Ukulinganisa ukuhamba kwamanzi nokungena nokuphuma kwimizila yamanzi kunye nezixhobo zokucoca ugutyulo ngumlinganiselo ongundoqo kushishino lwamanzi.Sisiseko esibalulekileyo kumashishini ukubala izalathisi ezinkulu zemveliso kunye nokusebenza ezifana nemveliso, iindleko zemveliso, ukuvuza kothungelwano lwemibhobho kunye nokusetyenziswa kwamandla kwiyunithi nganye, kwaye ikwalikhonkco lokulinganisa kwishishini lamanzi.Ngaphakathi nangaphandle, ukukhethwa kweemitha zokuhamba kwamanzi kubaluleke kakhulu, indlela yokukhetha ngokuchanekileyo iimitha zokuhamba kunye nokuphucula umgangatho wokulinganisa kunye nokufumanisa ngumsebenzi obaluleke kakhulu kumashishini, apho i-ultrasonic flow meters idume kakhulu.
Xa kuthelekiswa namanye amasimi, i-flowmeter esetyenzisiweyo ekungeniseni nasekuthumeleni umlinganiselo wokuhamba kwamanzi okusebenza kwamanzi kunye nezityalo zokucocwa kogutyulo zineemfuno zayo ezizodwa.Okokuqala, ububanzi be-flowmeter bukhulu kakhulu, ngokubanzi uluhlu lwe-DN300mm-DN1000mm.Okwesibini, ixabiso lokulinganisa ukuhamba kwamanzi likhulu, ngokubanzi amawaka ukuya kumashumi amawaka e-m3 / h;Ukongezelela, ukwenzela ukuba kuqinisekiswe ukuba iimfuno zokubonelela kunye nokulinganisa ukurhweba kwamanzi zidibene, i-flowmeter ekhethiweyo ye-ultrasonic idinga ukuchaneka okuphezulu;Ngenxa yobukhulu obukhulu bemitha yokuhamba kunye nesithuba sokufakela okulinganiselweyo, iimfuno zecandelo lombhobho elithe tye alikwazi ukuba phezulu kakhulu.Ngeempawu zokungena nokuphuma kwamanzi, kufuneka sithathele ingqalelo le miba ilandelayo xa sikhetha ixesha lokuhamba kwe-ultrasonic:
Ultrasonic flowmeter
1. Ububanzi obukhulu bombhobho wenkqubo bufuna ukulahleka koxinzelelo lwemitha yokuhamba ukuba ibe yincinci kangangoko kunokwenzeka.Ngokuqhelekileyo, indlela yokunciphisa umbhobho wendawo ayisetyenziselwa ukunyusa izinga lokuhamba.
2. Kwimibhobho esanda kuyilwa kunye nefakelwe, isantya sokuhamba esifanelekileyo sikhethwa ngokubanzi.Ngenxa yokuba izinga lokuhamba kwamanzi liphantsi kakhulu, i-caliber ye-flow meter inkulu, kwaye utyalo-mali oluhambelanayo kwisixhobo luyanda.Izinga lokuhamba kwamanzi liphezulu kakhulu, eliya kubangela ukulahleka koxinzelelo oluguquguqukayo kunye nokukhokelela ekwandeni kweendleko zokusebenza, ezingenako uqoqosho, kodwa ukhetho kufuneka lushiye umda wokuhamba ngokunyuka kwexesha elizayo;
3. Ngenxa yezinga eliphantsi lokuhamba kwamanzi, ukungcola kwi-fluid, i-silt kunye nesikali kuya kubonakala emva kwexesha elide lokusebenza, njalo njalo, kulula ukuyifaka kudonga lwangaphakathi lombhobho kunye ne-electrode.Ukucocwa kwecandelo loqhagamshelwano phakathi kwesixhobo kunye nolwelo kufuneka kuthathelwe ingqalelo kuyilo lobunjineli;
4. Uluhlu lokulinganisa lwesixhobo lukhulu.Amanye amanzi ahamba ebusuku nasemini, ubusika kunye nokuhamba kwehlobo kuyahluke kakhulu, kaninzi ngamaxesha amaninzi, ngoko ke, le mijelo yamanzi ifuna uluhlu olukhulu kakhulu;
5. Inqanaba lokukhusela isixhobo liphezulu.Imibhobho emikhulu edayamitha ubukhulu becala ingcwatywe ukuze kongiwe utyalo-mali kunye nendawo, kwaye emantla, ikwayimfuneko yokuchasa ukukhenkceza.Ke ngoko, iisensonsi zokwahlulahlula zifakwe ikakhulu kwisixhobo se Wells.Ngenxa yemvula, ukuvuza kodonga kunye nokuvuza kombhobho kunye nezinye izizathu zihlala zibangela ukuba umgangatho wamanzi equleni unyuke kwaye ukhukulise isivamvo sokuhamba, ngoko uyilo kufuneka luqikelelwe kulo mzekelo, khetha inzwa yokuqukuqela engaphantsi kwamanzi, efana nenqanaba lokhuseleko lwe-IP68.Kwangaxeshanye, isixhobo kakuhle kufuneka manzi.
6. Ngenxa yokuba ukuqinisekiswa kweemitha ezinkulu ze-runoff kudla kunzima ukukhupha, ukuthutha kunye nokufakela, kwaye inkqubo ayivumeli ukuphazamiseka kunye nokucima, kunethemba lokuba iimitha zinokomisa i-calibrated online.

Okwangoku, ezona mitha zokuhamba zibaluleke kakhulu ezisetyenziswa kwizityalo zamanzi, iiplanti zokucoca ugutyulo ukungena nokuphuma kwimitha yokuhamba kwamanzi ziimitha zokuqukuqela ze-ultrasonic kunye neemitha zokuhamba kwe-electromagnetic, njl. inani lohlaziyo kwiimitha ezikrelekrele, ezichanekileyo, ezisebenza ngeendlela ezininzi.Kwaye uye waqaphela i-wired, uhlobo lwebhasi yendlela yonxibelelwano yedijithali (efana ne-MODBUS, i-PROFBUS, i-HART, njl.) kunye nemowudi yonxibelelwano engenazintambo ukuphumeza ukubeka iliso kude, kunye nedatha ye-traffic kude negumbi lokulawula eliphakathi kunye negumbi lokulawula inkampani.Ukulinganisa ukuhamba kwamanzi nokungena nokuphuma kwimizila yamanzi kunye nezixhobo zokucoca ugutyulo ngumlinganiselo ongundoqo kushishino lwamanzi.Sisiseko esibalulekileyo kumashishini ukubala izalathisi ezinkulu zemveliso kunye nokusebenza ezifana nemveliso, iindleko zemveliso, ukuvuza kothungelwano lwemibhobho kunye nokusetyenziswa kwamandla kwiyunithi nganye, kwaye ikwalikhonkco lokulinganisa kwishishini lamanzi.Ngaphakathi nangaphandle, ukukhethwa kweemitha zokuhamba kwamanzi kubaluleke kakhulu, indlela yokukhetha ngokuchanekileyo iimitha zokuhamba kunye nokuphucula umgangatho wokulinganisa kunye nokufumanisa ngumsebenzi obaluleke kakhulu kumashishini, apho i-ultrasonic flow meters idume kakhulu.
Xa kuthelekiswa namanye amasimi, i-flowmeter esetyenzisiweyo ekungeniseni nasekuthumeleni umlinganiselo wokuhamba kwamanzi okusebenza kwamanzi kunye nezityalo zokucocwa kogutyulo zineemfuno zayo ezizodwa.Okokuqala, ububanzi be-flowmeter bukhulu kakhulu, ngokubanzi uluhlu lwe-DN300mm-DN1000mm.Okwesibini, ixabiso lokulinganisa ukuhamba kwamanzi likhulu, ngokubanzi amawaka ukuya kumashumi amawaka e-m3 / h;Ukongezelela, ukwenzela ukuba kuqinisekiswe ukuba iimfuno zokubonelela kunye nokulinganisa ukurhweba kwamanzi zidibene, i-flowmeter ekhethiweyo ye-ultrasonic idinga ukuchaneka okuphezulu;Ngenxa yobukhulu obukhulu bemitha yokuhamba kunye nesithuba sokufakela okulinganiselweyo, iimfuno zecandelo lombhobho elithe tye alikwazi ukuba phezulu kakhulu.Ngeempawu zokungena nokuphuma kwamanzi, kufuneka sithathele ingqalelo le miba ilandelayo xa sikhetha ixesha lokuhamba kwe-ultrasonic:
