"Ignition." With Yang Heng's order, several workers began their work, and this was already three months after the boiler officially reached the practical level.

Although Yang Heng also did some other things in the middle, the production of the parts of the steam engine here did not have any effect, because these things have already begun to be done by professionals, and Yang Heng will not be better than them in any case, especially those lathe workers, they have really worked hard to learn, and they have now been able to give full play to the energy emitted by the waterwheel.

But that's it, the power of these waterwheels is still very poor, the work is very slow, but this also makes these lathe workers more their own processing parts more attentive, if the processing of a waste part, then it will be delayed for a few days, or even more than ten days, is a small part, not a short time to be able to process.

Therefore, in this day, a small half of the time is wasted on measuring the size of the parts, but it is such a precise measurement that the defective products, or even the waste products, are not produced directly, so the first test steam engine is considered to be out of the factory.

"You are all optimistic, this mark, yes, these are these two marks, they must be aligned when the machine is stopped, if they are not aligned, they may not work properly."

The steam engine developed by Yang Heng is the simplest top-ball steam engine, but he doesn't remember what the name was in his previous life, and he also made improvements, that is, he converted the energy into a crankshaft that drove the flywheel to rotate.

"Boom ......" "Boss, the air pressure has arrived." Several workers at work shouted, "Open the valve." "Boom ......" with a dull sound. Then I saw a puff of steam coming out of the side. And then there is. Gaden, Gaden's voice came out, but it wasn't the sound of a train, it was the sound of a crankshaft driving a flywheel to turn, and then I listened to the sound faster and faster.

"Close the valve and try to adjust the speed." At this time, you can only use yelling. Even with gestures.

At this time, several workers next to the boiler were sweating profusely, one was summer, and the other was that the steam was really hot, and it seemed that the reuse of the steam, and even the remote discharge of the steam was also a problem, or it was to add a fan to the side of the flywheel to cool down the workers.

After more than an hour of testing. This steam engine is officially a success, but it is durable or not. It's still a problem, however, Yang Heng feels that this power is still very sufficient, this modification can be used to drive the lathe, and by the way, it is also tested for durability, but if you use this kind of steam engine to get on the car, Yang Heng still feels that it is not enough, this power should not be enough, and the most suitable should be a reciprocating steam engine, or even a steam engine that uses steam many times.

And this first one, which can only be used to test the durability of the parts, and the durability of the lubricating oil, you must know that this is the first time to use the lubricating oil on high-temperature, high-speed machinery.

Speaking of this lubricating oil, this is also a by-product, it is a by-product developed by the Taoist chief in the mountains when he was developing eucommia gum, originally they thought it was useless, but they made not much things and put them there, pour it, and be reluctant, but don't pour it, inadvertently, Yang Heng found this thing.

"Dao Chief, what are you making here, black?" "Back to the owner, this is a kind of thing we developed some time ago, but it feels slippery, but it has no practical use, and I am thinking about whether it has fallen." "So, this thing doesn't burn your hands." Yang Heng is very careful, anything, if he doesn't know the Dao, he will generally not do it, you must know the Dao, here are some immature chemical experiments, maybe there is something burning in it.

"I don't burn my hands, I just pinch it with my fingers and it feels slippery." Hearing this, Yang Heng was also relieved, he dipped a little bit of this black liquid with his fingers, "This, this is lubricating oil, do you have any records?" Yang Heng was surprised, these Taoist chiefs tried some things, and actually made this lubricating oil, which should be used on the axle of the carriage and even the waterwheel, how good the effect should be, and the lubricating oil he used before was all vegetable oil, this vegetable oil is not a particularly good lubricating oil, but only slightly stronger than nothing, some parts are still very badly damaged, Yang Heng has been thinking about how to make this lubricating oil, but in his mind he can't think of any ideas, this is not a professional, I really don't know how to make the principle, but I know that this is a kind of thing refined from oil, and there are even other chemical effects, but I didn't expect it to be inadvertently created in the hands of these Taoist leaders.

"Boss, this is a bit of a problem, although we have a record, but we have forgotten what day it was made." "Don't worry, you recall, and then do the test again in those days, don't you find out the formula, and in the future, whether you make useful or useless things, you will label them so that we can find them." This is the history of the discovery of this lubricating oil, however, now that the Taoist leaders have something to do, Yang Heng will not believe that this lubricating oil will be durable in high-temperature machines, so it must be re-studied, but with this foundation, it is very simple to study again, and Yang Heng believes that this black thing will definitely become a clear thing, or slightly with some other colors, not black colors.

Although the experimental mechanism of the first unit has been made, some problems have not been solved, the first one is to solve the problem of machine cooling, you must know that the temperature is high, there will also be various problems, however, this Yang Heng no longer needs to be responsible for himself, he has handed over to his subordinates to do, and even some theoretical things, he also handed over to professional people to solve, that is, some arithmetic is good, they not only have to calculate some equations, Even have to write out some theoretical things, naturally, these things need to be discussed by Yang Heng, and even have to disassemble and assemble the machine several times, so that they can really understand this principle.

There is also a steam engine power to the lathe, so, on the other side of the steam engine, a flywheel is added again, and a pulley is added to the flywheel, this pulley is used to drive the lathe, and an elastic pulley is installed on the lathe, that is to say, after the pulley is tightened, it will drive the lathe to rotate, if the pulley is relaxed, the belt will be loosened, and then the lathe can directly brake the car.

To say that the test model is troublesome, the first thing to do is the explosion-proof problem, in this way, there is a thick stone wall between the lathe and the steam engine, that is, the workers in charge of the steam engine, but also remote operation, the same coal delivery, remote control valves, have been lengthened, and even modified, this is also for the sake of safety, however, once the test is successful, it will not be so troublesome, lathe, steam engine, that is, next to each other, the operation will be directly changed to two people to operate, one is to operate the steam engine, One is to operate the lathe, so that it is much easier to control the speed or some other aspects.

However, what Yang Heng wants to do most is to use a steam engine to generate electricity, once the steam engine is used to generate electricity, in this way, the lathe can be driven by a motor with a relatively small sound, and then, that is, there will not be a generator for each family, so to speak, a Chang'an City can use a power plant to supply electricity, and even the heating may be supplied together.

"Owner, this lathe driven by the new machine is very strong, and the parts that used to take a day to make are now not required to be made in half a day, but yes, this noise is too loud."

Yes, the noise is too loud, when they talk to Yang Heng, they all use yelling, and even after getting off work, they are talking loudly to others, and their ears are affected.

"This, you can rest assured, once this steam engine is successfully tested, it will immediately be powered by a noiseless electric motor." Yang Heng didn't care if the worker understood or didn't understand, he still said to him loudly. (To be continued......)
