In 20xx years, under the leadership of leaders at all levels of the company, all employees of our machine maintenance department strictly abide by various rules and regulations and strictly demand themselves from all aspects. Always adhere to the actual situation of the workshop as the starting point, to ensure the normal operation of equipment as the premise, to reduce maintenance costs and shorten maintenance hours as the goal, and sum up work experience and lessons in continuous learning. The working environment of mechanics is complicated, dirty and tiring, but every member of our mechanics group is diligent and willing to work, carry forward the spirit of unity and unity, and constantly improve their professional ethics and professional skills. Therefore, all the work was successfully completed in a series of challenges, which laid a good foundation for the workshop to complete all the production tasks on time. In order to always do a good job in the service of logistics personnel and ensure the normal operation of each section, the work this year is summarized as follows:
(1) Strengthen management to ensure safe production.
Safety is the basis of sustainable development of chemical enterprises. Our machine maintenance team always abides by all the rules and regulations of the factory, and every employee strictly demands himself to carry out all the maintenance work under the premise of "safety first". Our mechanic is mainly responsible for the repair, maintenance and maintenance of all kinds of machinery and equipment in the whole factory, with a wide working area and many operating points, so safety in production is particularly important to our mechanic class. To this end, the team summarizes the experience and shortcomings of the previous day's work at the morning meeting every day, corrects the problems in time when found, and always reminds and urges the team members to pay attention to safety, so as to nip in the bud, put an end to violations and let the safety alarm ring. Strengthen the standardization of safety production in maintenance work. The purpose is to enhance the sense of security of all employees, strengthen the sense of responsibility, and put an end to carelessness and luck. Our team always pays attention to and checks the potential safety hazards and hazards around us at work, so as to nip the potential safety hazards in the bud and prevent the occurrence of safety accidents.
(2) Strengthen team building and team management.
Team building and team management are the foundation and foothold of doing a good job in the enterprise, and the most important thing is to give play to the innovation and unity of team members. In the usual maintenance work, strengthen the theoretical study of team members and better master them.
Master operational skills, improve their own quality, constantly learn new management concepts, deal with problems in a timely and decisive manner, be brave in taking responsibility, give play to team performance and tacit communication, and let team members make more suggestions to contribute to team building.
(three) to overcome the difficulties of maintenance and promote the full completion of production tasks.
Our machine maintenance team has ensured the normal operation of the equipment in the whole factory this year. Except for normal shutdown, there is no equipment damage or shutdown caused by improper management or maintenance failure, and the equipment operation rate is over 99%. Moreover, a lot of work has been done in the related technology and safety transformation of equipment, and the task has been completed with good quality and quantity. Especially in this year's10.7 ~10.19 plant-wide overhaul, all the members of the machine maintenance team showed a tenacious style of not being afraid of hardship and fatigue. The overhaul was originally planned 13 days, and our machine maintenance team made all preparations in advance. Although there are few people, we have broken the previous maintenance mode and set up three working groups, with the backbone as the team leader. Everyone has a clear division of labor, unite as one, work continuously for more than 10 hours every day, and fight in their own maintenance work. After a few days, the tired figure always appears on every employee, but no one complains that he is tired. Finally, with the concerted efforts of all employees, Qi Xin 1 1 day successfully completed the maintenance tasks of air compressor, oxygen compressor, synthetic gas compressor and coke oven gas compressor.
(four) to strengthen the maintenance force, improve the overall quality of team members as the goal.
Cultivating a machine maintenance team with both ability and political integrity has always been the focus of our machine maintenance team. To this end, the machine maintenance team always puts the professional skills training and learning of its members in the first place and makes unremitting efforts. In order to improve the overall technical level of machine maintenance personnel and enhance their practical operation ability, young employees can get started by themselves under the guidance of external experts, gradually contact and repair key parts, and actively listen to the opinions of external experts. In this way, we reformed four coke oven gas compressors one by one, found hidden dangers in time and eliminated them at any time. Under the guidance of the manufacturer, the bearing seats of four compressor motors are treated with electrostatic insulation and re-aligned; 3# electromechanical main bearing bush (west side), 4#
Replace the main bearing bush (east side) of the electromechanical machine, and the oil supply system of four compressor motor bearings is changed from active oil supply to forced oil supply; Replace the crankshafts of low-pressure cylinders of 2#, 3# and 4# machines, and replace the four-stage packing, piston ring and support ring of 2# and 4# machines to reduce the wear of piston rods; Check and tighten the piston lock nuts of each cylinder of four compressors one by one to eliminate abnormal sound, and replace more than ten sets of big head tiles of four compressors normally. Re-adjust the air separation oxygen compressor and turbine, check the bearings of the air compressor and turbine, and measure and adjust the power. Check and adjust the wattage of the rear bearing of the synthetic turbine. In this year's maintenance, we found our own shortcomings, but it improved the technical level of the players and enhanced the sense of cooperation among the players. The stable operation of two coke oven gas compressors, three steam turbines and compressors is the crystallization of the labor and wisdom of all members of the machine maintenance class, and it is also the driving force for our continuous progress.
(5) Control the maintenance costs and replace the old ones with new ones.
Advocating "saving glory, wasting shame", saving is to create profits, protect the environment, is the core competitiveness of enterprises, but also the key to success or failure of enterprises! Improve the utilization rate of resources, strengthen the concept of saving and improve the saving measures. Our goal is to completely eliminate the leakage in the workshop. During this year, the maintenance team repaired more than 50 compressor valves, made pipe supports from scrap steel in the whole workshop, and actively undertook more than 2,000 mechanical tasks such as water vapor leakage, air separation, technology and canteen, valve replacement, gasket replacement, bearing replacement, water pump maintenance and pipeline addition, which greatly ensured the stable operation of equipment, reduced consumption and ensured production.
(six) to strengthen the management and coordination of the maintenance and transportation team.
Because the peripheral maintenance of our factory is contracted out, it is our machine maintenance team that manages it. The arrangement of daily maintenance work tickets, the handover of maintenance tasks with various workshops, and the negotiation arrangement of tools and instruments are all very detailed. The lack of personnel and technical force in the maintenance team often restricts the smooth progress of maintenance work, and management and coordination often encounter some troubles. However, our machine maintenance team overcame the pain, coordinated in time, conducted comprehensive command, and avoided interruption or maintenance as much as possible.
Make mistakes and actively complete various maintenance tasks. In order to ensure production, our driver maintenance team has also undertaken the emergency repair and maintenance of circulating water pump and rectifier magnetic pump for many times. In the future management work, we will continue to increase and strengthen the management of the transportation support team, so as to make a strong guarantee for the long-term operation of the whole plant equipment.
Looking back on the coming year (20 12), the machine maintenance team has made some achievements, but it also exposed many of our shortcomings:
(1) Our fitter has less maintenance, so it is more difficult to maintain the compressor, especially for urgent repair, and it is difficult to guarantee the maintenance time.
(2) There is only one skilled fitter in the transportation team, so the maintenance of frequently running equipment cannot be carried out at the same time, which restricts the maintenance progress.
③ The technical and professional level of employees and their understanding of the overall situation still need to be strengthened;
④ The ability to analyze and solve problems is lacking, and the ability to deal with problems independently needs to be strengthened;
⑤ Insufficient safety education for on-site transportation teams. Next, we should strengthen the ideological quality construction of employees and strengthen the study of combining business theory with practice; We will further strengthen the safety study and management of the transportation team, redouble our efforts in the future work, learn from each other's strengths, make the team more excellent, and work hard for the future development and growth of the group company.
