Tower Maintenance
Always shut off electrical power to the tower fan motor prior to performing any
inspections that may involve physical contact with the mechanical or electrical
equipment in or on the tower. Lock out and tag out any electrical switches to
prevent others from turning the power back on. Service personnel must wear
proper personal protective clothing and equipment.
Well-maintained equipment gives the best operating results and the least maintenance
cost. SPX recommends setting up a regular inspection schedule to insure effective, safe
operation of the cooling tower. Use the schedule on page 17 to obtain continuously
good performance with the least tower maintenance. See
Cooling Tower Inspection
Check List
in this manual. Keep a continuous lubrication and maintenance record for
each cooling tower.
HOT WATER DISTRIBUTION SYSTEM
–Keep the circulating water and distribution
system (piping and nozzles) clean and free of dirt, algae, and scale. Algae and scale
may clog nozzles, eliminators, fill, and piping, and may collect on the equipment served
thus reducing its performance.
An access hatch in the fan deck with ladder to an intermediate platform provides means
for inspection of the plenum area above the eliminators. Removal of an access hatch at
the plenum level allows access to the spray chamber for inspection and maintenance
of the nozzles and top of fill. Provide surface protection before walking on the fill.
DRIFT ELIMINATORS
–Eliminators should be kept clean.
Do not walk or step on the eliminators without planking and safety harness.
COLD WATER COLLECTION BASIN
(supplied by others)–Inspect collection basin
occasionally for leaks and repair if necessary. Keep cold water outlets clean and free
of debris. Makeup and circulating water controls must operate freely and maintain the
desired water quantity in the system.
DRIVESHAFT
–Check drive shaft alignment and condition of couplings every six
months. See the Drive Shaft User Manual for correcting misalignment, balancing, or
replacing parts.
FAN MOTOR
–Lubricate and maintain each electric motor in accordance with the
manufacturer’s instructions. If repair work is necessary, contact the nearest represen-
tative of the motor manufacturer. See Warranty Section of the Marley “
Fan Motor”
User Manual.
Fan motors with sealed bearings do not require lubrication maintenance.
