I. In-depth and detailed preparations before overhaul

1. Check equipment operation records and related technical files. Including operation logs, defect records, accident and obstacle abnormal records and reports, the number and conditions of exit short circuits, statistical analysis of equipment in long-term operation of load, pressure, temperature, temperature rise and related parameters of excessive and abnormal changes, generators Report of inspection test of equipment after short circuit with transformer outlet. The technical file includes equipment factory test and handover acceptance reports, preventive test reports over the years, records and reports of major repairs, etc. By reviewing and analyzing these materials, it proposes items and contents that need to be inspected and repaired during overhaul.

2. Prepare the technical organization plan for maintenance engineering. The main contents are: division of labor organization, construction projects, schedules, construction plans for special projects, technical measures to ensure construction quality and safety, and on-site fire prevention measures, a list of main construction tools and safety tools, a list of spare parts and main materials Table, drawing construction drawings according to the situation of the maintenance site, including maintenance and safety equipment placement diagrams, spare parts and materials placement diagrams, equipment parts and parts placement diagrams after equipment decomposition, etc.

3. According to the construction plan, put forward a plan for spare parts and materials supply. After approval, the material department will be responsible for completing. Some parts and materials that cannot be purchased in the market should be contracted with the relevant departments to be provided or commissioned by the manufacturer, and the quality and quantity should be provided on time.

4. Provide necessary training for maintenance personnel. In addition to organizing all maintenance personnel to learn maintenance process regulations, quality standards, safety work procedures, and construction technical organization measures, new personnel should be trained as fitters before maintenance. For those who have not participated in the overhaul of similar equipment, special training is organized to master the principle of equipment construction and overhaul technology.

5. According to the maintenance work, it is necessary to arrange the lifting equipment or mechanical appliances in advance, and place at a height of 2m and above from the ground for high-level operations, set up scaffolds in advance and take technical measures to prevent falling.

6. Delineate construction equipment, safety equipment, spare parts and materials, placement of accessories and parts after the equipment is decomposed at the maintenance site.

7. Prior to the start of maintenance, the unit leader or the person in charge of maintenance will conduct a comprehensive inspection of the above preparations together with the biotechnology and safety supervision personnel, so as not to start without the conditions.

Second, do a good job of various management tasks in overhaul

1. Pay attention to the inspection work before the equipment is opened and repaired after disassembly. Although a large number of investigations and analysis of the technical condition of the equipment were carried out before the overhaul, and a more detailed technical organization measure plan was prepared according to possible problems, some equipment defects and internal hidden dangers need to be inspected and tested after the cover is opened and disassembled. It was found that in order to ensure the quality and duration of maintenance, the original plan should be revised and supplemented in a timely manner.

2. Strictly implement the responsibility system for inspection and maintenance. With "good" as the premise and "quick" as the standard, vigorously promote the "5S" work method, requiring each employee to strictly implement safe operating procedures and safety production bans, and implement "industrial fire, access to restricted space operations, temporary use Electricity, aerial work "safety management regulations. During the maintenance work, the system of "work dispatch" and "work item quality certification" is strictly implemented. Make sure that everything is implemented, that everything has standards, and that everything goes well. The team divided the daily maintenance work into urgent, light, dangerous, and key points, and rationally deployed personnel according to the maintenance situation to achieve their best.

3. Strengthen the supervision of maintenance quality and strictly implement the acceptance system. After the start of the maintenance, although each part of the work is "the division of labor and responsibility," but it is still difficult to ensure that everyone's work quality meets the requirements. In order to ensure the quality of maintenance, in addition to organizing the acceptance inspection of the component segments, we also have a number of quality supervisors, who focus on the key points of equipment maintenance, and are responsible for supervising and inspecting the inspection process and quality of each post.

5. Pay attention to maintenance records. Maintenance records are a very important basic management work and an indispensable historical archive of equipment. We include this work in the maintenance responsibility system. Each maintenance position must designate a person to be specifically responsible for it, and clearly put forward specific requirements for records, and issue various record forms and recording papers to ensure that the equipment Inspection, test and treatment (including inspection site, inspection method, test items, technical status, problem found, treatment situation and effect, etc.) are kept detailed records.

6. Carry out self-inspection and self-improvement activities with the theme of "finding problems, finding shortcomings, grasping rectification, and promoting refinement". Strengthen safety management, team leaders walked on the scene, inspected inspections, and eliminated hidden dangers, thereby completely eliminating the occurrence of hidden dangers. Strictly implemented the "three systems" to implement an outsourcing contract mechanism for each employee, implemented a safety responsibility system, and carried out all operations. Security measures are in place, and no process is allowed to be omitted. Because there is no standard for valve maintenance work in the past, maintenance has been performed for many years after disassembling and repairing the valve. Although the maintenance procedure is not problematic, it directly affects the appearance. Through the study of sibling units, I have learned methods that are both beautiful and effective. We immediately came back and rectified immediately. We wiped off the butter of the 122 valves in the boiler room, all the screws were rusted and polished, and refueled for maintenance, and the paint was fully painted in accordance with the standard. In this way, the repaired valves will be maintained and beautiful. .

7. Strictly manage the "three standards" at the maintenance site. Strictly follow the standard site layout requirements to standardize the site standard layout, and mark all equipment in the boiler room and heat exchange station, the flow direction of the pipe network, the color of the pipe network, and the ground as required. After the work is completed, tools, utensils, and materials waste should be cleaned up in time to ensure safe production and clean production. Standardization of operations is strictly implemented in all tasks. Developing a good habit of "safety first, prevention first" is effectively reducing human error. Standardize the employees' safety behavior in maintenance and production, implement various safety measures, improve the consciousness of safe production, and ensure safe production.

8. Establish awareness of energy saving. In strict accordance with the equipment maintenance content and requirements, the equipment is fastened, lubricated and repaired to eliminate dirty, loose, leaky, and bad phenomena, so as to start from the fine details and start from a small place. A section of iron wire and each bolt are used to their full potential without wasting a trace of waste. Effectively control the material collection, improve the material collection system, and strictly control the use of materials. Based on the principle of being able to save, use, and receive as much as possible, such as wipes, brushes, etc. can be reused in the case of reuse, No new materials will be issued. Work on saving materials and repairing waste and waste, mobilize employees to repair tools and utensils, re-use used cotton yarn, old gloves and other waste items, re-clean and reuse them effectively, and repair and reuse old valves unloaded during maintenance, etc. . Mobilize employees to check the water pipes, valves, computers, electric lights and other equipment in the hospital carefully every day before work. Every office must ensure that the lights are turned off and the computer is stopped to effectively eliminate the waste and loss of materials.
