Package Type Industrial Counter Flow Open Loop Cooling Tower

Package Type Industrial Counter Flow Cooling Tower Open Loop Cooling Tower

1. Working Principle

This equipment is a mechanical ventilation cooling tower. Its working principle is to press the hot water to be cooled into the water sprinkling tank at the top of the cooling tower, and evenly and naturally sprinkle it on the filler through the fine holes. At the same time, the fan sucks unsaturated air from the air inlets on both sides of the tower. In the flow of the gap between the fillers, the hot water and the unsaturated air exchange heat, and the air transfers the heat to the outside and becomes hot air, which is then drawn out of the tower by the fan, thereby achieving the effect of lowering the water temperature.

3. Common Faults and Troubleshooting

Fault	Cause	Troubleshooting
Uneven water distribution (Trough type water distribution)	debris at the nozzle	Clear the nozzle outlet
Uneven water distribution (Trough type water distribution)	Nozzle falling off	Reinstall the nozzle
Outlet water temperature is too high	Excessive circulating water	Adjust water volume
Outlet water temperature is too high	Insufficient air volume	Adjust the blade installation angle, Check whether the packing or water collector is blocked
The fan has abnormal vibration	Mounting bolts loose	Re-tighten
The fan has abnormal vibration	Impeller is unbalanced	Check whether the installation angle deviation of each blade is within the specified range, recalibrate the static balance, and replace the transmission shaft.
The gearbox makes an abnormal sound The reducer is leaking oil	Gear wear	Changing gears
	Bearing damage	Replace bearings
	Gearbox lacks oil	Add 20#-50# industrial gear oil
	The oil seal of the new tower fails during the running-in period, and the oil pipe interface leaks oil	It is normal to run for one week. After one week of operation, the oil should be replaced with new oil. Check the oil seal to decide whether to replace it.
The fan blades make abnormal sounds	Fan blade card wind tube	Adjust the fan position
The fan blades make abnormal sounds	Loose fasteners and connectors	Check tightness
Cooling tower water leakage	Too much air volume	Adjust the fan
	Water collector damaged	Check the water collection system and replace damaged parts
Water splashing on the windshield	Water distribution overflow	Check the water distribution of the sprinkler
