皂河站液压减载装置改造探析

Exploration and analysis on the transformation of hydraulic load reduction device in Zao River Pumping Station

液压减载装置在皂河站机组运行中有着重要的作用,经过改造不仅解决了长期存在的渗漏油问题,也方便了各推力瓦压力的读取。机组顶升试验表明在2.5 MPa压力时,可以满足油膜厚度要求,建议液压减载装置在运行时压力控制在2.5~3.0 MPa之间,这样可以减小压力过大造成渗漏油的风险。

The hydraulic load reduction device played an important role in the operation of the unit of Zao River Station.The transformation not only solved the problem of long-term leakage oil,but also facilitated the reading of the pressure of each thrust tile.The lifting test of the unit showed that the oil film thickness could be satisfied under the 2.5MPa pressure.It was suggested that the pressure of the hydraulic load reduction device should be controlled between 2.5-3.0MPa during operation,so that the risk of oil leakage caused by excessive pressure could be reduced.
