Kwizityalo zemichiza, ukulinganisa amanqanaba olwelo ngokuchanekileyo nangokuthembeka kubalulekile ukugcina imisebenzi ekhuselekileyo nesebenzayo.Esinye sezona zivamvo zenqanaba lolwelo lwe-telemetry ezisetyenziswa kakhulu yi-static pressure liquid level transmitter.Le ndlela ibala inqanaba lolwelo ngokulinganisa uxinzelelo lwe-static lwekholamu yolwelo kwinqanawa.Kweli nqaku, siza kuxoxa ngamanqaku aphambili okukhetha kunye neemeko zokusetyenziswa kwe-XDB502 ye-liquid level sensor kwizixhobo zekhemikhali.
Iimpawu kunye nezinto eziluncedo
I-sensor yenqanaba le-XDB502 ye-liquid level ineempawu ezininzi kunye neenzuzo ezenza ukuba zilungele uluhlu olubanzi lwezicelo kwizityalo zemichiza.Ezi ziquka:
Ukusetyenziswa kubushushu obuphezulu, uxinzelelo oluphezulu, i-viscosity ephezulu, kunye neendawo ezinobungozi kakhulu, okwenza ukuba zilungele uluhlu olubanzi lwezicelo.
Uluhlu olukhulu lokulinganisa oluguquguqukayo ngokwendawo, kwaye akukho mabala angaboniyo.
Ukuthembeka okuphezulu, ukuzinza, ubomi obude, kunye neendleko zokugcinwa okuphantsi.
Umlinganiselo ochanekileyo ophezulu, ngokuchaneka ukuya kuthi ga ku-+0.075% isikali esipheleleyo (fs) kwizidlulisi zomgangatho wolwelo olungenaxinzelelo olusuka kumazwe angaphandle kunye ne-+0.25% fs kwizidlulisi zomgangatho wolwelo lwesiqhelo lwasekhaya.
Ukuzixilonga ngobuchule kunye nemisebenzi yokuseta kude.
Iinketho ezahlukeneyo zokuphuma kweempawu, kubandakanywa iiprothokholi ezahlukeneyo zomgangatho we-4mA-20mA yeempawu zangoku, imiqondiso ye-pulse, kunye neempawu zonxibelelwano lwe-fieldbus.
Amanqaku okuKhetha
Xa ukhetha i-static pressure liquid level transmitter, la manqaku alandelayo kufuneka aqwalaselwe:
Ukuba uluhlu olulinganayo (uxinzelelo olwahlukileyo) lungaphantsi kwe-5KPa kwaye ubuninzi bomlinganiselo ophakathi butshintsha ngaphezu kwe-5% yexabiso loyilo, i-differential pressure level transmitter ayifanele isetyenziswe.
Ukutsha kolwelo, ugqabhuko-dubulo, ukutyhefa, ukudleka, i-viscosity, ubukho bamasuntswana axhonyiweyo, utyekelo lokuba ngumphunga, kunye notyekelo lokujiya kumaqondo obushushu akhoyo kufuneka kuqwalaselwe xa kukhethwa isidlulisi.
I-transmitter inokuyilwa kunye neeflange enye okanye ezimbini.Ukuhanjiswa kweflange kabini, ubude be-capillary kufuneka bulingane.
Ulwelo oluqhelene necrystallization, intlenga, i-viscosity ephezulu, i-coking, okanye i-polymerization, uhlobo lwe-diaphragm olwahlukileyo loxinzelelo lwenqanaba lokuhambisa ulwelo kunye nendlela yokutywina yokufakwa kufuneka kukhethwe.
Kwiimeko apho isigaba serhasi sinokujiya kwaye isigaba solwelo sinokuguquka sibe ngumphunga, kwaye isikhongozelo siphantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu, i-condenser, i-isolator, kunye nesikhongozeli sebhalansi kufuneka sifakwe xa kusetyenziswa isidluliseli somgangatho wolwelo oluqhelekileyo ngokwahlukileyo. umlinganiselo wenqanaba lolwelo.
Olona tshintsho luphezulu loxinzelelo lolwelo lufuna uguqulo loluhlu.Ngoko ke, umthumeli kufuneka abe noluhlu lwe-offset function, kwaye ixabiso le-offset kufuneka libe ubuncinane be-100% yomda ophezulu woluhlu.Xa ukhetha i-transmitter, i-offset kufuneka ithathelwe ingqalelo, ngakumbi xa ulinganisa i-high-density media.Ke ngoko, uluhlu lwe-transmitter kufuneka lukhethwe ngokusekelwe kwimeko ye-offset.
Imiqathango yokusetyenziswa
I-sensor yenqanaba le-XDB502 ineemeko ezininzi zokusetyenziswa ekufuneka ziqwalaselwe:
Ubushushu benkqubo: Olu hlobo lokuhambisa lusebenza ngokuhambisa uxinzelelo ngokuzalisa ulwelo oluvalwe ngaphakathi kwisixhobo.Ukuzaliswa okuqhelekileyo kwamanzi kubandakanya i-silicone ye-200, i-silicone ye-704, i-hydrocarboni e-chlorinated, imixube ye-glycerol kunye namanzi, phakathi kwabanye.I-liquid nganye yokuzalisa inomlinganiselo ofanelekileyo wokushisa, kwaye uhlobo lokuzaliswa kufuneka lukhethwe ngokusekelwe kwiimpawu zeekhemikhali zomgangatho olinganisiweyo kunye nokushisa kwenkqubo.Ke ngoko, xa ubushushu benkqubo bungaphezu kwe-200℃, ukusetyenziswa kwe-diaphragm-sealed transmitter kufuneka kuqwalaselwe ngononophelo.Ukuba kukho imfuneko, kufuneka kukhethwe isixokelelwano sokutywina esandisiweyo okanye isixhobo sokwandisa ubushushu, kwaye umenzi wothumelo kufuneka aqinisekise iinkcukacha.
Ubushushu be-Ambient: Ulwelo lokuzalisa kufuneka luzaliswe kubushushu obufanelekileyo be-ambient.I-capillary kufuneka igcinwe ihambelana neqondo lokushisa lokuzalisa ulwelo.Njengoko i-epoxyethane kwizixhobo ze-EOEG ezinokutsha ziqhelene ne-polymerization, i-diaphragm-sealed differential pressure fluid level transmitter kufuneka isetyenziswe ukulinganisa inqanaba le-epoxyethane medium.Njengoko izisombululo zekhabhoniti ziqhelene necrystallization, i-diaphragm-sealed differential pressure fluid level transmitter enenkqubo yokutywina yofakelo kufuneka isetyenziswe, kunye nendawo yokufaka egungxulwayo ngodonga lwangaphakathi lwesixhobo.Idayamitha yangaphandle yofakelo kunye nobude bumiselwa ngokusekelwe kwiinkcukacha zesixhobo.Kwisixhobo esinobushushu obungama-250℃ okanye ngaphezulu, kufuneka kusetyenziswe umbhobho oqhelekileyo woxinzelelo.
Ukuqukumbela
Ukuqukumbela, i-sensor yenqanaba le-XDB502 yenqanaba lolwelo lukhetho oluthembekileyo noluchanekileyo lokulinganisa amanqanaba olwelo kwizityalo zemichiza.Ineengenelo ezininzi, kubandakanya uluhlu olubanzi, ukuchaneka okuphezulu, iinketho ezahlukeneyo zokuphuma kwemiqondiso, kunye nokuzixilonga ngobukrelekrele.Xa ukhetha isidluliseli, iimpawu zolwelo, njengokutsha, ukudubula, ubutyhefu, ukubola, kunye ne-viscosity, kufuneka ziqwalaselwe.Ukongezelela, iimeko zokusetyenziswa ezifana nobushushu benkqubo kunye nobushushu be-ambient kufuneka zithathelwe ingqalelo ukuze kuqinisekiswe imilinganiselo echanekileyo nethembekileyo.
