Hav nyob ntawd! Raws li ib tug neeg muag khoom ntawm graphite hlab, kuv feem ntau tau nug txog cov lubrication yuav tsum tau rau graphite hlab nyob rau hauv daim ntawv thov bearing. Yog li, kuv xav tias kuv yuav sau qhov blog no los qhia qee qhov kev nkag siab ntawm lub ncauj lus no.
Ua ntej tshaj, cia peb nkag siab tias yog vim li cas lubrication tseem ceeb rau graphite hlab hauv bearings. Bearings yog cov khoom tseem ceeb hauv ntau lub tshuab, thiab lawv cia siab rau kev txav mus los kom ua haujlwm zoo. Graphite raj, siv rau hauv cov kabmob, yuav tsum tau txo kev sib txhuam thiab hnav kom ntseeg tau ntev - kev ua tau zoo thiab kev ua haujlwm zoo. Lubrication pab ua kom tiav cov hom phiaj no los ntawm kev tsim cov yeeb yaj kiab nyias ntawm cov raj graphite thiab cov chaw sib cuag.
Hom Lubricants rau Graphite Tubes hauv Bearings
Muaj ntau hom roj nplua nyeem uas tuaj yeem siv nrog cov raj graphite hauv kev siv cov kabmob.
Roj Lubricants
Roj yog qhov kev xaiv nrov rau ntau daim ntawv thov kabmob. Nws yog ib nrab - roj nplua nyeem uas tuaj yeem nyob hauv qhov chaw yooj yim, muab sijhawm ntev - lubrication. Roj muaj ib lub hauv paus roj thiab ib tug thickening neeg sawv cev. Cov roj hauv paus muab cov khoom siv lubricating tiag tiag, thaum tus neeg sawv cev thickening pab kom cov roj nyob hauv qhov chaw.
Thaum nws los txog rau graphite hlab, siab - roj zoo nrog anti - hnav additives feem ntau pom zoo. Cov additives no tuaj yeem txo qhov hnav ntawm graphite tube nto. Piv txwv li, qee cov roj muaj molybdenum disulfide, uas yog cov roj nplua nyeem uas tuaj yeem txhim kho cov nyhuv lubricating, tshwj xeeb tshaj yog nyob rau hauv siab - load tej yam kev mob.
Roj Lubricants
Cov roj lubricants kuj tseem siv tau. Lawv muab cov cua kub zoo dua piv rau cov roj, uas yog qhov tseem ceeb hauv siab - cov ntawv thov ceev. Muaj cov viscosities sib txawv ntawm cov roj muaj, thiab qhov kev xaiv nyob ntawm qhov kev ua haujlwm ntawm cov kabmob.
Rau cov raj graphite, cov roj hluavtaws feem ntau nyiam. Cov roj hluavtaws muaj cov tshuaj lom neeg ruaj khov zoo dua thiab tuaj yeem tiv taus ntau qhov kub thiab txias. Lawv kuj muaj qis volatility, uas txhais tau hais tias lawv yuav tsis evaporate yooj yim, kom ntseeg tau tias lubrication tas li.
Cov yam ntxwv cuam tshuam rau cov kev xav tau lubrication
Ua haujlwm kub
Kev khiav hauj lwm kub plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov kev xav tau lubrication. Thaum qhov kub thiab txias, lub viscosity ntawm lub lubricant tuaj yeem txo qis, uas tuaj yeem ua rau lubrication tsis txaus. Nyob rau hauv tas li ntawd, lub lubricant nrog ib tug high viscosity index yog xav tau. Hom lubricant no tuaj yeem tswj tau nws cov viscosity dhau qhov kub thiab txias.
Ntawm qhov tod tes, ntawm qhov kub tsis tshua muaj, cov roj nplua nyeem tuaj yeem ua tuab dhau, ua rau nws nyuaj rau cov kabmob txav mus los. Yog li, lub roj nplua nyeem uas muaj qhov tsis zoo - kub fluidity yog qhov tseem ceeb.
Thauj khoom
Lub load ntawm cov kabmob yog lwm qhov tseem ceeb. Cov loads siab dua yuav tsum muaj cov roj nplua nyeem nrog kev thauj khoom zoo dua - nqa lub peev xwm. Rau hnyav - load daim ntawv thov, roj nrog huab - siab (EP) additives feem ntau yog siv. Cov additives no tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm lub graphite tube nto, tiv thaiv cov hlau ncaj qha - rau - hlau tiv tauj hauv siab loads.
Ceev
Qhov ceev ntawm cov kabmob cuam tshuam rau lub lubrication ib yam nkaus. Nyob rau hauv siab - daim ntawv thov ceev, cov roj nplua nyeem yuav tsum muaj peev xwm tsim tau ib zaj duab xis ruaj khov sai. Cov roj lubricants feem ntau zoo dua rau siab - ceev bearings vim tias lawv tuaj yeem ntws tau yooj yim dua thiab muab lubrication sai dua.
Cov txiaj ntsig ntawm Lubrication Zoo
Txo kev sib txhuam
Kev lubrication zoo txo qhov kev sib txhuam ntawm cov graphite raj thiab cov kabmob nto. Qhov no tsis tsuas yog txhim kho kev ua haujlwm ntawm lub tshuab, tab sis kuj txo qis kev siv zog. Thaum muaj kev sib txhuam tsawg dua, lub tshuab tsis tas yuav ua haujlwm nyuaj rau kev khiav lag luam, uas tuaj yeem ua rau cov nqi txuag tau ntev.
Extended Service Life
Los ntawm kev txo qhov hnav thiab tsim kua muag ntawm lub raj graphite, lubrication kom zoo tuaj yeem ua rau nws lub neej kev pab. Lub qhov dej - lubricated graphite raj tsis tshua muaj peev xwm tsim cov kab nrib pleb lossis lwm yam kev puas tsuaj, uas txhais tau hais tias nws tuaj yeem ua haujlwm tau zoo rau lub sijhawm ntev dua. Qhov no txo qhov zaus ntawm kev hloov raj, txuag lub sijhawm thiab nyiaj txiag.
Txhim kho kev ua tau zoo
Lubrication kuj pab txhim kho kev ua tau zoo tag nrho ntawm cov kabmob. Nws ua kom muaj kev ua haujlwm du thiab ntsiag to, uas yog qhov tseem ceeb hauv ntau daim ntawv thov, tshwj xeeb tshaj yog cov suab nrov thiab kev vibration yuav tsum tau txo qis.
