Dynamic Balancing Machine model HDCM are belt driven
horizontal type photo scanning
Universal Hard Bearing Balancing
Machine, provided with
microprocessor based measuring panel
HDCM – 8500 suitable for balancing
different shapes of rotors, of
electrical machines, cylinders, fly
wheel, rotor of centrifugal pumps
and any other type of rotating
machines. |
|
|
|
Dynamic Balancing Machine are very simple in
design. No. drive coupling/ adaptor
etc. required to connect to the
rotor to be balanced. It has
following advantages |
|
|
| |
• Coast saving on manufacturing of
precision adaptor to connect drive
coupling to rotor.
• Any rotor can be balanced without
loosing time in manufacturing of
adaptor.
• The balancing accuracy of rotor
not disturbed due to unbalance in
drive coupling / adaptor
• Belt drive machine are more
accurate (about 5 times) as compared
to end drive machine. |
| |
|
|
features of Dynamic Balancing Machine is a very simple
operation. The working cycle is
fully automatic. From safety point
of view a double press push button
starts machine, Measures and stores
the unbalance values on DPMs for two
Plane simultaneously and stops
machine. Key board facility provided
in measuring panel for correct data
deeding of rotor with l digit
accuracy for its dimensions like A.B.
C, R1 & R2. Tolerance limits of both
correction planes i.e.t 11 & t12 can
be feed so that when rotor is
balanced within the limits
respective LEDs glow up, indicating
no further correction necessary. For
other details please refer “

STANDARD FEATURES |
|
|
|
|
Digital display for
unbalance indication |
| |
|
| |
Amount and angle of unbalance for
both planes displayed on separate
DPMs. Hence linear accuracy is very
goos as compared to analog meter +
/- 1 digit for amount and +/-1
degree for angle. |
| |
|
|
Digital display for RPM
indication |
| |
|
| |
A DPM is provided to indicate balancing speed
continuously as a standard feature. |
| |
|
|
Auto Stop |
| |
|
| |
No necessity to stop machine once started. It
stops automatically after stabilization of
unbalance results. |
| |
|
|
Simultaneous Indication |
|
|
|
Amount and angle of unbalance in both planes
displayed simultaneously and remains displayed
(stored ) till next run. This totally eliminates
operation of plane selector and reduces
additional time for stabilization of readings in
other plane. |
|
|
|
Key-Board |
|
|
|
Data of rotor dimensions and balancing tolerance
i.e. values of A,B,C,R1,R2, t11,t12 are fed by
key operation. Hence accuracy of data feeding
is accurate up to 1 digit. |
|
|
|
Tolerance Indicators |
|
|
|
Separate LEDs are provided for both planes which
glow when unbalance is reduced within balancing
tolerance. |
|
|
|
Auto Range |
|
|
|
Depending upon whether unbalance amount is more
or less a respective course or fine range gets
automatically selected till rotor gets balanced
within tolerance limits, Multiplier operation is
totally eliminated |
|
|
|
Data store |
|
|
|
Data of various rotors can be stored against
respective rotor type nos. Hence no need of
measuring of rotor dimensions or rotor data
feeding when repeat balancing operation
required. Just call rotor type no. and machine
is ready for balancing. |
|
|
|
Self Check |
|
|
|
Panel is provided with ‘self-check’ mode which
checks proper functioning of digital displays,
LEDs is cyclic operation. This helps immediate
fault detection. |
|
|
|
|
ADDITIONAL FEATURES ON DEMAND |
| |
|
| |
Printer : |
| |
|
| |
A matrix printer can be connected
through ‘FIE’ software. It shows
runs till rotor is balanced within
balancing tolerance. |
| |
|
| |
Component Indication : |
| |
|
| |
‘FIE’ software specially developed
with 3-99 component indication is
suitable for balancing of rotor with
fixed locations for balancing
correction. |
| |
|
|
Unbalance Correction : |
