摘要

汽轮机完成数字式电液调节系统改造后

主油泵为原调节保安部套提供大量油源的作用已不复存在

造成了运行中主油泵的富裕油量大量浪费

经过对发电机空测密封油系统的改造

可使主油泵通过安装一附加装置对空侧密封油系统供油

从而节省能源

提高了机组的运行可靠性。

Abstract

After completion of rerofitting the governing system of a steam turbine into a digital electrichydraulic (DEH) governing system

the function of main oil pump for supplying large amount of oil to the original complete security governing set hadn’t existed

resulting in largely wasting the abundant oil capacity of the said main oil pump in operation for nothing. Through retrofitting the oil sealing system on the air side of generator

the main oil pump can supply oil to the oil sealing system at the airside via an additive facility

thereby large amount of energy can be saved

and the reliability of unit operation being enhanced.
