Major Overhaul Case
Atlas ZH500-E
Model:
Atlas ZH500-E
Issue:
The unit has been shut down for three years and cannot be turned over; the control panel shows no display.
On-site condition:
The impeller is severely clogged with dust, and the bearings at stages one, two, three, and four show significant wear. The high-speed shaft bearing area is also worn, while the primary oil-gas seal exhibits minor wear, and the secondary and tertiary oil-gas seals are severely damaged. Additionally, the tertiary cooler is heavily blocked, leading to water leakage, and water has even entered the control panel.
Maintenance plan:
Clean and dynamically balance the impeller, repair the high-speed shaft bearing housing, replace bearings from stages 1, 2, 3, and 4, restore the oil-gas seals at stages 2 and 3, install a new stage-3 cooler, and refurbish the control panel.
Result:
The system was powered on for a trial run, and all operational data remained within normal ranges, confirming it’s safe to begin full-scale production.
