Windmills (windmills wind) are a type of energy that does not require fuel and uses wind as mechanical energy. The first wind turbines were also called windmills. Modern wind turbines mainly refer to wind turbines used for electricity generation and are also used to lift water for irrigation.

The old windmill developed from sails. It had 6 to 8 sail-shaped canopies, distributed around a vertical axis, when the wind blew it rotated around the axis like a rotating lantern. . Due to its low efficiency, this type of wind turbine has been gradually replaced by wooden canvas wind turbines with horizontal rotating shafts and other wind turbines, such as "vertical wind turbines", "automatic rotor wind turbines".omatic”, etc.

Ancient Chinese windmills have obvious characteristics. In addition to the horizontal axis, the sails are sail type. The sail is not mounted radially from the wheel shaft, but is mounted on eight posts around the shaft frame. The sail is again biased, that is, the canvas is narrower on one side of the mast and wider on the other side, and is tensioned with ropes. As shown in Figure 1, when the wind acts on A, the sail is downwind, the sail is perpendicular to the wind direction (maximum force) and is taut by the rope when turned to position C, the sail is blown outwards; , and the sail surface is parallel to the wind direction; to E Then return to the upwind position.

Thanks to the tension of the rope and the slope of the sail, it can take advantage of the wind or headwinds, just like when sailing a ship. This installation method allowsmakes the sail swing freely with the wind without generating any particular resistance. The effective range of peripheral rotation wind force of the sail exceeds 180 degrees. If you are in G position and start to turn downwind, the sail can still use some wind power to operate in a small amount. This feature of a sail-type windmill is unique in China.

The video tutorial for making a steam boiler is as follows:

Open the drain valves on the main steam pipe and the main air pipe to discharge the condensed water. When the gas pressure of the natural gas steam boiler is 0.05-0.1 MPa lower than the gas pressure of the operating system, gas melting can start.

Slowly open the bypass valve of the main gas valve of the steam boiler at gnatural az to warm the pipe. When the sound of airflow is no longer heard, gradually open the main gas valve (open fully then). reverse half a turn). Then close the bypass valve and the steam traps on the main steam pipe and the main air pipe. Air pressure and water level should remain normal during air melting.

If there is a water hammer in the pipe, it must be drained and then filled with air. After the gases merge, open the main economizer baffle and close the bypass baffle. When there is no bypass line, turn off the return water line to allow the economizer to operate normally.

Notes:

p>

1. Before using a steam boiler, be sure to check whether the internal parts of the steam boiler, tsuch as steam pipes, pressure gauges, water level gauges, etc., are in a safe and intact condition. the water in the steam boiler must be softFor chemical treatment, the water must remain clean and must not contain grease.

2. For the steam boiler safety valve, be careful not to adjust it arbitrarily, just make sure it is at the best level. This does not need to be adjusted at any time. The exterior of the product must be kept clean at all times.

3. When using a steam boiler to increase pressure, be sure to check the gas valve for sensitivity and check the water level. Remember to keep the water level at two-thirds of the water level meter. Position is very important. It should not be too high or too low, otherwise there would be a risk of explosion.

4. If you notice that the steam boiler furnace is burning red, you shouldimmediately stop using the steam boiler, because if you continue to use the steam boiler in this case, it will easily damage the steam boiler product.

Fountain refers to spring water ejected from the ground to the ground and specifically refers to artificial water spraying equipment. A fountain is a combination of a specific shape that sprays water or other liquid through a nozzle under a certain pressure. Water pressure is usually provided by a water pump. Generally speaking, fountain landscapes can be divided into two categories. One is carried out according to local conditions, based on the topographic structure of the site, imitating natural water landscapes, and the other is artificial landscaping that relies entirely on fountain equipment.

A fountain is a water feature constructed from artificial plastic pools or springss natural water that projects beautiful water for people to watch. The fountain is an important landscape. It is a kind of waterscape art that embodies the combination of movement and calmness, forming a bright and lively atmosphere, giving people beautiful enjoyment.
