Kwimeko yokulinganisa inqanaba lemizi-mveliso nelikamasipala—apho imfuneko yokujonga ulwelo, izinto eziqinileyo, okanye i-slurry ngokufanelekileyo, ngokukhuselekileyo, nangendlela engabizi kakhulu ibaluleke kakhulu—iigeyiji zenqanaba le-ultrasonic ziye zavela njengetekhnoloji eyamkelwe ngokubanzi. Ukusebenzisa ukusasazwa kunye nokubonakaliswa kwamaza esandi aqhelekileyo (ngaphaya kobubanzi bokuva kwabantu, ngokuqhelekileyo i-20 kHz ukuya kwi-200 kHz), ezi zixhobo zibonelela ngendlela yokulinganisa engahambelaniyo ethintela uninzi lweengxaki zeenzwa zoomatshini okanye ezisekelwe kuqhagamshelwano. Ngokungafaniyo neegeyiji zenqanaba le-radar ezisebenzisa amaza e-electromagnetic okanye ii-submersible pressure transmitters ezifuna ukuntywiliselwa ngqo, iigeyiji zenqanaba le-ultrasonic zilinganisela ukuchaneka, ukulula kokufakwa, kunye nokufikeleleka, okwenza zifaneleke kwiindidi ezahlukeneyo zezicelo kumashishini onke. Ukusuka kwizibonelelo zokucubungula ukutya ezincinci ukuya kwizityalo ezinkulu zonyango lwamanzi amdaka, ukuguquguquka kwazo kunye neemfuno zokugcinwa eziphantsi ziqinise isikhundla sazo njengesisombululo esisetyenziswa kwiimfuno zokujonga inqanaba lanamhlanje. Apha ngezantsi kukho uphando oluneenkcukacha lomgaqo wazo wokusebenza, iingenelo eziphambili, usetyenziso olwahlukeneyo, kunye nezinto eziqwalaselwayo zokusetyenziswa ngokufanelekileyo.
I. Umgaqo Wokusebenza: Ukusebenzisa Amaza Esandi Ukuze Ulinganise Ngokuchanekileyo
Eyona nto iphambili kwindlela esebenza ngayo i-ultrasonic level gauge yindlela elula kodwa esebenzayo esekelwe kumgaqo "wexesha lokubhabha" wamaza esandi. Isixhobo esiqhelekileyo sinezinto ezintathu eziphambili: i-transducer (esebenza njengomthumeli kunye nomkeli wamaza e-ultrasound), iyunithi yokucubungula isignali, kunye ne-display okanye i-output interface.
Inkqubo iqala xa i-transducer ikhupha umqadi ogxile kumaza e-ultrasonic kumphezulu we-medium (ulwelo, umgubo, i-granular solid, okanye i-slurry) ekufuneka ilinganiswe inqanaba lawo. Njengoko la maza ehamba emoyeni (okanye kwigesi) ngaphezulu kwe-medium, adibana nomphezulu we-medium aze abuye njengemiqondiso ye-echo. I-transducer emva koko ifumanisa la ma-echo abonakalisiweyo ize ithumele isignali kwiyunithi yokucubungula. Iyunithi yokucubungula ibala ixesha elidlulileyo phakathi kokukhutshwa kwamaza okuqala kunye nokwamkelwa kwe-echo—eli “lixesha lokubhabha.”
Ekubeni isantya sesandi kwigesi ethile (umz., umoya) siyinto eqhelekileyo eyaziwayo (enokulungiselelwa izinto ezifana nobushushu, uxinzelelo, kunye nokufuma), iyunithi yokucubungula isebenzisa umgama wefomula = (isantya sesandi × ixesha lokubhabha) / 2 (eyahlulwe ngo-2 kuba igagasi lihamba liye kwi-medium nasemva) ukumisela umgama ukusuka kwi-transducer ukuya kumphezulu we-medium. Ngokususa lo mgama ulinganisiweyo ukusuka kubude obupheleleyo betanki okanye inqanawa obulinganisiweyo kwangaphambili, igeyiji ibala inqanaba elichanekileyo le-medium. Olu lwazi emva koko luboniswa kwisikrini sesixhobo okanye ludluliselwe njengomqondiso wombane oqhelekileyo (ofana ne-4–20 mA, i-RS485, okanye i-Modbus) ukuze ludityaniswe neenkqubo zolawulo, amaqonga e-SCADA, okanye izixhobo zokubeka esweni ezisekelwe kwilifu. Le nkqubo yokungaqhagamshelani isusa isidingo sokusebenzisana ngokomzimba ne-medium, uphawu oluxhasa uninzi lweenzuzo eziphambili zobuchwepheshe.
II. Iingenelo eziphambili: Kutheni ii-Ultrasonic Level Gauges zibonakala
1. Uyilo olungadibaniyo luqinisekisa ukhuseleko kunye nokugcinwa okuphantsi
Enye yezona nzuzo zibalulekileyo zeegeyiji zenqanaba le-ultrasonic yindlela yazo yokulinganisa engadibaniyo. Ngokungafaniyo neesensa zoqhagamshelwano (umz., iiswitshi zokudada, ii-capacitance probes, okanye ii-submersible transmitters) ekufuneka zichukumise i-medium, iigeyiji ze-ultrasonic zifakelwa phezulu kwiitanki okanye kwiinqanawa, zigcina i-transducer ikude nezinto ezilinganiswayo. Oku kubaluleke kakhulu kwizicelo ezibandakanya imidiya enobungozi, ebolayo, okanye ene-viscous—ezifana neekhemikhali (ii-asidi, izinyibilikisi), iimveliso zepetroleum, okanye iisiraphu zezinga lokutya.
Umzekelo, kwisityalo seekhemikhali esilinganisa inqanaba le-sulfuric acid exineneyo, i-contact sensor ingaba semngciphekweni wokugqwala okanye umonakalo weekhemikhali, nto leyo efuna ukutshintshwa rhoqo. I-ultrasonic gauge, ngokwahlukileyo, ithintela ukuvezwa ngqo, inciphisa iindleko zokugcina kwaye inciphise umngcipheko wokuvuza okanye iziganeko zokhuseleko. Ukongeza, uyilo olungena-contact lususa imiba efana nokungcoliswa (kwi-sticky media efana ne-molasses) okanye ukukrala (kwizinto eziqinileyo ezifana nesanti), okunokonakalisa ukusebenza kwee-contact sensors. Ukugcinwa rhoqo kwee-ultrasonic gauges kudla ngokubandakanya kuphela ukucoca i-transducer rhoqo (ukususa uthuli okanye inkunkuma) kunye nokuhlolwa kokulinganiswa—okuncinci kakhulu kunokugcinwa okufunekayo kwezinye iindlela zoomatshini okanye ezisekelwe kunxibelelwano.
2. Ukufakela okulula kunye nokuguquguquka kwiintlobo zeenqanawa
Iigeyiji zenqanaba le-ultrasonic ziyaziwa ngokulula kwazo kokufakela, nto leyo eyenza ukuba zibe lukhetho olukhethwayo kwiiprojekthi ezintsha kunye nokulungiswa kwakhona. Ngokungafaniyo neegeyiji ze-radar ezinokufuna ukulungelelaniswa ngononophelo okanye ii-transmitters zoxinzelelo ezifuna ukungena kwetanki, iigeyiji ze-ultrasonic zinokufakwa phezu kweetanki kusetyenziswa ii-flanges, uqhagamshelo olunemisonto, okanye neziseko zemagnethi (zokufakelwa okwethutyana). Azidingi tshintsho kwisakhiwo setanki, nto leyo enciphisa ixesha lokufaka kunye neendleko—ibalulekile kwizakhiwo ezineefestile ezixineneyo zexesha lokungasebenzi.
Olu kuguquguquka lufikelela ekuhambelaneni neentlobo ezahlukeneyo zemikhumbi kunye nobukhulu. Iigeyiji ze-Ultrasonic zisebenza kakuhle kwiitanki ezivulekileyo, kwimikhumbi evaliweyo, kwiisilo, kwiitanki ezinee-agitators, kwanakwizikhongozeli ezimile ngendlela engaqhelekanga. Iimodeli eziphambili zinee-engile ze-beam ezihlengahlengiswayo (ukusuka kwi-8° encinci ukuya kwi-20° ebanzi) ezivumela abasebenzisi ukuba baphephe imiqobo ngaphakathi kwitanki (ezifana nemibhobho, ii-mixers, okanye ii-baffles) ngokujolisa i-ultrasonic beam kwindawo ecacileyo yomphezulu wesixhobo. Umzekelo, kwitanki yesityalo sokulungisa ukutya esetyenziselwa ukuxuba iimveliso zobisi (exhotyiswe nge-agitator), i-ultrasonic gauge enomqadi omxinwa inokubekwa ukuze idlule ii-agitator blades, ukuqinisekisa ukufundwa okuchanekileyo ngaphandle kokuphazamiseka. Oku kuguquguquka kwenza ii-ultrasonic gauges zifaneleke kumashishini aqala kwi-pharmaceuticals (apho iitanki ezingenazintsholongwane, ezingenaziphazamiso zixhaphakileyo) ukuya kwimigodi (apho ii-silos ezinkulu, ezinothuli zigcina amalahle okanye i-ore).
3. UkuSebenza kakuhle kweendleko ngaphandle kokulahla umngcipheko
Xa kuthelekiswa netekhnoloji ephezulu efana nee-radar level gauges okanye ii-nuclear level sensors, ii-ultrasonic level gauges zibonelela ngokulinganisela okugqwesileyo kokusebenza kunye neendleko. Zifikeleleka kakhulu kunee-radar gauges ngelixa zisabonelela ngokuchaneka okwaneleyo kwiimfuno ezininzi zemizi-mveliso kunye noomasipala—ngesiqhelo ngaphakathi kwe-±0.25% ukuya kwi-±1% yoluhlu lokulinganisa, kuxhomekeke kwimodeli kunye neemeko zokusingqongileyo. Oku kuzenza zifikeleleke kumashishini amancinci naphakathi (ii-SME) angenalo uhlahlo-lwabiwo mali lwee-premium sensors kodwa asafuna ukubekwa esweni okuthembekileyo kwamanqanaba.
Umzekelo, isityalo sokucocwa kwamanzi amdaka sendawo (i-SME eqhelekileyo kwiinkonzo zikamasipala) singasebenzisa ii-ultrasonic gauges ukulinganisa inqanaba le-lindle kwiitanki zokuqokelela okanye i-liff ecociweyo kwi-storage amachibi. Ezi gauges zibonelela ngedatha echanekileyo yokulawula imisebenzi yepompo (umz., ukuvuselela iipompo xa inqanaba lifikelela kumda) ngaphandle kweendleko eziphezulu zeenkqubo ze-radar. Kwanakwiindawo ezinkulu, ii-ultrasonic gauges zihlala zisetyenziselwa amanqaku okulinganisa esibini (umz., ukujonga iitanki ezincedisayo) apho ukuchaneka okuphezulu kungabalulekanga kodwa ukusebenza kakuhle kweendleko—ngumkhwa onceda ukunciphisa uhlahlo-lwabiwo mali lwezixhobo ngokubanzi.
4. Ukufaneleka kweMidiya ecocekileyo nengahambisi mandla
Nangona ii-radar gauges zigqwesile kwiimeko ezinzima (umz., uxinzelelo oluphezulu, amaqondo obushushu aphezulu), ii-ultrasonic gauges zilungele ngokukodwa imidiya ecocekileyo, engahambisani nombane—indawo apho zihlala ziphumelela ngakumbi kwii-contact sensors ezifana nee-capacitance probes (ezixhomekeke kwi-conductivity yesixhobo). Umzekelo, kwishishini leziselo, ii-ultrasonic gauges zisetyenziselwa ukulinganisa inqanaba le-non-conductive liquids ezifana nebhiya, iwayini, okanye iziselo ezibandayo kwiitanki zokugcina. Ekubeni ezi ziselo zingahambisani nombane, ii-capacitance probes ziya kusilela ukuvelisa isignali ethembekileyo, kodwa amaza e-ultrasonic awachaphazeleki yi-conductivity, okuqinisekisa ukufundwa okulinganayo.
Ngokufanayo, kwishishini lamayeza, apho amanzi acocekileyo okanye izinyibilikisi ezicociweyo (ezingenakho ukukhupha umoya) zigcinwa kwiitanki zeglasi okanye zeplastiki, iigeyiji ze-ultrasonic zibonelela ngokulinganisa okungangenisi mngcipheko wokungcolisa isixhobo. Amandla azo okusebenza ngezinto ezingasebenzisi mandla okukhupha umoya andisa ukusetyenziswa kwazo ngaphaya kwamashishini axhomekeke kulwelo oluqhuba umoya (apho ii-flowmeters ze-electromagnetic okanye ii-capacitance sensors zilawula khona), nto leyo ezenza zibe lukhetho oluguquguqukayo kumacandelo aneemfuno ezingqongqo zobumsulwa.
III. Izicelo ezahlukeneyo: Ukusuka kwiinkonzo zikaMasipala ukuya kwiMveliso yezeMizi-mveliso
1. Amanzi amdaka kaMasipala kunye noNyango lwaManzi
Iigeyiji zenqanaba le-ultrasonic zizinto ezibalulekileyo kwizityalo zonyango lwamanzi amdaka zikamasipala (ii-WWTP) kunye neenkqubo zokubonelela ngamanzi. Kwi-WWTP, bajonga inqanaba lendle eluhlaza kwiitanki zokungenisa amanzi, beqinisekisa ukuba iipompo zidlulisela indle kwiiyunithi zonyango ngesantya esizinzileyo ukuthintela ukugcwala. Bakwalinganisa inqanaba lendle esebenzayo kwiitanki zomoya kunye nendle ecociweyo kwidama lokugcina amanzi, benceda abaqhubi ukuba baphucule iinkqubo zonyango kwaye bathobele imithetho yokusingqongileyo (umz., ukuqinisekisa ukuba amanqanaba endle awadluli kwimida yokukhupha).
Kwiinkqubo zokubonelela ngamanzi, iigeyiji ze-ultrasonic zisetyenziselwa ukujonga inqanaba lamanzi kwiindawo zokugcina amanzi, iitanki eziphakamileyo, kunye neenqaba zokusasaza amanzi. Umzekelo, inkampani yamanzi yesixeko inokufaka iigeyiji ze-ultrasonic kwitanki yamanzi eluphahleni ukuze ilandelele amanqanaba amanzi kwaye iqalise ukuzalisa kwakhona xa inqanaba lihla ngaphantsi kwendawo ebekiweyo. Oku kuqinisekisa ukubonelelwa kwamanzi rhoqo kubemi ngelixa kuthintela ukuzaliswa kwamanzi amaninzi (okuchitha amanzi) okanye ukuzaliswa kwamanzi angaphantsi (okubangela ukuphazamiseka kwenkonzo).
2. Ishishini lokutya neziselo
Ishishini lokutya neziselo lixhomekeke kwiigeyiji zezinga le-ultrasonic ukuze likwazi ukuphatha izinto ezicocekileyo, ezingabolisiyo kwaye lithobele imigangatho yococeko (umz., imigaqo ye-FDA e-US okanye i-EU 10/2011 yezinto zokudibanisa ukutya). Kwiindawo zokuthengisa utywala, balinganisa inqanaba le-malt extract kwiitanki zokuxuba kunye nebhiya kwiimbiza zokubilisa, beqinisekisa umlinganiselo ochanekileyo wezithako kunye nomgangatho wemveliso ohambelanayo. Kwizityalo zobisi, bajonga inqanaba lobisi, ukhilimu, okanye iyogathi kwiitanki zokugcina, bephepha iingozi zongcoliseko ezinxulumene nezinzwa zokudibanisa.
Iigeyiji ezininzi ze-ultrasonic ezenzelwe ukusetyenziswa kokutya zineendawo zokugcina intsimbi engagqwaliyo kunye novavanyo lokhuseleko lwe-IP67/IP68, nto leyo eyenza ukuba zingabi namanzi amdaka (kusetyenziswa amanzi anoxinzelelo oluphezulu okanye iikhemikhali zokucoca) ezifunekayo ukugcina ucoceko. Oku kuhlala ixesha elide kuqinisekisa ukuba iigeyiji ziyakwazi ukumelana neeshedyuli zokucoca ezingqongqo zeendawo zokulungisa ukutya.
3. Ushishino lweeKhemikhali kunye neePetrochemical
Nangona ishishini leekhemikhali lidla ngokusebenzisa ii-radar gauges kwizicelo ezitshisa kakhulu okanye ezishushu kakhulu, ii-ultrasonic level gauges zisetyenziswa kakhulu kwiimeko ezingembi kangako—ezifana nokulinganisa inqanaba lezinyibilikisi ezingatshiyo, iisepha, okanye izichumisi ezingamanzi kwiitanki zokugcina. Kwiindawo ze-petrochemical, bajonga inqanaba ledizili, ipetroli, okanye iioyile zokuthambisa kwiitanki ezingaphezulu komhlaba, bebonelela ngedatha echanekileyo yolawulo lwempahla kunye nokuthintela ukuchitheka.
Iigeyiji eziphambili ze-ultrasonic ezineziqinisekiso zokumelana nokuqhuma (umz., i-ATEX, i-IECEx) zikwasetyenziswa kwiindawo ezinobungozi zezityalo ze-petrochemical (umz., kufutshane nendawo yokugcina ulwelo olunokutsha), apho uyilo lwazo olungachukumisiyo lunciphisa umngcipheko wokutsha. Ezi geyiji ziqinisekisa ukujonga amanqanaba ngokukhuselekileyo nangokuhambelanayo kwiindawo apho neentlantsi ezincinci zinokubangela ukuqhuma.
4. Ukuphathwa kweMigodi kunye noBuqu beZinto eziQinileyo
Kwishishini lezemigodi, iigeyiji zenqanaba le-ultrasonic zisetyenziselwa ukulinganisa inqanaba lezinto eziqinileyo ezinkulu (umz., amalahle, i-iron ore, i-limestone) kwii-silos nakwii-hoppers. Ngokungafaniyo nee-sensors zoomatshini (umz., ii-rotary paddle switches) ezinokuxinana okanye ziqhekeke xa zidibana nezinto eziqinileyo ezirhabaxa, iigeyiji ze-ultrasonic ziphepha ukusebenzisana ngokomzimba, ziqinisekisa ukuthembeka kwexesha elide. Zikwaphatha iimeko ezinothuli eziqhelekileyo kwiindawo zemigodi—iimodeli ezininzi zine-transducers ezimelana nothuli kunye nee-algorithms zokucubungula isignali ezihluza ukuphazamiseka okuvela kumasuntswana othuli emoyeni.
Umzekelo, umgodi wamalahle ungasebenzisa ii-ultrasound gauges ukujonga inqanaba lamalahle kwisisele ngaphambi kokuba athuthwe aye kwisikhululo samandla. Ezi gauges zibonelela ngedatha yexesha langempela ukulawula ukuhamba kwamalahle ukusuka kwisisele ukuya kwiibhanti zokuhambisa, ukuthintela ukugqithisa kakhulu (okonakalisa izixhobo) okanye ukulayisha ngaphantsi (okunciphisa ukusebenza kakuhle).
IV. Izinto ekufuneka ziqwalaselwe xa kusetyenziswa ngendlela efanelekileyo
Nangona ii-ultrasonic level gauges zibonelela ngeenzuzo ezininzi, azifanelekanga kuzo zonke izicelo, kwaye kufuneka kuqwalaselwe izinto ezithile ukuqinisekisa ukusebenza kakuhle:
- Iimeko zoMoya: Isantya sesandi sichaphazeleka bubushushu, ukufuma, kunye noxinzelelo. Utshintsho olukhulu kwezi zinto (umz., ukufuma okuphezulu kwindawo yokugaya iphepha okanye amaqondo obushushu aphantsi kwindawo yokugcina izinto efrijini) lunokunciphisa ukuchaneka. Iigeyiji ezininzi zanamhlanje ziquka ukubuyiselwa kobushushu okwakhelwe ngaphakathi ukunciphisa le ngxaki, kodwa abasebenzisi kufuneka balinganisele igeyiji kwiimeko ezithile zendalo ezisetyenziswayo.
- Igwebu kunye nomphunga: Igwebu elingqindilili eliphezu kolwelo (umz., kwitanki yokuxuba isepha) linokufunxa okanye lisasaze amaza e-ultrasonic, lithintele igeyiji ekufumaneni i-echo ecacileyo. Ngokufanayo, ubuninzi bomphunga (umz., kwigumbi lebhoyila) bunokuphazamisa amaza esandi. Kwiimeko ezinjalo, abasebenzisi banokufuna ukukhetha iigeyiji ezikhethekileyo ze-ultrasonic ezine-algorithms ezinyamezela igwebu okanye bacinge ngezinye iindlela zobuchwepheshe ezifana ne-radar.
- Izithintelo zeTanki: Izinto ezingaphakathi kwiTanki (umz., ii-agitators, iipayipi, iileli) zinokubonakalisa amaza e-ultrasonic, zenze ii-echoes ezingezizo ezikhokelela ekufundweni okungachanekanga. Ukuze kuthintelwe oku, abasebenzisi kufuneka bakhethe ii-gauges ezinee-engile ezimxinwa zemitha kwaye babeke i-transducer ukuze baphephe izithintelo, okanye basebenzise iimodeli ezineempawu zokucinezela i-echo ezihluza imiqondiso engezizo.
Isiphelo
Iigeyiji zenqanaba le-Ultrasonic ziye zazibonakalisa njengesisombululo esiguquguqukayo, esingabizi kakhulu, nesithembekileyo sokulinganisa amanqanaba kumacandelo amaninzi. Uyilo lwazo olungathinteliyo luqinisekisa ukhuseleko kunye nokugcinwa okuncinci, ngelixa ukulula kokufakwa kwazo kunye nokuguquguquka kwazo kuzenza zilungele iintlobo ezahlukeneyo zeenqanawa kunye nezixhobo. Ukususela ekunyangweni kwamanzi amdaka kamasipala ukuya ekucutshungulweni kokutya, ukwenziwa kweekhemikhali ukuya ekwembiweni, ezi geyiji zibonelela ngokuchaneka kunye nokuqina okufunekayo ukuze kuphuculwe ukusebenza, kuthotyelwe imigaqo, kwaye kuncitshiswe iindleko.
Nangona zinemida kwiimeko ezimandundu zomoya okanye kwiindawo ezine-foam/umphunga onzima, ukuqhubela phambili kwezobuchwepheshe—njengokubuyisela ubushushu, ii-algorithms ezinyamezela i-foam, kunye noyilo olungenakuqhuma—ziyaqhubeka nokwandisa ukusebenza kwazo. Njengoko amashishini kwihlabathi liphela esamkela ukwenziwa kwezinto ngokuzenzekelayo kunye nokubeka esweni okukrelekrele, ii-ultrasonic level gauges ziya kuhlala ziyinxalenye ebalulekileyo yeenkqubo zokulinganisa amanqanaba zanamhlanje, zibonelela ngokulinganisela okusebenzayo kokusebenza kunye nokufikeleleka okuhlangabezana neemfuno zamashishini amancinci kunye nezakhiwo ezinkulu zoshishino. Nokuba zilinganisa inqanaba lamanzi kwidama lesixeko okanye amalahle kwindawo yokumba, ii-ultrasonic level gauges zingqina ukuba ukubeka esweni amanqanaba okusebenzayo akudingi teknoloji inzima okanye ebiza kakhulu—sisisombululo esilungiselelwe iimfuno ezizodwa zesicelo.
