TURBOPUMP SET Russian patent published in 2001 - IPC

Abstract RU 2169862 C2

FIELD: mechanical engineering; turbopump sets. SUBSTANCE: invention can be used in sets handling liquid oxygen. Proposed set has turbine, two-stage pump with separated shafts of stages. Each stage has pre-engaged screw and centrifugal impeller. Low-pressure stage rotation drive is made in form of hydraulic turbine located between pre- engaged screw and higher pressure stage impeller. Screw has covering ring shell by means of which screw is secured in cylindrical projection of impeller cover disk by means of splines. EFFECT: reduced overall dimensions and weight of set, enhanced reliability and simplified design. 1 dwg
