Expressing the reliability of the process technologies components

Abstract

Every process defined within a specific technology necessitates the exploitation of equipment with a large variety in structures. Procedures in the technology define the purpose of the component, and in-service operations must be followed according to instructions given and distributed by the manufacturer, altogether with the equipment. The instructions for component operation define the conditions for their reliable component operation and functionality. In addition to the conditions, generally, the components should be used in the optimal scope of allocated working capacities, and should be operating within the limited values of physical quantities defined by the technology process, such as: pressure temperature, flux, velocity, and other physical quantities. Equipment reliability assures the continuity of the technology process, uniformity of the final product quality, higher work productivity and ratability of the installed equipment, increased economic efficiency, etc.

Svaki tehnološki proces uslovljava korišćenje određene opreme koja je po svojoj strukturi raznovrsna. Namena opreme definisana je tehnološkim postupkom, a koristi se prema uputstvu koje propisuje proizvođač opreme i isporučuje zajedno sa opremom. Uputstvo za korišćenje opreme propisuje uslove u kojima oprema može pouzdano ostvariti svoju namenu. Pored uslova u širem smislu, oprema mora biti korišćena u optimalnim opsezima radnih kapaciteta i u graničnim vrednostima fizičkih veličina, koje određuju tehnološki procès, kao što su: pritisci, temperature, protoci, brzine i druge fizičke veličine. Pouzdanost opreme obezbeđuje neprekidnost tehnološkog procesa, ujednačenost kvaliteta krajnjeg proizvoda, veću produktivnost rada, veću rentabilnost instalirane opreme, veću ekonomsku efikasnost i dr.
