OIL SYSTEM OF POWER GAS TURBINE UNIT Russian patent published in 2014 - IPC F02C7/06 

FIELD: motors and pumps.

SUBSTANCE: oil system of power gas turbine unit (PGTU) relates to motor building, namely to PGTU oil systems, used in gas pumping and electric stations for driving of various units (pumps, gas and air compressors, electric generators etc.). The proposed PGTU is featured by the use of independent drainage vessels for each oily cavity of free turbine, connected to the individual scavenge pump, that allows to exclude in the oil scavenge system disbalance in operation of the pumps induced by moves of air flows from one oil cavity to another one through the integrated drainage cavity.

EFFECT: invention will allow to avoid the use of complementary extraction pump with electric drive, and mutual integration of pump mains of delivery pumps in the oil supply system will allow to improve the reliability of PGTU operation in case of failure of one of delivery pumps.
