摘要

对影响我国超临界、超超临界机组主、辅设备运行安全性和可靠性指标的原因进行归类、总结和分析。结果表明

制造质量不良、施工安装质量不良、设备老化、检修质量不良是影响机组主设备运行安全、可靠性的主要原因

尤以制造质量不良为主;漏粉、漏水、漏汽、机械磨损、堵塞、断裂、振动、冲蚀、开焊等是影响机组辅助设备运行安全、可靠性的主要原因。

Abstract

The factors affecting the security and reliability indices of main and auxiliary equipments for Chinese supercritical and ultra-supercritical generating units were summarized and analyzed.Poor quality of manufacture

installation and overhaul and equipment aging were considered as the main factors affecting the security and reliability of main equipments.While such problems as powder leakage

water leakage

steam leakage

mechanical wear

blocking

facture

vibration

erosion and sealing-off mainly affect that of the auxiliary equipments.
