1. As the cooling water circulation pump manufacturing process, but off: the rotor imbalance; pump and motor shaft is not the heart; the rotor and the stator part of the collision or friction;
2 due to the use of longer, circulating pump wear aging: impeller loose; bearing damage or bearing clearance large;
3. Circulation pump inlet pipe, the impeller, the pump debris; circulating pump and the foundation is not fixed, the phenomenon of resonance to strengthen and so on;
4. Cooling water circulating pump work to promote water flow, accompanied by eddy currents, cavitation will inevitably produce vibration;
From this, we can conclude that there are many reasons for the circulating pump to vibrate, and it is inevitable that some of the many vibrations generate several times. This requires us to deal with the issue of circulating pump vibration in addition to the circulating pump itself to enhance the manufacturing process to reduce the vibration amplitude, through to the circulating pump installation of rubber vibration isolators, spring isolators, inertia base has become a cooling water circulating pump vibration control important method.
