Chapter 1500

Not only the executive deputy group leader, but almost all the others present were surprised by the weight parameter exposed by Zhuang Jianye, 27 tons, less than half of the total weight of da-80t.

What does that mean?

If d-71m gas turbine is adopted, the equipment platform with reinforced concrete and mechanical support mechanism built according to high standards is completely unnecessary.

After all, a device of nearly 60 tons and a device of less than 30 tons are completely different in vibration and stability.

Therefore, once the d-71m gas turbine is adopted, the expenditure of the second phase of West to east gas transmission project will be saved by more than 500 million yuan.

You know, it's 74 high standard equipment sets, even if it saves half, it's 250 million.

This is undoubtedly good news for the west to east gas transmission project with huge investment. After all, the state is very strict in the audit of this project, and every penny of overspending should be clearly explained and recorded for the record; If you can save, there will be corresponding rewards.

Because of this, the project team, from the leaders to the ordinary staff, are all worried about spending more money, but once there is an expectation of saving, they are as happy as changing individuals.

Of course, the most vigorous is the Deputy group leader. The total weight of 27 tons is equivalent to the rated tonnage of da-80t reserved for the destroyer, which can directly house two d-71m gas turbines.

This is unimaginable for the integrated and efficient use of space of destroyers.

That's all. The key is that the total weight of 27 tons is more adaptable. Not to mention destroyers of more than 5000 tons, frigates of about 2000 tons, d-71m gas turbines can meet the demand.

This is not only good news for the Navy, but also good news.

Some people are happy, others are sad.

A large number of friends and businessmen, such as Shen Zong and oginlike, were stunned when Zhuang Jianye said that the d-71m gas turbine had a total weight of only 27 tons, and immediately scolded flowers in the bottom of his heart.

Ashamed... Ashamed wool!

Zhuang Jianye is ashamed of 27 tons. Should we over 50 tons commit suicide on the spot?

Why don't you do that!

Of course, many people still don't believe in scolding. After all, they are senior people in the industry. It's difficult to control the weight of 20 MW gas turbine with sound insulation overall box, base with shock-absorbing float valve and a full set of control and monitoring system.

Therefore, many people privately speculate that the d-71m gas turbine on the truck is not complete, but lacks some equipment, otherwise it will not be so light.

For example, President Shen said to other friends: "if we remove the base of our da-80t, we can also achieve the level of 30 tons. What's the big deal? It's a mule or a horse, and we have to go on the test bench and walk well."

Instead of focusing on the weight of the d-71m gas turbine, oginlike focused on the power: "The key is to look at the power. If it is less than 20 MW, Zhuang Jianye will be embarrassed this time. You know, the weight of each kilogram of our high-power gas turbine is not wasted. Finally, it is all reflected in the power. The 27 ton weight of d-71m gas turbine is indeed experienced. The question is, who is stronger and more obvious, a malnourished guy or a fierce man with muscle explosion It goes without saying... "

Whether it's citric acid or envy, envy, jealousy or hate, Shen and aojinlake's words still make sense to people in the industry. Over the years, there are really many products with bright parameters, but there are none that can really fight. Even some pull their crotch so that even many people in the industry feel blushed.

The project team of West to East Gas Transmission knows this truth, and the executive deputy leader who has been transferred from the Navy knows it better.

Therefore, after a brief exchange of greetings with Zhuang Jianye, the relevant lifting work of the project team was ready, but a 30 ton crane subordinate to the project team easily lifted the d-71m gas turbine on the truck, and the people on the site fell to the ground.

D-71m gas turbine is really less than 30 tons.

Of course, President Shen's face in this scene is very ugly, because his assumption that the d-71m gas turbine is incomplete is broken.

At the moment of crane lifting, the base of d-71m gas turbine equipped with mechanical damping float valve was clearly exposed.

Unlike the shock-absorbing float valve base made by other friends, the overall compactness of the shock-absorbing float valve of d-71m gas turbine is particularly high. In addition to the mechanical shock-absorbing float valve in the outer layer, a shock-absorbing isolation layer supported by special rubber is also set inside.

However, the double-layer damping structure is less than 30 tons, which is not as simple as controlling the product integration force and details, but a comprehensive rolling in the high-end fields of materials, processes and system integration.

It is not only the crushing of the Aviation Development Corporation, but even Ge. If it is only at the level of ge-2800, it is also pressed on the ground and rubbed desperately.

Of course, this double-layer damping setting falls into the eyes of the executive deputy group leader, that is, the more mother-in-law looks at her son-in-law, the more satisfied she is.

We should know that a key index on military ships is noise control.

One is to be discovered by an underwater submarine; Second, it is also to avoid interference with sonar and improve the detection distance and accuracy of its own sonar.

Because of this, military ships have a very strict shock absorption control on the power system, which requires not only the power package itself to have shock absorption and sound insulation devices, but also a layer of shock absorption mechanism to be installed at the position of the power system during hull construction to offset the possible noise.

Under the condition of excellent weight control, d-71m gas turbine is equipped with double-layer damping mechanism, and the noise control effect is naturally much better than da-80t, which is equipped with only one layer of ordinary mechanical damping float valve.

However, satisfaction is satisfaction. The executive deputy group leader also knows that no matter how good the surface parameters are, if the core power does not pass, everything will be in vain. So he personally speeds up the hoisting and commissioning progress, just like a child who gets his favorite toy. He wants to install the battery immediately, pull out the remote control wire and play directly, I can't wait to burst the d-71m gas turbine power meter in the next second.

"There's an old saying in China that smart people are mistaken for smart people. Is that what you're talking about?" oginlike asked President Shen with a smile when he saw that the executive deputy group leader couldn't wait.

President Shen glanced at the corner of his mouth: "I prefer to describe it by lifting a stone and hitting my own feet!"

As soon as the words fell, they looked at each other and smiled. Everything was silent, because under the deployment of the executive deputy group leader, the installation and hoisting work was very fast. Within less than an hour, the d-71m gas turbine was put on the test bench, and the oil pipes, cables and main shafts were quickly connected. With the engineer's order, the d-71m gas turbine was started.

Soon, the power soared to 18 MW, and in the twinkling of an eye, it rose to 25 MW. However, all this did not mean to end. The power continued to rise, 26 MW, 27 MW, 28 MW... Until it was fixed at 32 MW, the d-71m gas turbine stopped soaring.

At this time, the executive deputy group leader's breathing was hurried: "President Zhuang, can your d-71m gas turbine achieve 30 MW?"

Zhuang Jianye smiled modestly: "I wanted to be a 20 MW, but I didn't expect to work to 30 MW accidentally!"
