The "Equipment Reliability and Life Extension Management" project (Precision Inspection) is2014years10At the beginning of the month, the project was fully launched at Guodian Nanning Power Generation Co., LTD. (Nanning Power Plant). After nearly three months of intense construction, the project team successfully completed the relevant work.

In accordance with the project implementation requirements, based on the actual situation of Nanning Power Plant and the critical grades of the equipment, from#1,#2It was selected from the crew336All equipment is included in the scope of the precision overall inspection, including boilers, turbines, chemical equipment, coal conveying equipment, and transfer equipment in the desulfurization area200Electrical equipment such as platforms, step-up substations and transformers136"Platform.

In order for the power plant to persistently carry out the "Equipment Reliability and Life Extension Management" project (precision inspection) and make it an important part of equipment management, we have helped the power plant establish relevant organizational systems, work processes, management standards, technical standards and other management documents and systems. It provides a management foundation and institutional guarantee for "Equipment reliability and life extension management" (precise inspection).
