The steam lifted the lid and Watt was inspired. When he grew up, he invented the steam engine and became a famous inventor. that
Actually, that's just a legend. Watt invented the steam engine not because of his childhood inspiration, but because he absorbed predecessors and his achievements.
The result of personal efforts.
1736, Watt was born in greenock, a small town near Glasgow, where the British shipbuilding industry developed. His grandfather and uncle.
My uncle is a mechanic and my father is a shipbuilding worker. Due to family poverty, Watt hardly went to school, but under the influence of the family, from
I have learned a lot about mechanical manufacturing since I was a child, and I have cultivated my interest in manufacturing machinery. Watt entered Glasgow at the age of 18.
I studied handicrafts, and later went to London to study mechanical manufacturing. 1757, Watt went to Glasgow University as an experimenter.
Specializing in manufacturing and repairing teaching instruments. The university provides Watt with a good opportunity to study and practice. He studies tirelessly.
Xi is also proficient in German and Italian. He asks university professors as much as possible and sometimes discusses science and technology with them.
Surgical problems.
1763, a steam engine sent to a university outside was repaired by Watt. Details of watt and several others
Study it.
This steam engine was invented and manufactured by a Scottish blacksmith named Newkman, and it was the most advanced steam engine at that time.
Yes Before Newkman, many people were interested in steam as the power of production. 1688, France
Chinese physicist Denis Papan once made the first simple steam engine with cylinder and piston. However, Papan's
This invention is not actually applied to industrial production. Ten years later, the British toy Seville invented the steam pump, which mainly
Used for mine pumping. 1705, after long-term research, Newkman combined the advantages invented by Papan and Seville to create.
Air steam engine.
After careful study, Watt found that Newkman's steam engine had many defects, mainly high fuel consumption, clumsiness and application.
Its scope is limited and it can only be used for mine pumping and irrigation. Watt is determined to build a better steam engine than it.
A year later, Watt's own steam engine started to ignite. But after the water boiled, the steam engine stopped.
Steam came out of it, and the room was filled with fog. It turned out that the steam engine leaked steam, and Watt's first experiment failed.
"I will succeed!" Watt believes in his ability.
However, the university does not support him to be a steam engine. At that time, it cost thousands of pounds to build a steam engine, while watt was a year.
His salary is only 35 pounds, so he has to ask his friends for help. A friend named Buck runs an iron works and a coal works.
He provided funds and gave him a lot of help. When the experiment was about to succeed, Buck suddenly went bankrupt and Watt went out again.
There is no way out.
"Watt, I have good news for you." Just as Watt was at a loss in the laboratory, the kind-hearted Ba
Dick ran around trying to find supporters for Watt.
"What good news? Tell me quickly. " Watt got excited and felt that things were promising again.
"There is a steel manufacturer named matthew boulton in Birmingham, and he promised to provide you with funds."
"What are his conditions?"
"He will provide all the expenses for the trial production of the steam engine and maintain your life until the business is profitable. you want
Use two-thirds of the patent right of steam engine as compensation for him. "
"Ok, I agree!"
Watt soon arrived in Birmingham, where, after repeated practice, he finally made a condenser with separation in 1796.
Single acting steam engine. This kind of steam engine has obvious advantages over Newkman's steam engine, which can save 75% fuel.
Watt is not satisfied with what he has achieved. 1782, he successfully built the steam engine. 178
Four years later, Watt improved it by adding a device to automatically adjust the speed of the steam engine, making it suitable for various applications.
A mechanical movement. Since then, textile, mining, metallurgy, papermaking, ceramics and other industrial sectors have emerged one after another.
The steam engine is used as power.
1807, American Fuer put Watt's steam engine on board. Since then, the sailing era of the shipping industry has ended.
18 14 years, the Englishman Steven put Watt's steam engine on the train, and a new era of land transportation began.
65438+ In 1930s and 1940s, steam engines were widely used in Europe and North America, so-called "age of steam".
Watt died in 18 19. In order to commemorate his great invention, later generations calculated the power of generators and motors.
Bits are called "watts" The power of electric lamps, electric heaters and electric irons used in modern families are all called "watts", which is "watts"
The abbreviation is also to commemorate his outstanding contribution to mankind.
