Looking at the buzzing tram, the doctors thought about it. Pen "Fun" Pavilion www.biquge.info

Finally, Wang Erniu came back to his senses, "God, how many batteries will you need in the future!" ”

"Well said!"

Sun Yi immediately praised loudly.

The amount of electricity consumed is terrifying enough just to make electrolytic pure iron and steel by electric arc, not to mention the electric tiger-like trams!

Sun Yi disconnected the power of the tram and said, "Everyone look carefully!" ”

Sun Yi arranged for a sturdy craftsman to turn the wooden shaft by hand, and he was in the position of the original battery, holding two wires and touching them lightly.

"Smack"

A small spark is made between the wires.

Sun Yi asked everyone: "What does this mean?" ”

"Description...... Illustrate...... Trains can be powered like batteries. An electrician stumbled in disbelief.

Sun Yi was noncommittal, and connected a crank at one end of the wooden shaft so that the craftsman could shake the wooden shaft more forcefully, and at the same time, Sun Yi connected four copper brushes to the two poles of the copper foil large capacitor.

The train rotates to produce direct current pulses, which rush into the reservoir of capacitors like ocean waves, and open the gate at the other end of the reservoir to release water, resulting in a continuous and stable direct current.

Sun connected the capacitor to an electric gong made by an electrician, and when he pressed the electric door, the electric gong sounded "bang". Press the electric door continuously, and the electric gong "clang" non-stop.

Now no one doubts that the train can generate electricity.

Sun Yi inspired: "In addition to using manpower to drive trams to generate electricity, you can also use animal power, water power or wind power, and batteries can be used in these places. ”

"Capacitors are a kind of component that can store electricity, but after all, the amount of electricity that can be stored is limited, so the electricity emitted by the tram can only be used on site. If you want to store the electricity generated by the train, you need to have a more powerful component than the capacitor, which is the battery. If a capacitor is a big jar, a battery is a pond. Come on, bring the battery up. ”

Several electricians carried a few crockpots.

The crockpot was filled with water and two pieces of lead were inserted.

The electricians knew that Lord Lidel called this thing a battery, but no one knew how to use it.

Sun Yi connected the output of the copper foil capacitor to two lead sheets, and theoretically the tram began to charge the battery.

The standard voltage of lead-acid batteries is 2 volts, which can be as low as 1 when discharged. 5 volts, which can be up to 2 when charging. 4 volts. Lead-acid batteries are characterized by the ability to provide strong current in a short period of time, and the lead-acid batteries used for automobile ignition in later generations are composed of 6 lead-acid batteries connected in series, which can provide a large current of several hundred amperes at the moment of ignition.

If the crockpots in front of you are fully charged, they can completely replace the iron tank battery array that supplies power to the spot welding devices of Niu and Xue.

Several skilled craftsmen took turns rocking the tram, and the seemingly fluttering wooden shafts were unusually heavy when connected to the lead-acid batteries. Taking advantage of this time, Sun Yi briefly introduced the structure of lead-acid batteries, and at the same time gave a plan for mass production of blotting water.

At present, Sun Yi uses a simple mud furnace to produce sulfur dioxide gas produced by burning sulfur as raw material, and the gas produced by burning nitrate as a catalyst, and the gas after the reaction is dissolved in water to obtain mixed blast water. The problem is that ironwood also has not many reserves of sulfur.

Sun Yi drew four large water tanks on the blackboard, two by two, which were connected by a pottery pipe at the top.

Fill the first tank with plaster and heat it over a fire. When the temperature rises, the water in the gypsum is first forced out to form water vapor, and then the temperature rises to seven or eight hundred degrees, and the gypsum with calcium sulfate as the chemical component begins to decompose, releasing sulfur dioxide gas, leaving a calcium oxide residue, which is commonly known as lime.

Water vapour and sulphur dioxide gas rise into the second tank, where they encounter catalyst gases produced by burning nitrate.

The gas mixture enters the third tank through a terracotta tube, where they react with each other to form sulfuric acid. The sulfuric acid settles to the fourth tank, the temperature drops closely, and the sulfuric acid condensation is collected.

The water produced in this way uses sulfuric acid as the main component, and the concentration is greatly increased, which can increase the storage capacity of lead-acid batteries.

The raw material is gypsum stone, which has no cost and only freight, and the by-product of production is a mixture of lime and partially dehydrated calcium sulfate, that is, wear-resistant floor plaster, which can be used directly as a building material, or as part of the raw material for the outermost stone surface of ironwood to produce composite fiber armor.

When Sun Yi finished explaining, it was already time for dinner. The first lead-acid battery has been partially charged and can be demonstrated.

Use a lead-acid battery to connect the electric gong, press the electric door, and the electric gong "bangs".

Sun Yi clapped his hands and dusted off the chalk ashes.

The soldiers at the front are fighting bravely, and the technical roadmap at the rear has been planned. The next step is to rely on these craftsmen wearing doctor's badges to continuously improve power, efficiency, and reliability to come up with a usable product.

As soon as Sun returned home, the meal had not yet been cooked.

The first thing the milk baby said when she saw Sun Yi was: "Master, where is our bellows?" ”

Sun Yi suddenly sweated, "Our bellows...... Our bellows...... It has become a water tank that cannot be used. ”
