Nyob rau theem no, Tuam Tshoj cov hlau tsim tawm tau ua kom zoo dua txuas ntxiv, thiab cov peev xwm tsim tau ntau zuj zus. Ua kom tau los ntawm cov khoom siv ntau ntawm cov cuab yeej siv hlau, ntau zaus siv tau dhau los ua qhov loj dua thiab muaj zog dua qub. Yog li, cov cuab yeej yuav muaj teeb meem ntau yam hauv kev ua haujlwm. Txhawm rau kom muaj qhov ruaj khov ntawm cov peev xwm tsim tawm, nws yog qhov tshwj xeeb rau kev saib xyuas thiab kho cov cuab yeej. Cov khoom siv dov yog cov cuab yeej tseem ceeb hauv kev lag luam steel, thiab cov kabmob hav zoov yog ib qho tseem ceeb ntawm cov khoom siv no, uas yog qhov tsim nyog rau nws txoj haujlwm nyab xeeb thiab ruaj khov. Rau cov khoom siv cuam tshuam nrog kev lag luam rolling tshuab, nws muaj lub peev xwm thauj khoom siab dua, kev ua haujlwm qis dua thiab ua haujlwm siab dua. Yog li, cov kabmob ntawm cov khoom siv hauv kev lag luam dov hlau feem ntau xyuas cov khoom sib xyaw nrog cov kabmob hav zoov hauv kev kuaj xyuas thiab kev kho, thiab kho thiab daws cov teeb meem ua ke nrog cov teeb meem saum toj no.
1. Lub cev tsis zoo thiab cov hau kev kho mob hauv kev tshuaj xyuas cov txheej txheem hav zoov ntawm cov dov hlau tshuab
Cov kabmob hav txwv yeem ua los ntawm babbitt alloy yog txawv ntawm lwm cov ntaub ntawv, thiab muaj muaj zog hnav tsis kam thiab wearability thiab kev sib txhuam tsis kam. Ntawm chav tsev kub, lub zog txaus thiab ua rau kev sib txhuam kuj zoo tagnrho. Nyob rau tib lub sijhawm, txheej txheem thev naus laus zis ntawm cov kabmob hav zoov tau zoo, thiab muaj cov thermal conductivity zoo, thiab cov coefficient ntawm thermal expansion tsis loj, thiab muaj qee yam kev txhim kho corrosion. Los ntawm kev txheeb xyuas thiab kev tshawb fawb txog kev siv tiag tiag ntawm cov hav txwv yeem, nws tuaj yeem nkag siab tias qhov teeb meem loj tshaj plaws ntawm kev siv babbitt bearing Bush yog hnav, thiab qhov ua rau tsis muaj xwm txheej ua rau cov kabmob hav zoov txhawm thiab hlawv. Yog li no, peb yuav tsum them sai sai rau kev saib xyuas kev ua haujlwm ntawm lub cev hav zoov thiab txuas ntxiv nws lub neej kev pab. Txawm li cas los xij, hauv cov haujlwm txij nkawm tiag tiag, muaj ib txwm muaj qhov tsis xws luag, yog li nws yog qhov tseem ceeb heev los soj ntsuam cov txheej txheem txij nkawm hauv kev nthuav dav thiab hais tawm qhov kev ntsuas ua tau.
(1) Kev tsis zoo thiab kev tiv thaiv ntawm cov txheej txheem casting. Tom qab pov cov kabmob hav zoov, casting tsis xws luag yuav tshwm sim vim qhov tsis muaj zog adhesion ntawm Babbitt alloy tiv thaiv kev txhuam txheej thiab cov kabmob bushing. Lub ntsiab loj vim li cas yog tias qhov kev npaj tsis txhij. Kev ntxuav tag nrho ntawm cov kabmob txheej kuj tseem yog vim qhov teeb meem ntawm kev tiv thaiv tsis sib haum, yog li nws yuav tsum tau npaj ua ntej. Nyob rau tib lub sijhawm, cov kabmob yuav tsum tau ntxuav hauv qhov tob thiab degreased siv high-temperature alkaline dej rhaub. Tom qab ziab, nws yog qhov yuav tsum tau siv cov tshuaj tov uas tov nrog zinc chloride txhawm rau txhuam hauv qhov cua sov tshwj xeeb los pab txhawb cov txheej txheej kom cov hlua dai, tab sis nws yog qhov tsim nyog los xyuas kom cov tuab ntawm tin, thiab kom muaj kev sib luag.
(2) Qhov tsis zoo saum npoo thiab kev kho mob ntawm cov kabmob alloys. Rau sab hauv ntawm cov kabmob alloys, teeb meem xws li slag suav nrog, qhov hws thiab shrinkage qhov yog qhov yooj yim rau muaj, yog li nws yuav muaj qee yam cuam tshuam rau ntau yam xws li alloy muaj pes tsawg leeg thiab casting kub. Vim tias pwm txheej txheem thiab txheej txheem ntawm dov zeb coj los ua hav zoov yog qhov yooj yim heev, tab sis qhov kub thiab txias yuav ua lub luag haujlwm txiav txim siab rau qhov zoo casting, yog li qhov ntsuas kub thiab kev ua haujlwm zoo sib npaug. Thaum qhov kub siab dhau lawm, qhov teeb meem ntawm porosity, shrinkage lossis shrinkage yuav tshwm sim. Yog li, qhov kub tau tswj tau kom zoo, thiab qhov ntsuas kub tau yoog raws li qhov muaj peev xwm sau tau zoo.
(3) Cov khoom siv ntawm cov ntaub qhwv cov kabmob yog hnav lossis swb. Rau kev siv lub tshuab dov, nws tus kheej thauj khoom muaj feem siab thiab khiav ceev yog tsawg. Yog li ntawd, nyob rau hauv txoj kev ua haujlwm tiag tiag, nws yog ib qho yooj yim rau tus ncej thiab cov kabmob hav txwv yeem kom nyob rau hauv ib lub xeev tsis tiav. Tsis tas li ntawd, muaj kev sib txhuam ncaj qha rau ntawm tus ncej thiab cov kabmob hav txwv yeem, thiab khawb ntawm qhov chaw sib chwv yog ntxhib. Nyob rau hauv cov xwm txheej no, yog tias nws nyob hauv lub xeev ntawm lub siab thiab lub cev yas deformation, kev hloov pauv ntawm lub cev yuav tsis tuaj yeem tshwm sim, thiab thaum kawg lub hauv paus hlau yuav ua raws. Cov. Hauv cov xwm txheej no, kev txiav plaub hau yuav tsis tshwm sim. Txawm li cas los xij, cov nplej abrasive ntawm cov khoom siv alloy yuav kuj tig rov qab. Yog tias qhov no yog lub sijhawm ntev, qhov saum npoo ntawm cov kabmob pad yuav ua raws li cov txheej txheej abrasive ntawm cov khoom siv alloy, thiab tom qab ntawd tus qauv ntawm cov kabmob hav zoov nws tus kheej. Daim duab yog raug puas tsuaj thiab muaj teeb meem ntawm lub zog tsis sib xws. Nyob rau tib lub sijhawm, zaj duab xis roj lubricating tseem yuav muaj cov yam ntxwv, yog li cov kabmob hav zoov kub dhau lawm thiab raug hlawv. Yog li no, peb yuav tsum xyuas kom meej tias cov kabmob hav txwv yeem nyob hauv lub xeev ntawm lubrication. Yog tias pom tau deformation, nws yuav tsum ua qhov ntsuas kom raws sij hawm los ua nws.
(4) Cov kabmob khawb cuam tshuam cuam tshuam kev kho mob lubricity, vim tias lub zog ua haujlwm siab roj roj los ntawm lub pob zeb ua haujlwm tsis zoo, thiab cov roj nplua nyeem zaj duab xis nyob nruab nrab ntawm tus ncej thiab cov kabmob hav zoov tsis tau raws li qhov yuav tsum tau ua, nws yuav overheated thaum tus coj cov hav txwv yeem khiav. Cuam tshuam thiab hnav, uas nyeg muaj qhov tsis zoo rau kev ua haujlwm ntawm lub tshuab dov. Yog li no, cov roj nqus ntawm cov kabmob hav txwv yeem tswj tau zoo kom ntseeg tau cov haujlwm ntawm cov kabmob hav txwv yeem thiab ntev lub neej kev pab tiag tiag. Txhawm rau kom ntseeg tau tias qhov tseeb thiab meej ntawm cov kabmob scraping, nws yuav tsum xyuas kom meej tias lub peev xwm muaj peev xwm ntawm cov kabmob hav txwv yeem yog yam tsis sib xws, thiab thaj chaw cov kabmob yuav tsum muaj ntsis. Tsuas yog thaum cov npoo ntawm cov roj lubricating thiaj li ua kom du, qhov zoo ntawm cov roj zaj duab xis tuaj yeem ua kom zoo.
