Abstract: Electromechanical equipment operation reliability is the purpose of design and manufacture, as well as the stage of creating value and playing function efficiency. Aiming at the poor operation reliability, low running efficiency, poor matching with process production and poor self-adaptive control of domestic electromechanical equipment, the concept of remanufacturing engineering in service is proposed, and the remanufacturing in service theoretical framework, which comprise applicable object, project objectives, design basis, life cycle and engineering value, is constructed. Remanufacturability in Service assessment is the precondition of remanufacturing for electromechanical equipment. Health level assessment, reliability evaluation and efficiency level evaluation are carried out based on the condition monitoring data, reliability data, maintainability data and analysis data. The personalized redesign is executed based on data-driven decision-making, and then the Remanufacturability in Service evaluation index system and evaluation model are constructed to quantify Remanufacturability in Service. The static blade adjustable actuator for axial-blower with high failure rate, poor operational reliability are often suffered valve position locking or running out of control in the fluid catalytic cracking unit(FCCU), the traditional electro-hydraulic control system is remanufactured in service. Application case proves that Remanufacturing Engineering in Service can create huge economic and social benefits.
