I-LAC-China yorhwebo yorhwebo yayiphantse yazinza ngokugqibeleleyo ngo-2020. Oku kuyaphawuleka ngokwayo, njengoko i-LAC GDP yehle ngaphezu kwe-7 pesenti ngo-2020 ngokoqikelelo lwe-IMF, ilahlekelwa ukukhula kweshumi leminyaka., kunye nokuthunyelwa kwemveliso yengingqi kwehle iyonke (iZizwe eziManyeneyo ngo-2021).Nangona kunjalo, ngenxa yorhwebo oluzinzileyo ne-China phakathi kokuwohloka koqoqosho olunjalo, ukuhamba korhwebo lwe-LAC kunye ne-China kukhule ukuya kumanqanaba arekhodiweyo e-GDP yengingqi.
Ukuthunyelwa kwempahla ye-LAC ukuya e-China kunyuke kancinane ukusuka kwi-135.2 yeebhiliyoni zeedola ukuya kuqikelelo lwe-135.6 yeebhiliyoni zeedola, kwaye ukuthunyelwa kwemveliso yaseTshayina kwi-LAC kwehle kancinane ukusuka kwi-161.3 yeebhiliyoni zeedola ukuya kwi-135.6 yeebhiliyoni zeedola.$ 160.0 billion.Kodwa njengoko i-GDP yengingqi ye-LAC yehla ngokumangalisayo, zombini izinto ezithunyelwa ngaphandle kunye nokuthunyelwa ngaphandle ziye zanda kakhulu njengepesenti ye-GDP, kwaye ibhalansi ikhule kancinane, ukusuka kwi-0.5% ukuya kwi-0.6% ye-GDP yommandla.
Urhwebo kusenokwenzeka ukuba lubone isiphumo sokungaguquguquki okuqhubekayo kumaxabiso esinyithi njengoko uqoqosho lwehlabathi lusiya luphucuka kwaye nefuthe lenkuthazo yase-China kulwakhiwo liyehla.Nangona amaxabiso entsimbi enyuke ngo-2020, iYunithi yezoBugcisa kwezoQoqosho kunye neBhanki yeHlabathi zilindele ukuba ixabiso lentsimbi liwe kwakhona kwiminyaka ezayo, ngelixa imbonakalo yobhedu inethemba ngandlel’ ithile.Ezi ziindaba ezimnandi zokuthunyelwa ngaphandle kweemveliso zoomatshini bemigodi ukusuka eTshayina ukuya eLatin America, ngakumbi izixhobo zokomba.Inkampani yethu iHebei Gimarpal Machinery Technology Co., Ltd. ikhethekileyo ekuveliseni nasekuthumeleni kwamanye amazwe izixhobo zokomba imigodi ezinomzi-mveliso owakhe, onje ngetaper bar, i-threaded bar, i-chisel bit, iqhosha elincinci.Ke ngoko, i-2021 iya kuba lithuba elitsha.
Umatshini wamandla osezantsi wevolumetric umngxuma oqhubekayo, obizwa ngokuba yi-screw drill.I-screw drill, esebenzisa udaka kunye namanzi acocekileyo njengesixhobo sombane, ithuthwa ukuya ezantsi komngxuma ngomngxuma osembindini wentonga ye-drill, kwaye ngokusisiseko sisixhobo sokuguqula amandla esiguqula amandla oxinzelelo lolwelo lube ngamandla omatshini. .Ngexesha lokugaya, i-screw drill iqhuba ngokuthe ngqo ityhubhu engundoqo kunye ne-drill bit edibeneyo kwi-shaft drive ephantsi komngxuma ukujikeleza.I-drill string yonke isetyenziswe kuphela njengendlela yokuhambisa i-high-pressure medium medium kunye nentonga exhasa i-counter torque ye-drill bit, kwaye ayijikelezi.Xa kuthelekiswa nokugrumba okuqhelekileyo, i-screw drilling ineengenelo ezininzi, ezinje ngokuncipha kakhulu ukunxitywa kwentonga ye-drill kunye nesantya esiphezulu sokomba.Isona sixhobo esiphambili sokubhoboza imingxuma yokuqondisa kwaye uye wadlala indima kwintsimi yokubhoboza.
Kwi-1955, i-United States Christensen Mine Drilling Products Company yaqala uphando olusekelwe kumgaqo we-Moinuo, kwaye yaba ngowokuqala ukuphumelela ngo-1964, ogama lingu "Dana Drill";iSoviet Union yafunda ngempumelelo “convex” screw drill ekuqaleni kweminyaka yoo-1970;ETshayina Iziko loPhando lobuChwephesha loHlolo lweSebe lezeMigodi liphuhlise ngempumelelo i-screw drills ekuqaleni koo-1980.Amazwe avelise i-screw drills ukuza kuthi ga ngoku aquka iMelika, iRussia, iChina, kunye neJamani.
