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 |
| Nozzle falling off | Reinstall the nozzle | |
| Outlet water temperature is too high | Excessive circulating water | Adjust water volume |
| 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 |
| 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 |
| 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 |
