Dynamic Balancing Machine

Product Details:

BIE make hard bearing type horizontal two plane Dynamic Balancing Machine with microprocessor-based / microcontroller based measuring panel. Machine Model FBM-(M) is Most suitable for balancing of different types of rotors like rotors of Electric machines, Flywheels, Crankshafts cylinders, Submersible pump rotors, etc. Working on these machines is very simple. Double start push button is provided to start the machine. The cycle is fully automatic which starts the machine, measures and stores the unbalance in grams (gms) along with the angle for two selected planes on digital display simultaneously & stops the machine (with brake if the machine is provided with electrical braking facility). The measuring cycle takes around fifteen seconds for smaller rotors For a higher capacity machine, the drive is provided through the motor. To avoid any damage to drive coupling and other rotating parts in the drive system, the electronic soft starter is incorporated with the machine. Keyboard facility is provided on measuring panel for data feeding of dimensions like Al B, C, RL & RR tolerance limits for both correction planes i.e. TLL, TLR can be fed so that when the rotor is balanced within specified limits, respective LED glows up, indicating no further correction is required. For more details please refer features of microprocessor-based / microcontroller based panel for dynamic balancing machines, To increase the capacity of the machine for extra long rotors. additional bed lengths can be provided, which can be aligned along with the basic machine beds. Facility for an additional bed with gap bed arrangement is also possible to accommodate bigger diameter rotor. Higher capacity machines above 7000 kg are provided with fixed separate drives and hence gap bed design is not possible for these machines.

Key Board:

• KKeyboardis provided for data feeding. Data of rotor dimensions like A,B ,C .RL and RR and balancing tolerances. TLL & TLR are fed by the key operation. Hence, the accuracy of data feeding is accurate upto 1 digit.

Digital Display:

• For unbalance Indication: Amount of unbalance along with angular position is displayed separately for both correction planes simultaneously. Hence angle & amount indications are more accurate and precise as compared to conventional analogue meters.

Digital display for speed indication:

• Four digit display is provided for indicating balancing speed in RPM as a standard feature.

Auto Stop:

• Machine once started. stops automatically after the unbalance readings are stabilized.

Simultaneous Indication:

• Amount and angle of unbalance in both planes is displayed simultaneously and remains stored till next run. This totally eliminates operation of plane selector switch and reduces the additional time required for unbalance stabilization.

Auto Range:

• Depending upon unbalance amount, fine or coarse range gets automatically selected till rotor gets balanced within tolerance limits. Multiplier operation (manual) is totally eliminated.

Tolerance Indicators:

• Separate LED's for both correction planes are provided which glow when unbalance is reduced within selected balancing tolerance.

Data store:

• Data for various rotors can be stored against respective rotor type nos. Hence no need of measuring rotor dimensions or rotor data feeding when balancing of the same type of rotor is to be carded out. Just call rotor type no and the machine is ready for balancing.

Product Details:

BIE make Strobo dynamic balancing machines are provided with belt drive arrangement and xenon flash tube for locating the position of unbalance in the rotor. The machines are very simple for operation and very high balancing accuracies are achieved. Machine Model SSBM - 1 / 3 is provided with specially developed electro dynamic pickups which sense minute vibrations in the rotor due to unbalance.

Salient features of machine Model SSBM - 1 / 3 are as follows:

• This is a very compact and tiny machine with high accuracy for balancing of small rotors.
• Special electro dynamic pickups are used for sensing minute vibrations due to an imbalance in the rotor.
• The machine is provided with electronic control panel with digital panel meter for amount indication and xenon flash tube with a brilliant white light for locating position of unbalance in the rotor.
• Rotor loading and unloading are very easy, as a special quality stretchable rubber belt is used for driving the rotor under trial.
• The machine is very sensitive and accuracies of the order of 0.2 microns can be easily obtained and small rotors can be balanced accurately.
• The machine does not require any concrete foundation. It can be operated by placing on a plain surface.
• The machine requires single phase supply of 220 volts, A.C., 50 Hz. As such a machine can be conveniently located where single phase supply is available.
• Operation of the machine is very simple and does not require any skilled operator, once proper training for operating the machine is given.

Application Flexible and Versatile:

• Vertical machine applications range from balancing in the repair workshop to fully automatic mass production. Manual, semi or fully automatic processes are available to meet the needs of any balancing requirements. These machines are most suited for balancing of disc type components like flywheels, clutch plate, impellers, etc.

Operationl Simpleand Logical:

• Many practical details in the design of our vertical balancing machines make operation easy. Low space requirements, ergonomic operation and easy loading can make these machines an integral part of your facility. Our vertical balancing machines are permanently calibrated to reduce set up time and eliminates the need for special calibration runs. Accurate indication in balancing unit avoids the necessity of complicated conversions. Moreover unbalance can be directly corrected on the balancing machine speeds up the working process.

For corrections of the unbalance in the barancing machines:

• Correction devices such as drilling head attachment or milling attachment, as per requirement of the customer can be integrated with the balancing machine to accelerate the productivity of the machine.
• Balancing and correction is a single operation means no unclamping and reclamping between measuring run and unbalance correction required increased accuracy.
• Ergonomic operation from a single position High operation
  Reliability.
• Robust mechanical design and durable electronic components for a long service life under severe operating conditions.
• Simple operation of machine and measuring instrument.
• Protection devices and sa{ety measures to ensure safety at work.

Measurementunits:
