摘要
介绍了双流环式密封油氢侧油路发生的平衡故障,分析指出平衡阀因油质差而卡涩是故障发生的主要原因,汽轮机低压缸胀差过大也会使平衡阀失调,提出更换新的平衡阀及更换被磨损的瓦块等处理措施。
An introduction is being presented to the balance fault occurring in the hydrogen-side oil path of a double-loop sealing oil system. The problem is found to be caused by blocking in balance valve due to poor oil quality, and the too large differential expansion of turbine low-pressure cylinder may also cause unbalance of the valve. Corresponding countermeasures are put forward, such as replacing the old balance valve with new one and changing the worn out pad, etc.
