"This is the advancement of technology." Facing the assembled 80 tank, Qin Zhenhua's face was filled with a smile.
The coal-producing diesel engine factory has increased the engine's power to 730 horsepower by using turbochargers. Now, the tank in front of me is planned to be taken out for military parade, and the supercharger used on it is a machine factory.
The latest supercharger developed is under the action of this supercharger that further improves the engine's power performance to 800 horsepower!
"Yes, if you want to talk about this technology, it is also related to the Steyr technology we introduced." Wang Erzhu, who was standing by, was also mixed with emotion: "Pulse boosting technology is so powerful."
Now, the potential of pressing the engine depends on the level of the supercharger. The higher the performance of the supercharger, the more air it can bring in the cylinder.
The ones used in the past can be called a fixed-pressure turbocharger system. This system combines all exhaust pipes together and then introduces them into the turbine. Although each cylinder is exhausted alternately, the volume of the exhaust pipe is relatively thick.
When the turbine blades are reached, the pressure is almost in a constant state, so it is called a fixed pressure boosting system.
Now, this pulse boosting technology is to improve the utilization rate of energy lost in the fixed pressure system. The exhaust gas received by the fixed pressure turbine is stable. After these exhaust gases are discharged from the cylinder, they are expanded first.
At this time, the exhaust energy is wasted. Only about 10% of the exhaust energy is used, even if it is running at full speed, it will not be at most 30%.
Pulse boosting, as the name suggests, is to use the exhaust gas discharged from one cylinder to alternately discharge the exhaust gas, forming a pulse, which is directly introduced into the turbine blade without expansion and pressure reduction. Such exhaust pipes are short and thin.
Reduce the volume of the exhaust pipe, so that the exhaust gas discharged from the engine can be directly and quickly entered the turbine to expand and do work, which will also utilize the energy of the exhaust expansion.
In this way, the turbocharger will be more efficient.
Steyr Heavy Truck also used this pulse boosting technology in the latest engines, and then this boosting technology was used on this tank engine.
The tank engine reached 800 horsepower, which is an innovation, a catch-up and surpass. With such power, the 80 tank will have a more abundant power reserve, and even at low speeds, it has good torque.
It's right.
Now, looking at the assembled tanks, Qin Zhenhua was excited. According to the plan, these tanks were going to participate in the military parade.
"Uncle Luo?" At this moment, footsteps came from behind. When Qin Zhenhua turned his head and saw Luo Ronggen. At this time, the expression on his face was a little strange.
"Built?" Luo Ronggen asked Qin Zhenhua.
"Yes, our factory has gathered skilled craftsmen and made these equipment." Qin Zhenhua happily pointed at the tank that had just been assembled.
"Oh, congratulations, but I have some bad news here." Luo Ronggen's face was not very good at this time, but he always had to say what he should say, and he had no idea to hide it.
"After all, the 80 tank belongs to our new equipment, and the superiors still have some doubts about the reliability of this equipment. In order not to have any unexpected situations, the superiors do not plan to arrange the 80 tank in." Luo Ronggen said.
"What?" Everyone was stunned when they heard this. Everyone worked hard to work. It was normal for such things to prepare for a year or two in advance. However, unexpectedly, the superiors still distrust them.
them.
After all, there has been no military parade for more than 20 years. This military parade is of great significance and absolutely no problem can occur. Now, although everyone is confident, the superiors still have doubts about these fresh products.
After all, it is a fact that many domestic equipment has not been up to standard over the years.
"So, you must be mentally prepared." Luo Ronggen said: "I will also try my best to introduce the reliability of our tanks to our superiors, and strive to let their superiors change their views."
"No, Uncle Luo." At this moment, Qin Zhenhua spoke: "Empty words are untrustworthy, and just saying things are not enough to make the superiors completely believe it. We must do it."
If we could change our views and opinions based on just some paper information, Luo Ronggen would have done it long ago. Now, since the superiors still doubt it, it is reasonable that they doubt it.
Doubt is not scary. Just find a way to dispel the concerns of our superiors.
"Are you planning to invite your superiors to come?" Luo Ronggen asked: "The superiors are busy with troubles, and I'm afraid they don't have time!"
If the leader comes here to see it in person, it is naturally the best. However, how much face does the first machine factory have to let the superior leader come here in person?
This is not easy to deal with.
"Yes, Zhenhua, the idea is very good, but it is difficult to realize it." Old Zhu said along the way.
"No, no, you misunderstood what I mean." Qin Zhenhua said: "Old Zhu, Uncle Luo, have you ever heard of T-34?"
For those who build tanks, if you don’t know the T-34, it’s like the French don’t know Napoleon, and the Americans don’t know Washington, it’s ridiculous. Now, when Qin Zhenhua talks about the T-34, everyone has some
Strange, what did you say about this?
During World War II, the T-34 was widely seen on the battlefield by being simple, solid and easy to produce in large quantities. It was forced to rely on the torrent of armor to flatten the entire Europe and formed the T-34 crisis that caused the Germans a headache.
Until now, the Soviets' tactics are still following the T-34's combat plan. T-72 is actually equivalent to a substitute for T-34.
Now, when Qin Zhenhua talks about T-34, everyone is just puzzled. Why did he raise this matter?
"When the T-34 first came out, it was unknown. The top leaders of the Soviet Union looked down on this kind of tank at all. After all, the Kharkov Communist International factory was just an inconspicuous factory in the Soviet Union.
, and there are various struggles, so the T-34 had no future at first, and the tank designer Mikhail Koshkin knew this deeply."
When Qin Zhenhua said this, Mr. Zhu had already understood: "You mean, let's have a long-distance test?"
Of course, Mr. Zhu knew about this legendary thing.
At the same time, Mr. Zhu also knew Qin Zhenhua, so he immediately captured Qin Zhenhua's thoughts.
