SPECIFICATION TABLE

Fan impeller balancing machine factory is specially designed for the manufacture of wind turbine manufacturing industry as a balancing machine

 

 Features: Drive power to consider the user to determine the specific circumstances of the rotor, instead of asking the user wants more power.   To get the user to use the maximum rotor parameters, balancing machine manufacturers calculate how much the driving power in order to meet the measurement requirements.   Balancing machine drive power and has a cross-parameter measurement system, is to measure speed and drive speed.

  If you start measuring measuring system is 200rpm, then you have to meet this requirement the drive system.

  For example: 2000kw speed of a fan if the work is 500rpm, 200rpm when it is running to 128kw.

 And 140rpm is 43.9kw

 So one can measure the speed of the measurement system, large fan balancing machine is a prerequisite.

 

 Calculated using the computer for data processing.  External Universal Desktop Computer (XP system) for automatic data recording, processing print test reports.

1  A driving power is larger.

2  measuring low speed 60 rev / min to start measuring

3 large working diameter (fan characteristics).

4 Heavy balancing machine (greater than 10 tons) of the support rollers must meet the workpiece axis maximum contact pressure conditions (to meet the direction of positive pressure flexible working range to avoid contact with the surface of the fatigue damage). That is the work of wheel diameter must be large enough, we can ensure that the contact area is large enough. Otherwise it will hurt the customer's product-axis (fatigue bruised, crushed and plastic deformation).

5 Overload larger (double), rigidity of the overall measurement beam steel, linearity remains greater than the maximum mass of more than twice.

6 with a brake function, especially in large balancing machine.Large inertia of the rotor parking continuation in about 20 minutes.There are 1-3 since the beginning of the braking function can stop.

7 How large balancing machine stage gearbox (4-5 stage reduction more than 6 times)

8 large balancing machines Reversible double balance function can be implemented to facilitate the user's special rotor balancing
