Ukukhethwa komthumeliroller

I-Conveyor rollerisetshenziselwa ukusekela ibhande lokuthutha kanye nezinto ezisebhande, ukunciphisa ukumelana nokusebenza kwebhande lokuthutha, ukuqinisekisa ukuthi i-sag yebhande lokudlulisa akudluli imithetho yezobuchwepheshe, futhi lenze ibhande lokuthutha lisebenze ngokushelela endleleni enqunywe kusengaphambili.

I-roller ngokuya ngokusetshenziswa kwayo ihlukaniswe ikakhulukazi i-carrier roller, i-return roller, i-impact roller kanye ne-roller yokuqondisa.I-roller ingenye yezingxenye ezibalulekile ezithinta ukusebenza komthumeli, ibalwa cishe ngama-30% ~ 40% wekhwalithi ye-conveyor yonke, 25% ~ 30% yenani lentengo yawo wonke umthumeli, futhi iyingxenye eyinhloko yansuku zonke. ukuphathwa, ukuvikelwa kanye nokushintshwa.Ukuhlelwa nokukhethwa kwe-roller kunethonya elibalulekile ekusebenzeni okujwayelekile komshini wokuthutha, umsebenzi ozinzile, ukusetshenziswa kwamandla kanye nenani le-conveyor yonke.Ikakhulukazi esimweni sejubane eliphezulu lebhande, izidingo ze-roller ziba nzima kakhulu.

Njengengxenye eyinhloko ye-conveyor, i-roller iye yaqina kakhulu ngokuthuthuka kwejubane lebhande.Izinto eziyinhloko ezithinta ukusebenza kwejubane eliphezulu kwerola inani eliphelayo kanye nenani lokumelana nokuzungezisa.Lapho i-roller isebenza ngesivinini esikhulu, isakhiwo sokuvala i-roller sizothinteka ngokushisa nezinye izizathu.Ukuhlelwa kwesakhiwo se-roller enesivinini esikhulu kuhlongozwa kuleli phepha.

1.Sealing isakhiworoller

Isakhiwo sokubeka uphawu siyisici esibalulekile esithinta impilo yokusebenza kanye nokumelana nokusebenza kwe-roller.Kunezindlela ezimbili eziyinhloko zesakhiwo sokuvala ama-roller emakethe:

(1) Uphawu olungathinteki (njenge-labyrinth seal).Ukumelana nokusebenza kwalolu hlobo lokubeka uphawu kuncane, kodwa ngenxa yokuba khona kokungqubuzana kwangaphakathi lapho usebenza ngesivinini esikhulu, nakanjani kuzoholela ekuveleni kokushisa.Ngokushintsha komfutho womoya, izinhlayiya zothuli zingena emgodini we-bearing seal kanye nenqubo yokuhogela, okubangela ukuthi i-bearing isebenze esimweni sokungqubuzana kokuphazamiseka, futhi kubhebhethekise ukuguga kwe-bearing.

(2) Thinta uphawu lohlobo.Umphumela wokuvala ungcono kunohlobo olungathinteki, kodwa ukumelana nokusebenza kukhulu.Endabeni yokushisa okukhulu nokwehluka kwengcindezi nokusabalalisa okungalingani, ukuguqulwa kwe-elastic yomlomo wokuvala nawo akuhambisani, okubangela umphumela omubi wokuvala.

Akulungile ukwengeza umphumela wokuvala kuphela ngokungeza inani lamaphaseji okuvalwa nobude bokuvala.Isakhiwo se-labyrinth sealing yegebe lokuqala elijikelezayo liyisihluthulelo sokubhekana nenkinga yokuvala, izinkinga zegebe, i-slime noma amanzi azogeleza esiteshini sangaphakathi se-labyrinth, okubangela ukwehluleka kwe-roller, inombolo enjalo ye-maze ayinangqondo.

I-roller ehlongozwayo kuleli phepha yamukela isakhiwo esiyinhlanganisela se-axial labyrinth seal kanye ne-touch seal, futhi izici zayo zimi kanje:

(1) Inombolo yamaphaseji okuvalwa kwe-axial labyrinth seal ayithinteki esikalini se-radial ye-bearing, futhi ingangezwa ngokufanelekile.Indawo evalekayo ye-axial labyrinth isendaweni efanayo namandla amaphakathi okugeleza kwamanzi.Amanzi angenile

uphawu lapho i-roller ijikeleza izogeleza iye phezulu kwe-labyrinth eduze kwendawo yokuvala ngaphansi komphumela wamandla we-centrifugal.Ukuze kuthuthukiswe umphumela, phezulu kwendandatho yangaphakathi yokuvala ingabhekwa njengokukhetha isakhiwo se-arc esiyindilinga.

(2) Faka indandatho yokuvala ohlangothini olungaphandle lwe-labyrinth seal ukuze wenze uphawu lokuthinta, olungakwazi ukubhekana kuphela "nenkinga yokuphefumula" ye-labyrinth seal, kodwa futhi ngeke ingeze ukujula kwesihlalo esithwalayo njenge ezinye izakhiwo ezihlanganisiwe zophawu.Indandatho yokuvala i-NBR/PA6, isisindo esilula, ukumelana nokugqwala, i-coefficient yokungqubuzana incane kunamanye amapulasitiki obunjiniyela.

(3) engeza indandatho ye-convex eringini ye-baffle yangaphakathi (bheka uMdwebo 1), shintsha isiqondiso sokunyakaza kwe-axial lapho uthuli noma amanzi kungena isikhala seringi ye-baffle yangaphakathi.Lapho i-roller isebenza ngesivinini esikhulu, kuzokwenziwa isivacu phakathi kweringi ye-convex nendandatho ye-baffle yangaphandle ukuze kuqinisekiswe umphumela wokuvala.

2.Izici zenqubo nokukhethwa kwezinto ezibonakalayo

Ukuphuma kwe-radial kwe-roller ngokuyinhloko kuncike ephutheni le-radial yesilinda, ikhwalithi yesihlalo esithwalayo kanye ne-coaxiality yenqubo yokuhlanganisa.Inani le-radial run-out le-roller linethonya elikhulu emsebenzini obushelelezi we-conveyor, ikakhulukazi uma inani le-radial run-out likhulu kakhulu ngesivinini esikhulu, ibhande lokudlulisa lizozulazula ngobudlova futhi lithinte umsebenzi ovamile.

Njengamanje, iningi lama-roller ama-rollers ashintshwa ngamapayipi ensimbi, anzima ngekhwalithi.Izinga lamapayipi, i-ovality kanye nokubekezelelana kobubanzi bangaphandle akulula ukuqinisekiswa, ikakhulukazi ukuba khona kokuyeka ukwakhiwa kwe-barrel kuthinta i-coaxiality, futhi kulula ukubangela ukuba ama-roller abe yi-eccentric.Ukudlidliza ngezikhathi ezithile kuzokwenzeka ngenxa yamandla e-centrifugal phakathi nenqubo yokusebenza, okuzothinta ukusebenza kahle kwebhande lokuthutha.

3. Ukukhetha okuthwala i-roller

Ukuphila kokusebenza kwe-roller ngokuyinhloko kuncike ekuthwaleni nasekufakweni uphawu.Abavilapha abaningi emakethe basebenzisa ama-bearings amakhulu.Uma kuqhathaniswa nama-bearings avamile, ama-bearings amakhulu ane-clearance enkulu nama-diameters ebhola, anganciphisa ukuzwela ku-coaxiality futhi athuthukise ikhono lokuzivumelanisa nezinto zangaphandle.

Kodwa-ke, ukukhethwa kwama-bearings ane-clearance enkulu kuzothinta kakhulu umthamo wokuthwala i-axial we-idler, ikakhulukazi ngemva kokunyuka kwejubane lebhande, ukunyakaza kwe-axial bearing umthamo kuzobangela isimo esingasebenzi esingalingani somthumeli webhande.Ngisho nasezikhathini ezinzima, kuyadingeka ukumisa umshini wokulungisa iphutha nokulungisa kabusha kusukela ekuqaleni.

Kuleli phepha, sihlela ukukhetha ama-deep groove ball bearings anesembozo sothuli, esingakwazi kuphela ukuqinisekisa ukuhlanzeka kwangaphakathi kwe-bearing, ukuthuthukisa umthamo we-axial bearing, ukunciphisa ukulimala okuvamile ekuthwaleni okubangelwa i-axial high-frequency. amandla omthelela, kodwa futhi uqinisekise ukusebenza okushelelayo kokuthwala kunweba impilo yangempela yokusebenza yebheringi.

Leli phepha lenze ucwaningo oluyisisekelo kuma-roller anesivinini esiphezulu kusukela ezicini zesakhiwo, ukuvala, ukusetshenziswa kanye nobuchwepheshe bezinto ezintsha.I-roller ithatha isakhiwo sokuvala esiyinhlanganisela esihlanganisa i-axial labyrinth kanye ne-touch labyrinth, futhi isebenzisa i-deep groove ibhola elinesembozo sothuli.Ukusetshenziswa kwezinto ezintsha kanye nokushintshwa kobuchwepheshe bokucubungula kuqinisekisa ukumelana nokujikeleza kwe-roller, ukugxuma kwe-radial circular kanye nokungangeni kwamanzi, ukuvala uphawu okungenathuli kanye neminye imisebenzi.Ngaphansi kokuqondisa kokuthuthukiswa kwamandla aphezulu, amabanga amade kanye nama-conveyors amakhulu, isakhiwo se-Roller esihlongozwayo kuleli phepha sinokuphikiswa okuncane okujikelezayo, umsindo ophansi nokuphila isikhathi eside sokusebenza, okudlala indima ebalulekile emandleni okukhipha isithuthi sejubane.
