The story of Archimedes inventing the earliest pump in history

Archimedes screw pump is a kind of screw pump invented by ancient Greek mathematician and scientist Archimedes when he was in Egypt. This is the earliest water pump in history, and its principle is still used by modern screw pumps.

Archimedes in ancient Greece was the earliest inventor of the water pump. Archimedes was born in the ancient city of Syracuse in Greece in 287 BC. The ancient economy of Syracuse was unprecedentedly prosperous at that time, and the wind of scientific research was very strong. Many people here have a lot of research on philosophy, geometry, etc. They like to debate and use it as an opportunity to learn. Archimedes lived in this atmosphere since he was a child and developed a good habit of thinking and learning.

At that time, the city of Alexandria, at the mouth of the Nile River, was the political, economic, and cultural center of the eastern Mediterranean, where many top scientists gathered. The studious Archimedes also came to Alexandria, where he studied mathematics, astronomy and mechanics. On Sunday, Archimedes and his classmates took a wooden boat and drove slowly on the Nile River. The beautiful scenery on both sides of the bank made him dizzy. Suddenly, he saw a group of people carrying water in wooden buckets and asked: "They are doing it. Why do you want to carry water?" "The riverbed is low, and the farmland is high. Farmers have to carry water to water the land." A local student told him. Bucket." Archimedes felt sympathy for the peasants. The classmate said disapprovingly: "People have done this for generations to come. What can you do?"

After returning home, Archimedes’ eyes always flashed in front of the farmers as they struggled to carry water. "Can you let the water flow up high?" Archimedes began to think about this question. Gradually, in Archimedes An idea came up in De's mind: "Make a big spiral and put it in a cylinder. Then, after the spiral turns, can the water be brought to a high place along the spiral groove?"

Archimedes immediately drew a sketch based on this idea. He took the sketch to the carpenter and asked the master to help him make a tool for pumping water. "According to Archimedes's guidance, the carpenter Made a weird thing. Archimedes moved this thing to the river and put one end of it into the river water, then gently shake the handle. "Gurulu", I saw the river water while shaking the handle , Constantly pouring out from the top of the strange thing. Water, as expected, flowed to a high place.

The farmers who came to watch were fascinated by this magical thing. They praised Archimedes for doing a great deed for the farmers. Soon, this kind of spiral pump spread in the Nile River basin and even wider areas. People call this kind of water pump Archimedes screw pump. Until now, some modern factories still use this Archimedes screw pump to move fluid and powder.

The working principle of the Archimedes screw pump is that when the motor drives the pump shaft to rotate, the screw on the one hand rotates around its own axis, and on the other hand it rolls along the inner surface of the bushing, thus forming a sealed chamber of the pump. Each time the screw rotates, the liquid in the sealed cavity advances by a pitch. With the continuous rotation of the screw, the liquid spirally presses from one sealed cavity to another, and finally extrudes the pump body. The screw pump is a new type of liquid conveying machine, which has the advantages of simple structure, safe and reliable work, convenient use and maintenance, continuous and uniform liquid discharge, and stable pressure.

In addition to screw pumps, we now have many different pumps. According to the industry, it can be divided into: petroleum pumps, metallurgical pumps, chemical pumps, fishery pumps, mining pumps, electric pumps, water conservancy pumps, water treatment pumps, food pumps, brewing pumps, pharmaceutical pumps, beverage pumps, oil refining pumps, seasoning pumps , Paper pumps, textile pumps, printing and dyeing pumps, ceramic pumps, paint pumps, pesticide pumps, fertilizer pumps, sugar pumps, alcohol pumps, environmental protection pumps, salt pumps, beer pumps, starch pumps, water supply pumps, heating pumps, agricultural Pumps, garden pumps, aquarium pumps, boiler pumps, medical pumps, ship pumps, aviation pumps, automotive pumps, fire pumps, cement pumps, air conditioning pumps, nuclear power pumps, mechanical pumps, gas pumps, oil-gas mixed pumps.

Archimedes is a great ancient Greek philosopher, encyclopedic scientist, mathematician, physicist, mechanic, the founder of static mechanics and hydrostatics, and enjoys the reputation of "the father of mechanics", Archimedes Join Gauss and Newton as the world's three largest mathematicians. Archimedes once said: "Give me a fulcrum, and I can pry up the whole earth." He is a great man admired by the world!
