The amplitude of the vibration. The vibration detection technology is the most widely applied and most effective equipment monitoring technology in the actual field of engineering at present. The unbalance of the impeller in the slurry circulating pump can be diagnosed by using vibration detection; rotor bending, cracking; the shafting is not centered; friction of the movable and static parts; resonating; mechanically loosening; vibration due to fluid such as surge and turbulence, and failure of rolling bearings.
