Ukunwetshwa kodayamitha ubuchwepheshe bokucubungula ingcindezi obusebenzisa amanzi noma izindlela zemishini ukuze kusetshenziswe amandla asuka odongeni olungaphakathi lwepayipi lensimbi ukuze kunwetshwe ipayipi lensimbi ngaphandle. Indlela yemishini ilula futhi iphumelela kakhulu kunendlela ye-hydraulic. Amapayipi amaningana athuthuke kakhulu emhlabeni anobubanzi obukhulu ngobude asetshenzisiwe enqubweni yokunwetshwa. Inqubo ithi:

Ukunwetshwa komshini kusebenzisa ibhulokhi yomkhakha ohlukanisiwe ekugcineni kwesinwebi ukuze inwebe iqonde endaweni eyi-radial ukuze ishubhu elingenalutho linyathelwe ohlangothini lobude ukuze kubonwe inqubo yokuguquguquka kwepulasitiki yawo wonke ubude beshubhu ngezigaba. Ihlukaniswe yaba izigaba ezi-5

1. Isigaba sokuqala sokuqoqa. Ibhulokhi emise okwefeni ivulwa kuze kube yilapho wonke amabhulokhi amise okwefeni athinta udonga lwangaphakathi lwepayipi lensimbi. Ngalesi sikhathi, i-radius yephoyinti ngalinye ku-tube yangaphakathi yepayipi yensimbi ngaphakathi kobude besinyathelo icishe ifane, futhi ipayipi yensimbi ekuqaleni iyindilinga.

2. Isiteji sobubanzi obujwayelekile. I-block efana ne-fan iqala ukunciphisa isivinini sokunyakaza ukusuka endaweni yangaphambili kuze kube yilapho ifinyelela endaweni edingekayo, okuyindawo yangaphakathi ye-circumferential yepayipi eqediwe edingwa yikhwalithi.

3. Isigaba sokunxeshezelwa kabusha. Ibhulokhi emise okwefeni izoqhubekela phambili yehlisa isivinini endaweni yesiteji sesi-2 ize ifike endaweni edingekayo, okuyindawo yesiyingi sangaphakathi sepayipi yensimbi ngaphambi kokubopha kabusha njengoba kudingwa idizayini yenqubo.

4. Ukubamba ingcindezi nesiteji esizinzile. Ibhulokhi yomkhakha ihlala imile isikhashana ngaphambi kokuba iphinde ikhuphuke esiyingini sangaphakathi sepayipi lensimbi. Lesi yisiteji sokugcina ingcindezi futhi sizinzile esidingwa imishini kanye nenqubo yokwandisa ububanzi.

5. Ukuthulula nokubuya esiteji. Ibhulokhi yomkhakha ihlehla ngokushesha ukusuka endaweni yesiyingi sangaphakathi sepayipi lensimbi ngaphambi kokubopha kabusha, ize ifike endaweni yokuqala yokunweba, okuwububanzi obuncane bokufinyela bebhulokhi yomkhakha edingwa inqubo yokwandisa ububanzi.

Ekusetshenzisweni okusebenzayo, inqubo yokwenza lula, izinyathelo ze-2 ne-3 zingahlanganiswa futhi zenziwe lula, ezingaphazamisi ikhwalithi yokwandisa yepayipi yensimbi.
