Storing spare pumps in a pumped hydro storage system requires careful consideration to ensure they remain functional when needed. Here are some best practices tailored for these types of systems, combining general pump storage guidelines with the unique aspects of pumped hydro:
Best Practices for Storing Spare Pumps
1. Dry Storage Environment
Store pumps in a dry, room temperature environment to prevent humidity and condensation from causing corrosion.
2. Shaft Rotation
Rotate the shaft every 30 days to prevent bearings from developing flat spots and mechanical seals from sticking.
3. Rust Protection
Apply a rust inhibitor to exposed metal parts. Products like LPS-3 can form a protective film that prevents moisture and corrosion.
4. Avoid Extreme Temperatures
Ensure the storage area is away from extreme temperatures and vibrations, as these can damage the pump’s materials.
5. No Oil During Storage
It is generally best to store pumps dry rather than filling them with oil, as oil can separate or freeze in cold conditions, causing damage upon installation.
6. Elevation and Safety
Elevate the pump slightly to protect it from ground moisture and ensure it is positioned away from flammable materials and out of reach of children and pets.
7. Pre-storage Cleaning and Maintenance
Clean the pump thoroughly before storage and replace any worn-out parts to ensure the pump is in good condition when needed.
8. Lubrication and Air Circulation
Lubricate moving parts to prevent sticking and ensure good air circulation around the stored pump to prevent moisture buildup.
By following these practices, spare pumps in a pumped hydro storage system can be maintained effectively, ensuring they are ready for immediate use in case of emergencies.
