Inethiwekhi yamapayipi okukhipha amanzi iyindlela yokuphila engaphansi kwedolobha, enezici zezinguquko ezinkulu zokugeleza, amaphethini okugeleza ayinkimbinkimbi, izinga elibi lamanzi, kanye nemvelo ephansi yokufaka imishini.Ngakho-ke, uhlelo lwenethiwekhi yamapayipi okukhipha amanzi emadolobheni luyindawo eyisisekelo yokuphepha yedolobha, ethinta ngokuqondile ukuthuthukiswa komnotho kanye nokuzinza kwezimpilo zabantu, futhi idlala indima ebalulekile ekuthuthukisweni kwedolobha.Ngokuthuthuka nokuthuthukiswa kwamadolobhakazi, ukuphatha nokugcinwa kwawo sekuwumsebenzi ophuthumayo abaphathi bedolobha kanye nabathatha izinqumo.
Ukwengeza, kwimodi yokuphatha yendabuko, ukusebenza kwenethiwekhi yamapayipi kungaqondwa kuphela ngokuvula ikhava yomgodi ukuze uyibone.Akunakwenzeka ukuqonda kahle ukusebenza kwenethiwekhi yepayipi, futhi akunakwenzeka ukubona inethiwekhi yepayipi elidala noma elimele okokuqala.Kamuva, nakuba ukucutshungulwa kolwazi kwethulwe ezingeni eliphansi, i-AutoCAD, i-Excel nezinye izindlela zasetshenziselwa ukugcina idatha yenethiwekhi yepayipi yokudonsa emabhuloki, okwaqaphela kuphela ukuboniswa kwemephu eyisisekelo nemisebenzi yokubuza, futhi ayikwazanga ukubonisa izici zenethiwekhi eziyinkimbinkimbi. yenethiwekhi yamapayipi okukhipha amanzi.Akunakwenzeka ukubamba ngokunembile ukusebenza kwesikhathi sangempela kwepayipi.Futhi ayikwazi ukuhlinzeka ngesexwayiso esisebenzayo se-inthanethi kanye nokuqapha izinkinga ezifana nokugcwala kwamanzi emadolobheni, ukuchichima kwendle, ukuchithwa kwamanzi angcolile embonini ngokungemthetho, ukuchithwa ngokweqile kwamanzi angcolile ezimbonini, kanye nokugeleza okuxubile kwemvula nokukhucululwa kwendle.
Ngakho-ke, ukuqapha kokugeleza kwayo kunganikeza idatha eyisisekelo yokuxazulula ukugcwala kwamanzi emadolobheni, ukulimala kwamapayipi, nokuvinjwa kwamapayipi, futhi kunikeze isisekelo sokusebenza nokugcinwa kwenethiwekhi yamapayipi asemadolobheni.Ngesikhathi esifanayo, ukucwaninga okuhlelekile kokugeleza kwenethiwekhi yamapayipi asemadolobheni kungaqonda ngokuhlelekile isimo sokusebenza kwenethiwekhi yamapayipi, futhi kunikeze ukusekelwa kwedatha okuqondile yokwakhiwa kabusha nokwakhiwa kwenethiwekhi yamapayipi okukhipha amanzi.Ngenxa yolwazi lwenethiwekhi yamapayipi kamasipala, kuyadingeka ukukhetha amathuluzi afanelekile okuqapha ukugeleza ngokwezidingo zangempela ukuze kutholwe idatha yokugeleza enembile isikhathi eside futhi kuncishiswe inani lokugcinwa kwemishini.
Ngakho-ke, ngokuqapha kokugeleza, yimaphi ama-flowmeters afanele inethiwekhi yokudonsa amanzi?
Okokuqala, kufanele kukhethwe ngokuguquguquka okuqinile, okungasetshenziswa emithonjeni yezindaba eyinkimbinkimbi nasezindaweni ezizungezile, futhi akuthinteki kalula ngama-sediments amanzi kanye nezinto eziqinile ezimisiwe;ingakwazi ukuzivumelanisa nezinguquko ezisheshayo ekugelezeni kanye nezinga le-liquid, futhi inobubanzi obubanzi;inokugeleza okuhlanekezela okuthile Ikhono lokulinganisa;angabhekana nesimo sokugcwala kanyeamapayipi agcwele ingxenye.
Okwesibili, ukugeleza kutholakala ngokunembile;ukufakwa kulula, ukugcinwa kwansuku zonke kuncane futhi ukugcinwa kulula.Iningi lendawo yokufaka isemgodini, lapho ukunikezwa kwamandla nokuxhumana ngezintambo okunzima ukukufeza.Ngakho-ke, okokusebenza kudinga amandla ayo ebhethri futhi kunokubekezela okuthile ukuze kuncishiswe inani lokugcinwa.Ngaphezu kwalokho, idivayisi idinga ukuba nomsebenzi wokuxhumana okungenantambo, noma ingaxhunywa kwamanye amadivaysi ukuze ibone umsebenzi wokuxhumana okungenantambo;
Ngaphezu kwalokho, ngenxa yokuthi izinto zokugeleza ezisemgodini womgodi kungenzeka zibhekane nezikhukhula ezingazelelwe futhi eziphelele phakathi nenkathi yemvula, okokusebenza kudinga izinga eliphakeme lokungangeni kwamanzi ukuze kuvinjelwe umonakalo wemishini obangelwa izikhukhula, futhi izinga lokuvikela amanzi ngokuvamile liphakeme kune-IP68;Uma kunqunywa ngokwendawo ukuthi ukugxilwa kwe-methane evamile kuseduze nomkhawulo wokuqhuma, imishini yokugeleza engaqhumi idinga ukucatshangelwa.
Imishini yamanje yokugeleza engasetshenziswa kunethiwekhi yokudonsa amanzi isekelwe ikakhulukazi endleleni yezinga lokugeleza kwendawo.Lo mshini uyaguquguquka ekufakweni nasekusetshenzisweni, unokuvumelana nezimo okuqinile endaweni yokufaka, kanye nokunakekelwa okuphansi uma kuqhathaniswa.Lolu hlobo lwemishini yokugeleza lubizwa nge-ultrasonic Doppler flowmeter noma i-sewer flowmeter emakethe.
MayelanaI-Doppler Flowmeter
I-Ultrasound izohlakazeka lapho ihlangana nezinhlayiya ezincane eziqinile noma amabhamuza endleleni yokusakazeka, ngobaindlela yesikhathi sokuthuthaayisebenzi kahle lapho ikala uketshezi oluqukethe izinto ezinjalo.Ingasetshenziswa kuphela ukukala uketshezi oluhlanzekile.IIndlela ye-Dopplerisekelwe eqinisweni lokuthi amagagasi e-ultrasonic ahlakazekile.Ngakho-ke, indlela ye-Doppler ifaneleka ukulinganisa uketshezi oluqukethe izinhlayiya eziqinile noma amabhamuza.Nokho, ngenxa yokuthi izinhlayiya ezihlakazekile noma amabhamuza akhona ngokungahleliwe, ukusebenza kokudlulisa umsindo koketshezi nakho kuhlukile..
Ukwengeza, uma uketshezi olunomsebenzi ompofu wokudlulisa umsindo kulinganiswa, ukuhlakazeka kunamandla endaweni yesivinini sokugeleza okuphansi eduze kodonga lwamapayipi;kuyilapho uketshezi olunomsebenzi omuhle wokudlulisa umsindo luhlakazekile endaweni yesivinini esikhulu, okwenza isilinganiso se-Doppler Ukunemba kuphansi.Yize i-transducer edluliselayo kanye ne-transducer eyamukelayo kuhlukanisiwe, ingathola kuphela ukusakazeka endaweni emaphakathi yephrofayili yesivinini sokugeleza, kodwa ukunemba kokulinganisa kusephansi kunaleyo yendlela yesikhathi sokuthutha.
