Product features:
1. Watt used scientific theory, in 1765, invented a steam engine equipped with a condenser separate from the cylinder wall, from 1765 to 1790, he carried out a series of inventions, such as separation of the condenser, the cylinder outside the adiabatic layer, lubrication of the piston with oil, planetary gears, parallel motion linkage mechanism, centrifugal speed governor, throttle, manometer, etc., so that the steam engine's efficiency increased to the original Newcomen machine more than three times, and finally invented the industrial steam engine.
2.K007 is a one-way piston vertical steam engine, the machine is equipped with a set of vertical boiler, through the copper conduit will be introduced into the host steam, steam through the gas exchange valve into the cylinder, push the piston to do work, the piston crankshaft and the gas exchange valve crankshaft gear linkage, to control the intake and exhaust process.
3. Cylinder bore 14MM, piston stroke 12MM, cylinder liner and piston made of brass, as long as the steam machine is configured with a large enough gas source, the design of this large cylinder can provide considerable torque and power, if you only need to bring a micro-motor used to demonstrate the steam power generation, the machine's original boiler is sufficient to achieve. Larger cylinders require a larger air volume to drive the boiler, so the vertical boiler has been re-designed, the inner core is machined from 6061 aluminum alloy CNC lathe into a conical combustion chamber, which absorbs the heat generated by the combustion of the alcohol lamp over a larger area, and improves the combustion efficiency as much as possible in the limited boiler size to generate enough steam.
4. The boiler is equipped with a safety valve, when the pressure exceeds the set value of the safety valve, the safety valve automatically opens to release the pressure, and likewise a set of water level observers, so that the boiler can avoid running out of water during operation.
5. brass crankshaft, increase the semicircular dynamic balance design, φ38mm precision brass gear axial runout is less than 0.005MM, the flywheel and M20 series Stirling share a model with a diameter of 78MM, large flywheel to increase the inertia of the operation, so that the operation of a smoother.
6. Stainless steel connecting rods are equipped with F684 precision bearings, while gears and crankshafts are equipped with 4 sets of F696 high-precision bearings. The smoothness and quietness of the machine operation, and even the service life of the whole machine, can not be separated from more bearings.
