Stirling Engine with Helicopter Design Vacuum Engine Model Science Toy Decor Collection

The Stirling engine model is with helicopter design, the horizontal single-cylinder vacuum engine structure, Rotor-disturbed air-cooled cooling, make the Stirling engine model is novel, exquisite and beautiful.

Features:
1, The helicopter design Stirling engine's body is made of aluminum alloy and stainless steel, the cylinder is made of tin bronze, the surface is gold and silver, cool and charming, achieving a combination of texture and beauty.
2, The operation steps are simple: first assemble the rotor, the rotor has two blades, screw the rotor into the spindle to tighten the top screw, and then assemble the base foot cup. Then add 95% alcohol, and add the amount to the 3/2 cover of the alcohol lamp cover lamp cover. Turn the rotor clockwise to start.Engine speed range 300-1000 rpm, continuous running time is 20 minutes.
3, The machine adopts disassembly-free maintenance.The syringe is filled with alcohol from the smoldering port and the flywheel is cleaned and the cylinder is poured out.The cleaning can be done twice. When the oil is lubricated, fill 0.5 ml from the sputum port with a syringe, fill it once before starting, and fill it once for 20 minutes. Compared to other dry lubrication, piston cylinders are lubricated to minimize wear and extend service life.
4, The Stirling engine is powered by thermal expansion of the gas and compression by cold. By personally operating, you can understand the operating principle of the vacuum Stirling engine more intuitively by observing the entire engine running process, and deepen your interest in physics learning. Besides, its superior quality and exquisite appearance also make it have a high collection value, which can be used as a high-grade decoration. 

Tips:
1, After using it, please let the engine natural cool. Don't touch the alchohol burner, burned tube or the metal to avoid scald.
2, Rods at both ends of the activities of joint parts need to regularly add oil lubrication.
3, Please be careful for the shape part when the engine works!
4, The Stirling engine model is suit for people over 14 years old. Operate under adults' supervision.
