"Otherwise, I'll try." Zhou Jianhua, who had not spoken, suddenly interjected.

"Who? You? Chen Guodong and Fang Guisheng didn't react at first, and when they heard someone volunteering, they were overjoyed, and when they turned their heads and saw that the person who spoke turned out to be Zhou Jianhua, both of them were deflated.

"You know what?! Adults are discussing business, what are you kidding around?! Stay and go! ”

Before Chen Guodong could speak, his cousin Lin Yongliang had already rushed over, he scraped the back of Zhou Jianhua's head with his hand, glared and reprimanded loudly.

This kid can't be stupid after being hit by a flatbed truck, people and electricians can't fix things, what are you talking nonsense about a junior high school student. Director Chen is annoyed now, you are talking nonsense like this, and you are not afraid that the director will be angry?

"Uncle, I'm not talking nonsense, I really know how to fix a winch." Zhou Jianhua said depressedly.

For Zhou Jianhua before, the winch is of course a complex and incomparably complex thing, but for Zheng Zhi, who was the chief engineer of the national defense key model project in his previous life, this is just a small toy.

Thinking that he changed his name and surname from the chief engineer of the national defense key model project with a double doctorate degree in mechanical and electronic engineering and electromagnetic field and microwave technology, and suddenly changed his name and surname to a student who had not graduated from junior high school, Zhou Jianhua also had to sigh that the world is unpredictable, until now he is still very confused, I don't know whether this crossing is a good thing or a bad thing, although he is 20 years younger, but the great changes in the environment will bring him what kind of new life will it bring......

"Will you fix a winch? Do you know what the structure of the winch is? Chen Guodong said disdainfully, fortunately, he saw that Zhou Jianhua had just been injured, and he didn't want to deal with him, otherwise he wouldn't even be interested in talking.

"Actually, the circuit of the winch is very simple, I'll draw it for you!" Zhou Jianhua pretended to be honest, he picked up a coal block and drew a sketch on the ground:

"You see, our winch is an electric speed-regulating winch, which is powered by an electric motor, driven by an elastic coupling, a closed gear reducer, and a tooth-embedded coupling, and uses electromagnetic braking...... This is its circuit schematic, which is mainly composed of motor power supply lines, electromagnetic brake power supply lines, direction and speed control circuits. Among them, the most complex and critical is the direction and speed control circuit part, which determines the respective output torque of the motor and the electromagnetic brake, and also determines the linkage state of the motor and the electromagnetic brake......"

Zhou Jianhua drew as he spoke, and in less than two minutes, he drew a large schematic diagram on the ground. The onlookers were stupid, although they didn't know whether Zhou Jianhua was right, but he was able to draw such a large picture, and if he was replaced by someone else, he didn't know where to start painting Lu Dao.

Chen Guodong was also shocked by Zhou Jianhua, he was stunned for a long time before he turned his head to look at Fang Guisheng and asked, "Master Fang, what do you think?" ”

Fang Guisheng had been intently observing Zhou Jianhua's sketches and explanations just now, but Zhou Jianhua was right about everything he knew before, he didn't know much about it before, and he seemed to be inspired by Zhou Jianhua's explanation, at least he didn't find anything wrong in Zhou Jianhua's entire explanation process. Hearing Chen Guodong ask him, he replied, "Hmm! That sounds like a pretty good thing. ”

Chen Guodong stared at Zhou Jianhua again: "Are you really sure that you can fix it?" ”

"Seventy or eighty percent of it." Zhou Jianhua left a little discount.

"Prepare tools for him!" Chen Guodong said, and then added: "If it's repaired, I'll get the money, and if it's not repaired, go home quickly!" ”

After Chen Guodong finished speaking, he left with his hands behind his back, and everyone couldn't help but be gloomy when they looked at his background. Chen Guodong's words are a pun, this kid is so crazy, if he has real skills, it's just that, if he can't fix it well and smashes the pot, it's a big fool, as a dignified commune director and mine chief, if he is fooled by a little baby in front of so many people, how faceless it is! Then you still need to mess around in this mine, why don't you go home and don't come again!

At this time, Lin Yongliang was staring fiercely at his nephew and sulking, Zhou Jianhua's father died of illness a few years ago, and the Zhou family's economy was very poor. In order to help his cousin's family, Lin Yongliang cheekily found Director Chen Guodong, and finally won Zhou Jianhua an opportunity to enter the Tuanlin Coal Mine to make money during the winter vacation. Now that Zhou Jianhua is so arrogant in front of Chen Guodong, how can he stay in the mine in the future?

Zhou Jianhua pretended not to see his uncle getting angry, walked to the electrical control cabinet of the winch, bent down and skillfully twisted the door of the electrical cabinet, and began to check the wiring of the electrical control system of the winch. The workers who had already left work just now were not in a hurry to go home at this time, and they all gathered around curiously, whispering on the side:

"Andy really knows how to fix this thing?"

"It can't be that I heard that there are 30 yuan, and I am a money fan, right?"

"It's hard to say, you see he's quite skillful......"

A few minutes later, Fang Guisheng took electrician Zhuang Minghui to bring electric pens, multimeters, electric soldering irons and other tools, and put them next to Zhou Jianhua, Zhou Jianhua had already roughly understood the line direction of the electrical cabinet of the winch and the layout of various functional components.

After getting the multimeter, Zhou Jianhua immediately adjusted the file and measured it. First of all, in the case of the equipment is electrified, the parameter data of several components began to be measured, and then the winch was started to let it run, and a few data were measured, and the power switch and power-off switch of the equipment were turned off after the most difficult time, and many components were measured in the case of complete power-off, and the multimeter needle in the hand continued to jump and touch quickly on various electronic components and devices, and constantly changed the test gear of the multimeter during the period, and from time to time used a pen to draw a few circuit diagrams on the paper and record some test data.

The people around him watched Zhou Jianhua's operation silently, although they didn't know what he was doing, but he felt that his hands were like playing the piano, smart and full of mysterious rhythm, and he couldn't help but have a solemn feeling, is this the legendary unclear sense?

Zhou Jianhua's measurement technique was extremely fast, and the two people in the mechanic class had been close behind Zhou Jianhua, watching intently, but they were also dizzying, and they didn't understand what parameters Zhou Jianhua was measuring at all.

In just five minutes, Zhou Jianhua stopped measuring, and began to carefully scrutinize, calculate, and think about the relationship between the various parameters with the recorded line and parameter sketches, and there were words in his mouth: "...... Impedance 12.3 ohms, inductive reactance 78.8 ohms, capacitance 60 picofarn, critical voltage 0.7 volts, magnetic flux equal to ......"

Fang Guisheng is a fitter, so he naturally can't understand these concepts. Zhuang Minghui himself is an electrician, and he can understand several parameter concepts, but he cannot understand the relationship between such complex circuit parameters.

After a few minutes of calculation, Zhou Jianhua stopped his pen, got up again and came to the electrical cabinet, measured a component on the circuit board with a meter, and then said, "That's it!" This diode broke down! ”

After that, he turned his head to Zhuang Minghui and said, "Master Zhuang, please remove this diode and find a similar diode to replace it!" ”

Zhuang Minghui seemed to be possessed by a ghost, and he didn't even think about whether it was inappropriate for a young man to command himself like this. He ran back to the studio in a hurry, and sure enough, he found a spare diode, and replaced it quickly according to Zhou Jianhua's instructions.

Zhou Jianhua watched from the side, nodded and praised: "Well, Master Zhuang's craftsmanship is really good, and the solder joints are very beautiful." Well, now it's time for a test run! ”

After receiving Zhou Jianhua's praise, Zhuang Minghui actually felt a sense of pride. Zhou Jianhua looked at the smile on the other party's face, and couldn't help but pat his head: Wrong, wrong, how did he bring the habit of being a leader in the future...... Not to mention, we really have a bit of a king's spirit.

Hearing Zhou Jianhua say that it was time to test the machine, the members who were watching nearby were in a commotion, and they were all whispering:

"Will it work......

"It's going to be tested right now! Try it and you'll know it! ”

"I think it's okay to look at him......"

At this time, Chen Guodong also walked over from a distance. Just now, he resolutely walked away without looking back and left a cruel sentence, really because he was worried that if Zhou Jianhua belonged to the typical kind of young man who had no hair on his mouth and did not do things firmly, he would be laughing and generous. From his heart, he really hopes that Zhou Jianhua can really do what he says, first, he can solve his urgent needs, and second, in the future, he will have a technical power that he can control.

However, if Zhou Jianhua is really such a good person, it is really a character who defends the sky, it is really unbelievable!

Until this time, Chen Guodong was still very worried in his heart.

"Turn on the power-off switch! - Turn on the power switch - down to start! Zhuang Minghui followed the instructions issued by Zhou Jianhua and began to control the winch for testing.

With a low roar of the motor, the flatbed truck was pulled to accelerate, reaching a normal speed after more than ten seconds.

"Downward Parking Brake!"

Zhuang Minghui pressed the stop button, and the flatbed began to slow down and slide, braking within 10 seconds, fully meeting the qualified requirements.

"Uplink starts!"

"Upward Parking Brake!

"Smooth upward braking, no rolling!" The people in the equipment work area soon came with news from the roadway, which means that Zhou Jianhua's commissioning was successful!

Almost everyone present cheered:

"Andy, good job!"

"Zhou Jianhua, you are too godly!"

……

With such a person to help maintain the equipment, the workers will no longer have to risk the risk of slipping in the future, and they will be down-to-earth when they work, of course everyone is happy, and Zhou Jianhua has become everyone's protector.
