降低维修费用是延长航线寿命的重要因素,假如能继续改进设备的使用期限的话,航线上的设备周转就会更快,例如,延长发动机元件的寿命是特别重要的,在航线维修工场的分部用于另件修理的费用就有数百万美元。Northwet Orient 航线维修分公司的机械附件部的管理人 Roy Hoit 认为:“采用使用寿命较长的设备可以加快设备的周转,由于维修的减少使得保养高价设备所需的费用随之减少”。在特定的情况下,用磁性密封代替装有旋转轴上的弹簧负载密封,可使设备检修前的使用寿命显著增加,使用磁密封增加了使用寿命,这样就减少了维修工时以及另件需 Reducing maintenance costs is an important factor in extending the life of a service. Equipment turnover on a service route can be faster if the service life of the equipment can be continuously improved. For example, it is particularly important to extend the service life of engine components. Millions of dollars are spent on the repair of another item. Roy Hoit, manager of the mechanical attachments department at Northwet Orient Route Maintenance, said: “The longer service life of the equipment can speed up the turnaround of the equipment as less maintenance is needed to maintain expensive equipment.” In specific cases, replacing the spring-loaded seal on the rotating shaft with a magnetic seal results in a significant increase in service life of the unit prior to overhaul and the increased service life with the magnetic seal, which reduces maintenance man-hours and the need for additional parts
