for compression and rarefaction of peripheral zone of flow of transferred material are made in body opposite to face surfaces of blades. Profile of grooves in internal surface of body is homothetic to profile of face surface of blades of impeller. Number of grooves corresponds to number of blades of impeller. EFFECT: increased technological capabilities of pump when transferring construction materials thanks to purposeful selection of dimensions of dispersed particles of milling. 3 dwg
