Seeking help in selecting circulating fan equipment
Thread Content
I’ve encountered a working condition for which I can’t think of a suitable device; please help me figure this out. Process requirements: Pressurize the circulating air, with a flow rate of 50 Nm3/min and a pressure increase of 30 KPa; it seems that a Roots blower would be suitable. There is another requirement: the pressure throughout the entire circulation system must be 1 MPa; in other words, the inlet of the fan must be able to withstand a pressure of 1 MPa. Rotary vane fans generally cannot handle such pressures. This is contradictory: centrifugal fans can withstand pressure, but they cannot increase pressure to such a high level. . . . Could anyone recommend some suitable products?
It is recommended to include a flowchart, as it makes things clearer when explained with visuals. Both Roots blowers and turbine blowers can achieve such high pressures. As for the flow rate, it’s best to refer to the diagrams, which indicate the required process parameters. For reference.
There is only one core issue: the Roots blower can provide a pressure increase of 30 KPa, but its structure cannot withstand a gas pressure of 1 MPa. Wo9 is looking for a moving device that can withstand this pressure.
Screw compressors and reciprocating piston compressors work quite well
Centrifugal fans that can achieve this parameter – I’m not sure about other manufacturers, but mine can. Get in touch with me; I’ll send it to you via WeChat
A centrifugal fan? No way – can a centrifugal fan really increase pressure by 30 KPa? Which brand?
Imported centrifugal fans can be used; you can contact me via private message
A single unit can increase the pressure to over 40 kilopascals. Most of the fans used in our glass industry can handle pressures exceeding 30 kilopascals. If you listen to domestic manufacturers, there are probably few that can achieve a pressure of 20 kilopascals; most imported brands are capable of handling such pressures, and a few domestic models can also do so, but there are very few manufacturers that produce these models
And there’s something special about this one as well; I’ll tell you in private
Hehe, in terms of pressure, oxygen centrifugal compressors can reach 3.0 Mpa.
A multi-stage centrifugal fan will do.
