\"2017 Work Summary: Work Summary of Electrical and Instrumentation Engineers\" (Statistics completed)

Thread Content

In 2017, under the leadership of my department head, I held myself to high standards in every aspect. We have always started from the work checklist for reliability engineers, taken ensuring the proper operation of equipment as a prerequisite, and actively cooperated with various inspection and maintenance tasks. With the goal of reducing maintenance costs and improving equipment reliability, we continue to move forward by constantly learning and drawing lessons from experience. I continuously improved my professional qualities and skills, and successfully completed all tasks. I. Management of electrical instruments: A series of daily management systems that meet current requirements, such as the \"Electrical Management System,\" the \"Monitoring and Measurement Management System,\" and the \"Procedures for Periodic Verification of Class B Instruments,\" have been further implemented and improved. In line with the department’s management approach, a general RCM analysis form for electrical instruments was developed, along with a list of electrical instrument devices covering the 6.3 elements, thereby laying the foundation for improved management. Each production unit has established a register of key instruments, and formulated strategies for managing spare parts, including instrument records, lists, material numbers, and safety stocks. At the same time, within the AAA measurement management system, key measurement processes were identified, an inventory list was created, management regulations for these key measurement processes were established, and specific implementation methods for monitoring them were put in place. Complete the annual plan in accordance with the scheduled timelines; the series of PPM plans are gradually integrated into SAP, thereby establishing an effective closed-loop system. II. Electrical instrument maintenance plays a crucial role in daily equipment maintenance, technical upgrades, and emergency repairs, ensuring the healthy and efficient operation of the units and production processes. After the 9-expand-15 modification to the BPA unit, the two new blowout level gauges installed in the crystallization tower failed to operate stably; in severe cases, they would malfunction several times a day, posing serious challenges to process control and safety. I led the maintenance personnel in a calm analysis, concluding that the accumulation of steam condensate in the pressure guide tube was the direct cause; we then developed a solution plan, and after the modifications the problem was completely resolved. The high-pressure refrigeration units often experience malfunctions during operation; initially, it was assumed that the problem lay in the high-pressure cabinet. After repairs were carried out by the manufacturer, the issue persisted. Given the hidden nature of this fault and its connection to vibration, I focused on these characteristics and conducted repeated tests together with the maintenance staff. Eventually, the cause of the problem was identified: it was due to a displacement in the mechanical interlock mechanism. By making adjustments, this difficult issue was resolved, ensuring the normal operation of the special epoxy production facility. The diesel engine used for power generation stopped working during operation; the operators and maintenance staff had never encountered such a situation. The equipment was supplied by the vendor, who was unable to provide timely technical support. Upon close inspection, it was found that the so-called normal shutdown occurred after the supply of liquefied gas was interrupted; the problem likely lay in the air-to-oil ratio, with too much air being used. The issue was resolved after adjusting the oil return pressure. While actively cooperating with the maintenance of electrical instruments to meet production demands, efforts are also being made to improve electronic maintenance records, thereby continuously enhancing the technical skills of the maintenance staff. Giving people fish is a principle that is applied throughout the year’s professional maintenance work; by making full use of actual maintenance cases for on-site explanations, a basic understanding of the 5Y logical analysis approach was developed. At the same time, actively participate in activities to repair and reuse items, fixing spare parts that have value for restoration and reuse. In total, more than 20 repairs were carried out on various types of instruments and meters, saving over 100,000 yuan in spare parts costs. III. Shortcomings in work in 2017 I am fairly aware of the problems and shortcomings that arose over the course of the year, and there are still many areas that require improvement: the awareness of communicating about issues in work needs to be strengthened ； There is room for improvement in enhancing the preventive and predictive maintenance system ； The maintenance of BPA’s programmable valves and the operational reliability of the PBT pelletizing machine need to be improved; these will be areas of continued focus next year. IV. Work Plan for 2018: Continuously improve coordination with various workshops, enhance communication and coordination channels, and on this basis establish a platform for functional and professional collaboration ； It is necessary to implement process quality control in inspection, maintenance, and repair work ； Reduce the costs associated with the use of spare parts ； It is necessary to continue improving the management of high-power motors ； Continue to improve the management of key electrical instruments ； Continue to improve power supply reliability. It is believed that, with the proper guidance of the department and the full cooperation of all workshops, by continuing to explore new horizons in management and technology, adopting new methods and technologies, and staying innovative, we will be able to carry out our work in 2018 in an effective manner, striving constantly to maintain the stable operation of production facilities and improve their reliability!
