Maintenance Of Cooling Towers

Chemicals in water is measured by a pit factor. The scale of the pll from 1 to 14, acid solution specified in 1 to 7. The main condition specified in the 8 to 14. Chemicals can be added to the water to create a pH of 7 or 8 in the water.

Water temperature is important when testing for pH (acidic or basic). The warmer the water, the more active reaction of sensors or color testers. It is best to test the waters between 70GF and 80F (21C to 27C). Water almost to the boiling point is about 15% more active. Very cold water (almost to zero) will testify about 5% below the real value.

Chemicals can be used to reduce algae, fungi and slime growths. Deposits may be removed by scraping or with the help of a weak acid solution. After this, rinse with a solution of soda and wash. Water cooled condenser must be protected from freezing. Electric heater or automatic drain provide such protection.

When you turn off the water cooled condensing unit, the condenser coil must be fully exempt from the water. This is important if the device is exposed to freezing temperatures. This can be done by blowing with coils air, nitrogen, carbon dioxide. Should not exceed 60 pounds per square inch (75 psi, kPa to 449 518 kPa) pressure, or the system may be damaged.

Water drain valves should be left open. This will allow drainage of residual water in the pipeline. Make sure that drain the coolant circulation pump is removed and escaped.

The tower need regular maintenance. Once a year, repair of corrosion spots. It is a good practice to make the next month:

• Inspect the fan and motor bearings and oil sleeve. Grease (with water inhibitor} ball bearing.
• Inspect the belt tightness and alignment, and adjust it if necessary.
• Clean the filter.
• Clean and wash pump.
• Check the water level; adjusting the float, if necessary.
• Check the injector and clean if necessary.
• Check the water level is tight; it should work.
• Inspect the air inlet screens and clean if necessary.
• Inspect to algae, leaves or other dust particles.

All lines of influence of negative temperatures must be insulated and heated. Heating tape can be used. Most outdoor air-cooled condensers, cooling towers and evaporative condensers use a motor-driven fans. Engine bearings, belts, fan bearings are exposed to a wide changes in temperature, moisture and dirt. Bearings require special grease that will not wash out in conditions of high humidity. Silicone oils and fats are adequate. The same lubricants are also good for ice generators, water pumps, hydraulic pumps for heating systems. A good city water systems water is transported about 120 parts per million (ppm)of dissolved solids. This water can be thrown across the tower only about six times. After this scale will start to form. For this reason, most of the water should be treated. Furthermore, there should be a bleed-off device to keep the evaporating water purification systems.

Water that evaporates must be in the form of steam. Small droplets of water are exhausted from the cooling tower contain solids, adding to air pollution. One of the new ways of treatment of water electrostatically. The device provides the raw water, electric power. Power disconnects the scale of formation of the chemical. The loosened the bonds prevents scale formation and prevent impurities from the Association. He even not diminish the scale of already formed on the metal surfaces.

Fundamentals of the theory of water treatment is to reduce the content of ions in water. Tt should be reduced to a condition when salts and foreign objects, are electrically neutral. The material is then remain in the solution. Electrostatic treatment should be adapted to the raw water condition. Elech'ical instrumentation and chemical analysis are used to determine adjust...
