Difference in working principles between centrifugal air compressors and centrifugal water pumps
Thread Content
I’ve been puzzled by one question: since they are both centrifugal systems with impellers, why does an impeller in a centrifugal water pump fail when there is air present, while the impeller in a centrifugal compressor is able to throw that air out? Seeking advice! It’s best to be simple and easy to understand ； Everyone knows that there are different impeller structures, such as open-type and closed-type, etc
The principle is the same; both make use of the principle of centrifugal force! However, due to differences in medium density, compression ratio, viscosity, etc., the blade angle curves of the two types of impellers are different! Centrifugal pumps can also expel air, but the efficiency is extremely low!
If it’s a load with a bucket of water on one end and the other end…
I don’t quite understand; there’s a huge difference in the export pressures between the two
