Chapter four hundred and eighty sixth pouring cold water
"That's right, we have installed the 730-horsepower engine of the Coal Provincial Diesel Engine Factory on our Storm tank, and we should be able to test it recently." Qin Zhenhua said: "After our tests, the overall performance of this engine should be
It's mature. However, we feel that it would be even better if the engine's power is increased a little more, if it can reach 800 horsepower."
Qin Zhenhua said this, which made Zhang Baolin feel aloof and he saw it. Did he see it? At the meeting, he said arrogantly, how about the 150HB diesel engine, and belittled our X150 engine. Now, he finally admits that his skills are not as good as others?
"Don't worry, our 1,000-horsepower diesel engine has been on the stage and is ready to test the engine. You can wait and see if you don't need 800 horsepower, we will directly provide 1,000 horsepower." Zhang Baolin said.
I finally met Mr. Zhang, so of course I have to show it!
Sure enough, when Zhang Baolin said, Old Zhang's eyes lit up: "You have already started to have a diesel engine of 1,000 horsepower? OK, this is really good news. Our coal provincial diesel engine factory, indeed, this technology research and development is the most powerful.
.”
Now, the project of surveying and mapping the German diesel engine has encountered many problems. The more you move forward, the more problems it has. Needless to say, it has improved on the basis of civilian diesel engines, and military diesel engines have been developed. Just surveying and mapping of civilian diesel engines,
It is difficult to achieve, many of the other people's craftsmanship are too high, far exceeding the domestic industrial level.
This also confirms what Qin Zhenhua said at the time that the starting point of surveying and mapping imitation is too low and cannot work.
However, the plan to increase the cylinder center distance proposed by Qin Zhenhua is now progressing quite slowly. They have to start research from a single cylinder. Besides, there are too many projects in the first machine factory in the past two years, except for this black
Leopard diesel engines, 69 foreign trade tanks, Storm foreign trade tanks, and the country's second-generation tank projects. After all, the scientific research capabilities of the first machine factory are limited after all.
Therefore, the first thing to produce results is the coal province diesel engine factory.
Zhang Baolin said that their diesel engine has risen to 1,000 horsepower. For the country, this is simply a zero breakthrough!
Mr. Zhang immediately praised him.
"Zhenhua, you just wait and see. By the way, what do you think of our X150 engine project?" Zhang Baolin continued to ask happily.
At this time, Zhang Baolin still felt very beautiful in his heart. The first machine factory was very outstanding. After taking the road of foreign trade, the coal-provincial diesel engine factory could not lag behind. Their current engine research and development is the first in China to break through to 1,000 horsepower.
of.
"Do you really want to listen to my opinion?" Qin Zhenhua asked.
"That's certain."
"However, my opinion is still not very optimistic. Are you mentally prepared?"
"Tell me, we just need to listen to the view of pouring cold water on us so that we can spur us and continue to make progress. Zhenhua, your ability to attack people is the highest, we just want to accept the attack, so that we can
Become the driving force for us to move forward.” Zhang Baolin said.
Such a statement made Mr. Zhang, Mr. Huang and others present satisfied. Such a company is a company full of high morale and should be praised throughout the country!
"We went abroad this time and conducted a comparison test with the T-72 tank." Qin Zhenhua said: "This is not a secret. It should have been spread in the system. Our 69 foreign trade tank outperformed the T-72.
tank."
"That's right." Zhang Baolin said.
This is something that all the tank military workers in China feel happy, and Zhang Baolin is naturally no exception. He just doesn’t know what it has to do with the current topic.
"So, why can our 69 foreign trade tank outperform the T-72?"
"Because of the improvement of the cooling system, tanks in such ghost places and cold areas of the Soviets must not be adapted to. We all understand this." Zhang Baolin said.
Of course, they also conducted a careful study and strengthened the cooling system of the 69 tank by the first machine factory. The amazing improvements were sincerely admired. At the same time, they also paid attention to the reasons for the failure of the T-72 tank and the cooling system.
Continue to strengthen!
"That's right, that's it. Later, we took apart the engine of the T-72 tank and overhauled them." Qin Zhenhua said: "When we were overhauling, we also carefully studied the engine of the tank.
”
Zhang Baolin had envy in his eyes. It would be great if he was there at that time! Such an opportunity was rare.
"So, what results did you have found?" Zhang Baolin asked.
"The engine's heat dissipation has a congenital defect. Because the cylinder core distance is small, the distance between the water jacket between the two cylinders is too small, and the power has been increased from 500 horsepower to 800 horsepower. This is the cylinder that should be this kind of cylinder
The limit of the body is that in desert areas, the problem of heat dissipation of this kind of engine is unsolvable."
"How is that possible? Isn't it enough to increase the water tank and increase the circulating water pump?" Zhang Baolin asked.
Qin Zhenhua shook his head: "We tried it after overhauling them, and when we tested it, we increased the heat dissipation from the outside world, which was not enough, because its innate cylinder block has limited its potential, so we
It is estimated that the maximum limit for this kind of engine to increase to 800 horsepower."
After saying that, Qin Zhenhua looked at Zhang Baolin: "Master Zhang, your engine cannot actually run stably on the bench, and there will be various problems, right?"
Zhang Baolin's face suddenly changed: "It is normal for problems to occur after it is on the stage. Isn't this the same thing when we started the current 730-horsepower diesel engine? We finally solved the problem."
"Yes, it's not easy. I encountered many problems when I increased from 500 horsepower to 700 horsepower. The technicians of our coal-provincial diesel engine factory are not simple. They are solved perfectly now, but if the power continues to increase, the problem will be severe.
Now, for example, the problem of the cylinder head explosion." Qin Zhenhua said: "It is impossible to solve this problem by referring to the engine of the T-72 tank. The basic problem is unsolvable."
Zhang Baolin asked to dismantle the T-72 engine. In fact, the real purpose is to find a solution from above and finally mature the 1,000-horsepower diesel engine.
However, this engine has exploded due to rising temperatures in the desert. If you want to find a solution to the problem from a failed product? Of course it is impossible.
Zhang Baolin's face turned a little pale, his throat squirmed twice, and said, "Zhenhua, you splashed this basin of water well, we will be more awake. These problems will definitely be solved if they need to be solved."
