The two found the director of the military factory, and the director of the military factory was also very excited when he heard that the two had brought new engine design drawings and that the power had reached more than 500 kilowatts. Hurriedly arranged for the secretary to call the chief engineer and the deputy chief engineer in charge of the mechanical part, and prepared to let them see it first.

Hearing the power situation introduced by Division Commander Zhang, the factory director can also understand what this means, and you must know that they are also producing tank engines. On this basis, the increase of more than 100 kilowatts, and the size has not changed, it must represent a significant increase in the difficulty of processing, although he is very excited, but still needs to study first.

At present, most of the technical personnel in China are still in the stage of learning and exploring, and basically no one has the ability to come up with a mature design plan. The sudden design of a new high-power engine, and the size of the engine is still relatively small, is really the first case, which also has to make the director cautious.

Soon the two came to the office, the deputy chief engineer Li Zhao didn't know, and the one who had the most contact with Li Zhao was the chief engineer of the entire military factory, and Li Zhao didn't deal much with other people. After introducing the situation, the two also looked at the drawings, and after just a glance, the two knew that it was based on the engine on the current tank.

But after reading Li Zhao's drawings, the two of them also looked solemn and said: "Chief Engineer Li, the accuracy requirements of this drawing are not low, although our factory is confident to manufacture it, but this time is not short, and I think this matching gap is only a little larger than the machine tool, which is much higher than the ordinary mechanical requirements." ”

Li Zhao said at this time: "Yes, there is no way, our machining accuracy is too low, if we do this after the completion of the machine tool project, it will be much simpler." You see that the accuracy requirements of these are all traces, that is, ten microns, that's the reason, in fact, I want to get five microns, but there is no way, that kind of accuracy is estimated that you will take one or twenty days to assemble one, and it will also occupy a large number of senior technicians. ”

"It's also quite difficult for me to design this kind of design, if you can get the machining accuracy to one micron, then I can be sure that I can directly go to the engine of more than 1,000 kilowatts. Now I'm going to settle for the next best thing, setting the accuracy to a slight level, and making do with this engine. ”

"When this engine is produced, I estimate that the noise should be controlled at the current level, and if you want to make the noise and vibration smaller, you need to improve all the accuracy, such as directly reaching the five micron level. The structure I designed is relatively mature, and I only need to continuously improve the accuracy and coordination accuracy to effectively reduce the noise. But that can only wait for the mass production of our machine tools. ”

"However, at that time, there is a good chance that this excessive product will be eliminated outright, and of course it can be developed into a series based on this, but at that time, the design will still need to be re-optimized."

"You look at this kind of accuracy, how long does it take, some of the auxiliary parts on this can be general, that is, the main structural parts such as the body and the cylinder block need to be processed, and the materials also need to be replaced, you need to look at the materials I marked, is there a military factory? If you don't, you'll need to reorder. ”

At this time, the deputy chief engineer said: "I see, we have the materials here, and if you use all the senior technicians for processing, you can probably process them tomorrow." We have a lot of pre-treated materials here that can be used directly. In addition, I see that the materials of these parts are very particular, whether these materials can be used to better play the performance of the engine. ”

Li Zhao didn't expect him to ask this question, so he explained: "Of course, after all, the role of each part is different, such as the cylinder block, this material needs high strength, high temperature resistance, pressure resistance, wear resistance, oxidation resistance and other properties, of course, you need to choose a corresponding metal, which is the most important factors to consider." ”

Li Zhao thought for a while and continued: "Now the engine of the tank can also use this metal use scheme, but it is a bit wasteful. It is mainly a problem of machining accuracy, if the machining accuracy can be up, the current engine can also be optimized, and the engine can be further reduced and reduced. ”

After listening to Li Zhao's words, several people were not surprised, because Li Zhao gave them too much shock, and it was not unusual for them to have something now. At this time, the factory director asked: "Then there is no problem with this drawing?" Then arrange for production, we will assemble it directly tomorrow, and we can also test our new assembly workshop, which has not been assembled in it until now. ”

The deputy chief engineer, who got the order of the factory director, left directly with the drawings, and he needed to arrange production as soon as possible. The director of the factory has spoken, I will try it tomorrow, and now we need to transfer as many people as possible, otherwise it may not be completed tomorrow, you know, the metal required by Li Zhao for these parts is very different from what they usually use, and it needs to be adjusted. In addition, there are many parts that need to be processed, and some parts need to be made into molds.

After the deputy chief engineer left, the factory director continued, "Tomorrow you all have to bring thick cotton clothes, the front assembly workshop just did the test, and finally the temperature dropped to minus 40 degrees, and there was no further drop." We'll test it tomorrow and see how much we can achieve. And with the tank ready, since you want to test the performance, what better way than to get on the tank directly? Your design, the shape has basically not changed, just can be installed directly. ”

Good guy, another ruthless person, of course, this is not to blame these people, Li Zhao's idea sounds too fragrant. With such a high coordination accuracy, if it is installed normally, it will be too troublesome, and it is estimated that it will be difficult to install it with the situation of workers in military factories. In the end, it is very likely that some parts will be directly knocked out of shape.

Li Zhao thought for a while and said: "If you go directly to the tank, then some things of the tank also need to be adjusted, otherwise the performance will not be tried." I'll write you the part that needs to be adjusted later, and you can adjust it directly, otherwise it will definitely be delayed tomorrow. ”

At this time, the director also said: "I still need to make adjustments, yes, I have to write it clearly in a while, how this test effect is very important, you must know that our artillery has made progress, and we need a new tank test." In addition, your design is good, that is, what if the engine fails? The army does not have the conditions to set up an assembly workshop like ours, and maintenance will be a big problem at that time. ”

Li Zhao also smiled when he heard this: "This problem is actually very easy to solve, do you know liquid nitrogen?" For the parts that need to be cooled, you put them in a container, pour a scoop of liquid nitrogen directly, and after a while, the temperature will drop, and the temperature will drop much lower than ours, minus 200 degrees easily. It is necessary to pay attention when using liquid nitrogen, once it is splashed on people, it is easy to get frostbite, and this frostbite is also very troublesome. ”

"In addition, I also consider the maintenance of this issue, if it is used normally, and the processing accuracy is qualified, I think this engine, it is estimated that it will have to run 350,000 kilometers before it needs to be overhauled, and it is usually only necessary to do a good job in the maintenance of the engine. You see the maintenance plan I wrote at the front of the design drawing, as long as they strictly implement it, at least 30,000 kilometers should not be a problem. ”

At this time, several people were surprised, to know that this distance is incredible, with the current fastest speed, all need to run for 500 hours, that is, directly run for more than 200 days, if the usual attendance is average, that is a few years without caring about the engine, so the pressure on logistics is much smaller.

At this time, Division Commander Zhang said: "Good boy, if you can really achieve this effect, it will be great, this is simply the gospel of our troops." Don't you know, this old chariot, as long as you go out, often have one or two directly lying in the nest, if you can have a car that runs tens of thousands of kilometers without breaking, it would be great. ”

In fact, the machinery of this era is still in a relatively bad era, let's say that the army's tanks, like Da Mao's tanks, there are more than 20,000 in this era, if all of them are dispatched at a time, running a 300 kilometers, at least three or four thousand will break down on the way, and these are basically not simple maintenance can be repaired. If you march in a complex environment, the failure rate is even higher, at least more than five percent per 100 kilometers.

However, for Division Commander Zhang's words, Li Zhao could only smile and did not speak, how could a chariot that did not break down at all exist, sixty years later, there are often chariots running and running to run away the tracks, let alone now? It's just that the corresponding failure rate of the engine has been greatly reduced in the future, and as long as the maintenance is not done properly, it is not the same to lie down, and the most important thing is maintenance.

Next, Li Zhao also wrote down the tuning plan of the tank and handed it over to the chief engineer of the military factory, who arranged the adjustment to ensure that it could be used directly tomorrow.

"Brother Shen!"

"Hmm!"

Shen Changqing walked on the road, and when he met someone he knew well, he would say hello to each other or nod his head.

But it doesn't matter who it is.

There was no superfluous expression on everyone's face, as if they were very indifferent to everything.

on this.

Shen Changqing is used to it.

Because this is the Demon Suppression Division, it is an institution that maintains the stability of Great Qin, and its main responsibility is to kill demons and monsters, and of course there are some other side jobs.

Arguably.

In the Demon Suppression Division, everyone has a lot of blood on their hands.

When a person is accustomed to seeing life and death, then he will become indifferent to many things.

When he first came to this world, Shen Changqing was a little uncomfortable, but over time he got used to it.

The Demon Suppression Division is huge.

The people who can stay in the Demon Suppression Division are all powerful masters, or people who have the potential to become masters.

Shen Changqing belongs to the latter.

Among them, the Demon Suppression Division is divided into two professions, one is the town guard and the other is the demon exterminator.

Anyone who enters the Demon Suppression Division starts with the lowest level of demon slayer.

Then step by step, he is expected to become a town guard.

Shen Changqing's predecessor was a trainee demon slayer in the Demon Suppression Division, and he was also the lowest level of the demon slayer envoys.

Have memories of the predecessor.

He is also very familiar with the environment of the Demon Suppression Division.

It didn't take long for Shen Changqing to stop in front of an attic.

Unlike other places full of slaughter, the attic here seems to stand out from the crowd, and in the bloody Demon Suppression Division, it presents a different tranquility.

At this time, the attic door is open, and there are occasional people entering and exiting.

Shen Changqing only hesitated for a moment, and then stepped in.

Access to the attic.

The environment has changed in vain.

A burst of ink fragrance mixed with the faint smell of blood came to his face, making his brow furrow instinctively, but quickly stretched.

The smell of blood on everyone's body in the Demon Suppression Division is almost impossible to clean.
