METHOD OF CHECKING TURBOPUMP SET BEARING FOR WEAR Russian patent published in 2001 - IPC

Abstract RU 2175411 C2

FIELD: turbines and pumps. SUBSTANCE: method of diagnosing wear of bearing of turbopump set operating on pumped component is based on checking parameters of bearing hydraulic duct. In operation, ratio of pressure in bearing space to pressure in high-pressure space is checked with measurements of values of drop of pressure rations from initial switching on of set to moment of checking. EFFECT: improved accuracy of checking, facilitated automation of diagnosing process. 1 dwg
