Centrifugal pump used to find the pump vibration and noise anomalies, should be immediately shut down and check:
1. Pump foundation is reliable
When vibration occurs, should first check whether the bolts fastening the centrifugal pump. If not tightening will cause vibration of centrifugal pump. Also consider the foundation strength is enough, sometimes due to the design of the soft foundation, can also cause vibration.
2. Coupling to find the right
A lot of centrifugal pump is driven by coupling, the type of coupling is also a lot of. Conventional three jaw coupling to find the right or bad directly affects the coupling, shaft, bearing, seal and other normal operation and service life.
3. Looking for the center
Center is also a common cause of vibration, must be strictly in accordance with the standard will be adjusted within the scope of the provisions of the.
4. Bearing inspection
Bearing installation is a problem or whether it is damaged.
5. Rotor center position adjustment.
Pump rotor should be concentric with the stator, otherwise the pump will produce friction, resulting in vibration.
6. Shaft bending and rotor measurement
If you can not find the cause of the vibration outside, can only be the disintegration of the pump. First measurement, calibration shaft bending, there is no problem with the small rotor mounted, overall measurement of Akira, ladle side, if exceeded must be corrected.
7. Static and dynamic balance detection.
After dismantling the centrifugal pump, in order to avoid the vibration of the pump, the impeller should also be used as a static balance test.
