Chapter 192: Wang Jian's visit

Shang Wen looked at numerous inventions and recorded them. These inventions all need protection.

After reviewing these, Shangwen will do some experiments. Laboratory chemistry opened yesterday. This time it is physics. Electricity done in physics experiments. Shangwen believes that the sooner electricity is generated, the better. Moreover, points are needed in many places. Especially in terms of processing machine tools. It is now steam powered. But if electricity is available, the situation may be greatly improved.

The present invention cannot always stay at the stage of enlightenment, it should have taken a big step earlier.

Generator, electric motor. The first thing to do is these two. There is no problem with the generator, the problem is with the motor. There is also electricity, and batteries have to come out, but sulfuric acid is only just getting started. The chemical foundation is extremely weak.

Modern disciplines are developing rapidly, and they will soon cross-over and restrict each other. If a field stagnates. Then another area cannot make a difference. such as. In the chemical aspect, due to the backward process of obtaining sodium carbonate, the glass industry cannot develop. There is also the production of sulfuric acid. The processing technology lacks a process. There is also the power aspect. With electricity, the necessary storage equipment is lacking. The application of electricity is still in the laboratory stage. Ring after ring. One ring is one ring.

Generators are usually composed of stators, rotors, generators, end covers and bearings. The stator consists of a stator core, wire-wrapped windings, a base and other structural parts that fix these parts.

The rotor is composed of rotor core (or magnetic pole, magnetic yoke) winding, guard ring, center ring, slip ring, fan and rotating shaft.

The stator and rotor of the generator are connected and assembled by bearings and end caps, so that the rotor can rotate in the stator and cut the magnetic lines of force, thereby generating induced electric potential, which is drawn through the terminal and connected in the loop to generate current.

But its working principle is based on the law of electromagnetic induction and the law of electromagnetic force. The materials that Shangwen wants to collect are a large number of copper wires and iron cores. Also, what else. By the way, there are magnets. The magnets used today are all natural magnets. Most of these magnets are formed by high voltages that pass through in an instant when thunder in the field, or some meteorites. Shang Wen opened the collected magnet box.

"Oh, my goodness." Shang Wen was a little crazy. The collected magnets come in various shapes. Strange and strange. I don’t know that I have a quirk of collecting stones, so I just sent it directly to me without any processing. Shangwen must also perform a rough machining of these natural magnets and do it according to his own ideas. Shang Wen called someone to process these natural magnets in the same way as the cubes.

However, Shang Wen also realizes a problem, that is, it is obviously impossible to rely solely on natural magnets. Because, with the acceleration of the industrial scale, it is impossible for such a large-scale natural magnet to exist, if there is resource depletion. My goodness. There is a good show. Everything has to stop.

But humans always have a way, that is, artificial magnets. In 1822, French physicists Arago and Lussac discovered that when an electric current passes through a winding with iron in it, it can magnetize the iron in the winding. In 1823, Sturgeon also did a similar experiment: he wound 18 turns of bare copper wire on a U-shaped iron rod that was not a magnet rod. When the copper wire was connected to the voltaic battery, it was wound around the U-shaped iron rod. The copper coil on the shaped iron rod generates a dense magnetic field, so that the U-shaped iron rod becomes an "electromagnet". The magnetic energy on this kind of electromagnet is more than that of the permanent magnet. It can absorb the iron block that is 20 times heavier than it. When the power is cut off, the U-shaped iron rod can not absorb any iron block and becomes a new one. An ordinary iron rod. The invention of Sturgeon's electromagnet has made people see a bright future for converting electrical energy into magnetic energy.

In 1829, the American electrician Henry made some innovations to the Sturgeon electromagnet device. Insulated wires replaced bare copper wires, so there was no need to worry about short circuits caused by copper wires being too close. Because the wires have an insulating layer, they can be tightly wound together in circles. The denser the coils, the stronger the magnetic field generated, which greatly improves the ability to convert electrical energy into magnetic energy. In 1831, Henry tried out a newer electromagnet. Although it was not large in size, it could hold up to 1 ton of iron. The invention of the electromagnet has also greatly improved the power of the generator.

Shang Wen is familiar with this period of history. Because, if there is a power outage in society for one minute now, human society will almost stagnate, if there is a power outage for one day. That is disaster. Humans can endure more than without water and food.

Shang Wen picked up his notebook and started recording. Then it was handed over to the craftsman, and then the first batch of talents in electrics was separated from the craftsman. Now the entire arsenal is about to become a giant laboratory. Inventions are everywhere. While the craftsman was busy with production, he began to pay attention to observation in order to invent something. This is a good phenomenon.

"General, please." A craftsman's voice came. Shang Wen immersed himself in writing something.

When Wang Jian saw that Shang Wen was immersed in what he was writing, he understood Shang Wen's character. This is the time when thinking is most active. It's also when most of the inspiration comes. At this time, even King Qin had to wait cautiously. He didn't even dare to make a sound.

"It's General Wang. Disrespectful, disrespectful." Shang Wen said with his head buried.

"Just sit down." Shang Wen still immersed himself in writing.

"By the way, is there anything about General Wang?" Shang Wen asked. Speaking and began to put down the pencil in his hand. Then tear it off and hand it to the craftsman who serves the dishes and delivers water.

"Mr. Qin is still so busy. The old man wanted to come for this technology. The old man checked the musket group. The impact was too big." Wang Jian said.

"Oh. If this is the case, the impact on the general is not enough. Come." Shang Wen said, leaving the house with Wang Jian's hand.

Shang Wen took Wang Jian to the various workshops of the arsenal.

Wang Jian was still eye-opening. The first thing I saw was the hydraulic press. A huge hydraulic press can press a red-hot iron block into a thin piece of iron. It was the first time that Wang Jian saw such a great force. Shangwen explained to Wang Jian that this was based on Pascal's law. Then make a simple gesture.

Then there is the machine tool, where a lot of barrels are produced. The speed of the barrel has been greatly accelerated. Then there is a four-wheeled carriage, which is comparable to a truck and has more than double the load capacity of an ox cart. And it's fast. Especially on highways, you can drive fast. There are also bicycles. If it was useless to make bicycles in the first place, then the usefulness of bicycles is beginning to emerge. Mainly the huge changes in combat weapons. It turned out that combat weapons require close combat, relying on soldiers' fighting skills, so now. It's already very different. As a brand-new way of maneuvering, bicycles have begun to have a new market. military.
