Main Inlet Spherical Valve Trunnion Bushing Replaced in Pushihe Pumped Storage Power Station

抽水蓄能电站主进水球阀动作频繁,枢轴轴套设计合理为球阀可靠稳定运行奠定基础。蒲石河抽水蓄能电站2#和4#主进水球阀枢轴轴套为普通铜轴套,由于厂家设计制造缺陷,易导致枢轴轴套破碎。论文主要介绍了球阀枢轴轴套更换施工方法,重新加工球阀轴套注油孔,为同类型球阀枢轴轴套更换提供借鉴和参考。

Main inlet spherical valve opens and closes frequently in Pumped-storage power station,the Trunnion Bushing design is reasonable for the reliable and stable operation of the spherical valve to lay the foundation. No.2 and No.4 main inlet Spherical Valve Trunnion Bushing is ordinary copper sleeve in Pushihe Pumped Storage Power Station, Because designing and manufacturing defects will cause the trunnion bushing brokage. This paper mainly introduces the trunnion bushing of the spherical valve replacement construction method, Remachining valve sleeve oil hole, Replacement and provide the reference for the same type of spherical valve trunnion bushing.
