Iimitha ezahlukeneyo zokuhamba kwamanzi amdaka zisetyenziselwa umgangatho owahlukeneyo wamanzi amdaka

Ukuhamba komoya bubuninzi obuguquguqukayo, ngoko ke ukulinganisa ukuhamba komoya bubuchwepheshe obuntsonkothileyo, obuvela kumzimba wokuhamba komoya olinganisiweyo, kuquka igesi, ulwelo kunye nolwelo oluxutyiweyo lweepropati ezintathu ezahlukeneyo zolwelo; Ukusuka kwiimeko zokulinganisa, kodwa nakwiindidi ezahlukeneyo, kushishino lwe-metallurgical njengomzekelo, ukuveliswa komlinganiselo wolwelo - amanzi, ngenxa yenkqubo eyahlukeneyo yemveliso, kwahlulwe ngamanzi acocekileyo,i-turbid amanzi ajikelezayo, amanzi amdaka aqengqelekayo entsimbi, amanzi amdaka anyibilikisayo, amanzi amdaka asekhaya kunye nezinye izinto ezahlukeneyo.

Ukukhethwa kunye nokusetyenziswa kweimitha yokuhamba zahlukile ngokwemigangatho eyahlukeneyo yelindle. Xa isetyenziswa, indle eyahlukeneyo ekhutshiweyo ingasetyenziswa kwiindawo ezahlukeneyoiimitha zokuhamba.

Iimitha zokuhamba kwe-ultrasonic

i-ultrasonicimitha yokuhamba yamkela iteknoloji ye-multi-pulse ephucukileyo, iteknoloji yokucubungula idijithali yesignali kunye neteknoloji yokulungisa iimpazamo, ukuze imitha yokuhamba ikwazi ukuziqhelanisa nemeko yendawo yemizi-mveliso, umlinganiselo ulula ngakumbi, unoqoqosho kwaye uchanekile. Iimveliso zifikelela kwinqanaba eliphezulu ekhaya nakwamanye amazwe, zingasetyenziswa kakhulu kwi-petroleum, iikhemikhali, i-metallurgy, umbane, unikezelo lwamanzi kunye namanzi amdaka. Ikwalinganiswa ngesantya sokuhamba ukuze ibonise ubungakanani bokuhamba.

Nangona i-ultrasoundimitha yokuhamba yavela ngeminyaka yoo-1970, ithandwa kakhulu kuba inokwenziwa ibe luhlobo olungadibaniyo, kwaye inokudityaniswa nemitha yamanzi ye-ultrasonic ukulinganisa ukuhamba okuvulekileyo, kwaye ayivelisi ukuphazamiseka kunye nokumelana nolwelo.imitha yokuhamba inokwahlulwahlulwa ngohlobo lomahluko wexesha kunye nohlobo lweDoppler ngokwemigaqo yokulinganisa.

Ukongeza, i-ultrasound Doppler iyasebenza.imitha yokuhamba eyenziwe nge-Doppler effect isetyenziswa kakhulu ukulinganisa i-medium ngee-particles ezithile ezixhonyiweyo okanye i-bubble medium, enemida ethile, kodwa isombulula ingxaki yokuba umahluko wexesha we-ultrasoundimitha yokuhamba inokulinganisa ulwelo olunye olucacileyo kuphela, kwaye ikwathathwa njengesixhobo esifanelekileyo sokulinganisa ngaphandle kokuthintanaicala eliya kwicala elibini ukuhamba.

I-electromagneticimitha yokuhamba

I-electromagneticimitha yokuhamba yinto entshaimitha yokuhamba yaphuhliswa ngokukhawuleza ngophuhliso lwetekhnoloji ye-elektroniki ngeminyaka yoo-1950 noo-1960. I-electromagneticimitha yokuhamba Luhlobo lwesixhobo esisebenzisa umgaqo wokungenisa i-electromagnetic kwaye silinganisa ukuhamba kolwelo oluqhubayo ngokwe-electromotive force ebangelwa lulwelo oluqhubayo nge-magnetic field yangaphandle. Sineempawu ezininzi ezintle, ezinokusombulula iingxaki ezibangelwa zezinyeiimitha zokuhamba Akulula ukuzisebenzisa, njengokuhamba kokungcola, ukulinganisa ukuhamba komhlwa.

Umjelo wokulinganisa ngumbhobho othe tye ogudileyo, ongenakuvaleka. Ufanelekile ukulinganisa ulwelo oluqinileyo olunezigaba ezimbini oluqulethe amasuntswana aqinileyo, afana ne-pulp yephepha, udaka, amanzi amdaka, njl.

Uthelekiso lwe-ultrasonic kunye ne-electromagneticiimitha zokuhamba

I-electromagneticimitha yokuhamba kunye ne-ultrasoundimitha yokuhamba, kuba umjelo wokuhamba kwemitha awubeki naluphi na uthintelo, akukho thinteloimitha yokuhamba, ifanelekile ukusombulula ingxaki enzima yokulinganisa ukuhamba komoya yodidi lweimitha yokuhamba, ingakumbi ekulinganisweni komlomo omkhulu, oku kuneenzuzo ezibalaseleyo, yenye yophuhliso olukhawulezayo lodidi lweimitha yokuhamba.

Okokugqibela, malunga nelindleimitha yokuhamba ukhetho, nganyeimitha yokuhamba inezibonelelo kunye neengxaki zayo, kwinkqubo yokucoca amanzi amdaka, kufuneka ikhethwe ngokweemfuno zokwenyani. Ixabiso le-ultrasoundimitha yokuhamba iphantsi, ukuchaneka kokulinganisa kuphezulu, ukusebenza kuzinzile, ukufakelwa kunye nokugcinwa kulula, ixabiso aliyi kuba phezulu nangakumbi ngokwanda kobubanzi bombhobho, kodwa kuya kuba kubiza kakhulu ngenxa yokwanda kwendlela yesandi. I-electromagneticimitha yokuhamba inomlinganiselo ozinzileyo, uluhlu olubanzi lokusetyenziswa kwaye inokulinganisa iindidi ezahlukeneyo zemidiya, kodwa kulula ukuphazanyiswa ngamaza e-electromagnetic. Njengoko ububanzi bombhobho bukhula, ixabiso liya libiza ngakumbi nangakumbi.
