Chapter 211: The Huge Gap (Third Update, Asking for a Monthly Pass)
The frequency conversion just now only simulated the situation that occurred when the ship was turbulent in the ocean, and the generator was unstable, and as a result, the whole step meter of Yuhang Group directly failed to withstand it, burned and scrapped.
This is the Endeavor factory in order to test the whole step meter and other power equipment, in the wire circuit installed protection measures, otherwise just with the current impact just now, it is enough to burn two extremely valuable generators to scrap.
Manager Huang's face was ugly, because the whole step meter tested just now was produced by their factory, and the whole step meter of their factory had not experienced similar tests in the past, but this kind of imagination had never happened, but today it was unprecedented to come to such a time, which made Manager Huang only feel that the old face was hot.
Jin Jingwang's face is not much better, the explosion of "poof~~" is no different from the slap in his face, but he has to bring more than Manager Huang, after all, what kind of virtue is their own stepper, Jin Jingwang is still very clear.
"This whole stepper uses the self-synchronization method. ”
Just when Jin Jingwang and the others felt that they couldn't hold their faces, Zhen Jia pointed to the scrapped stepper just now and introduced: "With this method, it is necessary to increase the number of revolutions of the generator to be merged to close to the rated speed, and then close the main switch of the generator first without excitation, and then add excitation, and use the effect of the self-aligning moment to pull the generator into synchronization." ”
Zhen Jia paused for a moment, and then continued: "So the advantages of this structure are obviously easy to see, that is, it is simple to operate, quick to enter, and does not need to add complex parallel equipment. ”
After saying this, Zhen Jia shook his head regretfully: "It's a pity that the advantages are obvious, and the disadvantages are even more obvious, that is, after the generator is closed, there is a large current impact, torque impact and a deep drop in the grid voltage, especially when the power of the generator set is about the same as the power of the grid."
In the usual ship power station, because the capacity of the generator to be merged is almost the same as the capacity of the running generator, the whole step instrument of this type of structure is not suitable for ship use at all, and more specifically, this is a type of technology that has long been eliminated. ”
Before Zhen Jia finished speaking, Manager Huang lowered his head in shame, their factory is the one that produces the whole step meter, and I don't know what Zhen Jia said is right.
But why do they still want to cooperate with the South Korean side, and even do not hesitate to stop the old stepper with better technology, it is not the name of Sino-foreign joint ventures, you must know that in order to attract foreign investment in recent years, the state's preferential treatment for joint ventures is called a big one, not only in terms of taxes, land, resources, and investors to give considerable concessions to joint ventures, but also in public opinion for the joint ventures continue to build momentum.
Because of this, once a factory becomes a joint venture, the status and net worth are all the same, not only are they superior everywhere, but also take advantage of the state's preferential policies, which also allows these enterprises to have a lot of arbitrage space.
Therefore, in order to obtain this title, many factories do not care whether the foreign businessmen they cooperate with have the strength or not, as long as they can close it.
Manager Huang's factory obviously belongs to this situation, and they don't know what about the Korean stepper? Naturally, it is clear, but so what? The joint venture can bring them greater benefits, and what is the problem with the poor production of the stepper?
What's more, this kind of poor stepper sells better and earns more, so it naturally has to be greatly produced.
Thinking of this, Manager Huang seemed to realize something, turned his head to look at Jin Jingwang beside him, but found that Jin Jingwang at this moment did not have much anger, although his face was also unwilling to be debunked, but on the whole he was much calmer than him.
At this time, the whole step meter produced by Xiangxi factory has already been installed between the two generators by the staff, as the operator presses the start switch, the diesel engine runs, driving the generator to generate electricity, and then the operator closes, the current is parallel, and the whole step meter starts to work.
It didn't take long for the frequency conversion of various ship vibration simulations to change one by one, and the whole step meter of Xiangxi Plant was still running in an orderly manner, and there was no abnormality at all.
Seeing this scene, not to mention an insider, even a layman can understand that there is a huge gap between China and South Korea in the whole step.
In fact, it is true that although the Xiangxi plant is not a professional factory for the production of the whole step meter, it can be used as an instrument factory for submarines, and the whole step meter is no stranger to them.
So when they received Professor Qin's proposal to support the Endeavor Factory, Xue Qiang, the director of the Xiangxi Factory, didn't say a word, and directly nodded and agreed.
As long as there is production, the production line can be maintained, the worker team can be maintained, and the workers can be fed, so what is strict or not, Xue Qiang didn't pay attention to it at all.
At that time, they were able to build the factory in the deserted mountains, and the hardships and sweat they suffered during the period were too many to count.
Therefore, the technical quality control standards of Endeavor Factory, which is troublesome in other factories and cannot be avoided, are implemented without resistance in Xiangxi Factory, from the factory director to ordinary workers, all in accordance with the above requirements.
As for the product, it is a whole stepper designed by the Ship Machinery Research Institute in the mid-seventies for a new generation of domestic destroyers, which is not only exquisite in structure, but also has good versatility, and is more commendable in terms of durability.
It's a pity that China's new generation of destroyers has been on and off again since the end of the fifties, and the mid-seventies have not escaped this curse, which has also prompted this whole stepper to be shelved into a technical reserve.
This time, in order to support the Endeavor Factory, and also to increase research funds, the Ship Machinery Research Institute generously took out the design data buried in the pile of old papers.
With a united team, unique technology, and strict control standards, if the quality of the whole step meter in Xiangxi factory is not good, it will be called intolerable.
And this has also been unanimously recognized by the whole Endeavor factory, especially Zhen Jia, who simply loves this worry-free and labor-saving stepper.
Originally, Endeavor Factory was going to strictly test itself according to the standards provided by the Japanese side, and then notify the Japanese side to adjust the purchase intention of the supporting facilities.
Stretching out his face so unafraid of death, Zhen Jia naturally didn't mind slapping it over.
Of course, Jin Jingwang saw the huge gap between China and South Korea in the whole step, but it is no wonder that no matter how generous Europe is, it is impossible to sell you what is at the bottom of the pressure box, otherwise you will, they really want to drink the northwest wind?
Therefore, it is natural to give South Korea an obsolete technology, but even if it is so, it has not been given completely, and it needs to be explored by itself after South Korea goes back, so it is strange that the whole step meter can be good.
But his own is not good, he can't get better if he doesn't wait, no, what is in front of him is very good, so Jin Jingwang was not ashamed after being slapped in the face at all, but his eyes were full of brilliance, and he said to Jiao Dalin: "Mr. Jiao, can you transfer the technology of this stepper to us?"
