Summary of automobile repair work, model essay daquan

Introduction: Summary is a review, analysis and objective evaluation of the learning situation in a certain period in the past. The following is a comprehensive model essay on auto repair work that I have carefully arranged for you. Welcome to read!

Summary of auto repair work: My auto repair knowledge and technology are mainly summarized from practice. Of course, I also got a junior college diploma in auto repair through RTVU and adult correspondence, and recently got the qualification certificate of senior auto repair technician. I used to work in a garage, but now I work in a training center of a private vocational and technical college. My main task is to take students to practice classes, and at the same time, I also undertake the task of teaching students courses such as automobile fault diagnosis and detection technology. No matter where I work, I know that I must apply what I have learned to practice in order to continuously improve my professional skills. Sometimes, in order to find out the ins and outs of an accessory, we compare technical data and study it all night. If you don't understand, you will never leave. What I can't finish in the workshop, I'll take it home to get it. Over time, my home has become my "research institute", and my car repair technology has also been recognized by customers.

Once, I met a Passat 2.0 car and was forced to downshift. I went to several repair shops and didn't fix it. I must come to our factory to repair it. As soon as the car is repaired, I will take the instrument and test drive with the owner. During driving, it is found that when the speed reaches 100 yards, the fourth gear will automatically shift to the third gear, and the engine noise is serious. The owner said that the problem had appeared three months ago. I found a number of repair shops, but I couldn't find the problem. It was repaired three times in the second repair station, and the repair shop suggested changing the gearbox. The owner thinks the cost is too high, so he comes to me for maintenance and then makes a decision. I judge that the failure of "insufficient engine power causes forced downshift" is most likely caused by three-way catalytic blockage. The owner said that it was checked by short circuit method during World War II, and no problems were found. After the test run, I checked it again in detail and determined that it was a three-way catalytic blockage. The shopkeeper is dubious. I promise the owner that if this problem is not solved, our factory will not charge any fees. After removing the three-way catalytic device, it was found that the blocking area had reached more than 85%. After the replacement, the fault was successfully eliminated, which not only solved the troubles of the owner, but also saved a lot of money.

I love my job and meet the needs of users. This is my work belief. Whenever and wherever users call, I am on call. The so-called traditional diagnosis of automobile maintenance work is a method of manual diagnosis of vehicle faults without any testing instruments and equipment. The most commonly used direct diagnosis method in automobile maintenance is "seeing, smelling, listening, asking and trying". At present, the number of luxury cars in China is increasing greatly. However, some maintenance instruments and testing equipment in many repair shops are not in place, which brings great difficulties to vehicle fault diagnosis and even leads to misjudgment. Therefore, it is necessary to rely on the rich experience of maintenance personnel for direct diagnosis. Let's talk about "Q" first. Asking is very important, but it doesn't mean that you can get the correct basis completely by asking. Because the driver's qualification, experience and mastery of the vehicle and performance are at different levels, it is necessary to look for key and important phenomena and ask the driver's answer, which requires the maintenance personnel to have a thorough understanding of the structure and performance of the vehicle and accumulate rich theoretical knowledge and practical experience before they can "ask" a famous story. Secondly, let's talk about "smell". By smelling the oil, we can know the quality of the oil and the basic working condition of the system. By smelling the engine exhaust system, we can feel the working condition of the engine, thus providing guidance for fault judgment. Finally, talk about "test". Commissioning should be the basic skill of maintenance personnel. You can learn a lot of knowledge that is not available in books through trial operation. For example, after the automatic gear is repaired, it will run normally when it is empty, and when it is loaded, it is likely that the vehicle will not be able to drive, turn off at high speed, shift gears, and shake the direction when braking. If there is no personal feeling, it will cast a veil over the judgment of fault, leading to hesitation and uncertainty in judging fault. Therefore, the trial operation can inspire our maintenance work and speed up the accurate judgment and elimination of faults.

Summary of auto repair work: I love my job, be strict with myself, abide by all the rules and regulations of the factory, be strict with myself, keep my job in the right position, and always maintain a "modest, cautious, self-disciplined and positive" work attitude. With the care and guidance of my leaders and the help of my colleagues, I always study hard, make positive progress, strive to improve myself, always work diligently, conscientiously complete tasks and perform post responsibilities. . Constantly strengthen study and work skills!

While doing a good job, interpersonal relationships with other colleagues are also very important. Because a person's ability is limited, all success depends on the collective wisdom. Therefore, uniting colleagues is the premise of successfully completing the tasks assigned by the leaders. This is not only a job, but also a normal life. Therefore, solidarity with other colleagues is not only a personal matter, but also an obligation of work! I have a good relationship with my colleagues and often help each other, because I am a fitter in the garage, and some work must be done with my colleagues, such as the maintenance of X's fuel tank and car door. Work, cooperate with each other.

Regarding the gains and losses in the past, I will learn from the favorable factors, strengthen my working ability, and exclude the unfavorable factors from my future work. A year's work has made me make some achievements on the road of continuous progress for remanufacturing. I believe that through my efforts, the cooperation of my colleagues and the guidance of my leaders, I will become an excellent employee, give full play to my ability, and thank my leaders for giving me a suitable job position, so that I can make due contributions to society.

Over the past year, I have earnestly completed the essential work, and I believe I will continue to work hard in the future. Although my work this year is still unsatisfactory, I believe that as long as I stay in my post for one day, I will try my best to put all my energy and ability into my work, and I believe I can do it well!

Summary of Auto Repair Work Fan Wensan: In 20XX, I graduated from College of Mechanical Engineering, Chongqing University of Science and Technology, majoring in internal combustion engine manufacturing and maintenance. I just graduated from college and came to work in the company. During my work, I gradually mastered the basic requirements of vehicle maintenance through serious internship and diligent practice. Under the careful care and guidance of leaders and colleagues, I have made some progress in all aspects through my unremitting efforts. Now I will report my work. Please point out the shortcomings!

First, there are roads in Shushan, and the sea of skills is boundless.

When I arrived at the maintenance and manufacturing center, I knew that as a skilled worker, if I didn't understand the drawings, the principle of equipment and the structure of vehicles, I would not only be embarrassed, but also be a qualified worker. I overcome the unfavorable factors such as lack of practical experience, and strive to "refuel" myself with a "bull's strength" of not stopping until I reach my goal. I sorted out some useful technical books, deeply studied technical theories such as vehicle structure and mechanical foundation, and applied what I learned to production practice to continuously improve my professional skills. Sometimes, in order to find out the ins and outs of an accessory, I will study the technical data all night, and I will never give up until I understand it; Sometimes, what I can't finish in the workshop, I take it back to the dormitory for research. Over time, my dormitory became my "research institute". Many things happen. After studying hard, I have made rapid progress, but I am not complacent at all. I know that although I am a college student, many masters in the maintenance and manufacturing center have rich experience and are examples for me to learn. On the road of learning professional technology, there is no room for any falsehood and slack. I will make unremitting efforts to make new contributions to the enterprise.

Second, be brave in tackling difficulties and solving problems.

With my intelligence and professional skills, I solved a series of problems for the maintenance and manufacturing center together with the masters, and overcame one difficulty after another. In April this year, the maintenance and manufacturing center informed me that there was a car with load reverse gear, which was repaired several times but failed to be repaired. As soon as the car was repaired, my master and I immediately took the tools to test drive with the driver. When driving, we found that the reverse gear automatically jumped in the desert section. The driver said: the problem appeared three months ago, but I couldn't find it. After discussing with the master, I judged that the driver said that it had been replaced and no problems were found. After the test run, my master and I checked it again in detail, and we still determined that it was an inverted slide. After disassembling the gearbox, it was found that the toothed hoop used in reverse gear was abnormal. Although the size is the same, the shape of the teeth is different, which is the direct cause of gear shifting. After the replacement, the fault was successfully eliminated, which not only relieved the driver's troubles, but also saved a lot of money for the company.

Third, love and dedication, warm service.

"Standing to be a man, kneeling to serve" is the service concept of transportation companies. At work, I have seen many vehicles with brake failure while driving. I have made an in-depth analysis of this kind of problems and come to the conclusion that there are several reasons for the failure of braking when driving: insufficient compressed air pressure generated by the braking system. Because the air cylinder of the vehicle cannot store enough compressed air, the air source of the brake valve is insufficient; The air leakage of the brake valve pipeline and the blockage of the air path will cause insufficient compressed air pressure generated by the brake system during braking; The gap between the brake drum and the brake shoe is not suitable; The contact area of the brake shoe is too small. According to the above reasons, around the problem of brake failure, I have consulted and studied relevant maintenance materials many times, humbly consulted experienced teachers, and examined and analyzed the possible reasons one by one. For the part that may fail, I will adopt the method of "from shallow to deep, from easy to difficult". I'll check the air storage tank first to see if the air pressure meets the standard. Start the engine, check the pressure gauge response of the brake system, and find it difficult to inflate. Expansion >; It takes 3 minutes to charge to 0.3MPa, which may be due to the failure of the air compressor or the leakage of the sealed air pressure pipeline, which makes it difficult to increase the air pressure. I checked the air pressure when the engine was running at a medium speed and found that it rose slowly. After the flameout, I checked the air pressure and found that the air pressure dropped rapidly, exceeding the standard value. Check whether the tightness of the air compressor drive belt meets the requirements, and then remove the air compressor. It is found that most of the pump cover has carbon deposits, and the air inlet is also blocked by carbon deposits. After removing the carbon deposit, put it back on the pump cover and accessories. Found that the effect is better than before. The air compressor has obvious pumping sound and good working effect. Then connect the output throat of the air compressor to continue to start the engine, gradually relax the test air volume of the pipelines in front of the main valve, and then completely remove the carbon deposits on the blocked pipelines.

Through the above operation, the air pressure can reach above 490 kPa shortly after the engine is started. I judged the fault according to the pressure drop after stepping on the brake pedal, and found that the pressure drop was normal. However, after the pedal is released, the exhaust volume of the exhaust valve is insufficient. I immediately disassembled and inspected the master brake valve, and found that there was an obvious groove on the valve glue of the intake valve. The valve glue of the exhaust valve is not properly closed. After modification, I adjusted the exhaust valve, and then I adjusted the gap between the brake shoe and the brake drum of the rear wheel to the best position, so that there would be no delay. And check whether the extension stroke of the push rod of the front and rear four-wheel brake air chambers reaches the specified value. The stroke of the front wheel push rod should be 15 ~ 35mm, and the stroke of the rear wheel push rod should be 20 ~ 40mm. Unexpectedly, in the process of inspection and adjustment, it was found that the push rod of the left and right wheel brake air chamber was laborious, slow and inflexible. When the air inlet pipe of the brake air chamber is disassembled, air is exhausted, which proves that the air pipe joint is not blocked and the valve glue is not leaked, which indicates that the reason for this phenomenon may be that the lubrication is not serious enough during the first-level maintenance, or that the camshaft and bushing are rusted due to long-term loss of grease, resulting in difficult thrust and short push rod stroke.

Therefore, jack up the wheel, then turn the wheel and try to press the brake pedal. Sure enough, the wheels stopped slowly instead of immediately, which proved that the camshaft had lost its function. Immediately remove the left and right wheels and the brake cam push rod for rust removal and lubrication adjustment, clean the entire brake drum to 1200, and check the tension of the brake shoe return spring. Intuitively, the spring has been corroded a lot. Comparing the old and new springs, it is confirmed that there are differences in elasticity and thickness, so a new one is replaced. After replacing it with a new one, the fault was eliminated. After the test run, the original brake failure of the car was eliminated.

Fourth, strengthen self-cultivation and move closer to the party.

As the saying goes, "It's never too old to learn". I have been strict with myself in all aspects and strive to improve myself in order to adapt to the situation of social development more quickly. Actively study political theory through newspapers, magazines and books; By reading a lot of books on moral cultivation, we can dissect ourselves, analyze ourselves, face ourselves squarely and improve our quality. Abide by the law and study legal knowledge seriously; Love my job, actively study professional knowledge, have a correct working attitude and be serious and responsible. At work, I deeply felt the strength and mission of the staff. The kind and simple staff are unknown, conscientious and studious in extremely difficult environment, and their fearless spirit in the face of difficulties deeply touched me. Although I have never suffered anything since I was a child, I can't easily miss this great opportunity to make up lessons. By strengthening study, studying Theory of Three Represents theory and Scientific Outlook on Development seriously, and combining with the excellent party member around me, I will constantly improve my theoretical level and ideological level.
