Ukulinganisa ingcindezi eqondile kusekela ukusebenza kwethangi le-propylene okuqhubekayo ngokuvumela ukuvuza okusheshayo kanye nokutholakala kokucindezela ngokweqile, okubalulekile ekugcineni ukuphepha kwe-propylene yoketshezi. Ukulinganisa okunembile kuvimbela ukungcoliswa kwesigaba segesi, kusekela ukwenziwa ngcono kwebhalansi yesisindo, futhi kugwema isikhathi sokungasebenzi. Ukulinganiswa komshini wokudlulisa ingcindezi yezimboni kuqinisekisa ukunemba kwedivayisi ngokuhamba kwesikhathi, kuhlangabezana nezindinganiso eziqinile zokuthobela imithetho yezindawo eziyingozi.

Ukubuka Konke Kwenqubo Yezimboni
I-propylene yoketshezi igcinwa ekucindezelweni okuvame ukuba phakathi kwamabha angu-8-14, igcinwa emathangini avikelwe ukuze kuvinjelwe ukulahlekelwa ukuhwamuka. Uketshezi olucindezelwe luhanjiswa ngamapayipi aphezulu kuya ezitotshini zokusika zezimboni ukuze kucutshungulwe insimbi nengilazi. Ama-transmitter okucindezela ahlakaniphile—njenge-transmitter yokucindezela ehlakaniphile engu-3051 kanye nezinsimbi ezingaphakathi kwe-Lonnmeter—aqapha ingcindezi yethangi kanye nomugqa ngokuqhubekayo, enikeza amanani esikhathi sangempela ezinhlelweni zokulawula izitshalo.
Noma yikuphi ukuphambuka ekucindezelweni kwe-propylene kuthinta ngqo ikhwalithi yelangabi lesibani. Ukucindezela okuzinzile kuqinisekisa ukugeleza kwegesi kaphethiloli okulungile, okugcina isilinganiso se-oxygen/fuel esidingekayo ukuze kube nobubanzi obuhambisanayo be-kerf kanye nokushelela kobuso obusikiwe. Ucwaningo lubonisa ukuthi ukushintshashintsha kwengcindezi okungu-±5% kungandisa i-slag futhi kunciphise isivinini sokusika ngamaphesenti afinyelela ku-12 (Chaterjee, Welding Journal, 2017). Ukucindezela okungazinzile kuveza ukugeleza okungaguquki, okubangela ukushaya komlilo, ukushisa okungalingani, kanye nokuguguleka kwe-tip okusheshayo, ngaleyo ndlela kukhuphule izindleko zokusetshenziswa kanye nokugcinwa.
Impendulo eqondile eqondile evela kumthumeli wokucindezela okuku-inthanethi ukuze isetshenziswe ezimbonini isekela imisebenzi yokuphepha ezenzakalelayo, okuhlanganisa ukuvala ngokushesha uma kwenzeka ukucindezela ngokweqile noma ukuvuza. Ukulinganiswa komthumeli wokucindezela kwezimboni kubalulekile ukuze kulondolozwe lokhu kunemba okuphezulu ezindaweni zokuqapha ukucindezela kwethangi le-propylene ezidingakalayo.

Izinselele Ekulinganisweni Kokucindezela Okuqondile
Ukuqapha ingcindezi yethangi le-propylene ngesikhathi sangempela kubhekene nokushintshashintsha okusheshayo kwengcindezi kusuka emazingeni okuhoxiswa okuguquguqukayo. Izimo zesikhashana ngesikhathi sokulayisha noma ukukhishwa kudala ukungazinzile kwesignali, lapho ukuzulazula kokulinganisa kuvame ukwedlula ±0.25% FS ngesikhathi sokukhuphuka. I-propylene yoketshezi egqwalayo yonakalisa ama-diaphragm enzwa kanye ne-elekthronikhi, ifinyeza umjikelezo wokuphila wokusebenza futhi idinga ama-alloy noma ama-polymer amelana nokugqwala. Izinga lokushisa lishintsha kancane njenge-5°C lishintsha ubuningi boketshezi ngo-1.7%, okuthinta ngqo ukunemba kokulinganisa kanye nokuqina kokulinganisa kokudlulisela ingcindezi yezimboni. Izindawo eziyingozi zidinga ama-transmitter okucindezela angaphakathi angaqhumi, aphephile ngaphakathi ngenxa yokusha kwe-propylene; ukwehluleka ukuhambisana kungabangela ingozi enkulu. Ama-alamu angamanga avela ekukhuphukeni kwesignali noma ukuphazamiseka kukagesi kumise ukukhiqizwa ezindaweni ezingaphezu kuka-15% ezihloliwe, okubangela isikhathi sokungasebenzi kanye nokulahlekelwa yimpahla. Amadivayisi e-smart pressure sensor kanye nemiklamo ethuthukisiwe, njenge-3051 smart pressure transmitter noma i-online pressure transmitter yokusetshenziswa kwezimboni, kunciphisa ukulinganiswa ngesandla. Izixazululo ze-Lonnmeter inline pressure transmitter zihlanganisa ukuxilongwa okuphansi kokunakekelwa, okubikezelayo kwezixazululo zokugcina i-propylene yoketshezi olunamandla.
Izinzuzo Zokuhlanganisa Ama-Inline Pressure Transmitters
Ukuhlanganisa ama-inline pressure transmitters kwisitoreji se-propylene esiwuketshezi kunikeza isilinganiso esinembile nesiqhubekayo esinomthelela oqondile ekusebenzeni. Ukuxilongwa kwesikhathi sangempela kukhulisa isikhathi sokusebenza kwesitshalo: ukuvuza okusheshayo noma ukutholwa kokuphambuka kuvumela impendulo ngemizuzwana, kunciphisa kakhulu isikhathi sokungasebenzi. Ukunemba okuphezulu ezindaweni ezisezingeni eliphansi—ngokuvamile okudingekayo kwisitoreji sokuphepha se-propylene—kuqinisekisa ukuzinza kwenqubo, kugcina umehluko ungaphansi kuka-±0.1% wesikhathi.
Umklamo omncane wenza kube lula ukuthunyelwa ezindaweni ezigcwele amathangi lapho isikhala singaphansi kwama-60 mm, okubalulekile ekufakweni kabusha noma ukufakwa okuxineneyo. Ukuhlanganiswa nezinhlelo ze-PLC kanye ne-SCADA ngokusebenzisa amaphrothokholi edijithali (isb., i-HART, 4-20mA) kwenza kube lula ukuxwayisa ngokuzenzakalela: opharetha baziswa ngokushesha uma ingcindezi idlula imikhawulo ebekiwe ngaphambilini.
Isithumeli sokucindezela esiku-inthanethi esisetshenziswa ezimbonini sinciphisa ukuhlolwa ngesandla kanye nokuvezwa komqhubi ezindaweni eziyingozi. Ukufinyelela okuzenzakalelayo, okukude kokulinganisa kwenza kube lula ukuhamba komsebenzi wokulungisa, kusekela ukuhlela ukulinganiswa komshini wokucindezela wezimboni, futhi kunciphisa ingozi yokukhukhuleka okungabonakali. Lawa makhono ayisisekelo sokuqapha ukucindezeleka kwethangi le-propylene okuthembekile, kusekela kokubili ikhwalithi yenqubo kanye nokuhambisana.
