Izinto zokuthwala ezisetshenziswa kumaphampu e-centrifugal zihlukaniswe ikakhulukazi izigaba ezimbili: izinto zensimbi nezingezona ezensimbi.

Metallic Material

Izinto zensimbi ezivame ukusetshenziselwa izinto zensimbi kumabheringi ashelelayo zihlanganisa ama-alloys anama-alloys (owaziwa nangokuthi ama-alloys e-Babbitt noma ama-alloys amhlophe), insimbi esakazwayo engagugi, ama-alloys asekelwe ethusi kanye ne-aluminium.

1. I-Bearing Alloy

Izingxenye eziyinhloko ze-alloy ezithwala ama-alloys (ezaziwa nangokuthi ama-alloys e-Babbitt noma ama-alloys amhlophe) yithini, i-lead, i-antimony, ithusi, i-antimony, ne-copper, esetshenziselwa ukuthuthukisa amandla nobulukhuni be-alloy. Iningi lezakhi ze-alloy ezithwalayo zinamaphuzu aphansi ancibilikayo, ngakho-ke afaneleka izimo zokusebenza ezingaphansi kuka-150 °C.

2. Ingxubevange eyenziwe ngethusi

Ama-alloys asekelwe ethusi ane-conductivity ephezulu ye-thermal kanye nokumelana nokugqoka okungcono kunensimbi. Futhi i-alloy-based alloy ine-machinability enhle kanye ne-lubricity, futhi udonga lwayo lwangaphakathi lungaqedwa, futhi luthintana nobuso obushelelezi be-shaft. 

Izinto ezingezona ezensimbi

1. I-PTFE

Inezici ezinhle zokuzithambisa kanye nokuzinza okuphezulu kwe-thermal. I-friction coefficient yayo incane, ayimumbi amanzi, ayinamatheli, ayivuthi, futhi ingasetshenziswa ngaphansi kwesimo sika -180~250°C. Kodwa kukhona futhi okungalungile okufana ne-coefficient enkulu yomugqa wokunweba, ukuzinza kwe-dimensional embi, kanye nokungahambi kahle kwe-thermal. Ukuze kuthuthukiswe ukusebenza kwayo, ingagcwaliswa futhi iqiniswe ngezinhlayiya zensimbi, imicu, igraphite nezinto ezingaphili.

2. I-graphite

Kuyinto enhle yokuzithambisa, futhi ngenxa yokuthi kulula ukuyicubungula, futhi uma iphansi, isuke ibushelelezi, ngakho-ke iyimpahla yokuzikhethela yama-bearings. Kodwa-ke, izici zayo zemishini zimbi, futhi ukumelana kwayo komthelela namandla okuthwala umthwalo kubi, ngakho ifaneleka kuphela izikhathi zokulayisha ukukhanya. Ukuze kuthuthukiswe izakhiwo zayo zemishini, ezinye izinsimbi ezifusible ezinokumelana nokugqokwa okuhle zivame ukufakwa. Izinto ezisetshenziswa kakhulu zokufakelwa yi-Babbitt alloy, i-copper alloy ne-antimony alloy. 

3. Irabha

I-polymer eyenziwe nge-elastomer, enokunwebeka okuhle nokumunca ukushaqeka. Kodwa-ke, ukuqhutshwa kwayo okushisayo kumbi, ukucubungula kunzima, izinga lokushisa elivumelekile lokusebenza lingaphansi kuka-65 ° C, futhi lidinga amanzi ajikelezayo ukuze agcobe futhi apholile ngokuqhubekayo, ngakho akuvamile ukusetshenziswa.

4. Carbide

Inochungechunge lwezakhiwo ezinhle kakhulu njengokuqina okuphezulu, ukumelana nokugqoka, amandla amahle nokuqina, ukumelana nokushisa, nokumelana nokugqwala. Ngakho-ke, ama-sliding bearings acutshungulwa ngayo anembayo ephezulu, ukusebenza okuzinzile, ubulukhuni obuphezulu, amandla amahle, nokuqina, kodwa ayabiza.

5. SiC

Iwuhlobo olusha lwezinto ezingezona ezensimbi ezihlanganiswe ngokwenziwa. Ubulukhuni bungaphansi kobedayimane. Inokumelana nokugqwala kwamakhemikhali okuhle, ukumelana nokugqokwa, ukumelana nokushisa okuphezulu, amandla aphezulu emishini, ukusebenza kahle kokuzigcoba, ukumelana nokukhuphuka kwezinga lokushisa eliphezulu, into encane yokungqubuzana, ukuguquguquka kokushisa okuphezulu, kanye ne-coefficient ephansi yokwanda okushisayo. Ingasetshenziswa kabanzi Isetshenziswa ku-petroleum, i-metallurgy, imboni yamakhemikhali, imishini, i-aerospace namandla enuzi kanye neminye imikhakha, ivame ukusetshenziswa njengempahla ehambisanayo yokushayisana kwama-sliding bearings kanye nezimpawu zemishini.
