The air coolers in our factory do not provide good cooling performance; can the temperature be reduced by increasing the rotation speed? Motor voltage: 380V, Power: 30KW, Frequency: 50HZ, Speed: 984RPM. Is there any better solution?
What does wind-cooled air look like? How is the on-site setup?
Has it been properly flushed? The air cooler needs to be flushed at this time.
Could you please explain in detail how to make this adjustment specifically?
It was just washed, and the heat dissipation is still poor
The heat exchange efficiency is poor for several reasons. First, insufficient margin may have been included in the initial design of the heat exchanger; now that the ambient temperature has changed, the power available is not enough. Second, check whether there is scaling inside the heat exchanger tubes, as this can impede heat transfer and requires cleaning. Third, verify whether the blade angles of the fan are still the same as before; if the air flow has decreased, it’s necessary to examine the entire process – you can send me a private message
If it is confirmed that there is nothing wrong with the fan, adjusting its speed is also an option; at the same time, the opening angle of the blades can be adjusted. Depending on the weather, in conditions like intense sunlight when the ambient temperature is high, the blades should be set to a smaller opening angle, or even closed entirely.
If the speed is increased further, will you need to replace the motor and the air-cooled bearings? The cooling effect has been poor since the start of operation
Was it rinsed with fire extinguishing water by oneself, or was it cleaned professionally?
It can be considered from a process perspective···
