Summarization is a kind of application writing, which is a rational reflection on the work that has been done. Below I have collected a summary of the work of mechanical design engineers for your reference.
Part I: Mechanical Design Engineer Job SummaryTurning into the company has been more than half a year, when I first came to the heart is always full of fear, but now the heart is full of dust settled sense of belonging. The company's operation and corporate culture has been further recognized, more clear about their own work direction and work objectives. Looking back to 20xx, both the harvest of solid and happy, but also due to the inadequacy of the regret and guilt. I am under the guidance of the leadership, better integrated into this tense and rigorous atmosphere, better completion of the tasks, their own business quality and work ability has improved, more confident in their work. This half a year, I participated in more product design, from which I benefited greatly, not only learned a lot of professional knowledge, a more comprehensive understanding of the power plant ignition technology and grasp, but also cultivated me as a mechanical design engineer should have the basic quality. Specifically summarized as follows:
First, the work achievements in 20xx (in chronological order)
1, the improved design of the air filter
According to the functional characteristics of the old air filter and the actual situation of the site installation and maintenance, to modify the structure of the equipment, in order to achieve a better installation and use of performance.
2. Participate in the design of double-excitation atomizing nozzle
According to the leadership design ideas, combined with the old drawings of Apex, change the unreasonable places, so that the nozzle is more delicate and more powerful.
3, micro-oil grease gun design
Combined with the new design of the double-excitation atomization nozzle, the design of a new dedicated to micro-oil small grease gun technology grease gun.
4, participate in the design of fuel purification regulator
According to the overall design of Manager Guo, disassembled and refined parts drawing design. This is a relatively fine detailing process, the beginning did not fully understand the design intent of Manager Guo, there were some deviations, and finally, after communication and research, to eat through the design ideas, and successfully completed the design task. I feel lucky to have cooperated with Manager Guo in designing the products, he is a dynamic authority figure with high business quality and good character, he is the one who made me have a more comprehensive understanding of the combustion technology in a short period of time. Currently has produced two prototypes.
5, small oil gun design
This project for the Luoyang Shuangyuan Cogeneration Co., Ltd. 3, 4 furnace burner renovation of the design of the product, completely according to the requirements of the Luoyang Shuangyuan Cogeneration Co.
6, high-pressure combustion chamber design
According to the design task under Manager Guo, the design of high-pressure combustion chamber applicable to micro-oil lance was designed with reference to the old drawings of Apex. Designed two sets of programs to choose from.
7, participate in the Luoyang Shuangyuan Cogeneration Co., Ltd. 3, 4 furnace burner design
Luoyang Shuangyuan Cogeneration Co., Ltd. 3, 4 furnace burner is a new product, specially designed for the Luoyang Shuangyuan Cogeneration Co., Ltd. 3, 4 furnace burner renovation and design. In order to Luoyang Shuangyuan Cogeneration Co., Ltd. for this project, we specifically to Luoyang Shuangyuan Cogeneration Co., Ltd. on-site mapping. At first I thought the mapping was a simple job, but when I arrived at the site and started to work, I realized that the work was not as simple as I thought, the work had to be carried out inside the boiler, and it was very dirty and hot inside. Under the leadership of Mr. Guo, we carefully measured each burner and took pictures, fearing that we might miss some important parts. After measuring the inside of the boiler, we also mapped and photographed the connecting joints on the outside and obtained a lot of information. This surveying and mapping work, I am very touched, especially the kind of meticulous, rigorous and serious attitude of Manager Guo's work, so that I benefited a lot. This product I participated in the design under the guidance of Manager Guo, the current drawings have been designed, waiting for the review of drawings after the figure.
8, participated in the design and production of publicity color pages
As our combustion technology is not a newly established department, we lack of publicity materials. In order to better achieve the effect of publicity to the outside world, Guo manager asked to do publicity color pages. To this end, I produced a large number of various perspectives of the product images for the publicity color page design and production options. Due to the limitations of the ability, the layout of the color page was transferred to Wang Gong is responsible for.
After a few more checkups, the final draft was finalized after the leadership's review. The color page printed out the effect is very good.
9, Xu combustion burner design
According to the photo shape and mapping data, the design of the burner (design in progress).
Second, 20xx learning achievements
20xx, I combined with the development of the machinery industry, the company and my personal situation, focusing on strengthening the learning of the catia software assembly module, mastered the mechanical design of the current latest tools to broaden the design ideas, improve the design ability. In order to enhance the level of design, I self-study welding process. The purpose of learning is to apply, in the future work, I will seriously consider the full application of the new technology learned, so that the design of a higher level.
Third, the improvement of work style in 20xx
"Three years to grind a sword, now put to show the gentleman", after three years of work, I have completed a complete transformation from school to society, has abandoned those unrealistic ideas. I have abandoned those unrealistic ideas and devoted myself to my work. As I became more and more comfortable with my work, I began to consider how to make new achievements in my work in order to realize my own value. I have never been positive, never willing to lag behind, I keep telling myself: must do everything well, must go all out. Through - 3 - these years of touching and rolling afraid, I y realize: careful, rigorous is the quality of designers should have, and integration, touching and continuous innovation is the key factor to determine the mediocrity or excellence of the designers. I want to make my design ideas more and more open, I want to enjoy the design, I want to make a difference in the mechanical field. Doing things full steam ahead and rigorous, meticulous work attitude should be my 20xx years of work style of the biggest gains.
Four, do not do enough
Lack of courage to take responsibility independently. Encountered problems, like to ask others to solve, and can not make a decisive decision. Later solved one by one problem, only to find that things are not as complicated as I thought, I lack the courage to take responsibility independently. Also, my social skills need to be strengthened. Maybe it's because of my personality, I don't like to talk, I just like to bury my head in the sand. Now it seems that this is far from enough, I need to face customers, need to communicate with others.
20xx year has left in a hurry, full of hope for the new year is coming to us. Road is long, the road to seek a long road, I will shake the spirit, pioneering and enterprising, for the development of the company and the personal value of the 'realization and make unremitting efforts.

Part II: Mechanical Design Engineer Job SummaryIn the past few years, in the leadership of the strong support, enthusiastic help, colleagues work closely with the spirit of doing things practically and seriously, the principle of work, and better to complete the work and leadership of the tasks assigned to the individual work ability to make some progress. Now the work and study situation is summarized as follows:
1 professional and technical level and business capacity
I comprehensively and systematically study and master the basic theory of metallurgical machinery during the university and professional basic theoretical knowledge. After joining the work, these theoretical knowledge has been broadened and improved. Work attention to learning and mastering new knowledge, new technologies, and apply them in practice. The use of advanced technology and equipment on the production equipment for the transformation, such as in the sintering machine back to the road to prevent the cart "arch" device, the sintering machine slide from the centralized lubrication to intelligent lubrication, etc., have greatly reduced the failure rate of equipment and maintenance personnel labor intensity, and achieved good results.
He has participated in the construction, installation and commissioning of the new 1# blast furnace overhaul project, and participated in the preparation of the second ironmaking "sintering system equipment operation and maintenance procedures", "pelletizing equipment maintenance, repair, management control instructions" and "sintering equipment maintenance, repair, management control instructions". After several years of work accumulation, the level of professional and technical level has been greatly improved.
2 master 60m sintering, 400,000 tons of pelletizing machinery and equipment operating parameters and status, so that the equipment is in a safe, stable and efficient operation. Make the maintenance cost of the equipment to spend more reasonable, the labor intensity of workers to reduce.
2 main work achievements
2, 1 ?1) Responsible for completing the repair, maintenance and transformation of equipment in the process of overhauling the sintering of the second ironmaking in 20xx. The use of overhaul time on the sinter ignition system transformation, igniter burner and prefabricated parts down 100mm, shortening the burner flame to the material layer length, saving gas consumption, and achieve good economic benefits. In the disk feeder 1 #, 2 #, 5 # in the bin mouth side to add a piece of discharge plate, and the original discharge port angle were 32 °, 27 °, 27 °, by changing the angle of the discharge port, to change the location of the falling material purpose. The position of the discharging point is changed after the machine is started, and the iron-containing materials are evenly distributed in the middle of the skirt belt, which reduces the leakage of materials and improves the accuracy of dosing. In the overhaul of the sintering machine, the slideway and rail were replaced together in the overhaul, and the rail was leveled with the height of the sintering machine slideway to find the correct rail height, and finally the sintering machine sealing device was left with a compression gap of 5mm under the self-weight as the standard. During the production, the cart was running well, and the air leakage rate was significantly reduced.2) Responsible for completing the repair, maintenance and renovation of machinery and equipment during the overhaul of 400,000 tons pellet in 20xx. The overhaul mainly replaced the disk body of 1# pelletizing machine, which was completed in quality and quantity within the limited time, and the one-time test run was successful. Pelletizing workshop circulating fan rotor, shell due to the inlet dust exceeds the standard, wear and tear faster use of short life, rotor, shell every 3 months to replace. After research in the fan shell inlaid wear-resistant liner, rotor blades with wear-resistant welding rod surfacing, good dynamic balancing after 6 months on-line use of good results, greatly reducing the maintenance costs and maintenance labor intensity. During the chain grate grate bed gap for uniform adjustment, to prevent the grate gap leakage ball. 3) completed the second iron sintering sieve building bag dust removal and other transformation projects.
2, 2 ? Currently in the ironmaking plant is responsible for the second ironmaking workshop sintering, pelletizing workshop mechanical technology work, responsible for mechanical equipment planning overhaul, repair and routine maintenance, participate in or organize the analysis of related equipment failure, participate in the modification or change of the version of mechanical equipment operation and maintenance procedures and supervise its implementation, preparation and reporting of spare parts, material plans and implementation of spare parts, materials, inventory, accuracy, arrival and use. etc. Ensure stable, accurate and reliable operation of mechanical systems. In order to meet the needs of the production process, but also on the part of the region's equipment transformation, so that it is more perfect, stable and efficient operation.
2, 3 ?
21) 60m sintering machine used in the tail swing frame circulating sintering machine, after many years of operation, it was found that when the trolley along the curved road from the tail back to the roadway, there is the phenomenon of the cart "arching", that is, the rear wheels of the cart uplift, can not be in contact with the lower track of the return roadway, the height of arching is not the same, and the lower trolley falls down in about 1 hour every interval, and the lower trolley is not the same as the lower track. About 1 hour, the lower part of the cart drop appeared smashed rail phenomenon, with the running time longer and longer this phenomenon is more and more serious, this must be solved this production of a major hidden trouble.
2 specific program is: first of all, according to the present 60m sintering machine back to the highest height of the cart arch, to determine the processing dimensions of the curved rail, find the mechanical design manual to confirm the 38 kg / m cross-section width of the heavy rail, to determine the width of the curved rail dimensions; followed by drawing to riveting and welding to process out the blanks, and then to the metal workshop drilling, boring plane and other processes. Bent rail fixed to weld firmly, the height should be greater than the height of the cart arch, so that when the cart passes through the uniform self-leveling. At present, the cart is running well, there has not been a large-scale smash rail phenomenon, at present, this technology has been in the ironworks 1 #, 3 # sintering machine on the promotion of the use.
2) Completion of the sintering main extractor fan on-line detection of vibration device modification, the sintering main extractor fan due to vibration value exceeds the standard and frequent failures and shutdowns, the ability to detect the vibration value exceeds the standard to protect the sintering of stable production, the key to high production. The vibration value will not exceed the standard when the fan is running normally, but when the fan load changes suddenly or the rotor wear appears unbalanced, the fan vibration value will exceed the standard. Now the method of detecting fan vibration is carried out manually, and the on-duty electric clamp regularly measures the vibration of the fan. This detection method has poor real-time performance, a large risk factor in the detection process, and a relatively large data error. After installing the automatic vibration detection and protection instrument, it is put into use with good results.
3) Complete the optimization of dry zipper transmission mode, reduce the failure rate of the project. Dry pull chain head and tail wheel in the sintering production line are tooth type transmission. When the chain runs for a period of time, the chain link pin hole wear is stretched to cause the dry zipper stretching and de-chaining, and in serious cases, the chain link is stuck between the bearing seat and the tail wheel, which pulls up the tail wheel as a whole. After researching, the gear shaft of the tail wheel of the dry zipper is changed to gearless drive, and the screw in the tail is tightened and lengthened. Extend the dry zipper tail screw tensioning device, from the original 250mm screw, to 400mm long. The chain pitch is 300mm, when the screw is tightened to about 350mm, the screw will be loosened to intercept a chain link, which effectively ensures the chain tension. After the transformation of this program: due to the dry zipper chain length caused by the chain and tail wheel engagement chain failure will be eliminated.
3 Experience and Lessons
In the past few years, although we have learned a lot of things and made some progress, but there are still many shortcomings. First, the management of equipment is relatively rough, lack of detailed and continuous management methods. Secondly, the maintenance of equipment, maintenance is not comprehensive. In view of these shortcomings, we should work harder in the future, not only to be able to bury our heads in our work and forget about our work, but also to be able to check and check every detail of our work when we go back to our work, summarize and analyze our work experience, from how to reduce the failure rate, reduce the cost of maintenance, how to save time, how to improve efficiency and so on, and try our best to make our work procedural, systematized and structured, Streaming! Thus, in the 100-foot pole, one step further, to reach a new level, into a new realm, creating a new chapter for better future work, sum up the experience, lessons learned, for the long-term development of my plant to make new achievements.
