Chapter 119 A huge breakthrough in recovery technology
"The research is complete, all that's left is large-scale practical testing?"
This was no small matter, so Qu Mingli confirmed it again and again before reporting it to the province.
The people in the province didn't understand either, so they asked the chief engineer of the provincial tractor, who just frowned.
"What's wrong? Unreliable?" The man from the province asked hurriedly when he saw his face.
The provincial chief engineer wanted to say that this was a bit nonsense. If this thing was so easy to research, it would have been developed long ago and there would be no need to stop it by the higher-ups.
Not to mention that they are just a small machinery factory, where did they get the funds? The Blue and White Porcelain Research Institute had funds and talents, but didn’t they also fail to figure out the research?
The chief engineer was very suspicious that the other party had made some changes to the previous hydrostatic system and claimed that it was his own research.
But since they had already come to him, he still asked, "Do you have a detailed paper or report?"
"Yes." When Qu Mingli reported to his superiors, he sent the report, but people in the province couldn't understand it either.
He handed over the thick stack of handwritten manuscripts. The chief engineer took it and saw the beautiful handwriting at first glance.
In this day and age, people believe that handwriting reflects a person's character. Just looking at the handwriting, the chief engineer became more patient and took the book in his hand and opened it.
But it's just a little more. He is responsible for the technical coordination of the entire factory and is very busy. He doesn't have that much time to waste, so he can just look for the design drawings.
If something is unreliable or there are not many changes, you can tell by taking a look at the design drawings, and you can choose not to look at the rest.
He soon turned it over and took a look at it, then was obviously stunned. He took a second look, and this time his eyes stopped directly on it.
It is very different from the one made by the Blue and White Porcelain Research Institute before. Apart from the main components, there is basically no similarity between them.
The control valve had also been streamlined a lot, and there were even a few components he had never seen before. Compared to his lack of knowledge, it seemed like a new design.
This is quite surprising. The machinery factory in Changshan County is not too small, but it should not have such R&D capabilities.
The chief engineer didn't care about the overall situation. He flipped through it first and found an introduction to a new component. Upon closer inspection, he found that it was indeed his own design.
Moreover, from the original intention to the design principle, it does seem to make sense, and the design is even ingenious.
This made the chief engineer raise his eyebrows a little, and his interest grew. He looked at several components he had never seen before and finally turned to the beginning of the paper.
This time he didn't think about anything and immediately started reading, leaving the man from the province aside. He waited and waited, but after waiting for most of the day he still didn't finish reading.
Mainly, as he was reading, he would stop and look thoughtful, and the time he spent thinking was even longer than the time he spent flipping through the pages.
But he called back after just two glances. Apparently, there was indeed something there that the provincial official didn't understand. Seeing that he couldn't finish reading it in a short time, he just went about his own business.
After a long while, the chief engineer finally turned the last page and closed the paper. "Is this really submitted by Changshan County Machinery Factory?"
The level difference is too big. It is simply not something a small county machinery factory can achieve. Even the senior engineers in their factory may not be able to do it.
Their factory has already reached the top level in the country in this regard, and its R&D capabilities are not inferior to those of some universities and research institutes.
Even if you haven't seen the real thing and can't be sure whether it is feasible, the knowledge reserves and clear ideas revealed here are not something that ordinary engineers can have.
But the man from the province stopped his work and actually gave him a positive answer, saying that this was indeed submitted by the Changshan County Machinery Factory.
The chief engineer frowned and tried to recall for a long time, but he couldn't remember who was demoted to Changshan Machinery Factory for any special reason.
And the question remains: where is the funding? Where does the government get the money to do all this when even a system upgrade requires funding from the province?
The chief engineer was really confused, but he still said to the provincial official, "It seems feasible in theory, but whether it will work or not depends on the actual product."
If it were in the past, he would definitely not be in charge of this matter, as the provincial Science and Technology Committee would naturally be responsible for it.
But the Science and Technology Committee was abolished in 1970 and has not been restored yet. He thought about it and said, "I'll organize a few people to go and take a look."
It has already come to him, and he has read the report. He really wants to know whether this is feasible or not.
Moreover, the main features of hydrostatics are low energy consumption and high flexibility, making them very suitable for tractors. Their factory actually produced a batch of them before.
It's just that there are not many of them, and they are still in the trial stage. Agricultural tractors do not need to operate in low temperatures, so there was no accident like the Jimu 50.
He went back and told the factory about this matter, and specifically asked for the engineer who had been to Changshan before, "Xiao Xie, you are in charge of the hydraulic system, come with me."
A total of three people were called to form an inspection team, including a tractor driver from their factory who was specifically responsible for test driving tractors.
In Changshan County, Qu Mingli received the news and invited Master Tang, who had been invited from another city to modify the system, to come over for testing together.
Changshan Machinery Factory has limited R&D capabilities and has always focused on the production of fixed accessories. Where did it get so many senior engineers and deputy senior engineers?
As soon as they heard that someone was coming, the entire factory took action. Several leaders even put other things aside and focused on receiving the inspection team.
In comparison, Qi Fang, the person involved, was the calmest. He was only in a trance for a long time while hugging Yan Xue the night before the inspection team arrived.
Yan Xue knew what he was thinking, but she didn't say anything. The two of them leaned against each other quietly. The next day, Qi Fang packed up and went to work.
As soon as they got their hands on the things, the two tractor drivers noticed the difference, especially Master Tang who was used to driving the old logging 50.
This new skidder 50 modified by Qi Fang obviously starts faster and is quieter than the old skidder 50.
Worried that the comparison wasn't accurate enough, the veteran tractor driver from Changshan Benxian also showed up and was a bit surprised when he saw it. "The start was much faster."
It is also a static hydraulic system, but the original batch did not have this effect. Just based on this point, Qi Fang's is obviously better than the original one.
Moreover, the county has tested this machine for a while and found that it is not intolerant to low temperatures. At least its stability is acceptable.
Several engineers reviewed the report and learned more: "Reducing the number of control valves will reduce energy loss during transmission."
"It stands to reason that a closed circuit should react faster than an open circuit, but the previous one didn't work that way."
"The machine seems to be more flexible than before," someone asked the old tractor driver in Changshan County, "wasn't the Jidder 50 so flexible before?"
"No." The old tractor driver answered very honestly. Master Tang, who was trying to drive the car, felt it even more obviously and even felt a little uncomfortable.
It is obviously an old machine that has been used for seven or eight years and many parts are worn, but it is more sensitive than a new machine when used.
Sometimes, based on his experience, he felt that he needed to increase the pressure a little, but the machine went through it easily, which made him feel that he could not control it as well as before.
However, this is mainly due to the lack of adaptation. Once you get used to driving it, the efficiency will definitely be higher than before.
The traction has also been improved. When towing another machine, it can be clearly felt that it is easier than before.
When Master Tang got off the tractor, his expression was quite complicated, and he especially glanced at the young man standing quietly on the side.
He was very surprised when he used hydrostatic accessories to convert to hydraulic last time. He didn't expect that the performance could be improved so much this time without any modification.
The provincial towing specialist was a tester, so he not only gave a feeling but also reported relatively accurate data: "The performance has indeed improved a lot."
This is very exciting. Domestic technology in engineering machinery has been stagnant for many years, and the biggest breakthrough is just to increase horsepower.
However, increasing horsepower cannot solve all problems and will increase energy consumption. Therefore, Songtuo, which produces the 50 skidder, developed the 80-horsepower skidder 80 in 1968, but it has never been put into production.
Qi Fang's hydrostatic system is different. It greatly improves performance while maintaining the same horsepower, which is definitely a huge technological breakthrough.
After everyone looked at the test, they immediately held a discussion meeting in the machinery factory and asked Qi Fang about some of the things they didn't understand.
Qi Fang answered fluently without even glancing at the information. It was obvious that all the complex theories and precise data were stored in his mind.
Several engineers from the provincial tow station nodded as they listened, and some even took notes. However, the people from the machinery factory had a hard time listening, and they simply couldn't understand a lot of things.
When the meeting was over, Master Hong couldn't help but sigh to others: "I really need to read more and learn more. His brain is really quick."
Only those who know nothing are shouting that studying is useless. Shouldn't those who are engaged in technology learn more?
The engineers from the provincial tow bureau were also unable to calm down for a while after the meeting, especially Engineer Xie who specialized in hydraulic systems.
This project has been stalled for many years. I never thought that it would be successfully developed one day. And it was not developed by any research institute, but by a small engineer in a machinery factory.
And something that was once criticized as useless can actually improve performance so much. How can it be useless? It is clearly very useful.
The chief engineer of the provincial tractor haulage company pondered for a moment, "This requires large-scale practical testing. I'm afraid your county doesn't have the conditions. Why don't you lend someone to our provincial tractor haulage company?"
After all, the machinery factory only has the ability to produce spare parts, unlike the provincial tractor factory, which can produce tens of thousands of tractors every year.
If the subsequent tests are fine, it will be a good thing for the province. He can apply to the factory to allocate some manpower and funds to do it.
Not to mention that Qi Fang had developed the product all by himself, and the machinery factory had no involvement at all. Even if they had participated, they really couldn't support the subsequent testing, so naturally there was no objection, and soon the notice of Qi Fang's transfer to the provincial haulage was passed down.
Qi Fang went back and said to Yan Xue, "It may take me a long time to come back this time." After all, the provincial capital is quite far from Changshan, and it takes more than a day to go back and forth.
Yan Xue just narrowed her eyes and said, "Then aren't you one step closer to clearing your teacher's name?" After hearing Qi Fang hug her, she didn't say anything for a long time.
Although Qi Fang didn't know, even if he did nothing, Su Changqing would still be rehabilitated in a few years.
But he was just an inconspicuous one in the huge list of rehabilitation, but his case was still overturned with a serious attitude. He must want the latter more.
Yan Xue leaned her head on Qi Fang's arms and said, "Go ahead. I'll be waiting for you at home, waiting for good news from you and the teacher."
The next day, Qi Fang took a train to the provincial capital. As soon as he arrived at the provincial capital, he immediately started working without stopping.
The first step is to adjust the accessories and design a hydrostatic system specifically for tractors that save towing, followed by a lot of practice.
In June, we optimized the matching between the engine and the hydraulic pump for the first time, reducing fuel consumption by 15%.
The second optimization was carried out in July, reducing fuel consumption by 18%, and fine-tuning was performed on some accessories.
It was not until August that Qi Fang finally took a few days off to go home. As soon as he entered the door, he saw Yan Xue and Yan Jigang carrying things out.
He was surprised, and Yan Jigang felt a little embarrassed. "My sister found me a job teaching English at the Chengshui Forestry Bureau Middle School."
Yan Jigang graduated from high school this year. Qi Fang also remembered him and wanted to come back to ask about this matter, but he didn't expect Yan Xue to act so quickly and had already found someone.
"Congratulations." He said to his brother-in-law first, then thought about it and went back to the house to put down his things, "I'll go see it off too."
Renhe went out with the siblings and handed a pen to Yan Jigang, "I bought it for you in the provincial capital."
Yan Jigang knew it was different from the one he usually used, which cost a little over one yuan. His face flushed a little, "Is it very expensive?"
The fountain pen is one of the better models of Hero brand, costing more than ten yuan each, which is really not cheap considering the salary level of that era.
Qi Fang bought it specifically for Yan Jigang. "Here, take it. You're working now, so you could use something better."
Yan Jigang thanked them and took it. He walked to the long-distance bus station and persuaded them to go back. "I can do it myself. Sister and brother-in-law, you don't have to send me off."
The boy, who was only eighteen years old, acted like an adult. He looked at Yan Xue as if he wanted to say something, but when he looked at Qi Fang, he swallowed it back.
Qi Fang thought it was just a private conversation between the two siblings and did not ask any more questions. He waited until his brother-in-law got on the long-distance bus and watched the car drive away before he went back with Yan Xue.
The second old lady was packing things in the main room. When she saw the two of them come in, she said, "There's only one piece of fermented bean curd left. You two stay home while I go out and buy some."
The man was about to go out, but Qi Fang took the can and said, "I'll go, grandma, you take a rest."
The old lady had bound feet, which made it difficult for her to get things done, so usually he and Yan Xue went out to buy things. They didn't usually eat fermented bean curd at home.
Qi Fang always felt that something was wrong, but he couldn't quite put his finger on it. When he returned after buying things, he ran into Qi Yanyu who had just returned from playing outside. He saw him making a fuss.
It was not until after dinner that he had time to talk to Yan Xue alone, seeing that Yan Xue, who usually didn't like fermented bean curd, ate one and a half pieces in one go with dry food.
Just as he was about to hug him, Yan Xue stopped him with her hand. She kept a certain distance from him and said, "Be gentle."
Qi Fang didn't understand at first, and frowned subconsciously when he heard it, "Are you feeling unwell?"
Yan Xue glanced at him and said, "A little bit indeed." He was about to ask when she continued, "I am pregnant again."
Qi Fang paused, and judging by his expression, he must have taken some time to process the situation. Then his handsome face froze.
Yan Xue looked at him and immediately raised her eyebrows, "What? Are you unhappy?"
Qi Fang didn't say anything, which made Yan Xue's voice slightly higher. "Are you really unhappy?"
"Not really." Qi Fang hurried to comfort her, but he didn't know how to describe his current mood. After a while, he asked, "How many months?"
"It's been just over three months." Yan Xue said, "I was planning to tell you in person, so I didn't tell you in the letter."
She didn't expect that Yan Yu was already eight years old and she was pregnant again, even though she and Qi Fang had taken precautions.
It was not until she discovered that her period was half a month late that she went to check, and sure enough, one of the small umbrellas could not bear the weight and died heroically.
This made her very helpless. The college entrance examination would be resumed at the end of the year, and she would have to take the exam with a big belly. She didn't know whether the school would refuse to let pregnant women in.
Her two sons would also choose the time, one would follow her for thousands of miles to chase his father, and the other would follow her to the examination hall.
But now that she had everything, it was impossible to put it back, so Yan Xue just regarded it as another gift from God.
But looking at Qi Fang's expression, it was clear that he didn't think so. Yan Xue stared at him and asked again, "You don't want it, do you?"
This time, Qi Fang paused again before raising his hand and carefully holding her shoulders. "I didn't intend for you to have another child."
It was enough for her to go through all those hardships once; he didn't want to experience that feeling of being anxious and powerless outside a second time.
But since she was already pregnant, he couldn't stop her from giving birth. Qi Fang touched Yan Xue's belly and said, "Don't delay it. I will find a way as soon as possible."
Then he frowned and said, "The quality of the condoms is a bit poor. I have to write a letter to their factory and ask them to improve it." Yan Xue laughed at what she heard.
It seems that Wu Xingde will not be able to jump around for much longer. This widower king in the original book has no target for revenge, so he won't really care about the condom production business, right?
It is not known whether Qi Fang will care about the condom production business in the future, but before that, he first cared about the local medical industry.
I don't know which hospitals he inquired about, but he came back and told Yan Xue that there was a doctor in the municipal hospital who could perform a cesarean section. He had been sent down to support rural medical care and only came back two years ago.
This is also the reason why Yan Xue did not choose to give birth in the hospital. One reason is that it is indeed far away, and the other is that all the qualified doctors have been transferred down, leaving only some young people and inexperienced midwives who are reliable.
It was not until the year before last, in 1975, that the policy was relaxed, allowing some doctors to return to the city through examinations and other means.
The fact that there are doctors in Jiangcheng who can perform cesarean sections undoubtedly gave Yan Xue and Qi Fang some peace of mind, as at least some of the risks had been resolved.
Of course, Yan Xue had asked about this before, but Qi Fang was worried about her, so she pretended that she had never asked.
The vacation was too short, so Qi Fang came back to receive a bomb and asked around for hospitals, and then he had to go back to the province to continue his work.
But in fact, all the improvements that can be made have been made, and the data has been basically collected, so it can be reported.
So the provincial trolls approached him and said, "The higher-ups have decided to reinstate the Science and Technology Committee and hold a science conference next spring. Your project is of great significance, and we'd like to submit it. Please go back and sort it out and write a new report."
The higher-ups still attach great importance to the development of science and technology. As soon as the situation stabilized, they began to prepare for a scientific conference.
Qi Fang said nothing more. He went back to sort out the data and wrote a new report. In the researcher column, the first name was Su Changqing. The procrastinator didn't notice at first and flipped to the first page, then turned back and asked, "Did you make a mistake in writing the project leader?"
"It's not written wrong." Qi Fang's voice was calm, his eyes were burning. He had been waiting for this sentence for too long.
He said: "This project was originally done by my teacher Su Changqing. I just improved on his basis."
