c. 1679 French physicist Denis? Barben built the first working model of a steam engine after watching steam escape his pressure cooker. Pen & Fun & Pavilion www.biquge.info about Samuel at the same time? Moran also proposed the steam engine.

1698 Thomas? Seville, 1712 Thomas? Newcomen and 1769 James? Watt built the early industrial steam engine, and they all contributed to the development of the steam engine. 1807 Robert? Fulton was the first to successfully use a steam engine to drive a steamer.

Using scientific theories, Watt gradually discovered the problem with this steam engine. From 1765 to 1790, he made a series of inventions, such as the split condenser, the setting of an insulation layer outside the cylinder, the lubrication of the piston with oil, the planetary gear, the parallel motion linkage mechanism, the centrifugal governor, the throttle valve, the pressure gauge, etc., which increased the efficiency of the steam engine to more than three times that of the original Newcomen machine, and finally invented the steam engine in the modern sense.

Undoubtedly, the steam engine designed by Zhang Feng is more technologically advanced than the first steam engine in the true modern sense in history, because Zhang Feng is a time-traveler and has a technological level that is hundreds of years ahead of the world.

If it weren't for the limitations of the current technology and technological level, Zhang Feng would definitely have designed the steam engine better and more advanced.

This steam engine can be regarded as Zhang Feng's first-generation steam engine, and after the technical level is improved and there is a certain industrial foundation, Zhang Feng will definitely design and manufacture the second-generation improved steam engine.

Even so, after listening to Zhang Feng's introduction, Zhao Zuolin and the others were stunned, there is still such a thing in the world!

In a more popular phrase, that is, the friends were stunned!

After a long time, Zhao Zuolin said: "Boss, this is your invention, it's amazing, this is simply something that can only be invented by gods." ”

"yes, yes, I didn't think that there could be such a thing in the world."

"Boss, you're awesome!"

“…….”

Listening to everyone's words, Zhang Feng was also happy in his heart, Zhang Feng is also a mortal in the end, and he also likes to listen to flattery, Zhang Feng said happily: "Lao Zhao, I have drawn all the drawings, and our next task is to manufacture the first steam engine." ”

Zhao Zuolin was eager to try, "Boss, there is no problem." ”

The manufacture of steam engines naturally starts with parts, one by one, because there are no machine tools, and they are basically made by hand.

Fortunately, everyone has a certain foundation, and with Zhang Feng's guidance, it is quite smooth. When making flintlock muskets, everyone can skillfully use vernier calipers, and they are no strangers to fitters.

Of course, the quality of the so-called hacksaws, files and other tools is far worse than the modern ones, but at least they can be used, these things are made by Zhang Feng until everyone.

In the manufacture of steam engines, everyone has once again come into contact with a lot of new things, such as riveting, such as threads, etc., Zhao Zuolin feels that he has completely entered a new door to learn and absorb these new knowledge.

The steam engine designed by Zhang Feng can only be regarded as a small and medium-sized steam engine, and the structure is relatively simple, and Zhang Feng guides the process, and after more than half a month, the parts of the steam engine are manufactured and enter the assembly process.

The steam engine was about to be manufactured, and everyone was very happy, but Zhao Zuolin felt a pain in his heart, making this steam engine consumed a lot of fine iron, and there was not much fine iron in the warehouse.

These days, in addition to instructing everyone to manufacture various parts of the steam engine, Zhang Feng also completed the design of the first lathe.

This is the world's first true lathe, and although it is rudimentary, it can at least be used and can turn some parts.

The main body of the lathe is made of wood, made of miscellaneous wood, plus some metal parts, in addition, Zhang Feng also found some stainless steel with slightly higher hardness, and made some turning tools, drill bits and the like.

Because the lathe bed and structural parts are made of wood, only some metal parts, it is not complicated, although the design was completed much later than the steam engine, but the manufacturing speed is very fast, and there is a bit of a taste of backwardness.

The steam engine and the lathe were all assembled on the same day.

In the factory, there was a lot of excitement and a lot of people around. Everyone knows, and even many people are involved in the manufacture of parts, everyone wants to see how this steam engine, this lathe is like.

"Look, it's really moving."

"Really, really moved."

Zhang Feng personally checked it, and after making sure that it was correct, Zhang Feng ordered the test machine to begin, and soon after, the steam engine began to work, and the piston began to reciprocate, snorting white steam, and the flywheel rotated, and the speed became faster and faster.

"Success, boss, we succeeded!"

Zhao Zuolin grabbed Zhang Feng's arm tightly like a child, shouting without any image, and the others were similar, and the excitement and joy were overflowing.

Driven by the steam engine, the spindle of the lathe rotated rapidly, and Zhang Feng became interested and took an iron rod that had been prepared a long time ago, which was about a foot long.

Zhang Feng loaded the iron rod on the machine tool, loaded the turning tool, operated it himself, and became a lathe, the iron filings were turned round and round, and the metal rod that was not very regular was turned very bright and very regular.

The guys were stunned again!

Zhao Zuolin and the others were dumbfounded, they couldn't believe it, it turned out that the lathe was used like this, and when they saw this metal rod, Zhao Zuolin thought about the barrel.

Sure enough, after Zhang Feng finished turning the outer circle of the iron rod, he began to drill again, and we know that the lathe can both turn and drill, although this lathe is simple, but it can also drill.

It didn't take long for this iron rod more than a foot long to be processed into a barrel, the barrel of a short gun, and the barrel was taken off the lathe, Zhang Feng said: "Lao Zhao, take a look, how about our barrel." ”

Zhao Zuolin is an expert, and it can be seen from this look that the quality of this barrel is better than the one he built before, straighter, more regular, and more beautiful.

"Boss, I didn't think about it, I can still process the barrel like this."

Zhang Feng said: "We have a steam engine and a lathe, and in the future, some parts, including the barrel of the short gun, can be processed by the lathe." ”

The processing technology of the long gun barrel is difficult, and such a simple lathe will definitely not be able to process it at present, and it can only barely process a short barrel more than a foot long.

Zhao Zuolin said happily: "Boss, great, it's convenient to have this thing, I promise, I will definitely make a short gun with good quality." ”

Zhang Feng nodded, thinking in his heart, finally with the initial results, with the steam engine, with the simple lathe, Zhang Feng is very satisfied.

Zhang Feng thought in his heart, when the steel plant is built and there is enough steel, I will improve the lathe, no longer use wooden lathes, but cast iron, all-metal lathes, so that the accuracy and service life of the lathe will be greatly improved.

In fact, if the steel plant is really completed and put into operation, the benefits will be more than these.

At that time, not only can enough steel be produced, but also tool steel can be smelted according to Zhang Feng's technical level, and qualified turning tools and drill bits can be produced.

With enough steel, you can produce a larger steam engine, can produce a drilling machine, a forging machine, a planer, etc., when the time comes, with a certain industrial base, Zhang Feng's strength will be improved in a real sense.

Suzhou.

Songjiang Mansion is not far from Suzhou, and the traffic between the two is quite convenient, of course, the traffic is mainly by waterway, and the water network in the Yangtze River Delta region is relatively developed.

Early in the morning, Zhang Feng took Yang Shenghai and several entourages on a cargo ship and set off from Songjiang Mansion to Suzhou.

The cargo ship is not big, but there are a lot of cloths on it, these are cotton cloths produced by the Oriental Textile Factory, Zhang Feng went to Suzhou, mainly to discuss business.

Zhuang Chuanlin, the largest cloth merchant in Suzhou, had several contacts with Yang Shenghai in the past, and also placed several orders with the Oriental Textile Factory, and now, the cotton cloth of the Oriental Textile Factory is sold in the Suzhou market, which has a lot to do with this Zhuang Chuanlin.

Zhuang Chuanlin wants to exclusively operate the cotton cloth of the Oriental Textile Factory in Suzhou, Yang Shenghai has reached a preliminary agreement with the other party, this time, Zhuang Chuanlin invited Zhang Feng and Yang Shenghai to come over, is to discuss cooperation.

In the Suzhou market, Zhang Feng also needs such an agent, and Zhuang Chuanlin, as the largest cloth merchant in Suzhou, is undoubtedly the best object.
