Stirling engine is a heat engine in which the working fluid (gas or liquid) moves in a closed volume, in fact a kind of external combustion engine.This mechanism is based on the principle of periodic heating and cooling of the working fluid.Removing the energy comes from the emerging volume of the working fluid.The Stirling engine works not only on the energy of the burning fuel, but also from any source of heat energy.Patented this mechanism Scotsman Robert Stirling in 1816.
described mechanism, despite the low efficiency, has a number of benefits in the first place is the simplicity and unpretentiousness.Because of this, many amateur designers to attempt to assemble the Stirling engine by hand.Some succeed and some do not.
In this article we will discuss how to make the Stirling engine with their hands out of scrap materials.We need the following tools and blanks: a tin (can be from the sprats), sheet tin, paper clips, foam, rubber, bag clippers, copper wire, pliers, scissors, soldering iron, sandpaper.
now proceed to the assembly.Here are detailed instructions for how to make the Stirling engine by hand.First, you need to wash the jar, sanded the edges.Cut a sheet of tin circle so that he lay down on the inside edges of the banks.Determine the center (for this use a caliper or ruler), make a hole with scissors.Next, take the copper wire and paper clip, straighten a paper clip at the end of the ring do.We wound on the clip wire - four solid round.Next, a soldering iron spiral proludim received a small amount of solder.Then the spiral must be carefully soldered to the hole in the lid so that the lid stock turned perpendicular.The clip should move freely.
After that needs to be done in the cover communicating hole.Foam do propellant.Its diameter should be slightly smaller than the diameter of the cans, but this should not be a large gap.The height of the propellant - a little more than half of the banks.Cut padded in the middle a hole for the sleeve, the latter can be made of rubber or cork.We put in the resulting sleeve to seal the stem and all.Blowing the lid should be placed in parallel, it is an important condition.It remains to close the jar and solder the edges.The joints must be sealed.Now we proceed to the manufacture of the working cylinder.For this cut out from sheet metal strip 60 mm long and 25 mm wide is folded edge pliers 2mm.We form a sleeve, then solder the edge, then must be soldered to the sleeve cover (above the opening).
can now proceed to the manufacture of the membrane.To do this, cut off a piece of the film from the package, a little pressed his finger inside, rubber presses edge.Next, check the correct assembly.Heat the bottom of the banks in the fire, pull on the pushrod.As a result, the membrane must bend outward and release the rod if, under its own weight propellent should fall, respectively, the membrane returns to its place.In that case, if the displacer is made incorrectly or soldered cans is not sealed, the stock will not be back in place.Then do the crankshaft and the rack (dressing cranks should reach 90 degrees).Height cranks should be 7 mm and 5 mm propellants.The length of the rods to determine the position of the crankshaft.The end of the crank is inserted into the tube.So we looked at how to assemble the Stirling engine by hand.
Such a mechanism would work on an ordinary candle.When attached to a flywheel magnets and the coil to take aquarium compressor, such device can replace a simple electric motor.His hands, as you see, to make such a device is not difficult.It would be the desire.
