Ukukhetha Amandla e-Cutter Suction Dredgers: I-Weichai vs Cummins-Yeyiphi eFanele ngakumbi kubuNjineli bokuDlulisa?

Njengesixhobo esingundoqo sokugrumba umlambo, ukukhutshwa kwe-silt kwizibuko kunye nokumbiwa kwegolide ye-alluvial, ii-cutter suction dredgers zisebenza phantsi kweemeko ezinzima zokusebenza ezibandakanya impembelelo yomthwalo onzima wexesha elide, ukhukuliseko lothuli kunye nokusebenza okungayekiyo. Ukukhethwa kweenjini zaselwandle kumisela ngokuthe ngqo ukuzinza kwezixhobo kunye nembuyekezo kutyalo-mali.

I-Qingzhou Jinqi Mining Machinery Co., i-Ltd. iye yakhethelwa ukugrumba kunye nezixhobo zemigodi yegolide ngaphezulu kweminyaka elishumi. Ixhaswa yi-20,000 ㎡ isiseko sokwenza kunye namava eprojekthi kumazwe angaphezu kwama-30 kwihlabathi liphela, sihlalutya iimpawu zokusebenza zeempawu zamandla eziphambili, i-Weichai kunye neCummins, ukuhambisa izisombululo zokukhetha izixhobo ezigunyazisiweyo kunye nokunceda abathengi bakhethe eyona nkqubo yamandla kwiiprojekthi zabo.

I-Weichai iinjini zedizili zaselwandle zolona phawu lucetyiswayo luphezulu kubathengi ngabakwa-Qingzhou Jinqi Mining Machinery Co., Ltd. Enesantya esiphantsi kunye ne-torque ephezulu kunye ne-torque eyaneleyo yokugcina i-torque, bayayinqanda indawo yokumisa injini ngexesha lokusikwa komhlaba olukhuni kunye nokusebenza kwesanti yokuxinana okuphezulu. Yakhelwe ngemizimba ekwazi ukumelana nokunxiba kwaye iyahambelana nepetroli ekumgangatho ophantsi, iinjini ze-Weichai zinciphisa iindleko zokuthengwa kunye nezixhobo ezisecaleni ngaphezulu kwe-20% xa kuthelekiswa neCummins. Ukuqhayisa ngothungelwano lwenkonzo eshinyeneyo emva kwentengiso kulo lonke elase-Asiya, e-Afrika naseLatin America, zilungele iiprojekthi ezinomthwalo onzima phesheya njengokugrumba imilambo kunye nokumbiwa kwegolide e-alluvial, kunye nomjikelo wokulungiswa ongaphezulu kweeyure ezingama-20,000.

Iinjini zaselwandle zaseCummins ziiyunithi ozikhethelayo ezibonelelwa yiQingzhou Jinqi Mining Machinery Co., Ltd. kwiingingqi ezinemigaqo engqongqo yokusingqongileyo. Zixhotyiswe ngeenkqubo zolawulo lwe-elektroniki ezintsonkothileyo, iinjini zaselwandle zaseCummins zibonakalisa ingxolo ephantsi kunye nemigangatho ephezulu yokuthotyelwa kokukhutshwa. Nangona kunjalo, babeka iimfuno ezingqongqo kumgangatho wamafutha kunye neemeko zokulondolozwa. Amalungu asetyenzisiweyo athatha ixesha elide ukuwafumana kwiindawo ezikude, kwaye akanawo umda wamandla owaneleyo phantsi kweemeko zokusebenza ezinomthwalo onzima. Ke ngoko, abacebisi kwiidrodi zobunjineli ezisetyenziswa kwiindawo zemigodi zaseAfrika naseMzantsi Melika.

Njengomvelisi ochwephesha wezixhobo zokucoca, iQingzhou Jinqi Mining Machinery Co., Ltd. ibambelela kwifilosofi ejolise kubathengi kwaye ibeka phambili iimeko zokusebenza zokwenyani xa ukhetha iinkqubo zamandla endaweni yokumfamekisa iinjini eziphezulu. Iiyunithi zamandla e-Weichai lukhetho lokuqala lwe-90% yeeprojekthi zokumbiwa kunye nemigodi yegolide, ukulinganisa ukuqina okugqwesileyo kunye neendleko zokusebenza komjikelo opheleleyo wobomi. Kubathengi abanohlahlo lwabiwo-mali olwaneleyo olusebenza kumazwe anemigangatho engqongqo yokusingqongileyo, sinikezela ngeeseti ezipheleleyo ezilungiselelweyo ezixhotyiswe ngeenjini zeCummins. Inkampani inikezela ngezisombululo zamandla ezihambelana kakuhle, ezisebenza ngokufanelekileyo kwizixhobo zokutsala kubathengi kwihlabathi liphela.
