What is a Siphon?

The siphon is an elbow used to make the liquid siphon. It is composed of a siphon hose and a ball-shaped airbag. It has an inverted U-shape and a long end. The tube must be filled with liquid before use.

The siphon phenomenon is caused by the difference between the gravitational force and the potential energy of the liquid molecules, that is, the water column pressure difference is used to make the water rise and then flow to a low place. Because the water surface of the nozzle is subjected to different atmospheric pressures, the water will flow from the side with the higher pressure to the side with the lower pressure until the atmospheric pressure on both sides is equal. The water surface in the container becomes the same height, and the water will stop flowing. The water in the container will be pumped out soon.

The siphon is an ancient invention of human beings. As early as 1 BC, a strange siphon was created.

In fact, the siphon effect is not entirely caused by atmospheric pressure, and it can also produce siphon in a vacuum. The force that causes a liquid to rise is the cohesion of molecules between the liquids. When the siphon phenomenon occurs, because the liquid flowing out of the tube is more than the liquid flowing into the tube, the gravity on both sides is unbalanced, so the liquid will continue to flow in one direction. As the liquid flows into the tube, the pressure decreases as it goes up. If the liquid rising tube is high, the pressure will be reduced to cause bubbles in the tube (consisting of air or other components of gas). The height of the siphon is determined by the generation of bubbles, because bubbles will break the liquid The force between the gas molecules at the end is reduced to 0, which destroys the siphon effect, so the tube must be filled with water. Under normal atmospheric pressure, the siphon works better than under vacuum, because the atmospheric pressure on the two sides of the nozzle increases the pressure inside the siphon.

World's largest siphon sets Guinness record

Xinhuanet, Fuzhou, September 17 (Linstein). The largest diameter siphon in the world, developed by China and awarded an invention patent by the State Patent Office, is like a giant dragon lying in the Huangshiyu Reservoir near the suburb of Hangzhou, Zhejiang Province. On the dam, a steady stream of automatic pumping water is drawn. A few days ago, Weng Youbin, the inventor of this technology and the general manager of Fengze Dayu Vacuum Water Transmission Technology Co., Ltd. in Quanzhou, Fujian Province, received a Guinness Record Certificate of the World's Largest Diameter Siphon from the London, UK.

According to reports, this siphon has a diameter of 1520 mm, a total length of 96 meters and a height of 8 meters. Before the record of this maximum diameter siphon was reached, the maximum diameter could not exceed 600 mm, the height was 6.5 meters, and the length of the tube was no more than 60 meters. This world record not only set the world number one for siphons, but its height of siphons also greatly broke through the theoretical conventions, opening up the market application space and development space of ultra-large siphons in fluids, which has great economic benefits.

According to reports, siphon is a gift from nature. It is the use of the pressure difference and potential energy between the atmospheric pressure and the vacuum to continuously provide inexhaustible energy support, so as to achieve the phenomenon of automatic pumping water. The use of siphons to transport fluids does not require any additional power. It is a new type of energy-saving and environmental protection technology with a wide range of applications, such as long-distance diversion, tap water distribution, hydropower generation, flood prevention and drought relief, flood irrigation, reservoir dredging, groundwater recharge, and submarine ore mining and suction.
