Lu Siyuan went to Secretary Zheng's house to get the key.
Zheng's expression was a little unnatural. He hesitated and asked, "Siyuan, did Director Lu find an expert to repair the machine?"
Lu Siyuan shook his head, "No, I'll take my teacher to have a look."
Secretary Zheng was a little disappointed, because Director Lu had called him in advance to inform him to give the key to Lu Siyuan, so he handed the key to the young man in front of him.
Su Ye got the key and walked towards the Changyou cooking oil factory, obviously not intending to invite an expert to look at the machine.
Lu Siyuan asked curiously, "Doesn't Teacher Su need to ask Professor Zhou for help?"
Su Ye said casually: "She is old and it is not convenient for her to travel. I will check on her first."
Su Ye walked into the Changyou cooking oil factory. The factory was very large, with a row of large factory buildings built with blue bricks. The walls were painted white with pink paint, and on them were printed large red characters: "Hard work, build the country with diligence and thrift." There was a playground inside the factory for workers to play basketball and table tennis.
This is the most imposing building in this area. It was once so glorious, but now it is gradually becoming desolate.
Su Ye used the key to open the warehouse of the cooking oil factory, where ten large screw oil presses were placed. She carefully checked the peripherals of the machines one by one, and took out a piece of paper and pen from her bag to record some data.
She knocked on the steel panel of the oil press and muttered, "We have to take it apart to find out what's going on."
Lu Siyuan widened his eyes and looked at Su Ye in silence. He walked out of the warehouse and quickly brought back a box of tools, including wrenches, screwdrivers, fall chains, crowbars... and an electric drill.
Su Ye gave him a thumbs up. She found that Lu Siyuan was quite courageous to some extent. If it were someone else, they would definitely stop her regardless of the consequences.
She pointed to the English description on the oil press nameplate and exclaimed, "Your father has good taste! He bought an Anderson machine."
The so-called Anderson oil press, which is the most common screw oil press that Su Ye saw in later generations, has low production efficiency and is used for oil pressing in small family workshops. In the 10th century, it became small and exquisite, and could be operated by one person, but in the 1960s it was a huge machine.
Su Ye spent three hours using all the tools to dismantle it one by one, including the frame, spiral pressing shaft, material barrel, material shaft... He found some problems, such as the pressing bars and pressing rings of the oil press.
She took out a pen and paper and drew the structure of the oil press.
Su Ye took off his gloves and washed his hands. "Lu Siyuan, don't worry. Remember to come to school tomorrow."
Lu Siyuan watched the whole process of her disassembly without blinking his eyes. It was clearly a pile of cold machinery, but his blood was boiling. If he studied hard and studied the principles of the oil press seriously, wouldn't he be able to handle these machines calmly one day
When Su Ye walked out of the factory, the sky had already darkened, and stars were hanging in the sky.
The next day, Su Ye went to the library and borrowed all the books related to oil extraction. China was founded not long ago, and not only was the technology backward, but it was also blocked by the international community, so there were not many books on this technology.
Su Ye enthusiastically sorted out the useful information, filling up a large sheet of paper.
She put down her book and pen, took a walk outside, and carried two fat chickens to Grandma Zhou's house.
Zhou Honghan was very happy to find Su Ye coming to his house. Then he looked at her carrying two chickens and asked with a red face, "What's wrong? Did you pick up chickens again?"
Su Ye nodded, "Yes, I think I will have to ask Grandma Zhou for something later, which is quite brain-intensive. Let's have a meal of chicken first to replenish our body."
Zhou Honghan smiled and said, "Don't be so polite. If you have any questions, just come. I promised you a long time ago."
Zhou Honghan just thought that Su Ye wanted to discuss some exam questions. After all, the graduation exam was approaching, so she had to cram for the exam. In fact, why did she need to go to great lengths to bring a chicken to the door and cook a meal herself for these little things
Seeing Zhou Honghan agreed readily, Su Ye didn't say anything else, but just smiled tactfully: "It won't delay the meal, let's eat first and then work."
She killed one of the chickens with swift and swift movements, and Zhou Honghan was amazed watching from the side.
I don't know what this pheasant ate to make it so fat. After opening its stomach, I took out a piece of yellow chicken fat. Even its intestines were fat and greasy.
They are nothing like the chickens Zhou Honghan raises himself. They are so skinny that even if you kill them, you probably won’t get any fat from them.
Su Ye cut the chicken into two halves, put one half in a casserole, added wolfberry, red dates, yam, and bamboo shoots to make a pot of wild chicken soup. She peeled chestnuts from the other half and fried it in a pan to make a chestnut chicken dish.
Zhou Honghan went to the vegetable patch to peel some pea sprouts, picked two tomatoes, and stir-fried two vegetables.
The pheasant brought by Su Ye was tender and fragrant, chewy and delicious. The chicken was very tender, the thin bones were so crisp that they cracked when bitten, and the fragrance went into the bone marrow.
Zhou Honghan had eaten all kinds of delicious food before, but she had never tasted such a delicious chicken, so delicious that it was even delicious to the bone. If she wasn't an old lady, she would have wanted to gnaw on the bones and suck the delicious taste inside.
But she didn't care why the chicken was so delicious. She just thought it was because she hadn't eaten delicious food for a long time and her stomach was lacking in fat, so everything tasted delicious. She ate the fried chicken with chestnuts until her mouth was full of fat. Then she drank a mouthful of the hot chicken soup, which was fresh, sweet and delicious.
Zhou Honghan was so happy that she was overjoyed. Not to mention one request, it would not be a problem for her to agree to ten of Su Ye's requests.
After eating and drinking, Su Ye wiped his mouth and went to wash the dishes diligently.
She took out a bunch of finished drawings and a large sheet of materials from her bag and handed them to Zhou Honghan. Su Ye said, "I have a student named Lu. His father is the director of the Changyou Cooking Oil Factory."
Although Su Ye had worked in mechanics, he was more of a software designer. As the saying goes, every profession has its own specialties. If foreign technology was so easy to break through, they would not be so generous to sell their machines to China.
Zhou Honghan picked up the drawing that Su Ye handed to him inexplicably and looked at it. The moment he saw the drawing, his eyes suddenly changed.
"You drew this? The oil press?"
Su Ye nodded, "Yes, this is a screw oil press, called the Anderson oil press. When Director Lu bought it, it was already badly damaged, and it was worth 180,000 RMB. It can't be returned, so now we can only try our best to repair it."
Su Ye's words made Zhou Honghan fall into deep thought, and then he looked at the drawings she had drawn.
"These oil presses are worth 180,000 yuan. Were they bought from foreigners? How long will it take the country and the people to earn this 180,000 yuan in foreign exchange?" Zhou Honghan said with concern.
Su Ye didn't expect that she was thinking on another level. People these days are really patriotic and think about the country in everything.
As if there was no need to say anything further, she nodded and said, "Yes, it's not only a waste of money. If these machines are not repaired, many workers at the Changyou Cooking Oil Factory will be laid off."
Zhou Honghan stood up, took out his glasses from the cabinet and put them on, then carefully studied the results of Su Ye's disassembly of the machine yesterday.
"Your drawing is very good. I noticed a little problem. But my old arms and legs have been idle for many years. I can't sit still. Take me to see some machines tomorrow."
Su Ye paused and said, "Grandma Zhou, you must study it carefully. I heard from Director Lu that the oil output of these oil presses is 3% to 5% higher than that of the ones we use domestically. If I understand it and produce it myself, I can save a lot of oil and grain every year."
Although it was an outdated machine discarded by other countries, it was thirty years more advanced than the traditional domestic oil pressing and hydraulic oil pressing technology. Speaking of this, Su Ye couldn't help but feel ashamed.
Zhou Honghan was surprised after hearing Su Ye's words. After a long while, she couldn't help laughing out loud, "You are right. If the machine tool factory can manufacture these oil presses."
The next day, Zhou Honghan and Su Ye went to the Changyou Cooking Oil Factory.
Director Lu flew over from outside overnight. He saw Teacher Su Ye accompanied by a white-haired old man coming to the factory.
"Hello, Professor Zhou, hello, Teacher Su, I will take you to see the machine. Thank you, if it weren't for you, I really don't know what to do with my factory."
He looked at Su Ye with gratitude.
Zhou Honghan went to see the oil press that Su Ye had not finished dismantling yesterday, and personally dismantled the power unit of the oil press. He also asked Director Lu to connect another oil press so that she could see how the machine worked. Director Lu opened the oil press and demonstrated it to Zhou Honghan. The machine neither took in oil nor produced oil.
Zhou Honghan found the cause of the problem and said, "There are problems with both the pressing bar and the pressing ring. Xiao Su, you are really good."
This result was exactly the same as Su Ye's original guess. Zhou Honghan couldn't help but look at her.
Little Su is so powerful? Director Lu was confused. What does this have to do with Teacher Su
Zhou Honghan paused, and said carefully: "Our factory does not have the same model of parts used abroad, so we can't repair them directly. I will draw the design immediately and send it to the machine tool factory to have them produce it. I'm afraid we need to wait for a while. Director Lu, can you wait? If you can't wait, there is another way. Contact the factory where you bought the oil press and ask them to mail the ready-made parts to us."
Director Lu was overjoyed when he heard this. This was the best news he had heard in all those days.
Just repair it, he doesn't have so many requirements!
RMB must be converted into foreign exchange before it can be paid internationally, and there is a fixed quota for foreign exchange every year. Director Lu has already spent all his foreign exchange on buying oil presses. Most of City C's foreign exchange quota this year has been spent on these machines, so he has to wait even if he doesn't want to.
Director Lu said gratefully: "I will hold on for a while. I have already sold my house in Beijing. There is no need to rush to repay the loan I borrowed from the bank."
"We have to trouble Professor Zhou. These parts must be made as soon as possible. If the machine is delayed for one day, the factory will be shut down for one day, which will waste money and food."
Zhou Honghan said: "Director Lu, don't worry. I know this."
After Director Lu sent the two away, his clothes were soaked with sweat. At this moment, he felt like "when you are at the end of your rope, you will find a way out", and his legs were so weak that he could no longer walk.
…
Director Lu had just escorted Professor Zhou out of the Changyou Oil Factory. After they left the factory, Su Ye asked Director Lu about his doubts: "Didn't this batch of oil presses have to be inspected and tested before they were bought? Can oil be squeezed out after putting oil in them?"
Director Lu said: "With such a large amount of foreign exchange, how could I not accept and test it? I personally went to the foreign factory to investigate, and watched with my own eyes as the peanuts were put into the machine and golden oil was squeezed out. I weighed the oil myself."
After Director Lu sent the people away, he went to the oil factory office and met Yu Fuda.
Yu Fuda smiled and said, "Director Lu has been working so hard these days. Can you raise enough money to redeem the factory? I owe so much money, how can I pay it back?"
When the transfer order comes down this year, I will be the deputy director of Changyou Oil Factory. Don't worry, Lao Lu, for the sake of our two years of colleagues, I will definitely take care of your son and sister-in-law for you."
Director Lu was about to promise the workers that the oil press could be repaired and would be put back into service this year, but when he thought of the question Su Ye had just mentioned, he swallowed the words that were on the tip of his tongue.
After the incident, he was still thinking: How come I went to inspect the factory in person, but the machine I bought was broken
Director Lu said coldly: "Don't bother with that. I haven't received a transfer order yet."
The oil factory staff remained silent after hearing this, while the workers' attitudes were volatile.
Everyone discussed privately: "Vice President Yu wants to be the factory director?"
"Although Director Lu is not thorough enough, if this villain were to become the director, the factory would be in turmoil. He is no match for Director Lu!"
