Specifications

1. Name: Stirling Engine Model Kit

2. Model: E23553

3. Color: Silver

4. Materials: Aluminum alloy+Stainless steel+Thickened glass

 

Features

-Engine principle is intuitive, educational toys. Exquisite workmanship made, good for gift presentation as well powerful, ready to run, good for physics teaching demonstration.

-Powered by only a small alcohol lamp, you can make it fast rotation and strong power.

-As the external combustion engine to avoid the traditional internal combustion engine of the explosion to do work, in order to achieve a high efficiency, low noise, low pollution and low operating costs.

-The biggest advantage of the external combustion engine output and efficiency from the influence of altitude, very suitable for high altitude areas.

 

Instructions

-The engine model on the horizontal position by hand toggle the flywheel to see if smooth, if there is a strong sense of raw astringent, check the connection rod is normal, whether the cylinder oil and dust, and if so, please use toilet paper to erase Not smooth. Toggle the flywheel feel pressure rebound within the cylinder body is a normal phenomenon, the cylinder is sealed.

-The packing bag of alcohol lamp cotton wear into the metal cap lamp.

-Please go to the pharmacy to buy 95% purity alcohol, anhydrous industrial alcohol better. Fill the alcohol lamp to less than two-thirds.

-Alcohol lamp to the alcohol lamp, at the premise of ensuring safety, ignite the alcohol lamp about 2 minutes after the flywheel, until the flywheel automatic operation so far, the whole process of heating, hands may not touch.

-Led lights can be directly into the generator output interface, if not inserted, the exchange can be positive and negative, led a long foot for the cathode.

 

Safe End Procedure

-After use, allow the engine to cool naturally.

-After the engine cools naturally, keep the engine out of the reach of small children.

-Children in adults under the care of the use of the engine, so as not to burn or break accidentally broken bar injury.

 

Note

-Do not touch the baked test tube and the connected metal.

-After long time lighting, the alcohol lamp can not be touched.

-Suitable for people ≥8 years old, and need to operate under the guardianship.

-When heating, do not touch the tube of alcohol lamp tube, combustion will produce moisture, if touched, may lead to tube cracking.

-Both ends of the connecting rod joint activities need to add regular oil lubrication, the piston can not refuel, otherwise it will not work the resistance.

Material:

1. The bottom plate is made of brushed aluminum alloy, which is exquisite and beautiful.

2. The bracket is finished with CNC finishing, firm and strong

3. The flywheel is made of aluminum alloy, which combines texture and beauty.

4. The connecting rod is cut by stainless steel laser

5. The heating cylinder is specially made thick glass material, long-term heating without pressure

 

Features:
The Stirling Engine Principle was invented in 1816 by a pastor Robert Stirling in London, so it was named Stirling engine. The Stirling engine is a unique heat engine because their theoretical efficiency is almost equal to the theoretical maximum efficiency, called the Carnot cycle efficiency. The Stirling engine is powered by the expansion of the gas and the contraction of the cold. This is an external combustion engine in which the fuel is continuously burned, the expanded air (helium ) acts as a medium to move the piston, and the expanded gas is cooled in the cold chamber, and such a cyclic process is repeatedly performed. Only a small alcohol lamp is needed to make it fly fast and powerful.
