"I want to go with you."

"Girl, stay at home well." Liu Chi gently hugged Ye Yuxin and said: "I will be back soon and will pay attention to safety."

"No..." Ye Yuxin was surprisingly stubborn at this time: "Don't worry, I won't disturb you."

"Then quickly change clothes, don't wear skirts and high heels."

"Ok!"

"..."

Speeding up all the way, half an hour later, Liu Chi and the two came to the company laboratory.

"Girl, stay, if it's okay, help me pay attention to relevant news on the Internet and see if there are any emergencies." Liu Chi said while playing the computer.

"Ok!"

"By the way, if you ask your uncle, it is not convenient for Fang to send a helicopter over, so that you can save a lot of time on the road." Liu Chi said without looking back while operating the computer.

"Okay!" Ye Yuxin took out her mobile phone from her bag, and walked out of the laboratory for fear of disturbing Liu Chi.

......

80,000 revolutions?

Two valves, that is 160,000 turns.

If it is closed for two hours, it will take at least 1333 revolutions in a minute, plus the force, the initial speed must be at least 1500 revolutions.

With robot hands, that is impossible.

The best way is to automate.

Liu Chi's brain moved, if the robot holds a motor in his hand, the speed of the'circle' can definitely meet the requirements.

So now you have to calculate the output power yourself, and how to ensure the normal work under the high temperature of 2300 degrees, and ensure the balance of the robot in the air, but if it can work, there is no problem.

The formula for calculating the output power of the motor is: P≈TN9549

T is the torque and N is the speed.

The formula for calculating the input power of the motor is: P=UIcosφ.

Among them, U is the voltage, I is the current, and φ is the phase difference between the phase voltage and the phase current.

therefore......

......

When the number of pole pairs is 2, the speed of the rotating magnetic field is n=1500.

n=60fp;

n——Rotation speed of the motor (revolutions); 60——Per minute (second); f——Power frequency (Hertz); p——The number of pole pairs of the rotating magnetic field of the motor.

The standard power frequency is specified as f=50 cycles per second.

Due to the slip rate, the actual speed of the motor is slightly lower than that of the rotating magnetic field. In the frequency conversion speed control system, according to the formula n=60fp;

Known...

Changing the frequency f can change the speed and reduce the frequency f, the speed becomes smaller:

That is, 60fp=n increases the frequency f, and the speed increases: that is, 60fp=n.

......

So when P exceeds 12.8, then there is no problem!

Liu Chi instantly opened a folder on the computer screen.

The hand speed soared continuously.

Ten minutes later, Liu Chi wanted to plug a USB flash drive into the computer's USB port.

"Data is being copied, please wait..."

"Yu Xin, help me get a few A2 buckles." Liu Chi saw Ye Yuxin beside him and said directly.

"Okay!" Ye Yuxin replied and ran out of the laboratory'cengceng'.

......

While Liu Chi was busy, a helicopter hovered directly above the industrial park.

"Can you land?" Chen Luguang on the plane looked around, and finally asked the captain with a speechless expression on his face.

"I don't know if I can withstand the strong wind from the helicopter in the square below."

"I'll make a call first." After Chen Luguang took out his mobile phone from his pocket, and read out Liu Chi's number, he was about to press the dial button, but after thinking about it, he stepped out and found out Ye Yuxin's phone number.

"Uncle? Are you here?"

"I'm over your industrial park."

"It's okay, you get down first, it's okay." Ye Yuxin naturally knew that Chen Luguang was afraid that the buildings in the square could not stand the strong wind from the helicopter.

"Okay, then I'm going down." After Chen Luguang hung up the phone, he glanced at the square field below his eyes, said to the captain with his heart, and descended in the middle of the square.

"..."

"How about, what did Liu Chi say?" Chen Luguang directly asked Ye Yuxin, who was approaching him, anxiously after getting off the helicopter.

"I don't know yet, he is still doing a side test." Ye Yuxin said comfortingly: "Don't worry, I believe Liu Chi can do it. Uncle, you should come to his office for a rest first."

"Okay." Chen Luguang looked up at the brightly lit fourth floor and prayed: It must be possible!

Ye Yuxin took Chen Luguang to Liu Chi's office, poured him a glass of water, and said, "Uncle, you are waiting here, I will have a look at the laboratory."

"it is good."

After more than ten minutes, Liu Chi walked down with a robot that was nearly half a meter away, and Ye Yuxin, who was holding a notebook, followed behind.

"how about it?"

"The test should be no problem, but you have to go to the site to try it." Liu Chi said directly: "Let's go, time is tight."

"Good!" Chen Luguang stood up cleanly.

"..."

"Did you get a robot in such a short time?" Chen Luguang followed Liu Chi in surprise.

"What do you think, you treat me as a god. This was a technique I made some time ago to verify a technique, and it just came in handy today." Liu Chi explained,

"What is this on the surface of the robot? So many patterns." Chen Luguang was hung up with curiosity.

"Confidentiality..." Liu Chi handed the robot in his hand to Chen Luguang and said, "Help me take it down. I want to call the disaster area and let them prepare something for me."

"Okay!" Chen Luguang took the robot and looked at the pattern on the surface curiously. Aside from anything else, it looked pretty.

Ok!!!

There is a bit heavy, about 20KG.

Liu Chi opened the call log, found the number that Li Ang had just called, and called out.

"Hello, Mr. Liu? How can I do it?"

"After the test, it's okay, but I need to go to the site to try it. You help me prepare something, I will use it later."

"Good, good, what do you want me to say?" Commander Li would finally hear the first good news, and he was so happy that he was a little bit vocal.

"Help me prepare an'Anhong brand model SS-500' motor, and help me wrap the entire motor with high heat-resistant materials to ensure that the motor can work for more than one hour under high temperature conditions. Of course, the longer the better. ."

"There is also a heat-resistant material about 500mm long welded to the head of the movement. It is best to conduct heat weakly. The front end is made of a three-leaf buckle. I will pass it into the disc that closes the valve."

"One more point, it is very important that the weight of the entire motor cannot exceed 15 kg."

"If there is enough time, it's best to prepare two more. I'm afraid the motor won't stand the temperature, so make two more as a spare."

"Understand, I'll let someone arrange it right away."

"I'm leaving from Yanjing now, and I'll take a helicopter. I will arrive in about half an hour."

"Okay! Please trouble Mr. Liu." Chen Luguang lost his heart.

"..."

"Girl, can you sit?" Liu Chi looked at the helicopter in front of him, and looked at Ye Yuxin beside him a little worried.

"It's okay, I've been there." Ye Yuxin finished speaking and walked to the helicopter in the middle of the square.

"Uh......"
