Following the steps of Gu Shunzhong and Xiao Zhifeng, Zhao Guoyang and his entourage came to the finished product warehouse of the "Jinniu Machinery Manufacturing Factory".
Seeing the two factory directors bringing people over, the person in charge of the warehouse hurriedly trotted all the way over to lead the way.
"Xiao Liu, let's go and see the mine hoist imported from South Korea, you and the people below don't have to come over."
Xiao Zhifeng waved his hand at the person in charge.
"Yes, it is Mr.
Gu and Director Xiao, those mine hoists are on the east side of the warehouse, you two enter the door and turn left, you can see it at once" A group of mermaids rushed in, and after entering the warehouse, Xiao Liu, the person in charge of the warehouse, had already turned on the light switch behind them.
Gu Shunzhong was quite satisfied with this knowledgeable guy, and nodded lightly at the moment.
After less than three minutes of walking on the left road, dozens of brand-new mine hoists appeared in front of everyone's eyes.
At the first glance of these equipment, Zhao Guoyang distinguished their types of multi-rope friction hoists.
This is the same type as the first mine hoist of "SS" company, and it is also the mainstream mine hoist used in international and domestic iron mines and coal mines.
After seeing the mine hoist in front of him, Gu Shunzhong's confidence returned.
He smiled and made a "please" gesture, leading Zhao Guoyang and them to walk to these devices at close range.
"Mr.
Zhao, you see, this is the mine hoist that our factory has just imported from Hyundai Heavy Industries Group."
Turning his head and glancing at Xiao Zhifeng, Gu Shunzhong gave him a look and said, "Old Xiao, you can introduce the structure of these equipment to Mr.
Zhao and the distinguished guests."
Xiao Zhifeng nodded hurriedly and explained 1510.
"Mr.
Zhao, distinguished guests, this mine hoist is what is commonly referred to as a multi-rope friction hoist.
Its main components include spindle, main wheel, main bearing, groove device, reducer, depth indicator, braking device and guide wheel. ” "Well, we've heard of that before.
Multi-rope friction hoist, we also have a few domestic construction machinery factories can produce it."
Liu Yan opened her voice casually.
When Xiao Zhifeng heard this, he was happy: "What Miss Liu said is good.
At present, there are three or four companies that can produce multi-rope friction hoists in China.
Wuyi Heavy Industry and Pengcheng Construction Machinery Group Co., Ltd., the two giants, are among them. ” "But" Seeing Xiao Zhifeng deliberately pause, Zhao Guoyang pretended to be impatient and said: "But what Director Xiao, do you mean that your imported products are stronger than Wuyi Heavy Industry and Pengcheng Construction Machinery Group Company?"
Xiao Zhifeng smiled slightly, and said slowly: "Mr.
Zhao, which is stronger and which is weak, can you not listen to our family, right, I will probably talk about the advantages of our imported mine hoist."
"Listen up" Zhao Guoyang's eyes lit up, and he nodded again and again.
"First of all, let's talk about it in a small way."
Xiao Zhifeng touched his nose and said slowly: "Generally speaking, the leading wheel of the mine hoist is the key to its movement.
The importance of the friction liner with rope groove on the surface of the leading wheel is self-evident. ” Xiao Zhifeng said this, Zhao Guoyang is naturally very clear.
Don't talk about him, the three graduate students of Beijing University on the scene are also well aware of this, not to mention Zhao Siyan, who is the head of the product research and development department.
Of course, because of the acting, although everyone is very clear about the situation, their faces are not the slightest revealed, and they all put on a serious attitude to listen to the explanation of Director Xiao. was so concerned by Zhao Guoyang and the others, Xiao Zhifeng was a little complacent.
He said with a shy heart: "Obviously, this friction liner should have a high coefficient of friction and wear resistance and pressure resistance, and the quality of its material directly affects the production capacity, work safety and application range of the hoist." ” "At present, among the same type of products in China, the more used gasket materials are polyvinyl chloride or butyl rubber."
"These materials, although the mechanical properties are still good, but in terms of wear resistance, they are not so durable, at least, not the most reliable."
"The friction liner used on our imported mine hoist is made of polyurethane rubber material, which is not widely used in China, and Mr.
Zhao, you may not have heard of it."
Listening to the eloquent talk of this Director Xiao, Zhao Guoyang was secretly amused on the side.
Speaking of materials, there are Liu Yan and Tang Wanru, two high-quality materials born here, and what is so great about this polyurethane rubber material.
You know, their graduate thesis is about the replacement material of polyvinyl chloride.
Among them, polyurethane rubber material is also one of the preferred replacements.
Of course, at this moment, Liu Yan and Tang Wanru could only pretend to be teachable, watching this Director Xiao pretend to be an "elephant".
After talking about the material of the friction liner, Xiao Zhifeng set his eyes on a brand-new device of the mine hoist.
"Mr.
Zhao, you must have been to other construction machinery factories before, and you have seen a lot of mine hoist products, but this device, you may not see it in China."

Following the direction of Xiao Zhifeng's finger, Zhao Guoyang and Liu Yan turned their eyes to the vicinity of the console of the mine hoist.
A device resembling a scale is abruptly placed there.
This device, its own "SS" company really does not have it, whether it is Zhao Siyan, Liu Yan, Tang Wanru and others, they all show curiosity.
As for Zhao Guoyang, of course he couldn't have known what this thing was.
"Hmm, is this what kind of automatic zeroing device is there before, when I went to England to participate in a construction machinery product exhibition, I saw this kind of device on a mine hoist of Jessie Bo JCB company" After Zhao Guoyang said this, Gu Shunzhong and Xiao Zhifeng glanced at each other, both of them were extremely surprised.
Although they were convinced of Zhao Guoyang's identity as a "rich second generation" before, the other party had the money to go to England to participate in the construction machinery products exhibition of Lao Shizi, and his identity as a local tyrant was definitely worthy of his name.
It's no wonder that these two are speechless, you know, in the early nineties, the cost of going abroad once was at least tens of thousands of yuan, which was a sky-high price for many families.
Although because of the reform and opening up, the 10,000 households are gradually not so intimidating.
But casually taking out tens of thousands of yuan to go abroad to participate in exhibitions, such a family is definitely either rich or expensive.
Thinking of this, Xiao Zhifeng didn't dare to take it big, so he could only explain with a smile: "Mr.
Zhao is really well-informed."
That's right, this is another major innovation of our imported mine hoist that is different from domestic products. ” "Due to the inevitable creeping and sliding between the wire rope and the liner of the main wheel, the depth indicator deviates from the zero position when stopping, so it is necessary to equip an automatic zeroing device to make the pointer automatically point to the zero position during each stop."
After Xiao Zhifeng stopped pretending to be reserved, the speed of introduction accelerated a lot.
He points to some of the mine hoists and explains from time to time: "This is a groove device, which is used to turn rope grooves to keep the diameter consistent, which is conducive to the uniform tension of each wire rope. ” "This is a spring base reducer, which can greatly reduce the vibration of the machine."
At the same time that Director Xiao gave everyone a popular science mine hoist, Zhao Guoyang's eyes were on the mechanism of the mine hoist itself.
Because he is familiar with South Korean language, he can fully understand the instructions and product introductions on this mine hoist.
In the product introduction, one of the biggest advantages of this mine hoist was mentioned, but this director Xiao did not understand.
This mine hoist from Hyundai Heavy Industries Group is a friction hoist with built-in use.
Its structural principle is that the working machine and the driving machine are combined into one and integrate microelectronic technology and information technology, and it is characterized by the motor being installed inside the drum or friction wheel.
This integrated electromechanical whole is both a working machine and a driving machine.
Convenience is secondary, the most important thing is to save the power of the transformation, greatly improve the efficiency.
In addition, as an electric motor, it is different from the conventional structure.
This built-in friction elevator is not the stator outside and the rotor inside, but the opposite.
Speaking of which, the production of built-in hoists began as early as 1988.
The world's first built-in hoist was put into operation in the Neurumberg 7 shaft at the Germanhaus Ardennes mine.
This mine hoist from "Hyundai Heavy Industries Group" is undoubtedly plagiarized Germanic creativity in many ways, but this does not deny that it is a relatively good mine hoist.
After some observation, Zhao Guoyang has a clear idea of the general situation of this mine hoist.
Compared with the products of its own "SS" company, it still has certain advantages.
First of all, this built-in structure is beyond the reach of its own products.
However, after seeing the maximum static tension and maximum lifting angle of this mine hoist, Zhao Guoyang's worries gradually let go.
There is no doubt that in the two most important technical parameters of the mine hoist, it is undoubtedly the product of its own "SS" company, which is more competitive.
As for the benefits of the built-in structure, although obvious, it is not enough to completely crush the traditional structure.
Its stability is unknown until it is tested.
Especially this built-in structure, at a glance, you can know that it is the imitation of the "Modern Heavy Industry Group" Germanic people, and there will definitely be flaws in maturity.
In this case, its own products compete with it, and it should not be too disadvantaged.
If you take into account the factors of finished products and prices, it is even more not
