Maintenance, Diagnosis And Repair Of Centrifugal Machines

Maintenance of centrifugal machinery in the chemical and petrochemical production is based, as a rule, on the application of the planned preventive maintenance (BPD). Repair of equipment for This is carried out in accordance with the schedule of cpd a year or more. A major shortcoming of this service is that each of the centrifugal machine has certain peculiarities design and operation, so its failure may occur long before the date of repair, planned in accordance with the spr, and vice versa, the equipment is often displayed in the repair of prematurely when the resource of its elements have not yet worked out. To ensure trouble-free operation of machinery with a simultaneous increase in its turnaround, as well as to reduce operating costs appropriate to transfer technology installation on-condition maintenance, ie, the system of planning and diagnostic repairs (SPDR). This article is devoted to problems of organization of operation, diagnosis and repair of centrifugal machine equipment of refineries on the technical condition. First of all, the article applies to maintenance of centrifugal compressor machines (CCM), centrifugal pump units (TsNA), centrifugal ventilation units (CVA), blowers, smoke exhausts, superchargers, air coolers, motors, drive turbines, operated in routine conditions. Maintenance and repair of machinery equipment maintenance as a single interconnected system, which includes: – every shift system maintenance, monitoring and recording of equipment, conducted on place of operation – the system of continuous and periodic monitoring of the characteristics that define the technical conditions – the system output in the repair and determine its extent on the parameters of technical condition of the centrifugal machines – a system of accumulation, analysis and processing of diagnostic information for the timing of the withdrawal in the repair and determine its volume. .
