一、备用油源的作用备用油源对于水电站机组的安全运行具有重要的意义。尽管在实际运行中动用备用油源的工况极少,同时也并非所有机组都必须装设备用油源,但是对于担负重要负荷的大型的机组来说,特别是在没有装设蝴蝶阀或快速闸门的情况下,妥善地配置可靠的备用油源将是不容忽略的问题。当机组主用油源失压或其油压降至不足以推动导水机构接力器关至全关所必要的压力时,便需要备用油源自动(推开停机管道上的差动阀)投入,完成事故停机的任务,以保护机组安全地摆脱逸速的危险。
First, the role of spare oil Source spare oil source for the safe operation of hydropower units of great significance. Although spare oil sources are rarely used in actual operation and not all units are required to have a source of oil for installation, for large units with heavy loads, especially without a butterfly valve or quick In the case of a gate, it is an issue that can not be neglected to properly configure a reliable backup source. When the main source of the unit is out of pressure or the hydraulic pressure drops below the necessary pressure to close the complete closure of the water transfer unit relay, an alternative source of oil is required (pushing the differential valve on the shut-off pipe) , The completion of the accident shutdown task, in order to protect the unit safely escape the risk of Yi speed.
