Ningde Power Generation Company 2 ×600 MW unit has 88LKXA-20 type circulating pump 4

Jiangxi Guixi electric power plant project department to undertake the circulating pump maintenance

from February 2007 officially entered the maintenance so far. Circulating pump is not stable operating conditions

the pump running excessive vibration

reducing the equipment operating life. Had to overhaul technical regulations from the research innovation

breaking part of the conventional processes

the use of advanced technology

innovative process for the purpose of the circulating pump vibration value drops

reducing the defect rate. Applications can be proved through practice inspection technology innovation to achieve tangible results

improvements in technology have practicality and maneuverability. Technological improvements aimed at key nodes through the pump and a major overhaul process was analyzed and discussed

technological innovation.The Ministry of nearly two years of the project to improve the use of good maintenance process overhaul 3B and 3A circulation pump quality

vibration within 0.02 mm/s

a record of success.
