Cooling towers are the heart of the factory mechanical system. If you use cooling towers in industrial systems, you need to know how to maintain them properly. Without this knowledge, energy costs will increase and equipment life will decrease. Regular cleaning and maintenance is required to prevent the growth of microorganisms and to keep the cooling towers in good condition. Dirty cooling towers, in addition to holding bacteria, can remove debris from pipes and reduce the efficiency of the entire system.
Why should we maintain a cooling tower ?!
Cleaning the cooling tower and purifying the water inside the system prevents damage to the entire system due to clogging and corrosion. Even if you purify the water regularly, you still need to clean the tower to protect the system from bacteria and germs. If you are evacuating your towers in the winter due to reduced need, schedule one of your two annual cleanups to get the most out of your system when refilling the tower when warmer conditions return. Even if you do not use the towers all year round, you should still schedule a two-year cleaning to prevent contamination that could damage the system.
If you have a new system, you should also clean and purify the water in your cooling tower. Transportation and assembly of tower components can damage or leave materials that corrode surfaces. Cleaning removes these materials from the surfaces and prepares the tower for purified water.
Things to do to maintain a cooling tower
Check your cooling tower at least once a month!
Sediment, lime and sludge can accumulate and contribute to the growth and development of Legionella bacteria. Regular inspections help determine when to schedule cleaning.
Clean the cooling tower tank surfaces!
If scale is visible, the tank needs to be cleaned, and the cooling tower vacuum cleaners will help you remove contaminants without shutting down or draining the system.
Descaling of filled materials
Filling the tower provides a breeding ground for bacteria, especially Legionella. A descaled dissolves the lime and mineral deposits that Legionella likes to hide and prepares the surface for cleaning.
Disinfect the tower
Cooling towers can be a dangerous place for bacteria to grow, so reducing the amount of nutrients available for bacteria to grow is important.
Do not forget these parts in the maintenance of the cooling tower!
1. Maintenance of cooling tower water purifier
The most important step in maintaining a cooling tower is a comprehensive monthly water treatment program. If water quality is neglected, it can contaminate the entire system and cause sludge in pipes and condensers.
If your company does not specialize in water purification, consult a company that specializes in this field. Make sure the water is tested monthly and purified with biocides and lime inhibitors. Automatic feeders and sensors must also be installed.
2. Engine maintenance
If your engine fails, it can damage the entire system. Because these engines are so heavy, lifting a new engine to the cooling tower is not the easiest thing to do. Things to do regularly:
- Inspection of windings and contacts (quarterly)
- Tighten all electrical connections (annual)
- Measure operating currents and voltages and make sure they do not exceed the recommended instructions on the motor plate (quarter).
- Check for excessive (monthly) vibration. Symptoms include worn bearings and unbalanced fan blades.
- Lubricate the bearing if necessary
- Check flexible motor parts (annually). If the engine is mounted on a rubber pedal, make sure it is not dry.
- Check the insulation of the engine (annually). If the insulation fails, water can enter the motor and cause a short circuit.
3. Cooling tower fan
Proper fan maintenance is also very important, as broken fan blades can damage bearings and cause other problems. so:
- Inspect blades and remove sediment (annual)
- Lubricating bearings and checking the latest game and wear (quarterly)
- Check the condition of couplings, pulleys and belts (quarterly)
- Belt replacement (annual)
- Corrosion and wear test (quarterly)
- Check fan alignment, balance and safety (annual)
4. Water inlet and water outlet
- Leak inspection and review (quarterly)
- Clean the filter if necessary
5. Spray nozzles
Clean the nozzles if necessary
6. pods
- Corrosion and wear test (monthly)
- Clean or replace if necessary
7. Floating valve
Corrosion and wear test (monthly)
