Points to pay attention to when selecting cooling towers

发布日期:2021-03-31 浏览次数:786

  The basic principles that should be paid attention to when selecting the cooling tower:

  1.According to the temperature of the water to be cooled,the cooling tower options include 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 cooling tower options include a cross-flow tower and counter-flow tower.

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

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

  The key points that should be paid attention to when selecting the cooling tower:

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

  2.Uniform water distribution.Less wall flow.Reasonable selection of splashing devices and not easy to be blocked.

  3.The type of cooling tower water spray filler meets the requirements of water quality and water temperature.

  4.The fan is matched to ensure long-term normal operation without vibration and abnormal noise,and the blades are resistant to water erosion and have sufficient strength.The installation angle of the fan blades is adjustable,but the angles must be 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 lightweight.

  6 Cooling towers should try to avoid placing them near heat sources,waste gas and flue gas generating points,chemical storage places,and coal piles.

  7.For the distance between cooling towers or between towers and other buildings,in addition to considering the ventilation requirements of the tower and the interaction between the tower and the building,the fire protection,an explosion-proof distance of the building,and the construction and maintenance requirements of the cooling tower should also be considered.

  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 the low temperature of-50℃,but it should be stated when ordering the areas where the average temperature of the cold month is lower than-10℃,to take anti-icing measures.The cost of cooling towers increased by about 3%.

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

  11.The water distribution system is designed according to 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 to modify the design.

  12.During the storage and transportation of cooling tower components,no heavy objects should be placed on them,no exposure to the sun and fire prevention should be paid attention to.During the installation,transportation,and maintenance of the cooling tower,no open flames such as electricity,gas welding,etc.shall be used,and no firecrackers shall be set off nearby.

  13.In the design of multiple towers with round towers,the net distance between the tower and the tower should be kept at least 0.5 times the diameter of the tower body.Cross-flow towers and counter-current square towers can be arranged side by side.

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

  15.When choosing multiple cooling towers,use the same model as much as possible.
