Li Lianxiang responded to Qin Shiwei's surprise with the laughter squeezed out of his throat and eyes, and his pride was overflowing.

Qin Shiwei looked at the thin two pieces of paper for three minutes before he raised his head and exclaimed: "The combination of your three devices is really good, there is no use of anti-wear and corrosion-resistant tubing, but the relative carburizing and quenching tubing wear ratio is 2.5, and the relative ion carburizing tubing wear ratio is 0.5."

It is equivalent to using three gadgets to increase the Rockwell hardness of the tubing to more than 65. ”

He went on to comment: "The design is clever and inexpensive, and it has the style of Czech industry." ”

Su Cheng nodded secretly. To describe this anti-deflection system as Czechoslovakian industrial design, it is surprisingly apt to describe it as a Czech machine gun, with a design that was ahead of its time to bring stable 68 Chapter 68 (monthly pass) performance, low cost and simple construction. Qin Shiwei can say this, and his ability can be seen.

Qin Shiwei walked to the iron frame with unfinished intentions, looked at the workpieces one by one, and then said: "Your anti-eccentric wear system, I think it can be compared with imported oil pipes, if you compare it, you can save a lot of money." Yes, who designed it? I must meet such a designer. ”

Director Yang did not hesitate to make way for Su Cheng.

Qin Shiwei said in surprise: "Director Su still understands oil extraction machinery?"

Su Cheng's face was not red and his heart was not beating, and he said, "There will only be a little bit of medical treatment." ”

"That's also very remarkable, I thought your major was geophysical prospecting, and it was not easy to learn both at the same time. ”

Su Cheng was forced to be anxious, so he had to say unashamedly: "Isn't Dean Qin also an expert in mechanics and exploration..."

"Technically, it's very rare to see people at my level. If he is proud, Qin Shiwei said it very freely, and said: "I also loved to draw such designs in my early years, and I learned from the Soviets." At that time, when I went to school in Beijing, I was a bitter person, I checked the information late and night, and I couldn't sleep overnight. I'm not good at Russian, and I often ask for a word, a word to look up in the dictionary... When Director Su went to school at a high level (asking for a monthly ticket), it was much more comfortable. ”

Director Yang wasted no time in saying: "Our Director Su graduated from Peking University. ”

"Hey, Peking University still has a petroleum major?" Su Cheng said abruptly, "I graduated from the Department of Chinese at Peking University. ”

Qin Shiwei, who was talking endlessly, was finally speechless, his eyes widened, and the muscles in his arms bulged.

Su Cheng secretly sighed, Dean Qin was born 30 years early, otherwise just by relying on his figure, he would have to be pushed back by the girls in the school 35790 times.

Holding a dozen pounds of workpieces to do a human wear experiment, is not equivalent to a dozen pounds of dumbbells flat push, if anyone has the patience to do 117,077 times, the muscle mass can also be as hard as a stone.

Director Yang coughed lightly and said with a smile: "Dean Qin, look, did you give us the certificate?" ”

"Okay, Xiao Wang, open the certificate. Qin Shiwei helped unload the workpiece, and said with a smile: "You guys, I recommend it to you, there are really a lot of partial grinding wells in our oilfield." How about adding 20% to the cost? Now that the enterprise is in a recession, many of them are adding 10%, is the cost of this eccentric grinding system 300 yuan?"

He is a pure state-owned enterprise. In the era of planned economy, the superior calculated the cost and added a profit of 10% or 15% to become the final selling price of the product, and if there were no other changes, this price would never change. So a strange phenomenon is formed, the longer a commodity is produced, the lower the cost, and the higher the profit of the enterprise. On the contrary, the new product has the lowest profit ratio. It is not to blame that enterprises lack the awareness of innovation.

On the side, Li Lianxiang was embarrassed all of a sudden. The design drawings were drawn by Su Cheng, and the design of the process flow was made by him. Qin Shiwei calculated the cost through the design, and felt that it should be 300 yuan, but the actual cost of what he did was 360 yuan, doesn't this mean that the cost of his work is too high.

Su Cheng said with a smile before Li Lianxiang spoke: "Dean Qin has calculated that the price of forging steel blanks is hundreds of yuan, in order to launch this set of equipment, we have specially updated the assembly line and lathe equipment, if the sales volume is less than 10,000 sets, the cost of each piece is about 1,000 yuan." This does not take into account the manpower and machine hours used in design and experimentation. ”

"1000" Qin Shiwei's face turned cold: "How much do you want Lou?"

"To achieve the same level of anti-wear, we need to equip an anti-wear sucker rod of about 2,500 yuan, and we only need 80% of the price, 2,000 yuan. Moreover, when it expires for replacement, or accidental damage is mostly the centralizer and rod wear reduction coupling, the maintenance cost is only half. Su Cheng said and took a breath and smiled, "And, most importantly, the use of our anti-deflection system does not prevent customers from continuing to use anti-wear sucker rods on some special oil wells to achieve better results." For example, our anti-eccentric wear system and anti-wear sucker rod of the same level only cost 4,500 yuan, but the effect is better than that of a sucker rod coated with a hard composite resin coating of 10,000 yuan. ”

Qin Shiwei's face was a little foggy, but it was still not good-looking, and he said sarcastically: "Your last sentence is a lie at all. Manufacturers who make anti-wear sucker rods can also use their sucker rods with your pipe rod anti-friction couplings, centralizers, and weighted rods, and they are more flexible. ”

"They can be fitted with the old weighted rod and centralizer, but our new model works better, as you can see from the tests. In addition, they cannot be equipped with our pipe rod anti-friction couplings. There are patents. ”

"There are patents!" Qin Shiwei was indignant and said: "If you have a patent, you can sell it for 3 times the profit?"

What kind of person is 300% of the profits? You are still a state-owned enterprise......

"We are a joint venture. Sioux corrected quietly. If it were someone else, it would be in Qin Shiwei's hands, and the cost would be obvious at a glance, and 3 times the profit would indeed make people quite shy.

However, it is only shy.

"Are you a joint venture?" Qin Shiwei repeated.

Sioux City nodded.

"This" Qin Shiwei was a little confused, and whispered: "Joint ventures should also earn reasonable profits, yes, reasonable profits." ”

Su Cheng shook his head and said, "Dean Qin, you're not right here. Do you think that our anti-deflection system can save the country more than 20,000 yuan, and there are 20,000 oil wells in production in Shengli Oilfield alone, saving 400 million yuan, and we earn 10%, is it a reasonable profit?"

Qin Shiwei nodded blankly, and suddenly became angry: "You still want to earn 40 million!" !!
