Riverside Police.

Chapter 948 Be mentally prepared!

Han Yu is a professional in repairing machines.

It was the first time for Han Yu to repair like 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, resulting in steam leakage. It is necessary to seize the time to seal it.

The plugging is very simple, just weld it on, but the temperature of the steam is related to the size of the pressure.

Under normal pressure, the temperature of the 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 temperature!

Han Yu couldn't believe that the superiors didn't equip the officers and soldiers with heat-insulating protective clothing, let alone the heat-insulating protective hoods that looked like robbers, and could only wear fire-fighting clothing with poor heat-insulating effect. Carrying out repairs in the cabin.

A person can only work for a few minutes, and if it takes longer, he will be burned, and even if he is not burned, he will faint from "heat stroke".

The pipelines in the cabin criss-crossed, which directly caused the rescue personnel to be unable to let go.

And, here's the cabin!

There are both steam lines, oil lines, and even electric circuits.

Welding is an open flame operation, and fire safety must be considered.If the steam leaking pipe is not blocked and causes a fire in the engine room instead, then the trouble will be big, and the ship may be abandoned!

After Han Yu figured out the situation, he immediately stopped the emergency rescue, pulled the captain and the electromechanical chief aside, and formulated a blocking plan according to the situation on the spot.Under the premise of ensuring that no secondary accidents will be caused, rescuers are divided into groups and work in turns.

The electromechanical chief is in charge of the first group.

Han Yu led the second group.

After more than an hour of intensive repairs, the fracture was finally welded.

Han Yu didn't know how much sweat he was sweating. As soon as he came out, he took off his firefighting suit with the help of the officers and soldiers. Perform a single inspection of all welds."

"All the welds?"

"Don't be afraid of ten thousand, just in case." Han Yu put down his teacup and said solemnly: "Although I have been to the cabin a few times before, I have always been on a whim. I saw that the cabin was cleaned very clean, and there were almost no oil stains. Thought the host was well maintained."

The implication is that it is not well maintained.

The captain, who was already uneasy because of such an accident, became even more uneasy, and subconsciously looked at the chief electromechanical officer.

Han Yu didn't know 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 bitter face: "At first, I thought that the steam turbine technology of Dalian Shipyard was very advanced. Mature, the manufacturing process should be very good, until I participated in the emergency repair just now, I found that not only the process is not good, but even the raw materials and spare parts may not be up to standard!"

Can't blame us for the poor quality...

The captain finally breathed a sigh of relief, and quickly said: "Han Da, you go up and rest for a while, and I will organize personnel to overhaul."

"Our small law enforcement rescue boats have daily inspection and monthly inspection records, and you should also have them. I want to see them later. I don't know if it's convenient."

"Fang...convenient."

"Okay, you guys are busy, I'll go up first."

This observer is different from the leaders and experts who came to inspect and guide before, he really understands!

The captain settled down and hurriedly asked his subordinates to send the observers away first.

As soon as Han Yu climbed onto the bridge, a major officer greeted him: "Han Da, Commander-in-Chief and Political Commissar, please go over."

"where to?"

"Go to the command post."

"I won't go to the command post. Can I go to the small conference room? The conference room is next to the command post."

The major couldn't believe that the observer who was good at repairing machines dared not give face to the two chiefs. He didn't know what to say for a while, so he could only go back and report to the two chiefs.

In the past hour, Han Yu was really exhausted.

As soon as he walked into the small conference room and sat down, the commander-in-chief and the political commissar pushed the door open and entered.

"Xiao Han, is the fault cleared?"

"Report to the chief, temporarily ruled out, but judging from the situation I found during the emergency repair, there are many hidden dangers in the equipment, and a comprehensive and detailed inspection is required."

This failure occurred after sailing less than a thousand nautical miles.

This has two steam turbines, if there is only one, the whole warship will be out of control!

Chief of Staff Zheng had lingering fears, so he sat down and asked, "What hidden dangers exist?"

Until now, Han Yu couldn't believe the problems he found during the emergency rescue, so he reported them in detail.

After figuring out the situation, Chief of Staff Zheng breathed a sigh of relief, and turned to look at Team Leader Shen.

This happened and there was no telling what would happen next!

Team Leader Shen was equally depressed, and said helplessly: "When the Shenzheng ship was built, our military expenditure was at a historically low level. At that time, the number of orders for military products was small, and many military research and production units had no military products for many years. Some of the production tasks are only to maintain basic production."

If you only look at the engine room, the quality of this warship is far worse than the cargo ships built by COSCO Kawasaki and Shenglong Shipbuilding in recent years.

But then again, the new ships built by others are all orders from foreign shipowners, and their use and acceptance are all in accordance with foreign standards. As for the key equipment such as main engine and auxiliary machinery, almost all of them are imported. The shipyard simply builds a hull.

The construction technology and quality of merchant ships are actually better than those of warships!

Han Yuzheng was unable to complain, and Team Leader Shen continued: "Because there is no order, it directly leads to serious brain drain, technology faults, and quality declines, which also leads to quality problems in the construction of the Shenzheng Ship. Salt fish, speak out You may not believe it.

When the Shenzheng ship was delivered, our acceptance team checked out more than 5000 problems!Because of this, we refused to accept it, rectified within a time limit, and even initiated accountability. "

The hull is beautiful, but the interior has so many problems.

As the "user" of the warship, Chief of Staff Zheng was even more depressed, and said with a gloomy face: "Xiao Han, let me tell you one more thing that you may not believe. Powerful host!"

Han Yu believed this.

Because the reform and opening up had been going on for many years at that time, and the shipbuilding industry was the industry with the highest degree of openness. Shipbuilding enterprises were fully in line with international standards.

In those years, there were not many large-tonnage ships built. They mainly built merchant ships. The hulls were welded, and the host and auxiliary equipment were all imported. Even if you wanted to install a host with mature technology, the quality and economy were not as good as foreign ones. Even if you give the shipowner away for free, you wouldn't want those two famous main engine manufacturing companies.

Although Linghai is developing the ship machinery parts industry and has introduced many related companies, none of them have any technical content, such as hatch covers and gangways.

Han Yu was thinking that despite the fact that the domestic shipbuilding industry is developing well, but in fact there is still a big gap with international counterparts, Team Leader Shen smiled bitterly: "This kind of situation does not only happen on the Shenzheng ship, but also in the construction of ships for the troops stationed in Hong Kong. It also exists on the Type 037 speedboat.

We can't just blame the shipyard, because it is also a very painful thing for the contractor to build the shipyard.As the general contractor of the construction and Party B of the contract, they have to negotiate with the equipment and system production units, and there are thousands of equipment suppliers for a warship. It can be said that the decline in the quality of military products in recent years has been comprehensive. Just shipyards. "

Shouldn't it be the whole country's effort to build such an important weapon for the country?

After a lot of work, I actually came up with such a project.

Han Yu was silent for a moment, and said in a low voice: "Both chiefs, I will write the problems I found into the observation report, and you two must be mentally prepared."

"What mental preparation?"

"Be prepared to repair the ship at any time, because this or that failure may occur at any time along the way!"

"Salted fish, you are a professional in this field and have a lot of experience, can you..."

"Chief, I know what you want to say, but some problems cannot be solved by the electromechanical chief and the soldiers of the electromechanical team, nor can I, who is an engineering student, be able to solve them."

Seeing the two chiefs hesitant to speak and worried, Han Yu thought about it and said relaxedly: "Fortunately, there are two main engines, and it is unlikely that they will fail at the same time. As long as the inspection is strengthened during the voyage, if you really want to If there is a breakdown, we will do our best to repair it, and it should not be a big problem to complete the mission of the visit.”

"That's good, anyway, you are an expert, you should pay more attention."

"Don't worry, chief, from now on, I won't leave the Shenzheng ship." Han Yu suddenly remembered something, and hurriedly said: "Chief, I almost forgot, why is there no heat-resistant protective clothing and heat-resistant protective hood on the ship? Can you contact the headquarters, and ask the headquarters to quickly send someone to fly a few more sets to Malaysia."

"Send a few more sets. I know the kind of heat-insulating protective clothing you mentioned, but we don't have any."

"No set at all!"

Han Yu couldn't believe it was true, and looked shocked.

Chief of Staff Zheng said helplessly: "Steam leaks like just now, and the high temperature in the cabin will continue. If there is a war, it is unlucky to say that once it is hit by enemy shells or missiles, it will produce instantaneous high temperature. If you are not careful In the event of a fire, it is also necessary to direct and organize firefighting in a high-temperature environment.

We know better than anyone the importance of insulated protective clothing, insulated hoods and even insulated protective gloves.However, the heat insulation protection equipment that can achieve the heat insulation protection effect is made of new materials. As far as I know, this technology does not exist in China for the time being, and foreign countries have imposed a technical blockade on us.Don't say we can't buy it, even if we can buy it, it's not cheap. "

Heat insulation protective equipment is too important, how can we not have it!

Han Yu was silent for a moment, then raised his head and said, "Chief, I have three sets. Although there are fewer sets, it's better than nothing."

"You have?"

"To be precise, it's not mine, it's our bureau."

"How did you purchase it?" Chief of Staff Zheng looked in disbelief.

"In the past, in the Binjiang waters, we sent all the professional law enforcement and rescue boats along the river to undertake the task of fighting fires in the entire Yangtze Riverside section. At that time, we happened to have a little money, so we asked Feng Bureau to help convert it into U.S. dollars and entrusted a company to convert it into US dollars. purchased abroad."

Han Yu paused, and added: "However, what we purchased are heat-insulating and flame-retardant protective clothing, which are mainly used for firefighting. They are relatively bulky to wear, and they are not professional military heat-insulating protective clothing."

Chief of Staff Zheng asked curiously: "When did you purchase those three heat-resistant protective suits?"

"It's from [-] or [-]. I forget the exact year, but we have kept it very well and it is still usable."

"It's no wonder. It was the honeymoon period at that time, and the blockade against us was not as strict as it is now." Chief of Staff Zheng took a deep breath and asked, "Xiao Han, as you said, we need it very much now." Thermal protection equipment, can you lend us the three pieces of protective clothing from your unit first?"

"No problem, as long as we can contact our unit."

"If I can get in touch, I will arrange for someone to pick it up from your unit."
