Description
- Stirling engine: Stirling engine is a type of thermal engine that works by circulating compressed and expanded air or other gases (working fluids) at different temperature levels, thereby converting thermal energy into mechanical work. An engine is like a Steam engine. All the heat from the engine comes in and out through the engine wall.
- Working principle Unlike the Steam engine, which uses liquid and gaseous water as working fluid, the Stirling engine has closed a fixed amount of permanent gaseous fluid, such as air or helium. Like all heat engines, the general cycle includes compressing cold gas, heating gas, expanding hot gas, and finally cooling the gas before repeating the cycle.
- Easy to install This beautiful low-temperature Stirling engine may be a great gift for your friends, family or yourself. Put the cryogenic Stirling engine model on a cup of hot water, slightly rotate the flywheel, and it can start by itself.
- Lubrication Lubricants can be applied with graphite or 2B pencils, and glass pistons are "air film lubricated" without the need to add any lubricant, just keep them clean
- Attention It is strictly prohibited to use lubricating oil. The oil will react with factors such as dust in the air to produce oil stains, which cause significant friction and is difficult to clean. On the contrary, the model cannot rotate.
