Aiming at an oil supply interruption and bearing bush burnout accident in a steam turbine lubricating oil system,an analysis was made of the operation parameters before and after the accident.
针对汽轮机润滑油系统断油烧瓦事故现象,认真分析停机前后运行参数,在确保安全运行前提下,提出了不揭缸、不解体转子对轮和不找转子轴系中心的处理方案,并在短时间内恢复机组正常运行状态,经济效益和社会效益显著。
Through engine start control and recalibration of deceleration fuel cutoff(DFCO) mode,engine start is achieved at higher speed,DFCO operation zone is enlarged,engine speed is reduced when engine stops,and turn on / off engine ECU frequently is avoided,engine fuel economy and emission will be improved.
介绍了采用继电器对发动机管理系统ECU的工作进行控制,同时针对发动机管理系统原有的减速断油模式进行了重新标定,实现了发动机高转速起动功能,且降低了停机时的转速,避免了对发动机ECU频繁的通/断电操作及因频繁起动造成的发动机燃油消耗率和排放性能的不良影响。
