Cooling Tower Gearbox Maintenance and Fan Setup
Synergy Services carried out corrective and preventive mechanical work on a the petrochemical site cooling-tower fan drive after a gearbox oil-seal issue was identified.
The public scope is intentionally limited to the maintenance method rather than plant-specific mechanical dimensions or detailed performance figures.
Work scope
- replace the damaged high-speed gearbox oil seal;
- service the flexible oil line and gearbox air vent;
- renew gearbox lubricant;
- inspect drive-shaft and coupling condition;
- check fan blade pitch, tip clearance and tip tracking;
- standardise fan-blade setup;
- recheck the mechanical system after assembly; and
- carry out airflow verification to support follow-up engineering assessment.
Why mechanical setup matters
Cooling-tower fan performance depends on the complete drive train, not only the gearbox. Oil leakage requires corrective work, but fan geometry and alignment also affect airflow, absorbed power and vibration.
For that reason, the service combined gearbox repair with fan setup and measurement rather than treating the oil seal as an isolated component.
Outcome
The documented defect was repaired, the lubrication path was serviced, and the fan setup was checked and adjusted. Airflow testing was then used as an engineering follow-up to compare operating behaviour and identify whether further optimisation should be considered.
Detailed equipment tags, alignment dimensions, torque settings and measured airflow/power tables remain in the internal service report and are not reproduced on the public page.
