In fact, the so-called courses that Professor Wang Defa is taking now are just popular science courses with ulterior motives. Pen % fun % Pavilion www.biquge.info

His sinister intentions are obvious, and he wants to pave the way for the driving force of Shangma Hongshuixi Industrial Park.

They do have to use water, and they may even use animal power.

For this reason, they all bought a full eight donkeys, which caused price fluctuations in the livestock market in Lin'an County.

The city officials who collect taxes in the market all call it a big deal that has not been encountered for many years, and it is actually not worth the price of a small mirror.

This is not to be flaunted.

But these prime movers are just some cover-ups, and in the core prime mover, they can only use steam engines.

Song Ziqiang once suggested using a big flywheel diesel engine directly, and he said with a smile: "You can burn gutter oil for that thing, it's very useful!" Pumping, milling, crushing, bringing a generator and it will generate electricity, loading it into a car and it will drive, the leather is durable, no need for a little electronic equipment! I can disassemble and install it with my eyes closed, can you believe it? ”

Wan Shida was about to die of laughter and said, "Boss, do you know how much fuel is lacking at this time?" They don't focus on stir-frying now, they only like steaming, boiling, and the like, why? Lack of oil......"

However, during the Southern Song Dynasty, there was a shortage of vegetable oil in all parts of the world throughout the time and space, and the reason does not need to be explained.

They have observed that the main products sold in this county town of Lin'an are sesame oil and animal oil.

Before the Song Dynasty, most of it was sesame oil, and there were few records of other oils, which was related to the oil yield, but in fact, it was mainly related to the driving force.

Soybeans, this time and space have long been available, and the yield is okay, but where do they have the ability to squeeze soybean oil?

It can only be said that sesame seeds and other hemp seeds are easier to squeeze.

Of course, technology is always going to grow, but it's going to be very slow.

Fortunately, after the Song Dynasty, the number of oil crops used for oil extraction began to increase.

Zhuang Xuan of the Northern Song Dynasty recorded in the "Chicken Rib Edition": "The oil passes through the four directions, and it can be eaten and natural, but flax is the top, and it is commonly called fat and hemp." Hedong (today's Shanxi) eats ** oil, Shaanxi eats almonds, red and blue flowers, cranberry oil (rapeseed oil), Shandong also uses Xanthium as oil, and Yingzhou also eats fish oil. ”

As I just said, this soybean has a long history of planting in the Great Song Dynasty, but it is not a raw material for oil extraction during this period, because the oil content of soybeans is low on the surface, only 16~19%, and in fact, the crushing capacity is limited.

Even in the Ming Dynasty a few hundred years later, after they used the pressing method to extract oil, the oil yield was only 7.5%. , and this sesame seed has a high oil content, reaching 45~50%, and it is easy to press, and the oil yield can be close to 35% by pressing method.

Another kind of tung seed with a high oil yield, but the tung oil it squeezes is inedible and can only be used as fuel and paint, and the raw material output is still very low.

Therefore, except for sesame seeds, other edible oil crops rarely have an oil yield of more than 25%, which is why sesame oil has dominated for a long time.

So if you see a person selling soybean oil on the street in the Southern Song Dynasty, he almost came from the Ming Dynasty.

The oil content of peanuts is very high, about 45%, and it can also be used to extract oil to obtain a high oil yield.

But if you meet a person who sells peanut oil, then he must have been wearing it after the late Ming and early Qing dynasties.

There's nothing wrong with catching and hanging him, it's been so long, he hasn't been able to change anything, what are you waiting for if you don't hang him?

Peanuts are a plant of the Americas, which began to spread on the world's continents after Columbus discovered the New World.

The peanut was introduced to China in the 16th century, when it was still slow to spread from the coast to the interior, so peanuts were still a rare feast food until the end of the Qianlong period.

Like corn and chili peppers, this time and space cannot be found in the Great Song Dynasty.

Here I can only ask a writer with a pen name and surname Jin, hehe, except for the traverser, everyone can't eat it, where can I buy it casually in a small restaurant?

By the way, there is also the common bean of broad beans, which only appeared at the end of the Yuan Dynasty.

But in any case, the variety of edible oil eaten by the people of the Song Dynasty increased, and their love for fried food was unprecedented.

Shen Kuo recorded in "Mengxi Writings": "Today's northerners like to fry things in sesame oil, no matter what they are, they all fry them in oil. "I really want to fry the sesame seeds in sesame oil before eating.

This hobby was probably also transmitted to the surrounding countries, and the nomadic countries were estimated to have enough animal oil to eat, so they often asked the Song Dynasty for it.

The Great Song government had to pay annual tribute to the Liao, Western Xia, and later Jin to maintain peace, and according to the History of the Song Dynasty, among the tributed products was oil.

Hong Hao, who was an envoy to the Jin State during the Southern Song Dynasty, recorded such an incident, the Jin State treated the visiting missions of the Song Dynasty, in terms of living treatment, wine, meat, noodles, and rice were supplied to everyone, but only the deputy envoy and above were supplied with oil every day.

Look at it, in the so-called powerful Jin country at that time, oil was such a precious living material.

As for what method to use to extract oil, there are only a few words in historical materials such as "frying coke and pressing to get raw oil".

In fact, this is the method, so even in the Southern Song Dynasty itself, it is not the master of the rich production of edible oil.

Therefore, if you want to use edible oil as the fuel for the prime mover, not to mention the cost, the supply is a problem.

Song Ziqiang had to smile dryly at the time and said: "I'm a technical uncle, not a supply uncle, can't I keep it for emergency backup power when the time comes?!" ”

"Of course you can," said Wanshida...... But you have to think about wasting wormhole energy when traveling through time. ”

Song Ziqiang was proud at this time, and said: "You give me an ordinary machine tool, milling machine and grinding machine, medium carbon steel materials, and I can process one for you, no need to bring one." ”

It's a good way, but is there a better way?

At that time, Song Ziqiang began to get serious, and at that time he saw that Zhang Guoan and his wife were extremely serious, and their faces were serious, so they also took the initiative to participate in helping to design a development system of industrial power.

They determined that charcoal was used as the industrial power fuel for the initial development, but there was no way, there was no coal production around Lin'an County, and the entire Zhejiang region was a coal-poor area.

Maybe there are small coal kilns? But only by waiting to travel back to determine the address, you can only set the charcoal first.

But charcoal in this time and space is not cheap, and it is much more expensive than coal, what should I do?

Song Ziqiang said confidently: "I'll give you a few machine-made charcoal machinery, and make use of the huge amount of straw and branches that are easy to get here, and even the peanut shells and corn cobs after the development of agriculture in the future, so that there is no shortage of raw materials."

I designed the machine to be a two-stage compression process of spiral preloading and piston stamping, so that it does not hurt the mold and saves power.

Besides, the heat production and refining resistance of the machine-made charcoal are close to those of medium coal, and the sulfur content is very low, which can bring down the price of this charcoal at once, and the key is that it can be supplied for production.

I don't even know how many sets I've taken over in that world, and I'm clear. ”

Wu Dapeng said: "What do you want so much charcoal for? We can't even think about selling charcoal, right? ”

Song Ziqiang sneered and said, "Don't you understand, right? We can also get two motive forces at once...... Pots and gases! ”

Song Ziqiang first introduced the pot camel machine.

This pot camel machine has its own characteristics, it is a boiler and steam power engine connected together, some are equipped with wheels, can be moved, can also be fixed.

The pot camel machine is very useful, it can drive waterwheels, generators or other kinds of machinery, with coal, firewood, oil and other fuel, suitable for rural use, especially suitable for this time and space of the Great Song Dynasty.

The pot camel machine is matched with the water pump and water wheel for irrigation and drainage; Matched with generators to generate electricity and provide electricity; And it can directly drive all kinds of work machinery in threshing, rice milling, oil extraction, sawing, food processing and machinery manufacturing.

It is a compact integral power unit that places the steam engine on or next to the boiler, and forms a compact integral power unit with auxiliary equipment such as pumps and valves.

The steam from the boiler enters the steam engine and expands in the cylinder to do work, so that the spindle rotates and outputs mechanical work.

In addition, the exhaust steam after the use of the large pot camel machine can also be used as a heat source for heating, evaporation, drying and heating.

The power of the pot camel machine is generally 10~20 horsepower (1 horsepower = 735.5 watts), and it rarely exceeds 100 horsepower. There are many types of it, but the basic types are nothing more than vertical and horizontal, fixed and mobile.

The advantages of the pot camel machine are: combustible with a variety of local inferior fuels and combustible waste, easy to operate, install and maintain, reliable work, simple manufacturing, low cost.

The disadvantages are: the preparation time for ignition is long, the boiler must be kept in a hot standby state when temporarily stopped, the thermal efficiency is low, and the device is bulky.

Until the beginning of the 21st century, the pot camel machine will be used in industrially underdeveloped areas and remote rural areas, and many factories have designed and manufactured various types of pot camel machines.

However, with the emergence of a large number of small diesel engines, the popularization of power grids and the comprehensive utilization of various energy sources, the pot camel engine as an isolated power source has been basically eliminated.

Of course, in the case of tight oil supply, the pot camel machine that burns various miscellaneous materials has been technically transformed and may be applied on a local scale.

Wu Dapeng said in surprise: "Isn't this the driving force for the Great Song Dynasty...... I haven't seen it before. ”

Song Ziqiang still sneered and said, "What is this? I haven't said about the gas machine yet! ”

The gas engine is generally composed of cylinder head, cylinder block, crankcase, crank connecting rod mechanism, gas distribution system, ignition system, etc., because it needs to be linked with the gas generator, so it is mostly used in power stations and power stations as fixed power. Of course, it can also be fixed on ships, vehicles, etc., as output power.

There are many steel and cast iron used in the pot camel machine, and when the output of these two items is not much, it is difficult to supply the pot camel machine in large quantities.

At this time, the advantages of the gas machine is light, the thermal efficiency is as high as about 15%, it uses less steel, low cost, easy to handle, and the required materials can be solved by themselves, so the gas machine can become the focus of their future power machinery development.

The structure of the gas engine is similar to that of the gasoline engine, and it is divided into diesel gas engine and spark ignition gas engine according to the ignition method of the mixture.

The diesel gas machine uses coal gas as the main fuel, and the gas and air are mixed through the mixing chamber and then enter the cylinder, and when the piston is close to the top dead center of the compression stroke, a small amount of diesel fuel is injected as the ignition fuel to ignite the mixture.

Therefore, it is also a dual-fuel engine. The amount of fuel drawn is calculated according to heat, which is equivalent to 5~15% of the total heat consumption of the gas engine when it is running at full load. When the load changes, the amount of fuel drawn is generally constant.

This one doesn't suit them, don't want it.

There is also a spark ignition gas machine that ignites the mixture with an electric spark as the piston approaches the top dead center of the compression stroke.

This can be used, they think that battery technology is not difficult......

But what is also fateful is that although this gas machine is flexible and lightweight, it is not easy to operate, it is difficult to manage and maintain, and it is easy to go wrong, which requires improving the technical level of the user, teaching the technicians of the Great Song Dynasty to use the machine, and pay attention to safety when using; The machine should pay attention to maintenance, and repair it if it is broken, which requires mastering the technology of repair and maintenance; In order to solve this problem, it is also necessary to understand the construction principle of the gas engine.

Let's cultivate this slowly when the time comes, it's not too difficult.

When everyone has designed the development plan of the driving force, confidence has come.

However, Jing Jing said with some concern: "I heard you say that there are so many people, how many equipment do you have to bring here......

Song Ziqiang laughed and said, "Don't worry about it. Don't we have Zongshen car three-wheeled motorcycle, I first use its diesel power as the driving force of the machine tool I designed, process the pot camel machine, and first put the machine-made charcoal project up! Bring some grinding wheels, tools and molds and start industrialization......"

Quiet was taken aback and said, "Just rely on this little thing to start industrialization?!" ”

Wu Dapeng pointed his head and said, "And this......"

Wanshida stretched out his hand and said, "This ......"

Zhang Guoan said: "We ......"

Wang Defa said: "We need to train a group of junior technicians in advance......

To what extent, let's start with the principle of the steam engine...... It's not a few classes that revolve around this, until they have a rudimentary understanding.

and find a way to guide them to accept the gas engine, which is also Wang Defa's sinister intention in class.
