Special rotor balance process
LARGE FAN ROTER END DRIVE
HARD BEARING BALANCER
This machine is a permanent hard support balancing machine-----
It is not necessary to recalibrate rotors with different shapes and weights.
The magnitude and angle of unbalance can be measured at one start.
Yfw-160 fan impeller balancing machine is a kind of balance machine
specially designed and manufactured by our factory for the fan manufacturer.
The machine is designed as horizontal hard support and universal joint
This machine can fully meet all the specifications of the General balancing
machine, only check the special technical parameters and safety parameters
according to the large diameter and large inertia. This machine can run
safely and frequently for a long time and operate with high intensity.
The mechanical system parameters of the machine are optimized according to
its frequent start-up.
Meet the technical requirements of JBT9101-2014 fan rotor balance:
It is also feasible and operable for the balance of externally suspended
Data memory and after shutdown can see the static balance value, and even
This machine adopts hp16 hard support balancing machine. The computer
electrical measuring system is a special computer system for permanent
standard setting. The core sampling CPU is a 32-bit industrial computer,
which can be used for high-speed dynamic AC sampling. The digital optimized
dynamic filtering of parameters can be set.
In the use of balancing machine, there is an efficient working mode: it is
not necessary to recalibrate rotors with different shapes and weights, and
the magnitude and angle of unbalance can be measured at one start.
It only needs to start once, and the parameters can be input after
As long as you measure the data stably, press the memory key to memorize the
data. Then the customer needs different calculation results, you can input
the corresponding a, B, C, R1, R2 parameters, and get the corresponding
calculation results immediately. Moreover, the calculation parameters can be
changed at any time, and the calculation results after change can be
It is possible to input even parameters, such as R1 A, B, R2, C, and so on.
It can also be input later or modified at any time. The electric measuring
box will change the value corresponding to the new parameter at any time.
SD card or TF card is used to store the test result report. 1000 report
records, and report records. It can be flexibly moved to PC for direct
The mechanical and electrical energy exchange device of this machine adopts
piezoelectric sensor. Since there is no mechanical movement, the failure
rate is very low, and the low-speed performance is good (the minimum speed
of the machine can reach 80 RPM). The measurement part of the balance
machine adopts the closed type force sensor, which has the advantages of
non-collision, high sensitivity, durability and good low-speed measurement
performance. In addition to the characteristics of general horizontal hard
support balancing machine, three important parameters are given for the
balance characteristics of fan impeller.
First, the maximum balance rotor diameter is 1100 mm
Second, it adopts 4 kW motor and vector inverter control.
Third, the maximum rotor mass is 160 kg, which can ensure that most of the
dimensions can be detected with the highest sensitivity, which is suitable
for the impeller of the machine.
These three parameters determine the wide adaptability of the machine in the
fan manufacturing industry.
