Chapter 1665： The cost of developing industry

Originally, the development of the human oil industry originated from the extraction of kerosene. However, this does not mean that Marin has created a kerosene lamp and mastered the oil refining technology, which will enable the North Sea oil industry to take off quickly.

The main reason is that there is no technical support from the whole society. After all, in 1859, where the modern petroleum industry originated, human steam engine technology has matured long ago, and too many mechanical experts have emerged. Therefore, after the oil is extracted, it can be quickly put into application. In addition, the technology for oil exploration and extraction can also be developed rapidly.

But in this era, I am afraid that only the traversal of Marin will know what is the oil industry. Even Leonardo da Vinci, the world's smartest, knows nothing about the oil industry.

In particular, petroleum exploration and drilling technologies are subject to technical constraints, and it is difficult to achieve great development. Even if Marin developed the rotary drilling technology, he could only drill shallow oil wells 100 meters deep. This technology, the vast majority of future generations of large oil fields can not be developed. The oil wells that can be developed are those places where the limited oil seedlings are exposed to the surface, such as Titusville, Galicia, Baku, sulphur pits, extensions ...

However, the output of such shallow wells is not high, and cannot meet the huge demand of kerosene lamps. Therefore, in the early days, the application of kerosene lamps will not be very wide. Of course, until Beihai has trained several generations of mechanical engineers, and the technology has gradually matured, it can drill deeper wells and get more oil.

In fact, in Marin's memory, the 12-horse Changchai walking tractor bought by the old horses of the previous life could also be copied by a craftsman. After all, vulcanized rubber is now available, and as long as you spend some time and let the craftsmen go all out, you can still copy that single-cylinder diesel engine. At most, it is because of the rough technology that often causes problems with the machine, just like the current watt-like steam engine.

But the biggest problem is not here, mainly due to diesel supply. With the oil production of only one barrel per day in the Galician oil field, the refined diesel can be used for a walking tractor for up to one day. This is calculated according to the maximum diesel refining ratio of 30%. But it is good to use Marin's workshop-level technology to extract 20%.

Even if a one-handed walking tractor only drives 8 hours a day, it can supply up to two or three tractors. As a result, what can this change? The supply capacity of two or three single-cylinder diesel engines ... well, it is still useful, at least, you can accumulate technology ...

So, Marin began to organize a large number of craftsmen and began to copy the 12-foot walking tractor in their family in the previous life ...

Why did Marin insist on 12 single-cylinder diesel engines when diesel is extremely scarce? Not for wide application, but for its speed!

Yes, no matter how bad the single-cylinder diesel engine is, the speed is much stronger than the steam engine. The current watt steam engine of the North Sea country only has a speed of more than 50 revolutions per minute. This speed is not much different from a hand-cranked machine. The single-cylinder diesel engine is different, Marin remembers that his previous Changchai 12 horses had a speed of 500 to 800 rpm!

This speed, in large-scale industrial production, may have little application value due to lack of oil. However, if it is used to drill the barrel ...

Yes, Marin thought of the drill barrel. For a rotary drill, the faster the speed, the stronger the penetration. If a single-cylinder diesel engine with a speed more than ten times faster than the current Watt steam engine is used, the efficiency of the drill barrel will be greatly improved. Even, can also be used to drill the barrel ...

No more, as long as there are so few single-cylinder diesel engines used to drill the barrel, it is basically enough. After all, the size of the Beihai army is just like that. The demand for barrels is not high, and tens of thousands of barrels are enough. Unlike later generations, some of the rifles installed have a number of tens of millions of levels, and the number of AK47s even exceeds 200 million ...

In addition, the single-cylinder diesel engine is also very good for drilling wells. In the past life, the country's drilling rig used a steel frame with a small diesel engine on it, which pushed the rotating drill bit down. Marin's authentic oil drilling machinery has not been seen, but this kind of drilling rig used in the country is still seen. Although this drilling rig can generally only drill a few tens of meters in depth, it was sufficient for drilling shallow oil wells in the early days. The most important thing is that its efficiency is much faster than the traditional traditional drilling technology. Marin remembers that the well-drilling machine that was used in the country in the past life, it is no problem to drill two irrigation wells a day. If you use the ancient gravity hard drilling technology, according to the technology of Zhuojing Well, it is estimated that it takes six to seventy days to drill a salt well with a depth of 100 meters ... This efficiency is incomparable ...

Of course, all this is the ideal state. But the reality is ...

Marin finally directed the craftsmen to imitate the 12-piece Changchai single-cylinder diesel engine. As a result, during the trial operation, there was a problem with the design of the bayonet of the crank (the Malian memory did not pay attention to this small detail), the crank did not It can be taken down in time, and then, when the diesel engine turns, the iron handle is flying out and directly kills a close craftsman ...

The next day, during the trial operation, the huge flywheel of the diesel engine flew out directly because of the weak riveting ...

Fortunately, this time everyone was mentally prepared, and a bunker was added, with no casualties.

In addition, the transmission belt made of the first generation of vulcanized rubber made by Marin seems to have unstable quality and wear resistance. No, it suddenly broke after running for two days ... Fortunately, Marin has sisal fiber as a backhand. After changing to the transmission belt woven with sisal fiber, it really works better ...

Seeing these unpredictable circumstances, Marin was also frightened. It seems that the backwardness of society's overall mechanical technology makes many problems that Marin had never seen in his previous life after the machine was manufactured ~ www.novelhall.com ~ Moreover, they are all low-level problems that Marin did not expect.

For the sake of safety, Marin still left these issues to the craftsmen. Moreover, this process is also the process of growing technology.

However, in order to prevent accidental death, Marin let those craftsmen not only place bunkers when testing single-cylinder diesel engines, but also close-up craftsmen should wear a full set of plate armor as protective clothing to avoid accidental death by the machine ...

In fact, Marin did not know that when the later Xinhua Kingdom was founded, the machinery industry was developed everywhere. Even with the guidance of Mao Zi experts, there were still many accidents. In every machine accident, someone may be injured or even killed. For decades, I do n’t know how many workers in machinery factories have broken their fingers or their entire hands, and the whole person was killed by machinery ...

There was no way. At that time, the country was newly created, and the foundation of the machinery industry was equivalent to no, and it was not much better than Marin. The only thing better than Marin's situation is that there are mature foreign theoretical guidance, as well as many advanced prototypes abroad for reference. Rao is so, there are still many workers in Xinhuaxia because of machine problems, or improper operation, there have been many accidents, causing many casualties. Marin has read a report in later generations, saying that in Wuhan alone, the number of casualties from work-related accidents has reached 50,000 in a few decades. Among them, the highest proportion is the disability of the limbs (mainly the hand) ...

In our later generations, many people admire the eighth-level mechanics who were super skilled in the past decades. But I don't know that these eight-level workers are the lucky ones who survived repeated accidents. Unfortunately, people basically lie in the cemetery. Only after summing up the experience and lessons of the dying workers, did the eight-level workers gradually grow into the mainstay of national industrial construction. And this is the cost of exploring and developing the machinery industry ...
