YYW-16000A Balancing Machine

Low-speed balancing machines below 80 rev / min

Balancing Machine 7000mm large diameter

 

The main technical parameters:

A. rotor mass range: .................................................. 500-16000 kg

B. Maximum rotor diameter (excluding trench dimensions): .... Φ4200 mm

Maximum rotor diameter (included trench dimensions): .......... Φ7000 mm

C. support length range: .......................................... 4100-7400 mm

D. supporting shaft diameter range: .................................... 90-320 mm

E. Balancing Work speed: .......................................... 70-1000 rev / min

F. Motor power (inverter motor): ....................................... 75 kilowatts

G.. Minimum achievable residual unbalance: ............... Q 1 gram. Mm / kg

H. once unbalance reduction ratio .................................... R 90%

 

Reduction ratio greater than 10-fold, the largest car factory gear box (FAW) products, to ensure its mechanical transmission, low noise.

Can balance the nation's largest cement separator rotor, the figure is a   cement mill separator, diameter greater than 5 m. The machine working speed: 85 rev / min for process balance. Beijing Power Equipment Plant produces maximum rotor diameter is 6500mm.

The balancing of the powder cement.

The machine is in North China's largest existing working diameter balancing machine.

 

A. driving part adopts 75 kilowatts inverter motor supporting machinery with stage transmission scheme can achieve optimal power output. Inverter using ABB or Siemens products, use the Beijing Motor Plant inverter motor or equivalent level of quality products;

B. sensor uses the company's own production of solid sensor, the sensor by users prove their failure rate is almost zero;

C. Measurement vector solvers computer, digital display form.  This machine has the following characteristics:

 

   HP-16 hard bearing balancing machine computer electrical measurement instrument is a balanced machine dedicated computer: high reliable industrial computer chip circuit, direct 220VAC power supply, strong anti-interference, adaptation to unstable power supply conditions, for the unstable speed can also be measured. Software vector solution measurement data, large font digital display. Overall 4 digit display input parameters, a key indicator of static balance, can be set parameters of the data stability.

  The measured data can be processed and processed after shutdown: the different parameters can be transformed, and the measured results are more consistent with the actual measurement results. The operator if you need other parameters of the solution results, you can enter the corresponding parameters, the corresponding calculation results. Once again change the calculation parameters, the same can be directly obtained after the change of the calculation results. No need to boot the measurement again.

  Automatic (or manual) memory while driving the engine shutdown function, customer self calibration function, recovery of the factory calibration function, sensor signal line fault judgment and indication function.

 

D. The test results report and report single electronic document records, can be output to the SD card or TF card.

E. fuselage sub-structure. Between the two sections of the fuselage length 3.5 m trench opened to accommodate large-diameter rotor (see outline drawing host).

 

F. Compensation and correction method for process mandrel and electric measuring box with bending damage:

When the balance process shaft is used for a long time, it will bend. When the bending degree is greater than 0.05 mm, the balance result can not meet the technological requirements.

If the value is too large to correct the unbalance, press the "initial unbalance key", press the "storage key" after the data is stable, turn the rotor over 180 degrees relative to the process axis after shutdown, slowly start the balancer, press the "180 degrees unbalance key" and press the "storage key" after the data is stable. Then press "secondary compensation 2" to compensate for 2 transposition. Such measurement results will eliminate the errors caused by the bending of the balance axis.
