Are you aware of the sensitivity and precision of the balancing machine?

Balance machine sensitivity and accuracy that we are no stranger, many people at work time need to test to see if it meets the standard, but we have a lot of people at work time to find the general so-called instrument accuracy, for the Amplitude error, the commonly used indicator or full scale percentage to represent, and the phase error common degrees that.

However, for a balancing machine, balancing machine if the correction is performed in accordance with the unbalance indication indicated by the above precision and the permissible residual unbalance of the rotor is within a certain limit, for a rotor with a large initial imbalance, this The error appears too strict, and the initial imbalance of the rotor is small, this error is very loose.In addition, even if there is a certain amplitude, phase error,

If the number of corrections is increased, the amount of residual unbalance is gradually reduced within a certain limit, but can not be reduced after reaching a certain limit.balancing machine On the other hand, the so-called sensitivity is the amount of unbalance that must be applied to increase the indication of the instrument , The above values vary with rotor mass.

In the light of the above, balancing machine the International Organization for Standardization has recently established a methodology for assessing the performance of baluns, which uses the specified calibration rotor and tests according to defined procedures. The results are expressed as a minimum reachable residual unbalance and an unbalance reduction rate The
