Three people went back to the 99 community and pushed the door, but now Li Yuanling is also home. Liang Yuan and two loli changed their shoes and entered the house. Liang Yuan put a big bag of food and two pieces of sand in his hand and breathed a sigh of relief.
After greeting Li Yuanling, the two girls went to the bedroom to write.
Liang Yuan asked curiously, "Why did Mom come back so early today?" Li Yuanling seldom goes home before nine o’clock at ordinary times.
"Mom is going to lose her job," Li Yuanling said cheerfully.
"Oh, mom decided to re-establish the project team?" Liang Yuan got excited and worked so hard to get so many things. In the final analysis, Li Yuanling got the gas turbine in his hand.
"Xiaoyuan can’t see your figure these days. Your father said that you have been staying with your brother-in-law. What are you busy with?" Li Yuanling did not answer Liang Yuan’s question.
"The 243-type locomotive has signed an import agreement. In the past few days, I accidentally met an engineer who is a microprocessor. I had a special chat and asked my brother-in-law to dig people up." Liang Yuan roughly told Li Yuanling about his experience these days.
Li Yuanling and Liang Jiangping have also had a headache for a long time since they learned that all the stalls in Northeast Locomotive Works were made by Liang Yuan. Facing the complicated situation, both of them feel difficult. After all, the nature and production of Northeast Locomotive Works are very different from those of ordinary enterprises. Looking at hundreds of millions of assets, both of them are at a loss. Liang Jiangping intends to merge Suifenhe Market with Northeast Locomotive Works, which is a good thing and a bad thing. No matter whether Northeast Locomotive Works can successfully switch production, there will be a big market that will not go bankrupt for ten years.
Li Yuanling rejected Liang Jiangping’s suggestion. Li Yuanling said that even the Northeast Locomotive Works is my son. However, when these equipments are handed over to the national defense industry, our family recognizes that Suifenhe market is a small patent, which conforms to the principle of promoting labor to get rich. Why should we hand them over? There are two little girls in Suifenhe market.
Ning Lei Liang Jiangping of the United States lost an ally, and Comrade Jia Laoliang’s family always had no position. This matter was finally thrown to Li Yuanling and Tang Wan for handling.
To Tang Wan, it is obvious that the Northeast Locomotive Works is Liang Yuan, and it is already a shame to hand it over to the country. Just let Liang Yuan do it himself and practice it. Anyway, several people in front of Liang Yuan have fallen into bankruptcy in the future, and others can’t say anything.
Li Yuanling, though she thinks that practicing in such a big enterprise as Liang Yuan is extravagant, has not found a better way to deal with it than Tang Wan. Of course, this purpose must not be known to Ning Lei and Liang Jiangping.
After Liang Haiping, the junior class of Liang Yuankao, successively introduced double-decker underbody and 243-type locomotive from the Democratic Republic of Germany, several adults completely let go of Liang Yuan, so now Liang Yuan has nothing to hide, just say it when someone asks.
"Xiaoyuan intends to let your brother-in-law do industrial automation?" Li Yuanling asked.
"Well, that’s one aspect," Liang Yuan said with a smile. "The most important thing is to get mom’s gas turbine." To be continued.

Chapter 55 Gas Turbine New Application
Spey motor is the second generation control system, which belongs to the hydraulic mechanical control system. The realization of motor control law mainly depends on cam surface to complete the control accuracy. Although Spey control system is very reliable, it is difficult to control cam manufacturing, which also accounts for the limited motor and increases the weight of the motor.
Limited digital control system belongs to the third generation control system, which has great advantages over hydraulic mechanical control in terms of light weight, small proportion and high control accuracy, fuel consumption, reliability and cost.
For example, improper operation of hydraulic control motivation is easy to cause loss, so that the digital control system can solve the problem well. When the aircraft just shows signs of loss, the microprocessor can take immediate measures to eliminate the loss and greatly increase the aircraft safety.
Li Yuanling naturally knows the advantages of limited digital control system in detail. Looking at Liang Yuan stumbling and showing off his miserable knowledge of motivation control system, he couldn’t help laughing. He pulled up Liang Yuan and rubbed his head. Liang Yuan smiled and said, "Don’t take out your knowledge. Mom certainly knows that the microprocessor is a core digital control system, but you said that the temperature of ordinary chip makers is about 100 degrees at most, and you want to make the chip fly so that the chip must be stable at 3 degrees high temperature."
Liang Yuan Kabakaba’s eyes said, "Anyway, mom doesn’t study aero-engine to be a gas turbine now, so she can put the digital control system far away from the engine."
Li Yuanling suddenly understood Liang Yuan’s meaning, and the conversion from mechanical control to digital control can’t be completed overnight. It takes a long-term ground test run. Liang Yuan said that the current digital control system wants to lay the foundation before the chip passes, and then directly to the motivation.
Li Yuanling thought it was particularly interesting to think about Liang Yuan’s careful thinking. She thought that a layman is a layman after all. It is only necessary to change the chip. I don’t know that every millimeter of the current flight motive needs to be accurately calculated, and the weight change per kilogram involves a lot of calculations. Besides, the digital control system of the aircraft is very difficult even if the experiment is done on the ground, but the ship power or Liang Yuan’s discussion is still valuable.
Li Yuanling didn’t dampen Liang Yuan’s enthusiasm, but she said with a smile, "Mom will wait for you to hire an engineer, but I heard from your brother-in-law that you have been acting furtively recently and today you took the initiative to come to your mother to pay tribute. What the hell are you thinking?"
Liang Yuan is hey hey smiled and asserted that it is a career contribution and will never admit that he has his ghost mind.
Two people chatted for a while for gas turbine Liang Yuan. Only then did they know that Li Yuanling had printed the information sorted out in the previous paragraph into a file and gave it to the whole project team. Li Yuanling decided to re-determine the research direction, modify the prototype in strict accordance with the s_a1 drawing of Spey, and prepare to rectify the structure of the project team and implement the overall responsibility system.
This document is equivalent to throwing a boulder in a calm pond. Except for a few young people in the whole project team who expressed their support, most people in the 423 factory strongly opposed the project deputy chief engineer, Tao Yonghe, a professor-level senior engineer in the 423 factory, and directly threw the information compiled by Li Yuanling into the trash can in front of everyone and scolded nonsense.
Professor Tao Yonghe generously said, "The country’s scientific research from poverty to poverty depends on the collective efforts of scientific and technological workers to bring forth new ideas. Li Yuanling’s rectification data management denies the successful experience of scientific research in China since the founding of the People’s Republic of China, and academics also cringe, overemphasizing and exaggerating the technical difficulties of foreign countries, hitting the innovation enthusiasm of scientific researchers, and the scientific research ideas are rigid and dogmatic."
These days, about half of the researchers in the whole project team strictly observe neutrality and honesty, and the remaining half are divided into two camps, arguing with each other and the gas turbine researchers are completely paralyzed.
Wu Zhonghua is also a headache in the face of this situation. It is already the limit of Wu Zhonghua’s ability to arrange Li Yuanling as the project leader. This storm has involved the core idea of the project team, and it is impossible to continue to muddle along.
In the face of the opposition of a large number of project team elders from 423 factory technicians, Wuzhong Huaneng temporarily stopped Li Yuanling from Beiping and hurried to Shengjing to take up the post of project chief engineer again.
Due to the contradiction between Li Yuanling and the 423 factory, the superficial scientific research face has stopped. Recently, Wu Zhonghua has been trying to make peace with the mud, hoping to resume the gas turbine experiment and research first, but the effect is not good.
Li Yuanling didn’t talk to Liang Yuan in detail about this nonsense. It was simply said that he would no longer lead the gas turbine project team at present, and then he would cook dinner for Liang Yuan and two little girls when he was free.
Liang Yuan turned his eyes and combined with past life memories to make things up. * * I thought for a moment that it was impossible for the old lady to plaster and say that Xiaoyuan gave her mother ten million to study the gas turbine, and she also took the initiative to dig a hole herself.
"Mom, when I helped the 257 factory design the fan for half a year, I newly recognized a teacher as a worker or chief engineer of Lanzhou Chemical Factory." Liang Yuan decided to plant things in Chu Huifen’s head first.
"During this period, the sales volume of adjustable fans in Factory 257 has increased greatly, and it should be no problem to exceed one million units this year. On average, each adjustable fan needs about 4 kilograms less abs plastic, and this alone requires 4 tons of abs plastic, while the annual output of abs plastic in Lanzhou Chemical Plant is only 10,000 tons. Earlier, Mr. Chu said that Lanzhou Chemical Plant has already started to prepare for abs expansion, otherwise the annual monotonous fan abs quantity in Lanzhou Chemical Plant may not be enough."
Abs plastic raw materials are derived from petroleum. After ethylene and propylene are separated from petroleum by a large cracking device, abs raw materials are obtained by blending and grafting through a special device.
A large number of heating furnaces are needed in the production process of petrochemical enterprises, and the temperature of heating medium is usually 15-5 degrees, while the exhaust temperature of gas turbine is as high as 55 degrees, which is the ideal heat source for all kinds of heating furnaces. The petroleum cracking process is usually completed under medium and high pressure, so the core of all kinds of ethylene equipment and equipment is the ethylene compressor. The gas turbine can drive all kinds of ethylene and propylene compressors.
Generally speaking, a gas turbine can save petrochemical enterprises three or four million yuan in energy and fuel each year.
"Teacher Chu said that Lanzhou Chemical Plant plans to introduce gas turbines to do power and thermal linkage with the production line of the plant this time. Unfortunately, the foreign asking price is too high, and the price of each unit is about 30,000 yuan. Some Lanzhou Chemical Plants can’t bear the present situation, so they are hanging."
After listening to Liang Yuan’s talk, Li Yuanling straightened up and asked, "Xiaoyuan, does your teacher Chu have any plans for domestic equipment?"
"I don’t know, I always know if mom can produce qualified gas turbines here." Liang Yuan scratched his head, and some koos said that Li Yuanling kept his head down and thought quickly. Although there were many problems in the 99 gas turbine units, the whole project team was not a success. In these years, Li Yuanling accumulated a lot of first-hand data through intermittent experiments. Through long-term study and experiments, he was familiar with the performance of the whole unit, and he knew quite well where the problems and general solutions were.
Li Yuanling seems to be very easy to modify some rash data and replace some parts that have not been scientifically verified. It is easy to achieve 9% power level of the original gas turbine in a short time according to the original design. If one year is rectified, Li Yuanling is confident that the domestic units will reach the original power level. Of course, some core components still need to be imported for the time being.
Looking up, Li Yuanling said hurriedly, "Xiaoyuan, ask your teacher Chu another day if the domestic gas turbine can reduce the cost by about 20 thousand yuan, can they consider changing the domestic equipment?"
Liang Yuan is a little funny when he listens to my mother’s pricing. 99 The cost of that gas turbine set is 10,000 yuan. I set the price at 20,000 yuan nearby. Obviously, I don’t want to take advantage of myself. I plan to sell one and earn one, which is equivalent to borrowing my own money to turn around.
Liang Yuan endured a smile and said, "Teacher Chu will arrive at the stream on Monday, and I will ask her if it is possible to change the domestic equipment, but it is still difficult to connect the gas turbine with the whole production line. I will send the newly dug engineers together."
Li Yuanling looked at Liang Yuan and remembered the motive. The digital control system was funny and said, "Whatever you want, you can do whatever you want with this project."
Rest assured, Liang Yuan and Li Yuanling chatted. Soon after finishing their studies, two girls, Laura 1i, also came to the living room. Two little girls, Haw Zha Zha, talked about these natural trifles around Li Yuanling. Liang Yuan was frightened and listened for fear that Ning Wanfei would accidentally leak out the "menopausal syndrome" that she knew Liang Yuan’s mind. She watched Liang Yuansha wriggle around and waved her white hands proudly. While Li Yuanling was not paying attention, she made a "I won’t say" and Liang Yuan hurriedly gave a dog leg.
Thank you for your support. Your support is our greatest motivation.
Chapter 56 Possibility
Sheng ‘an Railway was built in 1994, with a length of 256 kilometers. It was also the first railway built by the Japanese invaders in China. After the founding of the People’s Republic of China, the double-track construction of Shengjingxi section was completed in 1955 due to the reasons of resisting US aggression and aiding Korea. The eastern section of Xi ‘an was stopped due to the high construction difficulty, and the passenger and freight volume of the national economy increased year by year to the Ministry of Railways. It was not until 1995 that the double-track expansion project of Sheng ‘an Railway was completed. The whole Sheng ‘an Railway traverses the remaining veins of Changbai Mountain, which is the most steep section
Liang Yuan sat in Liang Haiping’s office and chatted over the brief history of Sheng ‘an Railway. I thought it seems that my brother-in-law has made great efforts on the railway. Reading whenever he is close to the railway is much more diligent than his own. When I looked up, there was still an hour when Chu Huifen would take the 27-time express to the stream. I really don’t know how to get along with Chu Huifen’s gas turbine.
Due to the large number of tunnels to pass through, the whole train was lit up for 27 times. Chu Huifen sat quietly and stared out of the window, and from time to time, she swept over the peaks and steep cliffs to go back to the stream. It was night. I didn’t expect this journey to be so steep and used to it. Looking at the mountains and valleys along the way, it was unique.
I never thought that I would return to the Northeast so soon. Chu Huifen’s thoughts returned to work. After returning to Lanzhou from Xixi, I applied for a large-scale project in abs plastics industry. I didn’t expect that the project had just been approved to the factory sales department, so I found the door and looked at the data in my hand. Chu Huifen almost wrote one more in the sales department.
The span from 4 tons to tons is really too big. Lanzhou Chemical Plant is very surprised to see the statistics of the sales department. It is learned through communication that the annual output of 257 factory will exceed 4 tons this year, and the factory leaders finally can’t sit still. If what 257 factory said is true, it means that the abs raw material production capacity of Lanzhou Chemical Plant is likely to be insufficient, which also means that Lanzhou Chemical Plant has been applying for expansion plans and is likely to be approved by the Ministry of Chemical Industry.
It’s a big deal, and it’s a bit confusing. Lanhua decided to let Chu Huifen go to the northeast to find out what the 257 factory is doing. If what the 257 factory said is true, Lanzhou Chemical Plant will have to intensify its activities in order to get an early approval for the expansion project. When the construction cycle of the whole expansion project takes six months, the production capacity will probably not be able to keep up with it if it is too late.
The No.27 train arrived at the brook train on time. Chu Huifen and her colleagues just stepped onto the platform when they heard someone shouting for Teacher Chu.
Looking at Liang Yuan and two men waving at a distance, Chu Huifen smiled and walked past. After greeting Liang Haiping and Zhou Heng, Chu Huifen blamed and asked, "Xiaoyuan, how did you come to Neusoft? There is no class recently?"
Two little girls, Ji, will talk to Chu Huifen every half month, so Chu Huifen knows all about Liang Yuankao’s juvenile class and the transfer of two little girls to Dongda Primary School.
Liang Yuan knew that Lanzhou Chemical Plant was going to expand the production capacity of abs raw materials, and also listened to two girls chatting with Chu Huifen. Chu Huifen said that it was possible to go to Beijing Ministry of Chemical Industry to apply for the expansion of the chemical plant in a few days before she learned the information.
"Teacher Chu, I recently helped the 257 factory to improve a new model of adjustable fan. I came to pick you up all the time for a change." Liang Yuan pulled the 257 factory out as a shield.
Zhou Heng took Chu Huifen’s hand and luggage belt took a few people out of the car from the commuter entrance. Liang Haiping, the old-fashioned Jinbei bread, told Zhou Heng to go to the locomotive factory hostel.
"I didn’t expect that Xiaoyuan entered the juvenile class. When Jiajia and Feifei told me, I was shocked. Now, before the teacher went to Tsinghua to teach for two years, Xiaoyuan can directly take the postgraduate exam at Northwest University. Are you interested?" Chu Huifen smiled and joked.
Liang Yuan shrank his neck and said, "I’ll go to Northwest University if I’m not afraid that I’ll embarrass you, but it’s better if I pass the exam."
Hai-ping Liang also said with a smile, "It’s enough for you to save a shame, but don’t go to the northwest to shame. How can a student like you not study hard and remember the special skills every day?"
A line of people came to Lanzhou Chemical Plant, the guest house of the locomotive factory, laughing and joking. Four people were sent on this trip, including Chu Huifen, just a man and a half. Liang Haiping arranged two adjacent standards to put luggage together with Chu Huifen. Wang Liping, an Lanhua engineer, asked curiously, "Director Liang, is this a foreign-related hotel? When I came in, I saw many foreigners chatting in the bar on the first floor. "
Liang Haiping shook his head and said, "This is the guest house of our factory, which is not so high-level. Foreigners are a project of the GDR expert factory to provide technical support."
"Director Liang’s hostel is really well built, and it’s almost time to catch up with Beiping Hotel," Chu Huifen said with emotion.
"The teacher later settled down here in Xidu, and the teacher just reported my font size directly when checking out. No one dared to accept money," Liang Yuan said triumphantly.
Chu Huifen patted Liang Yuantou in distress situation and said, "Aren’t you afraid of humiliating the teacher?"
A few people simply chatted for a while and watched it getting late. Liang Yuan didn’t say anything about the meeting place and Liang Haiping left the hostel.
The next day, Chu Huifen sent three colleagues to the 257 factory and the city department store to investigate himself and came to the Northeast Locomotive Works. Chu Huifen knew that Liang Hai Pinghe Liangyuan should be clear about the sales data of fans and the details of the 257 factory.
Hai-ping Liang listened to Chu Huifen’s purpose and laughed. He took out a document from his desk and handed it over. He said, "Chu Gong can rest assured if he takes a closer look. This is the sales statistics of fans in September and September."
I originally planned to go back to school to be a good boy. At present, I still don’t want to go back. Let’s wait until Mrs. Fang cools down after a while.
