Chapter 285: All-electric propulsion
Boring calls.
Call Huang Ruoxi. Look at what she's up to.
As a result, it was Chu Yulan who answered the phone.
"Kiss your husband, what are you doing?" Chu Yulan said deliberately in a snort, "Do you miss us?"
"Yes, I couldn't sleep alone last night, I miss you so much!" Wang Bu'an said.
"I really want to go back and warm your bed!
"Then you talk about it!"
"Hehe, I respect my sister the most. ”
"What is she doing?"
"Yesterday I ran all day and was exhausted. ”
"What about you?"
"I'm tired too. But you don't care about me. I'm a little jealous. ”
"Then when you come back to Yucheng, I care about you every day. ”
"I don't want it. ”
"Then you talk!"
"Don't swear. I've turned on hands-free. ”
"You ......"
Wang Bu'an immediately understood that he had been fooled.
It is estimated that Huang Ruoxi is listening to it. deliberately let Chu Yulan tease him. Let's see how he reacts.
Who said Barrister Wong was incomprehensible?
It's just that her style is difficult for outsiders to understand.
Sure enough, after a while, Huang Ruoxi spoke, "It's strange, that Fang Yuqing didn't spend the night with you?"
"No!" Wang Bu'an said, "she was forced away by Bai Kainan." ”
"Who is Kenan Bai?"
"It's the man of God who gets rhinitis when he sees a beautiful woman. ”
"Oh, I remembered. ”
"Hey, that's him!"
"It's really like things gather and people are grouped. Around you, there are really all kinds of heroes gathered from all over the world!"
"What can I do? No one else is taller than me. can only fool around with a group of crooked melons and cracked dates. ”
"Are you saying that I'm also a crooked melon and cracked jujube?"
"No, no, no. Definitely not. I was wrong. ”
"Hmph, don't say that next time. I, Huang Ruoxi, am not crooked melons and cracked dates, and neither are you, Wang Buan. ”
"Yes, yes. ”
"By the way, both Blanc and Ferodi have their eyes on you?"
"Huh, how do you know?"
"What do you say?"
"Oh. They also reported back to you. ”
"Yes. ”
"What do you suggest?"
"It's a dignified lawsuit. We will be with them for as long as they want. ”
"Good!"
Wang Buan applauded vigorously.
Huang Ruoxi is good. The future Barrister Huang is hard-boned.
Don't be afraid.
Don't hold back.
Accompany you to the end.
When the narrow road meets, the brave wins.
"When the incident in Sa City was over, I went back. Huang Ruoxi said firmly, "When the time comes, I will be responsible for the lawsuit!"
"Good. Before I do that, I'll get to the bottom of them. Wang Buan said.
The two discussed before hanging up the phone.
Wang Buan lay on the bed for a while before he got up.
Wash.
Get dressed.
Come down for breakfast.
I unexpectedly met an acquaintance in a western restaurant.
Who?
Serve people with virtue and thunder tigers.
Looking around, there was only one person in Lei Laohu. He looked a little depressed.
That's not right!
His order has already begun to be produced.
Wang Buan promised that Lei Laohu's order would be completed in the shortest possible time.
"Boss Lei, what are you doing?"
"Drink. ”
"Broken out?"
"I'm practicing Tongzigong!"
"Do you think anyone will believe it?
"Believe it or not. Anyway, what I practice is Tongzigong. Never get close to women. ”
"Why are you so frustrated?"
"Recently, I didn't get an order. I'm not reconciled. ”
"What list?"
"Copper motor. “
"You still make copper motors?"
It's a pity that your Tyrannosaurus Rex Industries doesn't have copper motors. Otherwise, I will definitely take this list. ”
"What a big list? Frustrated to such an extent, as for it?"
"Three numbers. ”
"$300 million!"
No wonder Thunder Tiger is so depressed. The amount of the dare order is really huge.
Thunder Tiger is actually also a broker. It's just that the scale is larger than Hu Sanniang, with more channels and more customers. However, no matter what, only getting an order is the foundation of survival.
In the international market, there are so many brokers, so few orders, and more monks and less meat, it is not easy to grab them.
That is, Lei Laohu has such ruthlessness that he can barely get out of a little status.
This is still thanks to the Tyrannosaurus Rex industry.
However, the orders for motors are really not dominant in China.
The main problem is the price of copper.
The coil of the motor requires a high-performance copper alloy.
Our country is already short of copper. Copper alloys need to be imported. As a result, the domestic copper price is always higher than that of foreign countries. Copper products are not very competitive.
In addition, the domestic motor manufacturing technology does not occupy an advantage in the world.
There is no advantage in price, there is no advantage in quality, and it is not easy to get an order.
"How much power?"
"50,500,5000 kilowatts. ”
"It's quite powerful!"
"Yes, the domestic quotations are very high! The quality is also average. Foreigners are demanding. ”
"Who did the final order go to?"
"Mitsubishi. ”
"Oh. ”
Wang Bu'an sat down.
He poured a cup of tea for Lei Laohu.
Poured myself a cup of tea too. Serve it up and taste it slowly.
Electric motors and bearings can be said to be mechanical parts. It is also a very important mechanical component. It is the foundation of power machinery.
The difference is that the electric motor itself can also be regarded as a set of machinery, which is a consumer product.
In the field of electric motors, Mitsubishi is indeed the leader.
In second place, Yaskawa is located. It is also a company from Dongying.
The third place is Wolong.
Fourth place goes to Panasonic.
Fifth place goes to ABB.
Sixth place goes to Siemens.
The seventh place is Dayang Electric.
The eighth place is Jiang Te.
The ninth place is Dechang.
In tenth place is Delta from Treasure Island.
The technology for manufacturing electric motors is simple and simple, and it is a few major components such as stators, rotors, coils, and bearings.
Any worker, with a few pieces of iron and a few coils, can make it.
But to say that it is complicated is also complicated. How to make the best of these few simple parts. It is a matter of hard work.
Fortunately, we are not lagging behind, the third, seventh, eighth, and ninth are all mainland brands.
The problem is, Mitsubishi Electric's advantage is really big.
High-level electric motors are almost all Mitsubishi's world. Not one of them.
The brand premiums of Yaskawa, Panasonic, Siemens, etc. are also very amazing. Most of the profits in the electric motor market have been robbed by them.
For example, among the most common air conditioners, high-quality air conditioners use Mitsubishi Electric.
In particular, Mitsubishi Electric occupies a large proportion of DC inverter air conditioners.
"Boss Wang, why don't you also build an electric motor. "Thunder Tiger is whimsical.
"However, I am not even satisfied with the production capacity of bearings now. Wang Buan frowned and said, "Go to the motor again, there is no manpower and equipment!"
"There will definitely be. Even if there isn't one at the moment, there will be one in the future. Lei Laohu tried his best to instigate it.
"You seem to be very eager?" Wang Buan asked meaningfully.
"Eager! Of course eager!"
"Why?"
"Hundreds of billions of dollars in market share, aren't you ready to get a piece of the pie?"
"Huh. ”
"Among them, the automotive electric motor market alone is more than 40 billion US dollars. Aren't you impressed at all?"
"Huh. ”
Wang Buan was actually really unimpressed.
In this electric motor market, the cake is indeed very large. But the competition is fierce.
Profits, not so easy to earn.
He was reluctant to intervene if it wasn't necessary.
However, what is so good is that this motor is exactly in the roadmap he designed!
For construction machinery, hydraulics, bearings, motors, and power are indispensable components. Failure of any system may lead to final defeat.
Three years later, he will come up with the most powerful shield machine to gag other people's mouths.
Is he comfortable letting someone else produce parts?
Of course I don't worry!
The key components must be produced in-house.
This includes various types of motors. There may be many types of motors used on a shield machine.
Different drill bits, different motors.
Different hydraulic systems also need to be matched with different motors.
There are also systems such as pumping, sludge dredging, conveying, grouting, grouting, curing, guiding, wall building, etc., which also need electric motors.
If it's a little more long-term......
Automotive Electric Motor ......
Ship electric motors......
Submarine electric motor ......
One of the most popular words these days is all-electric propulsion.
It is to convert all energy into electricity. Then take the approach of electric drive. It can save energy, reduce noise, strengthen the mechanical structure, etc.
What are the benefits of all-electric propulsion?
The first benefit is that it is conducive to the design of the hull structure.
Conventional power propulsion must rely on propeller shafts. This propeller shaft traverses the main body of the ship, which will bring many drawbacks.
The first is that it is not well sealed.
The second is that space will be wasted.
Again, the efficiency of the propeller shaft is not high. Length is limited.
Again, it's noise that's not easy to solve.
If this propeller shaft is eliminated, then the design of the hull will be much freer.
The diesel engine can be placed on a liquid floating raft, which greatly reduces vibration and noise. The cables are soft and easy to orchestrate without affecting the watertight compartment. The rotational speed of the electric motor is very easy to adjust. Even if you want to reverse the operation, it's a very simple thing. In this way, there is no need for the transmission to exist. It saves space again.
For warships, the benefits are irresistible.
With the current trend development, warships of various countries are also making great strides towards all-electric propulsion.
It is estimated that in the near future, the tank will also adopt all-electric propulsion.
The second benefit is that it can be used more efficiently. It is conducive to the centralized distribution of energy.
Or use ships as an example. If you go at full speed, you can concentrate all the power and supply all the propellers to ensure the speed.
If you want to move forward slowly, you only need to turn on a diesel engine with the smallest power to generate electricity.
In this way, there is much more freedom in the control of power and fuel.
Through scientific calculations, you can greatly save fuel and increase the total range.
The third benefit is to shorten the construction period.
Individual parts can be produced in advance and then assembled together.
Soft connections are also used for each section. There is no influence of the transmission spindle. Welding and splicing with each other is naturally much easier.
From this point of view, the quality of the motor is related to the fundamental quality of the machinery.
It represents the development direction of power machinery in the future!
It seems that I must be taken seriously.
