2022 maintenance summary model essay 1

20__ years passed quickly. During this year, I made unremitting efforts, assiduously studied and courageously attacked, and became the "winner" of technology in the station, creating a direct economic value of 6.5438+0.5 million yuan for the enterprise. In the ordinary maintenance post, I won everyone's respect and users' praise with selfless work spirit and skilled maintenance skills, and made due contributions to the development of the enterprise.

First, study hard and strive to be a top technical soldier.

There are roads in the mountains, but the sea of skills is endless. After arriving at the maintenance station, I only know that as a skilled worker, if he can't understand the drawings, the principle of equipment and the structure of vehicles, he will not only be embarrassed, but also be an unqualified worker. I overcame the disadvantage of low education level and "refueled" myself with a kind of "bull's strength" that I won't stop until I reach my goal. In order to buy some useful technical books, I often squeeze some change out of my living expenses to buy books and research skills. I have taught myself technical theories such as vehicle structure and mechanical foundation, and applied what I have 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, if I can't finish it in the workshop, I will take it home to get it. Over time, my home has become my "research institute". Everything comes to him who waits. After studying hard, I have achieved my professional skills. In several technical competitions of cities or companies, I showed my advantages every time and returned to the list. I am not complacent about my achievements. I know that although I am an external employee, the maintenance station has given me a platform to really display my talents. 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 the problem and solve the problem of restoration.

With my intelligence and professional skills, I have solved a series of difficult problems for users, overcome one difficulty after another, and become a trusted "technical expert". Nowadays, any technical problems in the workshop can be solved as long as Master Zhao gets started.

In April this year, the dispatcher informed me that there was a Passat 2 and 0 car, which was forced to downshift. I went to several repair shops and couldn't fix it, so I came to our station to fix it. As soon as the car was repaired, I immediately took the instrument and tested it with the owner. During driving, it was found that when the vehicle speed reached 65,438+000 yards, the fourth gear was automatically reduced to the third gear, and the engine had abnormal noise. The owner said: there was a problem three months ago. I looked for a number of repair shops, but I couldn't find the problem. I repaired it three times in the second pit. I suggest changing the gearbox. I think the cost is too high, so I'll come to our station to have a look and make a decision. I judge that the failure of "insufficient engine power, resulting in forced downshift" is most likely caused by three non-catalytic blockages. The owner said that it had been checked by short circuit method at the second station, and no problems were found. After the test run, I checked it again in detail, and it was still confirmed as three-way catalytic blockage. The owner is dubious, and I promise to the owner that if this problem is not solved well, this site 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 replacement, the fault was successfully eliminated, which not only relieved the user's troubles, but also saved a lot of money. The user said with satisfaction, "The trouble that bothered me for three months was solved in less than three hours. Your maintenance station technology is great."

Third, love and work to meet the needs of users.

"Users are God and must satisfy me" is my work creed. Whenever and wherever a user calls, I am on call. I haven't been home for a long time last National Day. I'm going to take my wife and children back to my hometown to spend the holidays with my parents during the holiday. That day, my wife and I were having our hair cut and dyed in the hair salon. Just in the middle of painting, we received a call from the maintenance stationmaster: a car of the Oil Production Technology Research Institute broke down on Dagong Road in Harbin and needed emergency rescue. I know in my heart that the unit is on holiday and there are insufficient repair personnel. A strong sense of responsibility made me forget to dye half my hair. I quickly asked the barber to wrap my head in plastic film and set off for the scene at once. The wife advised, "Why don't you go when you're done?" I said, "No, the user's help is a silent command. The car broke down on the highway and people didn't know how to worry. " Customers are grateful to see me come to the rescue like this. I went back to the office after troubleshooting the vehicle. It's already past seven in the evening. The user insisted on inviting me to dinner, but I politely refused. The user said: "Your station is not only first-class in technology, but also provides on-site service. That's what I do. I think what users think, worry about their urgency, help their needs, and win the praise of users again and again with my enthusiasm and practical actions.

Fourth, teach the profession as a teacher and teach skills to educate people.

"A flower is not spring, and a hundred flowers bloom in spring." . 15_ You are not only technically excellent, but also enthusiastic about taking apprentices and cultivating talents, giving full play to your light and enthusiasm for the long-term development of the enterprise. I have brought more than 30 apprentices, and summed up a set of "apprentice mentality" of "two hearts" and "three components" in practice, that is, concentrate on skill learning; The actual operation should be "mouth diligent", "hand diligent" and "leg diligent". Insist on every apprentice you bring: be persuasive, set an example, not only teach business skills, but also bring character. Some of my apprentices have taken up technical management positions in the unit, and some have become the production backbone of the unit. Every year, peaches and plums are fragrant, and after each year, I have accumulated talents and strength for the enterprise with hard work and sweat.

20__, I will continue to serve users with full enthusiasm, win customers with excellent technology, contribute to the enterprise with a loyal attitude, and write a touching song of youth in an ordinary post.

Model essay on maintenance work summary in 2022 II

In order to ensure the smooth progress of heating during the heating period of 20__—20__, all employees of the company vigorously carried out energy-saving and consumption-reducing work. With the cooperation of Qi Xin, the residents spent a warm and comfortable winter with a continuous low temperature. In view of the continuous low outdoor ambient temperature, the company promptly raised the heating temperature, and promptly accepted user complaints, handled and measured the temperature, further improving the heating quality and service quality. Looking back on 20 _ _-20 _ _, the heating work has achieved gratifying results, and the safety production and heating quality have reached the standard. These achievements were achieved with the joint efforts of all staff. To sum up, we mainly focus on the following aspects:

I. Guiding safety work with advanced cultural concepts

Our company requires chemical workers to firmly establish the safety concept that life is above everything else and responsibility is more important than Mount Tai, regard safety as the soul of life, the foundation of happiness, the foundation of benefit and the source of stability, meticulously implement the spirit of various indicators of the country, group companies and mines, learn advanced cultural concepts, and actively carry out comparison learning, comparison technology, one-on-one activities and on-the-job training activities. So as to further improve the theoretical knowledge and practical skills of our chemical workers and lay a solid foundation for doing their jobs well.

Second, improve the safety management system and standardize safety management.

At the beginning of the year, the leaders in charge of the mine signed a safety responsibility letter with the boiler safety management personnel, and each chemical personnel wrote a safety guarantee letter, forming a system of self-protection, mutual insurance and joint insurance. After the merger of the property company and the plumbing team, the system was incomplete. The safety responsibility system, safety management system, working standards, operating procedures, potential safety hazards and emergency preventive measures of each post were revised and improved, and uniformly printed and posted, forming an employee insurance team with standardized management system.

There is no boiler equipment and personal accident in the safety responsibility guarantee system of shift mine.

Third, pay close attention to employee safety education and training to create a safety culture atmosphere.

In order to improve the operation skills and theoretical level of chemical personnel, our company actively formulates a training plan for chemical personnel, and holds a safety study meeting for chemical personnel every Friday to sum up the problems existing in the week, find out the gaps and suggestions among employees, and find out the shortcomings in the operation of their own equipment. We use the study time on Tuesday to invite teachers to talk about theoretical knowledge, operation experience and accident cases in boiler operation, and conduct boiler knowledge exercises once a week. We ask our chemical workers to think, ask questions and answer questions next week, and actively carry out on-the-job training and technical competitions. In the whole year, four theoretical examinations of chemical industry were conducted and four on-the-job trainings were organized, with the number of participants reaching 65,438+000%.

Fourth, strengthen equipment maintenance during operation to prevent all kinds of failures.

During the operation of equipment in winter, our company attaches great importance to the maintenance of boilers and auxiliary equipment, and is equipped with two full-time maintenance workers for daily maintenance. It is required to check the integrity of safety accessories in shifts, do a good job of weekly test inspection of safety valves, and do a good job of weekly oil injection of gear boxes, grate shafts, pumps and other equipment. Technicians check the maintenance records every week, and require that no equipment, any parts and any accessories should be omitted during the maintenance process, so as to achieve the high efficiency and safety of the equipment.

Five, energy saving and consumption reduction, technological innovation work significantly.

Small changes to small leather, old repairs and waste utilization, and technological innovation have always been the theme of energy conservation in our company. First, strictly control coal saving. In the process of coal transportation and daily management, we should strictly manage and pay close attention to the burning of coal; During the operation, the fireman is required to adjust the grate speed, coal seam thickness and air volume of blower and induced draft fan in time according to the load of external network, so as to greatly improve the burn-out rate of coal.

High, from the previous 70% to 96%, saving coal 1680 tons compared with last year. The second is to strictly control power saving. The frequency conversion speed regulation technology is adopted for the make-up pumps in each boiler room, which reduces the power consumption. Third, strictly control water conservation. The maintenance team insisted on regular inspection of the external network, which prevented the occurrence of leakage and effectively controlled the water consumption. The fourth is to strictly control environmental protection. Each boiler room is required to take effective measures to ensure that the smoke and dust meet the standards, so as to clean the slag daily and meet the requirements of environmental protection.

1, the pipe network is in disrepair for a long time, with serious corrosion and leakage, which seriously wastes water resources.

2. The service life of No.2 boiler of industrial boiler in a mining area is as long as 20 years, which has exceeded the service life, and it is difficult to maintain and the annual maintenance cost is high.

3. It is difficult to manage the outsourced boiler room, and it cannot be implemented after the work arrangement.

4. The comprehensive quality of employees is not high, and the concept of service quality is weak. During this heating period, users called many times to reflect the problem, but our maintenance staff did not deal with it in time. Finally, users reported to the company's dispatching room and company leaders, which caused a bad negative impact and damaged the company's interests. In the future, we will strengthen the education of employees' service quality concept, strive to improve the overall quality of employees and make positive contributions to improving the company's service quality.

2022 maintenance work summary model essay 4

First of all, I would like to thank the leaders of Tower Power Company for their strong support and affirmation of the air conditioning work in the engineering department in the first half of 20__, and thank all departments for their active cooperation and understanding of the air conditioning work in the engineering department in the first half of this year! Here, I report to the company the completion of air conditioning work in the first half of 20__.

In the first half of 20__, with the care and strong support of the company leaders and the hard work and unremitting efforts of all the employees in the engineering department, we overcame the difficulties of fewer personnel and increased workload, vigorously carried out maintenance and technical transformation to tap the potential, actively solved various problems existing in equipment and facilities, and made a major breakthrough in energy saving and consumption reduction.

I. Maintenance

The air-conditioning equipment in the factory has been running for a long time and is in an aging state to varying degrees. Maintenance and operation are the main tasks of the air-conditioning class. Therefore, strengthening equipment maintenance, improving the service life of equipment and making a scientific, reasonable and complete operation plan are important links to improve operation efficiency. On the basis of improving people's skills, make equipment operation plan and strengthen maintenance, so as to make air-conditioning equipment and facilities in the best operation state, so as to achieve the purpose of rational utilization of energy and saving expenses.

20__, the aged and corroded pipes and fans in the air-conditioning ventilation system were painted for anticorrosion, some air-conditioning pipes were insulated, the range hoods and fans in the office building were maintained, the fillers of two cooling towers, namely centrifuge and screw machine, were replaced, and the water supply butterfly valve (DN200) of the screw machine cooling tower was replaced. Do a good job of moistureproof in the air-conditioning room, repair the control box switch damaged by short circuit due to damp, repair the air-conditioning master switch damaged by deformation in the transformer room, and repair and maintain all the electrical equipment in the air-conditioning room. The centrifugal machine adds refrigerant R 1340, the screw machine adds refrigerant R22, and the 22-meter steam turbine room 1#, 2# and 3# circulation pumps are transformed into vertical pumps. In the computer room, four pressure gauges and five thermometers were replaced, the heat totalizer and flow sensor were calibrated, the heating pipes and valves were maintained, and the pipes, valves and terminal equipment of air conditioning equipment and facilities were maintained. In spring and autumn, the indoor air conditioners are cleaned and maintained twice, such as the filter screen and filter screen of the air return port, and all the unopened air conditioning valves are closed to reduce energy consumption and do a good job of antifreeze in winter. This is the most difficult job, and it took more than four months before and after. Usually, this job needs two people to finish. However, due to the lack of engineers, heavy tasks and heavy workload, the spring maintenance work is basically completed by one person, which undoubtedly increases the difficulty of the work. However, the staff overcame various difficulties, completed this task with good quality and quantity, and maintained the factory 175 air conditioners.

Second, the transformation project

The transformation of central air conditioning is divided into two areas and four major projects.

The renovation of central air conditioning in the factory area is divided into two projects.

Project1:Reconstruction of 22m chilled water circulating pump.

Before the renovation: due to the use of three old centrifugal pumps (IS125-100-315), the equipment acts as a rubber buffer coupling, resulting in serious vibration and noise, and obvious vibration and noise in the centralized control room. Moreover, the old-fashioned water pump adopts oil-lubricated packing water seal, which leaks water and leaks oil. Inviting pump manufacturers to the power plant to guide maintenance, there is no obvious improvement.

After transformation: after changing to vertical water pump, vibration, noise, water leakage and oil leakage are completely solved.

Factory project 2: overhaul of 4 1m air-cooled screw machine. Before overhaul: due to long-term work, there are the following defects. 1. There is moisture in the refrigerant, so the refrigeration effect is poor and the energy efficiency ratio is low. 2. There are impurities in the refrigerator oil, which affect the suction ability and lubrication effect.

3. In the compressor motor, the male and female rotors are worn, the exhaust pressure is low, and the high and low pressure gas channeling reduces the refrigeration capacity.

4. The cooling fan works continuously for a long time, the parts are aging, and the exhaust ability is poor.

5. The condenser and radiator work for a long time, and there are sundries and scales on the pipe wall, which causes poor heat exchange ability and seriously affects heat dissipation and refrigeration.

6. The electrical components in the distribution box work for a long time, causing fever and inflexible movements. Some control and protection circuits transmit unstable signals and equipment fails.

After the transformation, the working efficiency of compressor motor is greatly improved, and the phenomena of poor heat exchange and unstable control and protection of screw machine are completely improved.

The central air conditioning renovation in the office area is also divided into two projects.

Office project 1: overhaul of water-cooled screw machine in reception building. Before overhaul:

1. The cooling tower works for a long time, and the filler ages and scales, which seriously affects the heat dissipation. At the same time, the pipeline in the condenser scales, which seriously affects the heat transfer. 2. There is moisture in the refrigerant, so the refrigeration effect is poor and the energy efficiency ratio is low. 3. There are impurities in the refrigerator oil, which affect the suction ability and lubrication effect.

4. The star wheel of the compressor motor is seriously worn, with high noise, low exhaust pressure, high and low pressure gas channeling and reduced refrigeration capacity.

5. The control module in the distribution box is updated, the equipment is upgraded, and the control module is also updated. After the transformation, the problems of poor heat dissipation, loud noise, low efficiency and oil leakage were completely solved.

Project 2 in office area: overhaul of centrifuges in reception building. Before overhaul: due to long-term work, there are the following defects.

1. After working for a long time, there is a serious shortage of refrigeration oil, which affects the suction ability and lubrication effect. At the same time, it is noisy, poor in refrigeration and large in current.

2. The cooling tower works for a long time, and the packing is aging and scaling, which seriously affects the heat dissipation. At the same time, the pipeline in the condenser produces scaling. Seriously affect the heat exchange. 3. There is moisture in the refrigerant, so the refrigeration effect is poor and the energy efficiency ratio is low.

4. The star wheel of the compressor motor is seriously worn, with high noise, low exhaust pressure, high and low pressure gas channeling and reduced refrigeration capacity.

5. The control module in the distribution box is updated, the equipment is upgraded, and the control module is also updated.

After the transformation, the refrigeration capacity of the compressor is greatly improved. Completely solve the situation of tight refrigeration in office area under high temperature.

In the second half of 20 _ _ _, all employees of our company will meet new challenges with a brand-new mental outlook, and work together with employees of other departments to provide a safe, comfortable and fast working and production environment for Tower Power, and ensure the ambient temperature of key maintenance positions (electronic equipment rooms such as centralized control room, excitation room and inverter room). ), so that the unit can play a higher efficiency. Under the leadership of Tadian, we will continue to grow. We are confident to push the air conditioning work to a new height and a new starting point with practical actions and hand in a qualified answer sheet to the company!

2022 maintenance work summary model essay 5

Graduated from _ _ technical school in _ _, and was assigned to work in the dust removal and desulfurization workshop of _ _ thermal power plant at the end of September of the same year. During this period, with the guidance of leaders and squad leaders and the help of the whole workshop staff, I seriously studied the theoretical knowledge of dust removal and desulfurization operation and equipment maintenance technology, and quickly became familiar with and mastered the actual operation of secondary and secondary equipment, the judgment and treatment of abnormal and accidents in operating equipment, and some basic common sense, routines and various rules and regulations that should be known as a maintenance attendant, which laid a solid foundation for doing a good job in maintenance. During several years' working career, the cordial care of superior leaders and the enthusiastic help of colleagues have made my working ability grow and mature rapidly and become a qualified maintenance worker. Work-centered, diligent, continuous learning and conscientious work attitude is my understanding of my personal career. In my career, I pursue my dreams with my heart and spend my youth. Personal qualities have also been improved. To sum up, there are mainly the following points:

First, the correct working attitude.

In recent years, the rapid development of electric power technology requires all-round development of employees and high quality in all aspects. In order to meet the needs of doing my job well under the new situation, it is my long-term requirement to strengthen theoretical study and constantly enhance the sense of loving and respecting one's post. Always regard continuous learning and comprehensive learning as a great pleasure in life, use spare time to learn relevant professional knowledge, improve your knowledge reserve through online learning in enterprises, and strive to cultivate yourself into a versatile and all-round talent to meet the needs of enterprises. Actively participate in various professional skills and business training organized by the factory, and constantly improve personal skills, self-improvement and development in the process. Since I joined the work, no matter in operation and maintenance, I first found my correct position and made my work goals and work plans for myself. Asking me to master comprehensive business knowledge, how to make full use of my skills and knowledge, and a series of ways to do it will often urge me to establish a correct working attitude and do my job well. Thanks to my continuous efforts, I finally won the praise of the leaders and was awarded the honorary titles of "Asian Employee Award", "Advanced Individual Award" and "Spiritual Civilization Award" by the workshop.

Second, good work style and skilled maintenance skills.

In 20__, I was assigned to the maintenance class, responsible for dust removal and desulfurization maintenance management. In the face of heavy and trivial daily work and hard working environment, I face up to difficulties, use the time I can, study workshop procedures and maintenance knowledge comprehensively and carefully, and arrange every job and every detail carefully and reasonably. At that time, I was mainly responsible for maintenance tasks. In order to make the equipment run normally, I do my duty, study business knowledge hard, fill in maintenance records and maintenance task lists carefully, carefully count various maintenance reports of the team and report them in time. After work, actively communicate with workshop leaders and learn from them the management methods of maintenance team with an open mind. Everything comes to him who waits. Through hard work and the cooperation of my colleague Qi Xin, a set of maintenance procedures more suitable for the normal operation of the equipment is finally summarized. Under my continuous learning, I participated in the welder skill competition of the group company and won the sixth prize.

Third, good team spirit.

In the modern working environment, team consciousness is very important. Effective teamwork can improve work efficiency. To this end, I not only work hard by myself, but also get along well with my colleagues. In addition to learning from each other at work, I often have heart-to-heart talks with my colleagues in my life, understand their inner thoughts, give advice to each other and find ways. As an ordinary maintenance worker, for more than four years, I have inadvertently integrated into the big family of power plants. Looking back at the road when I came, it was still a blue flame shining not far away, which was clearly colorful. Stop for a long time, absorbed in thought, with the power plant in a hurry, looking at the distinctive banner of China Coal Gasification Group. At this moment, I am proud of you, proud of you, and all my passions are burning for you. I still remember the first time I put on the blue professional clothes of the power plant, the kind of inner joy that can't be concealed, the dream came true, bathed in the early morning sunshine, and proudly walked to work. After work, I feel the happiness of dedication quietly, enjoy the happiness of work silently, and purify my mind. Busy is the main theme of my work, and I shape my life without regrets with the happiness contained in love and dedication.
