Amamitha okugeleza ahlukene asetshenziselwa ikhwalithi yamanzi endle ehlukene

Ukugeleza kuyinani eliguqukayo, ngakho ukulinganisa ukugeleza kuwubuchwepheshe obuyinkimbinkimbi, obusuka kumzimba ogelezayo okaliwe, okuhlanganisa igesi, uketshezi noketshezi oluxubile lwezindawo ezintathu ezihlukene ezibonakalayo zoketshezi; imboni njengesibonelo, ukukhiqizwa kwe-liquid - isilinganiso samanzi, ngenxa yesistimu yokukhiqiza ehlukene, ihlukaniswe ngamanzi ahlanzekile,turbidized amanzi ayindandatho, amanzi angcolile agingqika ensimbi, amanzi angcolile ancibilikayo, amanzi angcolile asekhaya kanye neminye imithombo yezindaba ehlukene.

Ukukhethwa kanye nokusetshenziswa kweimitha yokugeleza nazo zihlukile ngokwekhwalithi ehlukene yokukhuculula indle.Ekusetshenzisweni, indle ehlukene ekhishiwe ingasetshenziswa ngendlela ehlukeneamamitha okugeleza.

Amamitha okugeleza kwe-ultrasonic

I-ultrasonicimitha yokugeleza ithatha ubuchwepheshe obuphambili be-multi-pulse, ubuchwepheshe bokucubungula idijithali kanye nobuchwepheshe bokulungisa amaphutha, ukuze imitha yokugeleza ikwazi ukuzivumelanisa nemvelo yendawo yezimboni, ukulinganisa kulula kakhulu, ukonga futhi kunembile.Imikhiqizo ifinyelela izinga eliphezulu ekhaya futhi phesheya, ingasetshenziswa kakhulu ku-petroleum, amakhemikhali, i-metallurgy, amandla kagesi, ukuhlinzekwa kwamanzi kanye nezinkambu zokudonsa amanzi.Kubuye kukalwe ngesivinini sokugeleza ukukhombisa ubukhulu bokugeleza.

Nakuba i-ultrasonicimitha yokugeleza yavela ngawo-1970, ithandwa kakhulu ngoba ingenziwa uhlobo olungathinteki, futhi ingaxhunyaniswa nemitha yezinga lamanzi e-ultrasonic ukukala ukugeleza okuvulekile, futhi ayikhiqizi ukuphazamiseka nokumelana noketshezi.Ultrasonicimitha yokugeleza ingahlukaniswa ngohlobo lomehluko wesikhathi kanye nohlobo lwe-Doppler ngokuya ngesimiso sokulinganisa.

Ngaphezu kwalokho, i-ultrasonic Dopplerimitha yokugeleza eyenziwe nge-Doppler effect isetshenziswa kakhulu ukukala i-medium ngezinhlayiya ezithile ezimisiwe noma i-bubble medium, enemikhawulo ethile, kodwa ixazulula inkinga yokuthi umehluko wesikhathiimitha yokugeleza ingakala kuphela uketshezi olulodwa olucacile, futhi lubhekwa njengethuluzi elikahle lokulinganisa okungathintana nayei-bi-directional ukugeleza.

I-electromagneticimitha yokugeleza

I-electromagneticimitha yokugeleza entshaimitha yokugeleza ithuthukiswe ngokushesha ngokuthuthukiswa kobuchwepheshe be-elekthronikhi ngeminyaka yawo-1950 kanye nawo-1960. I-electromagneticimitha yokugeleza iwuhlobo lwethuluzi elisebenzisa isimiso sokungeniswa kuka-electromagnetic futhi likala ukugeleza koketshezi oluqhutshwayo ngokuya ngamandla e-electromotive abangelwa uketshezi oluqhutshwayo ngokusebenzisa indawo kazibuthe yangaphandle.Inochungechunge lwezimpawu ezinhle kakhulu, ezingaxazulula izinkinga ezinyeamamitha okugeleza akulula ukuzisebenzisa, njengokugeleza okungcolile, isilinganiso sokugeleza kokugqwala.

Ishaneli yokulinganisa iyipayipi elibushelelezi eliqondile, elingeke livinjwe.Ilungele ukulinganisa uketshezi oluqinile lwezigaba ezimbili oluqukethe izinhlayiya eziqinile, njenge-pulp yephepha, udaka, indle, njll.

Ukuqhathaniswa kwe-ultrasonic ne-electromagneticamamitha okugeleza

I-electromagneticimitha yokugeleza kanye ne-ultrasonicimitha yokugeleza, ngenxa yokuthi ishaneli yokugeleza kwemitha ayibeki noma yikuphi ukuvinjelwa, azikho izithiyoimitha yokugeleza, ilungele ukuxazulula inkinga enzima yesilinganiso sokugeleza kwekilasiimitha yokugeleza, ikakhulukazi ekulinganisweni kokugeleza komlomo omkhulu kunezinzuzo ezivelele, kungenye yentuthuko esheshayo yekilasiimitha yokugeleza.

Ekugcineni, indleimitha yokugeleza ukukhetha, ngamunyeimitha yokugeleza inezinzuzo zayo kanye nokubi, ohlelweni lokuhlanza indle, kufanele kukhethwe ngokuvumelana nezidingo zangempela.Izindleko ze-ultrasonicimitha yokugeleza iphansi, ukunemba kokulinganisa kuphezulu, ukusebenza kuzinzile, ukufakwa nokugcinwa kulula, intengo ngeke ibe phezulu ngokunyuka kobubanzi bepayipi, kodwa izobiza kakhulu ngenxa yokwanda komsindo. indlela.I-electromagneticimitha yokugeleza inesilinganiso esizinzile, ububanzi bohlelo lokusebenza futhi ingakala imidiya ehlukahlukene, kodwa kulula ukuphazanyiswa amaza kagesi.Njengoba ububanzi bepayipi bukhula, intengo iya ngokuya ibiza kakhulu.
