In the case of rapid economic development, various industries are inseparable from the application of machinery. With the continuous improvement of market demand, various types of machinery have been developed and popularized the application of mechanical design and processing put forward high requirements. Here are some of my personal work summary on mechanical design, for your reference.
Mechanical design personal work summary essayTime flies, years like a shuttle, 20xx has passed away inadvertently. Looking back to 20xx, both the harvest of solid and joy, but also due to the inadequacy of the regret and guilt. 20xx is the company's great development of a year, the dynamic test machine market is good, the development of the work of the Department of the four is heavy and arduous, I am in the guidance of the turner and the gross workers, better integrated into this tense and rigorous atmosphere, and better to complete the various tasks, their own business qualities and work ability has been greater. Improvement, have more confidence in the work. In the past year, I participated in more product design, from which I benefited a lot, not only learned a lot of professional knowledge, a more comprehensive understanding and grasp of dynamic products, but also cultivated me as a mechanical engineer should have the basic quality. At the same time, I insist on self-study, learning the current mechanical industry new tools and software and professional books, improve the theoretical level. Now the specific work is summarized as follows:
First, the work achievements in 20xx (in chronological order)
1. Design, debugging exported to India motorcycle testing machine
The trip to India was successful, but also difficult and memorable. Our team of three, in the absence of a translator, overcame the difficulties of the local hot weather and dietary discomfort, and in less than three weeks time will be four sets of equipment debugging is completed, to get the user's acceptance of the minutes, which is worthy of recognition. However, I think there are also some regrettable places. Because it is the first time to do the export of vehicle products, lack of experience, our packaging and rust prevention is not good enough, equipment failure, so that the Indian people's satisfaction with us declined. If we pay attention to these details and use our products to open the door of India, a country with a fledgling industry, then I believe we will benefit from it.
2. Supervisor design PWS-J20B1
This testing machine has been handed over to the completion of the inspection, the indicators have reached the requirements of the technical agreement, and so on the user to the shipment of money.
3. Participated in the design of PWS-200B
Designed with Mao Gong, the hydraulic chuck, pneumatic-hydraulic booster pump and other working principles have a more in-depth understanding of the work from Mao Gong learned a lot of things. For example, the rigor and seriousness of the design, this product has been shipped.
4. Participated in the design of PWS-250C
Designed with Mr. Mao, which has passed the user's pre-acceptance.
5. As the project leader in technology, design NW-DYB200
This project is a new product, completely new design, and short design time, difficulty, it is a severe test for me. Zuo Gong is very strict with me, looking for MTS and other product information for
Let me refer to, gave me a lot of autonomy, after efforts, and finally completed the design task. At present, the mechanical part of this product has been installed, waiting for the controller debugging.
6. Participate in the design of QPNS-200H7, QPSB-200
These two products are also new products, and the structure is complex, at the beginning of the project I was set as the project leader, but in the design I obviously feel the lack of their own ability, coupled with the project's critical period, there is an urgent matter at home, I took a leave of absence for nearly three weeks, delayed the design of the time, the left worker to undertake a lot of work that should be done by me. I y regret and thank you. This two million products, I am a very good training, so that I recognize their own shortcomings, and at the same time to thank the left worker taught me a lot of things, because of these two products, I have matured a lot.
7. Participated in the design of the PNW-B5000
I participated in the design of this product under the guidance of the Cheongsong, and the drawings have been designed, waiting for the user to review the drawings out of the drawing. I think I am very lucky, and the turner, Mao Gong and Bei Gong have cooperated in the design of the product, they are all high business quality, good character dynamic authority figure, it is they let me in a short time to have a more comprehensive understanding of the dynamic products.
Mechanical design personal work summary essay twoXX year is about to draw a period, 20XX year's footsteps have gently to us, looking back into the Huaxing Nuclear Power Installation Company this six months, there are happy and lost, sweat and tears of excitement. From the blazing sun in July out of the ivory tower of the university, slowly into the company's safety, honesty, excellence in the work atmosphere, we are growing, the company is making progress, I would like to use my efforts in exchange for greater development of the company!
July 30, 20XX, with the Huaxing head office of the new staff of ten days of corporate culture and occupational health education training ended, I was assigned to the nuclear power installation company, and then we entered the intense training and learning. Nuclear power is, after all, a minority of people can understand things, for just entered the company we are two eyes a black, the heart both worry, but also have a sense of mystery, the working principle of nuclear power is what? What is the working principle of nuclear power? Will we suffer from nuclear radiation when we work in the future? These questions haunted us. From August 1 to September 4, we had a month of basic nuclear power training, I understood the development of China's nuclear power and the status quo, and more y appreciate the necessity of China's future development of nuclear power, in the lectures of the old staff, we listened attentively to the lectures, and they carefully prepared the lessons and made the vivid courseware, so that we understood some basic knowledge about the installation of nuclear power, and we understood our company's role in the upcoming construction of the Chashma nuclear power plant in Pakistan. Chashma nuclear power plant in Pakistan to carry out construction of C3 \ C4 we implement some of the regulatory documents, so that we have the bottom of the heart! Although the nuclear power installation company has just been established soon, but I believe that there are all the old staff carefully and carefully prepared for the work, with the leadership of the head office of the strong support of our employees work together, the future of nuclear power installation company more exciting!
Subsequently I was assigned to the coal chemical Tongliao Project Department of Hurray Engineering Company Limited, began their own internship process. My major is water supply and drainage engineering technology, in the school learning, focusing on municipal engineering, came to the Tongliao project department for the first time under the scene, I was shocked, a root of industrial pipeline such as human blood vessels to support the production of the plant, I heart silently ask myself:? Can I cope with the work at hand in the future? At the beginning I was assigned to the following shift, to all the master workers to help, although a little hard, but I slowly familiarize with the environment, slowly learn to change. I suddenly feel that the pipeline is actually the same, just we face the unfamiliar things timid, I also slowly adapt to the beginning of the experience and summarize some things. In the field of work, I know how to group the pipe, the general process of pipe installation, know how to use the manual hoist, once let me shocked by a thing is, a DN400?12 stainless steel pipe in the manual hoist lifting, ? Aerial relay? Successful positioning in the pipe corridor. I also got to know some commonly used tools and machines, such as knocking plum wrench, plasma cutter, and flared wrench. I also practically operated the sander, plasma cutting machine. Understand what argon arc welding is all about, and what argon gas shielded welding is all about.
Into October, the new esterification transformation project of the smooth handover of civil construction, I was sent to another group, dry materials clerk. If the site work in September let me understand the workflow, then this duty let me really recognize what we need to construction, a variety of pipe fittings and how different. In the process of receiving materials, I learned that flanges have flat weld flanges, flat weld flanges with necks, butt weld flanges with necks, and that there are flat surfaces, protruding surfaces, concave and convex surfaces, and tongue and groove surfaces. I also learned about valves such as gate valves, globe valves, pneumatic valves, quick-opening ball valves, oxygen valves, socket weld gate valves, filters, flame arrestors, etc. I also learned that flange gaskets are metal-wound gaskets, asbestos gaskets, and PTFE gaskets. In the process I also understand some common sense in pipeline construction, such as pipeline and equipment touching, should be the first flange mounted equipment and then lifting pipeline welding. This month's practice, let me learn a lot, but also let me mind a lot of doubts to be solved.
Came to the Tongliao Project Department although no shift, but because of the new esterification transformation project is small, so like mechanical, electrical group, I also have some understanding. In the esterification transformation, I participated with the mechanical group to witness the lifting of the new ester tower, as follows:
I also once went with the mechanical group to give a workshop to a pump coupling to find the right, these experiences allow me to initially understand the installation of the work of the project in which the other professions are responsible for the content of the work.
Into November, with the basic end of the overhaul, the project department gradually transferred to the plant some sporadic technical reform of small jobs, and the pipeline technician also take advantage of the project is not tight, go back to visit his family, I will act as a few days of the technician. Although it is some small work, I do not dare to take it lightly, I often take the initiative to communicate with the party to contact, to help workers open electricity, fire tickets, in this series of small work exercise I understand what a technician should do. First of all, we must have good communication with the A party, really understand the construction intentions of the A party, and put forward their own rationalization proposals to facilitate the construction of workers; secondly, in the field and the A party to communicate with the construction of the content of the heart of the initial plan of the materials needed to facilitate the construction of fast and effective; thirdly, and workers communicate well, do a good job of technical briefings, explaining some of the safety considerations for the workers on site, to ensure that the project is completed successfully. In addition, I also witnessed a few repair tasks, although all night overtime is more difficult, but from the repair I know how to work, how to allocate personnel. The above experience is just the beginning, I believe that with the growth of my experience I will be more skillful.
December, with the advent of winter, the project is basically over, I also began the end of the year the project department data finishing work, under the guidance of the technical manager of the project department, I sorted out the previous stage I am responsible for some of the workload of small jobs, and accompanied by the A side of the personnel for the site audit, looking at the fruits of their labor I am very pleased.
In the work I also found some things I did not learn, such as the application of measurement in the installation. Because it is a technical reform project, so in the pipeline installation drawings are basically no size, it is entirely the workers themselves to measure the size, and then prefabricated prefabricated installation, I think this is not in the installation of nuclear power, especially new projects, as a technician I hope that in the future I can master a certain degree of knowledge of the measurements, so I think this aspect of the work of this half a year I am lacking.
Looking back on these six months, I feel that I really started to enter the work state. Work I actively learn from the master, and at the same time restless to understand the principles of the work process of other professions, although I have learned a few things, but I understand that our final project is a nuclear power plant installation project, it will be more complex, more systematic, I need to learn a lot more. In the new year, I will continue to maintain the enthusiasm of the work, to do a good job in the work at hand to do a good job, with a good face to accept the company's future nuclear power installation work tasks.
Mechanical design personal work summary essay threea, pioneering, good comprehensive management of machinery and equipment
With the development and expansion of highway construction scale, the degree of mechanization of engineering construction has become the key to ensure that the project and the progress, while the number of machinery and equipment and the technical content of a large number of increases, which gives the management of the machine puts forward new requirements. In recent years, I correctly selected the machinery itself the law of operation and the law of the market economy, combined with the actual situation of the unit, carried out a serious exploration and practice, from only focus on the technical management of equipment, physical form management to the ideology of the value of the form and the physical form of the combination of the management mode conversion to economic efficiency, work efficiency as the center for the purpose of improving the unit's economic efficiency services. In line with the objective management of good, micro-activation of the principle, the formation of a set of use, maintenance, repair, as one of the new system.
(a) the purchase of equipment
In recent years, with the increase in the degree of mechanization of engineering construction, the acquisition of equipment has also put forward higher requirements, in the process of purchasing equipment, I follow the principle of two aspects: First, the purchase of equipment before the purchase of the necessary technical and economic demonstration, fully understand the mechanical properties of the equipment, reliability, output, production capacity and engineering Scope of application, combined with the market situation and the actual situation of the unit, to examine the necessity of purchasing equipment, predict the recovery time, as well as the economic benefits it brings; grasp the different offers of the same type of equipment, comparison, so that reasonable. Secondly, the equipment purchased with full consideration of the production situation and equipment development. For example, when I purchased stabilized soil mixing equipment in XX year, according to the needs of the project at that time, I purchased the plant mixing equipment with hourly output of 300 tons of volumetric weighing to meet the use requirements, but I considered the future construction of highway grades on the plant mixing equipment output and quality requirements will be higher and higher, therefore, I suggested purchasing the most computerized measuring WCQ500 roadbed material mixing station at that time to meet the requirements of the highway grades on material weighing, material grading, and material mixing equipment, so as to meet the requirements of high grade highways. Therefore, it was recommended to purchase the then most computerized weighing WCQ500 roadbed material mixing plant, which could meet the requirements of future high grade highways for material weighing, material grading and output. At present, the total value of our machinery and equipment assets has reached more than 40 million yuan, which is more than 30 times of that of 10 years ago, and the supporting system is complete with advanced performance, which has fully equipped with the ability to undertake the construction of high-grade highways. Over the past few years, I participated in hosting the unit of all large-scale machinery and equipment inspection, selection, purchase, installation and commissioning work, and a test machine success rate of 100 percent.
(B) the use of equipment
The correct and reasonable use of machinery and equipment is the main content of the work, it is not only the completion of mechanized construction tasks to ensure that, but also to reduce mechanical wear and tear, extend the service life of machinery, reduce the cost of machinery operation and maintenance costs, improve economic efficiency of the key. In the use of management, I adhere to the principle of man-machine fixed to do? Three fixed? That is, fixed people, fixed machine, fixed position responsibility system, a machine of large-scale machinery, the implementation of the system of responsibility of the machine manager. Requirements for machine operators to do four understand the machinery: understand the structure, understand the performance, understand the principle, understand the use, three will: will operate, will maintain, will remove general faults. Operation of machinery to do four no: no over-temperature, no over-pressure, no over-speed, no overload. At the same time, the construction site machinery for dynamic monitoring, maintenance. Requirements for operators must follow the command of the constructor, correct operation, use in accordance with the regulations, respect for science, give full play to the effectiveness of machinery, to ensure the quality of operations, and do a good job of construction with the construction of the construction personnel in violation of safety regulations and may cause dangerous accidents in the command, the operator has the right to refuse. Require mechanical personnel? Four to the field? That is, mechanical management to the field, mechanical inspection to the field, mechanical work coordination to the field, mechanical failure to the field, so that the mechanical management horizontal to the edge, vertical to the end. At the same time, the implementation of the machinery supervision system, machinery supervisors in-depth construction site, supervise the operation, repair personnel to correctly use, maintenance and repair of machinery and equipment. This ensures the correct and reasonable use of machinery and guarantees the quality of construction.
While doing a good job in the technical management of equipment, strengthen the economic management of equipment, adhere to the economic benefits of equipment management as the center, to the overall efficiency rate as the highest goal. Mechanical team to implement independent, self-financing, according to the value of the equipment owned by the value of assets, the development of the annual contribution amount. The machinery team carries out the accounting system of single machine and single vehicle, taking cost, workload, machinery technical condition and surplus amount as the main assessment indexes, which is directly linked to the salary distribution, and implements the structural salary system according to the pay for the work done. Single-engine single-vehicle economic accounting, to overcome the overall economic accounting of small units appear in the machinery revenue and expenditure imbalance, the responsibility of the door, the performance of the many drawbacks, so that each machine's income and expenditure of the breakdown, and as a measure of economic efficiency, the assessment of the driving operator's work performance. Through the implementation of single machine single car accounting, give full play to the talent, technology, management expertise, improve the utilization of equipment, mobilize the enthusiasm of driving operators, encourage operators to multi-talented, excellence.
In accordance with ? Rent to feed the machine, rely on the machine to generate profits? The new way. According to the actual situation of the unit, I searched for the relevant regulations, formulated the "internal unit cost quota", "external leasing unit cost quota", "rent rules", "leasing management rules", etc., and drew a dynamic distribution map of equipment leasing, leasing economic distribution map. For the longer lease period to give certain concessions, and with the market to adjust the lease in a timely manner, so that they are invincible. In recent years, the Bureau's equipment utilization rate are maintained at 65% or more, more than 90% of the effective utilization rate of equipment, foreign leasing cumulative income of more than 400 million yuan.
(C) equipment maintenance, repair and transformation
Do a good job of maintenance, repair work is to extend the service life of machinery key. I realized in practice, the traditional ? Regular maintenance, mandatory repair? system has great shortcomings, focusing on the economic effects of not paying attention to routine maintenance and repair, so, actively explore new warranty models, and gradually establish a ? Condition monitoring, mandatory maintenance, depending on the repair? The new model. Strengthened the daily maintenance work before, during and after the shift, the implementation of the daily maintenance status reward and punishment system, equipment maintenance personnel to implement piecework pay system and maintenance quality responsibility system. Regularly organize personnel to monitor the status of the equipment and repair as appropriate. And actively explore new maintenance methods, such as: a XX purchase of T-230 bulldozers using Cummins NT-855 engine cylinder liner, every six months to be replaced due to cavitation, I advocate the use of parts displacement method, in the cylinder liner running for a period of time after the rotation of 90?re-installation, effectively extending the service life. After the adoption of the new warranty model, the Bureau's annual maintenance costs reduced by 15% -45%, the failure rate reduced by 65%, greatly improving the rate of mechanical integrity, extending the service life of machinery. During this period, I **** presided over or guided the overhaul of the equipment more than 20 times, of which the larger technical transformation 4 times. First, in XX on the Xi'an asphalt mixture mixer dust and combustion part of the transformation of the part, in the cyclone dust on the basis of manufacturing and installing a water dust removal system, burning diesel oil for burning heavy oil, both saving fuel consumption costs, but also solved the problem of dust pollution of the environment, if calculated according to the utilization rate of 60%, a year of savings of 5-6 million yuan. Secondly, in 1996, the Municipal Highway Bureau eliminated the 14/16-ton road roller made in Texas for nearly 10 years and carried out the repair and transformation, changing the joystick steering into steering wheel steering, and changing the mechanical steering into all-hydraulic steering, which saves the capital of more than 18,000 yuan, and is still in good use, and has been given a higher appraisal by the Municipal Highway Bureau and the original manufacturer. Thirdly, in 1997, he participated in the transformation test of the metering system of Parker-M356 asphalt mixing machine. The number is led directly from the circuit after the signal amplifier and then through the proportional circuit into the PLC (programmable controller). This allows the hardware to be easily used to adjust the number-to-analog ratio. The system was modified to be able to categorize and store the various aggregate, asphalt and powder fits for each pot of material. When there is waste material, it can automatically alarm. Prevent the waste material from entering the finished product warehouse, to ensure the quality of the material. The system is currently running in good condition. Fourthly, in 1998, the WCQ200 stabilized soil plant mixing equipment produced by Shandong Construction Machinery Factory was transformed to increase the mixing pot motor, transform the feeding system, increase the supply of aggregate, so that the output of the equipment was increased from 200t/h to 300t/h, and at the same time, the measurement of powder was changed to the spiral weighing weighing method, and it directly enters into the mixing pot, so that the measurement is more accurate, so that the equipment is permitted to be used in the graded highway, and it has received good results. This allows the use of this equipment in the grade of highway, and received good economic benefits.
(D) mechanical statistics
Mechanical statistics from mechanical equipment to the end of the equipment life cycle throughout the entire process of recording. In the work of collecting a variety of original, good equipment, the establishment of the card work, the handover of equipment, use, maintenance and repair records, large and medium repair records, depreciation records, tire replacement, mechanical operation records, etc. complete and complete, the statistical ledger so that we have mastered all the management of machinery and equipment and the use of machinery and equipment for the assessment of the technical performance of machinery and equipment and provide a basis for the benefits. Through the collection of data summarization, analysis and, timely discovery of equipment management problems and deficiencies, to provide a scientific basis for management decision-making. Thus improving the integrity of mechanical equipment and utilization rate, and thus improve the investment efficiency of mechanical equipment.
