Divorce in middle age: starting with the manor system

Chapter 273 270, impact type and counterattack mixed flow type
"Two are impulse turbines, and the other is a counter-impact Francis turbine," Wu Qingfeng said.

"???" Mr. Wu just felt confused.

Wu Qingfeng shook his head immediately, patted his cousin and said with a smile: "In short, it's right if there is no wrong delivery. You can understand it as two models."

"Oh!" Wu Qingnian nodded, then continued to watch!
I didn't get to the bottom of it, because to Wu Qingnian, shock and counterattack were technical terms at first glance, so he wasn't interested.

As long as it can generate electricity.

Anyway, if my cousin said yes, then there is no problem.

Wu Qingfeng smiled.

Wu Qingnian didn't understand, even if he explained it, he couldn't understand it for a while.

The reason why he chose two turbine operation modes is mainly for the consideration of the power station itself.

When the water storage capacity of the reservoir is insufficient, two impact turbines can be used to generate electricity, and the water storage capacity is sufficient. For example, from July to October, during the rainy season or heavy rain season, the counter-impact Francis turbine generator set can be turned on.

Because of the impact Francis turbine, the utilization rate of water energy is relatively high.

If it wasn't for the fear of insufficient water, he would have wanted to replace all of them with counter-impact Francis turbines, because the power generation efficiency and water head utilization rate are much higher than those of impulse turbines.

For example, the Three Gorges Dam uses counterattack Francis turbines.

Of course, the Pelton turbine is not useless. It is very suitable when the ratio of flow to water head is relatively small. In addition, the weighted average efficiency is very high, and it has a high efficiency in the entire operating range, basically at 30%. ~110% load range can average over 91% efficiency.

In addition, the ability to adapt to changes in water head is relatively strong, and it is also very adaptable to pipes with a large ratio of water head.

That is, the efficiency of power generation and the use of water head are not as good as counterattack Francis turbines.

Anyway, each has its advantages!
This is why Wu Qingfeng bought two types of water turbines.

……

After five o'clock in the afternoon, the installation of the three hydroelectric generating units was completed.

"Thanks for your hard work, Mr. Wang!" Wu Qingfeng said sincerely as he looked at the engineer Wang Lei and five technicians who were washing their hands, looking at the terminal building that had changed greatly.

From [-] o'clock to now, Wang Lei and the five technicians have not rested for a moment except for drinking water.

"Mr. Wu, you're welcome. You are a customer. It's our duty to help customers install it." Wang Lei wiped the sweat off his face with a towel and said with a smile.

"Wang Gong, I'll be the host later, let's go to the town and find a place to eat." Wu Qingfeng laughed.

"No, no, Mr. Wu, we have to rush back to Xi'an while we have enough time, so we don't need to eat!" Wang Lei shook his head quickly.

"Here, it's getting late. Let's have a meal, rest for a night, and go back tomorrow!" Wu Qingfeng continued.

"I'll pay the fee!"

To be honest, although he was just helping hands with other workers during the installation process, he could also feel Wang Lei's hard work, especially the turbine pit, which was not high and had to bend over all the time.

"Here... Mr. Wu, you can eat, but you won't have to stay, we have to go back today.

Otherwise, it will violate the company regulations! "Wang Lei laughed.

"Okay, let's eat!"

After Wang Lei and the others finished washing, Wu Qingfeng followed Wang Lei and the others to visit the completely installed airport station building and dam.

After visiting along the way, Wu Qingfeng looked at Wang Lei beside him with a smile, and asked, "Wang Gong, from your professional point of view, there shouldn't be any major problems with the design of this hydropower station, right?"

"President Wu, there is no major problem!" Wang Lei was taken aback for a moment, then smiled.

"Really?" Wu Qingfeng asked again.

"Brother, everyone said it's all right, why do you still ask, don't you trust my construction technology?" Wu Qingnian grinned and said dissatisfied.

"You guys won't forget, those little troubles during the installation before, right?" Wu Qingfeng looked at his cousin angrily.

Before, this guy swears that there is no problem.

However, during the installation, small problems continued. In various places, the cement drilled out with an electric hammer weighed hundreds of catties.

Fortunately, the manpower was sufficient, and the installation couldn't be done here, so Wang Lei moved to another place and continued to install other units, and quickly asked the workers to chisel them out with electric hammers.

Fortunately, it's a small problem, otherwise it would be absolutely impossible to complete the project in six hours.

"That's just a small daydream!" Wu Qingnian blushed. After the installation, there were no major problems, but there were indeed many minor problems.

"Actually, Mr. Wu, there is no need to criticize Mr. Wu. This is the first time he has designed and constructed by himself, and it is already very good!" Wang Lei laughed.

When chatting before, he knew the relationship between Wu Qingfeng and Wu Qingnian, so he also knew that the two were joking, so he interrupted.

"We used to install for other customers. There were no drawings at all for the foundation pit of the water wheel and the waterway, and some of them were not even the same as the drawings." Wang Lei laughed.

Wu Qingfeng nodded, then looked at Wang Lei with a smile: "Wang Gong, so there is no big problem?"

"no!"

"Mr. Wu, I guarantee with my personality that there is no problem. You should know that I am responsible for installing the machine. If something goes wrong in the end, I will take responsibility!"

"Besides, it has already been installed, which means there is no problem. If there is a problem, it can only be a problem with the machine itself!" Wang Lei assured with a smile.

"That's good. It's not that I don't believe in Wang Gong, but that I invested a lot of money in this power station. I can't bear it if something goes wrong with my small business!" Wu Qingfeng laughed.

"I understand that if the water storage is enough, it would be good to test the machine itself, but unfortunately, the water in the reservoir is not enough!" Wang Lei laughed.

He can guarantee that Wu Qingnian's power station is qualified, but he can't guarantee that there is no problem with the machine.

Because he is not an engineer of the manufacturer, he does not know the specific problems of the machine.

But now it's not possible to test here either!

"As long as there is no problem with the design, the problem with the machine is another matter!" Wu Qingfeng laughed.

He is not afraid of machine problems, because the purchase of these three hydro-generator sets is paid in three stages, the deposit, the mid-term installation payment, and the final payment.

After the machine is installed, within three months of operation, if there is no downtime problem with the machine, he will pay the final 30.00% final payment after three months.

The three 500 million-kilowatt hydroelectric generating units cost a total of 65 yuan, which was supposed to cost 70 yuan, but he bought three, and the agent offered a lot of discounts.

So he is not afraid of problems with the machine.

Wang Lei nodded, while Wu Qingnong curled his lips and said, "Brother, do you believe that I am still strong now?"

"It's okay, keep up the good work!" Wu Qingfeng patted his cousin.
