Basic principles to be paid attention to when selecting a cooling tower

Basic principles to be paid attention to when selecting a cooling tower:

1.According to the temperature of the cooled water, the cooling tower selection includes: high temperature tower, medium temperature tower, and normal temperature tower.

2.According to the current situation of the installation location and the requirements for noise, the selection of cooling towers includes: cross flow tower and counter flow tower.

3. Select the cooling water volume according to the cooling water volume of the water chiller. In principle, the water volume of the cooling tower should be slightly larger than the cooling water volume of the water chiller.

4.When selecting multiple water towers, try to choose the same type of cooling tower.

Key points to pay attention to when selecting a cooling tower:

1.The structural material of the cooling tower body should be stable, durable, corrosion resistant, and assembled in coordination.

2. Uniform water distribution, less wall flow, reasonable selection of splashing device, not easy to block

3. The type of cooling tower filling material meets the requirements for water quality and temperature.

4. Fan matching can ensure long-term normal operation without vibration and abnormal noise, and the blades have good water erosion resistance and sufficient strength. The installation angle of the fan blade can be adjusted, but it is necessary to ensure that the angle is consistent and the current of the motor is not higher than the rated current of the motor.

5. Low power consumption, low cost, small and medium-sized steel frame glass cooling towers also require light weight.

6. The cooling tower should be avoided to be arranged near heat sources, waste gas and flue gas generation points, chemical stacking areas, and coal piles.

7.The distance between cooling towers or between towers and other buildings should not only consider the ventilation requirements of towers and the interaction between towers and buildings, but also consider the distance between buildings for fire prevention and explosion prevention, as well as the construction and maintenance requirements of cooling towers.

8.The direction of the water inlet pipe of the cooling tower can be rotated by 90 °. 180 °. 270 °.

9. The material of the cooling tower can withstand a low temperature of - 50 ℃, but it should be stated when ordering in areas where the average temperature of the cold month is lower than - 10 ℃, in order to take anti icing measures. The cost of the cooling tower will increase by approximately 3%.

10. The turbidity of circulating water should not be greater than 50mg/l, and should not be greater than 100mg/l in the short term. It should not contain oil and mechanical impurities. If necessary, measures should be taken to eliminate algae and stabilize water quality.

11. The water distribution system is designed based on the nominal water volume. If the actual water volume differs from the nominal water volume by more than ± 15%, it should be stated when ordering in order to modify the design.

During storage and transportation of cooling tower components, no heavy objects shall be placed on them, no sunlight shall be allowed, and attention shall be paid to fire prevention. During the installation, transportation, and maintenance of the cooling tower, open flames such as electricity and gas welding shall not be used, and fireworks shall not be set off nearby.

13. Round tower multi tower design, the clear distance between towers should be maintained not less than 0.5 times the diameter of the tower body. Cross flow tower and counter flow square tower can be arranged in parallel.

14. The selected water pump should be matched with the cooling tower to ensure process requirements such as flow rate and head.

15.When selecting multiple cooling towers, try to choose the same model as much as possible.
