Custom design , 3D printing, electrical repair.
I have been experimenting with printing a viable air pump to use to boost engines.
I will document my experiments here , as well as link my you tube videos.
I'm currently working on an aluminum housing for the vane type, I plan on using my printed prototype as a design to built a production level prototype
I have to do some modification to thee drawing, for machinability. I plan on sand casing a finned housing , and cast endplates.
This is the current state of the single stage side channel blower.
Powered by a 115vac induction motor that draws 0.8A ,and spins around 1400 rpm. The original gearing I attempted would have spun the blower just under 7000 rpm but this motor lacks the power to achieve this. I then lowered the gearing to around 3500rpm
The updated version ( seen assembled on YouTube) has completely open ports for ,easy flow.
heavy housing to improve rigidity.
offset vanes in the rotor ( limits direction of use) with vent holes for the pressure to force the vanes out improving efficiency at low rpm. Genorates3 lb of pressure at aproxamitly 4000 rpm
The centre drum if offset and the vanes slide out to meat the inside of the housing. this creates sealed pockets, witch expand and contract. the pocket expanding over the intake port draws air in, and contracting as it rotates by the exhaust port forces the air out.
improved design elements on the roots blower are , better seals( can be purchased or printed) thicker gears, and a stiffer housing .
I have also adjusted the clearance and radius of the lobes on the rotors for a little better fittment.
The updated rotors ,I went from 4 lobes back to 2 lobes. I also designed nylon seals for the rotors.
I have updated the seals on the shafts as well as gaskets and bolt circles on the housing and covers.
I attempted to make the gears from nylon, but in practice the D shaft drive on the shaft ended up distorting the whole and messed with the timing of the rotors.
My first attempt at a roots blower, it ended up moving a decent amount of air , but wouldn't hold any pressure while deadheaded.
