The normal use of Centrifugal pump requires some attention. To ensure efficiency and usage time. The following introduction is for users' reference.
1. Right Priming of Centrifugal pump
A Centrifugal pump must always be primed before startup to avoid dry running, which can damage seals and impellers. Ensure the pump casing is filled with liquid to create necessary suction pressure.
2. Avoid Cavitation
Monitor inlet pressure to prevent cavitation—a destructive phenomenon caused by low pressure forming vapor bubbles. Maintain adequate NPSH (Net Positive Suction Head) and check for clogged filters or undersized pipes.
3. Gradual Startup/Shutdown
Sudden power surges strain the motor and impeller. Start and stop the Centrifugal pump slowly, especially in high-pressure systems, to reduce mechanical stress.
4. Regular Maintenance of Centrifugal pump
Inspect bearings and lubrication systems to prevent overheating.
Check alignment between the pump and motor to minimize vibration.
Replace worn seals promptly to avoid leaks.
5. Operational Limits
Never operate a Centrifugal pump beyond its rated flow or pressure. Overloading accelerates wear, while running at extremely low flow can cause overheating.
6. Material Compatibility
Ensure the Centrifugal pump construction materials (e.g., stainless steel, cast iron) are compatible with the fluid’s properties (e.g., corrosiveness, abrasiveness).
7. Emergency Preparedness of Centrifugal pump
Install pressure relief valves and alarms to detect failures. Train personnel to respond to leaks, unusual noises, or performance drops.
By adhering to these practices, Centrifugal pump can deliver reliable, long-term service across industries.
