Product Description

Steam engine model

Product Introduction
This steam engine model belongs to the double driving steam engine. The steam is controlled by the reversing valve, and the piston can be alternately driven by the steam from both ends of the cylinder. Its working principle is highly representative. When the air source supplies enough simulated steam to it, the shock effect and visual impact caused by its high-speed operation can be observed. During low speed operation or manual slow swing, carefully observe the action relationship between the reversing valve and the piston, and it is not difficult to understand its working principle.

Some parts of the instrument adopt transparent design, which is convenient to observe the working details of various parts of the instrument from all directions without dead angle.

The instrument has two modes of pneumatic operation and manual operation for selection, and is equipped with a speed regulating mechanism to adjust the operating speed during pneumatic operation.

Product Specification

Product name	Steam engine model
Material	Plastic
Size	395x140x230mm

The instrument is composed of cylinder, piston, steam chamber, steam flow reversing valve, crank connecting rod mechanism, flywheel, support and base plate. In order to observe the working process of the piston and steam flow reversing valve in operation, the cylinder and steam chamber are made of transparent plastic. A steam passage is designed above the cylinder to connect with the steam chamber; The steam pressure regulating mechanism is designed on one side of the steam chamber to regulate the running speed of the machine. The flywheel is made of cast iron, and the piston, reversing valve, crank connecting rod mechanism, bracket, etc. are made of plastic.

Operating principle
The steam enters the steam chamber and is sent to one end of the cylinder through the steam flow reversing valve to drive the piston. Under the action of the crank connecting rod, the flywheel rotates and stores energy. When the piston moves to the pole, it reacts on the crank connecting rod under the inertia of the flywheel, making the piston rush over the pole and start to move in the opposite direction. At the same time, the steam flow reversing valve reverses, and the steam enters from the other end of the cylinder. The original exhaust passage becomes the steam inlet passage, and the original steam inlet passage becomes the exhaust passage, accelerating the reversing operation of the piston. Under the action of the crank connecting rod, the flywheel rotates and stores kinetic energy. When the piston moves to another pole, the inertia of the flywheel makes the piston move back, and the steam flow reversing valve reverses the steam flow of the two steam passages again. In this cycle, the piston continuously moves back and forth, pushing the crank connecting rod to work.

Instructions
This instrument is required to be used together with 21056 small air source. The air flow generated by small air source is used to simulate water steam and drive the steam engine to run.

Use inner diameter Φ The soft rubber tube of 29 connects the air outlet of the small air source with the steam inlet of the steam engine. Move the flywheel so that point A in the figure rises to the highest point. Turn on the power switch of the small air source, and the steam engine model can run. The running speed of the machine can be changed by adjusting the speed regulating knob outside the steam chamber.

If manual operation is required, screw the accompanying handle into the screw hole from the outside of the flywheel, rotate the handle, and observe the running state of the machine.

Product feature and application
The steam engine was the greatest invention during the first industrial revolution. Its extensive application has solved the power problem in industrial development and ended the long-standing dependence of human beings on animal power, wind power and water power. So as to gradually form socialized mass production. In the process of modern civilization of human society, its appearance has epoch-making significance. It has laid a solid theoretical foundation and provided rich practical experience for the later emergence of the internal combustion engine. Its simple and effective mechanical control principle is still widely used today.

Maintenance and precautions
1. Regularly drop a proper amount of silicon lubricating oil onto the rotating shaft and friction surfaces of the machine to reduce the noise caused by friction.
2. The instrument shall avoid collision and falling. When not in use, it shall be covered with a dust cover and placed in a cool and dry place.
3. If the fixing screws are loose, please tighten them in time.
4. It is not suitable to use organic solvent or hard objects to clean the stains on the surface of the instrument. If necessary, a soft cloth dipped in soapy water can be used to wipe.
5. Special attention: Do not touch the flywheel when the instrument is running to avoid safety accidents.
