Ukulinganisa ukugeleza kwamanzi ukungena nokuphuma ezindaweni zokuhlanzeka kwamanzi kanye nezindawo zokuhlanza indle kuyisilinganiso esibalulekile embonini yamanzi.Kuyisisekelo esibalulekile sokuthi amabhizinisi abale izinkomba ezinkulu zokukhiqiza nokusebenza ezifana nokuphumayo, izindleko zokukhiqiza, ukuvuza kwenethiwekhi yamapayipi kanye nokusetshenziswa kwamandla ngeyunithi ngayinye, futhi kuphinde kube isixhumanisi sokulinganisa embonini yamanzi.Ngaphakathi nangaphandle, ukukhethwa kwamamitha okugeleza kwamanzi kubaluleke kakhulu, indlela yokukhetha kahle amamitha okugeleza futhi uthuthukise izinga lokulinganisa nokutholwa kuwumsebenzi obaluleke kakhulu wamabhizinisi, lapho amamitha okugeleza kwe-ultrasonic athandwa kakhulu.
Uma kuqhathaniswa nezinye izinkambu, i-flowmeter esetshenziswa ekungeniseni nasekuthumeleni ukugeleza kwamanzi okukalwa kwamanzi okusebenza kwamanzi kanye nezitshalo zokuhlanza indle inezidingo zayo ezikhethekile.Okokuqala, ububanzi be-flowmeter bukhulu kakhulu, ngokuvamile ububanzi be-DN300mm-DN1000mm.Okwesibili, inani lokulinganisa ukugeleza kwamanzi likhulu, ngokuvamile izinkulungwane kuya emashumini ezinkulungwane ze-m3/h;Ukwengeza, ukuze kuqinisekiswe ukuthi izidingo zokuhlinzeka nokukala ukuhweba kwe-drainage zihlangene, i-flowmeter ekhethiwe ye-ultrasonic idinga ukunemba okuphezulu;Ngenxa yobubanzi obukhulu bemitha yokugeleza kanye nendawo yokufaka elinganiselwe, izidingo zesigaba sepayipi eliqondile azikwazi ukuba phezulu kakhulu.Mayelana nezici zokugeleza kwamanzi okungena nokuphuma, kufanele sinake izici ezilandelayo lapho sikhetha isikhathi sokugeleza kwe-ultrasonic:
I-Flowmeter ye-ultrasonic
1. Ububanzi obukhulu bepayipi lenqubo budinga ukulahlekelwa kwengcindezi yemitha yokuhamba ukuze kube kuncane ngangokunokwenzeka.Ngokuvamile, indlela yokunciphisa amapayipi wendawo ayisetshenziselwa ukwandisa izinga lokugeleza.
2. Kumapayipi asanda kuklanywa futhi afakiwe, izinga lokugeleza elifanele ngokuvamile liyakhethwa.Ngenxa yokuthi izinga lokugeleza koketshezi liphansi kakhulu, izinga lemitha lokugeleza likhulu, futhi ukutshalwa kwezimali okuhambisanayo kuthuluzi kuyakhuphuka.Izinga lokugeleza koketshezi liphezulu kakhulu, okuzobangela ukulahlekelwa kwengcindezi eguquguqukayo futhi kuholele ekwenyukeni kwezindleko zokusebenza, okungekona ukonga, kodwa ukukhethwa kufanele kushiye umkhawulo wokugeleza wokwandisa okuzayo;
3. Ngenxa yezinga eliphansi lokugeleza koketshezi, ukungcola oketshezini, udaka kanye nesikali kuzovela ngemva kwesikhathi eside sokusebenza, nokunye, kulula ukukufaka odongeni lwangaphakathi lwepayipi kanye ne-electrode.Ukuhlanzwa kwengxenye yokuxhumana phakathi kwethuluzi noketshezi kufanele kucatshangelwe kumklamo wobunjiniyela;
4. Ibanga lokulinganisa lensimbi likhulu.Ukugeleza kwamanzi athile ebusuku nasemini, ukugeleza kwasebusika nehlobo kuhluke kakhulu, kaningi izikhathi eziningana, ngakho-ke, lawa ma-flowmeters amanzi adinga ububanzi obukhulu ngokukhethekile;
5. Izinga lokuvikela lensimbi liphezulu.Amapayipi amakhulu amakhulu agqitshwa kakhulu ukuze kongiwe ukutshalwa kwezimali nendawo, futhi enyakatho, kuyisidingo sokunqanda ukuqandisa.Ngakho-ke, izinzwa zokugeleza ezihlukanisiwe zivame ukufakwa ku-instrument Wells.Ngenxa yemvula, ukuvuza kodonga nokuvuza kwepayipi nezinye izizathu ngokuvamile kubangela ukuthi izinga lamanzi emthonjeni likhuphuke futhi likhukhule inzwa yokugeleza, ngakho-ke idizayini kufanele ilinganiswe kulesi simo, khetha inzwa yokugeleza engaphansi kwamanzi, njengeleveli yokuvikela ye-IP68.Ngesikhathi esifanayo, ithuluzi kufanele livinjwe amanzi.
6. Ngenxa yokuthi ukuqinisekiswa kwamamitha amakhulu okugeleza kuvame ukuba nzima ukuwaqaqa, ukuthuthwa nokuwafaka, futhi inqubo ayikuvumeli ukuphazamiseka nokuvala shaqa, kuthenjwa ukuthi amamitha angomiswa alinganiswe ku-inthanethi.
I-Flowmeter ye-ultrasonic
Njengamanje, amamitha okugeleza abaluleke kakhulu asetshenziswa ezitshalweni zamanzi, izindawo zokuhlanza indle ukungena nokuphuma kumitha yokugeleza kwamanzi amamitha okugeleza kwe-ultrasonic kanye namamitha okugeleza kagesi, njll., kanye nenani elincane lama-plug-in flow flow metres, kanye nenani elikhulu. inombolo yezibuyekezo kumitha yokugeleza ehlakaniphile, enembayo ephezulu, enemisebenzi eminingi.Futhi uye waqaphela imodi yokuxhumana yedijithali, yohlobo lwebhasi (njenge-MODBUS, PROFBUS, HART, njll.) kanye nemodi yokuxhumana engenantambo ukuze kuzuzwe ukuqapha okukude, kanye nedatha yethrafikhi kude negumbi lokulawula elimaphakathi nendawo yokulawula yenkampani.Ukulinganisa ukugeleza kwamanzi ukungena nokuphuma ezindaweni zokuhlanzeka kwamanzi kanye nezindawo zokuhlanza indle kuyisilinganiso esibalulekile embonini yamanzi.Kuyisisekelo esibalulekile sokuthi amabhizinisi abale izinkomba ezinkulu zokukhiqiza nokusebenza ezifana nokuphumayo, izindleko zokukhiqiza, ukuvuza kwenethiwekhi yamapayipi kanye nokusetshenziswa kwamandla ngeyunithi ngayinye, futhi kuphinde kube isixhumanisi sokulinganisa embonini yamanzi.Ngaphakathi nangaphandle, ukukhethwa kwamamitha okugeleza kwamanzi kubaluleke kakhulu, indlela yokukhetha kahle amamitha okugeleza futhi uthuthukise izinga lokulinganisa nokutholwa kuwumsebenzi obaluleke kakhulu wamabhizinisi, lapho amamitha okugeleza kwe-ultrasonic athandwa kakhulu.
Uma kuqhathaniswa nezinye izinkambu, i-flowmeter esetshenziswa ekungeniseni nasekuthumeleni ukugeleza kwamanzi okukalwa kwamanzi okusebenza kwamanzi kanye nezitshalo zokuhlanza indle inezidingo zayo ezikhethekile.Okokuqala, ububanzi be-flowmeter bukhulu kakhulu, ngokuvamile ububanzi be-DN300mm-DN1000mm.Okwesibili, inani lokulinganisa ukugeleza kwamanzi likhulu, ngokuvamile izinkulungwane kuya emashumini ezinkulungwane ze-m3/h;Ukwengeza, ukuze kuqinisekiswe ukuthi izidingo zokuhlinzeka nokukala ukuhweba kwe-drainage zihlangene, i-flowmeter ekhethiwe ye-ultrasonic idinga ukunemba okuphezulu;Ngenxa yobubanzi obukhulu bemitha yokugeleza kanye nendawo yokufaka elinganiselwe, izidingo zesigaba sepayipi eliqondile azikwazi ukuba phezulu kakhulu.Mayelana nezici zokugeleza kwamanzi okungena nokuphuma, kufanele sinake izici ezilandelayo lapho sikhetha isikhathi sokugeleza kwe-ultrasonic:
