Kungani ukusebenza kwe-plastic bearing kungcono kunokwensimbi yensimbi

 

1. Ithemba lokuthuthukiswa kwamabheringi epulasitiki

Okwamanje, amakhasimende amaningi kukhona namanje uzimisele ukukhetha insimbi yensimbi imishini.Phela, lapho ama-plastic bearings engakhiqizwa, ama-metal bearings ayesetshenziswa njengezinto zendabuko. Kodwa kuze kube manje, ukusebenza kwama-bearings epulasitiki kuzoba ngcono futhi kube ngcono esikhathini esizayo.

2.Izinto zokuthwala ipulasitiki kanye izinzuzo

TIzindleko zokukhiqiza zepulasitiki ziphansi kunezinsimbi zensimbi, futhi izinhlobonhlobo zezinto zepulasitiki ziya ngokucebile futhiesetshenziswa ezimbonini eziningi, izinto zepulasitiki ezivamilekukhona inayiloni, i-polytetrafluoroethylene, i-polyethylene ne-PEEK.

I amabombo epulasitiki is ukuguquguquka, umnotho kanye nenhlanzeko .Ziningi izinto ezingabizi kakhulu ezitholakalayo zezinhlelo zokusebenza ezahlukahlukene.Amabheringi epulasitiki ngokuvamile enziwa ngama-alloys e-thermoplastic ane-fiber matrix kanye ne-lubricant eqinile, enamandla amakhulu kanye ne-coefficient ephansi yokungqubuzana.

3. Kuyini ukusebenza okuhle kwama-bearings epulasitiki ?

(1) Ukuzithambisa

Ipulasitiki's izici ezingokwemvelo, igcoba ama-bheringi, inciphisa ukubambezeleka kokuqala futhi igcine indawo ihlanzekile.I-bearing encane igqoke ekuqaleni futhi idlala indima yokugcoba i-bearing, kodwa ukuguqulwa kwe-bearing ngokwayo kunganakwa.Lokhu futhi kwenza ama-bearings epulasitiki afaneleke kakhudlwana ekufakweni kokudla, ngoba i-FDA ibeka imingcele ngokuqinile ukusetshenziswa kwamafutha emishinini yokukhiqiza ukudla.Ngaphezu kwalokho, nakuba uthuli nezinye izinhlayiya zizonamathela ku-lubricant futhi zenze ungqimba lokungcola, ngenxa yokuthwala kwepulasitiki, noma yiziphi izinhlayiya zizovele zifakwe ekuthwaleni futhi ngeke zithinte ukusebenza.

(2) Ukusebenza ekushiseni okuphansi nokuphezulu

Ama-bearings epulasitiki angasebenza ngokuqhubekayo kunoma yikuphi ukushisa okuphakathi kuka -4° C futhi 260° C futhi ingamelana namazinga okushisa afika ku-600° F. I-plastic bushing ingaba namandla njengensimbi, kodwa ukuzala udonga luncane, ngokuvamile luwu-0.0468 "- 0.0625" oluwugqinsi.Izindonga ezizacile zinikeza ukunqanyulwa kokushisa okungcono, okuholela ebangeni elikhulu lokusebenza nokuncipha kokuguga.Ngaphezu kwalokho, izindonga ezincanyana zilula futhi mancane amathuba okuba zikhubazeke, zizenze zifanelekele izinhlelo zokusebenza ezinezinkinga zesisindo.

(3) Ukusebenza kwemvelo

Ngenxa yesisindo esincane sepulasitiki, ama-plastic bearings ayonga kakhulu uphethiloli.Amabhodi epulasitiki awadingi ukumbozwa okwengeziwe noma izithasiselo ukuze kukhiqizwe imiphumela efanayo nezingxenye zensimbi ezivame ukungezwa ngezinto eziyingozi.Ngaphezu kwalokho, ukukhiqizwa kwepulasitiki kudinga kuphela amafutha angu-10-15% uma kuqhathaniswa nenani elifanayo le-aluminium noma insimbi.

(4) Ukumelana okuhle kwamakhemikhali

Amabhodi epulasitiki ngokuvamile amelana kakhulu namakhemikhali nezinto ezihlukahlukene kunamabhodi ensimbi, futhi amelana nokuklwebheka nokuguga kwamabheringi ensimbi.Lokhu kusiza ukugcina i-coefficient yabo ephansi yokungqubuzana futhi ihambe kahle ngaphandle kokuphazamiseka okuncane.

(5) Ukugcinwa kwamahhala

Khetha ipulasitiki efanele ngokuya ngendawo oyisebenzisayo, futhi ukuthwala kungamelana nokugqwala ngokuhamba kwesikhathi.Ngemuva kokufakwa, ukuthwala kwepulasitiki kunomsebenzi omude futhi akudingi ukushintshwa.Ukugqwala kungabangela ama-metal bearings ukuba abe yiqhwa endaweni, okwenza kucishe kube nzima ukuwasusa ngaphandle kokuwasika.Ama-bearings epulasitiki kulula ukuwasusa.

(6) Intengo ephansi yamapulasitiki

Amapulasitiki amaningi ashibhile kunezinsimbi.Ngakho-ke ama-bearings epulasitiki kanye nama-plastic bushings anganciphisa izindleko
