双电公司200MW机组EH油系统改造的若干问题

Problems Encountered during Upgrading of EH Oil System for 200 MW Power Generating Set

介绍了双电公司200MW机组EH油系统改造中发生的问题,如油动机动作异常、蓄能器漏泄、EH油系统压力过低等问题。分析产生问题的主要原因,并且提出解决问题的具体方法。同时,对EH油管道的安装、EH油温的控制及再生装置的运行等问题加以重点论述,并提出建议,以确保EH油系统安全稳定运行。

The problems encountered during up grading of EH oil system for 200 MW power ge nerating set,such as abnormal operation of oil-driven machine,leakage from energy acc umulator,and excessively low pressure in E H oil system,are analysed for causes,and as a result,specific solutions are proposed f or these problems. Meanwhile,installation of EH oil pipeline,EH oil temperature contr ol and opeation of regenerator are discusse d,and ways and means are proposed to ensure safe and stable operation of EH oil system .
