    Imibhobho yeSshawzenziwe ngeekhoyili zensimbi, njengezixhobo eziluhlaza, zikhutshiwe kwiqondo lokushisa rhoqo, kwaye lidlwengulwe yinkqubo ye-Arc ye-Arc ePhezulu. Itekhnoloji yemveliso yokuqinisekisa iqinisekisa ukuya kumanqanaba aphezulu okuchaneka kunye nokuqina, esenza imibhobho yethu ilungele imithwalo ye-subwaters.

    Umbhobho womgca wamanzi angaphantsi komhlaba

    Intliziyo Yokuumbhobho wentsimbiyindawo yayo eyahlukileyo yoyilo. Intsimbi yentsimbi ityalwe kwisixhobo se-welding phumela kwaye ngokuthe ngcembe saqengqeleka nge-rollers ezininzi ukwenza ityhubhu ejikelezayo ingenanto yomqala wokuvula. Inokwazi ukuhlengahlengisa isixa semali yokuphuma kwe-roller, kwaye i-Wold Gap inokulawulwa phakathi kwe-1-3mm ukuqinisekisa unxibelelwano olungenamthungo nolomeleleyo. Ukongeza, zombini iziphelo ze-widd idibeneyo zigungxula ngokugqibeleleyo, zibonelela ngokugqibeleleyo.

    Imibhobho yensimbi ye-SSAW ineempawu ezininzi ezahlulahlula kwimibhobho yentsimbi yendabuko. Isakhiwo sayo seSpiral sinamandla amakhulu kunye nokuxhathisa kumakhosi angaphandle, aqinisekisa ukhuseleko kunye nokuthembeka kwenkqubo yokuhanjiswa kwamanzi. Ukongeza, inkqubo ephezulu ye-welding iqinisekisa ukuba amalungu avuza-bobungqina kwaye athintele iphepha lokubonisa amanzi okanye ungcoliseko. Ngolwazi oluqinileyo nolwakhiwo olunamandla kunye nonxibelelwano olukhuselekileyo, lo mbhobho uqinisekisa ukusebenza okungapheliyo kwaye unciphise iimfuno zesondlo, esenza isisombululo esisebenzayo sayo nayiphi na iprojekthi yamanzi aphantsi komhlaba.

    a. Indlela ye-Deaxotion ichongwe ngolu hlobo lulandelayo:

    I-FF: Intsimbi egcinwe ngokupheleleyo i-nitrogen ebophelelayo kwizixa ezaneleyo zokubopha initrogen (umz. I-0,020% ye-al).

    b. Elona xabiso liphezulu le-nitrogen alisebenzi ukuba ukubekwa kwekhemikhali kubonisa i-0,020% ye-al / n i-2: 1, okanye ukuba izinto ezaneleyo ze-N-Bing zikhona. Izinto ezibophelelayo ziya kurekhodwa kuxwebhu lovavanyo.

    Le mveliso ikhethekileyo yenzelwe ukudibana neemfuno ezahlukeneyo zeshishini. Enoba ulwakhiwo lokuhambisa amanzi kamasipala kunye neenkqubo zothutho lwe-wibage okanye ukuthutha igesi yendalo kunye neoyile kwi-oyile emide, imibhobho ye-ARC ye-PARP ye-SPREAD ilukhetho lukhetho lokuqala. Ukomelela kwexeshana kuye kufuneke kwiinkqubo zepile zombhobho, ukubonelela ngozinzo olungenazinzo olungenakuthelekiswa nanto kunye nomthwalo. Ngamandla abo aphezulu kunye nokuthembeka, imibhobho yethu idlula lonke ulindelo ngokwezenzo zokusebenza kunye nobomi obude.
