Chapter 213 Lowering Requirements (Second Update)

The next day, Liu Hai arrived at the factory and didn't ask about whether he was studying or not. At noon, he went to the cafeteria to eat, and then Sun Aiguo came to the maintenance department.

"There is a study group coming to the Northeast to learn from our experience in building cars. Xiao Liu, will you participate?" Sun Aiguo asked while watching Liu Hai looking at some data and wandering around the laboratory.

Liu Hai shook his head: "I won't participate. There are too many things here and I can't handle it."

"Well, are you making aluminum alloy?" Sun Aiguo looked at the test materials, picked them up and asked.

"Well, the ship's propeller will be much heavier if cast iron is used. I'll try aluminum alloy. If aluminum alloy works, I will use aluminum alloy engines in the future." Liu Hai nodded and said.

Sun Aiguo also knew this. When he heard this, he said: "Aluminum alloy dissipates heat better. If aluminum alloy can be used, how much steel can be saved in the future."

"Yes, but it's still being tested. The results may not be available for a while."

"This time, we mainly want to learn from the experience of manufacturing diesel engines. The trucks they manufacture have many problems, especially the engines. The failure rate is much higher than ours." Sun Aiguo continued.

Liu Hai raised his head and said while sorting out the data: "Our single-cylinder diesel engine has a low failure rate and has advantages."

"That's the truth. Since you don't want to, forget it. I'm busy and I'll go get ready first." Sun Aiguo nodded when he heard this. The single cylinder has its own advantages.

"By the way, the samples of walking tractors produced by our factory need to be processed now. Do you want them in your village?" Sun Aiguo asked.

Liu Hai asked in confusion: "Samples? Aren't they all sent away?"

"The two units and supporting equipment that were inspected and accepted by the expert group have been returned to us now. We will no longer produce them, right?" Sun Aiguo explained.

Liu Hai nodded and agreed: "Of course this is good, thank you, director."

"No thanks, just find a car and take him away later." Sun Aiguo waved his hand and prepared to leave.

But Liu Hai immediately said: "Director, I think our factory should keep this first walking tractor, and let future generations know the history of our factory after dozens or hundreds of years."

"Oh, what you said is a big loss. No, I'm going to exchange my first motorcycle for it."

"I'll find a way to get you two sets of walking tractors in your village. They're indispensable over there." When Sun Aiguo heard what Liu Hai said, he left.

There is nothing we can do if we come from the Northeast to learn. The first truck was produced there the year before last. Everyone was very excited and excited. According to history, this year the top leaders went there to inspect and the first truck was produced in 23 days. car.

But the good word-of-mouth has gradually changed. At the beginning, everyone saw the four different shapes made by the motorcycle factory and almost laughed out loud. This simple patchwork thing can be better than our trucks.

But how word of mouth comes about is through use. It may seem simple, but they bring a hydraulic dump, which greatly saves the workers' physical strength.

And you dare to run on any bad road, let alone the highway at this time. It is useless if you design a speed of 150 kilometers per hour. On the contrary, this kind of four-dimensional car is the most suitable, and you dare to run on bad roads.

What is the key? It is simple to operate. To drive a car, you must have a driver. Drivers are in short supply. At this time, drivers must be able to repair cars. The truck has a complex structure. The four-wheel truck has a simple structure, and the four-wheel truck has a simple structure and is less likely to break. .

Gradually, many units even replaced trucks with four-cylinder engines. Single cylinders are also more fuel-efficient. Nowadays, there are oil indicators.

Even in some places, it is not like adding a fence, adding some steel bars, pulling seven or eight tons and running around.

Fortunately, our modification capabilities were taken into consideration when Liu Hai was designing, and the hydraulic system had a large margin. Unlike later, if you have to exceed the weight, it depends on whether the cylinder explodes or not.

Just relying on the dump truck, it is very popular, just like when collecting grain, the dump truck arrives at the place, and it is over in half a minute.

The units are also willing, and the self-unloading efficiency is so high. Although no one expresses their disapproval, after all, it is good to have a car, but the demand for the troops has been reduced, which explains the problem.

So they reported it to the ministry, and we also came to learn and prepare to improve the truck design and also engage in self-unloading... Of course the ministry would agree, and it was all the same as the Machinery Department.

After having dinner at Xu Damao's house, Liu Hai spent most of the time in the factory. After the aluminum alloy test was completed, Li Dali and others took the drawings and started manufacturing parts.

Liu Hai also started to go to school. After the motorcycle factory manufactured new boring machines, they successively manufactured lathes, grinders, milling machines, etc. This is where the boring machine technology was used.

The Maintenance Department is now changing its guns. New lathes, grinders, milling machines, etc. are gradually in place. The Maintenance Department is separated from the factory by a wall, as if it is another part. It is different from other workshops in motorcycle factories. Other workshops are full of slogans. You fought for me to grab it.

Each product line also has its own maintenance department. Liu Hai basically doesn't do field work here. There is no way. Those who repair hydraulic presses will definitely not repair diesel engines, right?
On the other side of the laboratory site, a heat treatment workshop is being built. The heat treatment workshop is the core workshop of the motorcycle factory. The wall is higher and it is an important area. However, a door is opened between this important area and the laboratory site, and the wall here is also heightened. Well, an excavator directly dug a large ditch behind the wall, about ten meters wide and several meters deep. This large ditch separated the heat treatment workshop and laboratory from the field and farmland behind, and it was considered a simple defense.

Liu Hai stood on the wall, looking at the ditch, thinking that it would be easier to fish in the future.

"It's a pity that the fishing tackle on my aircraft carrier is top-notch."

The three of Li Dali feel tired, especially when they manufacture parts and bring newcomers. The newcomers don't understand anything, and they are far worse than the three of them before.

But there is no way, this is a task.

Liu Hai's life has become normal. He goes to school at night to study, and lives in the courtyard and the factory. Li Dali and the other two work overtime at night, because Liu Hai can just give him the drawings now, and only ask the section chief unless he doesn't understand.

At the end of March, Liu Hai and Li Dali and three others successfully assembled an aluminum alloy engine. Liu Hai originally planned to design a six-cylinder engine, but during manufacturing, he found that the six-cylinder engine required die-casting parts, so there was no way.

Only the requirements were lowered, and the six-cylinder became a four-cylinder, with only 115 horsepower. But Liu Hai knew that this was enough, because the current mainstream marine propellers are either diesel or two-stroke.

The propeller is made of stainless steel. In 5, Taigang produced the first batch of stainless steel.

The engine uses silicon-aluminum alloy, which contains silicon, magnesium, copper, etc.

It took Liu Hai a month and a half to produce a marine external unit, which is not impressive in this era, because this era is about catching up with Europe and the United States in three years, and a certain automobile factory in Northeast China produced the first domestically produced car in 23 days.

Although Sun Aiguo had known for a long time that Liu Hai was very sure of getting into trouble, but when he saw the four-cylinder aluminum alloy engine whirring, his eyes were like bull's eyes.

"Aluminum alloy!"

"Four cylinders!"

"115 horsepower?" Sun Aiguo still couldn't believe his eyes and ears.

"Director, this is a high-speed gasoline engine. It is different from others. It is different from the car engine. This one just drives this small propeller. This one is made of stainless steel."

"Find a place to try?" Sun Aiguo thought it was better to give it a try.

Liu Hai nodded, and then said: "We are ready here."

Liu Hai welded an iron boat himself, mainly because he was afraid that the wooden boat would not be able to withstand the high speed.

"What kind of place do you want to test?"

"Reservoir, I'm mainly afraid of things in the river." It's not summer yet, and there isn't a lot of water in the river.

"Get ready, I'll find a place." Sun Aiguo thought about it and found a place soon.

Liu Hai thought he was going to some reservoir, but you guessed it, he came to a place called Nanhaizi by people in Kyoto.

"Director, right here?" The tricycle towed a steel-hulled boat of seven or eight meters. Behind the boat was a two-wheeled frame, which was also a special tugboat made by the maintenance department.

"It's here, I reported it." Sun Aiguo nodded.

A few people from the maintenance department put the boat into Nanhaizi, and then directly connected the hanger. Of course, it is not an electric start, but the hand pull is the same.

Sun Aiguo climbed onto the boat and said, "Let's get started."

Liu Hai started the engine. This machine has three gears, reverse, forward, and neutral.

The machine started, Liu Hai directly put it into forward gear, and the iron-hulled boat started to move slowly. After leaving the shore, Liu Hai throttled the gas.

Oh oh oh!
Sun Aiguo hurriedly held the boat and muttered in his heart: "This speed is much faster than crossing the Yangtze River back then. If there had been this back then, the transport captain's cannon would have been useless."

People on the shore were also curious, what kind of boat is this? Is it so fast?
Sun Aiguo looked at Liu Hai, who was operating the machine, and muttered to himself: "Maybe our factory will be able to build ships in the future."

After landing, Liu Hai accidentally said: "If this ship is equipped with four such machines, the speed can exceed one hundred kilometers. If the ship is bigger, then it can be equipped with a few more. Boss Huo, with Ying The sailors just stared."

"Ah, doesn't Daiying have gunboats?"

"100 kilometers is 54 knots. A gunboat with more than 20 knots would be good." Liu Hai said.

Sun Aiguo felt as if he had caught something, but did he catch it?It wasn't until night that Sun Aiguo remembered, what would the captain of the transportation team think if he knew we had a 54-knot ship?
How dare you nag her on the radio?

"Build four first, let's test the speed." The next day, Sun Aiguo found Liu Hai and issued the task.

Liu Hai touched his head, but when he thought about this era, the era of stepping forward, he felt relieved: "Okay."

"Director, I will go back to my hometown during the Qingming Festival in a few days."

"Sure, let's take the hand tractor with us when the time comes." Sun Aiguo nodded.

This year's Qingming Festival is April 4th, and the manufacturing press for the marine outboard motor was given to Li Dali and three others. If there is no plastic on the machine, it will be made of aluminum alloy. It is the same, but it looks better.

The pressure was put on Li Dali and the others, so Liu Hai thought about flatbed trucks, which were necessary for the transfer of excavators. This six-cylinder diesel engine uses cast iron. The reason why the six-cylinder engine was installed was because Liu Hai felt that this engine could be used after the engine was switched on. At most, the electric start of the air conditioner and the like could be modified, and the truck would be gone for decades in one step.

Liu Hai knows that in a few years, there will be no need to study it, and now there is no need to work on the back of the four-cylinder.

On the first day of Tomb Sweeping Day, Liu Hai returned to the village, and there were two other vehicles with him. When the vehicles arrived at the drying yard, the captain had already gathered the young people in the village.

After Sixiang arrived, he began to unload the truck, four walking tractors, and the matching noodle grinder, crusher, arable land, transported things, and several sacks of germinated sweet potatoes.

"Chief Liu, let's go first." The two men were given a chicken by Li Dali and Gou Rong in the village.

"Drive slowly, be careful on the road." Liu Hai said in a greeting.

"okay!"

"This..." The captain looked at the equipment. They were all machines, and there was also a barrel of diesel.

"This is a tractor. Come on, I'll teach you how to do it." Liu Hai rolled up his sleeves and taught these people how to drive a tractor.

The captain watched the walking tractor start, his eyes lit up, and he quickly selected a few young people to learn from him, including some young people who showed Liu Hai the car on the drying ground during the Chinese New Year.

Then Liu Hai showed off the flour grinding, crushing, plowing and other machines. There was no leisure time this day. Wang Hongmei was holding her child and watching the fun.

Liu Hai spent the whole day teaching people how to drive a tractor.

We had dinner at the captain's house in the evening, and the village chief also came. After Liu Hai left, the village chief looked at the captain: "We need two in the village."

"Fuck you." The captain drank some wine. When he heard this, he slapped the table and started to curse.

At this time, rural cadres were all selected from below. The team leader was at the village headquarters. It was common for the village chief to point at the township cadres and curse them in the countryside. Of course, he had some sense of the truth.

"You are a donkey asking for goods. You are not as sensible as a child. Guess why I gave you four." The village chief also slapped the table and cursed.

When the captain heard this, he said impatiently: "You can take care of me, this belongs to our team."

"Huh, where's the diesel? You can't go to Comrade Liu Hai for diesel anymore." The village chief took care of it directly.

"There are still spare parts, who will repair them if they are broken?"

"You are a donkey begging for goods and even cursing, but the machine is giving you fuel. What do the other captains think? Why does your team have so much fuel?"

The captain gritted his teeth and said, "One."

"Damn it, I didn't ask you to have three machines. Just two. In addition, several farms next door will come to process the grain and the price will be lower."

"Village chief, you mean we can process it externally?"

"Otherwise, why don't we send it to the village grain station for processing?" the village chief asked angrily.

"Okay, okay, just two."

"You are so lucky. There is a talented person in the team. Do you know how much these four machines are worth... There is no plan for this number." The village chief raised his hand and made two gestures repeatedly. Down.

"Ah, this, so many?"

"You're a donkey looking for goods. Do you know what to do?"

"Know, know."

Wang Hongmei came in the evening, and the farewell was better than the wedding. She had been holding it in for too long, but Wang Hongmei was not Liu Hai's opponent after all.

Liu Hai put his arms around Wang Hongmei, and didn't think about anything in his mind. It was like this when he returned to his hometown.

"You're just like a donkey. How can your partner endure it in the future?" Wang Hongmei said angrily after her breath became evener. She seemed like she couldn't breathe just now.

Liu Hai smiled: "Isn't it you?"

“People say that’s all that happens after you give birth to a child.”

"Bah, bah, bah, are you thinking about it again?"

"I'm not coming anymore, take a rest." Wang Hongmei said quickly.

Liu Hai whispered: "Don't put too many things on my side, be careful of being stolen."

"Yes, I know." Wang Hongmei nodded.

The next day Wang Hongmei left in the morning, and the team leader came after a while.

"Uncle, these bags of sweet potatoes have all sprouted. They were planted behind our factory last year. The yield is not bad. You can plant them on some wasteland. In the second half of the year, you can use a crusher to make vermicelli and sell them to the factory. "Liu Hai couldn't say anything about the lack of food soon, so he had to say this.

"Okay, okay." The captain's eyes lit up, vermicelli, this is in short supply.

Liu Hai went to visit the graves of his adoptive parents. In his memory, the two old people were also poor people. After all, they came from the war years.

Today, we installed the crusher and flour grinder in place and taught a few people to use them. As for the two walking tractors and equipment missing, you don't need to think about it to know that the superiors have taken them away.

The team leader asked people to put the sprouted sweet potatoes into the ground. When the sweet potato vines grow, they can be cut and transplanted. All the slopes were cleared to carry the sweet potatoes. They were dug first and the grass roots were cleaned. Then they were dug again before transplanting. , clean up grass roots and so on, and use farmyard manure by the way.

Last year, the village grew cabbage and raised a lot of pigs. After all, the cabbage leaves were wasted. After drying, they could be cooked and eaten by the pigs in winter.

The next day, Liu Hai drove away in his car. Wang Hongmei was arranged by the team leader to go to the processing workshop, which is where other villages came to process the food. They had to pay for it. In the past, they had to walk a distance to the grain station in the countryside for processing.

Another advantage of the captain's arrangement is that if the machine has a serious problem in the future, it will be easier to talk to Liu Hai...

Liu Hai drove the car, looked at the words painted on the wall, and shook his head. It was so easy for the United States to be overtaken. During World War II, there were 166 aircraft carriers. Of course, some of them were converted from cargo ships, but it was terrible. Steel plants polluted The aquatic life in the Great Lakes area has become extinct, so our freshwater fish have to be introduced. When the ecology improves later, these fish will be hunted and killed.

Agriculture and industry passed by without a few words.

"Xiao Liu, your teacher called you and said that the sweet potatoes that were taken away from here last year were high-yield. Although they are not very delicious, the yield is quite high, and they are good to use as feed." Liu Hai went to the factory and gave it to the factory manager first. After reporting and canceling the holiday, Sun Aiguo mentioned another thing.

"This is a good thing." Liu Hai originally planned to plant corn, but then he thought, forget it, corn is not as good as potatoes and sweet potatoes.

"Yes, I participated in digging sweet potatoes and potatoes last year. I didn't expect that the ones selected were actually good varieties. But I remember that sweet potatoes are delicious. Why did your teacher say they are not delicious?" Sun Aiguo asked suspiciously again road.

Liu Hai thought for a while and said: "There is a lot of rain in the south, just like when we grow watermelons, it won't be sweet if it rains a lot."

"That's the reason. Are you still planting in the maintenance department?"

"Well, let's just plant potatoes. We can also plant the ones that belong to our factory later, otherwise it would be a pity if they were left uncultivated." Liu Hai nodded.

"Yeah, that's the truth. I'll let the excavator level it out, and your flatbed truck will refuel and dry it, otherwise it will be inconvenient for the excavator to go to other places."

"Director, hurry up and repair the factory."

"This is..."

　By the way, why do people always peek at my outline?
