I am trying to build a prototype which needs to have a compressor as one of the parts. I want to mount a compressor to a bicycle wheel (the wheel being the prime mover) So I need the compressor to be either a vane, screw or gear pump/compressor.
It will need to be light and cheap structurally (hopefully plastic).
I am wondering if I can use an existing pump like an auto fuel pump or something like that to compress air. It would seem as long as the pump is positive displacement I would be able to compress air with it. What is your thought on this?
Bill stumbles with a reply…
Hi Rodney….whew, very interesting issue. Glad you took the time to write in.
The issue, as I see it, and one that I don’t see the answer to in your question is, how much air at what pressure do you need to generate with the bicycle driven compressor?
Can you use a positive displacement pump as a compressor? Sure.
Can you drive the shaft of that pump from any rotary drive source (including a bicycle wheel)? Sure.
I don’t have any concrete suggestions except that you need to narrow down flow and pressure requirements to help determine whatever style of compressor you ultimately decide on.
Anyone out there have any thoughts for Rodney?
