Izimpawu kanye nezinzuzo zeamarola we-polyethylene anesisindo esiphezulu se-molecular
I-roller iyingxenye ebalulekile nengxenye esengozini yemishini yokudlulisa, futhi ikhwalithi yayo inquma ngokuqondile impilo yesevisi yemishini yokuthutha kanye nokuthi idla amandla angakanani.Amarola wemishini yokudlulisaesetshenziswa njengamanje ezweni lakithi ikakhulukazi zisebenzisa amarola ensimbi.Uma kuqhathaniswa nama-roller emikhiqizo efanayo yangaphandle, kukhona ukushiyeka okufana nokuphila okufushane kwesevisi, i-coefficient enkulu yokumelana nokusebenza, nesisindo esikhulu sama-roller.Ngaphezu kwalokho, imikhiqizo ejwayelekile ye-roller yensimbi ifaneleka kuphela izikhathi zokukhiqiza ezijwayelekile.Ezimayini ezinezidingo eziphakeme zomsindo nogesi ongaguquki, izitshalo zokuphekela ezonakalisayo, izinkampani zamakhemikhali, neminye imisebenzi ekhethekile, ubude besicelo yizinyanga eziyisi-6, esifushane Inyanga eyodwa ilethe imikhawulo emikhulu kanye nezingozi ekukhiqizeni imishini yokuthutha.Izingozi zokuphepha zenzeke ngokuphindaphindiwe, okuholela ekulahlekelweni okukhulu kanye nokusetshenziswa okuphezulu kwamandla.Uma kubhekwa inani elikhulu lama-roller asetshenzisiwe kanye nokusetshenziswa okukhulu kwamandla, ukuguqulwa kwama-roller ensimbi yendabuko kwashisa amashiya.Ngokusekelwe kulokhu, sakha amarola we-polyethylene anesisindo esiphezulu se-molecular esekelwe esimweni samanje samakhono asekhaya nawangaphandle, ngesisekelo samarola ensimbi avamile, nangokusungula amakhono, isakhiwo, kanye nemishini yokusebenza.
1. Irola yedatha ye-UHMWPE
I-polyethylene enesisindo samangqamuzana esingaphezu kwezigidi ezingu-1.5 ibizwa ngokuthi "UHMW-PE", esetshenziswa njengepulasitiki yobunjiniyela ngenxa yemisebenzi yayo emihle kakhulu yomzimba.Lapho sikhetha izinto zokusetshenziswa, siqale sicabangele imisebenzi elandelayo emihle kakhulu yohlelo lokusebenza:
(1) Ukumelana nokugqoka Ukumelana nokugqokwa kwe-UHMWPE kuqala phakathi kwamapulasitiki futhi kudlule izinsimbi ezithile.Ukumelana nokugqoka okuphezulu okunjalo kwenza kube nzima ukuhlola ukumelana kwayo nokugqokwa ngezindlela ezijwayelekile zokuhlola ukugqokwa kwepulasitiki.Ngakho-ke, ukugqoka kodaka kukhethiwe.Emishini yokuhlola, ukumelana nokugqoka kuhambisana nesisindo samangqamuzana, njengoba isisindo samangqamuzana sikhula, ukumelana nokugqoka kuzoba ngcono;
(2) Ukumelana nomthelela kanye nokumuncwa kwamandla okunomthelela.Kunzima ukuphuka kanye nokulimala ngezindlela zokuhlola umthelela ojwayelekile.Amandla ayo omthelela akhula ngokukhula kwesisindo samangqamuzana, afinyelele phezulu lapho isisindo samangqamuzana siyizigidi ezingu-1.5, bese siqhubeka nokukhula ngesisindo samangqamuzana.Futhi kancane kancane wehla.Ngaphezu kwalokho, inobunzima obuphezulu bobuso ngemuva komthelela ophindaphindiwe;inomthelela omuhle kakhulu wokumuncwa kwamandla, enenani eliphakeme kakhulu lokumunca amandla phakathi kwawo wonke amamodeli epulasitiki, ngakho inokunciphisa umsindo okuhle kanye nokunciphisa umsindo okuhle kakhulu;
(3) I-UHMWPE ezigcoba ngokwayo inesici sokungqubuzana esiphansi kakhulu (0.05～0.11), ngakho-ke yinhle kakhulu ekuzigcobeni.Kusukela kuThebula 1, kungabonakala ukuthi isici sokungqubuzana singaphansi kwe-polytetrafluoroethylene (PTEE) engcono kakhulu yokuzigcoba (PTEE), ngakho-ke ihlonishwa emkhakheni wesayensi yokungqubuzana njengento ephethe imisebenzi eyinhloko yemali;
(4) Ukumelana namakhemikhali.Inokumelana okuhle kwamakhemikhali.Ngaphezu kwama-asidi e-oxidizing aqinile, ingakwazi ukumelana nemithombo yezindaba ebolayo ehlukahlukene (njengama-acids, ama-alkali, nosawoti) kanye nemidiya ye-organic ezingeni lokushisa nokujula okuthile.I-solvent yetiye ingaphandle).Icwiliswa ezinhlotsheni ezingu-80 zezincibilikisi eziphilayo ku-20°C no-80°C izinsuku ezingu-30 ngaphandle kokubukeka okungavamile, kanye neminye imisebenzi yomzimba cishe ayishintshile;
(5) I-UHMWPE enganamatheli inamandla okukhangisa abuthaka kakhulu, futhi ikhono layo lokuvimba ukunamathela ingeyesibili ngemuva kwe-PTEE, okuyipulasitiki enganamatheli kakhulu, ngakho ukubukeka komkhiqizo akulula ukunamathela kwezinye. izinto zokwakha.Ngaphezu kwalokho, i-UHMWPE nayo inezici zokumelana nezinga lokushisa eliphansi (ukwenza i-roller isebenze esikalini esikhulu), inhlanzeko, engeyona enobuthi, kanye ne-hydrophobic (i-roller akulula ukumunca amanzi kanye nokukhubazeka).
Ukushiyeka kwe-UHMWPE: Uma kuqhathaniswa nezinsimbi namanye amapulasitiki obunjiniyela, ukumelana nokushisa, nobulukhuni buphansi, kodwa kungathuthukiswa ngokuthi "ukugcwalisa" kanye "nokuxhumanisa".
2. Ukuphakama kwe-ultra-high molecular weight polyethylenei-conveyor idler roller
(1) Ngenxa yokuthi i-coefficient yokumelana nokusebenza kanye ne-inertia egoqayo iyancipha kakhulu, ukusebenza kwe-roller kuba bucayi kakhulu futhi kuzinzile.I-polyethylene yesisindo samangqamuzana e-Ultra-high inomthelela omuhle ekumunceni nasekudambiseni amandla, okunganciphisa ngempumelelo umsindo osebenzayo futhi yenze imishini yokuthutha iqedele ibanga elide, umthamo omkhulu, kanye nokusebenza ngesivinini esikhulu.Kodwa-ke, uma kucatshangelwa ukushiyeka kwamandla aphansi we-polyethylene izinto zokusetshenziswa, kuyadingeka ukuba kudlule izibalo eziqinile kanye nokuhlolwa.
(2) Ngenxa yokuthi i-ultra-high molecular weight polyethylene roller inokubukeka kokunganamathiseli, ukungagqwali, nokuzigcoba, inokuvikela okungcono kwezokuthutha, ngisho nalapho i-roller yonakalisiwe futhi ingagingqiki, ngeke kulimale.Ibhande lokuthuthaakulula ukugqoka kanye nempilo yesevisi yebhande lokuhambisa,i-conveyor roller
I-UHMWPE Plastic Conveyor Belt Roller igcina zonke izici ezinhle kakhulu ze-polyethylene yesisindo samangqamuzana aphezulu kakhulu, ene-anti-friction self-lubrication, ukumelana komthelela, ukuqeda umsindo nokudlidliza, anti-adhesion, anti-corrosion, anti-ukuguga, njalonjalo. .Ngemva kokufakwa emakethe, i-UHMWPE Plastic Conveyor Belt Roller iye yamelana novivinyo lokusetshenziswa isikhathi eside futhi iye yamukelwa kahle amakhasimende.Isetshenziswa kabanzi ezimayini zensimbi, izimayini zamalahle, imboni yamakhemikhali, indawo yokugcina okusanhlamvu, izinto zokwakha, amachweba, amasimu kasawoti, amandla kagesi nezinye izimboni.Enye indlela engcono kakhulu.
Njengoba ama-roller amaningi evezwa uthuli nokungcoliswa kwamanzi, futhi impahla igqokwa noma igqwalile ngumzimba we-roller, i-roller efanelekile kufanele ibe nobuchwepheshe obuthathu obuyisisekelo:
1. I-labyrinth seal engangcolisi.Ubuchwepheshe;
2. ukunemba kokukhiqiza ama-roller, ukungaguquguquki kobuchwepheshe;
3. I-roller body anti-corrosion kanye nobuchwepheshe obungagugi.
Isici
Ingakwazi ukulawula umjikelezo wokuphila, ukugcinwa okuhleliwe okuhleliwe;
Ukuxazulula ukungqubuzana kokuthi ukusebenza kwamarola okujwayelekile kuhle futhi ukumelana nokuzungezisa kukhulu ngokuhambisanayo;
Nweba impilo yetheyiphu, indawo yerabha yerola, isinciphisi, kanye nemoto izikhathi ezingaphezu kwezi-5;
Ukukhipha inani elikhulu labasebenzi kanye nezinsiza ezibonakalayo ukuze zilungiswe;
Ukunciphisa kakhulu ukuqina kwabasebenzi futhi kuthuthukise impilo yabo;
Izindawo ezihlukene zingakhetha izinto ezihlukile zerola, ukutshalwa kwezimali okunengqondo kakhulu, nezindleko zokusebenza;
Nciphisa isikhathi sokuphumula, uthuthukise izinzuzo zezomnotho eziphelele zokuthutha izikhathi ezingu-5-8.
Uhlelo lokuvala olusebenzayo
I-labyrinth seal eyinhloko ivimbela uthuli oluningi ukuba lungene endlini ethwele, futhi akukho manzi angavuza.
imvume phakathi kwendlu ethwele kanye ne-shaft yakha uphawu lwesibili, indlu ephetheyo yenziwe nge-UHMWPE ene-
amandla aphansi kakhulu angaphezulu futhi awanamathele, ngakho ayanyanyeka othulini namanzi.Kunzima impela ukuthi uthuli ludlule
