Although different types of closed cooling towers have different ways of wind, they also have some disadvantages. If these problems cannot be overcome, it will be difficult to break through the use of closed cooling towers. In the traditional design, the closed cooling tower always enters air from the lower or upper part of the tower. In this way, the shortcomings of small circulation area and large flow resistance not only affect the heat transfer effect, but also increase the utilization rate of the material. From the current market situation, this is very unfavorable.
If you want to overcome the above shortcomings, you must start from the closed cooling tower intake mode. You may want to try a new design, namely the form of air flow from the central part and up and down, which will greatly increase the circulation area, increase the air volume and increase the air volume. The cooling effect has a significant effect. At the same time, the new design can also avoid the shortcomings of hot and humid air recirculation caused by the upper air intake, thereby reducing production costs and improving product competitiveness.
In addition to changing the air intake mode of the closed cooling tower, ensuring the maximum value of each component is the basis for the cooling tower fan to perform its function. If the fan cannot be used for some parts, its function cannot be guaranteed. Especially the integrity of wind turbine components is the key. Before using the fan, check the application of each component. Make the operation of the fan as best as possible.
In order to make full use of the various components of the closed cooling tower fan, it is necessary to conduct certain tests on it. Visual observation is the method most users use, and it is also the most common method. This method is of course simple, but does not fully grasp the situation of the impeller.
Apply phosphor to the blade and wipe it off. Move the rotor or impeller to the dark room for observation. If there are cracks, the phosphor cannot be erased and will glow. This method is relatively simple. The cooling tower fan rotor or impeller is connected by magnetic particle testing, and the magnetic field of the impeller or rotor is generated by direct current. The top of each blade becomes a magnetic pole and then coated with iron powder. If there is a crack on the blade, two different polarities will appear at the crack gap, thereby absorbing iron powder. In this way, the position of the damaged blade can be detected.
