Chapter 946: Be mentally prepared
When it comes to repairing machines, Han Yu is professional.
This is the first time for Han Yu to repair like this today.
The inspection found that the fault was not very serious. The weld between the steam pressure sampling pipe of the high-pressure regulating valve and the pipe seat was broken, causing steam leakage. It was necessary to seize the time to seal it.
Sealing is very simple, just weld it on, but the temperature of the steam is related to the pressure.
Under normal pressure, the temperature of steam is up to 100 degrees Celsius, but what is leaking is high-pressure steam, which is as high as more than 200 degrees Celsius, and it is continuously high!
Han Yu couldn't believe that his superiors didn't equip the officers and soldiers with heat-insulating protective clothing. He didn't even have heat-insulating protective hoods that looked like robbers. He could only wear fire-fighting suits with poor heat-insulating effect, in a steam-filled environment.
Emergency repairs are being carried out in the cabin.
A person can only work for a few minutes. If the time is longer, he will be burned. Even if he is not burned, he will faint from "heatstroke".
The pipes in the cabin were crisscrossed, which directly made it difficult for the rescuers to use their hands and feet.
And, here’s the cabin!
There are both steam pipelines, oil pipelines, and even electrical circuits.
To build such a national treasure, shouldn’t it take the entire country’s efforts?
If the quality is bad, can I blame you...
"Your big law enforcement rescue ships don't have daily inspection or monthly inspection records. They probably don't have any records either. It's convenient if you want to check them later."
"If you can contact me, you can arrange for someone to go to their unit to pick it up."
Han Yu understood the situation, immediately stopped the rescue, pulled the captain and the electromechanical chief aside, and formulated a blocking plan based on the situation on site. Under the premise of ensuring that no secondary accident would occur, the rescue personnel were divided into groups and took turns to go in and work.
.
Seeing the two chiefs hesitating to speak and looking worried, Han Yu thought about it and pretended to be nervous and said: "The bad thing is that without two main engines, it is very likely that they will malfunction at the same time. As long as we strengthen maintenance during the voyage, it will really be necessary."
If a malfunction occurs again, we will do our best to repair it. The mission should be completed and the problem should be small."
The captain finally breathed a sigh of relief and said quickly: "Han Xiao, he will go down and rest for a while, then you will organize the personnel to conduct maintenance."
Then we were sailing a thousand miles away when something like this happened.
Han Yu knew what the captain was thinking, and he didn't care what others thought. He looked back at the huge main engine and the criss-crossing pipelines, and said with a grimace: "Just now she passed by the steam turbine of Xiaolian Shipyard, which you thought was
The technology is very mature, but the manufacturing process must be very bad. It wasn’t until I participated in the emergency repair that I found out what the process is like, and even the raw materials and spare parts may be passable!”
As soon as Han Yu climbed off the bridge, an officer from multiple schools came to greet him: "Han Xiao, the commander-in-chief and the political commissar asked him to come over."
There were not two steam turbines, certainly only one. The entire warship would have been out of control!
"It was either 1941 or 1944. You forgot the specific year, but you guys took good care of it and it's still usable."
The hull is beautiful, but there are so few problems inside.
After a lot of work, we actually came up with such a project. Cold insulation protective equipment is so important, how can we not have it!
Confused about the situation, Chief of Staff Zheng breathed a sigh of relief and turned to look at Team Leader Shen.
The construction technology and quality of merchant ships are actually worse than those of warships!
"To be precise, it's you or your branch."
Han Yuzheng thought that it was wrong to ignore the development of the domestic shipbuilding industry, but in fact there is still no big gap between it and its international counterparts. Team leader Shen said with a wry smile: "Such a situation only happened under the Shenzhen ship, and it was for the troops stationed in Hong Kong. It also exists under the built Type 037 slow boat.
Han Yu dared to doubt that it was true, with a look of astonishment on his face.
Chief of Staff Zheng sat down without any fear and asked: "What are the hidden dangers?"
Team Leader Shen was equally depressed and said helplessly: "When the Shenzhen Zhenzheng was built, your military expenditures were at a historically high level. At that time, there were large orders for military products, and few military R&D and production units were already in full swing. "Does the boy have the task of producing military products? If not, he just maintains basic production."
"That's bad. He is an expert anyway, so he should be less careful."
"That's no wonder. It's the honeymoon period right now, and the blockade on you is as strict as it is now." Chief of Staff Zheng took a deep breath and asked: "Han, as he said, you are in great need now. Cold insulation protective equipment, these eight pieces of protective clothing from their unit, can they be lent to you first?"
Welding is an open flame operation, and fire safety must be taken into consideration. If the pipe where the steam leaks occurs is not blocked, but causes a fire in the engine room, then the trouble will be big, and the ship may have to be abandoned!
How to build small-tonnage ships in recent years? The main construction is merchant ships. The hull is welded, and the main engine and auxiliary equipment are all exported. Even if he wants to install the main engine with mature technology, the quality and economy are the same as those in the country. The shipowners will still want these two famous main engine manufacturing companies here even if you give them to them for free.
You are more vague than anyone about the importance of cold-insulating protective clothing, cold-insulating protective hoods, and even cold-insulating protective gloves. However, cold-insulating protective equipment that can achieve cold-insulating protective effects are all made of new materials. As far as you know, there are currently some in China. That technology has been blocked by the country. Not to mention that you can purchase it, even if you can purchase it, it will be cheap."
"If I have any questions, just contact your unit."
Han Yu was silent for a moment and said loudly: "Seven chiefs, you will write down the observation report on the problems you discovered. If she meets the seven of them again, they will not be mentally prepared." "There are no welds?"
The implication is not that what is maintained is bad.
Chief of Staff Zheng asked curiously: "When did he purchase these eight pieces of cold-insulating protective clothing?"
You can also blame the shipyard blindly, because for the shipyard, it is also a very happy thing. As the general contractor of the construction and the contract party B, we have to negotiate with the equipment and system production units, and a warship There are not tens of thousands of equipment supply units, so we cannot say that the decline in the quality of military products in those years was comprehensive, but only the shipyards."
Han Yu knew he was sweating a lot, so as soon as he came out, he put on his firefighting uniform with the help of the officers and soldiers, took a few sips of water, and said breathlessly: "Captain, you can still drive now, you It is recommended that all welds be inspected."
"Reporting to the head, it has been ruled out for the time being, but judging from what you discovered during the emergency repair, the equipment has many hidden dangers and needs a comprehensive and detailed inspection."
Many schools dared to suspect that the observer behind them who could repair machines actually dared to give face to the two chiefs. For a moment, they knew what to say and could only go back and report to the two chiefs.
Until this moment, Han Yu dared to doubt the problems discovered during the rescue operation and reported back in detail.
"Did he?" "Does he have a set?" "Where to go?" The electromechanical chief was in charge of the first group.
Just looking at the engine room, the quality of that warship is far worse than the freighters built by COSCO Kawasaki and Shenglong Shipbuilding in those years.
As the "user" of the warship, Chief of Staff Zheng was even more depressed. She said with a straight face: "Han, let me tell you another thing that he may dare to doubt. After the construction of the Shenzhen Ship, the Xiaolian Shipyard has not been there for ten years."
Have you ever produced such a low-power host!”
But then again, the new ships they build are all orders from domestic shipowners, and their use and even acceptance are in accordance with national standards. As for key equipment such as main engines and auxiliary engines, almost all of them are withdrawn. To put it bluntly, the shipyard is not building a ship.
shell.
The captain calmed down and asked his subordinates to send the observer away first.
"Send a few less sets. Do you know the cold-proof protective clothing he mentioned? Do you have one set?"
Because reform and opening up had not happened for many years at that time, and the shipbuilding industry was the industry with the lowest degree of openness, shipbuilding companies were fully integrated with international standards. In order to survive, they tried every means to improve their construction levels, compete with international peers, and go to international places to get orders.
.
Zeng Zhi paused and added: "Yes, the protective clothing you purchased is cold-insulating and flame-retardant. It is mainly used for firefighting. It is relatively light to wear under the body. It is this kind of professional military cold-insulating protective clothing."
.”
That Han Yu said, "Fang······convenient."
Zeng Zhizheng complained vigorously, and Team Leader Shen continued: "Because of the order, it directly led to a slight brain drain, a gap in technology, and a decline in quality. It also led to the emergence of quality problems in the construction of Shenzhen Zhengship. Salted fish, speak up.
Maybe he dares to believe it.
As soon as we left the large conference room and sat down, the commander-in-chief and the political commissar opened the door and left.
An hour had just passed, and Zeng Zhi was really tired.
"Chief is worried, from now on, you will leave the Shenzhen ship." Zeng Zhi suddenly remembered something and said quickly: "Chief, I almost forgot, why are there no cold-proof protective clothing and cold-proof headgear under the ship?
"Maybe you can contact the headquarters and ask the headquarters to send people to fly a few more sets to Malaysia as soon as possible."
Although Linghai is developing the ship machinery parts industry and has retired many related companies, it still has some technical content, such as hatch covers, gangways, etc.
Zeng Zhi was silent for a moment, then raised his head and said: "Chief, you don't have eight sets. Although there are more, it's still worse than nothing."
That observer is the same as the leaders and experts who will come to inspect and guide in the future. I really understand!
"Go to the command post."
After a few hours of easy repairs, the fracture was finally welded down.
"How did they purchase it?" Chief of Staff Zheng looked puzzled.
"Be prepared to repair the ship at any time, because one or another failure may occur at any time along the way!"
"Okay, they are busy, you go down first."
"You just go to the command post. You can go to the big conference room. The conference room is right next to the command post."
"I'm just afraid of the worst." Han Yu put down the tea cup and said solemnly: "Although you have been to the cabin a few times since then, you have only just glanced at it. I saw that the cabin was very clean, and you could almost see oil stains.
I thought the host was poorly maintained.”
That happens, and you know what happens next!
"Chief, you know what he wants to say, but there are no problems that can be solved by the electromechanical chief and the soldiers of the electromechanical team. The same can be solved by your mechanical engineering student."
Captain An, who was already worried because of such an accident, became even more worried and subconsciously looked at the electromechanical chief.
Chief of Staff Zheng said reluctantly: "If a steam leak occurs like this, the low temperature will continue outside the cabin. If there is a war, to say the least is auspicious, once it is hit by enemy artillery shells or missiles, there will be an instantaneous low temperature. It must be
In case of fire, it is necessary to direct and organize firefighting in low-temperature environment.
"What kind of mental preparation?"
"Xianyu, he is professional in that field and has rich experience. He is capable..."
When the Shenzhen Zhengzhou ship was delivered, your acceptance team checked out as many as 5,000 problems! Because of this, you accepted her, made rectifications within a time limit, and even initiated accountability."
Han Yu led the seventh group.
"Dahan, has the fault been eliminated?"
"From now on, in your Binjiang waters, there is only one professional law enforcement rescue boat from your old Yanjiang Police Station, which will be responsible for the underwater fire fighting tasks in the entire Binjiang section of the Yangtze River. At that time, you were short of funds, so you asked Bureau Feng to help exchange them into U.S. dollars, and entrusted
