Progressive cavity pumps are widely used in industrial production for conveying high-viscosity, solid-containing media. Teffiko, with years of experience in fluid equipment, offers insights into their maintenance to ensure stable operation.
Monitor flow, pressure, speed, and motor current. Fluctuations may signal medium changes, blockages, or wear; high current indicates jams/overloads. Check vibration with detectors—abnormalities from misalignment or bearing damage require shutdown. Listen for odd noises (friction/impact) indicating wear or poor lubrication.
Maintain lubrication: Check oil level/quality; replace oil per schedule. Grease bearings appropriately. For seals: Adjust mechanical seal bolts for minor leaks, replace elements if severe. For packing seals, ensure slight leakage (few drops/min) for lubrication. Daily exterior checks: Fix leaks and keep the pump clean.
Long shutdown: Empty and clean the pump, rust-proof exposed parts, and hand-turn regularly to prevent component adhesion.
If medium properties (viscosity, corrosiveness) change, adjust parameters or replace suitable components. For sudden failures (motor burnout, jamming, pipe rupture), stop the pump, cut power/medium, fix issues (replace parts, clear debris), and analyze causes.
Maintenance staff must be professional and follow procedures. Shut down, cut power, and post warnings before work. Use protective gear for hazardous media.
Use matching parts, ensure correct installation. Keep records (time, work done, parts replaced) for tracking.
Proper maintenance ensures efficiency, reduces costs, and extends life. Teffiko provides one-stop services with 24-hour response, quality parts, expert engineers, and full after-sales support. Contact us for cooperation!
