Isishwankathelo seNkqubo yoShishino
Ipropylene yolwelo igcinwa kwiingcinezelo eziqhelekileyo eziphakathi kwe-8-14 bar, igcinwa kwiitanki ezigqunyiweyo ukuthintela ukulahleka komphunga. Ulwelo oluxinzelelweyo luhanjiswa ngemibhobho ephezulu ukuya kwiitotshi zokusika zoshishino ukuze kucutshungulwe intsimbi neglasi. Iitransmitter zoxinzelelo ezikrelekrele—ezifana ne-3051 smart pressure transmitter kunye nezixhobo ze-Lonnmeter inline—zijonga i-tank kunye noxinzelelo lomgca rhoqo, zibonelela ngexabiso lexesha langempela kwiinkqubo zolawulo lwezityalo.
Nakuphi na ukuphambuka kuxinzelelo lwepropylene kuchaphazela ngokuthe ngqo umgangatho welangatye letotshi. Uxinzelelo oluzinzileyo luqinisekisa ukuhamba kwegesi yepetroli ngokuchanekileyo, okugcina umlinganiselo weoksijini/ipetroli ofunekayo ukuze ububanzi be-kerf buhlale bufana kwaye ubuso bube bushelelezi. Uphando lubonisa ukuba ukuguquguquka koxinzelelo lwe-±5% kunokunyusa i-slag kwaye kunciphise isantya sokusika ukuya kuthi ga kwi-12% (Chaterjee, Welding Journal, 2017). Uxinzelelo olungazinzileyo luvelisa ukuhamba okungahambelaniyo, okubangela ukudumba komlilo, ubushushu obungalinganiyo, kunye nokuguguleka kwencam ngokukhawuleza, ngaloo ndlela kunyusa iindleko zokusetyenziswa kunye nokugcinwa.
Impendulo ethe ngqo emgceni evela kwi-transmitter yoxinzelelo ekwi-intanethi yokusetyenziswa kwimizi-mveliso ixhasa imisebenzi yokhuseleko ezenzekelayo, kubandakanya ukuvala ngokukhawuleza ukuba kukho uxinzelelo olugqithisileyo okanye ukuvuza. Ukulinganiswa kwe-transmitter yoxinzelelo kwimizi-mveliso kubalulekile ukugcina olu lwazi luphezulu kwiindawo zokujonga uxinzelelo lwetanki yepropylene ezifuna amandla.

Imingeni ekulinganiseni uxinzelelo oluphakathi
Ukujonga uxinzelelo lwetanki yepropylene ngexesha langempela kujongana nokutshintshatshintsha koxinzelelo oluvela kumazinga okurhoxisa aguquguqukayo. Iimeko zexesha elifutshane ngexesha lokulayisha okanye ukukhupha zenza ukungazinzi kwesignali, kunye nokuhamba kokulinganisa rhoqo kudlula i-±0.25% FS ngexesha lokunyuka. Ipropylene yolwelo ebolayo yonakalisa ii-diaphragms zesensor kunye ne-elektroniki, inciphisa umjikelo wobomi bokusebenza kwaye ifuna ii-alloys okanye ii-polymers ezimelana nokugqwala. Ubushushu butshintsha kancinci njenge-5°C butshintsha uxinano lolwelo nge-1.7%, buchaphazela ngokuthe ngqo ukuchaneka kokulinganisa kunye nozinzo lokulinganisa i-transmitter yoxinzelelo lwemizi-mveliso. Iindawo ezinobungozi zifuna ii-transmitter zoxinzelelo ezingaphakathi ezikhuselekileyo, ezikhuselekileyo ngokwangaphakathi ngenxa yokutsha kwepropylene; ukungaphumeleli kokuthobela kunokubangela umngcipheko omkhulu. Ii-alamu zobuxoki ezivela ekushukumeni kwesignali okanye ukuphazamiseka kombane ziye zamisa imveliso kwiindawo ezingaphezulu kwe-15% zezibonelelo ezihlolisisiweyo, ezibangela ukungasebenzi kunye nokulahleka kwempahla. Izixhobo ze-sensor yoxinzelelo ezikrelekrele kunye noyilo oluphambili, olufana ne-3051 smart pressure transmitter okanye i-online pressure transmitter yokusetyenziswa kwimizi-mveliso, zinciphisa ukulinganiswa ngesandla. Izisombululo ze-Lonnmeter inline pressure transmitter zidibanisa ukuxilongwa okuncinci, okuxelwa kwangaphambili kwezisombululo zokugcina i-propylene yolwelo olunamandla.
Iingenelo zokudibanisa ii-Inline Pressure Transmitters
Ukudibanisa ii-inline pressure transmitters kwindawo yokugcina i-propylene engamanzi kunika umlinganiselo ochanekileyo noqhubekayo onefuthe ngqo kwimisebenzi. Ukuxilongwa ngexesha langempela kwandisa ixesha lokusebenza kwesityalo: ukuvuza okukhawulezayo okanye ukufunyanwa kokuphambuka kuvumela impendulo kwimizuzwana, kunciphisa kakhulu ixesha lokungasebenzi. Ukuchaneka okuphezulu kwiindawo ezisezantsi-ezifunekayo rhoqo kwi-propylene ekhuselekileyo-kuqinisekisa uzinzo lwenkqubo, kugcina umahluko ungaphantsi kwe-±0.1% yesithuba.
Uyilo oluncinci luvumela ukuthunyelwa kwiindawo zokungenisa iitanki ezixineneyo apho indawo ingaphantsi kwama-60 mm, nto leyo ebalulekileyo ekufakelweni kwezinto ezintsha okanye ezixineneyo. Ukudibanisa neenkqubo ze-PLC kunye ne-SCADA ngokusebenzisa iiprotokholi zedijithali (umz., i-HART, i-4-20mA) kwenza kube lula ukulumkisa ngokuzenzekelayo: abaqhubi baziswa ngoko nangoko ukuba uxinzelelo ludlula imida ebekiweyo.
Isithumeli soxinzelelo esikwi-intanethi esisetyenziselwa imboni sinciphisa ukujonga ngesandla kunye nokuvezwa komqhubi kwiindawo ezinobungozi. Ukufikelela ngokuzenzekelayo, okukude kwimilinganiselo kwenza kube lula ukugcinwa komsebenzi, kuxhasa ucwangciso lokulinganisa isithumeli soxinzelelo lwemboni, kwaye kunciphisa umngcipheko wokushukuma okungabonakaliyo. Ezi zakhono zibalulekile ekujongeni uxinzelelo lwetanki yepropylene ethembekileyo, zixhasa umgangatho wenkqubo kunye nokuthobela.
