离心机组长周期运行的探索

Exploration of Long Period Operation of Unit

随着机组的长周期运行,机组表现的安全隐患逐渐表露出来,特别是二套ARGG的机组已运行20多年,由于原有设计思路的不完善,导致出现大量的生产隐患,例如:联锁大多为单点,未采用二取二或三取二,特别是有些重要的参数(如烟机振动)没有采用联锁;机组由于设计缺陷,存在大量的漏油现象等隐患。为此,这些年通过技术革新对机组存在的隐患进行整改,使机组控制方案变得更加合理,现场隐患逐渐降低,有利的保证了机组长周期安全运行。

Along with the long period operation of the unit,the safety hidden danger of the unit performance is gradually revealed,especially the two sets of ARGG units have been running for more than 20 years,because of the imperfect design ideas,resulting in a large number of production hidden dangers,such as:interlocking is mostly single point,not two or three,especially some important parameters(such as smoke machine vibration)did not use interlocking;Because of the design defects and a large number of hidden dangers such as oil leakage,the unit control scheme becomes more reasonable and the hidden trouble on the spot is gradually reduced through technological innovation in these years.Favorable to ensure the safe operation of the machine leader cycle.
