If your measurement system starts measuring at 200 rpm, then your drive system meets this requirement.
For example: 2000kw a fan if the working speed is 500rpm, then it runs to 200rpm when it is 128kw.
And 140 rpm is 43.9 kW
So a measure of low-speed measurement system, is a large fan balancing machine necessary conditions.
The same time as
1 drive power is large.
2 measuring speed low 80 r / min to start the measurement
3 larger working diameters (fan characteristics).
4 heavy duty balancer (greater than 10 tons) of the support roller must meet the maximum contact pressure conditions of the workpiece axis (to meet the positive pressure direction of the elastic working range, in order to avoid contact with the surface fatigue damage). That is, the working diameter of the roller must be large enough to ensure that the contact area is large enough. Otherwise it will hurt the customer's product axis (fatigue crush, and plastic deformation crush). The roller bearing of the machine adopts 6413 specifications, the maximum can withstand 50 tons of load.
5 overload capacity (twice), the overall measurement of stiffness beam, linearity to maintain more than twice the maximum quality.
6 has a brake function, especially a large balancing machine. Large inertia of the rotor will continue in about 20 minutes. A brake function can be parked within 1-3 minutes.
7 large-scale balancing machine has a multi-stage gearbox (4-5 level deceleration of more than 6 times)
8 large-scale balancing machine can be implemented in both positive and negative balance function, to facilitate the user's special rotor balance
The same time as
YFW-20000 fan impeller balancing machine is the factory for the fan manufacturing industry specifically designed and manufactured a balancing machine.
The machine is designed for horizontal, hard support, universal joint drive.
