Yingtai: Factors Affecting Service Life Of Centrifuge

A centrifuge utilizes centrifugal force to mechanically separate components of mixtures such as solids from liquids or immiscible liquids of different densities (e.g., separating cream from milk). Like any precision instrument, proper maintenance significantly extends its operational lifespan by three to five years. Experts emphasize several key aspects in maintaining centrifuges.

Daily maintenance of laboratory centrifuges primarily involves preventing contamination within the centrifugal chamber from dust and oil. Before and after each experiment, clean the chamber thoroughly using a lint-free cloth to remove oil residues, water vapor, sample leaks, and wipe down the bench-top. Avoid opening the chamber unnecessarily when not in use to prevent contamination. Ensure the seal of the chamber door is intact; apply vacuum seal grease periodically as the seal ages or loses elasticity.

Annually, conduct thorough maintenance and inspection of all internal systems of the centrifuge. Verify and clean suspicious components of the instrument, removing any accumulated debris or dust. For long periods of inactivity, periodically power on the centrifuge to maintain oil circulation and ensure the cooling system operates smoothly.

The centrifuge's drive system, including the high-speed motor, variable speed gears, rotating bearings, and sliding bearings, forms its core. Any abnormality in these components can disrupt the instrument's operation.
