Esimweni sokulinganisa izinga lezimboni nelomasipala—lapho isidingo sokuqapha uketshezi, izinto eziqinile, noma ama-slurry ngempumelelo, ngokuphepha, nangendlela engabizi kakhulu kubaluleke kakhulu—ama-geuge e-ultrasonic avele njengobuchwepheshe obamukelwe kabanzi. Ukusebenzisa ukusabalala nokubonakaliswa kwamagagasi omsindo avame kakhulu (ngaphezu kwebanga lokuzwa kwabantu, ngokuvamile kusuka ku-20 kHz kuya ku-200 kHz), lawa madivayisi anikeza indlela yokulinganisa engathintani egwema izingibe eziningi zezinzwa zemishini noma ezisekelwe ekuthinteni. Ngokungafani nama-geuge e-radar asebenzisa amagagasi kagesi noma ama-transmitter okucindezela angaphansi komhlaba adinga ukucwiliswa ngqo, ama-geuge e-ultrasonic alinganisa ukunemba, ukulula kokufakwa, kanye nokungabizi, okwenza afaneleke ezinhlobonhlobo zezicelo kuzo zonke izimboni. Kusukela ezindaweni zokucubungula ukudla ezincane kuya ezitshalweni ezinkulu zokwelashwa kwamanzi amdaka, ukuzivumelanisa nezimo kwazo kanye nezidingo zokunakekelwa okuphansi kuqinise isikhundla sazo njengesixazululo esisetshenziswayo sezidingo zokuqapha izinga lesimanje. Ngezansi ukuhlolwa okuningiliziwe kwesimiso sazo sokusebenza, izinzuzo ezibalulekile, izinhlelo zokusebenza ezahlukahlukene, kanye nokucatshangelwa kokusetshenziswa okuhle kakhulu.
I. Isimiso Sokusebenza: Ukusebenzisa Amagagasi Omsindo Ukuze Kulinganiswe Ngokunembile
Enhliziyweni yokusebenza kwe-ultrasonic level gauge yindlela eqondile kodwa ephumelelayo esekelwe esimisweni "sesikhathi sokundiza" samaza omsindo. Idivayisi evamile iqukethe izingxenye ezintathu eziyinhloko: i-transducer (esebenza njengomshini wokudlulisa kanye nokwamukela amaza e-ultrasound), iyunithi yokucubungula isignali, kanye nesibonisi sokubonisa noma sokuphuma.
Inqubo iqala lapho i-transducer ikhipha umsebe ogxilile wamagagasi e-ultrasonic ebusweni be-medium (uketshezi, i-powder, i-granular solid, noma i-slurry) okudingeka kulinganiswe izinga lawo. Njengoba la magagasi ehamba emoyeni (noma igesi) ngaphezu kwe-medium, ahlangana nobuso be-medium bese ebuyela emuva njengezibonakaliso ze-echo. I-transducer bese ithola la ma-echo abonakalisiwe bese ithumela isignali kuyunithi yokucubungula. Iyunithi yokucubungula ibala isikhathi esidlulile phakathi kokukhishwa kwegagasi lokuqala kanye nokwamukelwa kwe-echo—lesi “isikhathi sokundiza.”
Njengoba ijubane lomsindo kugesi ethile (isb., umoya) liyinto engaguquki eyaziwayo (engalungiselelwa izici ezifana nokushisa, ingcindezi, kanye nomswakama), iyunithi yokucubungula isebenzisa ifomula ibanga = (isivinini somsindo × isikhathi sokundiza) / 2 (ehlukaniswe ngo-2 ngoba igagasi liya endaweni ephakathi nendawo futhi libuyele emuva) ukuze linqume ibanga ukusuka ku-transducer kuya endaweni ephakathi nendawo. Ngokususa leli banga elilinganisiwe kusukela ekuphakameni okuphelele kwetangi noma isitsha okulinganisiwe kusengaphambili, igeyiji ibala izinga eliqondile lendawo ephakathi nendawo. Le datha ibe isiboniswa esikrinini sedivayisi noma idluliselwe njengesignali kagesi ejwayelekile (njenge-4–20 mA, i-RS485, noma i-Modbus) ukuze ihlanganiswe nezinhlelo zokulawula, amapulatifomu e-SCADA, noma amathuluzi okuqapha asekelwe efwini. Le nqubo yokungathintani isusa isidingo sokusebenzisana ngokomzimba nendawo ephakathi nendawo, isici esisekela izinzuzo eziningi ezibalulekile zobuchwepheshe.
II. Izinzuzo Eziyinhloko: Kungani Izinga Lokulinganisa I-Ultrasonic Livelele
1. Umklamo Ongathintani Uqinisekisa Ukuphepha Nokunakekelwa Okuphansi
Enye yezinzuzo ezibaluleke kakhulu zama-geuge e-ultrasonic level indlela yawo yokulinganisa engathintani. Ngokungafani nezinzwa zokuthintana (isb., ama-float switch, ama-capacitance probes, noma ama-submersible transmitters) okumele athinte i-medium, ama-geuge e-ultrasonic afakwa phezulu kwamatangi noma izitsha, okugcina i-transducer ihlukanisiwe nezinto ezilinganiswayo. Lokhu kubaluleke kakhulu ekusetshenzisweni okubandakanya imidiya eyingozi, ebolile, noma enamathelayo—njengamakhemikhali (ama-acid, izinyibilikisi), imikhiqizo kaphethiloli, noma ama-syrups e-food-grade.
Isibonelo, esitshalweni samakhemikhali esilinganisa izinga le-sulfuric acid egxilile, inzwa yokuxhumana ingaba sengozini yokugqwala noma yokulimala kwamakhemikhali, okudinga ukushintshwa njalo. I-gauge ye-ultrasonic, ngokuphambene, igwema ukuvezwa ngqo, inciphise izindleko zokulungisa futhi inciphise ingozi yokuvuza noma izehlakalo zokuphepha. Ngaphezu kwalokho, ukwakheka okungathintani kususa izinkinga ezifana nokungcola (kusuka ezindabeni ezinamathelayo njenge-molasses) noma ukuhuzuka (kusuka ezintweni eziqinile ezihlanganisiwe njengesihlabathi), okungonakalisa ukusebenza kwezinzwa zokuxhumana. Ukugcinwa njalo kwama-gauge e-ultrasonic kuvame ukuhilela ukuhlanza i-transducer njalo (ukususa uthuli noma udoti) kanye nokuhlolwa kokulinganisa—okuncane kakhulu kunokugcinwa okudingekayo kwezinye izindlela zemishini noma ezisekelwe ekuthinteni.
2. Ukufakwa Okulula Nokuguquguquka Kuzo Zonke Izinhlobo Zemikhumbi
Amageyiji e-Ultrasonic aziwa ngokulula kwawo kokufakwa, okwenza kube ukukhetha okuthandwayo kokubili kumaphrojekthi amasha kanye nokulungiswa kabusha. Ngokungafani namageyiji e-radar angadinga ukulungiswa ngokucophelela noma ama-pressure transmitter adinga ukungena kwethangi, amageyiji e-ultrasonic angafakwa phezu kwamathangi kusetshenziswa ama-flange, ukuxhumana okunezintambo, noma ngisho nezisekelo zamagnetic (zokufakwa kwesikhashana). Awadingi ukuguqulwa kwesakhiwo sethangi, okunciphisa isikhathi sokufakwa kanye nezindleko—okubalulekile ezindaweni ezinamafasitela aqinile okungasebenzi.
Lokhu kuguquguquka kudlulela ekuvumelaneni nezinhlobo ezahlukene zemikhumbi nobukhulu. Amageyiji e-Ultrasonic asebenza kahle emathangini avulekile, emithonjeni evaliwe, ema-silo, emathangini ane-agitators, ngisho nasezitsheni ezingakahleleki. Amamodeli athuthukile afaka ama-engeli e-beam alungisekayo (kusukela ku-8° omncane kuya ku-20° ububanzi) avumela abasebenzisi ukuthi bagweme izithiyo ngaphakathi kwethangi (njengemipayipi, ama-mixer, noma ama-baffle) ngokugxila i-ultrasonic beam endaweni ecacile ebusweni be-medium. Isibonelo, ethangini lesitshalo sokucubungula ukudla elisetshenziselwa ukuxuba imikhiqizo yobisi (elihlonyiswe nge-agitator), i-ultrasonic gauge encane ingabekwa ukuze idlule ama-agitator blades, iqinisekise ukufundwa okunembile ngaphandle kokuphazamiseka. Lokhu kuvumelana nezimo kwenza amageyiji e-ultrasonic afanele izimboni ezisukela kwezemithi (lapho amathangi ahlanzekile, angavimbeki avamile) kuya ekumbeni (lapho ama-silo amakhulu, anothuli agcina khona amalahle noma i-ore).
3. Ukuphumelela Ngezindleko Ngaphandle Kokuyekethisa Ukunemba
Uma kuqhathaniswa nobuchwepheshe obusezingeni eliphezulu njengezilinganiso zezinga le-radar noma izinzwa zezinga lenuzi, izilinganisi zezinga le-ultrasonic zinikeza ibhalansi enhle kakhulu yokusebenza kanye nezindleko. Zithengeka kakhulu kunezilinganiso ze-radar ngenkathi zisanikeza ukunemba okwanele kwezicelo eziningi zezimboni nezomasipala—ngokuvamile ngaphakathi kuka-±0.25% kuya ku-±1% webanga lokulinganisa, kuye ngemodeli kanye nezimo zemvelo. Lokhu kuzenza zifinyeleleke kumabhizinisi amancane naphakathi nendawo (ama-SME) okungenzeka angabi nesabelomali sezinzwa ze-premium kodwa asadinga ukuqapha izinga okuthembekile.
Isibonelo, isitshalo sokuhlanza amanzi amdaka sendawo (i-SME evamile ezinkonzweni zikamasipala) singasebenzisa ama-gauge e-ultrasonic ukukala izinga lendle emathangini okuqoqa noma ukungcola okuhlanziwe emachibini okugcina amanzi. Lawa ma-gauge ahlinzeka ngedatha enembile yokulawula ukusebenza kwephampu (isb., ukusebenzisa amaphampu lapho izinga lifika emkhawulweni) ngaphandle kwezindleko eziphezulu zezinhlelo ze-radar. Ngisho nasezikhungweni ezinkulu, ama-gauge e-ultrasonic avame ukusetshenziselwa amaphuzu okulinganisa esibili (isb., ukuqapha amathangi asizayo) lapho ukunemba okuphezulu kungabalulekile kodwa ukusebenza kahle kwezindleko kuyinto—umkhuba osiza ekunciphiseni isabelomali sezinto zokusebenza.
4. Ukufaneleka Kwemidiya Ehlanzekile Nengahambisani Nezimo
Nakuba ama-radar gauge ephumelela kakhulu ezimweni ezinzima (isb., umfutho ophezulu, amazinga okushisa aphezulu), ama-ultrasonic gauge afaneleka kakhulu ezindaweni ezihlanzekile, ezingadingi ugesi—izindawo lapho zivame ukusebenza khona kangcono kunezinzwa zokuthintana ezifana nama-capacitance probe (ancike ekuqhutshweni kogesi). Isibonelo, embonini yeziphuzo, ama-ultrasonic gauge asetshenziselwa ukukala izinga loketshezi olungadingi ugesi njengobhiya, iwayini, noma iziphuzo ezibandayo ematangini okugcina. Njengoba lawa ma-liquid engasebenzisi ugesi, ama-capacitance probe ahluleka ukukhiqiza isignali ethembekile, kodwa amagagasi e-ultrasonic awathinteki ugesi, okuqinisekisa ukufundwa okulinganayo.
Ngokufanayo, embonini yezemithi, lapho amanzi ahlanzekile noma izinyibilikisi ezihlanziwe (ezingenawo ugesi) zigcinwa khona emathangini engilazi noma epulasitiki, ama-gauge e-ultrasonic ahlinzeka ngesilinganiso esingangenisi ingozi yokungcolisa le nto. Amandla abo okusebenza ngezinto ezingangenisi ugesi andisa ukusetshenziswa kwabo ngale kwezimboni ezithembele kuketshezi oluhambisa ugesi (lapho kubusa khona ama-flowmeter kagesi noma izinzwa ze-capacitance), okwenza kube inketho eguquguqukayo yemikhakha enezidingo eziqinile zokuhlanzeka.
III. Izicelo Ezihlukahlukene: Kusukela Kumasevisi Kamasipala Kuya Ekukhiqizweni Kwezimboni
1. Amanzi Angcolile KaMasipala kanye Nokwelashwa Kwamanzi
Ama-geuge e-Ultrasonic level ayinto ebalulekile ezitshalweni zokuhlanza amanzi amdaka zikamasipala (ama-WWTP) kanye nezinhlelo zokuhlinzeka ngamanzi. Kuma-WWTP, aqapha izinga lendle eluhlaza emathangini okungenisa amanzi, aqinisekise ukuthi amaphampu adlulisela indle kumayunithi okuhlanza ngesivinini esizinzile ukuvimbela ukugcwala. Aphinde alinganise izinga lendle esebenzayo emathangini okungenisa umoya kanye nendle elungisiwe emachibini okugcina okugcina amanzi, esiza abaqhubi ukuthi bathuthukise izinqubo zokuhlanza futhi bahambisane nemithethonqubo yezemvelo (isb., ukuqinisekisa ukuthi amazinga endle awadluli imikhawulo yokukhipha).
Ezinhlelweni zokuphakelwa kwamanzi, ama-geuge e-ultrasonic asetshenziswa ukuqapha izinga lamanzi ezindaweni zokugcina amanzi, amathangi aphakeme, kanye nemibhoshongo yokusabalalisa. Isibonelo, inkampani yamanzi yedolobha ingafaka ama-geuge e-ultrasonic ethangini lamanzi ophahleni ukuze ilandele amazinga amanzi futhi iqalise ukugcwalisa kabusha lapho izinga lehla ngaphansi kwephuzu elibekiwe. Lokhu kuqinisekisa ukuhlinzekwa kwamanzi okuqhubekayo kubahlali ngenkathi kuvimbela ukugcwaliswa ngokweqile (okuchitha amanzi) noma ukugcwaliswa okunganele (okubangela ukuphazamiseka kwenkonzo).
2. Imboni Yokudla Neziphuzo
Imboni yokudla neziphuzo ithembele kuma-gauge e-ultrasonic ukuze ikwazi ukuphatha izinto ezihlanzekile, ezingaboli futhi ihambisane nezindinganiso zokuhlanzeka (isb., imithetho ye-FDA e-US noma i-EU 10/2011 yezinto zokuxhumana nokudla). Ezimbonini zokwenza ubhiya, balinganisa izinga lokukhishwa kwe-malt ematangini okuxuba nobhiya emikhunjini yokubilisa, baqinisekise ukuthi izithako zilinganiswa kahle futhi zihambisana nekhwalithi yomkhiqizo. Ezitshalweni zobisi, baqapha izinga lobisi, ukhilimu, noma i-yogurt ematangini okugcina, begwema izingozi zokungcola ezihambisana nezinzwa zokuxhumana.
Amageyiji amaningi e-ultrasonic aklanyelwe ukusetshenziswa kokudla anezindawo zokugcina insimbi engagqwali kanye nezilinganiso zokuvikela ze-IP67/IP68, okwenza zingabi namandla okuwasha (kusetshenziswa amanzi anomfutho ophezulu noma amakhemikhali okuhlanza) adingekayo ukuze kugcinwe inhlanzeko. Lokhu kuqina kuqinisekisa ukuthi amageyiji amelana nezinhlelo zokuhlanza ezinzima zezindawo zokucubungula ukudla.
3. Imboni Yamakhemikhali Neye-Petrochemical
Nakuba imboni yamakhemikhali ivame ukusebenzisa ama-radar gauges ukuze kusetshenziswe izinto ezibola kakhulu noma ezishisa kakhulu, ama-ultrasonic level gauges asetshenziswa kabanzi ezimweni ezingembi kakhulu—njengokulinganisa izinga lezinyibilikisi ezingabola, izihlanzi, noma umanyolo owuketshezi ematangini okugcina. Ezikhungweni ze-petrochemical, baqapha izinga likadizili, uphethiloli, noma uwoyela wokugcoba ematangini angaphezulu komhlaba, behlinzeka ngedatha enembile yokuphathwa kwempahla kanye nokuvimbela ukuchitheka.
Amageji e-ultrasonic athuthukisiwe anezitifiketi ezingaqhumi (isb., i-ATEX, i-IECEx) nawo asetshenziswa ezindaweni eziyingozi zezitshalo zamakhemikhali (isb., eduze nendawo yokugcina uketshezi oluvuthayo), lapho ukwakheka kwawo okungathintani kunciphisa ingozi yokushisa. Lawa mageji aqinisekisa ukuqapha kwezinga okuphephile nokuvumelana nezimo ezindaweni lapho ngisho nezinhlansi ezincane zingabangela ukuqhuma.
4. Ukuphathwa Kwezimayini Nokuphathwa Kwezinto Eziqinile
Embonini yezimayini, amageyiji e-ultrasonic level asetshenziswa ukukala izinga lezinto eziqinile (isb., amalahle, i-iron ore, i-limestone) ezindlini zokugcina amanzi kanye nama-hopper. Ngokungafani nezinzwa zemishini (isb., ama-rotary paddle switch) ezingavimba noma ziqhekeke lapho zithintana nezinto eziqinile ezirhabaxa, amageyiji e-ultrasonic agwema ukusebenzisana ngokomzimba, okuqinisekisa ukuthembeka kwesikhathi eside. Aphinde aphathe izimo ezinothuli ezivamile ezindaweni zokumba—amamodeli amaningi afaka ama-transducer amelana nothuli kanye nama-algorithms okucubungula isignali ahlunga ukuphazamiseka okuvela ezinhlayiyeni zothuli emoyeni.
Isibonelo, imayini yamalahle ingasebenzisa ama-gauge e-ultrasonic ukuqapha izinga lamalahle esili ngaphambi kokuba athuthelwe esiteshini sikagesi. Ama-gauge ahlinzeka ngedatha yesikhathi sangempela ukulawula ukugeleza kwamalahle kusuka esili kuya emabhandeni okuhambisa, ukuvimbela ukulayisha ngokweqile (okulimaza imishini) noma ukulayisha ngaphansi (okunciphisa ukusebenza kahle).
IV. Izinto Okumelwe Uzicabangele Ngokusebenzisa Okuhle
Nakuba ama-ultrasonic level gauge enikeza izinzuzo eziningi, awafaneleki kuzo zonke izinhlelo zokusebenza, futhi izici ezithile kumele zicatshangelwe ukuqinisekisa ukusebenza kahle:
- Izimo Zomoya: Ijubane lomsindo lithintwa izinga lokushisa, umswakama, kanye nengcindezi. Ukwehluka okukhulu kulezi zici (isb., umswakama ophezulu emshinini wephepha noma amazinga okushisa aphansi endaweni yokugcina impahla efrijini) kunganciphisa ukunemba. Amageji amaningi esimanje afaka isinxephezelo sokushisa esakhelwe ngaphakathi ukuze kuncishiswe le nkinga, kodwa abasebenzisi kufanele balinganisele igeji ukuze bahlangabezane nezimo ezithile zemvelo zokusetshenziswa kwayo.
- Igwebu Nomusi: Igwebu elijiyile elisebusweni boketshezi (isb., ethangini lokuxuba insipho) lingamunca noma lisakaze amagagasi e-ultrasonic, livimbele igeyiji ukuthi ingaboni i-echo ecacile. Ngokufanayo, amazinga aphezulu omhwamuko (isb., egumbini lebhoyila) angaphazamisa amagagasi omsindo. Ezimweni ezinjalo, abasebenzisi kungadingeka bakhethe amagagasi e-ultrasonic akhethekile anama-algorithms abekezelela igwebu noma bacabangele ubuchwepheshe obuhlukile njenge-radar.
- Izithiyo Zethangi: Izingxenye zethangi zangaphakathi (isb., ama-agitator, amapayipi, amaladi) zingabonakalisa amagagasi e-ultrasonic, zidale ama-echo angamanga aholela ekufundweni okunganembile. Ukuze kugwenywe lokhu, abasebenzisi kufanele bakhethe ama-gauge anama-angle amancane ogongolo bese bebeka i-transducer ukuze bagweme izithiyo, noma basebenzise amamodeli anezici zokucindezela i-echo ezihlunga amasignali angamanga.
Isiphetho
Amageyiji e-Ultrasonic level azisungule njengesisombululo esiguquguqukayo, esingabizi kakhulu, nesithembekile sokulinganisa amazinga kuzo zonke izimboni ezahlukahlukene. Ukwakheka kwawo okungathintani kuqinisekisa ukuphepha kanye nokugcinwa okuphansi, kuyilapho ukulula kwawo ukufakwa kanye nokuguquguquka kuwenza afaneleke ezinhlotsheni ezahlukahlukene zemikhumbi kanye nemidiya. Kusukela ekuhlanzweni kwamanzi amdaka kamasipala kuya ekucutshungulweni kokudla, ekukhiqizweni kwamakhemikhali kuya ekumbeni, la mageyiji aletha ukunemba nokuqina okudingekayo ukuze kuthuthukiswe ukusebenza, kulandelwe imithethonqubo, futhi kuncishiswe izindleko.
Nakuba zinemikhawulo ezimweni ezimbi kakhulu zomkhathi noma ezindaweni ezine-foam/vapor enamandla, intuthuko kwezobuchwepheshe—njengokuncishiswa kwezinga lokushisa, ama-algorithms abekezelela i-foam, kanye nemiklamo engaqhumi—iyaqhubeka nokwandisa ukusebenza kwayo. Njengoba izimboni emhlabeni wonke zamukela ukuzenzakalela kanye nokuqapha okuhlakaniphile, ama-gauge e-ultrasonic azohlala eyingxenye ebalulekile yezinhlelo zokulinganisa amazinga zesimanje, enikeza ibhalansi esebenzayo yokusebenza kanye nokufinyeleleka okuhlangabezana nezidingo zamabhizinisi amancane kanye nezindawo ezinkulu zezimboni. Kungakhathaliseki ukuthi kulinganiswa izinga lamanzi echibini ledolobha noma amalahle esibayeni sezimayini, ama-gauge e-ultrasonic afakazela ukuthi ukuqapha amazinga okuphumelelayo akudingi ubuchwepheshe obuyinkimbinkimbi noma obubizayo—isisombululo nje esilungiselelwe izidingo ezihlukile zesicelo.
