I. Ukubaluleka Kokukhetha Amatyathanga NeeBhanti Ezifanelekileyo
Kwimizi-mveliso yesamente, ii-elevator zebhakethi zibalulekile ekuthuthweni kwezinto ezinzima nezirhabaxa ezifana ne-clinker, i-limestone, kunye nesamente ngokuthe nkqo.Amatyathanga ajikelezayo kunye namatyathangazinoxinzelelo olukhulu loomatshini, nto leyo eyenza uyilo lwazo kunye nolawulo lomgangatho wemveliso lube yimfuneko ukuze kuphumelele ukusebenza. Nantsi isizathu sokuba ukukhetha izinto ezifanelekileyo kubalulekile kwaye i-SCIC ijongana njani noku:
1. Umthamo wokuthwala umthwalo:Amatyathanga kunye neekhamandelakufuneka imelane nemithwalo ephezulu yokuxinana kunye neempembelelo zomothuko ezivela ekushukumeni okuqhubekayo kwebhakethi. Izinto ezingaphantsi komgangatho zibeka emngciphekweni wokungasebenzi ngequbuliso, okukhokelela ekungasebenzini kwexesha, kwiingozi zokhuseleko, kunye nokulungiswa okubiza kakhulu. Ukunamathela kwe-SCIC kwimigangatho ye-DIN kuqinisekisa ukuba iimveliso zethu ziyahlangabezana neemfuno zamandla afunekayo, njengombane ochaziweyo wokuqhekeka we-280–300 N/mm².
2. Ukumelana nokuguguleka: Indlela izinto zesamente ezirhabaxa ngayo ikhawulezisa ukuguguleka kwezinto zelifti. Iityathanga eziqiniswe ngekhephu (ukuya kuthi ga kwi-800 HV) kunye neekhaka (ukuya kuthi ga kwi-600 HV) zibonelela ngomphezulu oqinileyo ukumelana nokuguguleka, ngelixa zigcina ukuqina kwesiseko ukuthintela ukuqhekeka. Inkqubo echanekileyo ye-SCIC yokwenza i-carburizing ifezekisa ubukhulu be-10% ye-carburizing obuceliweyo kunye nobunzulu bobunzima obusebenzayo be-5-6%, ukuqinisekisa ukusebenza kwexesha elide.
3. Ukuthobela iMigangatho: Ukuthobela i-DIN 764, i-DIN 766, i-DIN 745, kunye ne-DIN 5699 kuqinisekisa ukubaimixokelelwane kunye neekhamandelaukuhlangabezana nemilinganiselo yoshishino yobukhulu, iimpawu zezinto, kunye nokuthembeka. Ubuchule be-SCIC ekuhlangabezaneni nale migangatho buqinisekisa umgangatho ohambelanayo olungiselelwe ukusetyenziswa kwemisebenzi enzima.
4. Ulawulo loMgangatho weMveliso: Ulawulo oluqinileyo lomgangatho lwe-SCIC—ukusuka ekukhetheni izinto ukuya ekuhlolweni kokugqibela—lunciphisa iziphene kwaye luqinisekisa ukuchaneka kobukhulu, ubulukhuni, kunye namandla. Olu buchule lunciphisa amathuba okusilela phantsi kweemeko ezinzima zeefektri zesamente.
Ukukhetha okulungileyoimixokelelwane kunye neekhamandelaKubalulekile ekusebenzeni kakuhle nasekukhuselekeni kwee-elevator zakho zebhakethi. Kwi-SCIC, iimveliso zethu ziyilwe kwaye zenziwe ukuhlangabezana nemigangatho engqongqo ye-DIN, ukuqinisekisa ukuba ziyakwazi ukumelana nemithwalo enzima kunye nezinto ezirhabaxa eziqhelekileyo kwiifektri zesamente. Ngolawulo lwethu oluqinileyo lomgangatho, ungathemba ukuba amatyathanga ethu kunye neekhaka ziya kubonelela ngokusebenza okuthembekileyo, kunciphisa umngcipheko wokusilela okungalindelekanga kunye neendleko zokulungisa.
II. Ukulinganisela Ubulukhuni kunye Nokuqina Ngexesha Lokwenziwa
Ukufezekisa ubunzima bomphezulu obuchazwe ngumthengi (800 HV kwiitsheyini, 600 HV kwiitshayile), ubukhulu be-carburizing (10% yobubanzi bekhonkco), ubunzulu bobunzima obusebenzayo (550 HV kwi-5–6% yobubanzi), kunye namandla okuqhawula (280–300 N/mm²) kufuna ulungelelwaniso olucokisekileyo phakathi kobunzima kunye namandla. Nantsi indlela i-SCIC efezekisa ngayo oku ngokukhetha izinto, unyango lobushushu, kunye ne-carburizing:
Iinkqubo eziphambili zokuvelisa
1. Ukhetho lwezinto:Iintsimbi ezinekhabhoni ephezulu okanye i-alloy zikhethwa ngenxa yokukwazi kwazo ukuphendula kwi-carburizing kunye nokucima, okubonelela ngobunzima bomphezulu kunye nokuqina kombindi.
2. Ukugalela iCarburizing:I-Carburizing isasaza ikhabhoni kumphezulu wentsimbi ukuze yonyuse ubulukhuni. Kwikhonkco letsheyini enobubanzi obuyi-20 mm;Ubunzulu beCarburizing: 10% ye-20 mm = 2 mm;Ubunzulu boBulukhuni obuSebenzayo: 5–6% ye-20 mm = 1–1.2 mm kwi-550 HV;Oku kudala umphezulu oqinileyo, ongenakugugiswa ngelixa kugcinwa isiseko esithambileyo ukuze sifumane imithwalo enamandla.
3. Unyango lobushushu:Ukucima: Emva kokufaka i-carburizing, izixhobo ziyacinywa ukuze zivale ubulukhuni bomphezulu (800 HV kwimixokelelwane, 600 HV kwimixokelelwane);Ukulinganisela: Ukulinganisela okulawulwayo (umz., kwi-200–250°C) kulungisa iipropati zesiseko, ukuqinisekisa ukuqina kunye namandla okuqhekeza afunekayo angama-280–300 N/mm². Ukulinganisela okugqithisileyo kunciphisa ubulukhuni, ngelixa ukunciphisa ukulinganisela kubeka emngciphekweni ububuthathaka.
4. UMthetho wokulinganisela: Ubunzima: Ubunzima obuphezulu bomphezulu bumelana nokuguguleka kwezinto ezirhabaxa;Amandla: Ukuqina kwentliziyo kuthintela ukwaphuka okubuthathaka phantsi kwemithwalo exineneyo.I-SCIC ilawula ubunzulu be-carburizing kunye neeparamitha zokulinganisa ukuze kuthintelwe ukungonakali kakhulu ngelixa ihlangabezana neemfuno zomthengi.
(iikhonkco zetsheyini ezinobunzima obuphezulu bomphezulu ofakwe ikhabhoni)
(iikhonkco zetsheyini ezinobunzima obuphezulu bomphezulu ofakwe i-carburized, emva kovavanyo lwamandla okuphuka)
Inkqubo yethu yokuvelisa ilawulwa ngononophelo ukuze kufezekiswe ulungelelwaniso olugqibeleleyo phakathi kobulukhuni kunye namandla. Ngokusebenzisa i-carburizing echanekileyo kunye nonyango lobushushu, siqinisekisa ukubaimixokelelwane kunye neekhamandelaYiba nomphezulu oqinileyo, omelana nokuguguleka ngelixa ugcina umongo oqinileyo wokusingatha imithwalo eguquguqukayo kwimisebenzi yakho. Olu lungelelwaniso lubalulekile ekwandiseni ubomi bezixhobo kunye nokuthembeka kwazo.
III. Ukuqinisekisa Ubude Bobomi Ngokusebenza Nokugcinwa
Nokuba kunjaloiitsheyini kunye neekhamandela ezikumgangatho ophezulu, ukusebenza kakuhle kunye nokugcinwa kakuhle kubalulekile ukuze kuphuculwe ubomi bee-elevator zebhakethi zefektri yesamente. I-SCIC inika abathengi esi sikhokelo silandelayo:
Izikhokelo Zokugcinwa
1. Uhlolo oluQhelekileyo:Itshekhiimixokelelwane kunye neekhamandelakwiimpawu zokuguguleka, ezinje ngokunwebeka (umz., >2–3% yobude bokuqala), ukuguqulwa, okanye ukuqhekeka komphezulu. Ukufunyanwa kwangethuba kuthintela ukungaphumeleli.
2. Ukuthambisa:Faka ii-lubricants ezishushu kakhulu nezinzima ukunciphisa ukungqubana nokuguguleka. Thambisa rhoqo emva kweeyure ezili-100-200 zokusebenza, kuxhomekeke kwiimeko.
3. Ukubeka esweni uxinzelelo:Gcina uxinzelelo olufanelekileyo lwetyathanga ukuze uphephe ukutyhafa kakhulu (okubangela ukuxhuzula) okanye ukuqina kakhulu (ukwanda kokuguguleka). Lungisa ngokweemfuno ze-SCIC.
4. Ukutshintshwa ngexesha elifanelekileyo:Buyisela izinto ezigugileyo okanye ezonakeleyo ngoko nangoko ukuze uthintele ukusilela kokuwa. Umzekelo, i-shackle egoso kufuneka itshintshwe ngokukhawuleza.
5. Iindlela ezilungileyo zokusebenza:Sebenza ngaphakathi kwemida yoyilo (umz., kuphephe ukugqithisa kakhulu ngaphaya kwamandla okuqhekeza angama-280–300 N/mm²) ukuze unciphise uxinzelelo.
Ukuze usebenzise amatyathanga akho namatyathanga kakuhle, landela le migaqo: hlola rhoqo ukuba agugile na, qinisekisa ukuthambisa ngokufanelekileyo, jonga uxinzelelo lwetyathanga, kwaye utshintshe izinto ezonakeleyo ngokukhawuleza. Ngokulandela le migaqo kwaye usebenze ngaphakathi kwemida yoyilo, unokwandisa kakhulu ukuthembeka nokusebenza kakuhle kwee-elevator zakho zebhakethi.
