水輪發(fā)電機組運行維護要注意什么?
(1)機組運行中,注意調速器油壓表與壓油槽油壓表的指示不能相差過(guò)大。
(1) During the operation of the unit, pay attention that the indication of the governor oil pressure gauge and the oil pressure gauge of the oil pressure tank shall not differ too much.
(2)機組在停機過(guò)程中,應盡量縮短低轉速運行時(shí)間。當轉速下降至額定轉速的35%~40%時(shí),可加閘制動(dòng)。
(2) During the shutdown of the unit, the operation time at low speed shall be shortened as far as possible. When the speed drops to 35% ~ 40% of the rated speed, the brake can be added.
(3)機組在運行中,導水葉的開(kāi)度限制應放在機組大出力的限制位置。當機組起動(dòng)與系統并列時(shí),如發(fā)現調速系統不穩定,可用開(kāi)度限制使其穩定。在與系統并列后,可將開(kāi)度限制放在機組大出力限制的位置。
(3) During the operation of the unit, the opening limit of the guide vane shall be placed at the limit position of the maximum output of the unit. When the unit is started in parallel with the system, if the speed regulation system is found to be unstable, the opening limit can be used to make it stable. After parallel with the system, the opening limit can be placed at the position of the maximum output limit of the unit.
(4)定期檢查主軸的擺度。
(4) Regularly check the swing of the spindle.
(5)機組運行中,還應定期做如下工作:
(5) During the operation of the unit, the following work shall also be done regularly:
1)定期切換壓油裝置的油泵和導軸承油泵,以防電動(dòng)機受潮。
1) Regularly switch the oil pump and guide bearing oil pump of the oil pressure device to prevent the motor from moisture.
2)調速器各杠桿的連接處要定期注油。
2) The connection of each lever of the Governor shall be filled with oil regularly.
3)各汽水分離器要定期放水。
3) Each steam water separator shall discharge water regularly.
4)定期清掃橡膠水導軸承潤滑水的過(guò)濾器。
4) Clean the filter of lubricating water of rubber water guide bearing regularly.
5)機組備用時(shí),定期做橡膠水導軸承備用潤滑水的投入試驗。
5) When the unit is in standby, the standby lubricating water of rubber water guide bearing shall be put into test regularly.
6)定期向蝶閥軸承注油。
6) Fill the butterfly valve bearing regularly.
