Chapter 16 Wirewound Potentiometers
Li Zhenbang was in a heavy mood, and said in a low voice: "The problem is quite serious, I have asked Mr. Huang to study the most serious capacitor, and now we are discussing the potentiometer with the smallest problem." ”
Speaking of this, Li Zhenbang paused and said: "The potentiometer problem is the smallest, and it is also relative to the capacitance of our factory. ”
After Fu Xin heard this, he frowned and thought, "The factory produces wirewound potentiometers, right?" ”
"Hmm!" Li Zhenbang nodded, and said, "Our factory can only produce this kind of wire wound potentiometer, this kind of wire wound potentiometer, with high precision, good stability, small temperature coefficient, reliable contact and other advantages, and high temperature resistance, strong power load capacity."
However, there are many shortcomings, mainly manifested in the resistance range is not wide enough, the high-frequency performance is poor, the resolution is not high, and the high-resistance wire winding potentiometer is easy to break the wire, the volume is large, and the cost is high.
This kind of potentiometer can be widely used in electronic instruments and meters. Its resistive body is composed of resistance wire wound on the insulator, there are many types of resistance wires, and the material of the resistance wire is selected according to the structure of the potentiometer, the space that holds the resistance wire, the resistance value and the temperature coefficient......"
Fu Xin knew this, Fu Xin did not let Li Boxian continue, but asked: "How is its wear life?" ”
The mechanical life of a potentiometer is also known as wear life, which is often expressed as mechanical durability. Mechanical durability refers to the total number of times the potentiometer moves reliably under the specified test conditions, and is often expressed as "weeks". The mechanical life is related to the type, structure, material and manufacturing process of the potentiometer, which varies considerably.
Li Boxian didn't think much about it, and replied directly: "The wear life of our potentiometers is not good, far lower than the international level, and even the average level of wear life of domestic potentiometers is slightly inferior." I'm talking to the workers right now about how we can improve the manufacturing process of our wirewound potentiometers.
Because I have found after a number of tests, our wire wound potentiometer, whether from the point of view of materials, or from the structure of this potentiometer, is relatively good, this point, I also went to the phone to consult my mentor, but our production process, there are big problems. ”
This Li Boxian is a talent! Fu Xin sighed in his heart, but asked on his lips: "Then how far have you improved the production process now, can you show me?" ”
"Absolutely!" Li Boxian said without hesitation. "I'll go get the drawings."
Without Li Boxian's hands, the workers on the side had already taken the drawings that were put aside, Li Boxian took it, and then pointed to the drawings, regardless of whether Fu Xin understood it or not, and said directly: "Director Fu, look here, if the resistance wire can be pressed and stacked and wound, will the wear life of our potentiometer increase?" ”
Fu Xin glanced at it, recalled some previous knowledge, and said, "Have you considered the thickness of the resistance wire?" ”
Sometimes scientific research is a matter of piercing a layer of window paper, hearing Fu Xin say this, Li Boxian immediately danced with his hands, raised his arms and shouted: "Director Fu, you are really our lucky star, I have discussed with the workers for a long time, has not been able to cut the point, always put the research direction on the length of the resistance wire and the variety of metal materials used, stunned did not take into account the thickness of the resistance wire, I didn't expect you to come, to solve the problem that we have been bothering for a few days." ”
Someone around immediately figured it out and echoed: "Yes, Director Fu, you are really our lucky star!" The finer the resistance wire, the greater the resistance value and resolution can be obtained in a given space. However, the resistance wire is too thin and easy to disconnect during use, which affects the life of the sensor. We haven't been thinking about it this way, we have been using thin resistance wires, so there is still a problem with the service life of the measurement, alas, why didn't I think of this stubble! ”
Fu Xin has seen the design scheme of this potentiometer, it is really good, it is not outdated in the nineties, and now there is no big problem with the production process designed by Li Boxian, he guessed that they must have entered a dead end, in addition to the problem in the selection of resistance wire materials, I didn't expect that I mentioned it, and I hit the crux of the problem. So Fu Xin was also very happy, laughed along, and calmly accepted the compliments of the workers.
After the workers quieted down, Li Boxian immediately issued a military order to Fu Xin, and Zhengse said: "Director Fu, I can assure you that within three days, a complete set of wire winding potentiometer production plans will be designed." If I can't do it, you can punish me! Whether it's a deduction of wages or a punishment, I accept it! ”
Fu Xin patted Li Boxian on the shoulder and said, "Secretary Li, how could I punish you, it's too late for me to be happy!" I didn't expect that as soon as you came, you would bring a new production process to the factory, so that the efficiency of the factory would increase, how could I punish you! ”
Speaking of this, Fu Xin said half-jokingly and half-seriously: "Secretary Li, this can be regarded as your vote!" ”
"Vote?" Li Boxian didn't react for a while, and then Fu Xin smiled at him again, he thought of what this vote meant, and laughed: "Vote for the name, vote for the name is good!" This is my vote, and please pay the factory director to take me in! ”
Fu Xin and the surrounding workers immediately burst into laughter.
After a burst of laughter, Fu Xin Zhengse said: "Workers, comrades, after the successful improvement of the potentiometer production process, I Fu Xin will hold a banquet for everyone to celebrate, and in addition, I will take out a sum of money from the factory's treasury to reward you!" ”
Fu Xin saw that Li Boxian was shaking his head at him, and immediately said loudly: "Secretary Li, you are no exception, you are the hero of the improvement of the potentiometer production process this time, so your bonus will be the highest!" ”
After speaking, Fu Xin found that most of the workers in the workshop looked at this side, simply climbed onto a workbench, stood on it and said loudly: "Workers, I know that you are all paying attention to this side, I will not blame you for delaying the work in hand this time, it is our human nature to love to be lively!"
On this occasion, workers, I declare to you that I will set aside a part of the money from the factory's treasury to set up a 'hard work' bonus, which will be specially used to reward those workers who love to study and are able to develop new technologies! Moreover, I can clearly tell you that this bonus will not be low!
I think you all know, in addition to my Xunyang Electronics Factory director, but also Yicheng Huaxing Electronics Factory, this 'diligent and enterprising' bonus, I have been set up in Huaxing Electronics Factory, there have been several workers to get this 'diligent and enterprising' bonus.
Among them, the highest person who got this bonus is the workshop director of Huaxing Electronics Factory, and several products he designed for Huaxing Electronics Factory have brought great benefits to Huaxing Electronics Factory, so he has now accumulated a bonus of 36,000 yuan! ”
"Thirty-six thousand dollars...... I thought a few hundred yuan would be a big deal, but I didn't expect it to be 36,000 yuan, doesn't that mean that Director Lu is also a 10,000 yuan household? Someone exclaimed.
"Thirty-six thousand dollars...... So much, it seems that I will work hard in the future, and I am also very satisfied if I don't want to get 36,000 yuan, but 3,600 yuan. "Someone was moved.
"Thirty-six thousand dollars, ......!"
……
"Thirty-six thousand dollars...... It's a lot, it can't be fake, the officials are not good people, they must have joined forces to deceive us! Someone said with bad intentions.
Fu Xin waved his arm, signaled everyone to be quiet, and then said: "I heard many of you talking about 10,000 yuan households, I can tell you clearly, 10,000 households, as long as you are willing to be diligent and enterprising, 10,000 yuan households are not dreams, Huaxing Electronics Factory, just take the bonus to become 10,000 yuan households, there are already two people, so don't think that it is difficult to become a 10,000 yuan household, as long as you are willing to be diligent and enterprising, maybe, the next 10,000 yuan household is you!" I'm done with my words, so let's work in peace! ”
After speaking, Fu Xin jumped off the workbench.
As soon as Fu Xin stood firm, the person standing next to him immediately asked eagerly in order to come up: "Director Fu, are you telling the truth?" ”
"Director Fu, how much bonus can we get after we improve this potentiometer?"
……
"Director Fu, who is there another 10,000 yuan household?" Everyone asked.
Fu Xinyou waved his hand and frowned to signal everyone to be quiet.
When the scene quieted down, Fu Xin said: "Don't worry, this matter is definitely true!" As for how much bonus you can get, please don't worry, I will distribute it according to the degree of your contribution, as much as you can get hundreds, and as little as dozens of dollars! Don't worry, this will be settled for everyone when the salary is settled next month! Let's go work with peace of mind, Secretary Li, can you come with me? ”
After listening to what Fu Xin said, everyone was relieved, and they all went to work happily.
Walking out of the workshop, Li Boxian, who followed behind, asked half-jokingly and half-seriously: "Director Fu, I also want to know how much bonus I can get?" ”
Fu Xin smiled and replied, "Secretary Li, you are also short of money, don't worry, your bonus will not be less than one thousand!" ”
Li Boxian was not shy, and said calmly: "Who doesn't love money, the key is that a gentleman loves money and takes it in the right way!" If you want money, you have to get it from the right way! ”
Fu Xin knew that Li Boxian was showing loyalty, nodded and did not comment on this topic, but said to Li Boxian: "Secretary Li, I have a suggestion to talk to you, do you think it is appropriate now." ”
Li Boxian nodded with a smile, spread his hands and said, "Director Fu, I came out with you, it's not suitable, it's suitable, you can say it!" (To be continued.) )
