Amamitha okugeleza kwesiteshi esivulekileyimishini yokulinganisa eyinhloko yokugeleza kwamandla adonsela phansi okungacindezelwanga, esetshenziswa kabanzi ezitshalweni zendle zikamasipala, emiseleni yokudonsa amanzi yezimboni, emiseleni yokunisela yezolimo kanye nokuqapha imvelo yemifula. Ukunemba kwayo kokulinganisa kuncike kakhulu ekufakweni okujwayelekile kanye nokugcinwa njalo kwesayensi. Ukufakwa okungalungile kuzobangela ukuphambuka kokugeleza okuqhubekayo, kuyilapho ukuntuleka kokugcinwa okuvamile kuholela ekulahlekelweni kwesignali, ukuguga kwemishini kanye nesikhathi sokungasebenzi njalo. Lesi sihloko sihlela ngokuhlelekile amanothi abalulekile mayelana nokufakwa kanye nokugcinwa kwansuku zonke kwamamitha okugeleza esiteshi esivulekile.
Izidingo Zokufaka Eziyinhloko
1. Ukuhlelwa Kwesiteshi kanye neFlume/Weir
Isisekelo sokulinganisa okunembile sisekugelezeni kwamanzi okuzinzile nokubushelelezi. Okokuqala, abasebenzisi kumele bakhethe i-Parshall flume ejwayelekile ehambisanayo, i-triangular V-notch weir noma i-rectangular weir ngokusekelwe ekugelezeni okuncane kakhulu kanye nokuphezulu. Ama-tawrs angewona ajwayelekile enziwe ngokwezifiso azophula ubudlelwano bezibalo phakathi kwezinga lamanzi nokugeleza kwawo futhi alethe amaphutha okulinganisa angapheli. Okwesibili, kudingeka izingxenye zesiteshi eziqondile ezanele: okungenani ububanzi besiteshi obuphindwe kahlanu ohlangothini oluphezulu kanye nezikhathi ezintathu ohlangothini olungezansi. Ama-gold, amasango, amaconsi amanzi kanye namachibi odaka ngaphakathi kwalolu hlu kuzodala i-turbulence, i-backflow kanye ne-eddies, okuphambukisa izinga lamanzi langempela. Iphansi lesiteshi kumele libe yisicaba, ngaphandle kwama-protrusion noma ama-depression aqoqa udaka.
2. Ukufakwa Kwenzwa Yezinga
Iningiamamitha esiteshi avulekilethatha izinzwa ze-ultrasonic noma ze-radar ezifakwe ngaphezu kobuso bamanzi. I-probe kumele iqondaniswe ngqo nesikhungo sobuso bamanzi, kungabikho ukhula oluntantayo, igwebu, ama-bracket okusekela noma imicu elengayo evimba indlela yokudlulisa amagagasi omsindo. Ukubhukha ukuphakama kubalulekile: izinga lamanzi eliphakeme kakhulu kufanele lihlale okungenani ngamasentimitha angama-30 ngaphansi kwe-probe ukuvimbela ukucwila, kuyilapho izinga lamanzi eliphansi kakhulu kufanele libe ngaphakathi kwebanga lokulinganisa elisebenzayo le-sensor.
Izindawo zokufaka kufanele zigweme umhwamuko wamanzi oqinile, umusi oqothulayo oguquguqukayo kanye nokuphazamiseka okukhulu kwe-electromagnetic okuvela kumaphampu, ama-inverter kanye nezintambo ze-voltage ephezulu. Amabhulakhethi okufaka insimbi adinga ukugqoka okulwa nokugqwala, kanti izinzwa zangaphandle kufanele zifakwe izivikelo zelanga nemvula ukuze kugwenywe ukuchayeka ngqo esimweni sezulu esibi.
3. Izintambo zikagesi kanye nokuhlinzekwa kukagesi
Izintambo zesignali kanye nezintambo zikagesi kumele zibekwe ngokwehlukana ukuze kuncishiswe ukuphazamiseka kwesignali. Izintambo zokuxhumana ze-RS485 kufanele zisebenzise izintambo ezivikelwe, wonke amalunga avaliwe ngokuphelele ngemikhono engangeni manzi ukuze kuvinjelwe ukungena kwamanzi emvula. Ibhokisi lokudlulisela kanye nebhokisi lokuxhuma kufanele lifinyelele izinga elingangeni manzi le-IP65 noma ngaphezulu. Ukunikezwa kwamandla kagesi okuzinzile kwe-DC kuyadingeka; ukushintshashintsha kwamandla kagesi kuzobangela ukuphuma kwedatha okungazinzile, ngakho-ke kunconywa i-voltage stabilizer ezindaweni ezinamandla ashintshashintshayo.
Izindinganiso Zokunakekela Zansuku Zonke
1. Ukuhlanzwa Okuvamile Kwezinzwa
Ukungcola, uwoyela, izinsalela zedayi kanye nezinamathiselo zefayibha ebusweni beprobe kuzobonisa izimpawu ze-ultrasonic ngendlela engavamile futhi kubangele ukufundwa okungamanga. Abasebenzi kudingeka basule iprobe ngendwangu ethambile njalo; izikrwela eziqinile azivunyelwe ukugwema ukuklwebha ubuso bokuzwa. Kumanzi angcolile endwangu namakhemikhali anokungcola okukhulu, izesekeli zokuzihlanza ngokuzenzakalela zingafakelwa ukunciphisa imvamisa yokuhlanza ngesandla.
2. Ukugugulwa Kwesibani Nokugqwala Kwesiteshi
Udaka, indle kanye nodoti oqoqwe ngaphakathi kwe-flume kuzoshintsha indlela ephumelelayo yokugeleza kwamanzi, okuholela ekuphambukeni kokulinganisa okuqhubekayo. Abasebenzisi kufanele basuse udaka kanye nodoti ontantayo njalo ngenyanga, futhi balondoloze izindawo zokulahla udoti ukuze bavimbele udoti omkhulu ngaphambi kokuba bangene esigabeni sokulinganisa. Ngemva kwemvula enkulu noma ukudonsa amanzi okuphezulu kwezimboni, kudingeka ukuhlolwa okwengeziwe kokudonsa amanzi.
3. Ukuhlolwa Kwegesi Okuvamile
Abasebenzi kufanele bahlole igobolondo lokudlulisa, ama-cable joints kanye nama-junction box nyanga zonke ukuze babone ukuguga, imifantu noma ukuminyana kwamanzi ngaphakathi. Uma idatha igxuma ngokungahleliwe noma kungaveli isignali yokugeleza, hlola ukuphuka kwekhebula, izintambo ezikhululekile kanye nemithombo yokuphazamiseka kwe-electromagnetic. Kanye ngonyaka, yenza ukulinganisa ngesandla ngokuqhathanisa ukufundwa kwezinga lamanzi lemitha ne-staff gauge ejwayelekile ukuze ulungise amapharamitha ephuzu elingu-zero kanye nobubanzi.
4. Ukuvikelwa Kwesimo Sokusebenza Sesizini Nesikhethekile
Ebusika, izinzwa zangaphandle zidinga ukwelashwa kokungaqandisi. Iqhwa elimboze i-probe lizovimba ngokuphelele ukulinganiswa, ngakho-ke izinzwa ze-radar ziyathandwa ezindaweni ezibandayo. Kumanzi angcolile ane-asidi enamandla, i-alkali kanye ne-TDS ephezulu, hlola njalo ungqimba oluvimbela ukugqwala lwama-bracket nama-flume ukuze uvimbele ukuguquka kwesakhiwo okubangelwa ukugqwala.
Imisebenzi Engavunyelwe
Ungashintshi usayizi wama-flume ajwayelekile noma ama-weirs ngokungahleliwe; ungashintshi amapharamitha okubala ukugeleza kwangaphakathi kwesithumeli ngaphandle kwesiqondiso sochwepheshe. Ungalokothi uvumele inzwa icwiliswe ngamanzi agcwele isikhathi eside, futhi ugweme ukusebenzisa izintambo ezonakele ezingavikelwe ukuze udlulise isignali.
Isiphetho
Ukufakwa okujwayelekile kususa amaphutha amaningi okulinganisa ahlelekile, kuyilapho ukulungiswa okuvamile kwandisa impilo yesevisi futhi kuqinisekisa ukusebenza okuzinzile kwesikhathi eside. Ukulandela izincazelo ezingenhla kungakhulisa ukusebenza kweamamitha okugeleza kwesiteshi esivulekile, enikeza idatha yokugeleza ethembekile yokuqapha imvelo, ukuphathwa kwamanzi ezimbonini kanye nokuhlaliswa kokunisela kwezolimo.
