Emorson wethula imihlangano ye-VALVE eqinisekisiwe ye-Sil 3

U-Emerson wethule imihlangano yokuqala ye-valve ehlangabezana nezidingo zenqubo yokuphepha yeleveli yobuqotho (i-3) 3 nge-IEC 61508 ejwayelekile. Laba fisherUkuhlukaniswa kwedijithaliIzisombululo ze-Final eyetic izixazululo zisebenzela izidingo zamakhasimende ama-valves avaliwe ohlelweni lwezinhlelo zokusebenza zokuphepha ezibucayi (SIS).

Ngaphandle kwalesi sixazululo, abasebenzisi kumele basho zonke izinto ze-valve ngayinye, bathenge ngakunye, futhi balihlanganise basebenze ngokuphelele. Noma ngabe lezi zinyathelo zenziwa ngendlela efanele, lolu hlobo lomhlangano wangokwezifiso ngeke lunikeze zonke izinzuzo zoMkhandlu Wokuhlukaniswa Kwedijithali.

Ubunjiniyela I-Valve Shutdown yokuphepha ngumsebenzi okuyinkimbinkimbi. Izimo zenqubo ezijwayelekile nezicasulayo kufanele zihlolwe ngokucophelela futhi ziqondwe lapho ukhetha izakhi ze-valve nezazi. Ngaphezu kwalokho, inhlanganisela efanele yama-solenoids, amabakaki, ukuhlanganisa nezinye i-Hardware ebalulekile kufanele kuchazwe futhi kufaniswe ngokucophelela ne-valve ekhethiwe. Ngayinye yalezi zinto kufanele isebenze ngawodwana futhi ikhonsathi ukuze isebenze.

U-Emerson ukhuluma ngalezi zingqinamba nezinye ngokunikeza umhlangano we-shuared wedijithali we-digital isolation valve, enzelwe inqubo ngayinye. Izakhi ezahlukahlukene zikhethwe ngokukhethekile ukwanelisa izidingo zohlelo lokusebenza. Lo mhlangano wonke uthengiswa njengeyunithi ehlolwe ngokuphelele futhi eqinisekisiwe, inombolo eyodwa ye-serial kanye nemibhalo ehlobene nokuthola imininingwane yazo zonke izingxenye zomhlangano.

Ngoba umhlangano wakhelwa njengesixazululo esiphelele ezikhungweni ze-EMER3, unamathuba athuthukiswe kakhulu wokwehluleka kwezinga lokuthola (PFD). Kwezinye izimo, izinga lokuhluleka komhlangano lizobe lifinyelela kuma-50% ngaphansi kwenhlanganisela yezinto ezifanayo ze-valve ezithengwa ngawodwana futhi ziqoqelwe ngumsebenzisi wokugcina.
