However, there is one thing, Hong Tao forbade Wen Xiaoqi to personally conduct the on-line test of the boiler and steam engine, and could only guide the apprentices to install it, and then the apprentices took the slave workers on the ship to ignite the actual test. The current boiler www.biquge.info still lacks pressure and temperature measurement instruments, and there is no perfect protection device, so it basically depends on experience. It is said that it is a cross-era power device, but it is better to say that it is a big bomb, and before the commissioning is completed, it is resolute not to risk oneself, and the dead friends cannot die in poverty.

Hong Tao and Wen Xiaoqi were busy on the slipway all day long, and all the work of building the Virginia-class was thrown to charity, and he also wanted to come over to see how the master built a big iron ship without sails, but was bombarded back by Hong Tao. Steam ships have to be built, but the Virginia class can't be delayed, I'm afraid I can't wait for the fleet composed of all steam ships to take shape, and if I want to go back to the Great Song Dynasty raid, I have to rely on these sail warships. Moreover, Wengya's Atlantic Fleet also needs more Virginia-class to join, and for years to come, the sail warships will still be the main warships of the Alliance.

Not only was it the big iron boat that charity coveted Wen Xiaoqi, but Qi Zu and Cixiang also threw the work of forging cannons and making guns to the apprentices, and ran to the slipway together to help. Hong Tao was a little polite to the two of them, as long as the production of guns and cannons was not delayed, these two chief engineer level people have the right and need to understand the new technology in advance, especially the steam engine.

The two of them are not in vain, and the construction of steam-powered ships is inseparable from these two great blacksmiths. Crankshafts and propeller shafts have to be manufactured by them. This made Wen Xiaoqi very depressed, he thought that this was his Wen family's shipbuilding secret, how did it become an open technology.

"What if you used this thing to drive a hammer? The waterwheel is too cumbersome, and it has to be installed by the river, in case God changes his face and causes a flood or something, even the factory will be unlucky. Over the years, I have repaired many waterwheels, and every year during the rainy season, a few of them have to break. If it can be used to drive the forging hammer, the drilling machine, and the boring machine, the factory can be built inland, as long as there is coal, and it will not disturb the urban planning. ”

Looking at the big machine in Wen Xiaoqi's steel-hulled boat that was steaming with white steam, Qi Zu's eyes were full of little stars. He was a Han from the North, and if he hadn't been forcibly captured by Hong Tao in Jinhe City, he wouldn't have gone to live in the tropics. He was very uncomfortable with the hot, humid environment, and he was already suffering from rheumatism in both legs, and his waist was not very good.

As a result, when I arrived in Sun City, the climate here was even worse than that of Jinhe City, and there was a rainy season for half of the year. The factory in Saba City was built on the plateau, and the climate was better, but the water power there was insufficient, it could not accommodate too many water wheels, and there was no water network to support it, so the transportation was not very convenient, so the large-scale forging process had to be done in Sun City.

"It must be possible, but if you want to build a bigger steam engine, you have to let Xiao Qi use his brain more, I really don't know how to play this thing, I can only pick up the leaks for him." Look at his posture, if he doesn't get the smoking steel-hulled boat out, his father will probably not be able to instruct him when he comes over, can we do it? Uncle Qi, don't worry, you can't eat hot buns in a hurry, take your time. When Xiao Qi gets the new machine out of this ship, it won't be a matter of minutes to build a bigger machine by then. And I think this machine can not only drive the big hammer, but also help you move a lot of heavy castings and ores. Do you remember the rails we got in the mines of Jinhe City? If you were to attach the crankshaft of this machine to the wheels and let it run along the rails with a larger ore cart, how much cargo would you say it could pull in one trip? At least a hundred tons is no problem, you say? ”

The idea put forward by Qi Zu is very reliable, and the birth of a new thing often affects the production and life of the entire human race. Bush's thermal generator is a living example, he tasted the benefits of the steam engine in advance, and now Zizou has seen it, which is a good thing. However, Hong Tao's knowledge of mechanical manufacturing is not enough, it should be said that Qi Zu and Kindness have surpassed themselves, and they can't get the simple machine tools themselves. Therefore, I can't provide them with specific manufacturing details, but can only provide some ideas.

"It's called a dragon car! You drew it on my booklet, a long string of carriages, and it can really run? As soon as Hong Tao said it, Qi Zu immediately remembered that he had seen this kind of thing, not a real thing but a picture.

"You're really confused, I have time to draw a story for you? Whatever I write and draw, it is possible to achieve something. It's not called a dragon car, it's a train! Because it has a large boiler in the front of its locomotive, propelled by burning coal and steam, just like Xiao Qi's ship. The use of the steam engine is not limited to steamboats, hammers, and trains, but if you can make it a little smaller, you can also make a car, and I have drawn it in my brochure, right? "This is Qi Zu, if it is replaced by someone else, Hong Tao plans to do it. It's worth being busy for a long time, this old man is all like a comic book, this kind of behavior is worse than mercy coaxing children with pamphlets!

"The one with a little man sitting in a small room with four wheels? I also thought it was a house that could be moved...... It turned out to be a car! I kind of understand this, if you turn the train you are talking about, the steel wheels are wrapped in a layer of cork, as long as it is not too heavy, you may really be able to run on the hard road. "Qi Zu is really angry, he actually said that the car painted by Hong Tao was a small house, this is not Chi Guoguo's slap in the face, Hong Tao has always recognized his own painting skills.

"You don't need to install cork, you go to Bush, he got Xiao Qi a kind of vulcanized rubber, which is wear-resistant, elastic, and much more durable than cork." Qi Zu is really old, he is very unfamiliar with many new things, not deliberately rejected, but not enough energy, he can only focus on his own scope, and has no time to take care of it.

“…… Why are you going, old man? But Hong Tao soon realized that he was wrong, Qi Zu was not old. As soon as he turned around after speaking, there was no one around, and when he turned around, he saw that the old man was striding towards the dock, and his legs and waist no longer hurt.

"I'm a little tired, go back and sleep for a while! Kindness is here, it's okay to find him if you have something......" Qi Zu didn't even turn his head, and his feet were faster.

"Why did my master go? Didn't he say that he would personally direct the hoisting crankshaft for a while, why did he leave? When Cixiang heard Qi Zu shouting his name, he was more puzzled, and he didn't understand what Qi Zu was going to do.

"Hey, your seventh uncle robbed Watt's job, and now your Grandpa Qi is going to rob Benz of his job again. Boy, think about your seventh uncle's machine, and then keep an eye on what your Grandpa Qi wants to get, neither of them is a fuel-efficient lamp, as long as you learn the skills of both of them, even if you don't do anything in the future, you will be the richest man in the world. Hong Tao knew what Qi Zu was doing, he must have gone to Bush to inquire about rubber, and he would probably go back to the laboratory in Saba City to secretly get a train or a car. When Wen Xiaoqi heard that sailboats don't need sails, it was this virtue, and his eyes were the same as being a thief.

The entire installation and commissioning work lasted for more than two months, and Wen Xiaoqi's steel-hulled ship was finally ready to be launched. This time, Wen Xiaoqi didn't make any more arrangements, installed the deck and cabin of this ship, and according to Hong Tao's instructions, he made a wheelhouse on the foredeck, and the steering wheel was installed here. Now this little iron ship has a bit of an industrial flavor, and although it is still very simple, it should be a product of the nineteenth century at first glance.

"Are you coming or am I coming?" Standing in the cab, Wen Xiaoqi was still pretending to be polite, his mouth was very humble, but he held the steering wheel in his hand and refused to let go.

"Come on, this is the Wen family's ship, according to the rules, the first time it is launched, the master has to raise the sails, and the master does not say it, this ship is still a semi-finished product of the shipyard." Hong Tao will not go to grab this honor with Wen Xiaoqi, so he simply let him be proud of himself at one time.

"Hey, hey, then I'm not going to be polite to you...... Firing! As soon as Hong Tao's last voice came out, Wen Xiaoqi couldn't wait to laugh, and then lowered his head and yelled at the brass pipe on the bridge.

The cockpit is just a decoration, there is nothing in it except the whistle, the microphone, the steering wheel device, and the real operating system of the ship is in the engine room below deck. Since it was a test ship, Hong Tao did not bother too much to deal with the clock equipment of the cockpit and engine room, but followed the communication method between the deck and the lower cabin of the sail battleship, shouting! Shout through the copper pipe.

Soon, puffs of black smoke came out of the chimney, and it was the stoker in the engine room who was using heavy oil to ignite the coal. When the fire is burned, it will take more than ten minutes for the boiler to produce steam, and it will take about 20 minutes to half an hour before the amount of steam can meet the needs of driving the steam engine to do work.

This is also a defect of the steam engine steamer, which requires a long warm-up time to start when the car is completely cold. The reason is easy to understand, just like boiling water at home, the cold water just poured into the pot always takes a while before it boils before it can provide steam.

This is not a problem with the design of Wen Xiaoqi's steam engine, even in the twentieth century, the steam engine still has this problem, and there is no good solution. Many steamships do not completely shut out their boilers even when they are docked, preferring to consume more coal to maintain a certain temperature. In the event of an emergency, the warm-up time will be much shorter.

"Forward one!" Although there is no clock, the operation mode of the steamship designed by Hong Tao is still according to the clock, and the forward and backward are divided into four gears, with the crankshaft speed being the slowest in the first gear and the fastest in the fourth gear.

With Wen Xiaoqi's loud roar, a white steam came out of the root of the chimney, and then the entire hull began to vibrate rhythmically, and the vibration became faster and faster, but the amplitude gradually decreased, and the whole ship slowly moved forward.
