I-Guided Wave Radar (GWR) iyithuluzi lokulinganisa izinga lokubonisa elisekelwe ku-microwave elibonakala ngokusebenzisa kwayo i-probe yensimbi (i-waveguide) ukuqondisa ukusabalala kwesignali ye-microwave. Ivumela ukulinganisa okunembile amazinga oketshezi, ama-interface, noma amavolumu emidiya efana noketshezi, izinhlayiya eziqinile, noma ama-slurries. Ngokungafani namamitha angathintani ne-radar, amasignali e-microwave e-GWR awasabalali ngokukhululeka emoyeni kodwa ahamba ngendlela ehambisana ne-probe, enikeza izinzuzo ezihlukile ezimweni zokusebenza eziyinkimbinkimbi. Ngezansi isingeniso esinemininingwane esimboza isimiso sayo sokusebenza, izingxenye eziyinhloko, izici ezibalulekile, izimo zohlelo lokusebenza, kanye nemikhawulo.
I. Isimiso Sokusebenza
I-Guided Wave Radar ikhiqiza amasignali e-microwave asebenza ngesivinini esiphezulu (ngokuvamile angu-6GHz noma angu-26GHz) nge-transmitter module. Lawa masignali aqondiswa ngama-probe ensimbi akhethekile (isb., amakhebula ensimbi, izinduku eziqinile, amakhebula e-coaxial) ebusweni be-medium. Lapho amasignali e-microwave ehlangana ne-interface phakathi kwe-medium nomoya, ingxenye yesignali iyaboniswa bese ibuyela emuva nge-probe iye kwi-module eyamukelayo. Ithuluzi libala ukuphakama kwezinga ngokulinganisa umehluko wesikhathi (noma umehluko wemvamisa) phakathi kokudluliselwa kwesignali nokubonakaliswa, kuhlanganiswe nesivinini sokusabalala kwama-microwave ku-medium.
- Ifomula Eyinhloko: Ukuphakama kwezinga H=2v×t, lapho u-v kuyijubane lokusabalala kwama-microwave ku-probe, kanti u-t isikhathi sokubuya nokubuya sesiginali.
- Ukugxila Kwesignali: I-probe igcina amandla e-microwave endaweni elinganiselwe, igwema inkinga yokuhlukana kwezibonakaliso ze-radar ezingathintani ezisakazeka emoyeni, okuholela ezimpawini ezikhanyisiwe eziqinile nezizinzile.
II. Izingxenye Eziyinhloko
I-Guided Wave Radar inesakhiwo esincane kakhulu, esakhiwe kakhulu yizingxenye ezilandelayo:
- Iyunithi Ye-elekthronikhi: Inesibopho sokukhiqiza, ukudlulisa, ukwamukela, nokucubungula amasignali e-microwave. Ifaka i-microprocessor eyakhelwe ngaphakathi yokubala idatha kanye nokukhipha (isb., amasignali angu-4-20mA, HART, RS485).
- I-Probe (Umhlahlandlela Wamagagasi): “Isiteshi sokudlulisa” samasignali e-microwave, anezinhlobo ezivamile ezifaka:
- Ama-Rigid Rod Probes: Afanelekela uketshezi olune-viscosity ephansi kanye nezimo ezingadingi ukudlidliza, anikeza ukumelana okunamandla kokudlidliza.
- Ama-Probe Ekhebula Lensimbi: Alungele amathangi ajulile, imidiya ene-viscosity ephezulu, noma lawo aqukethe izinto eziqinile ezilengayo, okunikeza ukuguquguquka okuphezulu.
- Ama-Coaxial Probes: Amasignali ahamba phakathi kwama-conductor angaphakathi nangaphandle, afanelekela imidiya engaguquki ye-dielectric (isb., uwoyela okhanyayo, amagesi ancibilikisiwe) anekhono elithuthukisiwe lokulwa nokuphazamiseka.
- I-Flange/Interface Yokufaka: Ivikela ithuluzi phezulu kwethangi, ngezinto ezikhethiwe ngokusekelwe ekuboleni okuphakathi (isb., insimbi engagqwali engu-316L, i-Hastelloy).
III. Izici Eziyinhloko
1. Amandla Aqinile Okuvimbela Ukuphazamiseka Kwezimo Eziyinkimbinkimbi
- Izimpawu ze-microwave zihamba nge-probe, zinciphisa umthelela wezici zemvelo ezifana nomusi, uthuli, igwebu, noma inkungu. Zihlala zizinzile ngisho nasezindaweni ezinegwebu eliphezulu (isb., amathangi okubilisa ubhiya) noma ngaphansi kokushukunyiswa okukhulu.
- Azivikeleki ekuphazamisekeni okuvela ezakhiweni zangaphakathi zethangi (isb., iziqhumane, ama-baffle), njengoba izimpawu zisakazeka eduze kweprobe, zigwema ukuzwakala okungamanga okuvamile kwi-radar engathintani.
2. Ukunemba Okuphezulu Nokuzinza Kokulinganisa
- Ukunemba kokulinganisa kuvame ukusuka ku-±0.05%FS kuya ku-±0.1%FS, ngamaphutha okuphindaphinda aphansi njengo-±0.02%FS, okwenza kube ngcono kunamanye amamodeli e-radar angathintani.
- Amandla esignali yokuzindla ancike kakhulu ekuthinteni phakathi kweprobe kanye nendawo, okwenza ifaneleke kakhulu kwimidiya engaguquki ye-dielectric (isb., uphethiloli, igesi encibilikisiwe).
3. Ukuzivumelanisa Nezimo Ezihlukahlukene Zemidiya Nezindawo Ezibucayi
- Ukuhambisana Okumaphakathi: Iyakwazi ukulinganisa uketshezi (kufaka phakathi i-viscosity ephezulu, i-crystallizing media efana nesiraphu kanye ne-caustic soda), izinhlayiya eziqinile (isb., ama-pellet epulasitiki, impuphu yamalahle), ama-slurry (isb., udaka, ijusi yezithelo), kanye ne-interface (isb., i-interface yamafutha namanzi).
- Ukubekezelelana Kwemvelo: Imelana namazinga okushisa aphezulu (-50℃ kuya ku-400℃), ukucindezela okuphezulu (kufika ku-40MPa), kanye nezindawo ezigqwala kakhulu, ifanelekela ama-reactor amakhemikhali, amathangi okugcina anomfutho ophezulu, njll.
4. Ukufakwa Okuguquguqukayo Kwezindawo Ezivalekile
- Ama-probe angafakwa emathangini amancane, emikhunjini engalingani, noma ezitsheni ezinezithiyo zangaphakathi, ezingadingi isikhala esivulekile phezulu. Afaneleka kakhulu kumaphrojekthi okulungisa kabusha noma ezindaweni ezincane.
IV. Izimo Zokusetshenziswa
I-Guided Wave Radar isetshenziswa kabanzi kulezi zinsimu ezilandelayo ngenxa yokusebenza kwayo okulwa nokuphazamiseka kanye nokunemba okuphezulu:
- Imboni Yamakhemikhali: Ukulinganiswa kwezinga kuma-reactor, amathangi okugcina anomfutho ophezulu/ophansi, kanye nokutholwa kokuxhumana kwamafutha namanzi.
- Uphethiloli kanye ne-Petrochemical: Ukulinganiswa kwezinga emathangini kaphethiloli ongahluziwe, amathangi kaphethiloli alula (uphethiloli, udizili), kanye namathangi okugcina igesi encibilikisiwe.
- Ukudla Neziphuzo: Ukulinganiswa kwezinga emathangini okubilisa anegwebu eliphezulu (isb., ubhiya, iyogathi), amathangi esiraphu, kanye nama-slurry ejusi yezithelo (ngezinto zokuhlola ezisezingeni lokudla).
- Ukwelashwa Kwamanzi: Ukulinganiswa kwezinga emathangini okuhlanza indle kanye namachibi okudonsa amanzi, ukugwema ukuphazamiseka kwegwebu.
- Imboni Yamandla: Ukulinganiswa kwezinga ezitsheni zamalahle ezisebenzisa i-powder kanye nezitsha zomlotha, kanye nokuqapha izinga lebhoyila lokushisa eliphezulu.
V. Ukulinganiselwa
- Izidingo Zokunakekelwa Kokulinganisa Ukuthintana: Ama-probe athintana ngqo nendawo, avame ukungcola noma ukuvaleka ngenxa yokuxinana, okudinga ukuhlanzwa njalo. Imidiya egqwala kakhulu ingabangela ukuguguleka kwe-probe, okudinga izinto ezikhethekile (ukwandisa izindleko).
- Ibanga Lokulinganisa Elilinganiselwe: Ibanga eliphezulu linqunywa ubude be-probe, ngamamodeli avamile asukela ku-0.3m kuya ku-30m, angafaneleki emathangini amakhulu kakhulu (iradar engathintani ingamboza kufikela ku-100m).
- Imikhawulo Ekusetshenzisweni Kwenhlanzeko: Ezimweni zokudla, zemithi, nakwezinye izimo ezihlanzeke kakhulu, izinqubo zokuqinisekisa ukuhlanza i-probe ziyinkimbinkimbi, okungenzeka zandise izindleko zokuthobela imithetho (iradar engathintani inenzuzo enkulu ngenxa yokungathintani).
- Ingozi Yokugqokwa Kwe-Probe: Ezimweni lapho kukhona ukugeleza kwe-agitation noma i-turbulent media, kumele kufakwe imikhono yokuvikela i-probe ukuze kuvinjelwe ukuphuka ekushayweni.
VI. Umehluko Omkhulu Kusuka Ku-Radar Engaxhumani Nathi

Isiphetho
I-Guided Wave Radar iyisinqumo esifanele sokulinganisa izinga ezimweni zokusebenza eziyinkimbinkimbi, ikakhulukazi uma iphumelela kakhulu ezindaweni ezine-foam ephezulu, ezihlala zisebenza ngogesi ophansi, endaweni evalekile, noma ezindaweni ezibucayi. Kodwa-ke, uhlobo lwayo lokulinganisa ukuxhumana luveza izidingo zokugcinwa kanye nemikhawulo yokusetshenziswa. Ekukhetheni okusebenzayo, izici ezifana nezici eziphakathi nendawo (ukuthamba, ukugqwala, okuhlala kusebenza ngogesi), izimo zemvelo (izinga lokushisa, ingcindezi, isikhala), kanye nezidingo zokuhlanzeka kufanele zihlolwe ngokuphelele. Uma kudingeka, ingasetshenziswa kanye ne-radar engeyona eyokuxhumana ukuze imboze izimo eziningi.
