I-PU noma i-Nylon noma i-Rubber noma i-TPR? Ukukhetha Impahla Efanele Yesondo Le-Caster
Kwadalwa ngo 10.13
Umbuzo uza cishe kuyo yonke imibuzo yesibili, futhi uza ngendlela efanayo. Umthengi usevele eqinisekisile usayizi kanye nesilinganiso somthwalo, bese ebuza ingxenye yokugcina: i-PU noma i-nylon?
Umbuzo ofanele ukuwubuza, ngoba into esetshenziswayo iyona enquma ukuthi i-caster iziphatha kanjani phansi kwakho. Hhayi isibalo somthwalo. Isondo elingu-200 mm elilinganiselwe ku-250 kg lizogingqika kahle kwenye imboni kodwa libe yisikhalo esilindile kwenye, kumthwalo ofanayo, ngaphandle kokushintsha ngaphandle kwento esetshenziswayo yesondo.
Sizenza zonke, ngakho asinayo intandokazi esiyicindezelayo. Nakhu esikuchaza kubathengi mayelana nokukhetha.
Ingxenye eqinile ithwala umthwalo. Ithayi yenza konke okunye
Ama-caster amaningi akhiwe ngendlela efanayo. Into eqinile ithwala umthwalo futhi ibambe i-bearing, kanti ithayi ethambile ihlezi ngaphandle futhi ithinta phansi.
Le ngxenye eqinile ngokuvamile i-polypropylene, i-iron noma i-aluminium. Kwamanye amasondo awekho ithayi ehlukile: isondo lonke liyingxenye eyodwa yento eqinile, yingakho amasondo aqinile e-PP ne-nylon eziphatha ngendlela ehluke kakhulu kunerabha noma i-PU.
Kunezinto ezimbili ezilandelayo kulokho. Okokuqala, isilinganiso somthwalo sichaza ukwakhiwa konke, umongo, ibheringi engemuva kwawo kanye nenhlanganisela yenjoloba esekuqaleni kwawo, hhayi ukugibela. Okwesibili, konke umsebenzisi akubonayo, umsindo, umzamo wokusunduza, izimpawu phansi, ukuguga, kuvela entweni engaphandle.
Uhla lwethu lwalo lubonisa ukuthi kungani ungeke wahlulela isondo ngesayizi yalo. Isondo elingu-200 mm lingalinganiselwa ku-210 kg, 330 kg noma 500 kg. Phakathi kwalezi zintathu umongo uyashintsha, inhlanganisela yenjoloba iyashintsha kanye nebheringi iyashintsha, zontathu kanyekanye. Ngakho-ke ungadlulisi isibalo somthwalo usuka esondweni elibukeka lifana nje. Ububanzi obufanayo akusho umsebenzi ofanayo.
Injoloba: ithule, iyabamba, futhi ayilimazi phansi
Injoloba esekuqaleni kwe-polypropylene noma i-iron iyinhlanganisela esiyicaphunayo kakhulu emsebenzini wangaphandle nasemaphethelweni omgwaqo, futhi ngesizathu esihle. Ibamba indlela emanzi, ihamba ngokuthula, futhi ayimaki phansi. Ekusetshenzisweni okujwayelekile iguga kahle.
Into eyodwa okufanele uyiqaphele ukugqama okucaba. I-caster emile ilayishwe endaweni efanayo izinyanga ezingaphezulu ingathatha indawo egqamile ethayini. Emzileni lapho isondo lihlala liphenduka, lokho akwenzeki.
Khetha irabha uma phansi bushelelezi noma bumahhadlahhadla ngokulingene, uma umsindo ubalulekile, futhi uma ukubamba nokuhamba buthule kubaluleke kakhulu kuwe kunentengo ephansi kakhulu.
TPR: umuzwa ofanayo ngenani elincane, ngaphakathi endlini
I-TPR iziphatha cishe njengerabha futhi ibiza kancane, yingakho idume kuma-caster asebenza ngokulula nangokulingene.
Akusiyo nje irabha eshibhile. Uma iqhathaniswa nerabha ayithandi ukushisa okuqhubekayo kanye nokulayisha okugxilile. I-TPR ithola indawo yayo ngaphakathi endlini, kuma-trolley nasemishinini elula, lapho umthwalo ulingene futhi indawo ihlanzekile futhi yomile.
I-PP ne-nylon (PA): amasondo aqinile
I-Polypropylene ne-nylon yizinto ezimbili eziqinile esizisebenzisa kakhulu, futhi zisezingeni elihlukile lamanani.
I-PP iyona eshibhile kulezi zimbili. Ilula, ayimaki phansi, futhi ibhekana nesisindo esimaphakathi ngaphakathi endlini. Engayithathi kahle ukuguguleka nokushayeka. Emhlabathini omangelengele isondo le-PP liguga ngokushesha, futhi ukuwa okunzima kungalidabula. Ingokwemishini elula nephakathi nendawo esetshenziswa ngaphakathi endlini.
I-Nylon (PA) inzima kune-PP futhi imelana nokuguga kakhulu. Ithwala umthwalo omkhulu ngobubanzi obufanayo, imelana namafutha namakhemikhali, futhi igingqika ngokumelana okuncane kakhulu phansi okubushelelezi.
I-MC nylon iyigredidi ehlukile, hhayi elinye igama elisho i-nylon. Iyacwiywa esikhundleni sokukhishwa nge-extrusion, futhi siyisebenzisa kuphela emasondweni asindayo kakhulu, lapho umthwalo nomthelela kudlula lokho isondo le-nylon elijwayelekile elingakwazi ukukuthwala. Emsebenzini ojwayelekile, i-nylon ejwayelekile iyimpendulo efanele, futhi ishibhile.
Into i-nylon engayenzi ukumunca noma yini. Idlulisela umthelela ngqo emthwalweni kanye nebracket, inomsindo ezindaweni eziqinile, futhi ezindaweni ezithambile ingashiya amamaki okungeyona i-rubber noma i-PU engawashiya.
I-cast iron: yokushisa kanye nemithwalo esindayo kakhulu
Amasondo e-cast iron awokuhhavini, izindawo zokuncibilikisa insimbi kanye neziko. Athatha ukushisa okungacekela phansi zonke ezinye izinto ezisetshenziswayo ezikuleli khasi, futhi athwala imithwalo emikhulu.
Futhi asindayo, futhi angalimaza indawo ethambile. Uma umsebenzi wakho ungabandakanyi ukushisa noma umthwalo owedlulele, i-cast iron ngokuvamile iyimpendulo engalungile.
I-PU: elula kakhulu ukuyiphushela, futhi inomthwalo omkhulu nge-diameter ngayinye
I-polyurethane igingqika kalula kune-rubber ne-TPR, futhi ithwala isisindo esiningi nge-diameter efanayo yesondo. Yingakho ivela emishinini esindayo kanye kunoma yini ephushwa ibanga elide.
Iphinde imelane namafutha, igrisi nokuguguleka kahle, futhi ayishiyi uphawu ezindaweni eziningi zaphansi. Ngokuhlangenye kwethu ikhiqiza izikhalo ezimbalwa kakhulu ezindaweni zaphansi zemboni ezixubile.
Kunemikhawulo emibili okufanele uyazi. Ngaphansi cishe kuka--10 °C iyaqina futhi iyeke ukuba yikhetho elisongayo kalula. Futhi ezimweni ezishisayo nezimanzi unomphela, amanye amazinga e-PU azohlakazeka ngokuhamba kwesikhathi, ngakho izinga libalulekile njengoba negama lezinto. Uma umthengi esitshela ukuthi isondo lizohlala endaweni yokugeza, sibuza ngezinga lokushisa namakhemikhali ngaphambi kokuba sinikeze intengo.
Uphansi yisicaciso sangempela
Uma umthengi ethumela umthwalo nobubanzi kodwa engathumeli uphansi, sicela isithombe. Uphansi lunquma okuningi kunedatha yeshidi.

Izindawo ezimbili, inombolo yengxenye eyodwa
Iphutha elibizayo akukhona ukukhetha into engalungile. Ukusebenzisa into eyodwa emisebenzini emibili.
Iphansi lesuphamakethe nendawo yokwakha kubukeka kufana ku-oda lokuthenga, ngoba yomibili imigqa ifundeka u-200 mm futhi yomibili ifundeka umthwalo ofanayo. Beka isondo elifanayo kuzo zombili, futhi elinye kulawa mabili lizobuya njengesikhalo phakathi nonyaka. Ephansi elibushelelezi isondo eliqinile liyabhonga futhi limaka amathayela. Egravelini isondo elithambile ligugile.
Uma uthengela izindawo ezingaphezu kweyodwa, hlukanisa umugqa. Izinombolo zezingxenye ezimbili zikubiza kancane ngokuphatha. Isikhalo sasensimini sikubiza i-akhawunti.
Esikuhlolayo ngaphambi kokuthi iqoqo lihanjiswe
Izimangalo ngezinto zokusetshenziswa kulula ukuzenza, ngakho-ke siyahlola esikhundleni sokuchaza. Yonke into ihamba ngokuhlolwa komthwalo oshintshayo ngaphambi kokuba ishiye imboni, futhi amabrakethi ahamba ngokuhlolwa kwe-salt spray egumbini lethu. Amasondo ethu emigqomo yemfucuza engu-200 mm nawo anesitifiketi sokuhambisana ne-GTS esihamba kuze kufike kuNhlaba 2028, futhi siyasiqinisekisa njalo.
Uma imakethe yakho ingeyaseYurophu futhi uhlinzeka ngamabhokisi ahambayo, phakamisa i-EN 840 esigabeni sokubuza. Ama-castor ayingxenye yalokho okuhlolwa ngokumelene nalelo zinga, futhi umhlinzeki owazi lelo zinga uzokukhipha ngaphambi kwakho.
Okufanele usithumelele kona
Thumela lezi zinombolo eziyisithupha ezifanayo esizicela kubo bonke abathengi, futhi uzothola impendulo esebenzisekayo ngokushesha. Usayizi wemishini noma wesitsha. Isisindo lapho kulayishiwe. Ububanzi besondo. Ibanga lezimbobo zebhawudi noma usayizi wepuleti. Indawo ehamba kuyo. Inani lonyaka.
Umbuzo ngempahla, engeza isithombe esisodwa saphansi. Sisitshela okuningi kunedatha yephepha: amathayela abushelelezi, ukhonkolo oluvaliwe, i-aggregate eveziwe, itshe, imisele kanye nezinsika. Uma indawo ibalulekile, shono futhi, noma ngabe ukuhlanza, izinga lokushisa, amakhemikhali noma ukugcinwa kwangaphandle.
Ngalokho, singaphendula umbuzo owawuwubuze ngempela. Hhayi nje ukuthi yiluphi usayizi, kodwa yiluphi uhlobo lwento kanye naluphi umgogodla.
I-Zhongshan VIMA Metal Products yenza amasondo e-caster emikhunjini yemfucuza, imishini yezimboni, ifenisha, izicelo zensimbi engagqwali kanye nemishini yezokwelapha e-Zhongshan, e-Guangdong kusukela ngo-2007. Sithumele izinombolo ezi-6 kanye nesithombe saphansi, futhi sizobuya nencazelo kanye nesampula.
