U-Emerson wazisa iindibano zevalvu eziqinisekisiweyo ze-SIL 3

U-Emerson uye wazisa iindibano zevalvu zokuqala ezihlangabezana neemfuno zenkqubo yoyilo lweNqanaba leSidima soKhuseleko (SIL) 3 ngokomgangatho we-IEC 61508 weKomishoni ye-Electrotechnical yaMazwe ngaMazwe. Ezi FisherUkwahlulwa kweDijithaliIzisombululo zento yokugqibela zikhonza iimfuno zabathengi kwiivalvu zokuvala kwinkqubo yokhuseleko ebalulekileyo (SIS) izicelo.

Ngaphandle kwesi sisombululo, abasebenzisi kufuneka bachaze onke amacandelo evalvu, bathenge nganye, kwaye bawahlanganisele ukuba asebenze ngokupheleleyo. Nangona la manyathelo enziwe ngokuchanekileyo, olu hlobo lwendibano yesiko alusayi kubonelela zonke izibonelelo zeDigital Isolation assembly.

Ubunjineli bevalve yokuvalwa kokhuseleko ngumsebenzi onzima. Iimeko zenkqubo eqhelekileyo kunye nokuphazamiseka kufuneka zihlolwe ngononophelo kwaye ziqondwe xa ukhetha i-valve kunye ne-actuator components. Ukongezelela, ukudibanisa okufanelekileyo kwee-solenoids, izibiyeli, ukudityaniswa kunye nezinye izinto ezibaluleke kakhulu kufuneka zichazwe kwaye zihambelane ngokucophelela nevalve ekhethiweyo. Ngalinye kula macandelo kufuneka lisebenze ngokwalo kunye nangekonsathi ukuze lisebenze.

U-Emerson ulungisa le miba kunye neminye ngokubonelela ngobunjineli be-Digital Isolation yevalve yokuvala i-valve, eyilelwe inkqubo ethile. Amacandelo ahlukeneyo akhethwe ngokukodwa ukwanelisa iimfuno zesicelo. Indibano yonke ithengiswa njengeyunithi evavanyiweyo neqinisekisiweyo ngokupheleleyo, enenombolo yothotho enye kunye namaxwebhu anxulumeneyo achaza iinkcukacha zenxalenye nganye yendibano.

Ngenxa yokuba indibano yakhiwe njengesisombululo esipheleleyo kwizibonelelo ze-Emerson, iqhayisa ngokuphucuka kakhulu kwamathuba okusilela kwimfuno (PFD). Kwezinye iimeko, izinga lokungaphumeleli kwendibano liya kuba li-50% ngaphantsi kokuhlanganiswa kwezinto ezifanayo zevalve ezithengwe ngabanye kwaye zihlanganiswe ngumsebenzisi wokugqibela.
