Listening to An Jianhai's detailed explanation, Liu Juntao also nodded knowingly, but he was not only ready to be like the later British, who initially only thought about using the steam engine to pump water.

Of course, Liu Juntao, a guy who only understands the basic principles of the steam engine, does not know that more than two hundred years later, if Watt sees this flywheel, he will definitely burst into tears.

It took Watt several years to figure out the crankshaft connecting rod that transformed the linear motion of the piston into a circular motion, and thus the steam engine changed from a mine pumping machine to a factory power machine, a process that can be described as tortuous.

But it's no wonder, who made the ancient Chinese better understand the principle of transmission? Chinese are proficient in gears, circumferences, and connecting rods, and have long been applied to actual production and life, and the experience in this regard is Chinese far stronger than that of Westerners.

In the Book of Agriculture, there is a waterwheel driving thirty-two spindles, and the transmission in between them is already very complicated, not to mention the elaborate escapement system in the astronomical instrument. The water exhaust blower, on the other hand, is a typical circular motion to piston movement, which is now just reversed.

The boiler has nothing to say, it is connected to the cylinder in the middle by a copper tube. It is said to be a cylinder, but in fact it is just a copper cannon. This was ordered by the gunsmith according to An Jianhai's requirements, and even the fire doors were left, and four were made to be used as steam entrances and exits. The muzzle of the gun was also sealed, and only the connecting rod remained.

Four mouths......

The barrel of the gun, no, there are four copper pipes on the cylinder body, one on the left and one on the left and one on the end, one on the top and the bottom, and there are gates. The lower tubes are connected to the boiler, and the upper ones are connected to a horned chimney.

Looking at this layout, Liu Juntao couldn't help but take a breath, this is still a double-action type!?

After a while, as the fierce fire began to burn, the sound of snorting jets sounded, and the four valves were leaking at the same time.

After a long while, Liu Juntao finally heard the sound of rubbing, the piston in the cylinder was pushed by steam, slowly moving forward, the lever was pushed, the flywheel also shook, and the piston went to the end, which was half a stroke.

The steam inlet valve at the rear end of the customs was installed, the outlet valve was opened, and the steam inlet valve in front of the cylinder was opened, and the steam was pushed from the other end of the cylinder.

Seeing this, Liu Juntao was extremely excited, and he only felt that the hairs on the back of his neck stood up, this is this thing! That's it! If you add the linkage spool valve to achieve automatic back and forth, it will be a mature steam engine in the future!

At this time, Liu Juntao only felt as if he had suddenly won a jackpot of 50 million, and he was ecstatic in an instant, eager to pounce on An Jianhai and kiss him a few times, but the scene in front of him had far exceeded his expectations.

But after waiting for a long time, the piston did not move, and saw steam spewing out of the valve and chimney.

At this time, Liu Juntao was also slightly stunned, and the excitement in his heart also dissipated a lot, but there were still some regrets mixed in with it, and he said secretly: "It seems that I am still happy too early!" ”

And An Jianhai next to him was in pain, sweating up and down to check up, obviously a little anxious, and shouted: "I can push it back before!" How could this be? ”

Air leakage, air leakage is too serious, and the boiler is directly boiling a pot of water, how much steam can be produced in this way? Huang Zhuo's approach is correct, and he will indeed no longer rely on condensing steam to do work in the future, but with the current material technology and thermodynamic achievements, it is still unknown how young it is to build a mature high-pressure steam engine.

But even so, Liu Juntao is very satisfied, after all, the Military Department's Armament Department and R&D Department have developed the "steam engine" in front of him only with the drawings they have drawn, which is already very successful!

Liu Juntao patted An Jianhai, who was pale and felt that he had messed up, and said: "It seems that you still have to figure out the principle of vacuum induction, don't be discouraged." Now there are four problems to be solved, the first is of course less air leakage, the second is to design a set of things, instead of people to open and close the gate, so that it can continue to move on its own, the third is to find a way to produce more steam, and the fourth is to add condensing steam method, suck forward and push back, so that the force should be enough. ”

Liu Juntao said this, An Jianhai also hurriedly found a charcoal pen to record it, for fear that he would miss any important points carelessly.

Then, Liu Juntao waved his hand, pointed at An Jianhai heroically and said: "This is already a great success!" You come to be in charge, you want people to give you people, and you want things to give you things! Give you another 10,000 taels of silver, whatever you want, there is no time limit, just bury yourself in researching this matter! ”

Hearing this, An Jianhai and a group of craftsmen under him were overjoyed, and they patted their chests and promised to go all out, which was great news.

Although the steam engine in front of him is still far from the finished product, and even the practicability of the mine pumping machine in later generations has not been reached, but this direction makes Liu Juntao extremely happy.

In addition, there are two other groups of people who have also made progress, Liu Juntao also went to see by the way, one group is honestly taking the road of condensing steam, almost in strict accordance with the general design of the drawings drawn by Liu Juntao, but also uses a flywheel, anyway, this technology is already a rotten thing in Daming at this time.

But their group still uses the single-action principle, pushing and pulling. Because of the condensation process, although the flywheel turns once, it has to wait for half a day before making a second turn. Again, air leaks are severe.

The third group performed even worse, not even pushing the flywheel, but this group seemed to have a deeper understanding of the principle of steam generation, and actually wrapped the cylinders in asbestos cloth to prevent the steam from condensing too soon and too quickly.

After looking at them all, Liu Juntao also had a comprehensive understanding of the situation of the three groups of the Yushan Military Bureau.

Among these three groups, one group mastered the double action, the second group was groping for condensation, and the third group had a vague understanding of thermal efficiency, so Liu Juntao decided on the spot to merge the three combinations, and all the three groups of craftsmen were given bonuses, at least two hundred taels each!

As soon as Liu Juntao's words fell, An Jianhai and the more than 30 craftsmen around him all cheered, and everyone was full of energy.

Two hundred taels of silver is enough for ordinary people for more than ten years, or even a lifetime!

Then, Liu Juntao, accompanied by Xiang Qun, Minister of the Military Department, Zhang Baigui, Director of the Military Armament Department, and Yang Liben, Director of the Research and Development Department, took a turn around the Yushan Military Bureau, then left here and returned to Jinan Fucheng via Yushan Town.

When Liu Juntao returned to the General Military Mansion, he happened to run into Lan Siqi, the head of the Central Committee.

"What's the matter?"

Liu Juntao asked a little tiredly, beckoning Lan Siqi to walk towards the middle hall.

Lan Siqi took a stack of documents and said, "Zongzhen, these are the official documents in the past two months, and Zongzhen has been busy with other things during this time, so they are all backlogged. ”

Liu Juntao said: "Is there anything important? If it's just a general matter, the central department will handle it as appropriate. ”

Liu Juntao knows the importance of delegating power, no matter how great his ability and energy are, it is impossible to do everything, so he must delegate power to his subordinates and mobilize the enthusiasm of his subordinates, so as to ensure the smooth development of various affairs.

Lan Siqi pondered for a moment, then said, "The others are all daily documents, and the central department can dispose of them on its own." However, there is one thing that needs to be reported to the head town. ”

"What?"

"During this time, the steel production of various military bureaus has grown steadily, and after the improved smelting process of the R&D Department, the steel quality of our Shandong town has also improved a lot, and it can basically catch up with the high-quality steel mentioned by the main town."

Hearing this, Liu Juntao was also overjoyed, although the steam engine has not yet been developed, it can be regarded as a bit eyebrow-raising, and it is more than 200 years earlier than the West!

Now the steel production and quality of Shandong Town have also increased a lot, especially the quality, with these two good news, Liu Juntao is in a good mood: "That's good!" In the future, we will use this steel to build enough equipment to crush the Tartars, and then fight all the way to the North Sea! Hit Hengross! Go to the ends of the earth! ”

Lan Siqi listened to Liu Juntao's words, and suddenly felt surging.
