PUMPING UNIT FOR HANDLING LIQUID AND STRUCTURIZED MEDIA

摘要

FIELD: mechanical engineering; pumps. SUBSTANCE: invention relates to multipurpose pumps and its can be used for pumping liquid and structurized media with large content of dispersed components. Proposed pumping unit contains drive connected with power source, shaft installed in bearing housing, screw, housing of pumping unit, and intake and discharge branch pipes. Housing of pumping unit is essentially truncated cone for screw changing into cylinder with scroll part for wheel with blades. Screw with variable angle of helix and widening screw channels changes into blade wheel. EFFECT: increased head of pumping unit. 1 dwg
