Emerson yatangije uburyo bwo guteranya valves zifite icyemezo cya SIL 3

Emerson yashyizeho uburyo bwa mbere bwo guteranya imiyoboro y'amashanyarazi buhuye n'ibisabwa mu buryo bwo gushushanya urwego rw'ubuziranenge bw'umutekano (SIL) 3 hakurikijwe ibipimo ngenderwaho bya IEC 61508 bya Komisiyo Mpuzamahanga y'Ubuhanga mu by'Ingufu. Aba FisherGutandukanya abantu hakoreshejwe ikoranabuhangaIbisubizo bya nyuma by'ibikoresho bifasha abakiriya gukenera valve zo kuzimya mu buryo bw'ingenzi bwo kwirinda (SIS).

Hatabayeho ubu buryo, abakoresha bagomba kugaragaza ibice byose bya valve, bagashaka buri kimwe, hanyuma bakagiteranya kikakigira ikintu cyose gikora. Nubwo ibi bikorwa neza, ubwo bwoko bw'iteranya ryihariye ntibuzatanga inyungu zose zo guteranya kwa Digital Isolation.

Gutunganya valve yo kuzimya umutekano ni akazi katoroshye. Imiterere isanzwe n'ihindagurika ry'imikorere igomba gusuzumwa neza no gusobanuka mu gihe cyo guhitamo ibice bya valve na actuator. Byongeye kandi, guhuza neza solenoids, brackets, couplings n'ibindi bikoresho by'ingenzi bigomba kugaragazwa no guhuzwa neza na valve yatoranijwe. Buri gice muri ibi bice kigomba gukora ukwacyo kandi gihujwe kugira ngo gikore neza.

Emerson akemura ibi bibazo n'ibindi atanga uburyo bwo gufunga valve ya digitale, yagenewe buri gikorwa runaka. Ibice bitandukanye byatoranijwe by'umwihariko kugira ngo byuzuze ibisabwa mu ikoreshwa. Uburyo bwose bugurishwa nk'igikoresho cyapimwe kandi cyemewe, gifite inomero imwe y'uruhererekane n'inyandiko zijyanye nacyo zigaragaza ibisobanuro bya buri gice cy'uburyo.

Kubera ko iyi nteguro yubatswe nk'igisubizo cyuzuye mu bigo bya Emerson, ifite amahirwe menshi yo gutsindwa ku gipimo cya PFD. Mu bihe bimwe na bimwe, igipimo cyo gutsindwa kw'iyi nteguro kizaba kiri munsi ya 50% ugereranyije n'uruvange rw'ibice bimwe bya valve byaguzwe ukwabyo kandi bigateranywa n'umukoresha wa nyuma.
