DYNAMIC BALANCING MACHINE MODEL- HDCM

 
DYNAMIC BALANCING MACHINE MODEL- HDCM
 
 Machines 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. These machines are very simple in
 design. No. drive coupling/ adaptor etc. required to connect to the rotor to be balanced. It has
 following advantages

 1) Coast saving on manufacturing of precision adaptor to connect drive coupling to rotor.
 2) Any rotor can be balanced without loosing time in manufacturing of adaptor.
 3) The balancing accuracy of rotor not disturbed due to unbalance in drive coupling / adaptor
 4) Belt drive machine are more accurate (about 5 times) as compared to end drive machine.

 The machines features 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 “ features of measuring panel
 HDCM-8500”

 
 STANDARD FEATURES
 1) 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.
  

 2) Digital display for RPM indication
 A DPM is provided to indicate balancing speed continuously as a standard feature.
  
 3) Auto Stop
 No necessity to stop machine once started. It stops automatically after stabilization of
 unbalance results.

 4) 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.

 5) 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.

 6) Tolerance Indicators
 Separate LEDs are provided for both planes which glow when unbalance is reduced within
 balancing tolerance.

 7) 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.
 

 8) 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.

 9) 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 :

 • Drill attachment 8mm capacity portable drill With supporting overhead railing.
 • Separate drilling attachment 19mm. Capacity with a vertical drilling head , manual.
 • Portable type reverting hammer (piston type) speed 1800 blows/minute, capacity 6mm in a
 
  aluminum suspected from top with rail.
 • Tangential belt drive, in addition to standard (suitable for a particular type of rotor for
    production balancing)
 • Longitudinal movement of right hand pedestal by chain & sprocket attachment.
