The composition of the steam engine is very simple, mainly composed of cylinder, base, piston, crank connecting rod mechanism, slide valve valve valve mechanism, etc., and the steam must pass through the slide valve valve valve mechanism to select the air inlet before entering the cylinder.

There are three channels in the mechanism, one exhaust port, two air intakes, each time an air inlet and an exhaust port work at the same time, controlled by a spool valve.

When the steam enters the mechanism, it must enter the cylinder from one air inlet port, thereby pushing the piston to move, and the gas on the other side is discharged through the exhaust port, entering the condensing device, and then entering the boiler for reuse.

The piston is connected to a connecting rod, which conducts power and drives the wheels to turn.

The connecting rod is also connected to the spool valve valve mechanism, when the piston moves to a certain position, the connecting rod drives the valve mechanism to change the position of the steam inlet, pushes the piston in the opposite direction, the original air inlet is connected with the exhaust port through the spool valve control, becomes a new exhaust channel, and the gas is discharged, so reciprocating, this is the power device,

To this end, the institute needs to solve the problems of manufacturing high-temperature resistant seals, manufacturing pipes of various shapes, threading, lubrication, riveting, etc.

These components are drawn in advance by the researchers, and some are temporarily processed according to the dimensions, and some are made by hand. Due to the high accuracy requirements, the scrap rate naturally remains high, which is also the main flow of research funds.

Rubber raw materials brought back a lot, for the time being, there is no need to worry about the lack of materials, now what is lacking is the method of plastic refining, this problem Wang Xuan is not clear, the need for the Institute to continue to test. It really doesn't work, and it can only replace the finished product with a semi-finished product.

It is best to use seamless steel pipes for pipes, drill holes after steel forming, then forge, and finally anneal, and shorter ones can be directly cold drilled.

These processing equipment and heavy industry parks are available, some need to be re-customized, and the manufacturing is not difficult, the key is whether the material process is passed.

Wang Xuan plans to put the processing workshop in 404 if the heavy industry park can't provide enough equipment driving power, after all, there are large reservoirs and waterwheels there, and the power is sufficient. It depends on the final design drawings to see how large the steam engine is.

Pipe bending can be done by filling to reduce deflating, which can be easily done with an auxiliary press brake.

There are many suitable filling materials, and the common sand is one. Fill the pipe with sand, seal the pipe at both ends, heat the place to be bent, and then pass the press brake to bend it easily.

There are two kinds of threads: inner screw and outer screw, both of which are turned out of the lathe.

The outer screw is that the turning tool moves forward at a constant speed, and the raw material rotates at a constant speed, so that the turning tool will leave a uniform 'scratch' on the surface of the raw material, which requires a high speed on both sides, and needs to be carefully calculated to measure their respective speeds.

The inner screw is drilled first, and then the turning tool goes in, and the thread is turned out.

Wang Xuan estimated that the scrap rate of this project would definitely drive the researchers crazy.

However, everything is difficult at the beginning, once the practical steam mother engine is built, it will greatly improve the processing efficiency and yield of the workpiece, which is the most intuitive embodiment of the industrial revolution.

At that time, both the control of speed and the control of time will be raised to a new level, and the accuracy will be far greater than you can imagine. Workpieces and semi-finished products that seem to be cumbersome to process will be easily completed in front of the equipment driven by the steam engine, and the efficiency of one equipment will be completely destroyed before the entire factory, which is an epoch-making progress.

The researchers of the steam unit know exactly what kind of work they are doing, and they are hungry for success and glory.

The steam engine has been established since the auspicious kingdom was still auspicious, and now in the past six years, there are still achievements.

Hundreds of wooden working models were made, and there were even two small all-glass models, and they came up with a mature theory after continuous experimentation, improvement, trial and improvement.

Nowadays, the auspicious development is good, the processing equipment is constantly updated, the material technology is constantly improving, and the types are also increasing, it is time to make achievements.

As for lubrication, Wang Xuan knew that it was a product of petrification, but so far nothing has been found. Even with oil, he couldn't refine it, so he planned to use olive oil instead of lubricating oil.

The way of oil supply is not difficult, and there is an oil guide groove and an oil supply tank at the friction place, and the oil can be transported by a special oil supply pipeline.

For steam engines, cold riveting can only be used, unlike the hull, which requires hot riveting.

Although the steam engine will vibrate during operation, due to the sealing requirements, the cold riveting will fix and lock the upper and lower connectors, and will not loosen due to vibration, resulting in air leakage.

On the contrary, the hull has a high possibility of being impacted by water pressure, shells, etc., and the hot riveting has a certain elastic space to reduce this type of direct impact force. In addition, it is also convenient for maintenance and replacement of iron sheets.

As for the power output mode, it will use two types: chain and belt, and the high-power output will be geared.

In order to produce these accessories better, faster and more accurately, Wang Xuan must understand all kinds of equipment of Jixiang, evaluate the production capacity, and update it as soon as possible if it does not meet the standard.

On the tenth day of the first lunar month, Wang Xuan came to the design team, which often traveled back and forth between various enterprises and research institutes, collecting requirements, and then analyzing the design.

Wang Xuan's arrival made everyone very excited, and Wang Xuan also praised the proud achievements of the design team in recent years, and the atmosphere was so warm that the applause continued.

"The achievements are in the past, the difficulties are realistic, the challenges are in the future, and this time I bring you a new research topic, the design and production of finishing equipment. ”

As everyone knows, this is a set of production equipment specially set up for supporting steam engines, which requires high precision, high output, and high quality, which is not easy.

"Although it is the equipment for the steam engine project, it can be used for other projects, as long as the operation path is adjusted, so strictly speaking, it is not a special supporting equipment. This is a new topic, related to the development of auspicious can leap to a new level of the problem, once the equipment is successfully developed, auspicious will not be afraid of any threat, even if it is the enemy of the world. ”

This is a bit of a big statement, but it is also well-founded.

Once the steam engine is successfully developed, any accessories can be mass-produced, which can not only reduce manpower demand, release productivity, but also improve yield and precision.

The reason why China, which had a population of 400 million, was pushed to the point of almost exhaustion by the island countries in the land of projectiles was that it had completed industrialization and bullied backward agricultural countries with the production advantages of industrial countries.

This is the generation difference, the difference between adults beating children, and foreign guns and big knives.

Everyone sitting here knows very well why Jixiang resisted the red flame of millions of people with a population of more than 100,000 people, and finally ate it, it is because of the combination of advanced tactical thinking and asymmetrical weapon attacks, with mental calculation and unintentionality, step by step, to win the final victory.

If there is no artillery in the naval battle with the Combined Fleet, even if Jixiang is finally defended, what is the cost?

There are also new warships, which are invulnerable to fire and water, and have huge firepower. With the paddle wheel, it is full of power, and it can both win and run.

Otherwise, there is no such thing as the Southern Continent.

These are the benefits of new technologies, and as a researcher we know better.

Technology is like sailing against the current, if you don't advance, you will retreat, because others will not let go of such an obvious opportunity to catch up. Auspicious is like a firefly in the night, inspiring all parties to learn auspiciousness and catch up with auspiciousness, which is the disadvantage of the first place, and of course it is also an advantage.

"You only need to design according to your needs, you don't have to think about the material, this is the task of the material group, we can't just cross borders. ”

As soon as Wang Xuan's words fell, a burst of laughter sounded below.

Since research topics do not exist in isolation, and there are many upstream and downstream related projects, it is often necessary for various research groups to meet frequently to exchange results and experiences to inspire thinking and promote the achievement of projects.

"You don't have to take into account the production problem, this is the task of the project, in short, to complete the drawing design as soon as possible, both reasonable and practical, now we lack everything, waste ah." ”

This is a fact, although now there are Daxia leaders for auspiciousness to make a match, but that is also money to buy.

"In the past, we were very content to produce 1,000 catties of steel every day, but now our production capacity has increased more than 100 times, and the supply is still insufficient. At this time, we should not stop to alleviate the pressure brought about by material supply, but should try our best to solve the problem of material supply and meet the needs of development. ”

What Wang Xuan said to the design team is not untargeted, and if you want to develop sustainably if the conditions are insufficient, you must either open source or reduce expenditure, there is no other way.

Open source already has, that is, the supporting facilities of each collar, but in the supply of some materials, it is not endlessly auspicious, such as iron ore, such as salt, no one is a fool.

Throttling should start from the source, not just a problem of manufacturing, but a problem of the whole process.

Design is the source, and every material they save can be used in other places where it is needed.

In addition, it unlocks their design potential, improves the way their equipment operates, and increases efficiency, killing three birds with one stone.

"I know that you are very miserable, not only are your movements restricted, but your family cannot move freely like ordinary people, but these are all necessary measures, and I can't change them for the time being, so I can only try my best to compensate you.

In fact, it is the same everywhere, as long as you show enough value, you will not enjoy the freedom of ordinary people, because you have obtained values that ordinary people cannot get in almost their lifetime.

Heaven is fair, isn't it?"

The crowd was silent, but that's the truth.

They love to study and love this job, but sometimes they are tired and bored, and then they need the affection of their families to lubricate and prevent the accumulated dissatisfaction from exploding and blowing up their bodies.

Jixiang has done a good job in this regard, there is a special villa complex on Hunan West Road, and the idlers are not allowed to enter the west, and the whole area is the activity area of researchers and their families.

In addition to the absence of schools, there are no places left behind, leisure and entertainment facilities are complete, and various services are dazzling.

I did so much to relieve the pressure of the researchers, soothe their nerves, and maintain their energy and physical strength.

"I plan to gradually relax the restrictions on the activities of the researchers' families, but there will be restrictions on the number and time you can go home, and some secrets will be inadvertently spoken, especially by children, who will not be able to distinguish the value after hearing it, and will also leak it out inadvertently.

Now auspiciousness seems to be peaceful, quiet and peaceful, but how many dirty deeds are hidden behind this peace? I can say without exaggeration that the spies sent from everywhere can now form an army, at least a reinforced company. ”

Everyone laughed again, although the plan provided by His Majesty did not change the problem in essence, but at least it worked in a good direction, the country did not forget them, His Majesty did not forget them, and that was enough.

"You are all auspicious's most precious treasure, even if there is only a glimmer of possibility to make your life better, we will do our best to achieve it. ”
