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 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 -
Cost saving on manufacturing of precision adaptor to connect drive coupling to rotor.
Any rotor can be balanced without losing 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.
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 feeding of rotor with 1 digit accuracy for its dimensions like A, B, C, R1 & R2. Tolerance limits of both correction planes i.e. 11 & 12 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”
Digital display for unbalance indicationAmount and angle for unbalance for both planes displayed on separate DPMS. Hence linear accuracy is very good as compared to Analog meter. Accuracy ±1 Digit for amount and ±1 Degree for angle.
Digital display for RPM indicationA DPM is provided to indicate balancing speed continuously as a standard feature.
Auto StopNo necessary to stop machine once started. It stops automatically after stabilization of unbalance results.
Simultaneous IndicationAmount 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-boardData of rotor dimensions and balancing tolerance i.e. values of A, B, C, R1, R2, tl1, tl2, are fed by key operation. Hence accuracy of data feedings accurate upto 1 digit.
Tolerance IndicatorsSeparate LEDS are provided for both planes which glow when unbalance is reduced within balancing tolerance.
Auto-rangeDepending 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 StoreData 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 CheckPanel is provided with “Self-Check” mode which checks proper functioning of digital displays, LEDs is cyclic operation. This helps immediate fault detection.
