The engine is the embodiment of the industrial foundation. Without a modern industrial foundation, there would be no advanced engines. It also involves various issues such as materials, processing, etc.
Throughout the world, MTU is at a first-class level in engine manufacturing. Not only tank engines, car engines, warship engines, etc., they are all star products.
The next day's visit was to the MTU company. When everyone walked into this famous international company, they saw a cleaner and tidier scene than the Leopard 2 tank production workshop. Not to mention oil stains on the ground, even dust.
nothing.
"In order to make the engine assembly more clean and tidy, we use a dust-free workshop during the final assembly."
Even a grain of sand falling into the engine will accelerate the wear of the engine. Therefore, MTU, which strives for excellence, uses a dust-free workshop.
Of course, you don’t need to reach the level of an electronics factory, but equipment such as shoe covers and dust caps are still necessary. This is the first time that everyone has seen such excellence and they all feel emotional from the bottom of their hearts. No wonder their engines can be ranked first in the world.
First, every assembly link is of such high standards.
Eric, the person in charge of the company, personally received him and introduced him to everyone.
"Here, civilian diesel engines and military diesel engines are produced on the same line. The current batch is our 331 engine. Its military version is used in the Leopard-2 tank." Eric introduced: "
Compared with military models, this engine reduces the speed to 2,400 rpm for stability and durability, and the power is further reduced."
At this time, the beginning of the production line started with the assembly of cylinders. Looking at those shiny cylinders, everyone opened their eyes wide. Zhang Baolin even came to the front and observed carefully.
"No, this cylinder is an 8-cylinder one, right?" He couldn't help but ask.
The Leopard 2 tank used a 12-cylinder engine, but now, he saw an 8-cylinder engine. What's going on?
"Our civilian engine is a series." Seeing that Zhang Baolin was interested in this cylinder, Eric knew what he was thinking and continued to introduce: "Our 331 series engine has
There are multiple models of 6, 8, and 12-cylinder turbocharged and turbocharged intercoolers, so that different power outputs can be achieved. At the same time, the single-cylinder displacement is exactly the same, and the basic structure and overall layout are almost the same. This can
Greatly reduce production costs.”
A series of engines!
The tank engine can be said to be the most difficult and requires the most power. After it is converted to civilian use, it may not need such a large power. At this time, they will reduce the power. Reducing the number of cylinders is the most convenient. Overall
The structure is still the same, many parts are common, and the cost is greatly reduced.
Zhang Baolin's eyes lit up. He could still do it like this. This was a good plan. He could do it like this in the future too!
After passing the production line, when we came out, there were several workshops next to each other.
"Everyone, please come here. Let's go visit the cylinder casting workshop." Eric was about to take everyone away, but at this moment, Qin Zhenhua seemed to have discovered something, and couldn't help shouting: "This way.
That’s the turbocharger processing shop, right? Can we go in and have a look?”
A workshop opposite could see a sign in the shape of a small fan, so Qin Zhenhua guessed that it was most likely a turbocharger production workshop, which was very attractive to him.
If you want to advance the technology of the engine, you must increase the power of the single cylinder. Turbocharging is the only way. The processing of this blade is also the top priority in Qin Zhenhua's plan after returning.
Since I came here this time and saw it, of course I had to go in and take a look.
Hearing what Qin Zhenhua said, Commander Huang also became interested: "Can we come in here and have a look?"
Qin Zhenhua is a small entourage and is very young. The other party does not need to listen to his words. However, Commander Huang's words are different. After Commander Huang finished speaking, Minister Zhu also expressed interest, so Eric also
It can only disrupt the original plan.
Just look at it, what can a group of people from a backward country understand?
If you take them in, walk around in a circle, and then come out again, it won't take too long. After all, this workshop is not big, and the area is less than one-twentieth of the final assembly workshop.
"The turbochargers for our engines are produced here." Eric said, leading everyone inside.
Just now, Qin Zhenhua walked here and asked to go in for a visit, so when he opened the door, he was at the door, and a new world unfolded before his eyes.
He glanced at the CNC machine tool at work. The entire machine tool was spotless, and the paint on the outer shell was brand new and shiny. In the center of the lathe, inside the plexiglass cover, workpieces were being processed. This completely sealed the workpieces.
Standing up for processing can ensure the safety of the operator and ensure that there will be no additional interference during processing. It is a common method for CNC machine tools.
And, what did you see?
The workpiece now is rotating around a certain axis! It is definitely not a three-axis CNC machine tool, but a five-axis CNC machine tool!
As a result, young Qin Zhenhua had forgotten everything. He was so excited that he thought about it countless times in his mind. It would be much more convenient if there was a five-axis machine tool to process the impeller. Now, he finally saw it.
, so, no longer hiding his excitement, he ran there.
Five-axis linkage CNC machine tool, five-axis linkage CNC machine tool! This is the first time I have seen it. It is several generations ahead of my own homemade CNC machine tool that requires manual coding!
Qin Zhenhua thought like this, and finally turned his eyes from the bed of the machine tool and looked to the side. The machine tool itself has a display screen and various operation buttons. At the same time, on one side of the machine tool, there is a computer desk next to it. On the computer desk,
Is there a personal computer?
The beige casing, the TV-like protruding display, the keyboard and body underneath are all put together, and the entire computer looks like an exquisite household appliance!
It should be the Apple II, right? The latest computer from Apple. Although the size is less than one-tenth of my DJS-130, its performance is many times higher!
At this time, a female technician with a slightly frowning brow was sitting in front of the computer. She was very unhappy when she saw an unknown person running in, but when she followed, she recognized him.
"Why is it you again? What are you doing here?" As soon as the girl's voice came out, Qin Zhenhua was also stunned. At this time, he had already run to the CNC machine tool, panting heavily, pointed at the machine tool, and said: "Visit,
Come and visit.”
She stood up, crossed her arms on her chest, and said with a sneer, "Are you interested in CNC machine tools?"
The tone of voice is exactly the same, and the words are all in English, just like yesterday when I asked Qin Zhenhua, are you interested in heavy trucks?
