Uhlelo lokulawula ugesi we-Petroleum luvame ukuhlukaniswa izigaba ezimbili, eyodwa iyimishini ye-DC (Direct Current), eyayisetshenziswa.
yokushayela imoto ye-DC, i-SCR kuphela (isilungisi sokulawula i-silicon) ngamafuphi. Esinye isisetshenziswa se-AC (Alternating Current), sona
esetshenziselwa ukushayela i-AC frequency motor, lapha ebizwa nge-VFD(Variable Frequency Drive) uhlelo.
Uhlelo lwe-SCR lwaklanywa futhi lwathuthukiswa yinkampani ye-ROSSHILL eminyakeni yamashumi ayisishiyagalombili. Imishini yokushayela iketango likawoyela kwaba
kancane kancane ithathelwe indawo yi-SCR kusukela ekusebenzeni okuzinzile nokugcinwa kalula, okuletha ukuphenduka kwe-Oil Drilling ngokugcwele.
izikhathi ezizenzakalelayo, uma ziqhathaniswa nohlelo lwamanje oluvelayo oluguquguqukayo lwamafrikhwensi, i-SCR inezinzuzo ezilandelayo
1. Ubuchwepheshe Abavuthiwe
Imishini ye-SCR ihlolwe emkhakheni wemvelo eyeqisayo futhi yenziwa kahle.
2. Easy Maintenance
I-SCR yaba khona ngaphambili, isetshenziswe endaweni ebanzi, kwezinye izinkinga ezivamile, ngokuvamile, onjiniyela abanesikhathi eside.
isipiliyoni sokusebenza singabhekana nakho, ngenxa yenkinga eyinkimbinkimbi, sidinga isisebenzi esichwepheshile sokuyixazulula.
3. Intengo Yokuncintisana
4. Izingxenye eziyisipele ziyatholakala ezifundeni eziningi, futhi zingasetshenziswa emhlabeni wonke.
I-Alternating Current electric system system iwuhlelo olusanda kuthuthukiswa lokumba i-Rig Electric Drive System eminyakeni yamuva nje.
Ithole impendulo enhle evela kumsebenzisi ngokusebenza okungcono, ukusebenza kahle okuphezulu nokusebenza okulula.Qhathanisa nayo
uhlelo lwe-SCR, uhlelo lokulawula ugesi lwe-AC lunezinzuzo ezilandelayo:
1.Motor Control Mode
Njengoba i-Siemens noma i-ABB frequency converter yamukelwa ukushayela i-Alternating Current frequency motor. Ukuba ngcono
ukusebenza ngokunemba nokuzinza, ikakhulukazi ekulawuleni iwintshi, ingaphakanyiswa kalula futhi ibekwe phansi futhi kulula ukuyisebenzisa, kakhulu
ukuhlangabezana nokusetshenziswa endaweni yokumba, okuthuthukisa ukusebenza kahle kokumba, okuphakeme kunohlelo lwe-AC.
2.Ukulawula okunembile
Uhlelo lwe-VFD oluhlanganiswe nesilawuli se-PLC kanye nomshini wokulinganisa iSpeede kufakwe uhlangothi lwemoto oluguquguqukayo.
imisebenzi yenza isilawuli semoto sizuze isilawuli se-loop evaliwe futhi Run ngokushelela, futhi isivinini sokugijima singaba
kulawulwa ngokwesidingo sangempela.
3.Hambisa umsebenzi wewintshi
I-Winch iyingxenye ebalulekile ezingxenyeni ze-rig, ngenxa yesici se-motor ngokwayo, phansi akukwazanga ukulawula.
ngemoto, kodwa ngokumiswa kwayo kanye nesistimu yamabhuleki ayisizayo ukuze ibambe iqhaza ekulawuleni.kusukela ngenqubo yokusebenza eminingi,
abanesicelo esiphezulu kumshini wokumba. Ubani onekhono ekusebenzeni kanye nekhono lokuxazulula inkinga , njengoba kukhona
ezijwayele ukwenzeka izingozi zokumba. Nokho, i-motor driven drive frequency frequency system enomsebenzi we-hover, yenza i-
iwinch ingase ime ngaphansi kokulawula ngokwenza isibambo esilawula injini yewintshi ukuthi sibuyele esimweni esiyiziro nangaphandle
omunye umsebenzi wamabhuleki asizayo. Okwenza umsebenzi wokubhola ube lula, uphephe futhi uthembeke. Umehluko wesistimu ye-DC ne-AC
ekulawulweni kwewintshi, njengomehluko wokusebenza phakathi kwemoto yegiya eshintshwayo kanye nokudlulisa okuzenzakalelayo lapho
ukusebenza imoto.
4.Ukuhlanganiswa Okuphezulu
Nge-Frequency conversion rig esetshenziswa kabanzi, ngokwezidingo zamakhasimende, ukumba nokumbiwa kanye nezimayini.
enye idatha ehlobene ingaqoqwa yi-PLC ihlanganiswe kukhompyutha yokulawula yezimboni hhayi ngethuluzi elihlukile, ngakho-ke
izindleko zingonga kakhulu futhi zinikeza lula ukufakwa, ukunyakaza nokugcinwa kwemishini.
