HP-15 hard support balancing machine system will be
used automatically after startup. Start the
balancing machine to carry out dynamic balancing
measurement. After memorizing the data, stop the
machine, and then input the supporting parameters
for automatic calculation.
This is the simplest balancing machine measuring
instrument, which can learn to operate in a short
time and will not forget its operation method after
a long time.
The purpose of our product design is to facilitate
the use of the model, not because the use of
computer technology to make the product show a
strong computer flavor, it is a machine for working
people to use. Without memorizing so many passwords,
you can learn to operate in 10 minutes, and people
in the same workshop can use them.
Our product design has been finalized through the
repeated modification of the production line
practice, and we are still continuing to optimize

HP-15 hard support balancing machine computer
intelligent electrical measurement system is a special
computer for balancing machine:
This is a permanent standard mechanical and electrical
measuring system of hard support balance
The rotor with different shape and weight does not need
to be recalibrated. The magnitude and angle of the
unbalance can be measured at one start.
There are five groups of dynamic balance data display,
which can directly see the factory status and static
It only needs to start once. Parameters can be input in
time after measurement
Display: TFT color monitor
Interface: one TF, one SD, output electronic report
Measuring circuit and basic system:
After one factory calibration, it meets the following
All signals of the balancing machine can be
calculated: the amplitude frequency characteristics of
the electric measuring box meet the following
Display value changes less than required
The amplitude frequency characteristic of the soft
support speed sensor signal is the first power of the
angular frequency ω, v = K1 * ω
The amplitude frequency characteristic of the signal of
the hard supported piezoelectricity sensor is the
quadratic of the angular frequency ω,
v = K2 * ω 2
The amplitude frequency characteristic of the
signal of the hard support speed sensor is the third
power of the angular frequency ω,
v = K3 * ω 3
The phase frequency characteristics of the electric
measuring box meet the following requirements: within
the working speed range of the machine, the measured
unbalanced amplitude of the electric measuring box
changes little, and the displayed angle changes less
than the requirements
It ensures that the balancer displays the same
amount of unbalance (magnitude and angle) at different
speeds without calibration.

This is the simplest balance machine measuring
instrument with high reliability, industrial computer
chip circuit, strong anti-interference, suitable for
unstable power supply conditions, and it can also be
used to measure unstable speed. The circuit structure
with the least hardware processing analog signals. Two
analog signals adopt synchronous sampling mode. The
hardware of pulse circuit has only one level input
buffer circuit. The software solves the measurement data
of vector, and displays the figure and figure of vector.
Comprehensive 4-digit digital display input parameters,
static balance quantity display, sensor quantity
display, data stability function of settable parameters.
The application of the latest computer technology,
high-speed dynamic sampling, comprehensive vector
solution, a new hardware structure.
It can process the memorized measurement data after the
main engine stops: it can transform different parameters
to get more practical measurement results. If the
operator needs the solution results of other parameters,
he can input the corresponding parameters and get the
corresponding solution results immediately. By changing
the calculation parameters again, the calculation
results after the change can also be obtained directly.
No need to turn on the machine again for measurement.
Automatic (or manual) memory drives the main engine
shutdown function, customer self calibration function,
and restores the factory calibration function.
The electronic documents of test result report and
report record can be output to SD card or TF card.
The measurement data is calculated by
computer software vector, and the whole interface is in
the form of digital and graphic display. The machine has
the following features:
Start the machine to directly measure the dynamic
balance data, input or modify the parameters such as the
support mode of abcr2r1 after stopping the machine (the
input parameters have the same effect before and after
starting the machine), and the electric measuring box
will automatically recalculate the separation results.
Automatically judge that the measured data is stable and
effective. If the data is stable, the electric measuring
box will automatically memorize it.
3. In case of power failure, retain the last memorized
data: restart the machine --- the electric measuring box
displays the last memorized measurement data.
4. The computer measurement system can directly read the
size (kg or G) and phase (degree) of the heavy (light)
weight in the form of digital and graphic display.
Store the input parameters of 99 rotors.
6. After the data is memorized, the main engine can be
automatically driven to stop.
7. Balance accuracy calculator, input the rotor
operation parameters (using speed and mass) to calculate
the residual unbalance value under the standard balance
8. Self test function of measurement system.
9. The magnification of the automatic control system is
convenient for some process requirements requiring fast
operation Automatic matching of left and right sensors
solves the problem of left and right swing frame
asymmetry, which makes the linear working range of
balancing machine larger.

Super wide working speed
Add compensation function in 2019
Simple compensation: "v-v0" is used to compensate the
inherent unbalance value of the fixture
Secondary compensation: 2 transposition compensation (V0
+ V180) used for correction compensation of different
center values of fixture
3 rotation compensation (V0 + V120 + V240)? For fixture 3 fixed
positioning correction compensation
5 rotation compensation (V0 + V72 + v144 + v216 + v288) is used for
fixture 5 fixed positioning correction compensation
Key compensation: ((v0-v1) k% (?) used for mass
production drive key quality correction
Correction operation method of bent process mandrel:
When the balance process shaft is used for a long time,
it will bend. When the curvature is greater than 0.05mm,
the balance result can not meet the process
Install the rotor and start the machine to measure the
unbalance. If the value is too large and the correction
is smaller, press the "initial unbalance key". After the
data is stable, press the "storage key". After the
machine stops, turn the rotor 180 degrees relative to
the process axis, 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 carry out 2 transposition
compensation. Such measurement results will eliminate
the error caused by the bending of the balance shaft.
