Iingenelo zeemitha zamanzi ze-Ultrasonic xa kuthelekiswa neemitha zamanzi zeMechanical

I. Uhlalutyo oluneenkcukacha lweeNzuzo

1. Ukuchaneka Okuphezulu Kokulinganisa, Akukho Zimpazamo Zokunxiba KwemishiniIimitha zamanzi ze-Ultrasonic zilinganisa ngokusekelwe kumgaqo wexesha okanye umahluko weDoppler, ngaphandle kweendawo ezihambayo ngaphakathi. Zisusa imiba yokuguguleka kunye nokugqwala kwezinto zoomatshini ezifana nee-impellers kunye neegiya, zigcina ukuchaneka kokulinganisa okuzinzileyo kwexesha elide (udidi lokuchaneka ukuya kuthi ga kwi-±0.5%FS, kunye ne-±0.2%FS kwezinye iimodeli ezichanekileyo). Ngaphezu koko, zinokubamba ngokuchanekileyo amazinga okuhamba aphantsi (ubuncinci bokuqala ukuhamba okuphantsi njenge-0.01m/s), ziphepha ingxaki eqhelekileyo "yokubalwa okungaphantsi kokuhamba" kwiimitha zamanzi zoomatshini, ezihlangabezana neemfuno zokulinganisa ezichanekileyo zokuhlawulelwa korhwebo. Ngokwahlukileyo koko, iimitha zamanzi zoomatshini zixhomekeke ekujikelezweni kwe-impeller ukuze zilinganiswe. I-impeller ithambekele ekugugulekeni nasekunyukeni ngenxa yokungcola emanzini emva kokusetyenziswa ixesha elide, okubangela ukuwohloka kokuchaneka kancinci kunye neempazamo ezibalulekileyo kumazinga okuhamba aphantsi, okufuna ukulinganiswa rhoqo kunye nokutshintshwa.
2. Ubomi beNkonzo ende, Iindleko zoLondolozo eziphantsi kakhuluIinxalenye eziphambili zeemitha zamanzi ze-ultrasonic ziisensors kunye neenxalenye ze-elektroniki, ezinoyilo oluvaliweyo nolungangeni manzi (udidi lokhuseleko ukuya kuthi ga kwi-IP68). Umzimba wemitha wenziwe kakhulu ngezinto ezingamelani nokugqwala ezifana nentsimbi engagqwaliyo ye-316L kunye neplastiki zobunjineli. Phantsi kweemeko zokusebenza eziqhelekileyo, ubomi benkonzo bunokufikelela kwiminyaka eli-10 ukuya kweli-15. Akukho mfuneko yokuqhaqha nokucoca rhoqo, kwaye kufuneka kuhlolwe kuphela iinxalenye ze-elektroniki ngamanye amaxesha, nto leyo enciphisa kakhulu iindleko zokusebenza kunye nokugcinwa kweenkampani zokubonelela ngamanzi. Nangona kunjalo, iimitha zamanzi zoomatshini zichaphazeleka kakhulu ngumgangatho wamanzi, kunye neengxaki ezibonakalayo zokuguguleka kunye nokuvaleka. Ubomi bazo benkonzo buhlala buyiminyaka emi-5 ukuya kweyesi-8 kuphela. Ukuqhaqha iimitha rhoqo ukuze kulinganiswe kunye nokutshintshwa kweenxalenye kuyimfuneko, kubandakanya iinkqubo zokulungisa ezinzima kunye neendleko eziphezulu.
3. Inqanaba eliphezulu lobuNgcali, Ukuziqhelanisa noLwakhiwo lweSmart Water Conservancy Iimitha zamanzi ze-Ultrasonic zixhasa ulwandiso olukrelekrele. Zinokudibanisa iinkqubo zonxibelelwano ezifana neMODBUS, M-BUS kunye neLoRa ukuze kufezekiswe ukuqokelelwa kwedatha ekude, ukujonga ngexesha langempela kunye nee-alamu ezingaqhelekanga (umz., ukuvuza kwamanzi kunye nezikhumbuzo zokunqunyulwa kwamanzi). Zinokuxhotyiswa ngeemodyuli ezihlawulelwayo kunye neevalvu zolawulo olukude, ukuhlangabezana neemfuno zeeprojekthi zamanzi akrelekrele zaphesheya. Ezinye iimodeli zinokujonga ngaxeshanye iiparameter ezininzi kubandakanya ubushushu bamanzi kunye noxinzelelo lwamanzi. Iimitha zamanzi zoomatshini zixhomekeke kakhulu ekubalweni koomatshini, zixhasa kuphela ukufundwa kwemitha ngesandla kwindawo kwaye azikwazi ukufikelela ekudlulisweni kwedatha ekude. Utshintsho olukrelekrele lunzima, kwaye ukufundwa kwemitha ngesandla akusebenzi kakuhle kwaye kunethuba lokwenza iimpazamo, okungahambelani nomkhwa wolawulo lwamanzi lwanamhlanje.
4. Ukuxhathisa Ukuhamba Kwamanzi Okuphantsi, Ukugcinwa Kwamandla kunye Nokuziqhelanisa Nomgangatho Wamanzi Onzima Ngoyilo olugudileyo lomjelo wokuhamba kwamanzi kwaye akukho zinto zithintelayo ezifana nee-impeller, iimitha zamanzi ze-ultrasonic azinalo phantse ulahleko loxinzelelo, nto leyo enokunciphisa ukusetyenziswa kwamandla kwimibhobho yokuhambisa amanzi. Okwangoku, azichaphazeleki yi-sediment kunye nezinto eziqinileyo ezixhonyiweyo emanzini, nto leyo ezenza zifaneleke kwiimeko ezinzima zomgangatho wamanzi ezifana nelindle kunye namanzi abuyiselweyo. Ngokwahlukileyo koko, iimitha zamanzi zoomatshini zisengozini yokungasebenzi kakuhle ngenxa yokuvaleka kwee-impeller okubangelwa bukungcola. Iimitha zamanzi zoomatshini zinokulahleka koxinzelelo oluthile njengoko ii-impeller kunye nezinye izinto zithintela ukuhamba kwamanzi. Zineemfuno eziphezulu zomgangatho wamanzi (zifuna amanzi acocekileyo ngaphandle kokungcola) njengoko ukungcola emanzini kunokubangela ukuxinana kwee-impeller ngokulula.
5. Amandla Aqinileyo Okuchasana Nokuphazamiseka, Ukusebenza Kokulinganisa Okuzinzileyo Iimitha zamanzi ze-Ultrasonic zinokusebenzisa uyilo olungelulo olwemagnethi ukuze zixhathise ngempumelelo ukuphazamiseka okuvela kumasimi angaphandle anamandla ombane, ziphephe ukulinganiswa okungachanekanga kweemitha zamanzi zoomatshini ezibangelwa kukuphazamiseka kombane. Ezinye iimodeli zixhotyiswe ngomsebenzi wokucoca isignali, okuvumela ukusebenza okuzinzileyo nakwiindawo ezintsonkothileyo zoshishino. Ukuphazamiseka kwentsimi yombane kunokuchaphazela ngokuthe ngqo ukujikeleza kwee-impellers kwiimitha zamanzi zoomatshini, okukhokelela kwiimpazamo zokulinganisa okanye nokumiswa kwemitha, okubangela amandla abuthathaka okuchasana nokuphazamiseka.
6. Ufakelo Oluguquguqukayo, Olulungelelaniswe Neemeko EzingakumbiIimitha zamanzi ze-Ultrasonic zixhasa ukufakwa okuthe tye, okuthe nkqo nokuthambekileyo, kunye neemfuno ezikhululekileyo zamacandelo eepayipi ezithe tye aphezulu nasezantsi (ezinye iimodeli zifuna kuphela i-3D ephezulu kunye ne-1D esezantsi). Zifanelekile kwiindawo ezintsonkothileyo zokufakela ezifana neendawo ezimxinwa kunye nemithombo engaphantsi komhlaba. Zigubungela uluhlu olubanzi lwee-calibers (DN15 - DN600), zinokuhlangabezana neemfuno zeemeko ezahlukeneyo kubandakanya izakhiwo zokuhlala, izakhiwo zorhwebo kunye nezityalo zoshishino. Iimitha zamanzi zoomatshini zihlala zinecala lokufakelwa elimiselweyo (ubukhulu becala ukufakelwa okuthe tye) kunye neemfuno ezingqongqo zamacandelo eepayipi ezithe tye (ngokuqhelekileyo i-10D ephezulu kunye ne-5D esezantsi). Zinee-calibers ezilinganiselweyo kwaye azikwazi ukuzivumelanisa kakuhle neemeko ezihamba ngokukhawuleza.
