Emerson azana SIL 3 yemewe na valve inteko

Emerson yashyizeho inteko ya mbere ya valve yujuje ibyangombwa bisabwa kugirango igishushanyo mbonera cy’umutekano (SIL) 3 ku rwego mpuzamahanga rwa komisiyo ishinzwe amashanyarazi ya IEC 61508. Aba FisherKwigungaibisubizo byanyuma bisubiza ibyifuzo byabakiriya kugirango bahagarike valve muburyo bukomeye bwumutekano wibikoresho (SIS).

Hatabayeho igisubizo, abakoresha bagomba kwerekana ibice byose bigize valve, kugura buri kimwe, no kubiteranya mubikorwa byose. Nubwo izi ntambwe zakozwe neza, ubu bwoko bwinteko yihariye ntibuzatanga inyungu zose ziterane rya Digital Isolation.

Ubwubatsi bwo guhagarika umutekano valve ni umurimo utoroshye. Ibikorwa bisanzwe kandi bibabaje bigomba gusuzumwa neza no gusobanuka mugihe uhisemo valve nibikoresho bikora. Mubyongeyeho, guhuza neza kwa solenoide, utwugarizo, guhuza hamwe nibindi byuma bikomeye bigomba gutomorwa kandi bigahuzwa neza na valve yatoranijwe. Buri kimwe muri ibyo bice kigomba gukora kugiti cyacyo no guhuriza hamwe gukora.

Emerson akemura ibyo bibazo nibindi atanga injeniyeri ya Digital Isolation yo guhagarika valve inteko, yagenewe buri gikorwa cyihariye. Ibice bitandukanye byatoranijwe byumwihariko kugirango byuzuze ibisabwa. Inteko yose igurishwa nkigice cyapimwe cyuzuye kandi cyemejwe, hamwe numero imwe yuruhererekane hamwe nibyangombwa bifitanye isano bisobanura ibisobanuro bya buri gice cyinteko.

Kuberako inteko yubatswe nkigisubizo cyuzuye mubikoresho bya Emerson, ifite amahirwe menshi yo kunanirwa kubisabwa (PFD). Rimwe na rimwe, igipimo cyo kunanirwa kwinteko kizagera kuri 50% munsi yo guhuza ibice bimwe bya valve byaguzwe kugiti cye kandi bigakusanywa numukoresha wa nyuma.
