Wang Buxu continued to study this lathe.

Although it is crude, there is no doubt that this is definitely a good thing.

There are so many places where this thing can be used.

Almost all industrial construction uses this thing.

Especially the manufacturing of vehicles.

And with a lathe, the quality of the gears produced will be better, the axles will be more standard, and even the bearings are not beyond imagination.

"Your Majesty, although the service life of steam engines has made breakthrough progress, there are still problems. Judging from the current situation, steam engines of this quality still cannot meet the conditions for mass production!" Cheng Ju looked at it.

Wang Buxu actually looked at this grinder, and he couldn't help but feel a little bitter in his heart.

"Oh? What's the problem?" Wang Buxian continued to stare at the lathe and asked.

"Although this equipment can extend the service life of the steam engine, it is difficult to operate. We found the most stable master to operate it and made it 82 times before we were satisfied with it," Cheng Ju said.

"What? It's so difficult?"

"How can this be good!"

Everyone present is engaged in scientific research, so they naturally know the meaning behind Cheng Ju’s words?

Although everyone is not familiar with every aspect of the scientific research process, even the most stable masters are actually novices.

But his starting point is higher than that of ordinary novices.

Even if he becomes proficient in the future, if our expectations are higher and our mood is more optimistic, we can even increase his efficiency by half.

It would take a total of forty to produce a qualified finished product.

But after mass production, it is difficult to find so many excellent masters.

Therefore, for mass production, the yield rate may reach 70 to 80, or even one qualified product among hundreds.

"Dean Cheng, how long will it take to build one?" someone suddenly asked.

The others nodded repeatedly and looked at Cheng Ju.

This is a very critical issue. If you can make twenty or thirty pieces a day, then you will have to accept one finished product out of seventy or eighty. You can only make it like this first, and then slowly improve the process.

"In the beginning, we made one a day, and sometimes we couldn't finish it. Now it takes about three to four hours to make one," Cheng Ju said, which is why he thinks mass production is impossible.

After Cheng Ju said these words, everyone had only one feeling.

Finished...

Even a master requires three to four envoys. In conversion, although it is less than one per day, it is no different from one per day.

In the summer, the sunshine hours are longer, so the sun rises at Maozhi quarter (6:00). Even if you are prepared, you will have to start work at Maozhen quarter (6:30).

Sunset basically takes place at Xu hour (7 pm), so even if you don’t eat, drink or poop, there will only be six and a half hours of sunshine that day.

If converted, it basically equals three in two days.

If there are eighty, it will take nearly a month to produce a finished product?

This is a bit of a joke...

"There are many factors causing this, and people are just one of them. Another important factor is that the power provided by the steam engine is not stable, sometimes fast and sometimes slow. If you want to improve the yield, you need people to follow the power conversion of the steam engine.

Operation, but this requirement is too difficult. Even if one or two people can figure out his strength, they do not have the conditions for mass production. It is impossible for everyone to figure out this strength." Cheng Ju said again.

Everyone poured a basin of cold water on him.

Everyone's mood hit rock bottom again.

I couldn't do it before, so I was anxious.

Now it's better, it can be done, and the technical problems have almost been solved, but production has become a big problem again.

If you have the technology, but you can't build it, isn't this just talking on paper?

Wang Buxu was also thinking seriously about this issue.

Regarding the problem of steam engine power, he didn't have any good solutions.

He also understands the principles of today's steam engines.

It's a simple push, there's no difficulty at all.

Basically, it boils water and increases the pressure in the furnace. When the pressure in the furnace reaches a certain level, the steam starts to flow, pushing the piston to move, and the piston links the outside. This is the power output.

The inside of a steam engine is actually a boiler, and depending on the current conditions, or at any time, as long as it is a boiler, he will face a problem.

That is the control of the pressure in the furnace, which can be controlled by various instruments in later generations.

In the early days, workers used instruments to observe the pressure in the furnace. When the upper pressure limit was reached, manual decompression was required.

In the early years, boiler explosion accidents occurred partly because of poor quality or aging of the boiler.

But a larger part of the reason is due to the workers' mistakes. To be precise, they forgot to observe the pressure in the furnace.

The consequence of no artificial decompression is that the pressure in the furnace continues to increase until the cylinder cannot withstand the pressure, and then explodes.

Later, it became a CNC boiler, all operated electronically.

But even so, the manual pressure reduction device is still retained, and workers still have to check the furnace pressure gauge regularly. Once it is found that the pressure reaches the range without automatic pressure reduction, the boiler needs to be shut down for inspection.

If it cannot be shut down immediately, it will be necessary to manually reduce the pressure to ensure that the pressure in the furnace is controlled within a safe range, and then conduct inspections when it can be shut down.

There is no such condition now, so Cheng Ju used the simplest method to solve it.

Although it seems to be extremely crude, it is fully automatic.

That's right, it's a fully automatic pressure reducing device.

The principle is very simple, that is, add a baffle to the spout of the kettle, and add a certain weight to the baffle.

When the pressure in the furnace is not enough, the spout cannot be opened.

When the pressure in the furnace is reached, you can push the spout, and the excess pressure will be released instantly. The fastest update PC version::/

Manually only needs to check whether the baffle is blocked.

But this also leads to a consequence, that is, different pressures in the furnace provide different power.

It may not be visible to the naked eye, but there is actually a difference.

Especially when the pressure in the furnace is reduced, it has a great impact on the power. You will obviously feel a pause, and then return to normal.

The problems Cheng Ju encountered often happened at this moment.

There is no way to solve this problem even if you are not hungry. It has little impact on the tractor, as long as it can run.

But for this kind of unit that requires precision processing, the impact can be huge.

Even just because of this pause, a piece of material was scrapped.

Wang Buxu thought for a while, and when he encountered problems, he always had to solve them. Let’s solve whichever one is easier first!
