Abstract

Abstract: Abstract:A fracture accident occurred to major shaft of the circulating water pump for the super critical unit in a power plant. The fracture of major shaft for the circulating water pump was inspected, through spectral analysis and metallography were hardness test. According to the test results, the causes of c major shaft fracture of the circulating pump were analyzed, and relative precautionary measures were put forward.

Key words: Keywords:circulating water pump major shaft, fracture, inspection, cause analysis;precautionary measures
