Chapter 285: Full electric propulsion

Boring call.
Call Huang Ruoxi. See what she is doing.
As a result, it was Chu Yulan who answered the phone.
"Dear husband, what are you doing?" Chu Yulan said deliberately, "Did you miss us?"
"Yeah! I missed you all by myself last night!" Wang Bu'an said.
"I really want to go back and warm your bed! But my sister won't give it!"
"Then you talk about it!"
"Hey, I respect my sister the most."
"what is she doing?"
"I ran for a day yesterday and was exhausted."
"How about you?"
"I'm tired too. But you don't care about me. I'm a bit jealous."
"Then come back to Yucheng, I care about you every day."
"I do not want it."
"Then you say fart!"
"No swearing. I turned on the speakerphone."
"you……"
Wang Buan suddenly understood that he had been fooled.
It is estimated that Huang Ruoxi was listening by the side. Intentionally let Chu Yulan come to tease him. See how he reacted.
Who said Mr. Huang couldn't understand the customs?
It's just that her style is difficult for outsiders to understand.
Sure enough, after a while, Huang Ruoxi spoke, "Strange, that Fang Yuqing didn't stay with you overnight?"
"No!" Wang Bu'an said, "She was forced away by Bai Kenan."
"Who is Bai Kenan?"
"It's the man who can get rhinitis when he sees beautiful women."
"Oh, I remember."
"Hey, it's him!"
"It's true that things are gathered by kind, and people are divided by groups. By your side, you really gather all kinds of heroes from all over the world!"
"What can I do? No one else is taller than me. I can only fool around with a bunch of crooked melons."
"Are you saying that I'm also crooked?"
"No, no, no. Absolutely not. I was wrong."
"Hmph, don't say that next time. I am not Huang Ruoxi, neither is you Wang Bu'an."
"Know, know."
"By the way, Bronck and Ferrodi are both eyeing you?"
"Huh? How did you know?"
"What do you mean?"
"Oh. They also reported to you."
"Yes."
"Do you have any suggestions?"
"Fighting lawsuits upright. We will stay with them for as long as they want."
"it is good!"
Wang Bu'an clapped vigorously.
Huang Ruoxi is good. The future lawyer Huang will have hard bones.
Not afraid of things.
Don't flinch.
Bong to the end.
The brave wins when meet on a narrow road.
"After the matter in Sacheng is over, I will go back." Huang Ruoxi said firmly, "When the time comes, I will be responsible for the lawsuit!"
"Okay. Before that, I will touch their bottom first." Wang Bu'an said.
The two negotiated and decided, and then hung up.
Wang Bu'an lay in bed for a while before he got up limply.
Wash your face.
wear clothes.
Come down for breakfast.
I met an acquaintance unexpectedly in a western restaurant.
Who?
Convince people thunder tiger with virtue.
Looking around, there is only one person in Thunder Tiger. Looks a bit depressed.
its not right!
His order has already started production.
Wang Bu'an promised that the order of Thunder Tiger will be completed in the shortest time.
"Boss Lei, what are you doing?"
"Drinking."
"Dropped in love?"
"I practice Tongzi Gong!"
"Do you think anyone will believe it? Give it back to boyhood?"
"Whether you believe it or not. Anyway, what I practice is Tongzi Gong. I definitely can't be close to women."
"Why are you so depressed?"
"I didn't get a list recently. Not reconciled."
"What list?"
"Copper motor."
"You still make copper motors?"
"Do it! It's a pity that your Tyrannosaurus Rex Industry does not have a copper motor. Otherwise, I will definitely take this list."
"What a big list? It's so frustrating, as for?"
"Three numbers."
"Three hundred million dollars!"
No wonder Thunder Tiger is so depressed. The amount of dare to order is really huge.
Thunder Tiger is actually a broker. It's just that the scale is bigger than Hu Sanniang, with more channels and more customers. However, no matter what, only by getting the order is the foundation of survival.
In the international market, there are so many brokers, so few orders, and too many monks and little meat. It is not easy to get them.
That is to say, Thunder Tiger is so fierce that he barely managed to get a bit of status.
This is the blessing of Tyrannosaurus Rex Industry.
However, domestic orders for motors are not really dominant.
The main issue is the price of copper.
Motor coils require high-performance copper alloys.
Our country is already short of copper. Copper alloys need to be imported. As a result, domestic copper prices are always higher than those abroad. The competitiveness of copper products is not strong.
In addition, the domestic motor manufacturing technology does not have an advantage in the international arena.
There is no advantage in price, and no advantage in quality. Of course, it is not easy to get an order.
"How much power?"
"50, 500, 5000 kilowatts."
"It's quite powerful!"
"Yes! Domestic quotations are very high! The quality is average. Foreigners have high requirements."
"Who did the last order go to?"
"Mitsubishi."
"Oh."
Wang Bu'an sat down.
He poured a cup of tea for Thunder Tiger.
I also poured myself a cup of tea. Serve up and taste slowly.
Motors and bearings can be said to be mechanical parts. Still very important mechanical parts. It is the foundation of power machinery.
The difference is that the motor itself can also be regarded as a set of machinery, a consumer product.
In the field of electric motors, Mitsubishi is indeed the leader.
The second place is Yaskawa. It is also a company from Dongying.
The third place is Wolong.
The fourth place is Panasonic.
The fifth place is ABB.
The sixth place is Siemens.
The seventh place is Dayang Electric.
The eighth place is Jiang Te.
The ninth place is Dechang.
Ranked tenth is Delta from Treasure Island.
The technology of manufacturing electric motors is simple and simple, including the main components such as the stator, rotor, coil, and bearing.
Any worker can make it with a few pieces of iron and a few coils.
But to say it is complicated and complicated. How to make these simple parts the best. It requires hard work and research.
Fortunately, we are not behind. The third, seventh, eighth and ninth are all mainland brands.
The problem is that Mitsubishi Electric's advantage is really great.
High-level motors are almost all of Mitsubishi's. none of them.
The premiums of brands such as Yaskawa, Panasonic, and Siemens are also amazing. They robbed most of the profits in the electric motor market.
For example, among the most common air conditioners, high-quality air conditioners use Mitsubishi Electric.
Especially for DC inverter air conditioners, Mitsubishi Electric occupies a large proportion.
"Boss Wang, or else, you can also get an electric motor." Thunder Tiger was whimsical.
"But, I don't even have enough bearing capacity now." Wang Bu'an frowned and said, "Going to the electric motor again? No manpower and equipment!"
"There will definitely be. Even if it is not currently, there will be in the future." Thunder Tiger tried his best to encourage.
"You seem to be very eager?" Wang Bu'an asked meaningfully.
"Eager! Of course eager!"
"why?"
"Hundreds of billions of dollars in market share, are you not going to get a share of the pie?"
"Ha ha."
"Among them, the automotive electric motor market alone is more than 40 billion U.S. dollars. Don't you feel like it at all?"
"Ha ha."
Wang Bu'an was really not moved.
In this electric motor market, the cake is really big. But the competition is also fierce.
Profits are not so easy to earn.
If it is not necessary, he is reluctant to intervene.
However, what's so immortal is that this electric motor happens to be in the road map he designed!
For construction machinery, hydraulic pressure, bearings, electric motors, and power are the indispensable main components. Failure to pass any system may lead to final defeat.
Three years later, he will come up with the most powerful shield machine to block other people's mouths.
Is he assured of letting others produce parts?
Of course don't worry!
The key components must be produced by themselves.
Among them, it includes various types of motors. There may be many motor models that need to be used on a shield machine.
Different drill bits are matched with different motors.
Different hydraulic systems also need different motors.
There are also systems for pumping, dredging, conveying, grouting, grouting, curing, guiding, and wall laying, etc., and motors are also needed.
If you look a little longer...
Car motor...
Ship motor...
Submarine motor...
One of the most popular words now is all-electric propulsion.
It is to convert all energy into electricity. Then take the electric drive approach. It can save energy, reduce noise, strengthen mechanical structure, etc.
What are the benefits of all-electric propulsion?
The first advantage is to facilitate the design of the hull structure.
Traditional power propulsion must rely on the drive shaft. This drive shaft traverses the main body of the ship, which brings many disadvantages.
The first is that it is not well sealed ~EbookFREE.me~ and the second is that the space will be wasted.
Thirdly, the efficiency of the drive shaft is not high. The length is limited.
Again, the noise is not easy to solve.
If this drive shaft is cancelled, the design of the hull will be more free.
The diesel engine can be placed on a liquid floating raft, which greatly reduces vibration and noise. The cable is soft and easy to arrange without affecting the watertight compartment. The speed of the motor is very easy to adjust. Even if you want to reverse the operation, it is very simple. In this way, the transmission is unnecessary. It saves space again.
For warships, the benefits here are irresistible.
With the development of the current trend, the warships of various countries have also made great strides towards all-electricity.
It is estimated that in the near future, the tank will also adopt all-electric propulsion.
The second advantage is higher utilization efficiency. Conducive to the centralized distribution of energy.
Still use the ship as an example. If you advance at full speed, you can gather all the electricity and supply all the propellers to ensure the speed.
If it is going slowly, just turn on a diesel engine with the smallest power to generate electricity.
In this way, there will be more freedom in power and fuel control.
Through scientific calculations, fuel can be greatly saved and the total range can be increased.
The third benefit is to shorten the construction period.
Each component can be produced in advance and then assembled together.
Soft connections are also used in each section. There is no influence of the drive spindle. Welding and splicing between each other is naturally much easier.
From this perspective, the quality of the motor is related to the fundamental quality of the machine.
It represents the future development direction of power machinery!
It seems that I must pay attention to it.
