Courtyard light

Chapter 234 So fast? (First update)
Liu Hai followed Sun Aiguo to the ministry. There was a brand new car parked in the courtyard of the ministry, and the driver was wiping the car with a towel.

Liu Hai murmured in his heart, it's such a winter.

When I arrived at the leader's office, I took off my coat as soon as I entered. Because there was a heater, the leader saw Liu Hai coming and quickly greeted him affectionately: "Comrade Xiao Liu is here."

"Leader." Liu Hai also greeted.

The secretary quickly came in to pour tea for Liu Hai and Sun Aiguo, then went out and closed the door.

Sun Aiguo then said: "Leader, we are here for the oil equipment this time, Xiao Liu, please tell me."

"Leader, the oil pumping equipment is not complicated, but it depends on the depth of the oil well, the working environment, such as the temperature difference, etc., to design the oil pumping equipment, as well as the viscosity of the oil, etc." Liu Hai sat upright. , said.

“I won’t talk about artesian wells, but the Christmas trees can handle it. They are various valves to adjust pressure, flow rate, etc.”

"But most of what is needed is oil pumping equipment, beam pumping units, which are somewhat similar to the principle of our manual water pressure wells."

When the leader heard this, he asked the secretary to get the information, and then asked: "Is it difficult?"

"Yes, the motor drives the oil pumping unit. In one working cycle, there are two power generation states. That is, when the pump pressure is very high, it will drive the motor to generate electricity." Liu Hai took out a drawing and pointed it out to The leader explained.

When the leader saw it, he understood and asked, "Is there any solution?"

"The only solution now is to increase the electrolytic capacitance on the DC side of the frequency converter and reduce it..." Liu Hai said.

The leader finds that he doesn’t seem to understand this?
Well, it’s okay if you don’t understand. At this time, the secretary also came and brought detailed information about the oil field, and then said to Liu Hai: “Can you take a look?”

I opened my bangs and took a look, and it turned out that they were really big, qing, oily, deep and so on.

"Leader, I understand. Let's go back and give it a try?" Liu Hai asked.

"Ah."

"Those two leaders, I will go back and study them first." After reading, Liu Hai returned the information to the leaders, then stood up and said.

"Sit for a while longer. Although everyone is in the capital, you don't come to us often." The leader of the First Machinery Department said as Liu Hai was about to leave.

Liu Hai shook his head and said: "Boss, you are also a busy person, so I won't take up your time. I will go back to study first and come up with a design plan as soon as possible."

"Okay, I'll ask the driver to send you off." The leader nodded and said.

"No, no, let the factory manager take the car later. I'll drive a tricycle back." Liu Hai doesn't dare to take a car. There is only one car in the country. Who is sitting inconspicuously?
Looking at Liu Hai's leaving figure, the leader of the First Machinery Department said: "Xiao Liu is still sensible, but the other people are not sensible at all. Some people come here to report work, and they want to send a car to take them away from the department."

Sun Aiguo chuckled: "Our department is famous, so I am very happy to be able to ride on this car. Maybe I have no other thoughts."

The leader of the First Machinery Department shook his head: "Do you believe what you say?"

"How is the production efficiency after renovating the workshop in your factory?" The leader of the First Machinery Department then asked Sun Aiguo.

Sun Aiguo picked up the leader's cigarette and gave him one. He took one for himself and lit it for the leader. Then he lit it himself and took a nice puff: "Work efficiency has been greatly improved, production has increased, and many workers If you only make one product, your proficiency will become higher and higher. It is estimated that in two months, the production capacity can increase by 50%, and now recruiting new workers into the factory does not require long learning. It only takes a week to learn, and it is just a good product. The rates may not be that high to begin with.”

"And handing some things, such as screws, to supporting factories also frees up a lot of our manpower."

"That's good, but only your factory can do this. Your factory's equipment is the same. It won't work if you switch to another factory." The leader of the First Machinery Department was relieved when he heard that the production capacity could be increased by 50%.

"If the production capacity increases by 50%, we will prepare to import a batch of grain from abroad." The leader of the First Machinery Department said again.

"Is it so serious? Does the country still need to import food?" Sun Aiguo was a little confused. Is the situation in the country already serious enough?
"Don't mention it. You don't know the current situation in the countryside. You eat too much. When food comes out, you eat three meals a day. When it doesn't, you just eat wild vegetables. There is no plan."

"Boss Huo from Hong Kong Island has a large amount of cheap food." The leader of the First Machinery Department explained again.

Sun Aiguo asked in confusion: "Is cheap food cheaper than what we export?"

"It's much cheaper than what we export. Some officials from the former British colony...ahem." The leader of the First Machinery Department nodded and stopped talking.

When Sun Aiguo heard this, he basically understood... At worst, there would be a fire.

Sun Aiguo asked again: "If we are not good at petroleum equipment, which country are we going to import?"

"It's hard to say. Let's see which country has good design and high cost performance." The leader of the First Machinery Department took a puff of cigarette and said that now that he has money, it depends on which country offers the best cost performance and so on.

"But I have confidence in Comrade Liu Hai. You can see that the pictures have been drawn, and there is probably no problem. After you go back, ask Comrade Liu to build the equipment, and then take it over there and test it directly. Let the data speak for itself. Whether it is successful or not. Let’s talk.” The leader of the First Machinery Department directly issued an order to Sun Aiguo.

"That's no problem." Sun Aiguo nodded and said.

"How is things going with Mr. Liu?" The leader took a sip of tea and then asked.

"There is no problem with the Lou family. The key is that Old Lou is not in Kyoto."

"You also know that Old Lou still has some old ideas and wants to meet Comrade Xiao Liu in person. In addition, our secretary has been very busy recently, so we simply wait until after the New Year when Old Lou comes back to report on his work." Sun Aiguo explained. road.

"That's okay." The leader felt relieved after hearing this.

Besides, after Liu Hai rode his tricycle back to the factory, he returned to the maintenance department and started drawing.

"It's a pity that the natural gas was wasted." Liu Hai looked at the design drawing and realized that the natural gas was wasted at this time.

"Building a natural gas power plant next year? Does that require a high natural gas pressure pump? That's a big problem!"

The distance between the kowtow machines depends on the wellhead. Several kowtow machines can share an oil storage system.Of course, Liu Hai Design can only design a single kowtow machine system. You have to wait for the test to be completed before you can connect it in parallel or other systems.

The next day, Sun Aiguo walked over to Liu Hai and asked, "Xiao Liu, how long will it take for the oil production equipment? I'll ask the equipment department to wait."

"It can be completed in the afternoon. In fact, it's not that complicated." Liu Hai's words are true. With the current technical level of motorcycle factories, it is really not complicated to make this. The motor system and oil pumping system are not big problems.

Sun Aiguo was a little surprised when he heard this: "So fast?"

"Boss, I have been preparing here. I just said that I would change it after getting the oil well parameters. You don't think I have been on vacation for the past half month, do you?" Liu Hai said.

"That's good, that's good. The news came back from Hong Kong Island that 50 cars have been booked, but our workshop hasn't been built yet, and I think the exported cars need the kind of standardized parts you mentioned. , This will facilitate future maintenance." Sun Aiguo said.

"And the mainland only gives him a limit of 50 vehicles. If there are more, we will not accept it. The main reason is that the workshop has not been completed yet and it is winter again."

Liu Hai nodded, the Commonwealth is basically a right-hand drive vehicle.

Sun Aiguo said at this time: "There are still some difficulties on the stamping machine, especially some of the covering parts of the stamping car."

Liu Hai knew what Sun Aiguo was talking about, which was a stamping machine for manufacturing curved steel plates. This stamping machine required not only high tonnage, but also high precision. It could not assemble the car to see how big the gap was.

Moreover, manual production is obviously not suitable for batch manufacturing. The speed of manual manufacturing is too slow. The ones for leaders can be manufactured by hand. However, although it is not a loss if normal commercial products are manufactured by hand, the production volume is definitely not high. This It’s the huge gap between experimental products and mass production.

Although there is no way to stamp the entire vehicle now, the larger the stamped parts, the better the results will be.

Just like the car doors, they must be stamped in place at one time. It is impossible to stamp two or three pieces and weld them. The accuracy of the manufacturing is impossible to see. Maybe some doors may have big gaps when they are closed.

"Director, do we have to use stupid methods?" The key to manufacturing high-tonnage stamping machines, especially large-scale stamping machines, is the manufacturing of stamping modules, hydraulic column strokes, hydraulic pumps, etc.

Stamping modules have to withstand repeated strength, so large-scale forging machines are generally used to manufacture them after repeated forging.

In addition, the mold is the same, because for large stamping parts, when stamping, the stress on each mold part is different. If the strength of the mold is not reached, it may cause damage to the mold, poor accuracy, and may cause the stamping parts to directly Unqualified.

Let's put it this way, the larger the cover, the more things are involved, including the stroke speed of the hydraulic column, the pressure of the hydraulic column, the distribution of the motor, etc.

"What stupid way?" Sun Aiguo asked after hearing this.

"Stacking materials means adding precious metals to the materials to make the materials have higher strength and toughness." Liu Hai said.

In fact, the work of stacking materials exists in any field. Just like the earliest gold fingers of chips, they were really gold. And those earliest chips can be sold for a good price even in modern times because of their materials. good.

"You can give this a try. We have no shortage of materials." Sun Aiguo nodded after hearing this. This is also a direction.

"How long will it take to complete the oil production equipment? Then we will directly produce the parts and try them over there?" Sun Aiguo asked again.

Sun Aiguo already wants to hand over the high-tonnage stamping machine to Liu Hai, because Liu Hai is more proficient in this. Others in the factory are full of questions and don't know where to start.

"This production is not very complicated, it only takes a week, mainly just a few jars." Liu Hai said.

"Don't worry about this. The Nanhua Chemical Plant can already manufacture it. After you complete the design, I will send it to the ministry." After Sun Aiguo finished speaking, he saw Liu Hai taking out a few drawings and handing them to him.

"Factory director, this is it. You go quickly. I will hand over the rest of the drawings to the equipment department one after another and try to complete them within a week." Liu Hai handed the drawings to Sun Aiguo and then said.

Sun Aiguo had no choice but to rush to the department. The department was also stunned by the efficiency of the motorcycle factory. They just came to see the parameters yesterday, and brought the drawings today, and it was completed within a week.

The department sent a special person overnight to send the drawings to Nanhua Plant, so that Nanhua Plant could produce them as soon as possible.

Nanhua Chemical Plant started manufacturing pressure vessels in 53, and successfully manufactured them with the full assistance of all parties, so the level of process technology is no problem. If all parts of the oil production equipment are made in China this time, then for The development of my country's oil production industry has a huge role in promoting it.

At least you don't have to look at other people's faces to do things.

Liu Hai handed over the drawings to the Equipment Department one after another, and the rest was waiting for the parts from the Equipment Department.

Liu Hai was not idle either, designing the overall hydraulic system of a 3000-ton large stamping press.

A 500-ton stamping machine for car doors is enough, but Liu Hai feels that a 3000-ton stamping machine should also be used.

To put it bluntly, the biggest technical difficulty of large stamping machines is to make the force on the hydraulic column uniform. After all, when stamping, some parts come into contact with the parts first, and this part will be stressed first, and the other parts that are not in contact will not be affected. force.

This has strict requirements for the entire stamping die and stamping module, as well as the hydraulic stroke speed.

Of course, Liu Hai is still thinking about the crude oil booster pump, which is necessary for crude oil pipeline transportation. Of course, there is no need to build any large-scale, ultra-long-distance gear pumps for the time being.

Oil transportation equipment is also a niche field in later generations, because one piece of this equipment can be used for many years. In later generations, the country of Iran has basically realized oil production, and the oil transportation equipment is manufactured by itself, and the technical content is not low.

Liu Hai's drawings were given to the Equipment Department, which gave them to various workshops and steel rolling mills. For urgent tasks, the steel rolling mills worked overtime overnight to produce them.

No matter what process and manufacturing methods are adopted, the first kowtow machine must be guaranteed for 100 years... ahem.

The motor production workshop of the motorcycle factory was manufacturing molds overnight, and the Nanhua Plant also started work overnight after receiving the task.

In less than a week, all parts and components were complete. Sun Aiguo, the leader of the First Machinery Department, Liu Hai, and several workers took the train to the test site. The cans from the Nanhua Plant were shipped, but it was still difficult to get there. I need to go to the site to see what infrastructure is being built.

This is a special train, which shows how seriously the superiors attach great importance to this mission. Liu Hai also saw someone with a gun. After all, the leader of this train.
