5 generator s seal oil pad and seal oil system in Huaneng Dezhou Power plant 3rd phase project,the analysis held that,when single flow ring-seal pad was used,the basic cause for seal oil flow abnormal increasing during start-up was the rising of lubrication oil temperature.
结合华能德州电厂三期工程5号机组发电机密封瓦及密封油系统的工作状况,分析了采用单流环密封瓦发电机组在启动过程中密封油流量异常增大的根本原因是:润滑油温度升高密封油箱油位降低是因为密封油系统供油量增大,而从主油箱来的补油量少于供油量造成的。
6) centrifugal seal of magnetic fluid
离心式磁流体密封
补充资料：磁流体密封
用铁磁流体封堵泄漏通道的半流体动密封（见图）。Fe3O4·CrO2等铁磁性超细微粒悬浮在低挥发性的液体中，形成铁磁流体。将铁磁流体置于密封间隙中，在磁场力作用下铁磁流体能形成强韧的液体膜,借以阻止泄漏。磁流体密封常用于密封气体,适用于密封高真空系统。它可用于高速，但不耐高温和高压。
