The stability analysis,error correction control and project pile protection of the process of circulation water pump house well sinking in the project of two 600 MW units at Jiangsu Zhenjiang Power Plant is introduced,and the suggestion to deal with the problems of well sinking under the condition of soft soil foundation is provided.
Test and research are conducted on stainless dosing pipe leakage section in new-buih circulation water pump house of 300MW unit through the method of chemical component analysis,macro analysis,micrustructure analysis,scanning electron micro- scope analysis and EDS energy spectrum analysis.
The side-inlet rotating filter net is used in circulating water pump station of Suzhou Huaneng Thermal Power Plant. The preliminary design of inlet conduit length is 7.36 times of the diameter of pump suction pipe bellmouth, which is shorter than the normal design of 9D. The results of hydraulic model test show that the design is reasonable.
