Chapter 149: Test Steam Turbine The ladies are dispatched

After Lu Chengxiang left, Zhang Zhimu remembered that in his previous life, oil was calculated by barrels, and at that time, it seemed that the standard for a barrel was more than 150 liters, which was not easy to remember. How about setting a barrel at 150 liters this time, so as not to have to measure it hard later, but in this way, the size of the barrel should be calculated carefully. In the future, coal tar will also be transported from Niutoushan to the smelting field, and a large number of oil drums will be really needed, and the refined oil will also need to be loaded with oil drums.

Thinking of this, Zhang Zhimu made a call to Li Yunhe and told him the standard of oil drums.

In fact, Zhang Zhimu is also very concerned about whether Qingfengzi can extract benzene and toluene. Because with these two things, ***** and anti-inflammatory drugs are produced. However, Qingfengzi is a very strict person, and they haven't called yet. Zhang Zhimu thought for a while and didn't urge again.

Zhang Zhimu wanted to go to Liu Banzhu and Xiao Hongyu to have a look before going to kill Hukou, because this time Liu Banzhu brought back a lot of people from the south, and also recruited some artists from Shaanxi and Shanxi who sang small songs, and recently rehearsed a new play.

But Li Yunhe's call came in again, and Li Yunhe asked on the phone: "Mr. Zhang, are you going to see the steam turbine they experimented with today?" ”

"That should be a look. When to go? ”

"Go now, you wait for me."

Zhang Zhimu knew that he couldn't go to Liu Banzhu and them today, because the test site of the steam turbine was built in the suburbs, and that thing occupied the place and made noise, and it was built in the kiln gang to affect everyone too much.

Zhang Zhimu didn't know much about the steam turbine, but when he was engaged in tertiary production, he went to a power plant to carry out a project at a time, caught up with the overhaul of other power plants, and glanced at the rotor of the steam turbine, but he couldn't say much. But I've heard a little bit about the principle.

The working mode of steam turbine and cylinder steam engine is completely different, simply put, the steam turbine is to spray high temperature and high pressure steam from the nozzle, rapidly expand and reduce the pressure, that is, the heat energy is converted into the kinetic energy of the high-speed movement of steam, and the kinetic energy of the moving steam is used to impact the blades of the steam turbine and drive the rotor of the steam turbine.

Generally, in order to make full use of the energy of steam, steam turbines have several blades. The blades installed on the rotor are called moving blades, and the blades installed on the cylinder are divided into several parts and the blades are called static blades. After the steam is sprayed out of the nozzle, it first expands and impacts the first-stage moving blades, encounters the first-stage static blades through the moving blades, and expands and decompresses after passing through the static blades to accelerate and impact the second-stage moving blades. In this way, several stages of blades are passed all the way through, and the thermal energy of the steam is converted into the rotational kinetic energy of the rotor.

Such a steam turbine is much more efficient than a steam engine, and is also suitable for making more powerful generators. However, the generator he drove could only be a single-stage rotor generator, because it was a high-speed generator.

After Zhang Zhimu finished talking to those who were engaged in steam turbines, in order to study the principle of steam turbines, they also made models out of wood to observe and study the structure and principle of steam turbines. It can be said that their group has spent a lot of energy on the study of this steam turbine. Moreover, the people selected by Li Yunhe are all people who are good at studying mathematics and physics. Because the development of a steam turbine requires them to do a lot of calculations.

Zhang Zhimu told them that they don't have to think too much about it now, just make a steam turbine that can spin. Despite this, Zhang Zhimu did not expect that they would start testing steam turbines so soon.

On the car heading to the suburbs, Zhang Zhimu asked Li Yunhe, "Why is their steam turbine so fast, and it takes time to build a steam boiler?" ”

"They didn't rebuild the boiler at all, they used the steam engine boiler that was eliminated from the lathe, and the steam turbine they got this time was not very powerful, I heard that it was only about one megawatt. The generators they brought were not newly developed, they were replaced by old-fashioned generators, and it is estimated that the frequency of alternating current generated will also be very high. Li Yunhe said.

"Huh! They're pretty good at finding a solution. As long as they can turn the turbine and slowly improve it, it will be much easier. Now it is necessary to solve the problem of whether there is or not, and then we can slowly solve the problem of good and bad. Zhang Zhimu said.

This is a place north of Xiaoling, an isolated compound, which is newly built at first glance. But obviously this place is not isolated from the outside world, because Zhang Zhimu saw both wires and telephone wires pulled over. The smoke coming out of the chimney indicates that the boiler here is working.

Zhang Zhimu and they heard a roaring noise from a distance, which was completely different from the noise emitted by the steam engine power plant. Zhang Zhimu and Li Yunhe looked at each other, and Li Yunhe said, "These guys, they didn't wait for us, they did it themselves." ”

"Haha! As long as it's done. Our primary concern should be results. "With steam turbines, we can build larger generator units." Let me tell you, in the future, large power plants will use steam turbines, which are much more efficient than steam engines. In the future, we will also switch to steam turbines on our ships, which are not only highly efficient, but also occupy a small space. ”

"Can this turbine make a hundred megawatts?" Li Yunhe asked.

Zhang Zhimu knew that in his previous life, 50 megawatt units were eliminated, but he couldn't tell them, "One or two gigawatts can be built." But that's later, and I think if they can make it, they can build 10 megawatts first, and then 100 megawatts. In short, the larger the capacity of a single machine, the higher the efficiency. ”

It's a pity that the boat built on the Lingshui pier is designed according to the steam engine. Otherwise, you can use a steam turbine. Li Yunhe said.

"How can it be so fast, I guess the next ship is built, and there will be no steam turbines mature enough for ships. It would be nice to be able to use it to generate electricity. ”

When the doorman saw a carriage coming, he ran out, and when he saw Zhang Zhimu and Li Yunhe sitting in the car, he quickly pushed the big iron gate open, put Zhang Zhimu and their car, and closed the gate again.

Zhang Zhimu said: "It's okay! The management is very strict. ”

"Of course, this is an important place for scientific research, and idlers are not allowed to enter." Li Yunhe was very proud.

Knowing that Zhang Zhimu and Li Yunhe had arrived, the team that developed the steam turbine came out. Zhang Zhimu looked at their faces with unconcealed joy, and asked, "Looking at your expressions, there must be something good?" ”

The leader of these people said: "Mr. Zhang, you're right. We should give you good news that our turbines are up and running very smoothly. You'll see it in a moment. ”

Zhang Zhimu and them entered the factory, the deafening noise came, Zhang Zhimu said loudly to them: "A layer of sound insulation cover should be added to the equipment, so that the noise can be smaller, otherwise people can't stand it." ”

The team leader nodded and said, "We thought about it, but we really wanted to know if this thing could be used, so we couldn't wait." ”

"Do you have the generator with you now?" Zhang Zhimu asked loudly.

"I brought it, but I didn't dare to add the excitation current, but it was empty."

Zhang Zhimu felt that it was too difficult to speak here, so he motioned to go out and speak.

They left the noisy computer room and came to their office, Zhang Zhimu felt better, and said: "You can't do this, people can't live long in the computer room for a long time." The team leader said, "That cover can be processed very quickly, and it can be much better with a cover." ”

"Also, some of your equipment is very vibrating and you need to add some shock absorbers to the base. The simple shock absorber is ebonite. If you need more strength, you can use steel to make the bracket and inject it with rubber on the outside. Zhang Zhimu said, "In fact, shock absorbers will also be a major in the future." This will be used on our ships, in our power generation equipment, and even in many places where we build bridges in the future. You can do it yourself first. ”

Li Yunhe said: "Mr. Zhang is right, not only do you need shock absorbers here, but also many of our large machine tools and other equipment also have this problem. It seems that I will need someone to study this issue in the future. ”

"Why didn't you add current to excitation?" Zhang Zhimu asked.

"We don't know where to release such a large amount of electricity. So I didn't dare to increase the excitation current, but just tried to control the speed when there was no load. ”

Zhang Zhimu said: "In this way, I see that there is a puddle not far behind your building. You connect a section of delta steel to each end of the three-phase cable that generates electricity, put it in a puddle, don't touch the bottom of the water, and then pour some salt into the puddle. In this way, the water in the electrolysis pool can be consumed. Go for it! ”

These people know a little bit about electricity, so they understand it as soon as they hear it, and this is a safe and practical way. It's just that they didn't expect it. The team leader instructed some people to do this.

Zhang Zhimu asked, "What is the pressure of your boiler?" ”

"Now there is a megapascal, and I don't dare to put pressure on it anymore. We originally envisioned that this small steam turbine could have a megawatt of power, but our calculation level was far from the reality. Intuitively, I estimate that at one megapascal pressure now, without full steam flow, our turbines are not just one megawatt of power. If we increase the pressure to three or four megapascals, we have no problem with the blades, and we have left enough margin. I guess hitting three megawatts should be no problem. The team leader said.

Li Yunhe said: "Your generator can generate up to one megawatt of electricity, but it still speeds up, and it needs to be controlled by voltage and used for a short time." There is no way to detect the limits of your turbine's power generation. ”

"It's fine. I asked Li Di and them to come and see it. They said that as long as you don't work for a long time and do experiments, you can use three or four megawatts in a short time. Because this is the oldest generator, there was a lot of margin left at that time. It's no big problem to give it a try. The diameter of the wire is sufficient. The team leader said.

Zhang Zhimu likes them the most because they have their own opinions and can find and solve problems by themselves. It seems that people now are not as good as they were in previous lives, they just don't have the opportunity to touch new things. As long as they are given the opportunity, they can be very creative.

On the edge of the puddle, a wooden shelf was erected, and a few strings of porcelain bottles were used to hang three-phase wires, and after the connected angle steel was put into the water, they experimented to increase the excitation current, and when the speed of the steam turbine was reduced, they adjusted the steam flow rate and adjusted the speed of the steam turbine. As a result, the output power of the motor reached three megawatts. The generator is heating up a bit. Zhang Zhimu didn't dare to let them move up. As a result, the limit of power generation is three megawatts. This is already a very big deal.

Zhang Zhimu told them: "The company will reward you heavily, and you are creating a new era of power generation today." ”

These people also know that the power plant of the future will never use the steam engine again, and the power plant will henceforth be the world of steam turbines.

Zhang Zhimu assigned them the task of developing a steam turbine that can stably generate 10 megawatts of electricity, and at the same time, he also asked Li Di and them to cooperate in the development of a 10-megawatt high-speed generator.

However, Zhang Zhimu said: "High-power generators also pose new challenges to our boilers. You're also going to develop new high-pressure boilers. Such a boiler has high requirements for safety. There are also a lot of things that are used in a power plant, such as large boilers, which are boiled and burned by grinding coal into powder and spraying into the furnace, and you also have to organize people to study it together. In fact, the power plant is composed of three parts, one is the boiler, one is the steam turbine, and the other is the generator. These three things are a chain, and they are indispensable. ”

After speaking, Zhang Zhimu turned his head to Li Yunhe and said: "We should set up a power development committee to integrate these three parts, so that we can form a joint force." ”

Li Yunhe said: "It's time for this to happen, we need to build power plants in many places, and there should be a special person in charge." However, I think this 10-megawatt generator should be built next to the smelting yard. When the conditions are ripe. We're going to build a 100-megawatt generator set on the side of Niutou Mountain. ”

"Okay, that's it. Alright, we should go back too. Let the brothers celebrate for themselves," Zhang Zhimu said to the group leader, "and lead the brothers to have a good drink tonight." ”

On the way back, Zhang Zhimu said: "This power development committee must be established as soon as possible. Led by this committee, we will set up a boiler factory, a steam turbine factory, and an electric motor factory. In this way, our power development can be on the fast track. ”

"There will also be cable factories, power installation and construction companies." Li Yunhe said, "In the future, if there is an electricity meter, there will be people who collect electricity bills." ”

"I think this power development committee, let's take the lead by Li Di!" Zhang Zhimu said.

"No one can do it but him." Li Yunhe said.

Zhang Zhimu returned home, and only after dinner did he know that Huang Yukun and Zhang Zhimu went to kill Hukou together, and it was already a fuss.

Let's talk about the family first, my cousin first objected to Huang Yukun going out, on the grounds that Erhu was too young. When Huang Yukun said to bring the child, the cousin was even more reluctant, there was no way, the cousin said: "Forget it, I see that Yukun's heart is already wild, and it won't work if you don't go." But you can't take the child out, stay at home and follow me. Anyway, the child is no longer breastfeeding, and this child has always been carried by me. ”

Then there are opponents of Xiaoqing and Xiaohu, their reason is that they can't do without their mother.

These two children can't do without their mother, but the main reason is that they didn't take them there. Zhang Zhimu explained to them: "You don't have a holiday, so I can't take you there." Wait for the holiday in the future. I'll take you to Yangzhou to play. Yangzhou is a good place, don't believe it, ask your aunt. ”

Yang Yulin said: "You are both big children. Your mother is not here, and I am still there. Didn't my uncle say that he would take you to Yangzhou in the future. Yangzhou is a great place. You'll find out when you go. I'm afraid that you won't want to go home when you go to Yangzhou. ”

The two children heard Yang Yulin say this, and pestered Yang Yulin about Yangzhou.

Huang Yukun sighed and said, "This child was born in the midst of blessings and did not know blessings." Back then, drinking a little corn paste was a good thing, like now. ”

It's like this at home, and it's even more lively outside. In addition to Chen Yufeng's agreement that Sister-in-law Xu went with him, Yan Boju, Chen Yufeng, Zhang Bengui, Mrs. Zhou Yuji, Red Lady, Mrs. Ningde, including Mrs. Cai, all of them had to go together to kill Hukou. Now it's going to be lively. The army of the ladies of Yaogang will go to kill Hukou to "sweep" together. It's not news.

For this matter, Zhang Zhimu also found Chen Yufeng and Ouyang He, and said, "This matter, it would be good if it was kept secret first." Now I am afraid that the whole world knows that the ladies of the kiln gang are going to kill Hukou. ”

Chen Yufeng said: "If you know, you know, it turns out that we always have a little silver hidden, this time we will go generously, anyway, everyone in the world knows that the people of Yaogang have silver." Let them see it this time. ”

Ouyang He also said: "This time, we should have publicized it everywhere. I see that whenever we go somewhere, we stop and go into the city without stopping. Let more people know that our Yaogang people are here. But the guards have to do a good job, and it wouldn't be good if something happened to them. ”

"The red lady said that they brought a company of female soldiers, and it was more convenient for them to take care of their families." Zhang Zhimu said, "Just bring Li Jingren with a company." ”

This time, the team of Yaogang to kill Hukou was particularly conspicuous, and the ladies in Yaogang had their own carriages. Especially the female soldiers of the company outside the car are particularly eye-catching. Each of them was equipped with an automatic rifle and a pistol, as well as a short spur. Each person has a war horse, a lady's military uniform, and leather boots are polished, which is particularly spirited. The team has already attracted a lot of people before it starts. Everyone in Yaogang knew that there was a mysterious team of female soldiers, but they rarely appeared in the public eye, and this time a hundred people finally appeared, which opened the eyes of onlookers.

These female soldiers were carefully selected and trained by Yang Yulin, and now they are managed by Mrs. Zhou and the Red Lady. Yang Yulin still sent everyone off, and this time her mother, Mrs. Cai, also went to kill Hukou together, and she had to send it even more. But this time, with Yang Jing following her, she was a lot more relieved. Of course, Huang Yukun and Zhang Zhimu will also give it away. Xiao Hongyu, who came with Yang Yulin, said angrily: "You said, my master just doesn't agree with me to kill Hu Kou, not to mention that the rehearsal is tight and I can't leave." You said there were a lot of people this time. ”

Yang Yulin gloated and said, "You are all gone, who will accompany me." You can honestly rehearse at home! ”

Xiao Hongyu didn't say anything, she thought, "You just don't want me to follow Zhang Zhimu, and say that I will accompany her!" But what comes out of my mouth is "Yes!" We are good sisters, how can I leave you alone in the kiln? ”

Because this time I walked a few days in advance, along the way, the team of Yaogang had to go in to take a look when they met the state capital and county, and when they arrived at Yanmen, Zhou Yuji's wife had to let everyone turn around and come to Ningwu Pass.

Zhou Yuji had already received a telegram from his wife, and had already arranged the reception. The reception should be said to be extremely attentive.

At night, Zhang Zhimu and Zhou Yuji will of course be drunk. However, before drinking, Zhang Zhimu introduced Liu Yun and their situation to Zhou Yuji, as well as the emperor's request for Zhang Zhimu and them to attack outside the pass, and this time they were going to kill Hukou and wanted to buy a piece of land in the pass to prepare for the garrison.

After listening to Zhang Zhimu's words, Zhou Yuji said: "Zhang Dongjia, why am I a little confused. When you beat Li Zicheng away, took the whole of Shanxi, and went to the area north of Yanmen Pass, I realized that you were handing over the burden of dealing with the northern frontier to the imperial court, and I threw myself into the ground for the five bodies that you admire. In this way, it will not offend the court, but also save worry. But if you go out this time, will you take over the burden of the north? ”

Zhou Yuji asked the same question as Li Yan, and Zhang Zhimu had no choice but to explain to Li Yan again.

Zhou Yuji nodded when he heard this.

Zhang Zhimu said again: "Mr. Zhou, by now we should say that he is not an outsider. Even if the situation changes in the future, we will have to take over Yanmen Pass and other places outside Yanmen Pass, and we will not guard it like the imperial court. If you don't talk about it elsewhere, let's just say that starting from Yanmen Pass, and further north in this section, how many soldiers and horses will be arranged by the imperial court in the area of Datong, Biguan, and Hukou. I don't know when the Tartars in the north will slow down and kill them, and we must always be prepared. How much manpower and material resources are wasted. But if you think about it, if we step out and occupy a place outside the Great Wall, then we don't need to have so many troops in these passes here. At that time, the Mongols wanted to fight, and we fought in their steppes. Isn't it better like this. ”

"Oops! Zhang Dongjia is really a master, at that time, Yanbei was in the rear. I've heard that you want to build the railroad to the point of killing Hukou, and that's even more so at that time. Zhou Yuji understood Zhang Zhimu's approach.

Zhang Zhimu said: "There is another secret that I want to tell you. Confidentiality is required, though. ”

"Don't worry, I know the severity!"

"Our plan is that if there are no accidents, we are ready to build the railway to Baotou the year after tomorrow."

"Fix the railroad outside the gates? How dare you think about it. I'm afraid that the emperor won't agree. Zhou Yuji was surprised.

"Why keep it secret, it's here. At that time, the emperor did not agree that we should also repair. With this railway, we can ensure that we can take root outside the border. Zhang Zhimu said very firmly.

However, Zhou Yuji has more experience with Zhang Zhimu's words, "The emperor does not agree with us, and we have to repair it." That is to say, even if they turn against the emperor, they will do it according to their own ideas. What this means is already clear.

Zhou Yuji saw that the people of Yaogang really didn't treat themselves as outsiders, and said: "Zhang Dongjia's words are said to be this, they really don't treat me as an outsider." Let me also say from the bottom of my heart, I am very supportive of your practices everywhere in Shanxi. What are you doing, don't pull us down from Ningwu Pass and Yanmen Pass. If because I am here, the people here will not get the benefits of the kiln gang people, and I will be a sinner! ”

"Mr. Zhou, don't get me wrong. With you here, if we put our hands here, we don't feel righteous. Today we talked about it, and we will come over to discuss what we have in the future. However, I think it's better not to let outsiders know that we have been in a close relationship. It will take us a few years to recuperate. Zhang Zhimu said.

"In this case, I also suggest that you try to get the emperor's support for everything, and you should approve it at the very least." Zhou Yuji said.

"Of course, what we are doing now is what we are told." Zhang Zhimu has already felt Zhou Yuji's pulse.
