Description
Aerodynamics is rich in knowledge of physics and single-cylinder internal combustion engines.
The engine principle is intuitive, educational toys, teaching experimental equipment can
Effectively cultivate children's interest in learning, and can also be used in the classroom
Teaching, more intuitive and easy to understand.
Specification
Name: Double-cylinder engine model
Material: aluminum alloy, glass
Color: silver gold
Size: 160 x 87 x 110mm
Instructions:
The engine model is manually switched with the flywheel in the horizontal position to see if it is smooth. If there is a strong feeling of raw stringier, check whether the connecting rod is normal, whether there is cylinder oil and dust. If so, please use toilet paper to clear Not smooth.Switch the flywheel and feel the pressure rebound inside the cylinder body. This is a normal phenomenon, the cylinder is sealed.
The cotton alcohol lamp packing bag wears into the lamp with metal cap.
Please go to the pharmacy to buy 95% purity alcohol, anhydrous industrial alcohol better.Fill the alcohol lamp to less than two-thirds.
To the alcohol lamp to the alcohol lamp, to ensure safety, ignite the alcohol lamp about 2 minutes after the flywheel, until the flywheel runs automatically so far, during the whole heating process, hands may not touch.
LED lights can be directly inserted into the generator output interface, if not plugged in, the exchange can be positive and negative, and a long foot for the cathode.
Note:
This motor is perfect for children over 12 years old.
There will be the operation of the steam, if the steam is too strong, the motor will stop working.
The inside and outside of the needle are often put aside to reduce friction
Do not turn the nut too tightly, otherwise the glass will be broken if the piston is cracked.
can be glued with glue.
The alcohol lamp wick does not touch the glass, the ring is not too tight
Pulling the piston connecting rod can not force the front end, because the front end is easy to break
