METHOD OF DETERMINING LEAKAGE OF ASSEMBLIES HAVING MOVABLE COMPONENTS Russian patent published in 2013 - IPC G01M3/00 

FIELD: physics.

SUBSTANCE: leakage is determined using readings of a differential pressure sensor, wherein according to the invention, the beginning of operation of the differential pressure sensor and the beginning of operation of the program of the vibration stand based on vibration action on the assembly is synchronised in time; differential pressure readings are selected in conditions of varying overload from the beginning and to the end of raising pressure and leakage of the assembly is determined from the value of gas flow rate, using, when determining gas flow rate, its average value in the range of vibration overloads over the selected time interval.

EFFECT: high accuracy of determining leakage of assemblies.
