Emkhakheni wokushisaukulinganisa amandla, amamitha okushisa kagesi kanye namamitha okushisa e-ultrasonic avelele njengamadivayisi amabili adumile futhi athuthukile kwezobuchwepheshe. Naphezu kwenhloso yawo efanayo yokulinganisa ngokunembile ukusetshenziswa kokushisa, abonisa umehluko omkhulu ezimisweni zawo zokusebenza, izici zokusebenza, kanye nezimo zokusetshenziswa. Ukuqonda lokhu kwahlukana kubalulekile ekukhetheni ikhambi lokulinganisa ukushisa elifanele kakhulu lezinhlelo ezahlukene zokushisa nokupholisa.
1. Izimiso Zokusebenza
1.1 Amamitha Okushisa Kagesi Kagesi
Amamitha okushisa e-electromagnetic asebenza ngokusekelwe emthethweni kaFaraday wokungeniswa kwe-electromagnetic. Ngaphakathi kwemitha, kukhona insimu yamagnetic ekhiqizwa ngamakhoyili. Lapho indawo yokushisa eqhubayo, njengamanzi, igeleza ngepayipi lokulinganisa lemitha iqonde ngqo kule nsimu yamagnetic, kudalwa amandla e-electromotive. Ngokomthetho kaFaraday, ubukhulu bamandla e-electromotive buhambisana ngqo nejubane lokugeleza kwe-medium kanye namandla ensimu yamagnetic. Ngokulinganisa le voltage ebangelwayo,izinga lokugelezayendlela yokushisa inganqunywa. Ngokuhambisana nokulinganisa umehluko wokushisa phakathi kwamapayipi okuhambisa kanye nawokubuyisela, ukusetshenziswa kokushisa kungabalwa ngokunembile. Lesi simiso senza amamitha okushisa kagesi abe bucayi kakhulu ekugelezeni koketshezi oluqhubayo, futhi anganikeza imiphumela yokulinganisa ethembekile inqobo nje uma uketshezi lugcina ugesi uqhuba.
1.2 I-UltrasonicAmamitha Okushisa
Ngakolunye uhlangothi, amamitha okushisa e-Ultrasonic asebenzisa isimiso sokusabalala kwe-ultrasonic emanzini. Aqukethe ama-transducer e-ultrasonic akhipha futhi amukele amagagasi e-ultrasonic. Kunezindlela ezimbili eziyinhloko zokulinganisa ukugeleza: indlela yokuhamba - isikhathi kanye nendlela ye-Doppler. Endleleni yokuhamba - isikhathi, amagagasi e-ultrasonic athunyelwa phezulu naphansi ngokusebenzisa indawo egelezayo. Umehluko esikhathini sokusabalala kwamagagasi e-ultrasonic ahamba eziqondisweni eziphezulu naphansi uyalinganiswa. Lo mehluko wesikhathi uhlobene nejubane lokugeleza kwendawo. Njengoba indawo egeleza, igagasi le-ultrasonic elihamba phansi liyasheshiswa, kuyilapho elihamba phezulu lincishiswa. Ngokubala lo mehluko wesikhathi nokusebenzisa amafomula afanele, izinga lokugeleza lingatholakala. Indlela ye-Doppler, esebenza kakhulu emanzini anezinhlayiya ezimisiwe noma amabhamuza, ilinganisa ukushintsha kwemvamisa kwamagagasi e-ultrasonic abonakala kulezi zinhlayiya ezihambayo ukuze kutholakaleijubane lokugeleza. Njengoba kunjalo ngamamitha okushisa kagesi, amamitha okushisa e-ultrasonic nawo alinganisa umehluko wokushisa phakathi kwamapayipi okuhambisa kanye nawokubuyisela ukuze abale ukusetshenziswa kokushisa.
2. Ukunemba Nokuzwela Kokulinganisa
2.1 Amamitha Okushisa Kagesi Kagesi
Amamitha okushisa e-electromagnetic ngokuvamile anikeza ukunemba okuphezulu kanye nokuzinza, ikakhulukazi koketshezi oluhlanzekile noluhambisa umoya. Ukunemba kwawo akuthinteki kakhulu yizici ezifana nokuxinana koketshezi kanye nobuningi, inqobo nje uma uketshezi luhlala luhambisa umoya. Angafinyelela izinga lokunemba lika-±0.5% kuya ku-±1% ngaphansi kwezimo zokusebenza ezijwayelekile. Kodwa-ke, uma uketshezi luqukethe inani elikhulu lezinto ezingahambisa umoya, njengebhamuza lomoya noma izinhlayiya ezingezona ezihambisa umoya, kungaphazamisa insimu yamagnetic futhi kunciphise ukunemba kokulinganisa.
2.2 Amamitha Okushisa E-Ultrasonic
Ukunemba kwamamitha okushisa e-ultrasonic kuncike ezintweni ezahlukahlukene, okuhlanganisa ikhwalithi yama-transducer e-ultrasonic, ikhwalithi yokufaka, kanye nezici zoketshezi olulinganisiwe. Ezimweni ezifanele, ngoketshezi oluhlanzekile nokufakwa okufanele, amamitha okushisa e-ultrasonic asebenzisa indlela ye-transit-time angafinyelela ukunemba okucishe kube ngu-±1% kuya ku-±2%. Kodwa-ke, ukuba khona kwezinto eziqinile ezilengisiwe, isikali, noma amabhamuza omoya oketshezini kungaphazamisa ukusabalala kwamagagasi e-ultrasonic, okuholela emaphutheni okulinganisa. Amamitha okushisa e-ultrasonic ohlobo lwe-Doppler, afaneleka kakhulu koketshezi olungcolile, ngokuvamile anokunemba okuphansi uma kuqhathaniswa nohlobo lwe-transit-time, ngokuvamile azungeze u-±2% kuya ku-±5%.
3. Izimo Zokusetshenziswa
3.1 I-ElectromagneticAmamitha Okushisa
Amamitha okushisa kagesi afaneleka kahle ekusetshenzisweni lapho indawo yokushisa ihlanzekile futhi ihambisa umoya, njengasezinhlelweni zokushisa ezihlanganisiwe ezinamanzi ahlanziwe, izinhlelo zokushisa zesakhiwo zesimanje, kanye nezinqubo zezimboni ezinamanzi okuhambisa umoya. Azinconywa ukuthi zisetshenziswe nama-fluid angahambisani nomoya noma ama-fluid anokuqukethwe okuphezulu kokungcola okungahambisani nomoya, njengoba lokhu kungabangela ukwehluleka kokulinganisa. Ngaphezu kwalokho, ngenxa yesakhiwo sawo, amamitha okushisa kagesi adinga ubude obuthile bamapayipi aqondile ngaphambi nangemva kokufakwa ukuqinisekisa izimo zokugeleza ezizinzile, okungase kunciphise ukusetshenziswa kwawo ezindaweni ezithile ezilinganiselwe.
3.2 Amamitha Okushisa E-Ultrasonic
Amamitha okushisa e-Ultrasonic aguquguquka kakhulu ngokwezimo zokusetshenziswa. Uhlobo lwesikhathi sokuthutha lufanelekela uketshezi oluhlanzekile futhi luvame ukusetshenziswa ezinhlelweni zokushisa zokuhlala, amanethiwekhi okushisa wesifunda, kanye nezinhlelo zokuphakelwa kwamanzi. Amamitha okushisa e-Ultrasonic ohlobo lwe-Doppler angaphatha uketshezi olunezinhlayiya ezilengayo noma amabhamuza, okwenza asebenze ezinqubweni zezimboni lapho uketshezi lungase luqukathe ukungcola, njengezitshalo zokuhlanza amanzi amdaka noma ezinye izinqubo zokukhiqiza ngoketshezi olungcolile. Ngaphezu kwalokho, amamitha okushisa e-Ultrasonic awadingi ubude bepayipi obuqondile njengobude bamamitha okushisa e-electromagnetic, okwenza kube ukukhetha okulula kakhulu kokufakwa ezindaweni ezixineneyo.
4. Ukugcinwa Nokuqina
4.1 I-ElectromagneticAmamitha Okushisa
Amamitha okushisa kagesi ngokuvamile anesakhiwo sangaphakathi esilula ngaphandle kwezingxenye ezihambayo, okunciphisa ingozi yokuguguleka nokuguga komshini. Kodwa-ke, ithubhu yokulinganisa ingase ibe ngaphansi kokugqwala nokukhula ngokuhamba kwesikhathi, ikakhulukazi lapho ibhekene noketshezi oluqukethe izinto ezigqwalisayo noma amazinga aphezulu amaminerali. Ukuhlolwa njalo nokuhlanzwa kwethubhu yokulinganisa kuyadingeka ukuze kulondolozwe ukunemba kokulinganisa. Ngaphezu kwalokho, amakhoyili kagesi kanye nama-electrode kudingeka avikelwe ekuphazamisekeni kukagesi kanye nomonakalo ongokwenyama.
4.2 I-UltrasonicAmamitha Okushisa
Amamitha okushisa e-Ultrasonic nawo awanazo izingxenye ezihambayo, okufaka isandla ekuthembekeni kwawo kwesikhathi eside. Ukukhathazeka okuyinhloko kokugcinwa kwamamitha okushisa e-ultrasonic ukusebenza kwama-transducer e-ultrasonic. Ngokuhamba kwesikhathi, ama-transducer angase anciphe ngenxa yezici ezifana nokushintshashintsha kwezinga lokushisa, ukugqwala kwamakhemikhali, noma ukudlidliza komshini. Ukulinganiswa njalo nokuhlolwa kwama-transducer kuyadingeka ukuqinisekisa ukulinganiswa okunembile. Kodwa-ke, uma kuqhathaniswa namamitha okushisa e-electromagnetic, amamitha okushisa e-ultrasonic ngokuvamile awathinteki kakhulu ukugqwala koketshezi kanye nokukhula, okwenza ahlale isikhathi eside kwezinye izindawo ezinoketshezi olunzima.
Ekuphetheni, amamitha okushisa kagesi kanye namamitha okushisa e-ultrasonic ngalinye linezinzuzo kanye nemikhawulo yalo. Amamitha okushisa e-electromagnetic ahamba phambili ekulinganiseni uketshezi oluhlanzekile, oluqhuba ngokunemba okuphezulu, kuyilapho amamitha okushisa e-ultrasonic enikeza ukuguquguquka okukhulu ezimweni zokusetshenziswa futhi avumelana nezimo ezahlukahlukene zoketshezi. Lapho ukhetha phakathi kwalokhu okubili, izici ezifana nohlobo lwendawo yokushisa, ukunemba kokulinganisa okudingekayo, isikhala sokufaka, kanye nezidingo zokulungisa kufanele kucatshangelwe ngokucophelela ukuqinisekisa ukusebenza kahle kokushisa -uhlelo lokulinganisa.
