Ibhokisi yokuTshintshela yoMda: IsiKhokelo esiBanzi
Kwiinkqubo zale mihla zemizi-mveliso ezizisebenzelayo kunye nolawulo lwevalvu, ukuqinisekisa ukuba ukubekwa esweni okuchanekileyo kwendawo yevalvu kubalulekile. Aibhokisi yokutshintsha umdaidlala indima ebalulekileyo kule nkqubo ngokubonelela ngengxelo ethembekileyo kubaqhubi kunye neenkqubo zolawulo. Enoba kukwimibhobho yeoli nerhasi, kumaziko okucoca amanzi, okanye kwimizi-mveliso yemichiza, esi sixhobo siqinisekisa ukuba ukusebenza kwevalvu kukhuselekile, kuchanekile kwaye kuyalandeleka.
Eli nqaku linika inkcazo eneenkcukacha malunga nokuba yintoni ibhokisi yokutshintsha umda, isebenza njani, iinxalenye zayo eziphambili, iindidi ezahlukeneyo, kunye nezicelo kumashishini ahlukeneyo. Ekugqibeleni, uya kuba nokuqonda ngokucacileyo ukuba kutheni esi sixhobo siyimfuneko kulawulo lwenkqubo.
Yintoni iBhokisi yokuTshintshela yoMda?
Ibhokisi yokutshintsha umda sisixhobo esidibeneyo esifakwe phezulu kwee-actuator okanye iivalve. Umsebenzi wayo ophambili kukubonisa ukuba i-valve ikwindawo evulekileyo okanye evaliweyo. Iguqula intshukumo yomatshini yesikhondo sevalve okanye i-actuator shaft ibe ngumqondiso wombane onokuthunyelwa kwinkqubo yolawulo esasazwayo (DCS), isilawuli sengqiqo ecwangcisiweyo (PLC), okanye izikhombisi ezibonakalayo zabasebenzi bezityalo.
Ngamagama alula, isebenza "njengamehlo" enkqubo yevalve. Ngelixa i-actuator ihambisa ivalve, ibhokisi yokutshintsha umda iqinisekisa ukuba abaqhubi bayazi kakuhle apho ivalve ibekwe khona.
IiNjongo eziPhambili
- Ingxelo yeNdawo yeValve– Ibonelela ngemiqondiso yombane kumagumbi olawulo malunga nokuba ivalve ivuliwe okanye ivaliwe.
- Ingqinisekiso yoKhuseleko-Ithintela imisebenzi engalunganga enokubangela ukuvuza, ukuchitheka, okanye iingozi.
- Ukudibanisa okuzenzekelayo-Ivumela uxhulumaniso kunye nee-PLC kunye neenkqubo ze-SCADA zolawulo lwenkqubo oluzenzekelayo.
- Isalathiso esibonakalayo-Iibhokisi ezininzi zibandakanya izalathisi zoomatshini (umzekelo, iintolo ezibomvu/ eziluhlaza okanye iidomes) ukuze kube lula ukubeka iliso kwisiza.
Isebenza Njani Ibhokisi Yokutshintsha Umda?
Umgaqo osebenzayo webhokisi yokutshintsha umda ulula ngokuthe ngqo, kodwa ukuthembeka kwayo kuyenza ibaluleke kakhulu.
- Intshukumo yoomatshini– Xa i-actuator ivula okanye ivala ivalve, i-shaft okanye i-stem ijikeleza okanye ihamba ngokulandelelana.
- ICam Mechanism-Ngaphakathi kwebhokisi yokutshintsha umda, ikhamera efakwe kwi-shaft ijikeleza ngokufanelekileyo.
- Tshintsha Ukuqalisa-Ikhamera ibandakanyeka kunye neeswitshi ezincinci, izinzwa ezisondele, okanye izinzwa zemagneti ngaphakathi kwebhokisi.
- Ugqithiso loMqondiso– Nje ukuba isebenze, ezi zitshintshi zithumela isignali yombane ukubonisa indawo yevalve (evulekileyo/evaliweyo okanye ephakathi).
- Ingxelo kwiNkqubo yoLawulo-Isiginali idluliselwa kwiipaneli zokulawula, i-SCADA, okanye imiboniso yendawo.
Umzekelo Owenziwe Lula
- Ivalve ivuleke ngokupheleleyo → Ikhamera ixhokonxa “vula” iswitshi → Umqondiso oluhlaza uthunyelwe.
- Ivalve ivalwe ngokupheleleyo → Ikhamera ixhokonxa iswitshi “evaliweyo” → Umqondiso obomvu uthunyelwe.
- Ivalve kutshintsho → Akukho phawu luqinisekileyo, okanye kwiimodeli eziphambili, ingxelo ye-analog ebonisa indawo ngqo.
