Package the files and send them to Chen Luguang.
"Hello, Team Leader Chen, did you receive the document I sent you just now?"
"Got it, I'm looking at it. What the hell is this thing of yours? So many materials and blanks?" Chen Luguang asked curiously.
"Please help me check how many can be processed for me. I need it for an experiment." Liu Chi said vaguely.
"Doing experiments? You need so many? Are you kidding me? Are you making some kind of equipment?"
"Yes, I want to buy a set of equipment." Liu Chi changed the subject directly: "Please ask the higher-ups for me, can I buy four 'Taihu Lights'?"
"What? You want to buy four?" Chen Luguang put aside the matter of materials.
"Yes, four."
"Is it also for experiments?"
"right......"
"You're going to go to heaven, you want four at a time?"
"Please ask for me and we'll see if it works or not." Liu Chi was also helpless.
"I will report these two things to the higher-ups, but it may not be successful, especially since you want so much material." Chen Luguang felt that he had to give a reminder.
"I know. Just take what you have. Help me sort it out. Don't start production yet. Mark out the ones that are available. I'll figure out the ones that aren't available myself. Of course, it would be best if you could help me."
"Okay, but you have a lot of materials, so it will take some time to sort them out. I'll let you know when there's a result."
"Okay." Liu Chi nodded and asked, "How is Zhou Meng's case going? Is there any way to cure him?"
"There is hope, but it's not confirmed yet. We have to wait about two or three days for the results."
"Okay, let me know when there's a result." Liu Chi said happily.
Finally there is good news.
"Please pay attention to what I told you two days ago." Chen Luguang said.
"I know. I'll give it a try after I finish what I'm doing."
"good!"
"......" After Chen Luguang hung up the phone with Liu Chi, he took the materials and went to report to the boss.
As soon as Liu Chi hung up the phone with Chen Luguang, Jiang Yu called him.
"What's wrong, Jiang Yu?"
"Boss, Jiang Dinghong, general manager of Enron Electric, called just now and said that the rice cooker is basically ready, the production line personnel are in place, and the launch schedule can be brought forward."
"Produce 2.5 million core devices to our No. 9 Technology every month." Jiang Yu reported.
"You can arrange this. By the way, is the production line of our core device in place?"
"It's halfway in place, because the rice cooker production line is a bit complicated, and it will take about a month to get everything in place."
"Jiang Dinghong just said that the rice cooker commercial is ready to be filmed and he wants to invite Li Xiaoying. What do you think?"
"Li Xiaoying, it's up to her. I have no objection." Speaking of rice cookers, Liu Chi thought of Best Buy, and asked in confusion, "Didn't Best Buy take away 3.5 million sets of kettles before the New Year? How are they doing now? They haven't gone public yet?"
"According to the itinerary, it should have been in the hands of Best Buy, but I don't seem to have seen any relevant information." Jiang Yu added, "Best Buy has now added an order of 5 million. Starting from May this year, we will pay them 500,000 per month."
"Starting from May, 2 million sets were supplied to COFCO. Of the remaining 1 million, 500,000 were taken by the European Keck Group, and the last 500,000 were divided among a number of scattered companies."
"Is Keck Group so shameless? How many orders has he placed in total?" Liu Chi asked curiously.
"We paid 3 million yuan in full at once, and the price increased by 10%, which was considered as compensation for the last time," Jiang Yu explained.
"What about the rice cooker? How did Jiang Dinghong arrange it?"
"I didn't participate in the rice cooker business, but Jingxin Group received 500,000 yuan a month, and the rest is still under discussion. COFCO also wants a piece of the pie."
"It's only over 2.5 million a month, the amount is too small, not enough to share." Jiang Yu said helplessly: "They are arguing over there, and they banged the table a lot."
"Then leave them alone and let them handle it themselves."
"Okay, boss, should we also put the induction cooker on the agenda?" Jiang Yu said a little greedily, "After all, the company still has so many empty factories, and the rice cooker only occupies two factories."
"Since we cancelled the original Huahong order and the production lines are basically automated, we now have enough staff. We were too busy before, but now we don't have enough work to do."
"Well, let me think about it. You can ask Yuxin to come up with the design first."
"Okay, I'll talk to Manager Ye later." Jiang Yu said happily when he heard Liu Chi agree.
"......"
After Liu Chi hung up the phone, he could finally turn his attention to the motor.
The last time I was halfway through the experiment, I stopped because I had to manufacture the motor and bearings first, otherwise accuracy would be a big problem.
Only after the motor and bearings are repaired will we have time to deal with what Mr. Zhang said.
If the motor doesn't come out, the "automatic design system" can't work.
The last error was 0.5 grams 0.95.
If the motor accuracy is to reach 0.5UM, it should reach 0.3 grams.
Liu Chi disassembled the previous motor.
The balancing system needs to be readjusted and the rotor re-processed.
Magnetic field balance force.
Only when the balancing force of the entire rotor is uniform can you meet your requirements, and you also need to consider the issue of force.
If it is a physical drill bit, then when the drill bit hits the blank, force will be applied. If it exceeds the working range, the accuracy will change.
The processing accuracy must be high. If it is at high speed, friction heat and force problems will occur;
If there is an eccentric force, at high speed, the value of the centrifugal force is very large, which means that the work done is useless work;
This useless work will eventually dissipate in the form of heat, and also requires increased strength of the shaft, so it should be minimized. Therefore, the balancing system must have the ability to adjust the balance.
If you want to maintain accuracy.
Then the speed of the motor must be increased as much as possible.
According to the formula of centrifugal force and speed: F centripetal force = mrω^2 = mv^2r = mvw = 4π^2mrT^2
g=r×11.18×10-6×(rpm)2
r is calculated in cm;
The effective centrifugal radius is the rotation radius from the motor axis to the bottom of the centrifuge tube.
Conversion between speed and centrifugal force:
r is the distance between the center of the motor shaft and the inner wall of the bottom of the centrifugal casing;
rpm is the number of revolutions per minute of the centrifuge;
