Centrifugal compressors used in series
Thread Content
You guys have a question: For the transformation of a centrifugal compressor, if I want to add a section, can I use a booster in series? Are there any disadvantages to doing this? For example, if the operation is difficult and it is easy to hold back the pressure, please give me some advice.
I have never seen your kind of modification. It is theoretically feasible. The flow rate remains unchanged and the pressure increases. So what about the speed of the supercharger? Is it higher than your current lowest level? How to achieve it? Economically, I am afraid it will be inefficient.
The flow rate remains unchanged and the pressure increases, so what about the speed of the supercharger? Is it higher than your current lowest level? How to achieve it? Economically speaking, I am afraid of low efficiency ------- the problem of growth rate can be easily solved by adding a growth rate box. However, reasonable speed, reasonable flow and other parameters as well as reliable design of the compressor require correct calculation by the supplier. As for series pressurization, the theory is certainly correct. In fact, multi-stage centrifuges have impellers connected in series.
Theoretically it is feasible, but there are many issues to consider in actual implementation. As mentioned above, it needs to be calculated by the compressor manufacturer. It is equivalent to building a new centrifugal supercharger, which is probably very expensive.
