Chapter 225: Hydraulic system

What's the trouble?
The gun barrel slid into Shiyan.
Due to the angle, the distance behind the tank is also very short, and it is impossible to reverse.
The only way is to forcibly rotate the turret to force the barrel to "slash" out of the stone. This means that at least the turret needs to be rotated more than fifty degrees.
However, the rock into which the barrel is inserted is relatively deep. Forcibly rotating the turret may cause the working motor to burn out.
After all, the weight of the turret itself is more than ten tons!
Coupled with the resistance of Shiyan to the barrel, the motor's endurance is very terrible.
Both Ding Mao and Peng Deming are very worried that the motor will be overloaded.
After all, this is a tank!
It's not an excavator.
There is also a hydraulic system.
Who knows whether the hydraulic system of the turret can support it?
You know, the hydraulic systems used in Type 59 tanks are all relatively old. The bearing capacity is only about 100 Pa. Exceeding this pressure will "burst."
What are the consequences of bursting?
But the turret can no longer turn. lag.
What are the consequences of the jam?
The entire Sichuan-Tibet line will be blocked here.
Unless blasting is used, the barrel cannot be pulled out.
but……
Blasting in such a dangerous place...
Even the most experienced blaster dare not!
Don't make a loud rumbling, the whole mountain is falling down. Bury all the tanks directly alive.
Very sorry!
The hydraulic standard of the old Type 59 tank is too low.
In today's world, the most advanced tanks, such as Leopard 2 and the like, have a hydraulic system that can withstand more than 250 Pa.
The gap between the two parties can be seen. It's not a level at all.
Indeed it is.
The Type 59 tank can only be considered the first generation.
Now they have developed to the third and fourth generations. The first generation of antiques has long been dumped into the Mariana Trench.
"Turn it. It's okay." Wang Buan said confidently.
"Are you sure?" Peng Deming was dubious.
"I'm sure." Wang Bu'an said affirmatively.
Of course he was sure.
Because the hydraulic system has been replaced.
When manufacturing general-purpose chassis, he also strengthened the hydraulic system attached to the chassis.
The new hydraulic system has a bearing capacity of more than 5000 Pa. What is a small 250 Pa? Not to mention a ten-ton turret. Even if it is a hundred tons, it is easy.
"it is good!"
"turn!"
Ding Mao categorically ordered.
Wang Tianlai turned the turret himself.
Sure enough, the barrel slowly forcibly cut a crack in the rock.
"Wow!"
"Boom!"
Large pieces of rock fall off.
People who don't know the details thought it was a cave-in.
Almost all the places where the gun barrel crossed were granite, very hard. But it is always unable to stop the powerful pressure of the barrel.
In the end, the barrel was successfully detached from the rock.
Everyone hurriedly checked the rotating motor.
It's okay.
Check the hydraulic system.
normal.
The only thing that is abnormal is the barrel.
Due to the strong resistance of the rock, the barrel was bent to a certain extent. Obviously it cannot be used normally.
Fortunately, it is an ancient 100mm rifled gun. The cost is not high and the damage is not heartache.
If it were a brand new 120mm smoothbore gun, the loss would be great.
Wang Hao, Wang Tianlai, and Wang Yongbo were all criticized.
Continue on the road.
The atmosphere in the carriage is a bit dull.
After all, all three families have been criticized. Naturally, the mood will not be very good. No one is in the mood to speak.
Wang Bu'an did not speak either.
He was thinking about that rifled gun silently.
Obviously, the quality of this 100 mm rifled gun is not very good. Not strong enough.
If it is strong enough, it can be used as an excavator.
Wang Buan inspected it with the No. 1 Robot Wizard and found that the alloy used in the barrel had a yield strength of only about 300 Pa.
Obviously, this yield strength is far from enough. The yield strength of aircraft carrier deck steel is over 800 Pa. As the barrel of a tank gun, even the deck steel of the aircraft carrier is far inferior, and it is obviously very backward. The only advantage is that it is probably cheaper. It doesn't hurt if it's broken.
However, Wang Bu'an's focus was not the gun barrel.
This is the research scope of the defense industry.
A special research institute is responsible for studying tank guns. No need for him to intervene.
His focus is on motors and hydraulic systems.
These are two huge business opportunities.
In other words, they are also the two weaknesses of my country's manufacturing industry.
High-power motors have very high requirements for raw materials and manufacturing processes. The requirements for reliability and stability are also very high.
The hydraulic system has always been relatively backward. my country's own scientific research strength is not strong.
Hydraulic transmission has become an important basic technology for modern mechanical equipment and electromechanical products, and has a very wide range of applications in the field of industrial machinery.
The application areas of hydraulic systems include: industrial production {forging machinery, injection molding machines, machine tools, processing centers, robots, mining machinery, packaging machinery, etc.}, mobile machinery {construction machinery, construction machinery, agricultural machinery, automobiles, etc.}, aerospace { Aircraft, spacecraft, satellite launchers, etc.}, ships {ship and ship deck machinery, operation and control systems}, marine engineering {ocean development platforms, subsea drilling, underwater operations, etc.}.
Taking foreign countries as an example, about 95% of construction machinery, 90% of CNC machining centers, and 95% of automated production lines use hydraulic transmission.
It seems that the excavator used by Zheng Haifeng, no matter what brand, is the core technology, which is actually the hydraulic system.
The key technology of the world’s largest super excavators and super cranes is also the hydraulic system.
As for the military industry, the hydraulic system is even more important.
The aircraft's landing gear, wings, and various transformations all require hydraulic system support.
Needless to say, the take-off and landing aircraft of the aircraft carrier and the blocking cable.
However, my country's hydraulic system technology has always been backward.
Some companies even cheat.
According to previous news reports, a large enterprise in Shandong Province had a situation of technical fraud.
They repainted the hydraulic pump they purchased from Toyo Kawasaki, marked with their own brand, and passed the national acceptance.
This company used similar methods to defraud the country of up to 1.5 billion scientific research funds.
The incident was exposed and the whole country was in an uproar. The company involved went bankrupt.
However, the industry disagrees.
Some people even broke the news that there are many similar companies.
On the one hand, our technology is not good. No one wants to settle down and concentrate on research.
On the one hand, it is the country's urgent need for hydraulic systems. Do not hesitate to use high funds to encourage enterprise innovation. As a result, it was taken advantage of by some unsuspecting people.
What does this indicate?
It shows that our country really needs sophisticated hydraulic systems.
Whether it is military or civilian.
Leave the military alone. Let's talk about the civilian use first.
Let's talk about defeating Komatsu, Hitachi, Carter and the like. Otherwise, the world's high-end excavator market will always belong to others.
From the perspective of construction machinery alone, we are indeed a super manufacturing country.
However, high-end hydraulic systems still need to be imported.
Others can pinch yours at any time.
There was a traffic jam ahead.
But someone's car broke down.
This situation is very common. Especially above the Sichuan-Tibet line.
It's just that the location of this car's breakdown is a bit special. It happened to be on a very narrow road. There is no way to know a car. As a result, both ends are blocked.
The road is only about four meters wide. On the left is the dug out cliff. On the right is the tumbling river.
If you are not careful, you may fall into the cold river water, and no one can save it.
Liang Ge's tank happened to be the leader, so he went down to check.
"Grass, what a broken car! Just push it into the river."
"The tank is coming! Get out of the way!"
"Comrades of the People's Liberation Army, push that broken car away with a tank!"
"What a broken car! You can't even go on the Sichuan-Tibet line! Throw it into the garbage dump as soon as possible! Or else, push it into the river!"
"Others are Land Rover, OK? More expensive than your Lu Xun!"
"Get out! Get out everyone!"
Finding that there is a fleet of tanks, many people are excited.
But they were all stuck at both ends, and they were very upset.
Wang Buan climbed out of the tank and stood on the turret to watch the excitement. The damage was found to be a Range Rover. The front cover has been opened, and several young people are tinkering.
Vaguely, one of them seemed to be familiar. But the distance is too far to be recognized.
He didn't care. Anyway, Liang Ge has gone to the front to deal with it.
There should be results soon.
"British things are like this." Wang Hao said.
"It was made by Indians." Wang Tian said.
"Then it's even more unreliable." Wang Yongbo finally concluded.
As if to confirm his words, Liang Ge went to the front to deal with it for a while, but the Range Rover still did not drive away.
On the contrary, the crowd onlookers is increasing. Someone started yelling impatiently.
After all, Wang Bu'an was a young man, and couldn't help running to the front to watch the excitement.
It's okay not to look at the result, but at first glance it turns out to be an acquaintance.
Still a former enemy.
Tan Bowen.
Owner of a Range Rover.
This guy also ran to the Sichuan-Tibet line. It's really fate.
Tan Bowen apparently also saw Wang Bu'an. He was taken aback for a moment. Immediately, as if he had found a savior, he waved to Wang Bu'an again and again.
"What are you doing?" Wang Bu'an said blankly.
"Help, take us to Zhicheng. There is a car repair shop there." Tan Bowen said helplessly.
"How is your Land Rover?"
"The engine is broken."
"The engine is broken?"
"Yeah! Too bad. When is it not bad, it happens to be bad at this time."
"Ha ha."
Speaking of this matter~EbookFREE.me~ Tan Bowen is also very depressed.
I thought Land Rover had a strong off-road ability. That's why I bought one. There are also many Land Rover on the Sichuan-Tibet line. There is no problem with others.
It happened to be his own problem. It's the engine problem. It can't be repaired completely.
In fact, even in Zhicheng, it is estimated that there is no way to repair it.
Even in Saskatchewan, there is no 4s shop.
It is estimated to be shipped back to the mainland.
Or find a local non-4s store.
The premise is...
Able to reach Sacheng smoothly.
How to do?
It is still four shifts today. Ask for a recommendation. Thank you.
