Cov kabmob hauv lub cav tau siv los txhawb nqa cov khoom siv txav chaw thiab tiv thaiv cov khoom no los ntawm kev sib txhuam tsis zoo. Lub cav hnyav dua thiab muaj zog dua, cov kabmob muaj zog yuav tsum yog txhawm rau muab qhov kev txhawb nqa no thiab kev tiv thaiv. Xyoo 1839, tau tsim cov khoom tshwj xeeb hu ua Babbitt hlau. Babbitt hlau tau saws sai los ua kom muaj zog hu ua Babbitt bearings. Babbitt bearings tau siv dav hauv cov khoom siv roj hnyav uas siv lub cav. Cov cuab yeej siv no tau hais daws qhov xav tau hnyav, xws li milling, npaj thiab txiav ntoo. Los ntawm xyoo 1949, kev txhim kho hlau los ntawm Kev Tsov Rog Thoob Ntiaj Teb Zaum Ob tau ua rau Babbitt coj los siv tsis tau siv rau hauv tsheb. Txawm li cas los xij, ntau tus uas qhuas lub sijhawm hwm txoj hauv kev txuas ntxiv siv cov cuab yeej siv roj av nrog Babbitt cov kabmob. Raws li Babbitt cov kabmob tsis muaj kev lag luam ntxiv lawm, cov neeg txhawb siab no yuav tsum nchuav thiab pov lawv tus kheej Babbitt cov kabmob. Siv cov lus qhia no kom paub yuav ua li cas txhawm rau Babbitt bearings.
Cov kauj ruam
Kauj Ruam 1. Tshem cov kabmob qub
Babbitt bearings tau khov thiab yuav tsum tau yaj tawm nrog lub teeb hluav taws xob oxy-acetylene, muaj nyob ntawm cov khoom kho vajtse thiab cov khw muag khoom tsim khoom. Qhib cov ntaub ntawv kabmob thiab yaj tawm cov kabmob qub, ua kom ntseeg tau tias koj yaj cov tuav cov qhov thiab qhov, ib yam. Sau cov Babbitt yaj nyob rau hauv cov hlau cam khwb cia hlau yaj yaj hauv lub lauj kaub, muaj nyob ntawm cov chaw xa khoom. Khawb seem Babbitt los ntawm cov ntaub ntawv kabmob, zawj thiab qhov thiab ntxiv rau hauv lub lauj kaub.
Kauj Ruam 2. Tau Babbitt ntau dua
Koj yuav tsum tsis txhob rov siv Babbitt uas tau yaj tawm vim yog qhov tsis huv los ntawm kev siv xyoo. Txiav txim siab qhov alloy ntawm Babbitt uas koj xav tau. Koj tuaj yeem txiav txim siab qhov twg xav tau cov hlau uas muaj qhov nrawm ntawm qhov taub thiab qhov ntim cov kabmob yuav tau saib xyuas. Tin thiab Lead raws Babbitts muaj cov sib txawv sib txawv rau cov khoom sib txawv thiab siv. Cov mis hauv cov lus qhia hauv qab no yuav pab koj nrhiav qhov Babbitt alloy haum rau koj cov kabmob. Babbitt hlau feem ntau muaj nyob ntawm cov chaw muab khoom txiav ntoo, cov tuam txhab chipper lossis qee lub khw muag khoom kho vajtse. Nws kuj tseem muaj kom xaj ncaj qha los ntawm cov khw xws li Kapp Alloy.
Kauj Ruam 3. Npaj cov chaw
Cov kabmob ntawm qhov chaw feem ntau yog ntxuav nrog cov kuab tshuaj kom tshem tawm cov roj lossis lwm yam kab mob paug. Ntawm qhov hnav zoo thiab zoo nkauj qub, qhov no tuaj yeem yog qhov nyuaj tshaj plaws ntawm kev kho dua tshiab. Feem ntau, cov roj nplua nyeem thiab cov paug tau ua haujlwm zoo rau cov hlau thiab cov kabmob qub Babbitt. Tej zaum koj yuav pom tias koj xav tias qhov huv yog huv, tab sis ntawm cua sov, muaj ntau cov kab mob thiab cov nplaim roj los ntawm cov hlau. Cov kab mob sib kis no tuaj yeem rub tawm los ntawm kev hloov pauv: a. cua sov thaum txhuam nrog txhuam txhuam cov hlau tsis huv, thiab b. kev kho hnyav. Kev tshem tawm cov kab mob no yog qhov tseem ceeb rau kev sib koom ua ke Babbitt. Nco ntsoov tias lub hau kom tau txais kev txhawb nqa los ntawm cov kabmob yog du thiab huv.
Kauj Ruam 4. Tsho lub hau
Txhawm rau tiv thaiv tus ncej kom tsis txhob los ntawm cov kabmob, npog lub hau nrog cov pa luam yeeb los ntawm cov nplaim taws qis roj lossis roj tswm ciab.
Kauj Ruam 5. Muab cov ntu tso rau
Muab lub plhaub kabmob tso rau hauv txoj haujlwm ntsug. Teem tus ncej nyob hauv nruab nrab ntawm lub plhaub kabmob. Plug lossis dam lub qhov nyob rau hauv cov kabmob, tshwj tsis yog lub qhov taub. Av, ntoo, ntawv hlau thiab cov hluav taws kub tiv thaiv hluav taws tuaj yeem siv tau los ntsaws qhov.
Kauj Ruam 6. Qhuav cov hlau Babbitt
Siv cov hlau cam khwb cia hlau yaj yaj. Ua kom sov Babbitt hlau mus rau qhov xav tau kub nyob ntawm seb Babbitt alloy. Lub lauj kaub hluav taws xob uas tsim los pov cov mos txwv yog qhov nyiam tshaj vim tias lub lauj kaub muaj qhov ntsuas kub. Cov suab nrov feem ntau muaj nyob rau ntawm cov khw muag khoom ua tub rog thiab tshwj xeeb forging khw. Cov qhov hluav taws xob no tseem yuav tsum muaj peev xwm muab lub mos txwv caster tus pas ntsuas kub, uas yog siv los xyuas kom meej tias Babbitt hlau nyob ntawm qhov xav tau kub.
Kauj Ruam 7. Ua kom sov cov kabmob thiab lub hau
Qhov no yuav txo qis qhov kub poob thaum nchuav thiab ua kom cov khoom tsim nyog thiab ua tau zoo ib yam. Ua kom sov lub plhaub thiab lub taub hau kom txog 250 degrees F (121 degrees C) kom cov dej noo tuaj sai sai, tab sis tsis yog sputter.
Kauj Ruam 8. Skim ntxuav cov hlau Babbitt uas tau yaj
Thaum cov hlau Babbitt tau mus txog qhov ntsuas kub kom raug, do cov kua. Skim tawm ib qho quav (impurities) uas tau ntab mus rau saum cov hlau yaj.
Kauj Ruam 9. Ncuav cov kabmob
Ncuav cov hlau Babbitt molten rau hauv lub plhaub kabmob. Yog tias tus nais dej tsis loj txaus los sau nrog 1 nphoo, ua haujlwm sai kom tau txais lub ncuav thib ob txhawm rau kom tsis muaj daim ntawv ciam teb nruab nrab ntawm 2 nphoo.
Kauj Ruam 10. Ua kom tiav cov kabmob
Cia cov kabmob kom txias tag nrho. Siv lub laum los laum cov roj qhov. Ntxuav cov khoom siv ntau dhau los ntawm qhov drilling. Siv pob zeb zoo li tus txiab txov cov roj zawj los ntawm cov roj qhov kom txog li 0.25 ntiv tes (6.35 mm) los ntawm qhov kawg ntawm cov kabmob. Cov roj ziab khaub ncaws yuav tsum tau txiav rau sab hauv ntawm cov kabmob, yog li cov kabmob yuav tsum tau tsav tawm ntawm tus ncej rau chiseling thiab tom qab ntawd hloov. Ntxuav ib yam khoom uas tshuav los ntawm chiseling.
Lus ceeb toom
- Hnav khaub ncaws tiv thaiv. Cov hlau ua haujlwm ua haujlwm zoo, lub ntsej muag tiv thaiv thiab hnab looj tes tiv thaiv yuav tsum hnav thaum tuav cov hlau kub.
- Ntxuav tes kom huv tom qab ua tiav. Cov tshuaj lom lom tso tawm thaum lub sij hawm yaj ntawm Babbitt hlau tuaj yeem lo rau ntawm koj txhais tes. Tsis txhob noj ua ntej ntxuav koj txhais tes thaum ua cov txheej txheem no.
- Melted Babbitt hlau yuav tsum tau ua tib zoo ua haujlwm, tshwj xeeb yog tias muaj caij nyoog yuav kis tau cov dej noo. Cov dej noo yuav tsim kom tawg sai sai uas yuav ua rau cov hlau Babbitt yaj. Kev sib tsoo ntawm cov hlau Babbitt yaj yuav ua rau raug mob hnyav thiab yuav yog qhov phom sij txaus ntshai.
- Qhuav cov hlau Babbitt hauv qhov chaw muaj cua nkag tau zoo. Cov pa lom tuaj yeem tso tawm thaum yaj.
