Shop / sunnytech low temperature stirling engine motor steam heat
A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, such that there is a net conversion of heat energy to mechanical work. This makes it an excellent educational model for students and teachers, as it can help them better understand the working principle of such engines.
One of the key features of this Stirling engine is that it can run freely on the top of a cup of hot water, without the need to fire an alcohol lamp, making it safer for children. The start temperature difference between the product's bottom contact and the surrounding environment should be greater than 25°C.
Gently flipping the wheel is all that's required to set the engine in motion, and it will then run on its own. The exquisite frosted plunger can help to avoid steam leakage and reduce abrasion. If the friction between the flywheel and support is too high, a little graphite dry lubricant can be used to quiet it down nicely. However, it's important to avoid using oil, as this can lead to oil-dirt buildup.
The Stirling engine model, designated as LL-001, is available in two color options: gold or purple. It is made from a combination of stainless steel, spray-painted carbon steel, and glass. The engine can reach a maximum speed of 180 rpm.
In terms of specifications, the item size is 12.2 * 10.2 * 10.2 cm (4.8 * 4 * 4 inches), and the item weight is 250 g (8.8 oz). The package weight is 340 g (12 oz), and the package size is 17.7 * 12.3 * 9.7 cm (7.0 * 4.8 * 3.8 inches). The package includes the Stirling engine model and a user manual in English.
It's important to note that children under 12 years of age should be accompanied by an adult when playing with this product.
The Stirling engine's ability to run freely on a cup of hot water, without the need for an alcohol lamp, makes it a safer and more accessible educational tool for students and teachers. By understanding the working principle of this engine, students can gain valuable insights into the conversion of heat energy to mechanical work, which is a fundamental concept in thermodynamics.
