Chapter 669: Tim Ding

After all, it is the first time to design such a large generator set, if the margin is not enlarged a little, in case the design requirements are not met during operation, then the project is considered a failure, which is very unfavorable for subsequent development. After all, this kind of large-scale equipment has very high requirements for the strength of various parts, so what is safer than designing it directly according to higher indicators?

Therefore, this set of equipment is said to be 300,000 kilowatts, but if there is no problem with the test of each part, then there is no problem at all according to the operation of 360,000 kilowatts.

And it should also be noted that under normal circumstances, it is difficult for the generator set to achieve the designed operating conditions, one is for safety considerations, and the other is that the electrical load cannot just reach the design ceiling, so the general generator set is operated under seventy or eighty percent of the load, so that if the load needs to be increased, the load can be changed in time, so as to achieve timely adjustment of power supply.

Therefore, the power plant has an installed capacity of 600,000 kilowatts, but the actual power supply can only reach a little more than 500,000 kilowatts, and it is impossible to directly reach 600,000 kilowatts.

This is also the reason why the No. 998 plant only dares to produce alloy steel on a scale of 5.5 million tons, after all, this load has already used up more than 300,000 kilowatts of load, accounting for a very large proportion of the power plant, if it is increased again, the power supply of the power plant will basically not be able to guarantee a stable supply. And the generator set that Li Zhao is making now can directly operate according to 300,000 kilowatts, after all, the margin is a bit much.

In this way, the boiler continued to run in a cycle, this time ready to run for half a day, and then carefully inspect the boiler to see what problems will occur, which is very important, especially for the flaw detection inspection of each part, it is the top priority, only to withstand the test can ensure the safety of production.

Soon at four o'clock in the afternoon, the boiler gradually stopped, and then everyone began to cheer, knowing that today is an overload operation, if there is no problem when testing, then that is, the design can be put into use, and most importantly, lay a solid foundation for the supercritical unit.

For supercritical and even ultra-supercritical units, the most important thing is how to boil water, how to ensure that sufficient pressure, temperature and flow of steam are produced. The remaining problem is very simple, that is, to ensure that the strength of the boiler meets the standard, and for this, it is simple.

There are excellent metals in the factory, there is no problem at all in this regard, and there are large-scale forging equipment, and there will be no problem with the processing technology, under such conditions, a supercritical test was carried out, then the next supercritical generator set will not be a problem, and this time due to the relaxation of design parameters, the actual operation should also be able to carry out supercritical operation, and at that time, the power will become higher.

For the current power plant, this is definitely good news, and after the start of operation, it can also significantly reduce the production cost, and it is estimated that the existing electricity bill can be directly reduced by nearly two layers, that is, the cost will be reduced by three to four points, which is too beneficial for the power plant, and it can make more than 200 million profits per year.

Now the profit of the power plant is actually quite limited, looking at the power generation is quite a lot, only tens of millions of profits per year, and the installation of a new generator set, the overall profit will be directly increased to nearly 300 million, after all, it is impossible to reduce the price of electricity now, this is directly formulated by the state, the country is basically unified, in this case, the profit of the power plant can be seen to rise in a straight line.

In this way, the inspection of the generator set began, and the next day some people carried out flaw detection tests on the boiler and inspected the condition of the relevant parts, while others began to test other components. For example, the operation test of the steam turbine, whether there is excessive vibration or dynamic balance problems, etc

, the ventilation cooling test of the coupling, the hydrogen cooling test of the generator, etc., there are various things that need to be tested, and they all need to be repeatedly tested and confirmed.

In this way, the test was carried out for half a month, and some basic tests could be carried out to wait for installation, but because it was the first time to design this kind of large-scale operation equipment, Li Zhao organized personnel to carry out multiple rounds of testing of all parts, mainly to prevent any problems in operation, and to solve the problem in the bud, so many rounds of detailed tests were carried out for the tests that could be carried out on each part.

It's just that now after all, it is impossible to directly carry out the operation test with load, so it is impossible to really show the performance of the equipment, so the role it can play is also limited, and if you want to really test the performance of the equipment, you can only wait for the actual operation after installation, and the current test is only to ensure that there are fewer problems during the actual test.

In this way, Li Zhao was busy testing the equipment here, and Su Ya's sister-in-law had a situation, yes, as the time approached July, Su Ya's sister-in-law was about to give birth, and on the 25th, when Li Zhao got off work and was about to get off work with Su Ya, he went to the office and pounced, and after inquiring, he found out that Su Ya's sister-in-law was about to give birth.

In order not to disturb Li Zhao's work, Su's father did not let anyone inform Li Zhao directly, and Li Zhao was really busy, testing the generator set here, and studying various problems in manufacturing with the turbofan engine project team from time to time.

Of course, slowness is relative, for now, in fact, it is very fast, almost next month, you can start assembling for related tests, and Li Zhao in order to save time, ready to directly carry out the operation test, the test of each part is directly omitted, of course, it is also to see whether the direct test is feasible, if it is not feasible, you still need to return to the test of each part, such as the air intake, compressor, combustion chamber, afterburner, tail nozzle, etc. In addition, it is necessary to test the strength and vibration of the parts.

The whole machine also needs to carry out ground operation test, high-altitude simulation test, environmental simulation test and flight test, now Li Zhao feels that time is tight, and wants to omit the test of each part directly, after all, he has tried to produce a relevant test, and finally carried out an ignition test, for the problems that arise in this process, he has optimized this time, so he wants to skip these directly.

If it can run normally, then he is ready to directly carry out the test of the whole machine, which can save a lot of time, which is why he directly built two for the first time, if the first one is directly scrapped, then the second one will carry out the relevant part of the test, find out the problem, if there is no problem, then there will be a direct afterburner test, one for the ordinary operation test, to speed up the progress of the test.

So Li Zhao is very busy, and this is also the reason, neither Father Su nor Su Ya let anyone inform him about this matter, until he got off work, he came to find Su Ya to get off work together, and he didn't know that there was such a thing, but this is a good thing.

Now not only Su Ya is not there, Su's father also went to the hospital, Li Zhao saw this situation and had to go home to see it first, this time today, the family must be in a mess, the reason is also very simple, several children have just finished the exam, waiting to get the notice for vacation, and now they are all waiting at home. As for not sending Li Zhao's nephews and nieces away, the reason is also very simple, Li Zhao's eldest brother and sister-in-law are busy now and have no time to take care of the children.

The current farm construction is basically in charge of Brother Li Zhao, after all, Father Li has been injured, although it is not usually very obvious, but it is still a little affected, now he is mainly responsible for the overall scheduling of each part, and the handling is in charge of Brother Li Zhao, in this case, how can they not be busy? And Li Zhao's sister-in-law needs to help Li Zhao's eldest brother organize women's work, so many people, eating and drinking are big problems.

Not only them, but Li Zhao's two brothers-in-law are also in the same situation, now they are busy every day, but they are enjoying it, they used to be just small staff, just working, but now the position is not high, there are many people in charge, and the person in charge of the project is still their father-in-law, this job is not easy to do.

As soon as Li Zhao got home, he smelled a strong smell

The fragrance of Li Zhao was a little dumbfounded just when he entered the house, and as soon as Li Zhao saw Li Zhao coming back, she said: "It's just right to come back, Xiaoya and her sister-in-law just gave birth to a daughter, you take care of the children at home, I'll send them food, I'll change Xiaoya back in a while, you eat and then go and see."

As he spoke, he stuffed Li Zhao's precious son into his hand, and then called four children, each with a basket, and set off directly, okay, they are all ready to be sent to the hospital, and there are a lot of things in this posture.
