10 Questions
What does 'drift' refer to in the context of cooling towers?
Water particles becoming entrained with the flow of air leaving the cooling tower
What causes excessive water drift in a cooling tower?
Missing louvres that allow air to sweep rapidly through the tower
Why should drift be eliminated or reduced to a minimum in a cooling tower?
To reduce make-up water requirements
What can cause the outlet water temperature to rise in a cooling tower?
Water is supplied at too high a rate for it to splash and break up
How can over pumping contribute to excessive water drift in a cooling tower?
By overloading the tower’s fill and splash bar system
What could cause high temperatures in the cooling tower?
Blocked or impeded airflow into the tower
What is a potential cause of a tower fan motor overheating?
Blocked ventilation holes due to dirt or debris
What can happen if the oil level in the gear reducer system is insufficient?
The gearbox may seize and contaminate the water in the cooling tower
What could cause a loss of water flow in the cooling tower?
Scale and sediment breaking off in the pipes due to improper water treatment
What should be checked if a tower fan motor is making unusual noises?
Vibration of the motor at both ends
