Condition-based maintenance support system of feed pumps in 660MW thermal power generating unit

摘要

In this paper, the current situation of research on condition-based maintenance (CBM) and the implementation of it are introduced. in power plants in China And according to the condition in Shajiao "C" power plant in Dongguan, Guangdong province, a CBM support system of feed pumps in power plants has been developed. With the advanced reliability centered maintenance (RCM) at the core, based on the failure mode and effect analysis (FMEA) for every component of feed pumps, the system will make the optimum maintenance decision according to the results of the condition evaluation and risk evaluation. The satisfying running state of feed pumps in 660MW thermal power generating unit in Shajiao "C" power plant shows that the system is user-friendly, reliable and therefore lays a solid foundation for the CBM of all the equipments in the power plant.
