怎样学习家电维修技术（How to study appliance maintenance technology）

1、怎样学习家电维修技术（How to study appliance maintenance technology）How to study appliance maintenance technologyFirst of all, to have a clear understanding of the home appliance repair appliance repair appliance repair technology technology: 1, technology learning appliance repair technology should have certa

2、in cultural foundation, especially in junior high school physics knowledge about electricity, such as current and voltage to have a general understanding; 2, whether on the door interested in technology, because learning is not playing games, and electronic knowledge relative to other technology is

3、more abstract, if you do not love it, learning together will feel dull as ditch water but if interested, you will feel its infinite, learn the more effort; 3, learning how to develop their own home appliance technology: at present, learning the art of the way there are several a, their own business,

4、 after a lot of hard work this mastery of the technology to a certain extent, you can shop business, in Both urban and rural areas can. Because peoples living standard continues to improve, all kinds of household appliances are becoming more and more popular, the microwave electromagnetic oven, and

5、other electrical appliances have entered thousands of households, a home appliance repair shop is an iron outlet; B, a brand to do customer service maintenance, our previous graduates of Haier, Konka, SKYWORTH and other major brand work of tens of thousands of people at present, including a departme

6、nt manager, technical director of a class of talents; C, to enterprises, hotels, shopping malls and other do maintenance work, each large enterprises will have hundreds of such household appliances, such as air conditioning, TV and so need daily maintenance, this kind of work intensity is low and st

7、able income, the development of good is also a great space. Secondly, we should choose a professional school for systematic study. Choosing a school is important in learning a technology. Some schools offer less than dozens of majors, as long as they are citiesOn the field there is a need for such t

8、alents, or to see other schools do good, and their own to open, the result is because the school leaders themselves lack of professional knowledge, delayed the future of countless students. Therefore, the choice of schools must choose schools specializing in this technology, they have a wealth of ex

9、perience, you can in a short period of time to master the focus of this technology. Again, for the study of technological learning appliance repair appliance repair technology, I do not encourage self-study, because this technology learning appliance repair technology system greatly. It needs to mas

10、ter the electronic electrician foundation, solid if self-study, it may take a lot of time and energy, and sometimes a word from the teacher will make your spear seton. Finally, is to go to the system of learning, in learning this technology, we should pay attention to the following points: 1, step b

11、y step, do not expect to eat a fat person. From the understanding of electronic components - Radio - black and white - color TV - disk machine - - and finally to LCD and other high-end products. 2, to integrate theory with practice, dont memorize theory, not just practice, without reference to the t

12、heoretical knowledge, we need to do both, using theory to guide practice, found in practice with theory to solve the problem again, so that your technology by leaps and bounds. 3, we must be good at summing up, each have a knowledge point, to take notes, do not have to learn from scratch in the next

13、. Especially in practice, a problem is found, and after a lot of efforts, it must be summarized and recorded, so that your experience will become more and more rich.The reason of small household electrical appliances fault diagnosis and maintenance method of small household electrical appliances fai

14、lure generally has the following: component damage, poor insulation or short circuit, welding weld or sealing, circuit break, bad connector, moving parts and external causes in a short circuit. Commonly used methods of maintenance are the following. 3.1, principle analysis method: according to the b

15、asic structure of small household electrical appliances and working principle, analysis of the fault phenomenon and the link between parts, to determine the scope of the fault or damaged components. 3.2, measurement method is used testing equipment (mainly multimeter), measuring the working voltage

16、of the circuit or component, the working current and static circuits or components between the two resistors and a marked value control, to determine whether the normal working circuit and the components are damaged. 3.3, visual inspection method: that is, we use our five senses to check (including

17、to see, listen, smell, touch) the damaged small household appliances, to determine the scope and causes of failure. 3.4, circuit division method: that is, and the fault has been implicated in the circuit segmentation. By checking, affirm a part, deny a part, reduce the range that the fault may produ

18、ce step by step, and judge the scope of the fault effectively. 3.5, short circuit bypass method: in order to enable the 1.3 circuit is not affected, according to the needs of the other components of short circuit or bypassed. 3.6. Equivalent substitution method: a device, system, or unit that replac

19、es a faulty or suspected fault in a circuit with a normally functioning component, system, or unit to quickly determine the scope of the fault.3.7, knock vibration method: This is to check poor contact a common method. Small household electrical appliances, pins and solder joints are many, due to po

20、or contact, the machine is good and bad, inspection is difficult. In this case, you can gently tap each part, find out the most sensitive parts of the percussion, this part may be poor contact parts. The maintenance time can be greatly shortened by using this method. 3.8, joint treatment: in determi

21、ning the bad contact or solder joints weld parts, weld joints of suspected components, using lead tweezers or nose pliers appropriate light dial elements, such as, it will lead desoldering joints weld drawn, electric soldering iron welding a suspicious point,. Remove weld, sealing off. In the mainte

22、nance of specific small household electrical appliances, the principle analysis method can be used and combined with several other maintenance methods to detect the fault area until the components, and to take appropriate methods for maintenance in light of specific conditions. Here are three common

23、ly used small household electrical appliances, for example, for the maintenance of small household electrical appliances for further study.Household appliances, household appliances, household appliances, appliances used in homes and similar places. Also known as civil electrical appliances, househo

24、ld appliances. The United States is the birthplace of home appliances. In 1879, the American T.A. Edison invented the incandescent lamp, which created the era of household electrical appliances. In the early twentieth Century, the American E. Richardson invented the electric iron on the market, prom

25、pting other household appliances to come out one after another. Electric washing machine, vacuum cleaner, compressor type household refrigerators, air conditioning, electric cooker, automatic washing machine came into being. In 1880s, the discovery of Edison effect and the verification of the existe

34、ing collocation, can we communicate after the job, and the future work of interpersonal communication, win the goodwill of others and identity, as we are out of college students can quickly integrate into the society and lay a solid foundation. Through a semester of clothing collocation study, so th

35、at I have a certain understanding of clothing collocation and understanding. The concept of clothing, clothing, makeup, hair collocation including clothes. What we usually say is a one-piece garment. Each garment is called a single product. The concept of clothing collocation should include the foll

36、owing: 1, clothing with physiological aspects (i.e., their warm aspect) and psychological (i.e. confidence) and other two aspects. 2, clothing collocation refers to the overall design of personal image. 3, clothing collocation should contain several elements: style, accessories (clothing), personal

37、conditions, the environment, time. Two, color display clothing collocation of color, primary colors are: red, yellow, blue. The other is the color and light colors complement each other and intermodulation and primary colors. Three primary colors of light: red, yellow, and green. The color display m

38、ainly includes: 1, take the color brightness as the subject 1) and the brilliance color matching. Refers to a bright color based color matching: such as: whiteAnd bright gray or egg yellow or light pink or light green matching each other, can reflect the wearer lively and lively image. Such a match

39、is often used in summer. 2) mid and bright color matching. The middle lightness refers to the medium lightness of the main colors: such as gray and gray or gray, green or blue or brown, matching each other, it can reflect the wearers subtle, quiet image. This kind of lightness collocation is the mos

40、t common, this kind of collocation can be used all the year round. 3) low brightness color matching. The low brightness color to color deep in these three kinds of color lightness: such as black and dark gray collocation or dark red, dark brown, dark green, blue or dark blue collocation, can convey

41、a dignified, calm image to the people. This kind of collocation is commonly used in winter. 2, color purity as the theme, color matching to color purity as the theme, color matching mainly includes two points, that is, with high purity color matching and low purity color matching. High purity color

42、matching is generally of medium brightness, with strong color sense and strong color matching effect. And low purity color is relatively plain, implicit, quiet and mature temperament. Three, image and color collocation, 1 white complexion: for skin partial white people, such as the collocation slants cold tonal, obviously it is not sick, with light blue
