GAS-TRANSFER SET POWER UNIT Russian patent published in 2006 - IPC F02C7/12 F02C9/00 

FIELD: mechanical engineering; gas transfer sets.

SUBSTANCE: proposed power unit of gas-transfer set has compartment, centrifugal air fan, drive gas-turbine plant, air conduit to discharge hot air into atmosphere, pressure differential sensor, air flow rate meter, first contamination sensor furnished with internal failure self-diagnosing system, second contamination sensor, first OR logic gate, first pressure differential setter, first comparator, second air flow rate setter, second comparator, second OR logic gate, comparator with memory and AND logic gate. Centrifugal air fan is connected with compartment, first and second adjustable setting are connected to first inputs of first and second comparators, respectively, whose second inputs are connected with pressure differential sensor and metering device, respectively, and outputs, with first and second inputs of second logic OR gate whose output is coupled with comparator whose output is connected to first input of AND logic gate. First contamination sensor, internal failure self-diagnosing of system of first contamination sensor and second contamination sensor are connected by outputs with first, second and third inputs of first OR logic whose inverted output is connected to second input of AND logic gate.

EFFECT: improved reliability of gas transfer set in operation.
