Uhwebo lwempahla ye-LAC-China lwalucishe luzinze ngokuphelele ngo-2020. Lokhu kuyaphawuleka ngokwakho, njengoba i-LAC GDP yehle ngamaphesenti angaphezu kuka-7 ngo-2020 ngokwezilinganiso ze-IMF, yalahlekelwa ukukhula ngeminyaka eyishumi., nokuthunyelwa kwempahla yesifunda kwehle kukonke (United Nations 2021).Kodwa-ke, ngenxa yohwebo oluzinzile neShayina phakathi nokuwohloka komnotho okuwohlokayo, ukuhwebelana kwempahla ye-LAC neChina kwakhula kwafinyelela amazinga aqophayo e-GDP yesifunda.
Ukuthunyelwa kwempahla ye-LAC eChina kukhuphuke kancane kusuka ku-$135.2 billion kuya ku-$135.6 billion, kanti ukuthunyelwa kwezimpahla zaseChina ku-LAC kwehle kancane kusuka ku-$161.3 billion kuya ku-$135.6 billion.$ 160.0 billion.Kodwa njengoba i-GDP yesifunda ye-LAC yehla kakhulu, kokubili ukungenisa kanye nokuthunyelwa kwamanye amazwe kukhuphuke kakhulu njengephesenti le-GDP, futhi ibhalansi yakhula kancane, isuka ku-0.5% yaya ku-0.6% ye-GDP yesifunda.
Uhwebo kungenzeka luwubone umthelela wokuntengantenga okuqhubekayo kwamanani entengo yensimbi njengoba umnotho womhlaba usimama kanye nomphumela wokugqugquzelwa kweChina ekwakhiweni uncipha.Nakuba izintengo zensimbi zenyuka ngo-2020, i-Economist Intelligence Unit kanye neBhange Lomhlaba balindele ukuthi intengo ye-ayoni izokwehla futhi eminyakeni ezayo, kuyilapho umbono wethusi ubonakala unethemba elikhulu.Lezi yizindaba ezinhle zokuthunyelwa ngaphandle kwemikhiqizo yemishini yezimayini isuka e-China iye e-Latin America, ikakhulukazi imishini yokumba.Inkampani yethu i-Hebei Gimarpal Machinery Technology Co., Ltd. ikhethekile ekukhiqizeni nasekuthumeleni amathuluzi okumba izimayini anefektri yayo, njenge-taper bar, i-threaded bar, i-chisel bit, inkinobho yenkinobho.Ngakho-ke, i-2021 izoba yithuba elisha.
Umshini wamandla ongaphansi wembobo yevolumu eqhubekayo, obizwa ngokuthi i-screw drill.I-screw drill, esebenzisa udaka namanzi ahlanzekile njengendawo yamandla, ithuthwa iye phansi embobeni ngembobo emaphakathi ye-drill rod, futhi empeleni iyithuluzi lokuguqula amandla eliguqula amandla okucindezela oketshezi abe amandla omshini. .Ngesikhathi sokubhola, i-screw drill ishayela ngokuqondile ishubhu ewumgogodla kanye ne-drill bit exhunywe ku-shaft yokushayela phansi kwembobo ukuze ijikeleze.Yonke intambo yokubhoboza isetshenziswa kuphela njengeshaneli yokudlulisa i-high-pressure medium kanye nenduku esekela i-counter torque ye-drill bit, futhi ayizungezi.Uma kuqhathaniswa nokubhola okuvamile, ukubhola ngezikulufu kunezinzuzo eziningi, njengokuncishiswa kakhulu kwenduku yokubhoboza kanye nesivinini esikhulu sokubhola.Iyithuluzi eliyinhloko lokumba izimbobo eziqondisayo futhi libambe iqhaza emkhakheni wokumba.
Ngo-1955, i-United States Christensen Mine Drilling Products Company yaqala ucwaningo olusekelwe kumgomo we-Moinuo, futhi kwaba ngeyokuqala ukuphumelela ngo-1964, ebizwa ngokuthi "Dana Drill";iSoviet Union yafunda ngempumelelo “i-convex” screw drill ekuqaleni kwawo-1970;I-China I-Exploration Technology Research Institute yoMnyango Wezimayini ithuthukise ngempumelelo imishini yokumba izikulufu ekuqaleni kwawo-1980.Amazwe asekhiqize ama-screw drill kuze kube manje ahlanganisa i-United States, i-Russia, i-China, ne-Germany.
