Key Technology Research of Large and Medium-sized Generator Set with Double Bearing Barring Gear
Based on the actual situation of the Zambia Kafue Gorge Lower Hydropower Station under construction,the feasibility of double bearing barring gear is analyzed,the detailed technological process of double bearing barring gear is discussed,and all the data and standards are analyzed,and the preparation work before barring is carried out.The data in the process of barring are measured and recorded,and the data are processed and analyzed according to the net throw and full throw formula,and the optimal solution of the axis is obtained.Compared with the traditional single bearing barring,the double bearing barring method has the advantages of reliable quality,time-saving,accurate,easy to be analyzed,efficient and convenient,etc.,that could provide technical support for the construction of hydropower stations in the future,and will greatly promote advance of the construction technology of water conservancy and hydropower industry.
