Umbuzo 8: Ngaba kufuneka nditshintshe i-sprocket xa nditshintsha i-track chain?

Ewe. Xa utshintsha itshaneli yomkhondo, soloko uhlola kwaye mhlawumbi utshintshe ii-sprockets ukuze ubone ukuba zigugile kangakanani. Ukufaka itshaneli entsha kwi-sprocket egugileyo kuya kukhawulezisa ukuguguleka kwetshaneli yomtya.

Umbuzo 9: Lingakanani ixesha elifunekayo kwiiodolo zevolumu ze-EX300 sprockets?

Amaxesha okukhokela kwiiodolo zevolumu zee-sprockets zeHitachi EX300 zihlala ziqala kwiintsuku ezisi-7 ukuya kwezingama-30 kuxhomekeke kumthamo weodolo kunye nendawo ekuyiwa kuyo, kunye nokukwazi ukubonelela ngeziqwenga ezifikelela kwi-10,000 ngenyanga.

Umbuzo 10: Yeyiphi i-torque ekufuneka isetyenziswe kwiibholiti zokufaka ii-sprocket?

Kwii-sprockets ze-EX300-class drive, ii-bolts zokufaka (eziqhele ukuba yi-grade 10.9) kufuneka zi-torque zibe yi-1,000–1,100 Nm (738–811 lb-ft) kwipateni edibeneyo, enamanqanaba amathathu kusetyenziswa i-torque wrench elinganisiweyo.

11. Isiphelo

Iindibano ezintathu ze-Hitachi OEM cross-reference drive sprocket ezibhalwe kolu hlalutyo—1022168, 71471228, kunye ne-AT202586—zimele izinto ezibalulekileyo zokuhambisa amandla kwi-EX300-1, EX300-2, kunye ne-EX300-3 series hydraulic crawler excavators ezisetyenziswa kwimigodi, ekumbeni, nakwimisebenzi yokwakha enzima kwihlabathi liphela. Njengenxalenye ephambili esebenzayo kwinkqubo ye-undercarriage, i-sprocket iguqula i-torque yokujikeleza ye-final drive motor ibe yi-linear pulling force eqhuba umatshini, nto leyo eyenza ubuchwephesha bayo bube sisiseko sokuhamba komatshini kunye nemveliso yokusebenza.

I-CQC TRACK (i-HELI MACHINERY MANUFACTURING CO., LTD.) yenza ezi sprockets ukuze zihlangabezane okanye zidlule kwiimfuno ze-OEM ngokusebenzisa i-advanced closed-die hot precision forging, i-precision CNC machining, i-computer-controlled computer heat treatment, kunye ne-strigo quality authentication protocols. Iinkqubo zokuvelisa eziqinisekisiweyo ze-ISO 9001:2015 zenkampani, ii-complete test protocols, kunye ne-strategic position njengenye yeenkampani ezintathu eziphezulu ezivelisa izinto ezingaphantsi kwesithuthi kwiqela le-heavy machinery industry eQuanzhou zivumela ukunikezelwa rhoqo kwiimarike zemigodi zehlabathi.

Kwabasebenzi bemigodi, abathengisi bezixhobo, kunye nabasasazi bezixhobo kulo lonke elaseMzantsi Melika (eBrazil, eChile, ePeru), eOstreliya (ePilbara, eQueensland, eNew South Wales), eYurophu (eJamani, eFransi, eScandinavia), naseRashiya/eAsia Ephakathi (eSiberia, eKazakhstan, eMongolia), ezi sprockets zibonelela ngenye indlela ethembekileyo nengabizi kakhulu kwiindawo ze-OEM ngaphandle kokubeka emngciphekweni umgangatho wezinto, ukuchaneka kokwenziwa, okanye ubomi benkonzo.

Iingcali zokuthenga ziyakhuthazwa ukuba ziqinisekise ukuhambelana kwazo zisebenzisa amanani e-OEM anikezelweyo, zicele amaxwebhu asemgangathweni aquka iziqinisekiso zezinto kunye neengxelo zokuhlolwa okulinganayo, kwaye ziseke ubudlelwane obuthe ngqo nobonelelo lwazo kunye nabavelisi abakhethekileyo ukuze kuphuculwe iindleko zizonke zobunini beemoto ezingaphantsi kwe-Hitachi EX300-1/2/3. Kubaphathi beenqwelo-mafutha kunye nabaphathi bolondolozo, ukusebenzisa ishedyuli yokuhlola i-sprocket kunye nokutshintshwa kwayo—kubandakanya ukulinganisa ukuguguleka kwamazinyo rhoqo, ukuqinisekiswa kwe-bolt torque, kunye nokutshintshwa kwe-sprocket kunye ne-chain edibeneyo—kumela icebo elisebenzayo lokwandisa ubomi benkqubo yemoto engaphantsi kwe-carriage kunye nokunciphisa ixesha lokungasebenzi elingalindelekanga.

Olu shicilelo lobuchwephesha lujoliswe kwiingcali zobunjineli kunye nokuthengwa kwempahla kwimizi-mveliso yezemigodi kunye neyokwakha enzima. Zonke iinkcukacha zixhomekeke ekuqinisekisweni kwamaxwebhu e-OEM akhoyo. Ukuze ufumane amaxabiso angoku, amaxesha okukhokela, kunye nenkxaso yobugcisa, nxibelelana ne-CQC TRACK ngqo.
