Chapter 93 Marine Diesel Engine

Two weeks later, the 190 diesel engine for the test was removed from the production line.

The 190-liter 500-horsepower diesel engine is quite a big guy, and it requires professional handling equipment to carry it down. Put it outside, it's like a movable board room.

Compared with the diesel engines previously produced by Jinan Power Plant, the 190 series has made great progress in power and energy consumption. Of course, it still has a lot of room for improvement. In the next 20 or even 30 years, the 190 series of improved D-type and improved H-type are still on sale. Liu Qiu, as a big player, is this 190 diesel engine.

In the memory of Sucheng, after PetroChina reinvested its capital into Jinan Power Plant, they had tried several new products, but the Jedi still fought back against the 190 diesel engine. Due to its reliable performance, it once forced foreign diesel engine brands to Liangshan, and finally had to rely on bundled sales to survive.

In terms of product design, Liu Qiu's 190 series diesel engine is a masterpiece. The average effective pressure, power, speed, maximum burst pressure, cylinder diameter stroke ratio, partial load minimum fuel consumption rate, and other indicators have been improved to a certain extent compared with similar products. The most rare thing is that he also considered The needs for improvement in the future have consumed a lot of energy to reserve space. This is the fundamental reason why the 190 series can be improved for 30 years.

Although Liu Qiu's later works are more advanced, there is no such perfect work as 190.

Su Cheng thought: 3 years of laid-off experience may have made his life difficult, but it has sharpened his spirit and body. After success, how can a successful designer have 3 years to do design, 3 years to think about it carefully and make some improvements.

I just hope that more than a year of accumulation is missing, Liu Qiu's 190 series. Don't change too much.

"Su Dong? Test the machine?" Chen Zunian shouted. He is still the director of Jinan Power Factory, and Su Cheng, the owner of the factory, has become Su Dong.

"Test the machine." Su Cheng restrained his spirit. Watch the diesel engine start.

The dull roar. It's exciting.

Liu Qiu and others stood in front of the instrument and monitored the data.

After a while, Su Cheng asked, "How's it going?"

Liu Qiu rubbed his messy hair and took two steps back. He said, "The situation is very good, if it passes. If we work overtime, we can produce 1,000 units this year.

"Oh, show me the drawings." Su Cheng only knows a piece of fur. Just ask Liu Qiu to explain it to him.

Although it is still more than ten years away from Da Niu. But Liu Qiu is still very old-fashioned to explain his works.

Seeing that he had considered the reserved space, Su Cheng nodded secretly and cut out the details, which can be used on the second and third generation models. Don't worry.

After all. They have produced 190 diesel engines more than a year in advance.

"Next, what do you think about the improvement of diesel engines?" Su Cheng asked Liu Qiu directly.

"I think. Improving power is the primary consideration..." Liu Qiu held his head high and said a few words very clearly, which was obviously already prepared.

If he combed his hair a little, his appearance might be better.

"Power is indeed a problem, and 500 horsepower is indeed a little less. However, the current diesel engine is not easy to sell. Su Cheng didn't want to attack Liu Qiu's enthusiasm. He said, "Expanding the use of diesel engines is more important than the production of diesel engines. Here, you should pay more attention to it."

"Extended use?"

"The diesel engines we are producing now are all used in construction sites and small power plants. Now the oil fields are waiting to be separated, and the big orders have stopped, so we can't count on them. For the remaining coal mines and metal mines, the amount of industrial and mining vehicles is too small, and generally they will not buy a 190 diesel engine. Therefore, you have to consider several improved diesel engines so that they can be suitable for more places.

Liu Qiu was dumbfounded and asked, "Where else can this thing be used?"

He is engaged in product design, not industrial design. He really doesn't care about the use and so on.

"How about the ship? Marine diesel engine. Nowadays, coastal fishing boats are very profitable, and transportation is also very profitable. We provide them with better and cheaper diesel engines, and the market is definitely good. Su Cheng found one of the final assembly drawings, scratched two with his nails, and said, "The main structures such as cylinder diameter, stroke, cylinder center distance and so do not need to be changed, as the connecting rod, crankshaft, piston, etc. However, the lubrication system and oil bottom shell need to be modified to avoid oil spilling or oil pump suction in The intake, exhaust and cooling systems should also be redoed to adapt to the environment on the ship..."

Liu Qiu looked carefully, holding a pen in his hand and scribbled on the notebook.

Before Su Cheng came, he had done his homework. Marine diesel engines are an important direction for the development of diesel engines. China has few ships, especially since the 1970s, the tonnage of ships in China has not been as many as that of Bao Yugang, the king of Hong Kong. But this phenomenon will change very quickly.

The first thing the country needs is inland river boats and offshore fishing boats, and then heavy-duty cargo ships and professional ships.

is just adapted to the improvement of the diesel engine.

Su Cheng briefly said what he thought. Chen Zunian listened with a learning mentality and asked, "Then who should we buy a diesel engine?"

"Shipyards, even private fishermen, whoever can get 50,000 yuan can take away our diesel engine."

"50,000 yuan? Our cost is more than 50,000 yuan (bookstore www.shushu5.com is the fastest update www.shushu5.com). Liu Qiu jumped up.

Su Cheng suppressed him and said, "I found someone to calculate the cost of materials, which is 50,000 yuan. The problem now is that our production cost is too high. We have to find a way to reduce costs, not too expensive.

"We used to sell it for 150,000 yuan." Liu Qiu muttered.

"Maybe in two years, we can still sell it for 150,000 yuan, but not now." Su Cheng thought that the cost of diesel engines in the future has fallen and fallen for a long time, and the price will remain unchanged for 10 years and 20 years, that is, the end of enjoyment, and it is time to pay off the debt.

He raised his chin and asked, "How long can you change the marine diesel engine?"

"It will take a few months." Liu Qiu was not in high interest and asked, "Isn't the ordinary diesel engine produced?"

"Production is determined according to the sales volume." Su Cheng knows that there will be no sales of ordinary diesel engines in a year. Count on the soon-to-revocation of the Ministry of Petroleum, or PetroChina, which is not yet in power. It's all unrealistic.

Chen Zunian is a little nervous. They have been out of the market for two or three years. It used to be a planned economy. There is a natural fear of the market economy.

After saying two more words, Liu Qiu was all depressed.

Only then did Su Cheng realize that he had hit Liu Qiu's confidence. I can't help comforting him again, thinking: the great of the future. It seems that he doesn't care about anything. Who would have thought that he is also a fragile young man now... Uh-huh. He is a vulnerable middle-aged man.

Liu Qiu touched his messy hair. He said unhappily, "Su Dong, you are the boss. I'll listen to you, but there is nothing wrong with the design of my diesel engine, as long as it is produced. Don't worry about the lack of market... We should still do our best to produce it."

2 years later, the situation may be like this. Su Cheng shook his head secretly: there was no order for the oil system. The annual output of 1,000 diesel engines is even worse than the cost of sending 200 pumping units for free.

However, this kind of judgment on the market is very boring to argue, and it will not get an accurate [answer] case.

Su Cheng looked at the drawing and said, "You just said that there is no problem with the design?"

He suddenly remembered a classic mistake.

Liu Qiu was at a loss and said "not bad" with a stiff face.

Su Cheng pulled a drawing, clicked on the right side, and asked, "How to explain it here?"

"This is a security device." Liu Qiu looked up and said, "This is to avoid low oil pressure, and it also designs the function of overspeed automatic parking. In addition, if the oil temperature is high and the water temperature is high, it will automatically alarm. There is a butterfly valve on the intake pipe of the diesel engine. Once the emergency stop is stopped, the butterfly valve is closed, and the air will be cut off.

"However, closing the butterfly valve, the residual air will change the pressure of the cylinder. Isn't the pipeline here at risk of backflow?"

Liu Qiu looked puzzled, and his head circled twice before he gently said "ah".

This is a classic small error on 190, which occasionally occurs, but is always misunderstood by users as a misoperation. After the release, all the 10,000 diesel engines in use were replaced on a large scale, and Sucheng had also seen it.

Liu Qiu's whole head fell on the drawing, no matter whether he tried his best to produce it or not.

Chen Zunian thought that Su Cheng was at the banquet that day, and the "20 million yuan" he promised to Director Ding was itchy, but it was not easy to ask.

Jinan Power Factory is a wholly-owned company in Sucheng. The investment must be invested, but Chen Zunian is not sure how much money Sucheng has.

After a delay of two days, Su Cheng saw that the production was on the right track and returned directly to Dongying. Chen Zunian had to hold back his words.

He is actually quite satisfied with the current situation. Although half of the workers are sent to Dongying to produce diesel engines, and only half of them can work in Jinan, it is much better than the fate of all laid-offs to collect living expenses.

Su Cheng returned to Dongying, but fell into the wine pond meat forest.

Last year, he was just a college student with the title of Peking University and did not have the opportunity to accept and launch a banquet.

Nowadays, the identity is very different.

In addition to the cadres who are still in the Beijing Running Department, the big and small brains of Shengli Oilfield have known about Sucheng and Dahua Industry, which is a supplier to foreigners.

Anyone who can get a little relationship will try to make an appointment with Su Cheng. Among them, there are mainly office directors such as Wei Kong and people such as the director of the oil production plant.

Su City has never been in contact with such a battle. He drinks dizzy every day, but he can't go. Fortunately, after practicing the amount of wine, I drank a catty and a half of Maotai slowly, so that it didn't collapse immediately...

Moreover, it is a good life to be able to eat and drink in the 1980s. Su Cheng is a bachelor. Occasionally, he can pull Shu Lan to press the road. He has to thank the society for his tolerance. Let others cook or something. Don't think about it, and "God's reason is not allowed"!

Steak and other things, you will always get tired of eating too much. On the contrary, in the oilfield canteen, there are always one or two famous chefs, with a salary of about 100 yuan, cooking a plate of famous dishes for 30 yuan - this salary is already very high in China.

The person who invited the guest knows that Sucheng likes food. If you look for it casually, you can borrow a new cook. Sucheng drank from the oil production factory to ten oil production. Lu, Sichuan, Guangdong, Fujian, Jiangsu, Zhejiang, Hunan and Anhui almost ate...

On this day, as soon as Qu Guoda, the director of the oil production factory 2, sat down, his men chased him in.

"There is less oil." When the person came only said one word, Qu Guoda rushed out and cursed: "These fuel consumptions are not going well in the New Year."
