Chapter 173: Shanxi General Soldier Zhou Yuji

Zhang Zhimu, who returned to the office, spread out the drawings and wanted to design the big generator as soon as possible. The so-called big cannot exceed ten kilowatts, because the power of the steam engine is limited. Now it is unrealistic for Zhang Zhimu to design a generator theoretically, in his previous life, he only knew the principle of the motor, and he had disassembled and assembled the motor. However, it is impossible to theoretically design a generator with this knowledge. However, Zhang Zhimu feels that his predecessors developed on the basis of no theory, and I have learned so many theories. It should be better than their base, and without precise calculations, leave a margin a little larger. If the power of the generator is 10 kilowatts and the output voltage is 220V DC, then the current is 45.45A, and the 11 kilowatt three-phase motor in the previous life should use 10 square wires, so I will leave it larger and use 15 square wires. In addition, the electrician's mantra "five out of ten, four in the middle of a hundred" is memorized. According to the calculation of four amps per square meter, it is also 11.36 square meters. So a line of fifteen square is sufficient. In order to reduce the skin effect and facilitate installation, a five-core 3-flat copper wire is used. The excitation current of a DC motor should be one to three percent of the armature current. If you take a larger one and calculate it by three percent, it should be 1.36A, and take an integer to calculate 1.5A and use a 0.5 flat line. If the voltage is calculated as 1.5A at 220V current, the resistance of the excitation coil is 147Ω. This requires 0.5 square meters of copper wire length = 147/(0.0175/0.5) = 4200 meters.

As for the length of the armature winding wires, Zhang Zhimu can't figure it out. However, according to the size of the excitation pole, the size of the armature is designed, and then according to the size of the slotted to see how long the copper wire is. In short, everything is to be explored, and there is no one to guide you here, and there is no information to look up. Anyway, don't care about the efficiency or the cost, just try it.

However, there is a difficulty, that is, how to control the output voltage by adjusting the excitation resistance, because due to the different loads, the output voltage must fluctuate, in order to stabilize the voltage, it is necessary to adjust the excitation resistance to achieve it, and control the excitation current to achieve it, but the current means are really limited.

There is no way, only to use the device of rotating the small hammer of the steam engine to adjust the excitation resistance. The method is to connect a small motor at the output end of the generator, the small motor has a pair of rotating balls, and the speed of the motor is fast when the voltage of the motor is high, and the speed is slow when the voltage is low. When the motor speed is fast, the two rotating balls are lifted higher under the drive of centrifugal force, and vice versa. The slider will adjust a sliding variable resistor, which will adjust the excitation current. This sliding resistor is wound with copper wire.

Zhang Zhimu was racking his brains to design a large generator, and he wanted to concentrate and finish it all at once. Otherwise, if you are disrupted by other things, you will have to come back and re-enter the state, which will be very difficult. So Zhang Zhimu thought it would be better to have something else to do.

But that's the way it is, it's often the fear of something.

Zhang Zhimu and Chen Yufeng and Ouyang He studied Zhou Yuji, the chief soldier of Shanxi, but they didn't expect that Zhou Yuji was also thinking about them.

The guards came and reported: "There is a prince from the capital and the general soldier of Shanxi who have come with a group of men and horses, saying that they want to see you." We stopped him at the post. ”

As soon as Zhang Zhimu heard it, how could things in this world be so coincidental, we just talked about Cao Cao, and Cao Cao arrived.

"Hurry up and notify Mr. Chen, let's pick it up together." Zhang Zhimu commanded.

"It's been notified." After the guards finished speaking, Zhang Zhimu had already left the guards and went to meet them. Chen Yufeng and Ouyang He were waiting for Zhang Zhimu, and when they saw Zhang Zhimu coming out, they walked to the post together.

Chen Yufeng also felt a little strange today, "I look at this person, it's really careless." We just finished talking about this Zhou Yuji, and Zhou Yuji arrived. ”

Ouyang He analyzed as he walked: "He invited the prince out, it is likely that the emperor sent them." If you don't get it, I'm going to bleed. ”

As he spoke, several people had already come to the post.

The prince and the chief soldier of Shanxi, Zhou Yuji, had already dismounted, and were pointing to the windmill of the kiln gang together, watching and talking. Behind them were forty or fifty people, and it was obvious that the people brought by the prince were all brocade clothes and trousers; Others are dressed in black and pants. Apparently these people came out of civilian clothes.

Seeing Zhang Zhimu and the others coming down, Wang Gonggong spoke first: "Hey, hey, you people in the kiln gang are too powerful." They stopped us, and they didn't let us go. I don't have many people in Beijing who dare to stop me. ”

Zhang Zhimu hurriedly said: "Forgive me, princess." The people in our small place are all blind and don't know you, otherwise how dare they stop you. But on this cold day, you don't enjoy the happiness in the capital, and you come to our bitter cold place to find sin, aren't you asking for yourself. ”

"I, I can't see you, I just miss you, I can't help it." The prince laughed and said, "You see that Jing is joking, there is a chief soldier here, and I will introduce it to you." This is the new Shanxi commander-in-chief Zhou Yuji Zhou. ”

Zhou Yuji was dressed as a wealthy gentleman in Shanxi, not tall, but stocky and strong, wearing a black satin cotton jacket and a lambskin shoulder, and wearing a big leather hat. A pair of beards with ringed eyes and sideburns show even more heroic. At first glance, this is a tough guy who has been in the military for a long time. Especially his eyes, it's not that he can't emit that kind of light after a long time of battlefield experience.

Zhang Zhimu hurriedly saluted and said: "I have heard the prestige of Lord Zhou for a long time, and it is the blessing of our Shanxi people that you came to Shanxi. ”

Zhou Yuji was also busy arching his hand and said: "Where is it, I have also heard of Zhang Yishi's name for a long time. I sincerely admire what you have done. I've been wanting to visit for a long time. When I took office, I passed by Tongguan, where General Ningde was garrisoned, and Zhang Yishi was even more respected. told me that if you want to defend Shanxi, you must get the support of Zhang Yishi. ”

The prince said beside him: "Come on, two, it's time to compliment each other." On this cold day, Zhang Dongjia should quickly get us something hot to eat. You have to drink enough of your good wine from the kiln. ”

Zhang Zhimu hurriedly let the two of them to the post with Chen Yufeng, and Zhang Zhimu said, "Let's go directly to the canteen." We sat and chatted while waiting for the food. ”

Wang Gonggong made the decision today, and said: "General Zhou Bing, I think our guards will be arranged by Zhang Dongjia." Our safety will be handed over to Zhang Dongjia, in fact, we are a little bit of people, and it is okay to go out to tigers and tigers. What is the use of the kiln. ”

Of course, Mr. Zhou will not object, "When I arrive at the kiln, I will listen to the arrangement of the kiln." It also opened the eyes of these guys who usually feel that they are not ambiguous. ”

Chen Yufeng went out for a while and arranged for Liu Yun to receive these guards. These guards, who usually follow the general soldiers and the princes, are very majestic. But these people are not fools, they know that both the Mongol cavalry and the Manchu iron cavalry have been defeated by the Yaogang people.

Liu Yun: They came forward to entertain them, which was already very face-saving for them.

Chen Yufeng, who returned to the table, asked people to bring in a few jars of wine by the way.

Seeing these jars of wine, Zhou Yuji and Wang Gonggong's eyes lit up.

Zhou Yuji smacked his lips and said: "Along the way, the prince kept telling me that the fine wine in Yaogang is not good for how much you drink. I've been thinking about this wine all the way. ”

The prince obviously couldn't wait any longer, but they still knew the severity, and said, "Okay." They hurriedly took advantage of the fact that they hadn't drunk and got down to business. After that, let's let go of the amount and have a good drink. ”

Zhou Yuji is also a cheerful person, "Then I'll talk about it first." It was only in November this year that I received an order from the imperial court to transfer me to Xu Dingguo as the chief soldier of Shanxi. When I led my troops to take up my post, I got a report that more than 70,000 people of the Manchu Qing Dynasty had broken through the wall and entered the customs and plundered in Zhongshu Province. When I arrived with my cavalry, the Qing army had already been repelled by Zhang Yishi and Wang Gonggong. Oh, when I heard the letter, I was happy and ashamed. Happily, the Qing army was finally repulsed, and the people of Li were able to suffer less; It is a shame that our dignified officials and soldiers are not as good as businessmen like Zhang Dongjia. Usually, the imperial court raises us, but when something really happens, it actually lets our people go into battle on their own. I'm so ashamed. ”

Wang Gonggong took over and said, "Zhang Dongjia is not an ordinary businessman. After repelling the Qing army, he did not pursue the fleeing Qing army, leaving the opportunity for meritorious service to me. But he himself cleaned up the battlefield and quietly retreated. ”

Zhang Zhimu knew that the prince understood, he sent the prince away, but he took the opportunity to receive what the Qing army left behind, and the prince felt a little unbalanced about this. Zhang Zhimu pretended to be confused and said: "The prince has made a great contribution this time. You must have been rewarded by the emperor, right? ”

"That's right, otherwise I'll be sorry for the Zhang family." Wang Gonggong said with a wry smile.

Zhou Yuji heard it, there must be a lot of secrets between these two people. He also knew that these were not something that he could do with a small general soldier. He had no choice but to go down to himself: "After I arrived in Shanxi, when I saw it, it was no wonder that the army led by Xu Dingguo broke up overnight when they arrived in Qinshui. What kind of soldiers are they, they are all old, weak, sick and disabled. It would be nice to be able to walk there. After I took office, I eliminated the old, weak, and remnant soldiers, repaired weapons, strengthened military training, and prepared for war. However, I have also found that our soldiers have been short of food for a long time, and it will take a while for them to recover their physical strength, and it will take even more time for them to train their soldiers. However, the situation in Shaanxi on the other side of the Yellow River is becoming more and more dangerous, and the Yellow River between us and Shaanxi is more than 1,000 miles. So I asked the imperial court for more troops. However, the court soldiers were not sent, but the prince was sent. ”

The prince took over and said, "Where is the imperial court to send soldiers now?" So the emperor asked me to come in person and ask Zhang Dongjia for help. ”

Zhang Zhimu smiled bitterly and said, "Asking me for help?" When you came, you all saw that the little kiln was full of sheds. Tens of thousands of people came at once. Last time, the prince must have thought that after you left, how many things did I get from the Qing army? I'll tell you, we get the most out of the people they didn't take. If we don't care about them, these people in the ice and snow will have to freeze to death. So I brought them all back. ”

Wang Gonggong smiled and said, "Don't misunderstand Zhang Dongjia. The emperor thinks that you can win the battle with the least number of troops, and a large part of the reason is that you have muskets. This time, the emperor sent me over, firstly, to escort some silver for General Zhou's soldiers, and on the other hand, the emperor felt that we had cooperated and were very familiar with each other, and wanted me to tell you about it to see if I could buy some muskets from you. In this way, there is no need to send troops to General Zhou, if their existing soldiers can be equipped with some muskets, their combat effectiveness will be greatly improved. ”

"Before I took office, I went to Tongguan, and I also saw the musket you gave to General Ningde, and Ningde repeatedly said that with the musket, Tongguan is impregnable. I also saw the power of the musket. What's more, you used only a few people to defeat both the Mongol cavalry and the Manchu cavalry with this musket. This not only shows that you kiln people can fight well, but also shows the power of muskets. Mr. Zhou's words were very rigorous, not at all like the impression he suddenly gave people. Zhang Zhimu concluded from this that this person is a person who can fight with his brain, and he is definitely not a reckless man.

may be afraid that Zhang Zhimu will refuse, and without waiting for Zhang Zhimu to speak, the prince said: "Zhang Dongjia, the emperor knows that this musket is not easy to make, and after the musket you gave to the Ministry of Industry, they have been copying it." But it took too long to make a gun. So the emperor said that you must not be allowed to accompany the musket. I think it's okay to follow the price you gave to Datong Jiang Zongbing? ”

When Zhang Zhimu saw them say this, he knew that before they came, he had already understood his connection with Datong and Tongguan very clearly. It seems that the efficiency of Jinyiwei is still very high. Even his own business with Datong is clear.

Zhang Zhimu said: "Don't hide it from the two of you, I have a slight loss in my business with Jiang Zongbing. As the prince said, it is too laborious to make the barrel of a musket. And there is no other way to do it, but to grind little by little. But why did I sell it to him anyway? It is because General Jiang has muskets and can firmly guard the northern border, and we have a sense of security. Therefore, even if you pay again, you must also do this business. ”

When Zhou Zongbing saw Youmen, he took over and said: "Zhang Yishi, I think the current situation in Shanxi is that the danger in the west is even more critical than that in the north. If possible, we would also like to buy a thousand muskets first. ”

Wang Gonggong hurriedly said: "Don't worry about the silver, this time the emperor allocated some silver to the general soldiers of Zhou, and the Yamen of the general soldiers of Shanxi still has some silver, and there is also a lot of silver that has been confiscated from Xu Ding's country." This time it was all left to Mr. Zhou. ”

Zhou Zongbing continued: "In fact, our Shanxi General Soldier Yamen also has some of its own sources of income. If we can, we can also exchange supplies for muskets, just like General Jiang in Datong. We don't have copper there, but we have a lot of coal. ”

Zhang Zhimu smiled bitterly and said, "It seems that I just don't want to sell it." ”

When Wang Gonggong saw Zhang Zhimu say this, he felt very embarrassed, "That's right, Zhang Dongjia." If you support General Zhou to keep Shanxi, you are protecting yourself. ”

Zhang Zhimu said: "I agree to the request of the two. But time can't be rushed. Because Datong Jiang still has 500 muskets that have not been delivered. "Actually, these 500 muskets have already been made, because it is cold, and I want to wait for the beginning of spring to send them. This can also make them feel that it is not easy to grab production.

As soon as Wang Gonggong saw that Zhang Zhimu agreed, he interrupted the conversation between Zhang Zhimu and Zhou Zongbing and said, "You guys are all coming up, I can't wait." I don't get involved in business. You guys talk slowly tomorrow. Today, from now on, is drinking. Everything else will be discussed tomorrow. ”

Zhang Zhimu and Zhou Zongbing also thought that they would have time to talk about things slowly. They both feel like they need each other.

As soon as this wine was drunk, Zhang Zhimu quickly became a supporting role. Chen Yufeng and Zhou Zongbing can be regarded as opponents in wine, but what Zhang Zhimu didn't expect was that Ouyang He, who was polite and polite, could also have a drink with Wang Gonggong to meet opponents.

At the wine table, everyone can be regarded as heroes and heroes. Each talked about their own different experiences. What interests Zhang Zhimu is that Zhou Yuji was born in Jinzhou, which is where Zhang Zhimu was born in his previous life.

Zhou Yuji was brave and good at shooting, and after joining the army, he was extremely brave in the battle against the Later Jin, and was gradually promoted from an ordinary soldier to the Beijing camp guerrilla of the Ming Dynasty army. In the ninth year of Chongzhen (1636), the Qing army attacked Beijing. Zhou Yuji followed Shangshu Zhang Fengyi in several bloody battles, and was promoted to two levels in a row and promoted to the deputy general of the forward battalion.

Later, he made great contributions to many battles against the peasant army, and was a general who gradually rose from the lower ranks.

Chen Yufeng also used the strength of wine to tell everyone about his extraordinary experience.

Zhou Yuji and Chen Yufeng, two people with completely different life experiences, admired each other very much and became good friends.

Zhang Zhimu and Chen Yufeng drank very well here, and Liu Yun also drank well, especially because they were both from martial arts training. As soon as Liu Yun reported the number, many people got up directly to give gifts. There are a few of them who are still Liu Yun's apprentices. According to the rules in the martial arts, when you see your uncle, you must give a salute.

When the wine is almost drunk, the heroes who cherish the heroes have nothing to talk about. After drinking, Liu Yun led them all to the bathhouse. Liu Yun asked the bathhouse to change to a pool of new water, and let everyone take a hot bath together. Many of these people are taking hot baths for the first time, and they are very happy now.

Zhang Zhimu arranged it like this, and Liu Yun understood very well that this was to win them one day and leave an impression first. Otherwise, it would not be Liu Yun's turn to accompany them personally.

The next day, the business negotiations between Zhang Zhimu and Zhou Yuji were much simpler. Zhou Yuji wanted to buy a thousand muskets, each with 100 solid bullets and 100 shotguns. The musket was a thousand taels of silver, and the bullets were ten rounds of a tael of silver.

Zhou Yuji also had to buy a steel spring carriage, and the number was as much as that of Jiang Zongbing in Datong. Later, Zhang Zhimu learned that Zhou Yuji was bought by Jiang Zongbing.

However, Zhang Zhimu only accepted a quarter of the payment for the goods with coal, and required that the coal be transported to the smelter before it was counted. The rest is that every time a batch of products is made, Zhou Zongbing will be notified to take the money and pick up the goods.

Zhang Zhimu also said that the muskets will be produced as soon as possible, and when the first batch of guns is produced, Zhang Zhimu will send instructors to train them personnel, just like in Tongguan. In fact, Zhou Yuji didn't know that the process of these trainings was also the process of the instructors contacting their key personnel.

After talking about business, Lu Chengxiang went to sort out the paperwork.

Zhang Zhimu pulled Zhou Yuji to a map, pointed to a red line from Yaogang to Kill Hukou and Zhangjiakou, and said: "Next year, we are going to rebuild this road, improve the conditions for the opening of this road, and strive to make the carriage run on the road after the repair." We're also going to have stops along the way, so we can start passenger and freight traffic. In the future, the transportation and living conditions at the border gates will be greatly improved. ”

Zhou Yuji was crawling and fighting, of course he knew what the impact of the improvement of traffic conditions in his defense area would be.

Zhou Yuji said: "What you did Zhang Dongjia should have been done by the imperial court, but now you have done it with money." ”

Zhang Zhimu said: "When the border is stable, it will be much safer for us to do business." After the four seas are calmed down, I don't have to bother with these things to train the Self-Defense Forces. ”

Zhou Yuji said: "The road has been repaired, and no matter who has trouble on both sides of us in the future, we can easily support each other." ”

Hearing this, Zhang Zhimu asked Zhou Yuji: "General Zhou, what methods do you use in your army to exchange information now?" ”

Zhou Yuji said: "Just send someone to report it quickly." There are also carrier pigeons. Near with trumpets and drums. ”

"Next year, we plan to build a telegraph line from Yaogang to Lingshui Wharf, so that we and Lingshui Wharf can communicate in real time." Zhang Zhimu said.

Zhou Zongbing didn't understand what Zhang Zhimu said about the telegram, and asked: "What is the telegram, I see that there are things everywhere in your kiln that I don't understand." Let's just say, in the house I lived in yesterday. It's heating again, and it's running water. ”

Zhang Zhimu said: "The telegraph is much more important than that. Suppose all our checkpoints are connected to the telegraph network, and any point of matter can be reported in real time, rain or shine. So what does the chief soldier think? ”

Zhou Yuji didn't answer and asked: "Can Zhang Dongjia tell me about this telegram?" ”

"Want to know about the telegram?" Zhang Zhimu smiled and said, "Then come with me!" ”

Zhang Zhimu led Zhou Yuji to Li Di and Yang Chang's test site. Zhang Zhimu asked Li Di to explain to Zhou Yuji how to send and receive the report in combination with the real thing. Zhou Yuji didn't speak at that time. But leaving Li Di's test site, Zhou Yujila Zhang Zhimu's hand said, "Brother Zhang Xian, this thing must be kept secret at all." When you repair the line to Lingshui Wharf, if you have any problems, if you encounter trouble, I will come forward to solve it for you. Zhou Yuji's name for Zhang Zhimu has been changed to Zhang Xiandi, and he has shown great interest in the telegraph. With the sensitivity of a soldier, he knew that this thing had to be kept secret.

Zhang Zhimu said: "What's the matter, when my telegraph line is repaired, please come and take a look?" ”

Zhou Yuji was no longer interested in this telegram, he said: "After the matter is completed, Brother Zhang Xian must inform me, and I will definitely come over to take a look at it when the time comes." If it is really like what the virtuous brother said, I will report to the imperial court, let the imperial court, and install a telegram on all the border gates, and at that time, the imperial court can understand the situation of the border gates at any time, and the border gates will be much safer at that time. ”
