Product Description:
This is a α-type double-cylinder, double-piston Stirling engine, there is no separate gas cylinder, corresponding to a set of cylinders with the cooling side of the cylinder structure is identical to participate in the exchange of heat and cold together with the work done, because it is a set of two independent and the same structure of the cylinders, one side of the cylinder is responsible for the generation of heat, the other cylinder is responsible for the cooling, and at the same time both sets of cylinders are generating power.
Due to completely independent, two sets of cylinders have obvious temperature difference, in the heating side of the front temperature up to 600 degrees, the temperature of the cooling side of the cylinder temperature after 20 minutes of continuous operation can still maintain a temperature of about 50 degrees, which will produce more than 500 degrees of temperature difference, which is also sufficient and continuous power output source.
Both sides of this engine use 20MM power cylinders and 20MM stainless steel heating tubes, the heating cylinder side of the heating tube is significantly longer than the cooling side of the heating tube, in order to design a better compression ratio.
The two sets of cylinder connecting rods are not directly connected, but are connected through two sets of gear system, the gear ratio is designed to be 2:1, the crankshaft speed reaches 1000r/min, and the flywheel with a diameter of 78MM and a weight of 155 grams has a speed of 2000r/min, which is due to the strong inertia of the flywheel, thus making the machine run more stably.
In order to satisfy the smooth and quiet operation of the machine as much as possible, we use 14 precision bearings for the whole machine.
In order to improve the life of the cylinder and piston, we choose bearing steel GCR15 as the raw material for the cylinder liner and piston liner, CNC lathe processing and quenching treatment to increase the hardness to 58-62HRC, and then through the grinding process, the precision can be up to plus or minus 0.005MM or so, the piston in the cylinder to do the reciprocating motion at the same time you need to seal as much as possible within the cylinder gas, which is a key part of the embodiment of the Stirling This is the key part of Stirling's precision.
Large size flywheel, double cylinders, double pistons, double gears, brass connecting rods, crankshaft, double 10MM aluminum alloy bracket, both sets of cylinders are inlaid with 2.5MM cylinder liner, in order to meet the smooth and quiet running of the machine as much as possible, the number of bearings used in the whole machine as many as 30.
Product features:
1、Advanced α-type configuration: Our Stirling engine has advanced α-type double-cylinder and double-piston design, which makes it have excellent heat transfer efficiency. The hot and cold cylinders are designed to be separated and the two sets of cylinders are designed to be isolated with stainless steel heat insulators so as to experience the best performance.
2, double-cylinder double-piston design: vertical cylinder design, thanks to this vertical cylinder large area overall heat absorption effect, the whole machine will be designed to cool the cylinder volume is greater than the heating cylinder volume, which is more conducive to the high temperature of the air to be rapidly cooled, thus creating a greater temperature difference.
3, quiet and smooth operation: enjoy the benefits of quiet and smooth operation. The dual-piston system not only maximizes efficiency, but also minimizes vibration, providing a calm and stable user experience.
4.DURABLE CONSTRUCTION: Our Sterling engines are made of high quality materials and are manufactured with precision and durability in mind. This ensures longevity and resilience, making it a reliable investment for those looking for a long-lasting, efficient power solution.
5.MULTIFUNCTIONAL APPLICATIONS: From educational presentations to practical applications, the α-Type Twin Cylinder Twin Piston Stirling Engine is versatile. It can be used as an excellent educational tool, a charming desktop decoration, or even a small generator for a wide range of interests and needs.
