Kodwa-ke, kubalulekile ukuqaphela ukuthi ukukhethwa kwethrekhi kukodwa akwenzi i-ATEX ihambisane nomshini; isitifiketi somshini wonke, isisekelo esifanele, kanye nemiklamo yesitimela esingaphansi kwemoto esimelana nenhlansi kuyadingeka kakhulu ezindaweni ze-H2. Ngaphezu kwalokho, ukuthambekela okuphakeme okungaphezu kwebanga lama-degree angu-30 kudinga amaphethini okuhamba anamandla, njengebhulokhi eligobile noma ithrekhi ye-zig-zag, ukuvimbela ukushelela lapho uthwala umthwalo ogcwele.

Imininingwane Okufanele Uyiqhathanise Ngaphambi Kokuthenga

Ngaphambi kokukhipha i-oda lokuthenga, amaqembu okuthenga kufanele aqhathanise ngokucophelela imininingwane yobuchwepheshe kunokuthembela nje ezinombolweni zemodeli ze-OEM. Ukuzulazula endaweni yemakethe engemuva kudinga ukubheka ngale kokuhambisana okuyisisekelo. Abathengi kumele bahlole ukwakheka kwangaphakathi, njengoba ukwakhiwa okuyinhloko kulawula ukumelana nobude bethrekhi kanye nobuqotho besakhiwo.

Iphethini Yokunyathela, Usayizi, Nokulingana

Ifomula yokufakwa eyisisekelo incike ezilinganisweni ezintathu ezibalulekile: ububanzi obuphelele, iphimbo (ibanga eliphakathi nendawo phakathi kwezixhumanisi zensimbi), kanye nenani eliphelele lezixhumanisi.Ubukhulu bethrekhi ye-dumperkumele ihambisane njalo namamodeli athile emishini ye-OEM kunezigaba zemishini ezijwayelekile. Ukungafani ngisho namamilimitha ambalwa ephimbeni kungabangela ukuguguleka kwe-sprocket okusheshayo kanye nokuqhekeka kwethrekhi okungenakugwenywa. Ngezansi ukuhlukaniswa okuqhathanisayo kwezincazelo ezijwayelekile ezihlolwayo lapho kufakwa izimpahla emotweni:

Ukukhetha iphethini efanele yokunyathela—njenge-C-lug yokudonsa udaka ngamandla noma i-straight-bar lug ye-hardpack—kuthonya ngqo izikhathi zomjikelezo kanye nokusetshenziswa kukaphethiloli.

Umthwalo, Ukucindezela Komhlaba, Ukudonsa, Ukushisa, kanye Nokumelana Namakhemikhali

Umthamo womthwalo kanye nomfutho womhlabathi kuxhunyaniswe ngaphakathi nokwakheka kwenhlabathi yendawo. Lapho kufakwa ama-ASV compact track loaders otshanini obuthambile noma ezindaweni ezinodaka, kudingeka iphrofayili yomfutho ophansi womhlabathi ukuze kulondolozwe ukuntanta nokuvimbela umshini ukuthi ungagcwali. Ngokuphambene nalokho, ama-track dumpers anengcindezi yomhlabathi ephezulu kakhulu uma elayishwe ngokugcwele, okudinga izintambo zensimbi eziqhubekayo ezisindayo ukuze zithwale isisindo sokusebenza esiphelele. Ukulungiswa kokucindezeleka komkhondo ofanele kuyisinyathelo esibalulekile sokusebenza ukuze kusekelwe le mithwalo esindayo ngaphandle kokuguga kusenesikhathi.

Ngaphezu kwalokho, ezindaweni ezivezwe ekushiseni okukhulu, ukuchitheka koketshezi oluyi-cryogenic, noma ukugeleza kwamakhemikhali, abaqhubi kufanele bacacise imizila eyenziwe ngamakhemikhali enjoloba akhethekile angenasici esikhundleni sezingxube eziphinde zasetshenziswa. Izindawo zokushisa okuphezulu zingonakalisa injoloba ejwayelekile, zisheshise ukuwohloka kokushisa uma izinga lokushisa lokusebenza langaphakathi lidlula imikhawulo ephephile ye-OEM ngesikhathi sokuhamba okuqhubekayo. Ngakolunye uhlangothi, ukuchayeka ku-hydrogen eyi-cryogenic kungabangela ukuqhekeka kwenjoloba okungazelelwe, okwenza ukukhetha okuhlanganisiwe okukhethekile kubaluleke kakhulu ekuphepheni kwesiza se-H2.

Indlela Yokuthola, Ukuhlola, Nokukhetha Amathrekhi

Ukuthola izindlela ezifanele zokuthengisa kudinga indlela ehlelekile yokufaneleka komthengisi kanye nokuhlolwa ngokomzimba lapho ediliva. Lezi zingxenye azikwazi ukubhekwa njengezimpahla ezijwayelekile. Ukusebenzisa inqubo yokuthenga eqinile kuqinisekisa ukuthi yonke ithrekhi efakiwe ihlangabezana nezindinganiso zokuphepha nokusebenza ezibalulekile.

Uhlu Lokuhlola Lokulinganisa Nokuthenga

Kufanele kudingeke ukuthi kuhlolwe ngokucophelela ngaphambi kokuba kufakwe noma yimuphi umzila emshinini. Okokuqala, ochwepheshe kumele baqinisekise ubukhulu obunesitembu (Ububanzi x Iphimbo x Izixhumanisi) ngokumelene ne-oda lokuthenga ukuqinisekisa ukunamathela okuqinile kokubekezelelana kwe-OEM. Okulandelayo, hlola irabha ukuze uthole amaphutha okushintshashintsha, ubheke ngokucophelela ukuqhekeka okuncane okuzungeze izixhumanisi zensimbi noma ama-drive lugs. Ukuhlolwa okuphelele kwe-durometer kuma-rubber lugs kufanele kuveze isilinganiso sokuqina phakathi kuka-60 no-65 Shore A, yize abaqhubi kumele bakhumbule ukuthi ubunzima be-Shore A buyahlukahluka ngokwesizini kanye nokushisa okuzungezile.
