The fourth is to care about maintenance and participate in it, and functional departments play an obvious role in promoting maintenance. The Mobility Department and the Supply Department respectively organize special inspections on the standardization of on-site materials, power outage procedures, power consumption and materials used in maintenance projects, and standardize relevant procedures and work processes. The main leaders of the office are responsible for the full tracking and coordination of maintenance logistics such as water supply and meal delivery, ensuring the timely supply of drinking water and meals for maintenance workers. The Security Department is responsible for inspecting the factory area and conducting key monitoring of key parts. During the maintenance period, two theft incidents were discovered and dealt with in a timely manner to ensure the safety of factory property. Led by the Production Department, with the participation of part-time safety officers from each unit, maintenance safety management is continuously strengthened.
In the summary, relevant personnel put forward many good suggestions for future equipment maintenance management: Combined with various technical manufacturing work To advance, we need to plan ahead and start from the preliminary preparations to do a better job in various technical transformations and equipment overhauls this year. The maintenance plan must be carefully sorted out and the project review work must be done in place. During the maintenance process, great attention should be paid to the connection between technical tracking management and construction personnel to avoid process disconnection. Based on the equipment maintenance situation in the first quarter, plan the management focus and maintenance projects in the next stage in advance, prepare and consider in advance, and lay the foundation for the next maintenance. Sample Essay 3: Summary of Equipment Maintenance Work
Time flies, and 2017 is about to pass. This year is a milestone year in the development history of the Surfactant Branch. The Second and Fourth Oil Production Plants have successively opened up three-dimensional In composite flooding production and injection areas, the demand for surfactants for oil flooding has increased significantly. In order to ensure the smooth injection of the oil production plant and make our due contribution to the stable production of 40 million tons of crude oil, our workshop has started and stopped the device eight times under the unified arrangement and coordination of the branch, producing 2,645 tons of 1# sulfonic acid, 2 #Sulfonic acid 7920 tons, completed the production task excellently.
The raw material of surfactant sulfonic acid used for oil displacement is the waste from the production of daily chemical products dodecylbenzene. It is composed of a variety of mixtures. In order to achieve product specifications, a higher amount of sulfonate is required during the sulfonation process. Due to the acid neutralization value, the sulfonated components are prone to coking and clogging the distributor and sulfonated tubes during the production process, causing the production cycle of the device to be about 20 days. At the same time, in order to ensure the injection volume, the device only has a maintenance period of 5 to 7 days each time it is shut down. Sometimes even only 2~3 days. Almost all equipment maintenance is done in a rush repair manner. ***Completed maintenance projects this year, including 17 outsourcing projects and 13 self-inspections. The maintenance not only improves the production capacity of the device, but also eliminates some safety hazards of the device. For example: by cleaning the SO3 absorption heat exchanger, the coking sulfonic acid inside the heat exchanger is removed, improving the efficiency of the heat exchanger and greatly reducing the possibility of coking by absorbing sulfonic acid; by correcting the verticality of the sulfonator , calibrate the relative flow rate of the film-forming tube of the sulfonator and clean the heat exchange tube, which greatly improves the operating accuracy of the sulfonator, delays the coking of the sulfonator, and extends the production cycle of the sulfonator; through the melting The sealing modification of the sulfur tank and the constant position tank has eliminated the volatilization of sulfur vapor, reduced the sulfur dust concentration in the sulfur melting room, and improved the operating conditions in the sulfur melting room. In the absence of a unified and regular maintenance period, our workshop strengthened the following aspects of work based on specific maintenance conditions and successfully completed the maintenance tasks.
1. Firmly establish the concept of safety maintenance, use "Five Essence" management as a guide, and implement the "Four Haves" working method throughout the entire maintenance process
1. Break the whole into parts and Based on the inspection data and equipment performance, we make a reasonable maintenance plan based on the principle that no project involving safety production issues is left out, and no unnecessary projects are included. Based on the actual situation that the equipment shutdown period is short and the maintenance period is short, we based on daily points We collect the main performance data of each piece of equipment accumulated during the inspection, organize technicians and operation engineers to discuss the operating data of the equipment, and determine the operating status of the equipment. Guided by the annual maintenance plan, the 2009 maintenance plan is reasonably scheduled within the monthly shutdown and maintenance period.
2. Carefully plan and organize carefully to ensure smooth maintenance.
In order to ensure that all maintenance work is carried out safely, smoothly, orderly and under control, we require each work to have a plan. According to each maintenance project, a professional maintenance meeting in the workshop should be held before each device is shut down to determine This shutdown maintenance project has also revised and refined a series of specific operation plans such as the construction schedule, hot project list, and process replacement plan for this maintenance project.
According to the "Five Essence" management method, we have prepared "Maintenance Procedure Operation Guide" for each maintenance project, which details the work content, construction facilities, tools, protective equipment, etc. of the maintenance project. materials, construction procedures, and standardized maintenance actions.
3. Strengthen the supervision and control of the construction process to ensure step-by-step confirmation.
In order to strengthen the process management of each construction project during maintenance and ensure step-by-step confirmation, we require that the "Chemical Group Construction Work Ticket", "Outsourcing Construction Site Confirmation Form", "Outsourcing Construction Site Confirmation Form" must be executed during the maintenance process. Maintenance tickets and records such as "Project Interface Handover Form", "Maintenance Project Construction Acceptance Form", "Fire Ticket", "Electricity Ticket", "Water Ticket", "Enter Limited Space Operation Ticket", etc., through the implementation of the above operation tickets , so that all items during the entire maintenance operation are under control.
2. Actively cooperate and strictly control the quality of maintenance to ensure that the maintenance is completed as scheduled.
1. From the beginning to the end, the maintenance project implements a dedicated person responsibility system.
In order to ensure the smooth progress of equipment maintenance and strictly control the quality of maintenance, the workshop mobilizes key personnel such as operation engineers and squad leaders to ensure that each maintenance project has a dedicated person on site to take charge of it and does not overlap with each other. The on-site person in charge is the construction progress officer, maintenance quality officer, construction supervisor, construction facilities, and material coordinator of the project. Before the maintenance work begins, the person in charge of the construction site must be familiar with the maintenance purpose, goals, construction content, safety measures, required materials, etc. of the project, and coordinate the materials, tools, and safety protection equipment required for the maintenance to the designated location to prepare for the maintenance. Do a good job in logistics support.
2. Use the maintenance schedule as a guide to arrange the maintenance work reasonably to ensure that the maintenance is completed as scheduled
In order to complete the maintenance tasks as scheduled and with guaranteed quality during the short shutdown period of the device, we have detailed with the maintenance personnel Based on the total maintenance workload, a strict and detailed maintenance schedule and daily maintenance work content were formulated. The workshop requires the on-site person in charge to not rush ahead or fall behind in the maintenance workload, and strictly follow the maintenance schedule. Regarding the progress of maintenance
We implement a "daily report" system. The person in charge of each project site reports the completion of the maintenance work on that day and the work plan for the next day every day. For projects that did not complete the day's workload, we worked with the construction staff to analyze the reasons, formulate rectification plans and work plans, and reasonably control the maintenance time, thereby ensuring that the construction progress was successfully completed as expected.
3. Use the "Four Haves" work method as a guide for maintenance and strictly control the quality of maintenance
During the entire maintenance process, we resolutely implement the "Four Haves" work method and strictly implement the group's According to the relevant management system, the construction team must handle relevant procedures such as "Construction Operation Ticket", "Electricity Use Ticket", "Fire Ticket", "Limited Space Entry Ticket" and other relevant procedures in advance according to the construction progress. If the procedures are not completed, the construction conditions will not be met. We resolutely do not allow construction, and truly do not go through the motions, are not afraid of trouble, confirm every step, and implement every item. The person in charge of the site is responsible for supervising the safety protection measures of the construction workers. Those who disobey the management have the right to stop their maintenance work. At the same time, they will check the quality during the construction process, fill in the maintenance project construction record form, and review the "Maintenance Construction Regulations". Supervise the execution of the work, effectively ensuring construction safety and construction quality.
In terms of quality acceptance of construction projects, we adopt the method of on-site acceptance. The on-site leaders of the construction team, workshop professionals, production office professionals, and project site leaders conduct daily inspections on the construction workload of the construction team. On-site confirmation and recording effectively ensure the accuracy of construction visas and qualified construction quality.
3. Shortcomings in the maintenance work
Under the coordination and organization of the factory production office, and with the joint efforts of all the cadres, employees and maintenance personnel in the workshop, our workshop has achieved " "No fire, no injury to a person, no damage to a piece of equipment" is the safety maintenance goal. This achievement is gratifying, but at the same time we should also see that we have many shortcomings in the maintenance work that need to be corrected in future work.
1. There is a phenomenon of rush to construction in some construction projects. There are two reasons for this phenomenon: on the one hand, it is because the workload is overestimated when formulating the maintenance construction schedule; On the one hand, it is because the construction workers rush into the construction and rush to the progress of the construction. This is the biggest safety hazard. We must resolutely put an end to this situation in the future.
2. The details of individual maintenance procedures are not standardized enough. Since our workshop is conducting large-scale maintenance for the first time and lacks maintenance experience, the details of the maintenance operations of very individual equipment are not thoughtful enough, which is not conducive to actual practice. Operations need to be summarized after maintenance, draw inferences from one instance, and revise other maintenance procedures.
