After solving the sealing problem, the subsequent improvement of the steam engine was easy, and the cooler was successfully made..
After the cooler was made, the force on the push rod was obviously much stronger. It saved wasted heat, and the effect was immediate.
Next, he made a two-way air intake cylinder. He opened the air intake holes on both sides of the cylinder. When hot steam was injected into the left side of the cylinder to do work, the other side of the cylinder would close the air intake hole and connect it to the cooler, thus creating a negative pressure suction cylinder. The gases on both sides of the pistols exerted force together, pushing and sucking the pistols in one direction to increase the output force.
With the oil-soaked linen as a starter, this time, he used the oil-soaked hemp rope to seal the connection between the push rod and the cylinder. The effect was quite good. The hemp rope was very tight after being soaked in oil, and it was quite elastic. Because of the grease, the friction was small. After tying six layers of hemp rope to the push rod, the steam could not be squeezed out.
Lin Feng was reminded by the craftsman to come up with the magical effect of soaking the hemp rope in oil. However, in the future generations before transmigration, in fact, until the 19th century, there were still many steam engines in the Ying country that were sealed with oil-soaked hemp ropes. The museum in the Ying country still preserved the objects in the future.
He made a barrier on the two air intakes. Every time the shutter was slid, the two air intakes would be opened and closed in turn, connecting to the boiler in turn. The shutter was controlled by an eccentric ring connected to the top of the sliding rod, and it automatically switched up and down with the sliding rod.
Every morning, Lin Feng would ride a horse to the Fan family's manor and return to Tianjin at night. He worked hard in the two places and spent more than 20 days solving a series of small problems. After that, he successfully made a Watt steam engine. The steam engine was quite powerful. It had the strength of at least five oxen.
Seeing the Watt steam engine, the blacksmiths who participated in the trial production of the steam engine surrounded the steam engine and looked at it in amazement.
Steel and flames combined to become something that could move, and it was so powerful. Although the craftsmen had participated in the trial production, they had only participated in a portion of the production. At this moment, there were still many things that they did not understand. They were shocked by the Governor's technology.
"Viceroy, this strength is even greater than a few cows!”
"The Viceroy is too amazing. This machine can be used in many places!”
"The Viceroy must be the reincarnation of Lu Ban!”
Lin Feng smiled and emphasized the confidentiality regulations to the craftsmen.
He was going to follow the example and make a few hundred larger steam engines. This way, he could install them on the ship and become the power source of the ship's paddle wheel.
A ship with a steam engine was a ship that could go out to sea regardless of the monsoons. Using a ship that could go out to sea all year round for ocean trade, Li Zhi seemed to have seen a lot of silver waving at him. After that, Lin Feng immediately prepared paddle wheels and installed steam engines on all the ships.
However, the steam engine could not only be used as a ship's motive force, but could also provide power for many industries.
During the battle with the Tartars in the capital region, he realized that his troops lacked armor. Without the protection of armor, soldiers were extremely vulnerable to the enemy's arrows. Even if they were shot by arrows, they could be seriously injured.
Although they had seized a large number of Qing cotton and chain armors, as the army expanded, these armors might not be enough. Moreover, most of the items seized were cotton armor. It was too hot to wear cotton armor in summer, and there was a risk of heatstroke. Lin Feng planned to make his own new armor, using high-quality crucible steel as raw materials, and using a steam engine to drive the forging hammer to forge the steel breastplate, helmet, and shoulder armor.
With steel breastplates, shoulder plates, and helmets, the Tartar archers 'bows and arrows were basically ineffective against the soldiers from a few dozen paces away. The ability of a bow to penetrate armor was extremely limited, especially in the face of armor forged from high-quality steel.
The forging hammer driven by the steam engine was also very simple. It was a big hammer supported by a long wooden handle lever, moving up and down. The steam engine kept pressing down on the wooden handle, and the lever lifted the big hammer and smashed it on the forging piece. Compared to a manual hammer, a hammer driven by a steam engine was much more powerful.
Such hammers could increase the efficiency of blacksmiths by dozens of times.
The few newly recruited blacksmiths were not used to making things out of the blue. When they saw the huge hammer weighing hundreds of pounds being lifted by the steam engine again and again and smashed heavily on the anvil, they were dumbfounded.
"Is this an immortal spell?"
"Viceroy, what kind of machine is this? Isn't it a little too powerful?”
He smiled and said," This is a steam engine. It's a secret of the Fan family. You can't tell anyone about this machine." The person who leaked the secret will lose his head."
In fact, the steam engine was not afraid of being leaked. Other than himself, other craftsmen would not be able to understand the principle of the steam engine even if they dismantled it, let alone replicate it. Moreover, the Ming Dynasty was in chaos now, and there was probably no one interested in stealing the steam engine technology.
