reduction ratio .................................... ≧ 90%
Reduction ratio
greater than 10-fold, the largest car factory gear box (FAW)
products, to ensure its mechanical transmission, low noise.
Can balance the nation's largest cement
separator rotor, the figure is a cement mill separator,
diameter greater than 5 m. The
machine working speed: 85 rev / min for process balance. Beijing
Power Equipment Plant produces maximum rotor diameter is 6500mm.
A. driving part adopts 75 kilowatts
inverter motor supporting machinery with stage transmission scheme
can achieve optimal power output. Inverter
using ABB or Siemens products, use the Beijing Motor Plant inverter
motor or equivalent level of quality products;
B. sensor uses the
company's own production of solid sensor, the sensor by users prove
their failure rate is almost zero;
C.
Measurement vector solvers
computer, digital display form. This machine has the following
characteristics:
HP-16
hard bearing balancing machine computer electrical measurement
instrument is a balanced machine dedicated computer: high
reliable industrial computer chip circuit, direct 220VAC power
supply, strong anti-interference, adaptation to unstable power
supply conditions, for the unstable speed can also be measured.
Software vector solution measurement data, large font digital
display. Overall 4 digit display input parameters, a key
indicator of static balance, can be set parameters of the data
stability.
The measured
data can be processed and processed after shutdown: the
different parameters can be transformed, and the measured
results are more consistent with the actual measurement results.
The operator if you need other parameters of the solution
results, you can enter the corresponding parameters, the
corresponding calculation results. Once again change the
calculation parameters, the same can be directly obtained after
the change of the calculation results. No need to boot the
measurement again.
Automatic (or
manual) memory while driving the engine shutdown function,
customer self calibration function, recovery of the factory
calibration function, sensor signal line fault judgment and
indication function.
D.
The test results
report and report single electronic document records, can be
output to the SD card or TF card.
E. fuselage sub-structure. Between
the two sections of the fuselage length 3.5 m trench opened to
accommodate large-diameter rotor (see outline drawing host).
F. Compensation and correction method for process mandrel and
electric measuring box with bending damage:
When the balance process shaft is used for a long time, it will
bend. When the bending degree is greater than 0.05 mm, the
balance result can not meet the technological requirements.
If the value is too large to correct the unbalance, press the
"initial unbalance key", press the "storage key" after the data
is stable, turn the rotor over 180 degrees relative to the
process axis after shutdown, slowly start the balancer, press
the "180 degrees unbalance key" and press the "storage key"
after the data is stable. Then press "secondary compensation 2"
to compensate for 2 transposition. Such measurement results will
eliminate the errors caused by the bending of the balance axis.
