Uthungelwano lwemibhobho ye-drainage yindlela yokuphila ephantsi komhlaba yesixeko, eneempawu zotshintsho olukhulu lokuhamba, iipateni zokuhamba ezintsonkothileyo, umgangatho ombi wamanzi, kunye nemekobume yofakelo lwezixhobo ezingekho mgangathweni.Ngoko ke, inkqubo yothungelwano lombhobho wokuhambisa amanzi edolophini yindawo esisiseko yokhuseleko yesixeko, echaphazela ngokuthe ngqo uphuhliso lwezoqoqosho kunye nokuzinza kobomi babantu, kwaye idlala indima ebalulekileyo kuphuhliso lwesixeko.Ngenkqubela kunye nophuhliso lwezixeko, ulawulo nokugcinwa kwazo kube ngumsebenzi ongxamisekileyo ojongene nabaphathi besixeko kunye nabenzi bezigqibo.
Ukongezelela, kwindlela yokulawula yendabuko, ukusebenza komnatha wombhobho kunokuqondwa kuphela ngokuvula isigqubuthelo somngxuma wokuyigcina.Akunakwenzeka ukuqonda ngokuchanekileyo ukusebenza komnatha wombhobho, kwaye akunakwenzeka ukufumanisa inethiwekhi yombhobho endala okanye eyonakalisiweyo okokuqala.Kamva, nangona inkqubo yolwazi yaziswa kwinqanaba eliphantsi, i-AutoCAD, i-Excel kunye nezinye iindlela zasetyenziselwa ukugcina idatha yombhobho we-drainage wombhobho kwiibhloko, eziqaphela kuphela umboniso wemephu esisiseko kunye nemisebenzi yokubuza, kwaye ayikwazanga ukubonisa iimpawu zenethiwekhi eziyinkimbinkimbi. yothungelwano lwemibhobho yokuhambisa amanzi.Akunakwenzeka ukuba ubambe ngokuchanekileyo ukusebenza kwexesha langempela lombhobho.Kananjalo ayikwazi ukubonelela ngesilumkiso esisebenzayo se-intanethi kunye nokubeka iliso kwiingxaki ezinje ngokugcwala kwamanzi ezidolophini, ukuphuphuma kwelindle, ukukhutshelwa ngokungekho mthethweni kwamanzi amdaka avela kwimizi-mveliso, ukukhutshwa okugqithisileyo kwamanzi amdaka avela kwimizi-mveliso, kunye nokuhamba okuxutyiweyo kwemvula kunye nogutyulo.
Ke ngoko, ukubekwa esweni kokuhamba kwayo kunokubonelela ngedatha eyisiseko yokusombulula ukugcwala kwamanzi ezidolophini, ukonakaliswa kwemibhobho, kunye nokuvalwa kwemibhobho, kunye nokubonelela ngesiseko sokusebenza kunye nokugcinwa komnatha wemibhobho yasezidolophini.Kwangaxeshanye, uphononongo olucwangcisiweyo lokuhamba kothungelwano lombhobho wedolophu lunokuqonda ngokucwangcisiweyo ubume bokusebenza kombhobho wombhobho, kwaye lunike inkxaso ethile yedatha yokwakhiwa ngokutsha kunye nokwakhiwa komnatha wombhobho wokuhambisa amanzi.Ngenxa yobungcali bothungelwano lwemibhobho kamasipala, kuyimfuneko ukukhetha izixhobo ezifanelekileyo zokujonga ukuhamba ngokweemfuno zokwenyani zokufumana idatha yokuqukuqela echanekileyo ixesha elide kunye nokunciphisa isixa sokugcinwa kwesixhobo.
Ke, ukujonga ukuhamba, zeziphi ii-flowmeters ezifanelekileyo kuthungelwano lokuhambisa amanzi?
Okokuqala, kufuneka kukhethwe ngokuguquguquka okuqinileyo, okungasetyenziswa kwimidiya enzima kunye neendawo ezisingqongileyo, kwaye ayichaphazeli lula i-sediments yamanzi kunye nezixhobo ezimisiweyo;iyakwazi ukulungelelanisa utshintsho olukhawulezayo lokuhamba kunye nenqanaba le-liquid, kwaye inoluhlu olubanzi;inomqukuqelo othile wokubuyela umva Isakhono sokulinganisa;inokujongana nemeko epheleleyo kunyeimibhobho ezaliswe ngokuyinxenye.
Okwesibini, ukuhamba kufunyenwe ngokuchanekileyo;ukufakela kulula, ukugcinwa kwemihla ngemihla kuncinci kwaye ukugcinwa kulula.Uninzi lwendawo yokufakela ikwindawo yokusebenzela, apho unikezelo lwamandla kunye nonxibelelwano lweengcingo kunzima ukufezekisa.Ngoko ke, izixhobo zidinga ukunikezelwa kwamandla ebhetri kwaye zinonyamezelo oluthile lokunciphisa inani lokugcinwa.Ukongeza, isixhobo kufuneka sibe nomsebenzi wonxibelelwano olungenazingcingo, okanye sinokuqhagamshelwa kwezinye izixhobo ukuqonda umsebenzi wonxibelelwano olungenazingcingo;
Ngaphezu koko, ngenxa yokuba izixhobo zokuhamba ezikumngxunya zinokuthi zijongane nezikhukhula ngokukhawuleza kunye nezipheleleyo ngexesha lemvula, izixhobo zidinga izinga eliphezulu lokungena kwamanzi ukuthintela umonakalo wezixhobo ezibangelwa zizikhukula, kwaye umgangatho wokungena kwamanzi uphezulu kune IP68;Xa kumiselwa ngokwemeko-bume ukuba ugxininiso lwemethane oluqhelekileyo lusondele kumda wogqabhuko-dubulo, izixhobo ezithintela uqhushumbo kufuneka ziqwalaselwe.
Izixhobo zokuqukuqela zangoku ezinokuthi zisetyenziswe kuthungelwano lokuhambisa amanzi zisekelwe ikakhulu kwindlela yomlinganiselo wokuhamba kwendawo.Esi sixhobo siguquguqukayo kufakelo kunye nokusetyenziswa, sinokuziqhelanisa okunamandla kwindawo yofakelo, kunye nokugcinwa okuphantsi.Olu hlobo lwesixhobo sokuhamba lubizwa ngokuba yi-ultrasonic Doppler flowmeter okanye i-sewer flowmeter kwimarike.
MalungaI-Doppler Flowmeter
I-Ultrasound iya kusasazwa xa idibana namasuntswana aqinileyo okanye amaqamza kwindlela yokusasaza, kubaindlela yexesha lokuhambaayisebenzi kakuhle xa kulinganiswa ulwelo olunezinto ezinjalo.Ingasetyenziselwa kuphela ukulinganisa ulwelo olucocekileyo.IIndlela yeDopplerisekelwe kwinto yokuba amaza e-ultrasonic asasazekile.Ngoko ke, indlela yeDoppler ifanelekile ukulinganisa ulwelo oluqulethe amasuntswana aqinileyo okanye amaqamza.Nangona kunjalo, ngenxa yokuba amasuntswana asasazekileyo okanye amaqamza akhona ngokungenamkhethe, ukusebenza kokuhanjiswa kwesandi kulwelo kwahlukile..
Ukongezelela, ukuba ulwelo olunentsebenzo ephantsi yokuhanjiswa kwesandi lulinganiswa, ukusasazeka kunamandla kwindawo yesantya esisezantsi kufuphi nodonga lombhobho;ngelixa ulwelo olunentsebenzo yokuhanjiswa kwesandi esilungileyo lusasazeka kwindawo yesantya esiphezulu, esenza umlinganiselo weDoppler Ukuchaneka kuphantsi.Nangona i-transducer ehambisayo kunye ne-transducer eyamkelayo yahluliwe, inokufumana kuphela ukusasazwa kwindawo ephakathi kwiprofayile yesantya sokuhamba, kodwa ukuchaneka komlinganiselo kusesezantsi kunendlela yexesha lokuhamba.
