Machines Model HDM are horizontal type universal hard bearing
balancing machines provided with Microprocessor based measuring
panel HDM-8500 for balancing different shapes of rotors like rotors of
electrical machines, crankshafts, cylinders, Gas Compressors,
flywheels, turbine rotors, rotors of centrifugal pumps and any other type of rotors of rotating machines.
These machines feature 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 planes simultaneously and stops machine (with brake if machine is
provided with electrical braking facility). The measuring cycle in general is less than 10 seconds for normal rotors, which can be accelerated
within 5 seconds.
To have smooth and gradual acceleration models HDM 3,000/7,000/10,000/20,000 are provided with slip ring motors in order not to have damage to drive coupling as well other rotating parts in drive system like gears etc. The starting of these machines is done manually by cutting remittances of starter in 4 to 5 steps.
Key-board facility provided on 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. t1, and t2 can be fed, so that when rotor is balanced within the limits respective LED is glow up, indicating no further correction necessary. For other details please refer ‘Features of Measuring panel HDM-8500.’
The usable length of machine is established according to the longest
rotor to be balanced. Extension beds can be supplied on request, which
can be added to standard bed of machine. It is also possible to install an additional bed (Gap bed) with a pit between this bed and standard bed of machine in order to balance rotors having its outside diameter exceeding swing over standard bed. Models HD-7,000/10,000/20,000 are provided with fixed separate drives and hence gap-bed design is not possible.
This is a Microprocessor based measuring panel
suitable for FIE Hard Bearing Machine.
Additional Features on Demand :
1) Printer :
A matrix printer can be connected through available ‘FIE’
software. See sample printout. It shows trial runs till rotor
is balanced within balancing tolerance.
2) FIE Software specially developed for balancing of 2/4/6 throw crankshafts available on request.
