Except for oscillating gas, there are no moving parts in the system. According to different sound field characteristics, thermoacoustic engines are mainly divided into three types: standing wave type, traveling wave type, and standing wave traveling wave hybrid type. *** FEATURES *** * The thermoacoustic engine model is also exquisite and beautiful, but its unique inspiration makes it different from other gift models. * The thermoacoustic engine is a new type of thermodynamic machinery that uses thermoacoustic self-excited oscillation to work. It has the outstanding advantages of simple structure and high reliability. Thermoacoustic is an edge technology involving both acoustics and thermodynamics. * We made the thermoacoustic engine into a compact model, and gave it an exquisite and fashionable appearance, making it a unique gift or collectible. *** SPECIFICATIONS *** Size: 9.8″ x 3.5″ x 3.5″ ( 250*90*90 MM ) Weight: about 9.5 oz (270 g) *** PACKAGE INCLUDE *** 1PC of engine model *** ATTENTION *** A. Start-up steps *** 1. Put the model on the horizontal surface; add some alcohol into the alcohol lamp 2. Light the alcohol lamp; turn the flywheel by hand until the flywheel can automatically rotate 3. In the process of start, move the alcohol lamp to let the model run to the best 4. The height of the alcohol lamp wick should be no less than 15 mm, and you can adjust the wick height to achieve the best operation. B. Matters needing attention 1. When heating, do not touch with your hands cylinder and heating portion. 2. Avoid other liquid substances come into contact with cylinders in case of cylinder rustiness; extinguish alcohol lamp after finishing the demonstration. C. Maintenance plans (if the model is not running very well) 1. Check if there is enough alcohol in the alcohol lamp. 2. Check if the small and big wheel jackscrews loose or not. 3. Too high temperature in the air cylinder because of the continuous heating for a period of time will affect the performance of the product. 4. Check the valve position: the highest position of the flapper valve (2) is to cover one fourth of the valve port. 5. Check if the angle is correct or not: when the piston (7) lies in the innermost of the air cylinder, the small jackscrew (3) hole should be just facing the positioning port (6). If the position is wrong, please loosen the jackscrew; then tightly fix the jackscrew in the correct position.
