Iimitha zokuqukuqela ezahlukeneyo zisetyenziselwa ubulunga bamanzi amdaka ahlukeneyo

Ukuqukuqela sisixa esiguquguqukayo, ngoko ke umlinganiselo wokuqukuqela yitekhnoloji entsonkothileyo, esuka kumzimba wokuqukuqela olinganisiweyo, kuquka irhasi, ulwelo kunye nolwelo oluxutyiweyo lweempawu ezintathu ezahlukeneyo zolwelo; ishishini njengomzekelo, ukuveliswa kolwelo - umlinganiselo wamanzi, ngenxa yenkqubo yokuvelisa eyahlukileyo, yahlulwe ibe ngamanzi acocekileyo,turbidized amanzi eringi, amanzi amdaka aqengqelekayo entsimbi, amanzi amdaka anyibilikayo, amanzi amdaka asekhaya kunye nolunye uhlobo losasazo olwahlukileyo.

Ukhetho kunye nokusetyenziswa kweimitha yokuhamba zikwahluke ngokomgangatho wamanzi amdaka ahlukeneyo.Ukusetyenziswa, ukukhutshelwa kwamanzi amdaka ahlukeneyo kungasetyenziswa ngokwahlukileyoiimitha zokuhamba.

Iimitha zokuhamba nge-ultrasonic

Ultrasonicimitha yokuhamba ithatha iteknoloji ye-multi-pulse ephezulu, iteknoloji yokucwangcisa idijithali kunye neteknoloji yokulungiswa kweempazamo, ukwenzela ukuba imitha yokuhamba ikwazi ukuziqhelanisa nokusingqongileyo kwendawo yoshishino, umlinganiselo ulungele ngakumbi, uqoqosho kunye nechanekileyo.Imveliso ifikelela kwinqanaba eliphezulu ekhaya kwaye ngaphandle, inokusetyenziswa ngokubanzi kwi-petroleum, ikhemikhali, isinyithi, amandla ombane, unikezelo lwamanzi kunye neendawo zokuhambisa amanzi.Ikwalinganiswa nesantya sokuhamba ukubonakalisa ubungakanani bokuhamba.

Nangona i-ultrasonicimitha yokuhamba yavela kwi-1970s, ithandwa kakhulu kuba ingenziwa ibe yinto engabonakaliyo, kwaye inokudibaniswa nemitha yezinga lamanzi e-ultrasonic ukulinganisa ukuhamba okuvulekileyo, kwaye ayivelisi ukuphazamiseka kunye nokuchasana nombane.Ultrasonicimitha yokuhamba inokwahlulwa ibe luhlobo lwexesha kunye nohlobo lweDoppler ngokomgaqo wokulinganisa.

Ukongeza, i-ultrasonic Dopplerimitha yokuhamba eyenziwe nge-Doppler effect isetyenziswa kakhulu ukulinganisa i-medium kunye namasuntswana athile anqunyanyisiweyo okanye i-bubble medium, enemida ethile, kodwa isombulula ingxaki yokuba umahluko wexesha yi-ultrasonic.imitha yokuhamba inokulinganisa kuphela ulwelo olunye olucacileyo, kwaye ikwathathwa njengesixhobo esifanelekileyo somlinganiselo ongaqhagamshelwanga wemacala omabini ukuhamba.

I-electromagneticimitha yokuhamba

I-electromagneticimitha yokuhamba yinto entshaimitha yokuhamba iphuhliswe ngokukhawuleza ngophuhliso lobuchwephesha bombane ngeminyaka yoo-1950 kunye noo-1960. Imagnethi yombaneimitha yokuhamba luhlobo lwesixhobo esisebenzisa umgaqo wokungeniswa kwe-electromagnetic kunye nokulinganisa ukuhamba kolwelo oluqhubayo ngokokunyanzeliswa kwe-electromotive okubangelwa yi-conductive fluid ngokusebenzisa imagnethi yangaphandle. Inoluhlu lweempawu ezigqwesileyo, ezinokusombulula iingxaki ezinyeiimitha zokuhamba akukho lula ukuyisebenzisa, njengokuhamba okumdaka, umlinganiselo wokuhamba komhlwa.

Umjelo wokulinganisa umbhobho ogudileyo othe tye, ongayi kuvalwa.Ilungele ukulinganisa ulwelo olululwelo oluqinileyo olunezigaba ezibini eziqulathe amasuntswana aqinileyo, afana nentlaka yephepha, udaka, ilindle, njl.

Ukuthelekiswa kwe-ultrasonic kunye ne-electromagneticiimitha zokuhamba

I-electromagneticimitha yokuhamba kunye ne-ultrasonicimitha yokuhamba, ngenxa yokuba umjelo wokuhamba kweemitha awubeki naluphi na umqobo, akukho mqoboimitha yokuhamba, ilungele ukusombulula ingxaki yokulinganisa ukuhamba enzima yeklasiimitha yokuhamba, ngakumbi kumlinganiselo wokuhamba komlomo omkhulu kuneenzuzo ezibalaseleyo, yenye yophuhliso olukhawulezayo lweklasi yeimitha yokuhamba.

Ekugqibeleni, kugutyuloimitha yokuhamba ukhetho, nganyeimitha yokuhamba ineenzuzo zayo kunye nokungonakali, kwinkqubo yokucocwa kwamanzi amdaka, kufuneka ikhethwe ngokweemfuno zangempela.Ixabiso le-ultrasonicimitha yokuhamba iphantsi, ukuchaneka komlinganiselo kuphezulu, ukusebenza kuzinzile, ukufakela kunye nokugcinwa kulungeleka, ixabiso aliyi kuba phezulu nangaphezulu ngokunyuka kwedayamitha yombhobho, kodwa iya kuba yindleko ngakumbi nangakumbi ngenxa yokwanda kwesandi. indlela.I-electromagneticimitha yokuhamba inomlinganiselo ozinzile, uluhlu olubanzi lwesicelo kwaye inokulinganisa iindidi ezahlukeneyo zeendaba, kodwa kulula ukuphazanyiswa ngamaza ombane we-electromagnetic.Njengoko ububanzi bombhobho bukhula, ixabiso liba ngaphezulu nangaphezulu.
