Common Problems of Centrifugal Pump Impeller
Published:
Jan 31,2024
The centrifugal pump impeller is one of the very important accessories in industrial chemical pumps. The normal operation of the centrifugal pump is inseparable from the cooperation of the impeller. However, after the centrifugal pump is used for a long time, the impeller will also have various problems.
The centrifugal pump impeller is one of the very important accessories in industrial chemical pumps. The normal operation of the centrifugal pump is inseparable from the cooperation of the impeller. However, after the centrifugal pump is used for a long time, the impeller will also have various problems.
Common Problem
1.Clogging: The pumped fluid accumulates in the casing, reducing clearance and pump efficiency, resulting in reduced flow and pressure.
2. Chemical corrosion: Corrosion Liquids or chemicals that are incompatible with pump materials can cause corrosion and failure of parts.
3. Cavitation: When the suction pressure is insufficient, bubbles will form inside the suction. The bubbles will collapse on the impeller surface and then implode, rapidly eroding a large area and causing failure. Impeller cracked due to cavitation
4. Unbalanced: All impellers are balanced during the manufacturing stage. If these are unbalanced, this results in unequal radial forces and associated accelerated component wear due to severe vibration. This directly affects the service life of mechanical seals and bearings, leading to premature pump failure.
5.When vibration occurs within the unit, the impeller may become loose. This can therefore lead to components coming into contact with the wear ring or high speed pump casing, resulting in damage to the unit.
6.Resonance: By installing a variable speed drive it can be assumed that the pump can be operated at any speed. Some RPMs can resonate within pump components, causing vibration.
