Qinling Group also has its own export channels.

That is to export to South Asia.

Over there, there is only one requirement for machinery, endurance.

The workers over there basically have no concept of maintenance. All machines are to death. Until you know it's broken.

If it's broken, say it's your bad quality. And then a whole bunch of it, it's a whole bunch of it. Yelling for a return.

The hydraulic motors are bursting, the piston pump is also finished, you tell me to return it?

It's just that those countries are still yelling all day long.

If it is not satisfactory, it will ruin the reputation of Huaxia products.

Over time, most of the Chinese enterprises did not dare to export machinery to this place.

Now, Qin Xueqing is ready to take the sword and gnaw on this hard bone.

I'll make sure you don't break it, see what you say.

You can't get it bad.

With a howitzer with a caliber of 152 mm, it will not be destroyed.

No one else can do it.

Only Wang Buan can do it.

That's right, it is Wang Buan who has such technology.

As long as Wang Buan is willing, the excavator will operate continuously for ten years without changing a screw.

Don't doubt Wang Buan's strength.

It's as if Wang Buan didn't doubt the strength of Cybertron Planet.

Transformers have gone through hundreds of millions of years, billions of years, and they are all fierce and alive. What is 10 years? It's just a snap of a finger.

"I'll go to your factory and have a look. ”

"Good. ”

What Wang Bu'an wants to see is actually the hydraulic system.

This system is divided into two parts. One is a piston pump. One is a hydraulic motor.

They are the most critical and core components of construction machinery. More important than the engine. There are many companies that can make engines. However, there are only a few that can make piston pumps and hydraulic motors.

Most of our high-end construction machinery, in these two key parts, need to be imported.

Only the low-to-mid end will use their own products.

Why?

The quality is a little bit worse.

This thing, the layman rarely knows about their existence.

However, there is a big difference between domestic production and importation.

The simplest point is that domestic ones often leak oil in two or three years. There will be no oil leakage for twenty or thirty years of importation.

It is estimated that many people who work in the engineering industry feel this way.

Of course, with the continuous improvement of the quality of domestic machinery, this feeling may have changed.

However, in the eyes of some stubborn foreigners, the mechanical products of the Huaxia brand are always inferior to Dongying. Or maybe it's not as good as Europe and the United States. Ideas are deeply ingrained and difficult to change.

What is the cause of the oil leak?

There are many reasons for this.

First, the design is not reasonable.

The second, the seal is not good.

In the latter, only a high-grade rubber material needs to be replaced. To be precise, the quality of nitrile rubber is not good.

Nitrile rubber is one of the most basic industrial raw materials. The quality of the domestic ones is not very good.

It's no problem to stick to it for a few years. Not for more than ten years.

Wang Buan's industrial park can produce a large amount of nitrile rubber every day. It's all a snap-up.

This fully shows that there are too many industries that need high-quality nitrile rubber.

The defense industry needs a large amount of nitrile rubber.

The construction machinery industry is also in large demand.

At present, it is very rare to be able to apportionment to the civilian sector. It could be just a few tons a month. Not enough at all.

Relatively speaking, the problem of nitrile rubber is relatively easy to solve.

With the gradual increase of its production capacity, it will eventually enter the civilian field.

However, if the design is not reasonable, it will be necessary to test the company's skills.

When a liquid is squeezed, how much pressure does it have, where does it work, and what changes occur?

Is it a transverse or longitudinal force?

It is often the case that something goes wrong with some details.

Actually, oil leakage is not a big problem. There is no effect on mechanical operation.

It's just that it always feels "unreliable". Together, other aspects of performance have also been pulled down the score. The overall score was lowered.

There is another problem with domestic machinery, that is, it does not pay attention to appearance.

The appearance of Dongying's machinery is clean and clean, and the paint is also very good.

What kind of technology is inside, don't talk about it yet. Purely from the appearance, it can open a grade of domestic machinery. It's comfortable to watch.

Qin Xue Group does not have a department specializing in piston pumps and hydraulic motors.

Neither did the Qinling Group.

They are all externally sourced.

High-end products are all purchased from imported parts.

For low-end products, domestic parts are purchased. These are all routine operations.

Like other construction machinery enterprises, import channels are easily affected. If you are not careful, you will be cut off from the supply channel.

Something like this is not uncommon. Once it is found that your construction machinery threatens others, others will immediately cut off the supply of high-end parts, making it difficult for you to cook without rice. can only watch others seize the international high-end market, but there is no way to do it.

Don't think you can take the individual solution. It's not that simple. Industrial confederations exist all the time.

Someone else deliberately set a threshold for you. If you want to cross this threshold, you are infringing on the interests of others. Others will join forces against you. We have suffered a lot of losses like this.

Must have its own piston pump.

Must have its own hydraulic motor.

Qin Xueqing has no way to solve these two parts.

Wang Buan made it clear that he would take over these two projects.

As long as Hu Sanniang can find enough land, he will be able to create more industrial parks and get more free robot elves.

As long as there are enough robot sprites, more parts can be produced.

However, this is not a long-term solution.

In the future, it is always necessary to build a special factory to produce.

After the brand of Qinxue Group is launched, the piston pump and hydraulic motor can be handed over to a professional factory for production.

Devise.

Inspection.

Passed without a hitch.

Piston pumps and hydraulic motors are also Transformers' strong points.

Many of the moving parts of their bodies have a similar principle. At a certain stage of their development, hydraulic technology is very advanced. Breathtaking.

In Wang Buan's mind, there is also a lot of knowledge about hydraulic systems. You can take it at your fingertips.

Of course, there are no problems with the manufacturing process in the industrial park.

It's that the capacity is limited.

Whether it is a piston pump or a hydraulic motor, the output is not high.

Maybe it's more than a dozen sets a day. A little more will not do. In other words, Qinxue Group can only produce more than a dozen sets of construction machinery every day.

If we rely on quantity to win, it is obviously impossible to meet the needs of the market. Fortunately, it is the high-end market.

There are not many units in the high-end market. The unit price is very high.

For the same excavator, an ordinary product may only cost $500,000 a piece. The profit may be as little as $10,000.

But in the high-end market, it is possible to sell for $800,000 a unit. But the profit can be more than $200,000. The two are not at the same level at all.

The corresponding cost may only be a little higher. But the corresponding profit has increased dozens of times.

No wonder Qin Xueqing's eyes were red. Who doesn't blush in this market?

However, there is no way to do it.

If you don't have that kind of technology, you just can't get it.

If it was without Wang Buan's strong support, Qin Xueqing would never dare to think about it. It's in vain to think about it.

"This is my latest design of the Vulcan series excavator. ”

"Such a bright color. ”

"That's what makes it eye-catching!"

"Oh. ”

Wang Buan was noncommittal.

He carefully studied the relevant drawings.

In terms of appearance, the construction machinery of this Vulcan series, with red as the main color, is indeed very bold.

General construction machinery is yellow. Partly white.

Red is a congenital disadvantage.

Many customers may think that you are an outlier at first sight. Again, this is not a toy. What do you do with red.

What's more, there are many flame patterns on the red exterior. It feels fancy. There may be customers who suspect that you only focus on the appearance and not the inside. And then it was vetoed again.

However, considering that Qin Xueqing is a woman. It's not a problem to make it a little more colorful.

If you can't even accept red, we won't do his business.

The key is its performance parameters.

The excavator of the Vulcan series has a bucket volume of 13 cubic meters.

It's not big, but it's not too small.

The main domestic construction machinery is in this range.

Below 5 cubic meters, they are all small excavators.

5-10 cubic meters, it is considered a medium-sized excavator.

Only more than 10 cubic meters are large excavators.

For an excavator in this category, the engine installed on the Rock 150 is just right. The power is sufficient. And it won't be wasteful.

The main hardware is fully cured, using the tertiary hard alloy produced by Wang Buan. Including all kinds of bearings, spindles, stress rods, buckets, etc., are all three-grade cemented alloys.

A very small number of key parts, such as telescopic rods, gears, etc., directly use grade 4 cemented alloy.

It can even withstand tank guns, let alone civilian machinery.

Including all kinds of rubber sealing strips, sealing gaskets, and of course, also grade 4 nitrile rubber.

What is your biggest regret?

The Rock 150 engine cannot be used for export.

This is restricted.

Wang Bu'an has been clearly informed that the Panshi series engines and Penglai series engines cannot be exported.

Unless it is approved in writing by the relevant state authorities.

This is one of the most important secrets of Huaxia. Of course, it can't be easily exported.

In fact, Wang Bu'an feels that even if some people get the Panshi 150 engine, it is completely impossible to reverse develop it.

Because the water molecule decomposer, as well as the water molecule synthesizer, are not products of the earth.

There is also the mutual conversion of nitrogen atoms and hydrogen atoms, which is not something that can be achieved by earth technology.

That's high tech from the planet Cybertron.

Without these two black technologies, the Rock 150 engine would not be functional.

What if you just let me know how it works?

You can't do the same.

Of course, there is nothing wrong with the state being cautious.

Since the Rock 150 engine cannot be exported. That's the only idea of playing a traditional diesel engine.
