Fortunately, Zhong Bai didn't hesitate to sit next to Yu Dongfeng, and patted him on the shoulder with his hand by the way, and said in a low voice: "Don't worry, it's just a formality, I'll answer any questions they ask, just prepare the cigarettes and coffee here......"

"Hey, hey, I'm good at this!" As soon as he heard Zhong Bai's arrangement, Yu Dongfeng suddenly felt a lot more at ease.

DWX35-180/100X hydraulic strut In Zhong Bai's opinion, it is definitely the latest hydraulic strut technology in the world!

Although it is not clear the origin of the two audit engineers, Brown and Ricky, Zhong Bai knows very well that the hydraulic strut commonly used in the world does not have the ability to integrate more than two technologies, and the most powerful point of DWX hydraulic strut is that it perfectly combines W (external injection type) and X (suspension technology)!

It sounds like a combination of two terms, but only those who really understand the industry understand how difficult it is to combine them in today's underground mining support system!

Sure enough, Engineer Brown, who was mainly responsible for looking through the patented material, only looked at a few pages before his brow twisted, and the first question seemed a little impolite.

Brown raised his head, stared at Yu Dongfeng with very puzzled eyes, and said the doubts in his heart: "I want to ask, the suspension technical principle of this design has never been applied in the underground mine support system, why do you think it can be used in hydraulic struts?" In particular, how can you guarantee its security? You know, if the miners in the underground mine are not safeguarded, their lives are in danger from the moment they go down the mine! ”

Bridget also took advantage of the situation to cast her eyes, but Yu Dongfeng unhurriedly followed Zhong Bai's previous "instructions", took out a box of cigars from his arms, opened it by himself, and "fed" one to the two engineers opposite, before slowly and leisurely using a few simple English words that he urgently learned from Zhong Bai and said, "liste."

to him. ”

In the face of this professional question, Zhong Bai of course also chose to use the most concise and professional language to answer: "DWX type pillar adopts the principle of plunger suspension technology, so that the hydraulic suspension force acts directly on the top cover through the inner cavity of the pillar live column, and the hydraulic suspension force shares about four-fifths of the working resistance of the pillar, so that the force of the live column in the axial direction is only one-fifth of the working resistance, compared with the traditional pillar technology, it greatly improves the support height and bearing capacity of the pillar. So I don't need to talk about stability and security, right? I've proven this in the material with a detailed data model, you can take a look. ”

Rao is Brown is well-informed, and he has never encountered the other party explaining all this in such a firm and relaxed tone when a new patent application is being reviewed, he couldn't help but gasp, and was speechless for a while, so he had to touch Ricky next to him and asked in a low voice: "I can't see much of this model, your opinion?" ”

Because Brown and Ricky actually have a clear division of labor, Brown is better at overall theory and design ideas, and Ricky is more proficient in specific drawing, data, formulas and other calculations, so the combination of the two is just right.

Ricky immediately pulled out the detailed design drawing focusing on the plunger suspension design from a stack of design drawings, carefully copied the data on it, and called up a set of data combinations of the most ordinary underground coal mines from his mind, and then combined them with this scene for real-time calculations.

It has to be said that in this era when electronic computers were not yet commonplace, this kind of instant calculation completely relied on the mathematical ability of the individual.

Fortunately, Ricky took industrial mathematics at the bachelor's level, but even so, this set of things he had never seen before still took a lot of time when he first calculated, and after half an hour, Ricky cautiously said: "After my calculations, based on the model of the common European medium-sized underground coal mines, the new underground support system formed by using this new technology has a safety guarantee rate of 9......"

"Between ninety-two and ninety-five percent, I'm not wrong, right?" Before Ricky could finish speaking, Zhong Bai had already taken the lead in announcing the answer.

This precise answer naturally made Ricky's blue eyes widen again!

Ricky asked incredulously, "You...... Have you already done your calculations using the European model of a medium-sized underground coal mine? ”

"It's not a difficult thing to do, Ricky." Zhong Bai smiled slightly: "If I told you that I didn't think about it beforehand, but expected this result when I saw you write the first line of the calculation process, would you believe it?" Or do you think I'm bragging? Or is it some mysterious magic from the East? ”

"This ...... I'm honestly a little bit unconvinced. Ricky didn't expect Zhong Bai's answer to be so out-of-the-box, and he was dumbfounded again.

But Zhong Bai didn't explain anymore, he knew anyway......

This data is absolutely correct!

Because in the demonstration scheme after the DWX technology came out in the previous life, of course, data demonstrations in this regard have also been made, and one of them is the demonstration of the environment of the underground mine of medium-sized coal mines in Europe, Zhong Bai just said this correct conclusion.

But Ricky couldn't understand why he had worked so hard to calculate the data he had obtained for so long with his pen, and the young man from China opposite could say it casually while smoking and drinking coffee?

If Director Bridget hadn't mentioned to the two of them on the departing plane that the magical scene that happened during the last on-site patent audit in Bern - which was also questioned by the audit engineer, and Zhong Bai directly asked them to come up with on-site data and photos to corroborate it, I'm afraid that Ricky would really be unconvinced today and have to argue again.

Because Zhong Bai was exposed to such a professional data problem at the beginning, many of the subsequent prediction links were not as long as the two engineers expected.

In short, to sum it simply, the review stage of theoretical materials, which was originally expected to take at least a day to complete, was completed in just over three hours, and it was even in time for today's dinner.

"Zhong, you're still as productive as you were last time." Bridget smiled and stretched out her right hand to shake Zhong Bai, but then changed the conversation and said: "The theoretical aspect has been approved by the audit engineers, and we can also sign a patent agreement on the spot, but ...... In the future, if there is a big difference with the theory in practice, the Swiss Patent Office also has the right to invalidate the patent at any time, do you have no objection to this? ”

Zhong Bai nodded calmly and said, "Of course I have no objection, in fact, even if Director Bridget doesn't say this, I originally have another proposal." ”

After speaking, Zhong Bai glanced at Yu Dongfeng, and the goods immediately entered the state.
