Description

The FN series square counterflow fiberglass cooling tower is an energy-saving new product. This product applies the patent of “energy-saving fiberglass cooling tower”, especially the cooling

tower fan is equipped with a variable torque off-pole two-speed motor. When the temperature is low (such as at night), the motor runs at low speed and the cooling tower noise can be reduced by 3-5dB(A). In addition, the energy saving effect of using a twospeed motor is significant. After calculation, when multiple cooling towers are equipped with single-speed motors, although some of the motors can be stopped to save energy when the air wet-bulb humidity is low, it still consumes 40% more power (in years) than using two-speed motors. ). This product also applies the patent of “oblique trapezoidal wave filler sheets for square counterflow cooling towers”, and its thermal and resistance characteristics are better than other fillers.

Specification

Square counterflow cooling tower has three series, nine models, ninety products: product performance and selection.

1. Design parameters: industrial tower: air wet bulb temperature τ = 28 ℃, cooling tower temperature drop: 10 ~ 25 ℃. Civil tower: air wet bulb temperature τ = 28 ℃, cooling tower temperature drop: 5 ~ 8 ℃.
2. Choose the tower need to know the cooling water Q, into the tower water temperature t1, out of the tower water temperature t2, air wet bulb temperature τ.
3. The cooling tower materials can withstand -50 ℃ low temperature, but for the coldest average monthly temperature is less than -10 ℃ of the region should be specified when ordering in order to take anti-icing measures.
4. The turbidity of the circulating water is not greater than 50 mg / liter, short-term not greater than 100 mg / liter. Should not contain oil and mechanical impurities. Algae and water quality stabilization measures need to be taken when necessary.
5. The direction of the inlet and outlet pipes of the cooling tower can be rotated according to 90°, 180°, 270°.
6. Water distribution system is designed according to the nominal water flow, such as the actual amount of water and the nominal amount of water difference in +15% or more, the order should be specified in order to modify some of the data.
7. Cooling tower water temperature does not exceed 60 ℃, such as more than 60 ℃ should be specified when ordering.
8. Fan blade installation angle adjustable, but to keep the angle consistent. And the current of the motor does not exceed the rated current of the motor.
9. The fan can be short low-speed reversal to eliminate ice.
10. When using the cooling tower water pan as a pool must be installed separatel”automatic water supply pipe”, “rapid water supply pipe”, “drain pipe”, “overflow pipe “, when ordering must be put forward in particular, the cost of another.
11. Motor, fan are supporting the supply, need to be sent to the site of the factory staff installation or technical guidance.

Design Description

1. The data in the table is for a single tower, and the number of tower groups can be combined according to requirements.
2. The elevation of each foundation is the same, the allowable deviation is ±-2mm, and the allowable deviation of the center of each foundation is ±2mm.
3. The tower columns are welded in position to the pre-embedded steel plates of the foundation.
4. Please ask for detailed basic drawings separately.
