Large steam engine, for any steam engine factory, is a more rigorous, but about 5000 tons of steam engine, for the northwest, is not a difficult thing, especially with far more than the world's machine tools, as long as there are design drawings, as long as a skilled processing team, a few days of hard work, enough to produce them.

In fact, after receiving Yang Yuanzhao's order, the steam engine group almost allocated most of the manpower for the production of this, and it only took 3 days at most to complete the production, and through the fast railway and water transportation network in the northwest of Guò, the steam engine was transported to Shanghai.

It took only 9 days to produce and transport, and when two 6,600-horsepower reciprocating steam engines arrived in Shanghai, unloaded them as quickly as possible, and placed them in front of a group of shipyard engineers such as Pierre, they were not only surprised but surprised.

On the one hand, because of time, they know very well that in China, thousands of miles away in the interior, to transport this thing, how long it takes, maybe seven or eight days are on the road, in fact, through the northwest railway network, it only took a few hours, after the transformation of the Pinghan railway is also relatively fast, the only in Wuhan slightly delayed a day, but found the fastest steamboat, it took less than 3 days, to arrive in Shanghai.

On the other hand, what makes people wonder is the shape of this steam engine, which is slightly different from the common steam engine, and seems to be more reasonably designed, the overall volume has been reduced a lot, and a lot of unnecessary things have been removed, which looks extremely exquisite.

The steam engine is the first industrial achievement, starting from Watt's improvement of the steam engine, the practical steam engine, almost affected hundreds of years of industrial history, the steam engine is placed on the railway, that is, the train, which led to the improvement of bulk goods transportation, countries have built millions of kilometers of railways, and the railway has become one of the main bodies of the great powers to transport arms and economic aggression; The steam engine is placed on the textile industry, which is to replace the textile industry of water power**, and the British textile industry has almost occupied the entire world market after converting from water power to steam power; The steam engine was placed on the ship, the steamship made of steel began to appear, and the history of human conquest of the sea began to go deeper, all-steel warships, all-heavy artillery warships, and even the current 30,000-ton super dreadnoughts, human beings began to use steam to push steel monsters one by one, and the ocean could no longer stop human thinking.

In hundreds of years, the steam engine has developed rapidly, in such a short period of time, the steam engine is far from developing to the extreme, the original materials, especially the emergence of rubber, make the steam engine better sealed, but there is no complete isolation, large steam engine, steam leakage and power loss are also common things.

The steam engine in the northwest is based on the original British steam engine, especially the military steam engine based on the Haiqi, improved and developed, Yang Yuanzhao through the guò all-in-one machine and some materials in the 21st century, constructed a part of the polymer compound, which can greatly reduce the weight of the steam engine, and reduce its structure, but on the kinetic energy, there will be no greater loss, especially some from the design of the cylinder block and the change of high temperature and humidity resistance of the material, the steam engine can be in the cylinder, The more heat is stored, and the kinetic energy is also sufficient, and the most important thing is that polymer materials and new materials can reduce the deflating of the steam engine to a minimum.

Among these steam engines, the only use of the design of later generations, is the heat recovery device, originally, after the steam engine pushed, the waste heat energy, with water vapor and cooling system sent out, is equivalent to a waste, but also consumed a link, slightly improved, with a special heat effect recovery device, to complete the secondary use of heat utility, the original ineffective, may reduce the efficiency of the steam engine waste heat energy, recovery and concentration, continue to use, these major fuel savings.

This 6600 horsepower double steam engine marshalling is not the best product in Baotou, some of the more powerful extreme limit zuò, but also secretly sealed by Yang Yuanzhao, only in the power room of Yinshan, even if it is this, it is just an ordinary model, not even the largest, the largest can already reach a single 13000 horsepower, which is much better than foreign products.

Because of the previous machine tool thing, Pierre did not underestimate this steam engine, according to Nie Yuntai's order, he organized 12 engineers, the steam engine was the first to test, in the start time, start vibration, and stability dìng, are greatly outstanding, especially the sealing performance, almost no steam leakage, the whole operation process, rarely exhaust to the outside, let alone add water at any time, especially after the operation continues, after one or two hours, the temperature of the epidermis has been at a low level, This will make the power room more gentle, and there will be no leakage of a large amount of water vapor, so people can't stand in.

The horsepower test was carried out by driving the transmission device through guò power, and according to the calculations of the engineers, only 5000 horsepower could drive the steam engine, and it was obvious that the steam engine was easily completed. The power plant runs quite quickly, according to the estimates of engineers, at least above 6500 horsepower, which is basically 30 more than the design.

Even after the initial contact, Pierre was already convinced that the quality of the steam engine produced in the northwest was relatively not bad, and that stability was an important aspect related to the performance of the ship.

The new, larger power unit gave Pierre more ideas, although at this moment, it is impossible to change the structure of the ship, more powerful power and smaller steam engine, will make the layout of the power unit more marginal, just 3000 horsepower increase, it is enough to increase the economic speed of the ship by 0.5 knots, do not underestimate this, 0.5 knots is still a relatively large value for ocean-going ships that are at sea for several months.

Many parts of the power plant need to be adjusted, and even the structure of the hull has been fine-tuned, making him more suitable for higher ship speeds and saving some of the power, and after a day of endurance test introduction, a bigger surprise was reported to Pierre, the power unit produced by Baotou, under the same power, compared with the strongest steam engine they came into contact with, saving about 30 energy.

This is a huge number, the seller of the freighter, are for shipping, one of the biggest interests of the shipping industry is consumption, in addition to the necessary number of people to control a single ship, energy saving is a key point, the same carrying capacity, the same voyage, even if it can save 0.1 coal, it is enough to make people tempted, this represents the real interests. But all of a sudden, 30, in this case, can completely reduce the price of about 5 goods, under the premise of ensuring time, the business is not the same as flying, the ship is a consumable, must be run to be able to generate profits, run fast, use less people, consume less, this is the limit of the cargo ship's pursuit, obviously this steam engine has done.

Pierre couldn't believe it, and asked the engineers to continue monitoring, to give 3 days of results, 3 days later, the final value, reported to him, the average energy saving of three days is about 32, has confirmed that this steam engine is not only outstanding, smaller size, energy saving performance is also amazing.

Based on the design of later generations, it can avoid most of the problems of the steam engine in this era, good power conversion and sealing, so that the heat energy is converted into kinetic energy, more reasonable, more not easy to waste, the most important thing is that in some links, Yang Yuanzhao also pioneered the design of heat energy recovery, with the help of special devices, the residual heat energy generated by the steam engine is recovered, just this one, can make the energy saving of the steam engine, has a huge improvement.

I thought it was stuffed by the major shareholder, a waste thing used to make money, but I didn't expect that it was a huge surprise, although the durability is still being tested, but this energy-saving benefit is enough to promote Pierre's choice, durability has been carried out for 3 days, as long as it is guaranteed for more than 10 days, this steam engine is acceptable.

Marine steam engine, the maximum continuous operation time is 21 days, but that is the loss of the overall life, ocean-going cargo ships, generally between 8-12 days, must enter the port, on the one hand, overhaul the steam engine, on the other hand, must also add coal and water operations, 10 days is acceptable, even as long as the steam engine maintains performance, 7 days can also be accepted.

The excellent performance of the steam engine, so that Pierre could not continue to test the steam engine, leaving the least personnel to stare at, he has contacted many engineers, began to make slight adjustments to the 4500-ton cargo ship, when the time comes, the ship's load weight will increase by about 300 tons, which is space saving and material saving, the maximum speed can be increased by 2.5 knots, and the economic speed can be increased by 1 knot, so that under the premise of about 1.5 knots higher than most ships, it will save about 22 energy than ships of the same mileage.

An initiative, about to be born under Pierre's efforts, and even this ship, can compete for the design of the best fast ship, this achievement, so that Pierre excited, he never thought that he could get involved in these awards, now, under the impetus of China's steam engine, he even has a huge grasp, this kind of honor push, so that Pierre, a loose Frenchman, have become busy, began to organize personnel to work overtime, must be in the shortest possible time, to complete the overall adjustment, He also sent someone to inform Nie Yuntai that he could conduct another round of negotiations with Swire on the total cost of the vessel on the performance improvement and the reduction of the delivery date, and it was certain that the other party must give a more reasonable price and reward for the performance improvement and efficiency improvement of the ship.
