YFW-10000 type fan impeller
balancing machine
（1）, overview
With the development of modern industry, high precision and high
speed rotating machinery, to eliminate the vibration of the
machine has become increasingly important for rotating machinery
(such as motor, blower, diesel engine, automobile, aircraft),
the vibration of rotating components will directly affect the
efficiency of the machine, the machine life and personal safety.
Don't move the balance is one of the main reason of rotating
machinery vibration, so in order to effectively solve the
problem of the vibration of the machine, the rotary body
(hereinafter referred to as the rotor dynamic balance test) is
one of the essential technical measures.
Hard bearing balancing machine is a universal balancing machine
model has been developed rapidly in recent years, the use of a
relatively wide range, it has the characteristics of high
efficiency, simple operation, intuitive display, rapid
measurement, good stability, is a kind of dynamic balancing
equipment is more advanced, dynamic balancing is suitable for
all kinds of rotating parts, this series of balancing machines
become more and more popular with users of the products.
YFW-10000 type fan impeller balancing machine is a kind of
balancing machine designed specially for fan manufacturing
industry. This machine is designed for horizontal hard bearing,
universal joint drive, digital display, etc.. The machine has
the following characteristics:
A: measurement system can use digital display, can be directly
read out the weight (light) the amount of the size (kg or g),
phase (degree). Also has the unbalanced quantity memory and the
measurement system self checking function.
B: the measurement system uses a novel circuit and a reasonable
structure of the layout. Linear and digital integrated circuits
are all standard series dual in-line package of international
general domestic production, data transmission relay adopts
program-controlled switches relays, high reliability, convenient
maintenance.
C: the core circuit of the electric measuring box is the
tracking band-pass correlation filter, which has good filtering
and frequency tracking performance. Due to the adoption of the
automatic bandwidth switching circuit, the contradiction between
the fast response and the stability of the electric measuring
box is reasonably solved.
D: This machine mechanical and electrical energy conversion
device using piezoelectric sensor, because there is no
mechanical motion, so the failure rate is very low, and low
speed performance is good (the minimum speed of the machine can
be up to 60 rpm).
E: in addition to the general characteristics of the horizontal
hard bearing balancing machine, but also specifically for the
balance of the fan impeller characteristics given 2 important
parameters. First, the maximum balance of the rotor diameter of
3500 mm (35 fan impeller); second, the maximum rotor weight of
10000 kg, can be guaranteed to detect the maximum sensitivity of
the vast majority of the size of the machine's impeller.
F: low speed performance is good. Minimum operating speed 60 rev
/ min. Energy saving and safety.
The computer vector is used to calculate the measured data, and
the digital display form. This machine has
Following characteristics:
1: the computer measurement system with digital display, can be
read directly
(light) the amount of the amount of (kg or g), phase (degree).
Auto avoid zero ---r1, r1, b, three parameters can not be set to
zero function. Self checking work with unbalanced quantity
memory and measurement system
Can.
2: measuring system using the computer electrical testing
circuit, high reliability, easy maintenance.
3: the core circuit of the electric measuring box is the
tracking band-pass correlation filter, which has good filtering
and frequency tracking.
Can.
Due to the adoption of the automatic bandwidth switching
circuit, the fast response and the stability of the electric
measuring box are solved reasonably.
Contradiction between,
The electric measuring box has excellent low speed performance.
4: users can choose the printer, to achieve the balance of the
results of real-time printing. Test report form a single A4
format.

for HP-16 Measurement System for Balancing Machine
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.
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.
