Nízkoteplotný tepelný motor Stirling

Functions: speed up to 180-200 RPM Initial temperature difference: 20 oC Color: Silver Bottom Gold Flywheel Material: steel and glass Size: 100X100X120mm Weight: 250 grams lubricate with a pencil If necessary, use only pencil powder to lubricate the Stirling engine. Oil must not be added for lubrication as the oil mixes with the dust in the air and becomes oil dirt, making the friction even greater. The rotating motor cannot turn freely. Package includes: 1 x Stirling engine   What is a Stirling Engine? A Stirling engine is a heat engine that works by cyclically compressing and expanding air or another gas, a working fluid, at various temperature levels, thereby net converting thermal energy into mechanical work. that all engine heat flows through the engine wall. How it's working? This is conventionally known as an external combustion engine as opposed to an internal combustion engine where heat is introduced by combustion of the fuel in the body of the working fluid. Unlike a steam engine's use of both liquid and gaseous water as a working fluid, the Stirling engine is surrounded by a constant amount of liquid gas such as air or helium. As with all heat engines, general cyclists rely on compressing the cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle. This good looking low temperature Stirling engine can be a great gift for friends, family or yourself. It's almost ready to go: just install the flywheel. After 30 seconds of installation, put it on a cup of hot water, then it will act like Forrest Gump. Note: different parts of the crankshaft and connecting rod can lubricate with pencils, never lubricate with oil, after producing the oil staining, the friction is very great and it is not easy to clean !!!!
