Emerson akuyambitsa misonkhano ya SIL 3-certified valve

Emerson adayambitsa ma valve oyambilira omwe amakwaniritsa zofunikira pakupanga kwa Safety Integrity Level (SIL) 3 malinga ndi muyezo wa International Electrotechnical Commission wa IEC 61508.Izi FisherKudzipatula kwa digitoMayankho omaliza amakwaniritsa zosowa zamakasitomala pamakina otsekera pamakina ofunikira otetezedwa (SIS).

Popanda yankho ili, ogwiritsa ntchito ayenera kufotokoza zigawo zonse za valve, kugula chilichonse, ndi kuzisonkhanitsa kuti zikhale zogwira ntchito.Ngakhale masitepewa achitidwa moyenera, msonkhano wamtundu uwu sudzaperekabe phindu lonse la msonkhano wa Digital Isolation.

Kupanga valavu yotseka chitetezo ndi ntchito yovuta.Zomwe zimachitika bwino komanso zokhumudwitsa ziyenera kuyesedwa mosamala ndikumvetsetsa posankha zida za valve ndi actuator.Kuonjezera apo, kuphatikiza koyenera kwa solenoids, mabatani, kugwirizanitsa ndi zida zina zofunika kwambiri ziyenera kufotokozedwa ndikugwirizanitsa mosamala ndi valve yosankhidwa.Chilichonse mwa zigawozi chiyenera kugwira ntchito payekha komanso mogwirizana kuti zigwire ntchito.

Emerson amayankha izi ndi zina mwa kupereka makina opangidwa ndi Digital Isolation shutdown valve, opangidwira njira iliyonse.Zigawo zosiyanasiyana zimasankhidwa mwachindunji kuti zikwaniritse zofunikira zofunsira.Msonkhano wonsewo umagulitsidwa ngati gawo loyesedwa mokwanira komanso lovomerezeka, lomwe lili ndi nambala imodzi ya serial ndi zolembedwa zofananira zomwe zikufotokozera tsatanetsatane wa gawo lililonse la msonkhano.

Chifukwa msonkhanowu umamangidwa ngati yankho lathunthu m'maofesi a Emerson, uli ndi mwayi wokwera kwambiri wolephera pakufunika (PFD).Nthawi zina, kulephera kwa msonkhano kudzakhala 50% yochepa kusiyana ndi kuphatikiza kwa zigawo zofanana za valve zomwe zimagulidwa payekha ndikusonkhanitsidwa ndi wogwiritsa ntchito mapeto.
