For peak performance, today's turbines
require multiple balancing procedures in the manufacturing
process as well as during overhaul. To assure the lowest
vibration levels and the highest efficiency sound, reliable
techniques must be applied to the individual blades, the
disk and the final turbine assembly.
Our computerized moment weighing scales and
BLADISNet Software
can optimize blade distribution by determining the relative
or absolute moment of each blade and selecting the best
location within the set. Our WM scales greatly reduce the
initial unbalance in the assembly and streamline the
balancing procedure.
Schenck's total support program goes beyond balancing to
provide equipment and technical services for balancing
program certification, rotor assembly
tooling and handling fixtures (1.2MB Adobe.pdf file),
detailed process documentation and engine specific training
programs. Schencks total support program ensures a timely
and efficient launch for every engine overhaul
program.
Jet Engines
Schenck offers a complete line of vertical and horizontal
balancing machines specifically for low-speed balancing of
jet engine modules and assemblies. All systems are designed
to ARP 4050 and 4048 standards, and can be equipped with
complete enclosures to eliminate windage and ensure the
safety of personnel.
Low-pressure modules (turbine & compressor),
high-pressure modules (turbine, compressor and fan), and
intermediate modules if appropriate, can be balanced on a
vertical machine prior to assembly. Both static and dynamic
models are available for nearly any rotor weight.
A complete range of horizontal machines is also available
for balancing subassemblies. Units can be equipped with
end-drive, belt-drive, or end-and belt-drive depending on
the rotor's horsepower requirements and the recommendation
of the manufacturer.
Complete quality control packages are also available for
balancing machine performance testing, tooling audit and
control, and rotor quality monitoring. All packages are
designed in compliance with SAE/ARP recommended practices
with all proving rotors traceable to the National Institute
of Standards and Technology (NIST).
Power Generation
Schenck Trebel's broad range of expertise is also a valuable
resource for the manufacture and overhaul of generators and
steam and gas turbines for the power generation industry.
While many balance these large turbines in multiple steps at
low-speed, others balance them as complete assemblies at
operational speed, or even at overspeed, in elaborate
high-speed installations.
We work closely during the development phase of new
generation turbines, and can custom tailor our universal
machines for any application. Several drive configurations
are available including multi-speed transmissions with up to
8 speeds for varying torque requirements. Special roller
carriages, tooling and a full range of instrumentation
features can provide precision results!
