Chapter 208: Testing

He Yuzhu is a big scene this time, dozens of people in the whole hospital eat together, and there is really no way to build a big stove. After watching it for a while, Li Zhao also went home, there is no place for Li Zhao to interfere here, of course, no one has told Li Zhao about this, this matter should have been discussed a few days ago, Li Zhao didn't hear any news.

But think about it, they don't dare to ask Li Zhao for help with this kind of thing, the gap in status is too big. However, Li Zhao was a little puzzled, that is, why He Yuzhu insisted on inviting the whole hospital to dinner, I don't know if this is his own intention, or if someone else asked him to do this, if someone else asked him to do this, then this kind of person should be careful, now in this year, such a person is really a bad person.

If He Yuzhu insisted on inviting him, he could only say that He Yuzhu was a good person, and Lou Xiao'e was really the eldest lady's heart. Of course, with the situation of the Lou family, dozens of yuan are really not in his eyes, Li Zhao thought that he would ask if he had a chance in the future, looking at the situation very similar to the style of the three masters, but maybe he couldn't say.

Early the next morning, Li Zhao came to the rolling mill and still asked Director Yang for leave, but when Director Yang knew that Li Zhao was going to test the engine, he also said that he wanted to go with him, not only that, but also called the superior leaders. Not only that, but also called Deputy Director Li, Li Zhao was puzzled, why did they bring Deputy Director Li this time.

However, this matter has nothing to do with himself, a few people got in the car and came to the material factory, and many people had already come here at this time, including Li Zhao's father-in-law. Li Zhao probably looked at it, they were all high-level military officials, and it seemed that Division Commander Zhang publicized the matter yesterday. Li Zhao went up to say hello to Su's father first, and then greeted everyone, and the group rushed to the military factory, Li Zhao knew that these people should all be going to the artillery.

Sure enough, after arriving at the military factory, Li Zhao and the deputy chief engineer went to the installation workshop together, while the others went to the test site with the chief engineer. When he came to the workshop, Li Zhao saw the parts that had just come out of the ecology, and they had been opened, and Li Zhao stepped forward to start measuring. To be honest, these people are really fast, and I don't know how many people are used.

After the measurement, Li Zhao was satisfied with the accuracy, which was higher than his requirements, so that the effect was better. Then Li Zhao asked the military factory to find and weigh it, and Li Zhao wanted to weigh each part. Seeing everyone's doubts, Li Zhao also explained: "This is a twelve-cylinder engine, and there are many parts here that are the same, especially these running parts, in the process of operation, it is best to achieve dynamic balance, which can reduce vibration." Li Zhao did this just to distribute the weight evenly, after all, the vibration can be as small as possible.

Then Li Zhao also began to introduce the various points of low-temperature assembly, and instructed everyone to put the corresponding parts in the corresponding places, the low-temperature area should be put in the low-temperature area, and the oil bath should be degreased.

At this time, the director of the military industry said: "Chief Engineer Li, let's try the lowest temperature of this low-temperature workshop today, right?" In order to save power, the final temperature was not fully tested. Today happens to have an assembly task, let's test it together, let's see the effect, otherwise we don't feel steady, in case we need to reach a temperature one day, we don't know our ability yet, and it won't be good at that time. ”

Li Zhao heard this, of course, agreed, and said: "Of course it's okay, it's easier to lower the low temperature assembly temperature, it's generally difficult to drop to such a low temperature, and now that there are so many ice machines, it should be able to reduce the temperature very low." After speaking, the factory director also arranged to turn on the ice machine, the effect was obvious, the temperature dropped quickly at the beginning, and after a while, everyone felt cold and began to change the clothes they brought.

Li Zhao's preparation was even more sufficient, and he also brought cotton hats, even masks, etc., you must know that yesterday I said that this time the minimum temperature will be tested, of course Li Zhao should wear as thick as possible. It only took half an hour for the temperature to reach more than minus 50 degrees, and the temperature was still slowly dropping.

After waiting for another hour, the temperature dropped to minus sixty-three degrees, and this temperature basically remained the same, Li Zhao said after looking at it: "This temperature is already relatively low, and it is difficult to do it no matter how low it is." If you need a lower installation temperature, you can only use liquid nitrogen, which is better than direct cooling. ”

The next step is the installation of various components, and Li Zhao is also strict with the installation of this engine, after all, success or failure is here. And this is not a joke, the price of this engine is very high, all the components are calculated, but the cost of raw materials is tens of thousands of yuan, after all, most of them are alloys.

Not only that, Li Zhao estimated that at least dozens of senior technicians were mobilized yesterday, plus the cost of today's installation workshop, the cost of this engine definitely exceeded 50,000 yuan. Li Zhao doesn't want to make a joke about this, and today is the first time to use low-temperature installation, Li Zhao also has the meaning of explaining, so he explains while installing, and the parts will be rotated repeatedly for adjustment after installation, in order to achieve the best effect.

I was busy from morning to afternoon, and I simply ate a little noodle at noon. With the cooperation of several engine assembly masters in the military factory, Li Zhao finally assembled the engine. These masters are also full of praise for Li Zhao's installation skills, you know, the reason why they can be so proficient is that they are completely more pretended. But compared with Li Zhao, they feel that their technology is just like that.

Today, I followed Li Zhao to complete an assembly, and these people all felt that they had learned something, and they originally thought that they were looking down on them by giving a hand to a young man, but as soon as they really got started, they knew that Li Zhao was really a master. With today's installation, they will install the engine in the future, and with the same precision, they will definitely install it.

And today's assembly speed is already very fast, you must know that Li Zhao is a newly designed engine, and the assembly accuracy requirements are relatively high, they are inexperienced, and there is no special tool developed for the installation of the engine, this speed is already very fast. The next thing is the test, these military factories are very familiar, they have a special place for engine testing, these are ready, first of all, test it first, determine the power.

At this time, a crowd of people from the military surrounded him and said; "Chief Engineer Li, do you have any way to optimize the stabilized tail shelling and armor-piercing projectile? We're all satisfied with the power, but the success rate is too low to equip the troops. If you don't make an optimization, let's equip it as soon as possible. ”

Then someone said: "Yes, today the 155-millimeter gun mount has been tried with a new gun mount, and the effect is very good, and now if you don't re-aim, the impact point of 10 kilometers is already within 10 meters, which is already very accurate, and now it is mainly the scarcity of towing vehicles, which can be regarded as finalized production." ”

Li Zhao also smiled bitterly when he heard this: "I'm mainly proficient in machinery, I'm really not proficient in that ammunition, it's better to find me than to find an artillery expert, they may already have a method, maybe they're already designing." Looking for me is really a fish for a tree, I'm not omnipotent. ”

Hearing Li Zhao say this, everyone gave up, and they all looked around at the engine, they had all seen the original tank engine, this one has a slightly different appearance, but the overall size is the same, that is, the bolt fixing holes are the same, so they also understand that this engine can directly replace the existing engine.

The installation was completed quickly, and after checking that everything was correct, the test began. Not to mention, they were really professional, they directly took out a table and measured it item by item according to the content on it. There is a running state under no load, what vibration, noise, speed, etc., and finally Li Zhao looked at their records, all of which are excellent, which shows that in the case of no load, all the performance is better than the current production of the engine.

Seeing this, Li Zhao is already very satisfied, Li Zhao is most worried about vibration and noise, if these two are relatively poor, then there is no need for this engine to be produced again. Because in that case, the operator of the tank suffered, and now it is lowered, then this engine can directly replace the original.

Then there is a load, and it is really excellent, and the power obtained from the final test is about 510, which is the maximum power, and the maximum speed is 2,400 rpm. Due to the slight improvement of accuracy compared to the design drawings, the overall noise and vibration are a little smaller than Li Zhao's estimate, and even better than the current use on the tank. If this engine is replaced, then in the end the comfort of the tank can also be improved a little.

The next step is to put it on the tank for testing, which was prepared yesterday, now it just needs to be installed directly, and soon the installation will be completed and the test will begin. Li Zhao has actually put his mind at ease at this time, and there will be basically no problems in the later tests, but it is estimated that the tank will be driven and take off after a while, and it is conservatively estimated that the maximum speed will reach more than 90 per hour, and I don't know if the tank will be scrapped directly in the end.

Sure enough, as soon as it started, the starting speed of the tank shocked everyone, and the corners of Li Zhao's mouth twitched.

"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.
