What are the common fault about impeller?

The most common fault about impeller is a dynamic balance. It will cause some corrosion during the processing which causes losing the original balance and strong vibratory noise.Finally it will make the machine broken

The most convenient way is to tough and hear, if you want the better result, we can remove the rotor to the air blower factory.Or the motor repair company can just test bench and calibration with special test technology. Advanced detection instrument can do online testing, which will switch vibration sensors to the electrical signal to display,so that we can have a better report. The other common faults is Water pump leakage, we can change the packing or gland , it will be more intuitive. And it will be possible even if the impeller drop, of couse it will work without pressure. At last the high-speed rotational cause resonance problems such as centrifugal compressors.
