石化公司乙烯配套装置采用的MCL1003型空压机,为反应单元提供97 000m3/h工艺空气,某日运行中跳车。经查,机组跳车的直接原因是空压机主油泵P-9402B跳车,导致润滑油压力低联锁PSA-352(跳车值0.1MPa)动作,速关油压PSA-009低(跳车值0.15MPa)机组跳车。查历史趋势,润滑油总管压启动,之后油路压力恢复正常值0.270MPa。现场检查润滑油位正常,在确认
Petrochemical company ethylene equipment used MCL1003-type air compressor, the reaction unit to provide 97 000m3 / h process air, a day trip in the car. The investigation, the crew directly to the cause of the vehicle jump is the main air compressor P-9402B trip, resulting in low lubricant pressure interlocking PSA-352 (jumping value 0.1MPa) action, the speed off the oil pressure PSA-009 low Car value of 0.15MPa) crew trip. Check historical trends, lubricating oil master pressure start, after the oil pressure returned to normal 0.270MPa. Check the lubricating oil site normal, confirmed
