Izinto zokuthwala ezisetyenziswe kwiimpompo ze-centrifugal zihlulwe kakhulu zibe ngamacandelo amabini: izinto zetsimbi kunye nezinto ezingezona zetsimbi.

Metallic Material

Izixhobo zetsimbi ezisetyenziswa ngokuqhelekileyo izixhobo zetsimbi kwiibheringi ezityibilikayo zibandakanya ii-alloys ezithwalayo (ezaziwa ngokuba zii-alloys ze-Babbitt okanye ii-alloys ezimhlophe), intsimbi engagungqiyo, i-copper-based and aluminium-based alloys.

1. Ukuthwala iAlloy

Amacandelo aphambili e-alloy yokuthwala i-alloys (ekwabizwa ngokuba yi-Babbitt alloys okanye i-alloys emhlophe) yi-tin, i-lead, i-antimony, i-copper, i-antimony, kunye nobhedu, ezisetyenziselwa ukuphucula amandla kunye nobunzima be-alloy. Uninzi lwezinto ezithwala i-alloy zineendawo eziphantsi zokunyibilika, ngoko ke zifanelekile kwiimeko zokusebenza ezingaphantsi kwe-150 °C.

2. I-Alloy esekwe kwiCopper

I-alloys esekelwe kwi-Copper ine-conductivity ephezulu ye-thermal kunye nokumelana nokugqoka okungcono kunentsimbi. Kwaye i-alloy-based alloy ine-machinability elungileyo kunye ne-lubricity, kwaye udonga lwayo lwangaphakathi lunokugqitywa, kwaye ludibanisa nobuso obushelelezi be-shaft. 

Izinto ezingezizo ezentsimbi

1. PTFE

Ineempawu ezilungileyo zokuzithambisa kunye nokuzinza okuphezulu kwe-thermal. I-friction coefficient yayo incinci, ayifunxi amanzi, ayincangathi, ayivuthi, kwaye inokusetyenziswa phantsi kwe-180 ~ 250 ° C. Kodwa kukwakho nezinto ezingeloncedo ezinje nge-coefficient yokwandiswa komgca omkhulu, uzinzo olulambathayo, kunye nokungahambi kakuhle kwe-thermal. Ukuze kuphuculwe ukusebenza kwayo, inokuzaliswa kwaye iqiniswe ngeentsimbi zetsimbi, iifibers, igraphite kunye ne-inorganic substances.

2. Igraphite

Yinto efanelekileyo yokuzithambisa, kwaye ngenxa yokuba kulula ukuyiqhuba, kwaye ngakumbi iphantsi, ilula ngakumbi, ngoko yinto ekhethiweyo yokuzikhethela iibheringi. Nangona kunjalo, iipropathi zayo zoomatshini zimbi, kwaye ukuchasana kwayo neempembelelo kunye nomthamo wokuthwala umthwalo kubi, ngoko ke ifanelekile kuphela kwizihlandlo zomthwalo olula. Ukuze kuphuculwe iipropathi zayo zoomatshini, ezinye iintsimbi ezixubeneyo ezinokumelana nokunxiba kakuhle zihlala zikhulelwa. Izinto ezisetyenziswa ngokuqhelekileyo zokufakela i-Babbitt alloy, i-alloy yobhedu kunye ne-antimony alloy. 

3. Irabha

Yipolymer eyenziwe nge-elastomer, ene-elasticity elungileyo kunye nokufunxa ukothuka. Nangona kunjalo, ukuqhutyelwa kwayo kwe-thermal kubi, ukucutshungulwa kunzima, ukushisa okuvumelekileyo okusebenzayo kungaphantsi kwe-65 ° C, kwaye idinga amanzi ajikelezayo ukuze igcobe kwaye ipholile ngokuqhubekayo, ngoko ayifane isetyenziswe.

4. Carbide

Inoluhlu lweepropathi ezigqwesileyo ezinjengokuqina okuphezulu, ukuxhathisa ukunxiba, ukomelela okulungileyo kunye nokuqina, ukumelana nobushushu, kunye nokumelana nomhlwa. Ke ngoko, iibheringi ezityibilikayo ezicutshungulwayo zichaneke kakhulu, zisebenza ngokuzinzileyo, ukuqina okuphezulu, ukomelela okuhle, kunye nokuqina, kodwa zibiza kakhulu.

5. ISiC

Ludidi olutsha lwemathiriyeli eyenziweyo eyenziwe nge-inorganic non-metallic. Ubunzima bungaphantsi kobo bedayimani. Inokumelana nokugqwala kweekhemikhali, ukumelana nokunxiba, ukumelana nobushushu obuphezulu, ukomelela okuphezulu koomatshini, ukusebenza kakuhle kokuzithambisa, ukuxhathisa ubushushu obuphezulu, i-friction factor encinci, i-thermal conductivity ephezulu, kunye nokwanda kwe-thermal coefficient. Ingasetyenziswa ngokubanzi Ukusetyenziswa kwi-petroleum, isinyithi, ishishini lemichiza, oomatshini, i-aerospace kunye namandla enyukliya kunye neminye imimandla, ihlala isetyenziswa njengesixhobo sokukhuhlana kweebheringi ezityibilikayo kunye nezitywina zoomatshini.
