Liu Hai followed Sun Aiguo to the ministry, where a brand-new car was parked in the yard, and the driver was wiping the car with a towel.

Liu Hai muttered in his heart, this winter.

When I came to the leader's office, I took off my coat first when I entered the door, because there was heating, the leader saw that the bangs were coming, and hurriedly greeted him affectionately: "Comrade Xiao Liu is here." ”

"Leadership." Bangs also say hello.

The secretary hurriedly came in and poured tea for Liu Hai and Sun Aiguo, and then went out and closed the door.

Sun Aiguo opened his mouth and said: "Leader, this time we are here for petroleum equipment, Xiao Liu, you say." ”

"Leader, the pumping equipment is not complicated, but it depends on the depth of the oil well, the working environment, such as the temperature gap, etc., to design the pumping equipment, as well as the viscosity of the oil and so on." Bangs sat upright and spoke.

"Not to mention the artesian well, the Christmas tree can be done, that is, various valves regulate the pressure, flow rate and so on."

"However, most of what is needed is pumping equipment, beam pumping units, which are a bit 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 there any difficulty?" ”

"Yes, the motor drives the pumping unit, and in a working cycle, there are two power generation states, that is, when the pump lifting pressure is very high, it will drive the motor to generate electricity." Liu Hai took out a drawing and pointed it out to explain to the leader.

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

"Now the only solution is to increase the electrolytic capacitance on the DC side of the inverter and reduce the ......." Bangs spoke.

The leader finds that he doesn't seem to understand this?

Well, if you don't understand, the secretary also came at this time, brought the detailed information of the oil field, and then said to Liu Hai: "Take a look?" ”

Bangs opened and looked at it, sure enough, it was big, Qing that place, oil depth and so on.

"Leader, I understand, go back and try it?" Bangs asked.

"Hmm."

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

"Sit down a little longer, although everyone is in the capital, you don't come to us very often." The leader of the first machine department looked at Liu Hai and said when he was leaving.

Liu Hai shook his head and said: "Leader, you are also a busy person, I will not occupy your time, I will go back to study and study first, and come up with a design plan as soon as possible." ”

"Okay, I'll let the driver deliver you." The leader nodded and said.

"No, no, let the factory director take the car later, and I'll drive the tricycle back." Bangs don't dare to sit in a car, there is one in the whole country now, who sits and who is not conspicuous?

Looking at the back of Liu Hai leaving, the leader of the first machine department spoke: "Xiao Liu is still sensible, but someone else is not sensible at all, someone came here to report work, and I thought that the ministry would send a car to send them." ”

Sun Aiguo smiled: "Our department is famous, and I am very happy to be able to sit in this car, maybe I don't have other thoughts." ”

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

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

Sun Aiguo picked up the leader's cigarette and took one for the leader, took one for himself, and lit it for the leader, and then lit it for himself to take a puff: "The work efficiency has been greatly improved, the output has been improved, and many workers have only made a product with higher and higher proficiency, and it is expected that after two months, the production capacity can be increased by 50%, and now it is not necessary to recruit new workers into the factory for a long time, and you can get started after a week, but the yield rate may not be so high at the beginning." ”

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

"That's good, but your factory can do this, the equipment of your factory is the same, and it won't work if you change to another factory." The leaders of the first machine department were also relieved to hear that the production capacity could be increased by 50%.

"If the production capacity is increased by 50%, our side is ready to import a batch of grain from abroad." The leader of the first machine department spoke again.

"Is it so serious? Does the country still need to import grain? "Sun Aiguo is a little confused, is this situation in China now serious?

"Don't mention it, you don't know the situation in the countryside now. Hu eats Haisai, and during the days when the grain comes out, there are three dry meals a day, and when there is no time, it is a paste of wild vegetables, and there is no plan. ”

"Boss Huo on Hong Kong Island has a large amount of cheap grain." The leader of the first machine department opened his mouth to explain.

Sun Aiguo asked in wonder: "Is cheap grain cheaper than what we export?" ”

"Much cheaper than what we export, there are some officials in the former colonies with the British...... Ahem. The leader of the first machine department nodded and did not continue.

When Sun Aiguo heard this, he basically understood...... It's a big deal.

Sun Aiguo asked again: "If we can't do this piece of petroleum equipment, which country are we going to import it?" ”

"It's hard to say, let's see which country has a good design and is cost-effective." The leader of the first machine department took a puff of cigarette and said that now that he has money in his hand, it depends on which one is more cost-effective or something.

"But I have confidence in Comrade Liu Hai, you can see that the pictures of other people have been drawn, most of them are not problems, after you go back, let Comrade Xiao Liu build the equipment, and then pull it over there to test it directly, and use the data to talk about it, and then talk about it." The leaders of the First Aircraft Department directly issued an order to Sun Aiguo.

"That's fine." Sun Aiguo nodded and said.

"How's going with Xiao Liu?" The leader took a sip of tea, and then asked.

"There is no problem with the Lou family, the key is that Lao Lou is not in Kyoto."

"You also know that Lao Lou is still a little old-fashioned, and he wants to meet Comrade Xiao Liu in person, and our secretary has been very busy recently, so I will simply wait for Lao Lou to come back and report on his work." Sun Aiguo opened his mouth to explain.

"That's fine." When the leader heard this, he was relieved.

Besides, after Liu Hai rode three wheels back to the factory, he returned to the maintenance department and began to draw.

"It's a pity that the gas is wasted." Bangs looked at the blueprint, and the gas was wasted at this time.

"A natural gas power plant next year? Then you need a high natural gas pressure pump? Big head! ”

The kowtow machine depends on the distance of the wellhead, and several kowtowers can share an oil storage system.

Of course, Bang Design can only design a separate kowtow machine system, and you can wait for the test to be completed before parallel connection or other things.

The next day, Sun Aiguo slipped to Liu Hai's side and asked, "Xiao Liu, how long will it take for the oil extraction equipment?" I told the equipment department to wait. ”

"It can be done in the afternoon. It's not that complicated. "Bang Hai's words are true, it is really not complicated to build this at the technical level of the motorcycle factory, the motor system, the pumping system, these are not much of a problem.

Sun Aiguo was a little surprised when he heard this: "Is it so fast?" ”

"Leader, I've been preparing here, just saying that I can change it after I get the oil well parameters, you don't think I'm on vacation for half a month, right?" Bangs spoke.

"That's good, that's good, the news from Hong Kong Island has been booked out of 50 cars, but our workshop has not been built yet, and I think the export cars need to be standardized with the kind of parts you mentioned, so that it is convenient for future maintenance." Sun Aiguo said.

"And the mainland will give him a limit of 50 vehicles, if it is more, we will not accept it, mainly because the workshop has not been completed yet, and it is winter."

Bangs nodded, the Commonwealth is basically right-hand drive.

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

Liu Hai knew what Sun Aiguo was talking about, that is, the stamping machine that manufactures arc-shaped steel plates, the tonnage required by this press is not only high, but also the accuracy is also high.

And mass manufacturing with manual is obviously not suitable, the speed of manual manufacturing is too slow, for the leader to ride can be handmade, but normal commercial products are hand-made, although it is not a loss, but the output must not be able to pick up, this is the huge gap between the experimental product and mass production.

Although there is no way to stamping the whole vehicle now, the larger the stamped parts, the better the effect.

Just like the car doors, it must be stamped in place at one time, it is impossible to say that two or three pieces of stamping are welded, so the accuracy of the manufacture can not be seen at all, maybe some doors are closed and look at the gaps are very large.

"Factory director, or do you have to use stupid methods?" The key to manufacturing high-tonnage stamping machines, especially large stamping machines, is the manufacture of stamping modules, hydraulic column strokes, hydraulic pumps, etc.

Because stamping modules are designed to withstand repeated strength, large forging presses are generally used to manufacture them.

In addition, the mold is the same, because of the large stamping parts, when stamping, the force of each mold part is different, if the mold strength can not be reached, it may cause the mold to be damaged, the accuracy is poor, and it may cause the stamping parts to be directly unqualified.

Let's put it this way, the larger the cover, the more things involved, including the travel speed of the hydraulic column, the pressure of the hydraulic column, the distribution of the motor, and so on.

"What's stupid?" When Sun Aiguo heard this, he asked.

"Stacking materials is to add precious metals to the material, so that the material has higher strength and toughness." Bangs spoke.

In fact, the work of piling materials exists in any field, just like the earliest gold finger of chips, it is really gold, and the earliest chips, even in modern times, can be sold at a good price, because of its good materials.

"It's a good thing to try, and we don't lack materials in terms of materials." When Sun Aiguo heard this, he nodded, this is also a direction.

"How long will it take for the oil production equipment to be completed? When the time comes, we will directly produce the parts and try them over there? Sun Aiguo asked again.

Sun Aiguo already wanted to hand over the high-tonnage stamping machine to Liu Hai to be responsible, because Liu Hai was more proficient in this, and everyone else in the factory was talking about question marks, and they didn't know where to start.

"It's not very complicated to make, a week, it's mainly a few jars." Bangs spoke.

"You can rest assured that this can be manufactured by the Nanhua Plant, and after you finish the design drawings, I will send it to the ministry." After Sun Aiguo finished speaking, he saw Liu Hai take out a few drawings and hand them to himself.

"Factory director, that's it, you go quickly, I will hand over the rest of the drawings to the equipment department one after another, and strive to do it in a week." Liu Hai handed the drawings to Sun Aiguo, and then spoke.

Sun Aiguo only went to the ministry in a hurry, and the ministry was also stunned by the efficiency of the motorcycle factory, and only came to see the parameters yesterday, and today he took the drawings, and it was done in a week.

The ministry sent a special person to send the drawings to the Nanhua plant overnight, so that the Nanhua plant could manufacture them as soon as possible.

Nanhua plant began to manufacture pressure vessels in 53 years, and successfully manufactured with the assistance of all parties, so the level of process technology is no problem, if this time all parts of the oil production equipment are all domestic, then it has a huge role in promoting the development of China's oil production industry.

At least you don't have to look at the faces of outsiders to do things.

Liu Hai handed over the drawings to the equipment department one after another, and the rest of the things were waiting for the parts of the equipment department.

Liu Hai was not idle here, and the overall design of the hydraulic system of the 3,000-ton large stamping machine was carried out.

A simple door stamping of 500 tons is about the same, but Liu Hai feels that the 3000 ton press should also be taken out.

The biggest technical difficulty of the large stamping machine is to make the hydraulic column evenly stressed, after all, when stamping, part of the first contact with the parts, this part of the force must be stressed first, and the rest of the parts that are not in contact will not be stressed.

This places strict demands on the entire stamping die as well as the stamping module, as well as on the hydraulic stroke speed.

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

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

The drawings of the bangs were given to the equipment department, and the equipment department was given to the various workshops and rolling mills, urgent tasks, and the rolling mills worked overtime overnight to manufacture.

What kind of process to take, what kind of manufacturing method to take, the first kowtow machine, must be guaranteed for a hundred years...... Ahem.

The motor production workshop of the motorcycle factory made molds overnight, and the Nanhua plant also started overnight after receiving the task.

In less than a week, all parts of the parts were complete, Sun Aiguo, the leader of the first machine department, Liu Hai, and a few workers, took the train to the test place, and the tanks of the Nanhua plant were shipped.

This is a special train, which shows how important the above is to this mission, and Liu Hai also saw that there was a gun, after all, the leader of this train.
