Summary of technical work of thermal control specialty (I) Summary of 20 years' work of thermal control specialty in maintenance department. In the past 20 years, with the correct leadership and strong support of the company and departments, the thermal control specialty of maintenance department has overcome the problems of few personnel and heavy tasks through the efforts of all thermal control maintenance personnel, intensified the efforts to eliminate defects, carefully organized # 1 #2 units, and always adhered to the production of "safety first, prevention first". Focusing on the minor repairs of two units and taking the construction of "five-type teams and groups" as the carrier, we will further strengthen the internal management of the specialty and strive to improve the safety technical skills of professionals. It has laid a good foundation for better completing all the tasks in 20 years. The main work of thermal control major in maintenance department for 20 years is summarized as follows:

I. Safety in production

Safety management is a constant and unremitting work. 20 years, although there are few thermal professionals and heavy tasks. However, the thermal engineering specialty always adheres to the concept of "safety first, people-oriented", and safety production is above all else, and safety production is the most important thing, so that the employees of this specialty can realize that it is our own need to do a good job in safety. In the process of work, we must explain the safety measures and pay attention to the implementation of the safety measures while insisting on the arrangement of work. On the premise of ensuring personal safety and equipment safety, carry out equipment overhaul and maintenance. Therefore, no personal injury or accidents occurred in 20** years, and no first-class obstacles or accidents caused by misoperation, maintenance quality and equipment damage occurred. There were 47 safety learning activities, and thermal work tickets were handled 176, and 176 were qualified, with a qualified rate of 100%.

1, strengthen the supervision and management of important equipment maintenance.

In 20** years, in order to ensure that the equipment is not damaged and protected from misoperation by human factors,

Our major has formulated strict regulations on the maintenance of important equipment. Professional managers must participate in the whole process of monitoring when maintaining important protection and equipment systems, as well as in places where working at high altitude, so as to ensure the correctness of protection actions and the reliability of equipment maintenance. In addition, strict rules have been formulated in the work of thermal logic inspection, input and output, entry and exit of electronic room and engineer station, so as to ensure that there is evidence to check and follow.

2. Strictly manage the "work ticket" in the process of work, and strengthen the role of dangerous point analysis in maintenance work.

In 20** years, this major has carried out special study activities on working ticket system for a long time, which is practical and makes all work signers and responsible persons more familiar with and master the handling of working tickets. In terms of work ticket management, we have strengthened the whole process management of "work ticket" to ensure the implementation of "work ticket" for maintenance work; In order to solve the security risks in the maintenance process, we have improved the analysis content of dangerous points, and analyzed in detail the possible personal injury dangerous points and control measures in each work process. Through two measures, one is to ensure the safe operation of the unit during maintenance and the safety of maintenance personnel and equipment during maintenance. Strictly implement the working ticket system, strengthen technical training, and use technology to ensure safety; Strengthen the training of the person in charge of the work to ensure that the safety measures listed in the working ticket are correct and perfect; Strengthen the management of unqualified working tickets, completely put an end to the phenomenon of signing working tickets, and make the whole process management of working tickets from filling, issuing, licensing to the end of work in accordance with the standardized management system, thus ensuring the safety of maintenance work.

3. Strengthen the study of the personnel on duty on safety regulations and relevant rules and regulations, so that the personnel on duty can guide our on-site maintenance work in accordance with the requirements of regulations and norms during the maintenance process.

During the team morning meeting every day, the professional supervisor ensures that the work of the day is rewarded. For each job,

Characteristics and safety precautions shall be analyzed and discussed by the person in charge of the organization and members of the working group. When the analysis is not thorough and comprehensive, everyone should complement each other to ensure that the safety measures are feasible and the dangerous point analysis is comprehensive and meticulous. This major has carefully studied safety regulations, organized weekly safety learning activities, studied safety regulations and related rules and regulations, discussed the rules and regulations promulgated by the company, monthly safety reports and other factory safety accidents, and formulated relevant anti-accident measures by analogy. Conduct on-site torture and technical questions and answers for the players after work. In 20** years, we have made efforts to standardize and institutionalize our on-site maintenance work, and used rules and systems to guide our maintenance work, trying to avoid arbitrariness in our work; Conscientiously implement the safety responsibility system, make it clear that the professional supervisor is the first person responsible for the safety of this specialty, and make clear the safety responsibility and earnestly perform it.

4. Seriously carry out spring inspection, safety evaluation and autumn inspection.

In order to implement the 20** year work deployment and requirements of the group company and the operating company for safe production, according to the notices of spring inspection, safety evaluation and autumn inspection, this major formulates rectification measures according to the unsafe factors and potential safety hazards exposed in the inspection, lists the responsible person and the planned completion time, and checks the rectification situation within the planned completion time. Self-examination was carried out in the rectification work, and many unsafe factors and potential safety hazards were found. Deal with the problems found in time. Create favorable conditions for completing various tasks throughout the year and ensure the safe and stable production of the unit throughout the year.

5. Carry out "Safety Activity Month" activities.

In June, 20**, under the unified deployment of the company and the maintenance department, this major launched the "Safety Activity Month" activity, set up an organization, with the supervisor as the team leader and all staff participating, formulated a detailed activity plan, and refined the training content, implementation time and specific person in charge. Teams and/or groups (in the enterprise)

Supervisors and technicians organize "safety classroom activities", thoroughly study safety production laws and regulations and safety work procedures, guide employees to establish a sense of obeying rules and discipline, and advocate "obeying rules and discipline, starting from me". Participated in the first aid drill organized by the department, and improved the emergency handling ability. He also studied Twenty-five Key Requirements for Prevention, Safety Regulations, Accident Investigation Regulations and Two-vote Management, and combined with the actual working characteristics of his team, tried to integrate theory with practice. And this year, we will focus on safety training for minor repairs of # 1 and #2 units to avoid violation of regulations.

6. Insist on regular work.

A lot of work, including routine maintenance work, is carried out in the form of routine work. Therefore, if we do the routine work well, we will also do the whole thermal work well, so as to ensure the safe operation of the unit. In view of this idea, we have invested a lot of manpower and material resources to carry out formal work. Specifically, there are the following aspects;

1) Inspection and calibration of protection pressure switch, main components, protection relay and instrument.

2) Check the important parameters regularly. Such as belt scale, oxygen content and other economic parameters.

3) Assign a special person to be responsible for the work of DCS system. Under the guidance of DCS system maintenance guide, according to the actual situation of our company's DCS system, corresponding measures are stipulated, and patrol inspection is carried out once a day, and records are made. Through the patrol inspection, find the abnormality in time and deal with it in time. At the same time, take advantage of the opportunity of major repairs to conduct comprehensive maintenance and various tests on the DCS system, including various redundancy, switching tests and sanitary cleaning, to ensure the reliable work of the DCS system, and make regular backups of the DCS system.

4) Regularly inspect the on-site equipment, find hidden dangers of the equipment in time, and do a good job of inspection.

Summary of Thermal Control Professional and Technical Work (2) Time flies, and five and a half years have passed in a blink of an eye. Since I entered the electric power field in July, 20**, under the guidance of the director of the thermal control group of the technical support department and the old masters, I have changed from an ignorant apprentice to a thermal control technician who can think independently and preside over on-site technical work, and my own quality has been greatly improved. At the beginning of this year, reviewing the work in the past five and a half years, although there were not many remarkable achievements, we also got a lot of tests and tempering from many on-site practical work. In order to sum up experience, carry forward achievements, overcome shortcomings, and improve personal professional and technical level and ability, I will briefly review and summarize my work in the thermal control major from July 20** to June 65438+February 20**, and ask the company leaders to correct me!
