摘要
中原大化集团公司的关键联锁系统的执行机构大多采用液压油驱动,如脱碳吸收塔的溶液出口阀XV05001、甲烷化炉的入口阀XV06001等.正常生产时,液压油在P01、P02液压油泵的驱动下,通过油管进入液压闸阀的上部,通过电磁阀带动错油门,推动活塞使阀开或关.在油管管道上装有油压高报警开关PSHA06006、油压低报警开关PSLA06007和油压低联锁开关PSLL06008,其信号引入PLC,通过PLC控制油泵电机的运转,从而控制油压.
The constituent of control system for hydraulic oil station and its control process are briefly described,the improvement of secondary logic program are made in allusion to the existing problems,and the improved effect thereof os also summarized,
