Cov khoom siv bearing tuaj yeem nyob rau hauv kev teeb tsa los ntawm bolting, tack-welding, tag nrho cov vuam lossis mortar embedment, thiab hom kev tsim nyog ntawm cov kabmob yuav tsum raug xaiv raws li txoj kev teeb tsa.Lub PTFE yuav tsum muaj kev tiv thaiv zoo tiv thaiv weld spatter, pleev xim rau, hlau swarf thiab lwm yam, thaum lub sij hawm installation.
Nyob rau hauv ntau yam kev siv, PTFE swb bearings yog superior rau cov pa expansion daim hlau, rollers thiab rocker caj npab hom kev txhawb nqa.Lawv txhawb cov nroj tsuag petrochemical, cov tshuab hnyav, cov kav dej, cov tsev thiab cov girders;Lawv ua raws li kev nthuav dav, kev cog lus thiab lwm yam kev sib txuas lus ntawm cov qauv uas txav los ntawm thermal, seismic lossis txawv zog.
Cov kabmob rau cov ntawv thov no yuav tsum ua haujlwm ntawm kev thauj khoom siab thiab qis qis, thiab nws tsuas yog nyob rau hauv cov xwm txheej no uas tus kheej lub zog ntawm PTFE yog qhov siab tshaj plaws.Qhov tseem ceeb no, ua ke nrog nws tsis muaj nplaum nplaum thiab tiv thaiv huab cua, yog lub hauv paus ntsiab lus vim li cas PTFE tau ua pov thawj kom ua tiav zoo li cov khoom siv swb.
Qhov zoo
1 Qhov yooj yim ntawm cov kabmob tsim thiab nws yooj yim ntawm fabrication thiab installation ua rau chav tsev nqi npaum li cas.2 Cov nqi ntawm kev tsim kho tuaj yeem raug txo los ntawm kev tsim kom nthuav dav es tsis yog strain.3 Coefficient ntawm kev sib txhuam ntawm cov kabmob nto tseem nyob tas li, txawm tias nyob rau hauv Cov xwm txheej phem tshaj plaws.4 Cov kabmob muaj kev saib xyuas tsis pub dawb - PTFE yog qhov ua rau nws tus kheej lubricating, thaum cov khoom siv hauv av yog absorbed rau hauv cov khoom.Tsuas yog kev tiv thaiv yooj yim yog yuav tsum tau tiv thaiv qhov tseem ceeb ingress ntawm av.
Coefficient ntawm kev sib txhuam
Lub coefficient ntawm kev sib txhuam ntawm PTFE cov ntaub ntawv yog nyob ntawm ntau yam sib txawv, nrog rau kev siab, zawv zawg tshaj tawm thiab kub.Kev xav tau muab faib rau cov txiaj ntsig ntawm qee qhov kev hloov pauv, txawm hais tias nws tau pom zoo tias kev kub siab thiab qis tshaj tawm nyiam kev sib txhuam qis.
Cov coefficient tsawg dua li ntawm lwm yam khoom siv engineering.Nws tau raug tshaj tawm ntau yam los ntawm 0.02 txog 0.2, tab sis qhov no nyob ntawm qhov kev npaj nto thiab txoj kev sim.Daim ntawv qhia kev thauj khoom / kev sib txhuam qhia tau hais tias qhov cuam tshuam ntawm kev thauj khoom.
Feem ntau, cov coefficient ntawm kev sib txhuam ntawm qhov chaw mating thiab PTFE swb bearing ncoo yuav yog qhov tsawg kawg nkaus thaum qhov kev ntxhov siab hauv PTFE yog qhov siab tshaj plaws (raws li kev txwv tsis pub nkag), cov kabmob yog tsim los ntawm PTFE unfilled, thiab qhov kawg ntawm mating nto yog polished heev.
Tsis tas li ntawd, ib qho tseem ceeb ntawm kev sib txhuam ntawm PTFE yog qhov tsis muaj 'stick-slip', vim tias tsis zoo li tag nrho lwm cov kabmob sib xyaw ua ke, qhov sib txhuam zoo li qub ntawm PTFE yog sib npaug los yog tsuas yog marginally siab tshaj qhov kev sib txhuam dynamic.
