Principle of blade angle adjustment of circulating water pump in AP1000 unit and adjusting method

Abstract

Abstract: Abstract:The basic situation of the circulating water pump of AP1000 nuclear power unit was introduced. The blade angle adjustment mechanism of the water circulating pump, the adjustment principle and the adjusting method of the blade control unit were expounded. The reasons of faults of the blade control mechanism occurred in commissioning and operation period were analyzed, and the preventive measures were proposed.

Key words: Key words:AP1000 nuclear power unit, circulating water pump, blade, control unit, fault, preventive measure
