1. The structural material of the tower body of the industrial cooling tower should be stable. Durable. Corrosion resistant. Accurate assembly and coordination.
2. Water distribution is even. Less wall flow. Splash device selection is reasonable, not easy to block.
3. The type of cooling tower water drenching filler conforms to the water quality. Water temperature requirements.
4. Fan matching, can ensure long-term normal operation, no vibration and abnormal noise, and the blade water erosion resistance is good and has sufficient strength. The installation angle of the fan blade is adjustable, but the angle must be consistent, and the current of the motor does not exceed the rated current of the motor.
5. Low power consumption. Low cost, small and medium-sized steel frame glass cooling tower also requires light quality.
6. The cooling tower should be avoided in the heat source. Exhaust gas and flue gas generation point. Chemical dumps and near coal piles.
7. The distance between the cooling tower or between the tower and other buildings, the cooling tower in addition to considering the ventilation requirements of the tower, the tower and the building interaction, but also consider the building fire. Safety distance of explosion-proof and construction and maintenance requirements of cooling tower.
8. The direction of the water inlet pipe of the cooling tower can be rotated at 90 °, 180 ° and 270 °.
9. The material of the cooling tower can withstand the low temperature of -50 ℃, but it should be explained when ordering for areas where the average temperature of the cold month is lower than -10 ℃, so as to take anti-icing measures. The cost of the cooling tower increased by about 3%.
10. The turbidity of circulating water is not more than 50mg/l, and the short-term turbidity is not more than 100mg/l. It should not contain oil and mechanical impurities. If necessary, algae control and water quality stability measures should be taken.
11. The water distribution system is designed according to the nominal water quantity. If the difference between the actual water quantity and the nominal water quantity is more than 15%, it should be explained when ordering so as to modify the design.
12. During the storage and transportation of cooling tower parts and components, no heavy loads or exposure shall be allowed on them, and attention shall be paid to fire prevention. Cooling tower installation. Transportation. Do not use electricity during maintenance. Gas welding and other open flames, near not allowed to set off firecrackers fireworks.
13. Round tower multi-tower design, the net distance between the tower and the tower should be kept not less than 0.5 times the diameter of the tower body. Cross-flow column and counter-flow column can be arranged in parallel.
14. The selected water pump should be matched with the cooling tower to ensure the flow, lift and other process requirements.
When choosing multiple cooling towers, choose the same model as much as possible.
Today's small series to introduce the cooling tower installation need to pay attention to a few matters, hoping to be able to help you.
1. The foundation should be horizontal and not skewed, and the center line of the cooling tower is perpendicular to the horizontal plane, otherwise it will affect the motor operation.
2. Because the tower body cannot accept the water pipe component, it is necessary to set up another pillar when setting up the water pipe. The water outlet pipe above 10mm of the cooling tower should be connected with an anti-vibration hose (high-pressure hose). When setting up the chassis, the installation personnel should step on the reinforcing ribs of the chassis to prevent damage to the chassis. When setting up the chassis shell chassis and other fiber parts, screws should be put on first, and then tightened in sequence to prevent deformation of the chassis deformation, and after the joint and the surrounding dry, can be in the joint laying fiber wool and altered resin, to prevent the tower leakage.
3. The electric fan of the cooling tower shall rotate clockwise with the wind direction upward (or outward). The gap between the blade tip of the fan and the inner wall of the tower shall be uniform. Check whether the viewpoint of the blade device is the same, whether the debugging work is balanced, and whether the power supply is the same as the rated power. The motor shall be wired according to the marked wiring direction. The junction box shall be sealed after wiring. The motor circuit shall be provided with phase missing operation maintenance and overload operation maintenance, to ensure the reliable operation of the motor.
