How to judge the advantages and disadvantages of the rotor operating state in the work, the advantages and disadvantages of the rotor operating state is an important standard to measure whether the oil-free air compressor is normal, the factors affecting the rotor operating state are many, there are the following points:

1, rotor unbalance, rotor unbalance is absolute, can not be eliminated, the engineering usually uses the balance accuracy to distinguish the balance effect of the rotor。The higher the accuracy, the better the balance effect, and the smoother the running state of the rotor;

2, the wrong oil-free air compressor is generally a multi-rotor system, so there is a connection between the rotor and the problem of alignment, the alignment of the rotor is the core of the installation and maintenance of equipment, of course, is also the key to determine the operation of the equipment is good or bad, can not be ignored;

3, the unit's self-excited vibration rotor in operation due to internal friction, uneven airflow and oil film instability caused by vibration, such vibration is sometimes empty, and specific has great destructive power。

4, surge phenomenon Surge is the inherent characteristics of oil-free air compressor, when the gas flow is small to a certain extent, the compressor will appear surge phenomenon。The unit has strong vibration and loud noise during surge, which should be avoided。

The above four factors can aggravate the vibration of the rotor, and the rotor is usually judged by the vibration amplitude and vibration intensity as the standard。
