Intshayelelo
Kwimisebenzi yemizi-mveliso neyendalo, uninzi lwamanzi abalulekileyo alucocekanga kwaphela—cinga ngamanzi amdaka agcwele inkunkuma, ulwelo lwemigodi olugcwele inkunkuma, okanye ukungcola kwemizi-mveliso okunezimbiwa ezixhonyiweyo. Kwezi "zimbiwa zingcolileyo," ii-flowmeter zemveli zihlala zingaphumeleli: iimitha zoomatshini ziyavaleka, izixhobo ze-ultrasonic ziyasokola ukuphazamiseka kwesignali, kwaye ii-sensors eziphazamisayo zingcola ngokukhawuleza. Kulapho ii-flowmeter zeDoppler zikhanya khona. Ukusebenzisa isiphumo seDoppler—apho amaza esandi atsiba khona kwiisuntswana ezihambayo kulwelo ukuze abale isantya—ezi zixhobo ziguqula umngeni (izinto ezixhonyiweyo) zibe yinzuzo. Ngokungafaniyo neemitha eziqhelekileyo ezijonga ukungcola njengomqobo, ii-flowmeter zeDoppler zixhomekeke kuzo, zizenze zibe lolona khetho lukhethwayo lokulinganisa ukuhamba kwamanzi kwezinye zezona ndawo zinzima nezingcolileyo. Ukusuka kunyango lwamanzi amdaka kamasipala ukuya kwimisebenzi yemigodi, zibonelela ngedatha ethembekileyo, yexesha langempela egcina iinkqubo zisebenza kakuhle, zithobela, kwaye zingabizi kakhulu.
Kutheni iiDoppler Flowmeters ziphumelela kakhulu kwiiLiquids eziDirty
Imfihlo yempumelelo yee-flowmeter zeDoppler ngolwelo olungcolileyo ikwindlela yazo yokusebenza eyahlukileyo kunye noyilo. Ngokungafaniyo nee-flowmeter ze-ultrasonic ezilinganisa ukuhamba ngokudlulisa amaza esandi ngolwelo (oluphazanyiswa lula zizinto eziqinileyo), iimodeli zeDoppler zikhupha amaza esandi aqhelekileyo (ngesiqhelo yi-0.5–2 MHz) ajolise kwiisuntswana ezixhonyiweyo, amaqamza, okanye inkunkuma kulwelo. Xa la maza ebetha iisuntswana ezihambayo, i-frequency yazo iyatshintsha—olu tshintsho, olulinganiswa sisiva semitha, luhambelana ngokuthe ngqo nesantya solwelo. Ekubeni ubukho bezinto eziqinileyo bufuneka ukuze kufunyanwe ngokuchanekileyo, ulwelo olungcolileyo aluyongxaki kodwa luyimfuneko, lususa imiba yokuxinana kunye nokungcola echaphazela ezinye iimitha.
Enye inzuzo ephambili kukuba ayiphazamisi okanye ayiphazamisi kangako. Uninzi lweeDoppler flowmeters zibambekile: zincamathela ngaphandle kumbhobho, kungekho zinzwa ziphumayo kulwelo. Oku kuthetha ukuba akukho kudibana nolwelo olubolayo, olurhabaxa, okanye olungcolisiweyo—akukho nxalenye yokubola, akukho kuvuza okunokubangela ingozi, kwaye akukho mfuneko yokuvala inkqubo yokufakela okanye yokulungisa. Umzekelo, kumbhobho wamanzi amdaka othwala uthuli kunye nenkunkuma yendalo, iDoppler meter ebambekayo ithintela umngcipheko wokuvaleka kwenzwa okuya kwenza i-turbine meter ingasebenzi. Kwaneemodeli zeDoppler zohlobo lokufakelwa (ezisetyenziselwa iipayipi ezinkulu) zinezinzwa eziqinileyo, ezigqunywe ngentsimbi ezimelana nokukrala kunye nomonakalo weekhemikhali, ziqinisekisa ukuhlala ixesha elide kwiimeko ezinzima.
Ukongeza, iiDoppler flowmeters zibonelela ngokuhambelana okukhulu neentlobo zolwelo olungcolileyo. Ziphatha yonke into ukusuka kumanzi amdaka (anomxholo we-1-5% yezinto eziqinileyo) ukuya kwimigodi ye-slurries (ukuya kuthi ga kwi-40% yezinto eziqinileyo), ulwelo oluqinileyo olufana namanzi angcoliswe yioyile, kwanolwelo oluneziqabu zegesi (umz., amanzi amdaka angenawo umoya). Ukuchaneka kwazo (ngokwesiqhelo ±2-5% yokufundwa) kuhlala kufana kuzo zonke ezi zinto zimanzi ezahlukeneyo, zidlula ezinye iimitha ezifuna ulwelo olucocekileyo nolufanayo ukuze zisebenze ngokufanelekileyo.
Izicelo zeHlabathi lokwenyani kwiimeko zolwelo olungcolileyo
Ukuthembeka kweeDoppler flowmeters kulwelo olungcolileyo kuzenze zabaluleka kakhulu kumashishini amaninzi, nto leyo ethetha iingxaki zokulinganisa ezisele zikho ixesha elide.
Unyango lwamanzi amdaka kaMasipala
Izityalo zamanzi amdaka zezona zisetyenziswa kakhulu ziiDoppler flowmeters, apho zijonga khona ukuhamba kwamanzi amdaka angavuthwanga, udaka olusebenzayo, kunye nokungcola okucociweyo—zonke zigcwele izinto eziqinileyo, izinto eziphilayo, kunye nenkunkuma. Kwindawo yokungena, iiDoppler meters zilinganisa ukuhamba kwamanzi amdaka angavuthwanga ukuze kuphuculwe amandla okunyanga amaziko, ukuqinisekisa ukuba akukho mthwalo ugqithisileyo. Kwiitanki zomoya, zilandelela ukuhamba kwamanzi amdaka asebenzayo (umxube otyebileyo, otyebileyo kwiintsholongwane) ukuze kugcinwe amanqanaba afanelekileyo eoksijini, abalulekileyo ekuqhekezeni ukungcola. Ngokungafaniyo neemitha zoomatshini ezivalela amanzi amdaka, iimodeli zeDoppler zisebenza ngaphandle kokuphazamiseka, zinciphisa ixesha lokungasebenzi kakuhle kokugcinwa kwamanzi kwaye ziqinisekisa ukuthotyelwa kwemigangatho yokukhupha amanzi kwindalo esingqongileyo.
Ukwembiwa kwemigodi kunye nokucutshungulwa kwezimbiwa
Imisebenzi yokwemba ivelisa imithamo emikhulu ye-slurry—ingxubevange yamanzi kunye ne-ore etyumkileyo, isanti, okanye i-tailings (izinto ezilahlwayo). Ukulinganisa ngokuchanekileyo ukuhamba kwe-slurry kubalulekile ekuphuculeni ukubuyiswa kwezimbiwa kunye nokulawula inkunkuma. Ii-Doppler flowmeters zibalaseleyo apha: zisingatha i-slurry erhabaxa kakhulu (eneengceba ezifikelela kwiimilimitha ezininzi ngobukhulu) eziya kutshabalalisa ezinye iimitha. Umzekelo, kwimigodi yobhedu, ii-Doppler meter zilandelela ukuhamba kwe-slurry ye-ore ukuya kwiitanki zokudada, apho iikhemikhali zahlula ubhedu kwinkunkuma. Kulawulo lwe-slurry, zijonga ukuhamba kwe-slurry ukuya emachibini okugcina izinto, zithintela ukugcwala kunye nomonakalo ongqongileyo. Uyilo lwazo olungaphazamisiyo lukwathintela ukungcoliswa kwe-slurry, into ephambili exhalabisa ubunyulu bezimbiwa.
Ukwenziwa kweMizi-mveliso
Iinkqubo ezininzi zokwenza imveliso zivelisa ukungcola okungafunekiyo umlinganiselo ochanekileyo wokuhamba kwamanzi. Umzekelo, ekulungisweni kokutya, iiDoppler meter zijonga ukuhamba kwamanzi amdaka aqulethe iziqwenga zokutya, ioyile, kunye neesepha—ulwelo oluya kuvala iimitha zemveli. Kwimveliso yeekhemikhali, zilinganisa ukuhamba kolwelo olubolayo oluxutywe neemveliso eziqinileyo (umz., iipellets zeplastiki kwimveliso yepolymer), ukuqinisekisa ukulahlwa ngokukhuselekileyo kunye nokuthotyelwa kwemithetho yenkunkuma. Kwimizi-mveliso yepulp kunye nephepha, zilandelela ukuhamba kotywala obumnyama (imveliso etyebileyo, etyebileyo kwiikhemikhali yokukhupha imithi), zinceda imizi-mveliso ukuba ifumane amandla kotywala ngelixa ithintela ukonakala kwezixhobo.
Ulwakhiwo kunye nobunjineli bokwakha
Iindawo zokwakha zihlala zijongana namanzi angcolileyo avela ekumbiweni, ekuhlanjweni ngesamente, okanye ekuphumeni kwamanzi emvula (agcwele inkunkuma). IiDoppler flowmeters zisetyenziselwa ukulinganisa ukuhamba kwala manzi kwiinkqubo zonyango (umz., iitanki zenkunkuma) ngaphambi kokuba zikhutshwe, ukuqinisekisa ukuthotyelwa kwemithetho yendawo yokusingqongileyo ethintela amanzi agcwele inkunkuma ukuba angangeni kwiindlela zamanzi zendalo. Ukuphatheka kwazo—iimodeli ezininzi zisebenza ngebhetri kwaye kulula ukuzifaka okwethutyana—zenza zilungele iindawo zokwakha, apho ukuhamba kwamanzi kuhlala kungokwethutyana kwaye iindawo zitshintsha rhoqo.
