Kwintsimi yeumlinganiselo wokuhamba kwamanzi, iimitha zokuhamba ze-ultrasonic ezineetshaneli ezininzi ziye zavela njengesisombululo esisebenzayo nesinokuthenjwa, zibonelela ngeenzuzo ezahlukeneyo kunezixhobo zokulinganisa ukuhamba kwezixhobo zemveli. Ezi nzuzo zizenza zithandwe kakhulu kumashishini amaninzi, ukusuka kunyango lwamanzi amdaka ukuya kwioyile negesi, kunye nokuveliswa kombane ukuya ekucutshungulweni kweekhemikhali.
Ukuchaneka koMlinganiselo oPhezulu
Iimitha zokuhamba kwe-ultrasonic ezinemijelo emininzizenzelwe ukufezekisa ukuchaneka okuphawulekayo ekulinganisweni kokuhamba. Ngokusebenzisa iitshaneli ezininzi, zinokubamba iprofayili yesantya solwelo ngokupheleleyo. Itshaneli nganye ilinganisa ngokuzimeleyo isantya sokuhamba kwiindawo ezahlukeneyo ngaphakathi kwipayipi. Le ndlela yokulinganisa amanqaku amaninzi inciphisa ngempumelelo impembelelo yokuphazamiseka kokuhamba, njengaleyo ibangelwa ziingqiniba, iivalvu, okanye iipompo kwipayipi. Umzekelo, xa kuthelekiswa neemitha zokuhamba ze-ultrasonic ezinetshaneli enye okanye ezinye iimitha zokuhamba zesantya ezifana neemitha zokuhamba ze-electromagnetic, iimitha zokuhamba ze-ultrasonic ezinetshaneli ezininzi azinangxaki kangako kwimiqobo ephezulu. Kwinkqubo efakwe kakuhle, eneemfuno eziqhelekileyo zecandelo lepayipi yokungena ethe tye ye-5D phezulu kunye ne-2D ezantsi (apho u-D bububanzi bepayipi), ukuchaneka kokulinganisa kweemitha zokuhamba ze-ultrasonic ezinetshaneli ezininzi kunokufikelela phezulu kwi-0.5%. Ngokwahlukileyo koko, ukuphindaphindwa kweemitha zokuhamba ze-electromagnetic kudla ngokuba malunga ne-1/3 yolu chanekileyo, kwaye olo lweemitha zokuhamba ze-ultrasonic ezinetshaneli enye lumalunga ne-1/5. Oku kuchaneka okuphezulu kubalulekile kwizicelo apho ukulinganisa ukuhamba okuchanekileyo kubalulekile, njengakwisivumelwano sorhwebo, apho ukulinganisa ngokuchanekileyo kobungakanani bolwelo kuchaphazela ngokuthe ngqo iintengiselwano zemali.
Imfuneko Ephantsi YeeCandelo Zemibhobho Ethe Tye
Enye inzuzo ebalulekileyo yeemitha zokuhamba ze-ultrasonic ezineetshaneli ezininzi zikwimfuneko yazo ephantsi kakhulu yamacandelo epayipi ethe tye. Zisebenzisa indlela yokudibanisa kabini ukubala ukuhamba okusekwe kukusasazwa kwesantya kunye nokusasazwa kwendawo. Le algorithm iphucukileyo ibenza bakwazi ukulinganisa ngokuchanekileyo ukuhamba okusekwe kwiimeko zokuhamba kwe-laminar kunye ne-turbulent, ukuqinisekisa ukuchaneka kokudluliselwa komlinganiselo. Ngenxa yoko, zinokusebenza ngokufanelekileyo ngobude obufutshane bepayipi ethe tye xa kuthelekiswa nezinye iimitha zokuhamba ezininzi. Umzekelo, ngelixa ezinye iimitha zokuhamba zemveli zinokufuna i-20D okanye ngaphezulu yepayipi ethe tye phezulu ukuze zilinganiswe ngokuchanekileyo, iimitha zokuhamba ze-ultrasonic ezineetshaneli ezininzi zihlala zifuna i-10D phezulu kunye ne-3D ezantsi. Oku kuguquguquka kokufakelwa yinzuzo enkulu, ngakumbi kwiimeko apho indawo incinci okanye apho ukuguqula ulwakhiwo lwepayipi ekhoyo ukuze ilungele amacandelo epayipi ethe tye amade kubiza kakhulu okanye akusebenzi. Ikwavumela ukufakwa okuguquguqukayo ngakumbi kwiinethiwekhi zepayipi ezintsonkothileyo, ukwandisa uluhlu lwezicelo apho ezi mitha zokuhamba zingasetyenziswa khona.
Ubungakanani obuphezulu bokuvakalelwa
Iimitha zokuhamba kwe-ultrasonic ezinemijelo emininzizibonakaliswa bubuchule bazo bokulinganisa obuphezulu. Ukuchaneka kokulinganisa ixesha kwezi mitha kuphezulu kakhulu, kudla ngokufikelela kwinqanaba le-picosecond. Oku kuchaneka okuphezulu kokulinganisa ixesha kubenza bakwazi ukufezekisa umlinganiselo ochanekileyo wesantya sokuhamba kwamanzi nokuba kukwisantya sokuhamba esiphantsi. Umzekelo, banokulinganisa ngokuchanekileyo ukuhamba kwamanzi ngeesantya eziphantsi njenge-0.5 m/s ngokuchaneka kwe-0.5%. Olu buchule bubaluleke kakhulu kwizicelo apho izinga lokuhamba kwamanzi linokwahluka kakhulu, kuquka iimeko zokuhamba kwamanzi eziphezulu neziphantsi. Umlinganiselo wobubanzi, onokuba phezulu njenge-400:1, uthetha ukuba eziimitha yokuhambaI-s inokulinganisa ngokufanelekileyo ukuhamba kwamanzi kwi-spectrum ebanzi, ukusuka kumazinga okuhamba aphantsi kakhulu ngexesha lokulinda okanye amaxesha aphantsi emfuno ukuya kumazinga aphezulu okuhamba kwamanzi ngexesha lokusebenza okuphezulu. Olu buchule bokusingatha uluhlu olubanzi lwamazinga okuhamba kwamanzi ngaphandle kokunciphisa ukuchaneka kwenza iimitha zokuhamba ze-ultrasonic ezineetshaneli ezininzi zilungele iinkqubo ezahlukeneyo zoshishino apho ukuguquguquka kwesantya sokuhamba kwamanzi kuxhaphakileyo.
Ukuziqhelanisa noLwelo oluQokelelweyo kunye neMeko yokuSebenza
Ezi mitha zokuhamba ziyakwazi ukuziqhelanisa neentlobo ezahlukeneyo zolwelo kunye neemeko zokusebenza ezinzima. Umgaqo wazo wokulinganisa nge-ultrasonic awuchatshazelwa ziimpawu ezininzi zomzimba zolwelo, ezifana nobushushu, uxinzelelo, kunye ne-viscosity ngaphakathi koluhlu olubanzi. Oku kuzenza zifaneleke ukulinganisa iintlobo ngeentlobo zolwelo, kubandakanya amanzi acocekileyo, amanzi olwandle, ii-asidi, ii-alkali, iioyile, kwanolwelo olunenani elithile lezinto eziqinileyo ezixhonyiweyo okanye amaqamza (nangona ukubakho kwezinto eziqinileyo okanye amaqamza amaninzi kusenokuba nefuthe elithile, ngokubanzi zisebenza ngcono kunezinye iintlobo ezininzi zeemitha zokuhamba kwiimeko ezinjalo). Ukongeza, iimitha zokuhamba nge-ultrasonic ezineetshaneli ezininzi zinokusebenza kuluhlu olubanzi lobushushu, ukusuka kwi--10°C ukuya kwi-150°C kwiimeko ezininzi, kwaye zinokumelana noxinzelelo oluphezulu, okuzenza zifaneleke ukusetyenziswa kwiindawo ezinzima zoshishino. Umzekelo, kwimibhobho yeoyile negesi, apho ulwelo lunokuba ngumxube ontsonkothileyo wee-hydrocarbons ezinamaqondo obushushu ahlukeneyo kunye noxinzelelo, i-multi-channel ultrasoniciimitha zokuhambainokubonelela ngedatha yokulinganisa ukuhamba kwamanzi ethembekileyo.
Ayiphazamisi kwaye ayilungi
Uninziiimitha zokuhamba kwe-ultrasonic ezinemijelo emininziInika ukhetho lokulinganisa olungaphazamisiyo, ingakumbi abo banezinzwa ze-ultrasonic ezibambekayo zangaphandle. Le ndlela yokufaka engaphazamisiyo ayifuni ukusika okanye ukuguqula umbhobho, nto leyo eyenza lula inkqubo yokufaka kwaye inciphise iindleko zokufaka. Ikwanciphisa umngcipheko wokuvuza okanye ukuphazamiseka kokuhamba kolwelo. Ngaphezu koko, ekubeni ezi sensor zingadibani ngqo nolwelo, azinangxaki yokugqwala, ukukhukuliseka, okanye ukungcola, nto leyo enciphisa kakhulu iimfuno zokugcinwa. Ngokwahlukileyo koko, iimitha zokuhamba ezingenelelayo ezineendawo okanye iindawo ezihambayo ezinxibelelana ngqo nolwelo zinokufuna ukulungiswa rhoqo, ukulinganiswa, kunye nokutshintshwa ngenxa yokuguguleka okanye umonakalo ovela kulwelo. Kwanakwizinzwa ze-ultrasonic ezifakelweyo ezinxibelelana ngqo nolwelo, uninziiimitha zokuhamba kwe-ultrasonic ezinemijelo emininzizenzelwe ukuvumela ukuhamba rhoqo kunye nokufakwa koxinzelelo kunye nokugcinwa kwi-intanethi. Oku kuthetha ukuba ukuba i-sensor ichaphazeleka kukukala okanye eminye imiba ngokuhamba kwexesha, ingasuswa kwaye igcinwe ngaphandle kokuvala yonke inkqubo yepayipi, ukuqinisekisa ukusebenza okuqhubekayo kunye nokunciphisa ixesha lokungasebenzi.
Ukuguquguquka kunye nokuhambelana
Iimitha zokuhamba ze-ultrasonic ezineetshaneli ezininzi zinokuguquguquka kakhulu kwaye ziyahambelana neenkqubo ezahlukeneyo zoshishino. Zinokudityaniswa ngokulula nezinye izixhobo zokulawula inkqubo kunye nokubeka iliso. Umzekelo, zihlala ziza neendlela zonxibelelwano ezisemgangathweni ezifana ne-RS485, evumela unxibelelwano olungenamthungo kunye nabalawuli be-logic abacwangcisiweyo (ii-PLC), iinkqubo zolawulo ezisasazwe (ii-DCS), okanye ezinye iinkqubo zokufumana idatha kunye nokulawula. Oku kwenza kube lula ukujonga nokulawula isantya sokuhamba, kunye nokudibanisa idatha yokuhamba kwiinkqubo zolawulo lwezityalo ngokubanzi. Ukongeza, ezinye iimitha zokuhamba ze-ultrasonic ezineetshaneli ezininzi zinokuxhotyiswa ngeenzwa zobushushu ukulinganisa ukuhamba kunye nobushushu ngaxeshanye (kwimeko yokusetyenziswa kokufudumeza okanye kokupholisa), zibonelela ngedatha ebanzi ngakumbi yolawulo lwamandla kunye nokwenza ngcono inkqubo. Zinokwenziwa ngokwezifiso ukuhlangabezana neemfuno ezithile zesicelo, ezifana nobukhulu obahlukeneyo bemibhobho, izixhobo, kunye nokuchaneka kokulinganisa, okwenza zifaneleke kumashishini amaninzi kunye nezicelo.
Ukuqukumbela, iimitha zokuhamba ze-ultrasonic ezineetshaneli ezininzi zibonelela ngeenzuzo ezininzi ezenza ukuba zibe lukhetho olunomtsalane kwiimfuno zanamhlanje zokulinganisa ukuhamba. Ukuchaneka kwazo okuphezulu, iimfuno zecandelo lemibhobho ethe tye, uvakalelo oluphezulu, ukuziqhelanisa nolwelo oluntsonkothileyo kunye neemeko, uhlobo olungangeneleliyo, ukugcinwa okuphantsi, kunye nokuguquguquka kuzibeka njengesisombululo esiphambili kwicandelo le-umlinganiselo wokuhamba kwamanzi, okuqhuba ukusebenza kakuhle, ukuchaneka, kunye nokuthembeka kwiinkqubo zoshishino kwihlabathi liphela.
