The
DSA 500 analyzer is
being used for the acquisition and analysis of a turbo engine’s main
parameters.
Specific to
the testing of turbo engines is the presence of two independent-speed
rotors in their construction, GG and PT.
Monitored signals:
-
Tachogenerator
signals (their frequency is proportional to that of the rotor’s speed)
-
Engine casing vibrations
-
Input gas temperature in
power turbine
-
Signal of
the turbine-type flow transducer
From the
joint vibrations signal, the Order Analysis A function extracts
the harmonics family specific to the GG rotor.
From the
joint vibrations signal, the Order Analysis B function extracts the
harmonics family specific to the PT rotor.
The fundamental
components of the two families are being tracked simultaneously with the
other measured parameters, and graphically displayed by time.
The
recordings are available for the generation of the Bode diagrams and
comparison to the limit or reference diagrams.
The
analysis windows can be individually or simultaneously monitored,
function of the test specificity and necessary information.
Data can be
saved in an instant-access proprietary format or an Excel-compatible
format for various calculations or presentations.
