HELP! Beta stirling model issues

[Lewis GoodParticipant @lewisgood32882]

Hi all!

I'm new to the forum and was hoping that you could pherhaps help me out with an issue i'm having with my beta stirling engine.

I recently brought the Beoplans drawings from ebay and managed to build the engine, although i have had to make various alterations and improvements to get it to work mechanically.

I can run the engine with an airline powering the flywheel to check the mechanism works and it runs smoothly however, when i try to run it with heat at the hotcap it doesnot run.

If anyone could offer any help or advice it would be greatly appreciated, and if you need me to be more clear or explain myself more i can do

Thanks,

Lewis

Sorry for the delay Lewis, could you put up a photo, it might help a little if we can see what you have. I don't quite understand you say you can power the flywheel with an airline, do you mean that you turn it by using the flywheel like a turbine, are you turning it the right direction? Next thing to look at is friction, you don't need any more than the bare minimum. The power piston must be a sliding fit in the cylinder, but if the displacer rod hole is blocked, its slide under gravity should slow to a near stop. The gland for the displacer rod should seal, but be free of friction. Make sure the displacer, assuming it is a cylindrical metal one, has no leaks, does not touch the sides, and has the prescribed clearance.

See if you can come up with a photo, or drawing, best wishes, and welcome. Ian S C
