摘　　要：江口水电站1号水轮机转轮在运行中产生大量裂纹,为此对转轮进行了改造。为降低转轮制造过程中出现的不平衡量,新转轮在制造厂采用三点称重式静平衡装置进行了静平衡试验。本文详细论述了三点称重式静平衡装置静平衡试验原理及江口水电站1号水轮机转轮静平衡试验过程,通过试验及配重,使转轮的不平衡量小于设计允许值,从而保证了水轮机安全、稳定运行。Cracks were found on the runner of Jiang Kou HPP unit 1 under operation; to solve this problem,modification of the runner was applied to the unit. To minimize the residual unbalance,＂3 pivots weighting＂ balancing method was applied to the runner during manufacturing at the manufacturer. It was detailed described in this paper for the basic principle of ＂3 pivots weighting＂ balancing method as well as the routines of the balancing for Jiang Kou U1 new runner. The balancing test reduced the unbalance to meet the allowable design value by means of balancing weight to ensure the turbine unit operating safely and smoothly.
