【 摘 要 】

When a power plant ultra-supercritical 1000MW steam turbine generator set is running normally, the electric valve at the outlet of A steam feed pump appears serious leakage. Through on-site inspection and inspection of maintenance records, starting from the structure of the electric valve, the leakage fault of the electric valve at the outlet of A steam feed pump is diagnosed and investigated, and the cause of the fault is accurately analyzed. The leakage problem of the electric valve at the outlet of A steam feed pump has been thoroughly solved by taking effective measures such as changing the packing type, arrangement and improving the installation process.
