Uvavanyo lwe-hydrostatic ye-ductile yentsimbi

I-1. Inaliti yamanzi kumbhobho kufuneka itotshwe kancinci ukusuka kwi-downstream. Ngexesha lenaliti yamanzi, ivalve engapheliyo kufuneka isethwe phezulu kumbhobho kunye nenqanaba eliphezulu lecandelo le-pile yovavanyo lokususa igesi kumbhobho.
2. Ubude becandelo le-phumela lovavanyo lwe-hydraulic alufanele ukuba lukhulu kune-1.0km.
I-3. Umqolo wecandelo lovavanyo lovavanyo luya kuthobela kwezi zinto zilandelayo:
3.1 Umqolo kufuneka usekwe kumhlaba wokuqala okanye kumqolo wokubuyela umva, kunye namanyathelo okuqinisa kufuneka athathwe xa umhlaba uthambile;
3.2 Udonga lwasemva luya kuba liflethi kwaye luvela kwi-axis yombhobho.
4. La malungiselelo alandelayo aya kufezekiswa phambi kovavanyo lwe-hydrostatic:
4.1 Ukufakwa kombhobho kunye nokubuyisa umva kwemingxunya kuya kuhlangabezana neemfuno zenkcazo;
4.2 Iinkxaso zenkxaso kunye namancedo e-anchorage yemibhobho ufikelele kumandla oyilo; Izixhobo zombhobho ngaphandle kokuba isebe pirs kunye nezixhobo ze-anchorage ziya komelezwa;
4.3 Zonke izinto ezivulekileyo zovavanyo lwepayipile ziya kufakwa ngokungqongqo, kwaye akukho thuba lamanzi liya kuvunyelwa;
4.4 I-valve yesango ayiyi kusetyenziswa njengebhodi yokubhloka yovavanyo, kwaye ayiyi kuba ne-hydrant yomlilo, i-hammer yokutsala amanzi, ivali yokhuseleko kunye nezinye izinto;
4.5 I-Wordritor kwipayiphu iya kususwa ngaphambi kovavanyo lwe-hydraulic.
5. Emva kokuba icandelo le-pile lovavanyo lizaliswe ngamanzi, kucetyiswa ukuba kuqhutyeke uvavanyo lwe-hydraulic ukuba lube nzima phantsi koxinzelelo lokusebenza, kwaye ixesha elinzima lingaphezulu kweeyure ezingama-24.
6. Uxinzelelo lovavanyo
Uxinzelelo lokusebenza yi-0.5MPA, kunye noxinzelelo lovavanyo ngamaxesha angama-2.0 oxinzelelo lokusebenza;
Working pressure is>I-0.5MPA, kunye noxinzelelo lovavanyo luxinzelelo lokusebenza kunye ne-0.5MPA.
7. Indlela yovavanyo
7.1 Inqanaba lokuvavanya kwangaphambili: Phakamisa uxinzelelo lwamanzi kumbhobho kancinci kuxinzelelo lovavanyo lwe-30min. Ngexesha, gcwalisa uxinzelelo, kodwa ungaphezulu kunengcinezelo yovavanyo; Jonga ukuvuza kunye nomonakalo kumbonakalo ye-pipe kunye nezixhobo; Xa amanzi evuza kunye nomonakalo, yeka uvavanyo loxinzelelo ngexesha kwaye ubone isizathu kwaye uthathe amanyathelo ahambelanayo.
7.2 Inqanaba lovavanyo oluphambili: Emva kokuyeka inaliti yamanzi kunye noxinzelelo, ukuzinzisa ii-15min; Xa uxinzelelo lwehla emva kokuba i-15min lingadluli kwi-0.03MPA, uxinzelelo lovavanyo luncitshisiwe luxinzelelo lokusebenza kwe-30min. Ukuba akukho mvuwulweyo, uvavanyo lwe-hydraulic lufanelekile.
8. Ukwamkelwa kovavanyo lwe-hydraulic
Kwindlela yokugcina isiqinisekiso sokugqibela, ukulinganiswa kwamanzi okulinganiswa kuya kuba ngaphantsi okanye ukulingana nexabiso elivumelekileyo elichazwe kwitafile elandelayo nakwixabiso elivumelekileyo elichazwe kwifomula elandelayo:
