Chapter 70 Filter Failure

"Zhu Lao, you are not from the R&D room? No wonder, your vision is higher than theirs. Qin Zhenhua said with a sigh.

He didn't know that Zhu Lao was from above, but he knew that Zhu Lao's opinion on the tank, like himself, had a feeling that the hero saw something like him.

When we first started producing the 59 tank, it was almost at the world's leading level, but over the years, it has not changed, and the 59 tank has been produced for decades and has long been behind.

This is the R&D room of the factory, which should have been aimed at the world's advanced level, but now, looking at the thoughts of the people here, they are still saying that the 59 tank is good, and the 59 tank is the world? The concept is outdated for a long time!

"Of course not, Zhu Lao is but..." Song Weize just wanted to continue, so he looked at Zhu Lao and waved his hand: "Forget it, don't talk about me, let's talk about this tank, this young man, I have a lot of opinions, my train at night, I'm still waiting to go back, there are more than three hours left, I really want to see how to assemble it in place." It hasn't moved since the first time we took it apart and put it back together, and it would be nice if it could move before I left. ”

Zhu Lao's eyes looked at Qin Zhenhua eagerly, and was stared at by this old man's gaze, especially looking at his empty sleeves, Qin Zhenhua felt that there was no need to move his mouth again.

Let's do it.

"Okay, then I'll do it." Qin Zhenhua said: "This kind of hydraulic transmission system is the inevitable development of the tank transmission system, but for us, it is still a new technology, so many people can not correctly grasp its principle and maintenance, first of all, it is here." ”

Qin Zhenhua said, pointing with his hand: "The filter of hydraulic oil, according to the instructions for use, must be replaced every 100 hours of motorization, if it is not replaced, it may cause the precision hydraulic pump to malfunction, I think it is clean here, no one has touched it." ”

Zhu Lao's eyes suddenly lit up: "That's right, we haven't touched it at all, I always feel that there will be no problem here!" ”

If Zhu Lao studied for a few more days, he would definitely be able to find the doorway here, but he just came to take a look, there was no need to do it himself, the inspection time was very short, and he heard that they had all sorted out the oil road, so he didn't think about it at all.

There is Zhu Lao here, and Song Weize is here, so although Du Youwen is very disappreciative in his heart, he still didn't say it, the transmission system of this tank has been disassembled and assembled several times, and it has never been able to solve the fault, it is precisely because of this that Zhu Lao came over, but after all, he is busy with work, and he has not been here for a long time, and he has not been able to figure it out for a long time, so Qin Zhenhua can solve it?

What can that filter be used for outside the entire hydraulic drivetrain? If there is a failure, the biggest possibility is the torque converter!

The power of the engine is transmitted to the drive wheels through the transmission shaft, gearbox, and finally to the drive wheels, which is very similar to the car, if it is a clutch with friction plates, it is the most common form, and its own 59 tank is this principle, and the hydraulic transmission system is not, it is not directly hard connected, but through a device called a torque converter.

To put it simply, the output shaft of the engine is connected to a fan blade, which rotates whirringly, agitating the liquid, and the liquid flows forward, flows to the opposite fan, and drives the opposite fan to rotate.

It's like two electric fans facing each other, one blowing, and the other spinning, but turning the air into hydraulic fluid.

Of course, the specific design is more complex, but the principle is like this, this kind of torque converter must consume a certain amount of energy, but the advantage is that the buffer is better, and the AT gearbox on the car is also used in this structure.

Everyone paid attention to the torque converter, disassembling and assembling it several times, but they didn't think about the filter.

Qin Zhenhua said as he closed the valve, then reached in, fastened the shell of the filter with a special steel belt, and disassembled the filter in a few clicks.

At the moment of dismantling, his hand held the bottom steadily, and without bringing out a drop of oil, he removed the device.

"Here, find a piece of paper to pad." Qin Zhenhua said.

In the factory, waste newspapers were everywhere, padd on the waste newspapers, Qin Zhenhua turned the filter upside down, and suddenly, the black oil stain inside flowed out, and there was a lot of thick oil sludge, and the entire filter was tightly blocked.

Looking at this filter, Zhu Lao patted his head: "It's our negligence, it's really the problem with this filter!" Those who are difficult will not, and those who will will not be difficult! ”

There is no need to put on a new filter for testing, Zhu Lao knows that this inconspicuous little thing must be doing a trick, it is blocked inside, the flow of hydraulic oil is difficult, and naturally the entire hydraulic transmission system cannot be operated stably.

"Qin Zhenhua, you just came here, how do you know that it is a problem here?" Song Weize was also surprised for a while, this kid is simply omnipotent.

"Because I came from the maintenance workshop, we engage in maintenance, not only hands, but also brains, no brains to dismantle, can only be dismantled more and more bad." Qin Zhenhua said: "You must be familiar with the principle, and then judge the fault, and hands-on is the last step." If I come up and dismantle it, I guess I'll end up spraying oil. ”

Du Youwen's face was red to the root of his neck, and the filter was blocked, which would cause negative pressure in the entire hydraulic pipeline.

I only care about checking the pipeline and checking the assembly of the torque converter, but I haven't checked this kind of small accessories!

"This kind of filter, the filtration accuracy is very high, we can't use ours, let's clean it and reinstall it." Qin Zhenhua said, and handed the filter to Du Youwen: "Come, you are responsible for cleaning it." ”

Why me? Du Youwen's face was one hundred and twenty unwilling, I am a technician in the R&D room, and you are an apprentice, commanding me?

"We still have to disassemble the hydraulic pump to see, if the hydraulic oil is not clean, the pump body may be scratched, Director Song, find me a magnifying glass."

Nima, what is this pretending to be? This is a tank, not biology to observe any creature, not an agent to look at microfilm, what do you want a magnifying glass for?

Du Youwen was resistant, and he hadn't received the filter yet, but Director Song had already spoken: "No problem, I'll find it for you now." ”

Zhu Lao nodded with satisfaction, this young man, he looks very young, but, to say the degree of professionalism, it is absolutely good, it seems that the whole system of surveying and mapping imitation can be handed over to him to do, as for others, no, it is too easy to make empirical mistakes, and I don't realize the meaning of my work at all!
