Fan vibration dynamic balance measuring instrument use method

If the fan vibration dynamic balance tester uses a high-sensitivity sensor, it can use a lower speed. In the maintenance industry, if you use a lower speed, the driver will often suspect the effect of the balance, so there is a trend to increase the speed. In the balance When the heavy-duty drive shaft is used, the speed of the hard-support balancing machine is generally low, and the driver easily suspects the effect of the balance, which leads to the best-selling balancer of the soft-bearing balancer.

The balance of the rotor vibration balance tester will show significant oscillations in practical applications. This is not caused by the imbalance of the rotor itself, but due to the difference in rigidity of the rotor bearing journals or the rotor layout. The occurrence of higher harmonics, the oscillations caused by electromagnetic encouragement, the effect of turbulence in the rotation process of the bladed rotor, and the resonance of the system. Because other equipment connected to the power grid frequently initiates the effects of power supply shake and noise or beat disturbances that occur due to the proximity of both the support roller and the rotor journal. The difference between the diameter of the roller and the workpiece journal should be greater than 20%.

Fan dynamic balance tester In modern machinery, due to the wide application of flexible rotors, flexible rotor balancing machines have been developed. This type of balancing machine must perform stepless speed regulation within the working speed range of the rotor. In addition to measuring the vibration or vibration force of the support, it can also measure the deflection of the rotor.
