Summary of mechanical design engineer's work

Summary is a kind of applied writing, which is to think rationally about what has been done. Below I collected the work summary of mechanical design engineers for your reference. Chapter 1: summary of mechanical design engineer's work

It has been more than half a year since I entered the company in a blink of an eye. When I first arrived, my heart was always full of fear, but now my heart is really full of a sense of belonging. I have a better understanding of the company's management and corporate culture, and I have made my work direction and goals clearer. Looking back on 2xx, there are both the sureness and joy of harvest and the regret and guilt caused by lack. Under the guidance of the leadership, I have better integrated into this tense and rigorous atmosphere, successfully completed various tasks, greatly improved my professional quality and working ability, and gained more confidence in my work. In the middle of this half year, I participated in many product designs and benefited a lot from them. I not only learned a lot of professional knowledge, but also had a more comprehensive understanding and grasp of the ignition technology in power plants, and cultivated the basic qualities that I should have as a mechanical design engineer. The specific summary is as follows:

1. Work achievements in 2xx years (in chronological order)

1. Improved design of air filter

According to the functional characteristics of old air filter and the actual situation of field installation and maintenance, the equipment structure is modified to achieve better installation and use performance.

2. Participate in the design of double-excitation atomizing nozzle

According to the design ideas of leaders and combined with the old drawings of Apex, the irrationality was changed to make the nozzle more exquisite and powerful.

3. Design of micro-oil gun

Combining with the newly designed double-excitation atomizing nozzle, a new oil gun specially used for micro-oil small oil gun technology is designed.

4. Participate in the design of fuel purification regulator

According to the overall design of Manager Guo, disassemble and refine the part drawing design. This is a relatively fine and detailed process. At first, I didn't fully understand Manager Guo's design intention, and there were some deviations. Finally, after communication and research, I thoroughly understood the design ideas and successfully completed the design task. I feel very lucky. I have worked with Manager Guo to design products. He is a dynamic authority figure with high professional quality and good personality, and he gave me a comprehensive understanding of combustion technology in a short time. At present, two prototypes have been produced.

5. Design of small oil gun

This project is a product designed for the reconstruction of burners of No.3 and No.4 boilers of Luoyang Shuang Yuan Thermal Power Co., Ltd., which is completely designed according to the requirements of Luoyang Shuang Yuan Thermal Power Co., Ltd.

6. Design of high-pressure combustion chamber

According to the design task under Manager Guo and referring to the old drawings of Apex, a high-pressure combustion chamber suitable for micro-oil gun was designed. Two schemes are designed for selection.

7. Participate in the burner design of No.3 and No.4 boilers in Luoyang Shuang Yuan Thermal Power Co., Ltd.

No.3 and No.4 boilers in Luoyang Shuang Yuan Thermal Power Co., Ltd. are new products, specially designed for the burner reconstruction of No.3 and No.4 boilers in Luoyang Shuang Yuan Thermal Power Co., Ltd. For this project of Luoyang Shuang Yuan Thermal Power Co., Ltd., we specially went to Luoyang Shuang Yuan Thermal Power Co., Ltd. for on-site surveying and mapping. At first, I thought surveying and mapping was a simple job, but when I started to work at the site, I found that this job was not as simple as I thought. This job could only be carried out if it entered the boiler, and it was dirty and hot inside. Under the leadership of Manager Guo, we carefully measured each burner and took photos, for fear of missing any important links. After the measurement inside the boiler, we also surveyed and photographed the connecting joints outside, and obtained a lot of information. This surveying and mapping work has greatly touched me, especially the meticulous and serious work attitude of Manager Guo, which has benefited me a lot. I participated in the design of this product under the guidance of manager Guo. At present, the drawings have been designed, and the drawings will be published after review.

8. Participated in the design and production of publicity color pages

Because our combustion technology is not a newly established department, our publicity materials are lacking. In order to better achieve the effect of publicity, manager Guo asked to make publicity color pages. For this reason, I have produced a large number of product pictures from various perspectives for the promotion of colorpage design production. Due to the limitation of ability, the typesetting of color pages was transferred to Wang Gong. Then, after several times of checking and filling in the gaps,

finally, it was audited by the leaders and finalized. The effect of color page printing is very good.

9. Design of Xu Burning Burner

According to the photo appearance and mapping data, the burner is designed (the design is in progress).

Second, 2xx years of learning achievements

In 2xx years, I focused on studying the assembly module of catia software, mastered the latest tools of mechanical design, broadened the design ideas and improved the design ability in combination with the development of machinery industry and the actual situation of the company and myself. In order to improve the design level, I taught myself welding technology. The purpose of learning is to apply. In the future work, I will seriously consider fully applying the new technology I have learned to design by going up one flight of stairs.

the improvement of work style in 2xx years

"It takes three years to sharpen a sword, and now it shows you". After more than three years of work, I have completed the complete transformation from school to society, abandoned those unrealistic ideas and devoted myself to my work. As my work became more and more handy, I began to think about how to make new achievements in my work in order to realize my own value. I have always been positive and unwilling to lag behind. I keep telling myself: I must do everything well and go all out. Through-3-years of fear, I deeply realize that carefulness and preciseness are the qualities that designers should have, and mastery, similarity and innovation are the key factors that determine whether designers are mediocre or excellent. I want to make my design ideas more and more open, I want to enjoy the design, and I want to make a difference in the mechanical field. Doing things with all my strength and rigorous and meticulous work attitude should be the biggest gain in my 2xx work style.

fourth, where we have not done enough, we

lack the courage to take responsibility independently. When encountering problems, I like to ask others to solve them, but I can't make a decisive decision. Later, I solved one problem after another, only to find that things were not as complicated as I thought, and I lacked the courage to take responsibility independently. Also, my communication skills need to be strengthened. Maybe it's because of my personality. I don't like to talk about it. I just like to work hard. Now it seems that this is far from enough. I need to face customers and communicate with others.

2xx years have passed away in a hurry, and a promising new year is coming to us. The road is long, and the road of seeking is long. I will be full of energy, forge ahead, and make unremitting efforts for the development of the company and the realization of personal values.

Year 2: Work Summary of Mechanical Design Engineer

In the past few years, with the strong support and enthusiastic help of the leaders and the close cooperation of colleagues, in line with the principle of doing things in a down-to-earth manner and working conscientiously, I have successfully completed my own work and the tasks assigned by the leaders, and my personal work ability has made some progress. The work and study are summarized as follows:

1 Professional technical level and business ability

I have comprehensively and systematically studied and mastered the basic theory of metallurgical machinery and professional basic theory knowledge during my college years. After joining the work, these theoretical knowledge has been broadened and improved. Pay attention to learning and mastering new knowledge and technology at work and apply them in practice. The production equipment was reformed by using advanced technology and equipment, such as adding a device to prevent the trolley from "arching" in the back lane of the sintering machine, changing the centralized lubrication of the sintering machine slideway into intelligent lubrication, etc., which greatly reduced the failure rate of the equipment and the labor intensity of maintenance personnel, and achieved good use results.

successively participated in the construction, installation and commissioning of the new 1# blast furnace overhaul project in different places, and participated in the compilation of Operation and Maintenance Regulations for Sintering System Equipment, Maintenance, Repair and Management Control Instructions for Pelletizing Equipment and Maintenance, Repair and Management Control Instructions for Sintering Equipment in No.2 Ironmaking Plant. After several years of work accumulation, the professional and technical level has been greatly improved.

2 master the operating parameters and status of 6m sintering and 4,-ton pelletizing machinery and equipment, so that the equipment can operate in a safe, stable and efficient state. Make the maintenance cost of equipment more reasonable and reduce the labor intensity of workers.

2 main work achievements

2, 1? 1) Be responsible for the maintenance, maintenance and transformation of equipment during the overhaul of sintering in 2xx No.2 Ironmaking Plant. The ignition system of sintering machine was reformed by overhaul time, and the igniter burner and preform were moved down by 1mm, which shortened the length from burner flame to material layer, saved gas consumption and achieved good economic benefits. Add a discharging plate at the bin mouth of disc feeders 1#, 2# and 5#, and the angles with the original discharging mouth are 32, 27 and 27 respectively. By changing the angle of the discharging mouth, the blanking position can be changed. After starting, the position of the blanking point changes, and iron-containing materials are evenly distributed in the middle of the skirt belt, which reduces material leakage and improves the accuracy of batching. During the overhaul, the slide and track of the sintering machine trolley will be replaced together in this overhaul. When finding the track, the height of the right track will be determined by the slide height of the sintering machine. Finally, the sealing device of the sintering machine will have a 5mm compression gap under its own weight as the standard. During production, the trolley runs well and the air leakage rate is obviously reduced. 2) Be responsible for the repair, maintenance and transformation of mechanical equipment during the overhaul of 4,-ton pellets in 2xx. During the overhaul, the disc body of 1# pelletizer was mainly replaced, and the quality and quantity were guaranteed in a limited time, and the one-time test run was successful. The rotor and casing of circulating fan in pelletizing workshop are worn quickly and have a short service life due to excessive dust at the inlet. The rotor and casing should be replaced every three months. After research, the wear-resistant lining board is embedded in the fan shell, and the rotor blades are surfacing with wear-resistant covered electrode. After being put into use for 6 months, the effect is good, which greatly reduces the maintenance cost and labor intensity. During the period, the grate bed gap of the grate is adjusted uniformly to prevent the ball from leaking from the grate plate gap. 3) Completed the transformation project of bag dust removal in sintering and screening building of No.2 Ironmaking Plant.

　2、2 ? At present, I am responsible for the mechanical and technical work of sintering and pelletizing workshops in the Second Ironmaking Workshop in the Ironmaking Plant, responsible for the planned overhaul, emergency repair and daily maintenance of mechanical equipment, participating in or organizing the analysis of related equipment failures, participating in the revision or replacement of mechanical equipment operation and maintenance procedures and supervising their implementation, preparing the plan for submitting and reporting spare parts and materials, and implementing the inventory, accuracy, arrival and use of spare parts and materials. Ensure the stable, accurate and reliable operation of the mechanical system. In order to meet the demand of production technology, some equipment in the area has been reformed to make it run more perfect, stable and efficient.

　2、3 ? Equipment renovation project

21) After many years of operation, it was found that when the trolley came out from the rear lane along the curve, there was a phenomenon of "arching" of the trolley, that is, the rear wheel of the trolley was lifted up and could not contact with the lower rail of the lane, and the arching height was unequal. Every hour or so, the lower trolley fell and hit the rail. This phenomenon became more and more serious with the longer operation time, so it must be solved.

2 The specific scheme is as follows: firstly, according to the highest arching height of the trolley in the return lane of 6m sintering machine, determine the processing size of the curved rail, find the mechanical design manual to confirm the cross-sectional width of the 38kg/m heavy rail, and determine the width size of the curved rail; Secondly, draw the drawing, rivet and weld the blank, and then go to the metalworking workshop for drilling and boring the plane. The fixed way of curved rail should be welded firmly, and the height should be greater than the bulging height of the trolley, so that the trolley can level itself uniformly when passing by. At present, the trolley is running well, and there is no large-scale rail smashing phenomenon. At present, this technology has been popularized and used in 1# and 3# sintering machines in ironworks.

2) Complete the transformation of the online vibration detection device of the main sintering exhaust fan. The main sintering exhaust fan frequently stops due to excessive vibration value, and it is the key to ensure stable and high production of sintering to detect the excessive vibration value in time. When the fan is running normally, the vibration value will not exceed the standard, but when the load of the fan suddenly changes or the rotor is unbalanced, the vibration value of the fan will exceed the standard. At present, the method of detecting the vibration of the fan is manual, and the electric tongs on duty regularly measure the vibration of the fan. This detection method has poor real-time performance, large risk coefficient in the detection process and large data error. After installing the automatic vibration detection and protection instrument, it has been put into use and achieved good results.

3) Complete the project of optimizing dry zipper transmission mode and reducing failure rate. In the sintering production line, the dry zipper head and tail wheel are all geared. When the chain runs for a period of time, the wear of the pin holes of the links is lengthened, which causes the dry zipper to be lengthened and detached. In severe cases, the links are stuck between the bearing seat and the tail wheel, and the tail wheel is pulled up as a whole. After research, the gear shaft of dry zipper tail wheel is changed into toothless transmission, and the lead screw at the tail is tightened and lengthened. Extend the tension device of the screw rod at the tail of the dry zipper, from the original 25mm screw rod to 4mm length. The chain pitch is 3mm, when the screw is about 35mm tight, loosen the screw and intercept a link, which effectively ensures the tension of the chain. After the modification of this scheme, the failure of the chain engaging with the tail wheel due to the long dry zipper chain will be eliminated.

3 Experiences and lessons

Although we have learned a lot and made some progress in the past few years, there are still many shortcomings. First of all, the management of equipment is relatively rough, lacking detailed and continuous management methods. Secondly, the maintenance of equipment is not comprehensive. In view of these shortcomings, we should work harder in the future, not only to bury our heads and work selflessly at work, but also to check every detail of the work when we look back, summarize and analyze the work experience, and summarize how to reduce the failure rate, reduce maintenance costs, save time and improve efficiency, so as to make the work as procedural, systematic, organized and streamlined as possible! Therefore, we can go further, reach a new level, enter a new realm, and open a new chapter, so as to do a better job in the future, sum up experience and learn lessons, and make new contributions to the long-term development of our factory.
