Centrifugal fan, which is a kind of fan, for us, it is also the object that needs to be focused on, because it is one of the website products and keywords, so it will be required. And, this is for us, is also beneficial and harmless, can come to increase their professional knowledge, so, why not!
1. If you want to adjust the air volume of the centrifugal fan, then how can you do it?
If you want to adjust the air volume of the centrifugal fan, then, there can be some measures, such as installing a frequency converter, to achieve this purpose. In addition, you can also use the adjustable damper, which can also have the same effect. As for, which one should be chosen, it is to see the actual situation and use requirements, by them to decide.
2. Are the centrifugal fan 4-72-8# -18.5KW /4 and 4-72-8#30Kw/2 the same in air volume?
Centrifugal fan 4-72-8# -18.5kW /4 and 4-72-8#30Kw/2, these are two different specifications and models of fans, as can be seen from their representation. Therefore, they are two different fans, in the air volume, is certainly not the same, the former is 15826-29344m3 /h, the latter is 19646-32380m3 /h.
3. Is there a corresponding description of the limit speed of the centrifugal fan?
For the limit speed of the centrifugal fan, there is a corresponding explanation. Generally speaking, there will be a report after the selection, which includes the content of the theoretical limit speed. Moreover, if the fan air volume, air pressure and other parameters are not the same, then the actual use effect of the fan is not the same. However, if the parts are standard, then, generally not much change.
