Chapter five hundred and fifty-eight problems that cannot be solved
Surveying, mapping and imitation are not that easy. You know the size of a simple component. However, when you process it yourself, if you cannot process the same accuracy, the quality gap will be huge. You know others'
Materials, you know the proportion of various elements, but when you smel them yourself, you cannot smel out the same material.
There are also many process problems, such as the other party adding an additional wear-resistant coating to the cylinder wall, which I don’t know how it is done.
In this case, how to imitate it?
If you want to imitate, you must reach the original level. If the quality of any part does not meet the standards, the imitation will be inferior products, and the overall performance will not be able to meet the standards.
When they study carefully, the deeper they study, the more chilling the conclusions they get. They are unable to complete surveying and mapping imitation, and at least in a short time, they will not be able to solve these problems.
This is the gap between the entire industrial system and others.
Just like France, the whole world sells arms, but people are not worried that their arms will be copied. Take the Phantom 3 fighter jet for example. Until now, only Israel can copy them, because Israel stole Phantom 3.
All design information.
It is absolutely impossible to imitate just one plane.
The Germans have enough confidence to sell this civilian engine. They can guess that even if the Eastern powers want to survey and map and imitate it, they cannot do it. In the end, they have to buy diesel engines from Germany obediently.
Even if you only purchase this civilian model and equip them with their new tanks, it is a big business, with at least a few hundred units.
The tank engine produced by MTU in Germany is Mount Everest in the engine field, and it is not so easy to imitate.
Take Asan for example. All the bulk parts they imported from Germany were assembled in their own factories. Just the assembly process problem made the original 1,500 horsepower engine only emit less than a thousand horsepower.
The motivation comes.
This is the gap, the huge gap!
Even if the engine is placed in front of you, disassembled and installed, the power data can be at least 20% dropped~
Now, when Zhang Baolin was making this report, he felt that it was full of all kinds of flavors.
After all, this is a national key project. The country has invested huge amounts of money, but it has achieved such a result, which is very sad.
However, he must admit that otherwise, if we continue to study, it will only cost more money, and it will be impossible for them to overcome these problems in a short time.
"At present, we admit that these problems encountered cannot be overcome in a short period of time. Therefore, in order to prevent their tank engines from being affected by our problems, we hope that in this meeting, all the experts will work together to come up with a
The right plan comes."
When Xiang Dayang finished saying this, the following was still silent for the time being.
Most experts have attended the last meeting. A few years ago, everyone still valued this plan very much and thought it was the most suitable plan. They first imitated the civilian model, then increased the horsepower, and finally reached the goal of
-2 Same power standard.
Now, after hearing about this 8V165 engine and having encountered so many problems, everyone's hearts are naturally mixed.
"Why is this happening? Aren't the prototype made?" At this moment, someone asked a question.
"Yes, our engine station cannot fail. Everyone wants to save face, so we built a prototype first. However, on the bench, the maximum power can only reach 667 kilowatts, which is still far from the standard.
It's far away, and this engine cannot continue to operate stably, and various problems arise one after another, such as cylinder pulling, fuel injection pump plunger stagnation, and supercharger surge, all because of our materials and processing technology.
However, in order to ensure that it can operate stably, we have continuously reduced the power standard to 537 kilowatts. Even so, the problem cannot be solved."
Now, the domestic coal-provincial diesel engine factory has built a 537 kilowatt engine, which is used on 80 tanks and storm tanks, and can at least run stably. However, the engine made by the engine has the original specifications of high standards.
As a result, even if it is lowered to the current level, it cannot operate stably. Overcoming these problems is a long way off.
"Our domestic technology is too backward." Xiang Dayang said: "Take the pistons as an example, we don't know how they processed them. By the way, Zhenhua, do you think there is a way? Please ask the German company to give it to you.
Transparently provide some technical support?”
Xiang Dayang is also an expert in the engine institute. Now that they have put forward this idea, they can no longer solve it. If they want to continue the engine, they can only ask for help from abroad.
Hearing this request, Qin Zhenhua shook his head helplessly: "That is absolutely impossible. We have surveyed and mapped to imitate other people's products, which is already considered to be a violation of the basic international standards. We are infringing on the rights. Now, we have violated other people's power and demanded that
Is someone providing technical support? I'm afraid I'll be beaten by the Germans."
In China, concepts about technical patents are now slowly forming. If it were in the past few years, these were all natural. So what about surveying and mapping imitation? Is the idea considered money? Capitalists are too profitable, right?
Now, everyone can accept it.
"If we don't get their technical support, our project will have a bad future." Xiang Dayang said, his words were filled with endless loneliness.
"Let's take a look at the other two diesel engines. When the surveying and mapping project is not going well, we are fortunately there is a backup plan." said the host of the meeting.
In fact, everyone is very expecting surveying, mapping and imitation. This is an expectation to move towards the advanced level of the world. Now, this hope has been broken.
Without diamonds and not taking on porcelain work, the country supports the most in this project. It requires money and people to give people, and concentrates the country's resources to do it. As a result, it has become a four-dimensional person.
Zhang Baolin stood up: "After the last meeting, our coal provincial diesel engine factory has developed the X150 diesel engine according to the original plan. Through the supercharged intercooling plan, we got 706 kilowatts of power during the test run.
data."
As soon as these words were said, they immediately attracted everyone's attention. There is always a way to do it if the east is not bright, and the backup plan here sounds very progress!
