"Mr. Zhu, you are not from the R&D department? No wonder, your vision is higher than theirs." Qin Zhenhua said with a sigh.
He didn't know that Mr. Zhu came down from above, but he knew that Mr. Zhu had the same views on tanks as he did, and he felt that heroes saw the same thing.
When we first started producing the 59 tank, it was almost at the world's leading level. However, it has not changed over the years. The 59 tank has been in production for decades and has long fallen behind.
This is the research and development room of the factory. It should have been aimed at the world's advanced level. However, look at the thoughts of the people here now. Are they still saying that the 59 tank is good and the 59 tank will conquer the world? The concept has long been outdated.
!
"Of course not, Mr. Zhu is..." Just when Song Weize was about to continue, he looked at Mr. Zhu and waved his hand: "Forget it, don't talk about me, let's talk about this tank. This young man has a lot of opinions.
, I’m still waiting for my evening train to go back. Now there are only more than three hours left, and I really want to see how to assemble it in place. Since the first time we took it apart and put it back together, it hasn’t moved.
It would be great if it could move before I leave."
Zhu Lao's eyes were looking at Qin Zhenhua eagerly. Being stared at by the old man, especially looking at his empty sleeves, Qin Zhenhua felt that there was no need to talk anymore.
Go ahead.
"Okay, then I'll do it." Qin Zhenhua said: "This hydraulic transmission system is inevitable for the development of tank transmission systems. However, for us, it is still a new technology, so many people cannot master it correctly.
Its principles and maintenance, first of all, are here.”
Qin Zhenhua said, pointing with his hand: "According to the instructions for use, the hydraulic oil filter must be replaced every one hundred motorized hours. If it is not replaced, it may cause the precision hydraulic pump to malfunction.
I think this place is clean and no one has touched it."
Zhu Lao's eyes suddenly lit up: "That's right, we haven't touched it at all. We always feel that there will be no problem here!"
If Mr. Zhu had studied for a few more days, he would definitely have discovered the doorway here, but he just came over to take a look, and there was no need to do it himself. The inspection time was very short, and he heard that they had cleaned up the oil circuit, so there was no need to do it at all.
I didn't think about it here.
Zhu Lao was here and Song Weize was here, so although Du Youwen was very dissatisfied, he still didn't say it out loud. The tank's transmission system had been disassembled and assembled several times, but the fault could not be solved. It was precisely because of this that Zhu
He just came here, but after all, he is busy with work and has not stayed here for a long time. He has been tinkering for a long time but can't get it right. Can Qin Zhenhua solve it?
That filter is outside the entire hydraulic transmission system, so what is its use? If something goes wrong, the most likely cause is the torque converter!
The power of the engine must be transmitted through the transmission shaft, gearbox, and finally to the driving wheels. This is very similar to that of a car. If it is a clutch using friction plates, it is the most common form. Our 59 tank uses this principle, and
The hydraulic transmission system is not. It is not directly hard-connected, but through a device called a hydraulic torque converter.
To put it simply, the output shaft of the engine is connected to a fan blade. The blade rotates whirringly, stirring the liquid. The liquid flows forward, flows to the opposite fan, and drives the opposite fan to rotate.
This is like having two electric fans facing each other. If one blows air, the other will follow suit. It just turns the air into hydraulic oil.
Of course, the specific design is more complicated, but the principle is like this. This kind of hydraulic torque converter must consume a certain amount of energy, but the benefit is better buffering. In the AT gearbox on the car,
This structure is also used.
Everyone focuses on the torque converter, which has been disassembled and reassembled several times, but they have never considered the filter. It doesn't make any difference whether it has it or not, right?
Qin Zhenhua said as he closed the valve, then reached in, tightened the filter shell with a special steel belt, and disassembled the filter in a few clicks.
At the moment of disassembly, his hand held the bottom firmly and dismantled the device without bringing out a drop of oil.
"Here, find a piece of paper to put on your back." Qin Zhenhua said.
In the factory, waste newspapers were everywhere. On top of the waste newspapers, Qin Zhenhua turned the filter upside down. Suddenly, the black oil inside flowed out, along with a lot of thick sludge. The entire filter
, they were all blocked tightly.
Looking at the filter, Mr. Zhu patted his head and said, "We were negligent. It is indeed the problem with this filter! It's difficult for those who don't know how to do it, but it's not difficult for those who know how to do it!"
There was no need to put on a new filter to test the car. Zhu Lao knew that this inconspicuous little thing must be causing trouble. It was blocked inside and the flow of hydraulic oil was difficult. Naturally, the entire hydraulic transmission system could not be stabilized.
It's running.
"Qin Zhenhua, you just came here, how did you know there was a problem here?" Song Weize was also surprised for a while. This kid is simply omnipotent.
"Because I came from a maintenance workshop. When we perform maintenance, we not only need to use our hands, but also use our brains. If you dismantle it without a brain, it will only get worse and worse." Qin Zhenhua said: "We must be familiar with the principles and then judge the fault.
, taking action is the last step. If I come up and dismantle it randomly, I will probably get sprayed with oil in the end."
Du Youwen's face turned red to the root of his neck. The clogged filter would cause negative pressure in the entire hydraulic pipeline. If the power was continued to be increased during the test run, the pipeline would burst and spray all over him!
I only focused on checking the pipelines and the assembly of the torque converter, but I didn't check such small accessories!
"This kind of filter has a very high filtration accuracy. It won't work with ours. Let's clean it and reinstall it." Qin Zhenhua said, handing the filter to Du Youwen: "Here, you
Responsible for cleaning it."
Why me? There was a hundred and twenty reluctances on Du Youwen's face. I am a technician in the R&D room, and you, an apprentice worker, are commanding me?
"We still have to disassemble the hydraulic pump and take a look. If the hydraulic oil is not clean, the pump body may be scratched. Director Song, find me a magnifying glass."
Damn it, how far has this pretense gone? This is a tank, not a creature being observed in biology, or an agent looking at microfilm. Why do you need a magnifying glass?
Du Youwen was conflicted in his heart. Before he received the filter, Director Song had already spoken: "No problem, I'll find it for you now."
Zhu Lao nodded with satisfaction. This young man looks very young, but in terms of professionalism, he is definitely good. It seems that the surveying and mapping imitation of the entire system can be left to him. As for others, no, it is too easy.
You have made an empiricist error, and you don’t realize the significance of your current work at all!
