What to do if the circulating water temperature is high?
Thread Content
The temperature of the circulating water in our plant remains high. All four fans are running, water is added frequently, the pressure at the pump outlet has increased, while the pressure of the return water has decreased. Part of the packing has also been replaced, but the water temperature is still high. Are there any other effective solutions?
It can only be said that the fan is too small; all other methods are only temporary fixes. It’s best to calculate the fan’s power again. Additionally, measures such as cleaning the fan blades, slightly raising the outlet temperature on the process side of the process water cooler, and increasing the amount of water supplied as well as the amount of water drained can also help
It’s not clear whether this problem is inherent or acquired; if it’s inherent, it relates to the design, while if it’s acquired, then it’s necessary to identify the source of heat, such as a leak in the cooler (air leaking into the water phase), deformation or collapse of the packing in the cooling tower, or detached nozzles……………
The device is too small! Reduce load! Pipe scaling is even harder to deal with!
Is the filler clogged? Is there any flow deviation? What is the operating condition of the circulation pump? What is the temperature difference between the water temperature at the outlet of the circulation pump and the return water temperature? Can the cooling system help reduce the load? Investigate the causes from various aspects.
Has it always been like this, or did it gradually become like this? An increase in the pressure difference between the inlet and outlet water indicates increased pipeline resistance; there may be quite a bit of scaling, and the heat exchanger can be taken apart for inspection during maintenance
Are there any specific good measures? All four fans are running at full capacity, and the fan angles have also been adjusted
Hydrating is necessary almost every day; it can lower the temperature by one or two degrees, but this isn’t a long-term solution
During the maintenance in summer, it was found that the packing was broken and dirty, so part of it was replaced, but it stopped working again after just a few months
