ENJOMOR Mini α Structure Hot-Air Stirling Engine Electric Generator 4000rpm - Gift Collection

ENJOMOR Mini α Structure Hot-Air Stirling Engine Electric Generator 4000rpm Science Educational Mechanical Toy And Gift

Features:

.The stirling engine features strong power and high speed designed with T rocker and crank with an α Structure.
.The moving parts of the engine is all engineered with rolling bearings for low friction coefficient.
.The cylinder is made of brass and the piston precision grinded SUJ-2 alloy steel. This two parts of wearproof engine are fit tightly with each other with high toughness.
.The whole connection is fixed with bolts and all connecting parts are sealed with copper washers for astounding performance and high temperatures resistance.
.Built with high density aluminum alloy heat sink for higher heat exchange rate and double-layer spring for shock absorption, the engine is capable of smooth running.
.Made of full metal, the engine model is small in size, compact in structure and reliable in performance.
.Assembled with over 150 small parts including 12 rolling bearings, 30 stainless steel bolts, etc.
.To create a all-metal exquisite model with industrial processing level, the unfading surface is treated by sand blasting oxid after the CNC processing with 6061 aluminum alloy in appearance.

Instructions For Production And Maintenance:
1. Before using, stir the flywheel to check the rotation smoothness, excessive resistance and mud jam in the cylinder. If necessary, remove the cylinder assembly to wipe the piston and cylinder with alcohol and apply graphite lubricant to the piston surface.
2. Pour 95% alcohol into alcohol lamp (less than 2/3 of all capacity), then ignite the alcohol lamp and place it under the heating cylinder for 40s (as closed as possible the heating zone), and finally stir the flywheel to rotate at high speed.

Notes:
1. Never touch the heating cylinder, heat sink and related high temperature parts during operation owe to the heat source will heat the body in high temperature, otherwise it will lead to thermal burns.
2. Only use genegral alcohol lamp. Never use wind-proof lighter and other high temperature heaters with Class E fire (over 500℃), or the piston cylinder will operate at high temperature and high speed to cause damage.
3. Do not apply any lubricants on the piston cylinder, otherwise it will lead to too much resistance to work.
4. Due to the threshold pressure, it is recommended for beginners to start with the engine base by hand for the first time for easier control.
