That's 1736 65438+ 10/9, born in Greenock, Scotland, England. His father is a carpenter, engaged in shipbuilding and navigation equipment business, and is also a joint-stock owner with several wooden boats. He is a rich and powerful man in the local area. Watt was born sickly and often suffers from migraine and toothache. These pains still tormented him until middle age, leading to Watt's mental symptoms of fear and paranoia. Especially when he suffered setbacks, he was particularly prone to depression and self-pity and lost the courage to do anything. So he is unsociable and timid in doing business. Interestingly, however, the older he is, the better his physical condition is, and he actually lived to 83 years old; Moreover, after the invention of the steam engine, he also started a company to do business with others. Some things are really unexpected. Watt didn't like school very much when he was a child, but he liked reading, especially math. Moreover, he has a gift for craftsmanship since he was a child. He often plays with various musical instruments in his father's shop and makes many models with his father's tools. At the age of seventeen, my mother died. At the same time, all my father's boats sank, business was not smooth, and my family suddenly became poor, which led to Watt having to stand on his own feet. But what can he do when he is weak? Selling labor, he is incompetent; Doing business is not in line with his personality; What shall we do? He thought for a long time and secretly decided, "I like making or repairing musical instruments best, and my skills are good. Why don't I come to work in mathematics or scientific experiments and research instruments? " And I'm sure I will go this way in the future! So he came to his mother's hometown Glasgow, hoping to learn this technology. Although he didn't learn anything here, he got to know many professors from Glasgow University through the introduction of relatives. These professors had a great influence on Watt's invention of the steam engine. After all kinds of efforts, Watt was finally able to work as a mechanic in London-Johnson? Morgan's master is an apprentice at home. In order to make his skills more proficient, he works hard every day and even stays up late. Therefore, it takes the average person three or four years to learn the technology well, and he learns it all in one year. At the end of 1763, Watt was entrusted by Glasgow University to repair a model of a Newco portal steam engine, which opened the way for Watt to improve the steam engine. The biggest disadvantage of Newco portal steam engine is that the piston rotates for too long and consumes too much oil. 1765 One day in the early spring, Watt had a brainwave and made another condenser outside the cylinder to introduce the steam in the cylinder into the condenser for cooling, which not only prevented the waste of steam, but also solved the problems of oil consumption and piston rotation time. After repeated experiments, Watt improved the model steam engine and finally successfully operated it. The next job is to make a real steam engine. However, there is a gap between making models and making real steam engines. The problem before us is that at that time, the joint material was limited, which led to a lot of steam running out of the gap and the machine efficiency was very poor. The second problem is money. During the experiment, Watt had to try again, so he added a lot of extra expenses. Finally, he ran out of money. As a last resort, I have to consult Professor Braque. The professor generously lent him 1200 and introduced an industrialist, who is his student, Mr. Robock. Robb himself ran a mine, and he was very interested in the research of Watt steam engine, so he promised to contribute to the research. Unfortunately, in Robock's factory, the machines are not ideal because of poor production technology. At this time, there was a national economic recession in Britain, many companies closed down, and Robock's company was also affected. At the end of our rope, we couldn't help Watt's steam engine manufacturing, and finally we had to terminate our cooperation. In order to continue the experiment and survive, Watt had to become a surveyor of the canal project. Watt has been studying steam engines for nearly ten years. In order to enable the textile industry and other industries to use the steam engine, Watt accepted Pulton's suggestion and began to study the rotary steam engine (the original steam engine was a kind of "reciprocating" linear motion). In addition, Watt also tried to improve the previous method of starting the piston, putting steam into one side of the steam cylinder, so that the two sides can transport and release steam in turn, so that steam force can be applied to the back and forth rotation of the piston. This kind of machine is called a compound machine. 1782, watt obtained the patent of rotating and compound motor. 1788, watt invented the automatic speed regulating device with telecentric speed regulation. This means that when the speed of the steam engine is too fast, the amount of steam in the steam cylinder can be reduced and the speed can be reduced; On the contrary, the speed is slow. It will also speed up the steam engine, that is, automatically keep the rotation of the steam engine at a certain speed. This equipment is equivalent to the pioneer of industrial automation today. In addition to inventing the steam engine, Watt also invented a printing plate for copying a large number of drawings and documents at work. Watt was also the first person to use drawings to color mechanical drawings, using colors to represent different parts or materials for different purposes. This method has been used to this day.

His great inventions can help people all over the world. The electric light he invented was much more convenient and safer than the ancient candles. Although he met with many setbacks, he continued to study. If he has no perseverance, he will never succeed. With this indomitable spirit, he invented many articles for future generations to enjoy. We can have such a comfortable living environment now because of him. We really have to thank him. Today, we must cherish everything he invented. I respect his perseverance and will not give up halfway. I really want to learn from him.
