Abstract:

Abstract:To select the balancing device is an important link for multistage pump design. In a nuclear power project, eccentric abrasion of the balancing plate occurred after performance test of the starting feed pump. The reasons of the abrasion were analyzed. Some measures were adopted to improve the assembling precision. Then the performance test was carried out again, and the abrasion of the balancing plate did not occur again. The normal operation of the pump set was ensured.
