discussed in this article goes to the great conqueror or destroyer, and the person significantly contribute to the development of civilization.He is the ancient Greek scientist Archimedes.His ingenious invention - the Archimedes screw.
lived and worked great scholar in very remote times, the year of his birth - 287 BCThey made a lot of discoveries.Fundamentals of hydrostatics and the famous Archimedes, improvement in leverage, burton, worm gear finally Archimedes screw - all that we owe to the great Greek.It is enough to recall his saying, come down to us across the abyss separating the time: "Give me a fulcrum and I will move the world."
Who is the famous Archimedes screw?Spiral placed in the cylinder - that's what it is.When you rotate it captures the liquid and carries it along.The gaps between the edges of the spiral and cylinder walls allow the shaft to rotate freely.As a result, water is poured through the upper open end.Thus, by placing one end of the cylinder into the water and is located above the other at an angle and rotating the shaft, fluid is fed upwards.Could rotate the shaft itself as the spiral inside the cylinder, and the cylinder with the shaft.
apply such Archimedean spiral for rising of water in irrigation areas for mine dewatering, the holds of ships, lowlands and wetlands.The effectiveness of this device was higher than that of the then water lifting wheels.An important advantage was that raised similar fashion as a pure liquid and mix it with the ground suspension.
As mentioned initially Archimedes screw was used to lift water from the lowlands, from the river up at the irrigated fields.Through such a system, irrigated fields in Egypt, Greece and elsewhere.Subsequently, this technique began to pump water from mines.Inclined design just fit in mining drifts.Through the use of pumping water using spirals available proved many previously flooded areas of the mines.Among the Spanish miners, in the opinion of historians, this method of drying has been extremely popular.
With no less success the Dutch acted on a similar method of drainage.They fenced plot of sea dikes and then pumped the water out of it land.Thus, they have increased their territory, conquering the land from the sea.
as technology ideas associated with the Archimedes screw, finding new applications.Virtually no one in industry, which is not used to self-tapping screws.But they are based on the same principle.
In many other cases as well have used this solution.Worm gear - it created the prototype of the great scientist.Screw mechanism can also be considered development of the idea Syracusans.How was subsequently created screw presses, it is impossible to even imagine.For centuries, mankind has got oil and wine, using such devices.
screw - is also modified Archimedes screw.It is used in a variety of normal oblastyah- grinder motors to transport.To overcome the swampy places where you can not use wheels or tracks, using all-terrain vehicles with screw engines.
Auger used for creating wells on private land and wells in the industry.And the ships move through the propeller, which is part of the spiral of Archimedes.Underlying all this is the opening of the Greek genius.
This material was considered the invention of the Greek scientist from Syracuse - Archimedes screw, shown its practical application in the past and the use of modern technology.
