DEVICE FOR DETERMINING THERMAL-OXIDATIVE STABILITY OF FUELS UNDER DYNAMIC CONDITIONS Russian patent published in 2017 - IPC G01N33/22 

FIELD: measurement technology.

SUBSTANCE: invention relates to laboratory methods of assess of the performance characteristics of motor fuels, in particular to determine thermal oxidative stability (TOS) of fuels under dynamic conditions, and can be used in the petrochemical, aerospace, automotive and other industries. Installation comprises a vessel 26 with the test fuel, connected conduit in series with the pump 27, the pre-filter 28 and the pipe 2 in the bottom of a vertically mounted tubular body 1, on top of which there are two outlet nozzle 3, 4, in one of which the test filter 5 is and fuel temperature meter 7. The upper tubes interconnected through a check valve 34. Concentrically in the housing valuation tube 8 is mounted. In the installation a special unit is introduced consisting of protective cylindrical metal casing 19, inside which a removable cover is installed, turning into a hard cylindrical holder, in the channels where the steel shell 17 and the transition sleeve of temperature sensors 23 are placed, the sensors 18 are distributed throughout the length of the tubular portion of the removable cover. There is a program control unit 33, connected to the sensors and actuators.

EFFECT: invention provides increased test reliability and accuracy assessment of TOC fuels.
