Yuav ua li cas lub neej hnav ntawm cov saw hlau yuav luv dua nyob rau hauv cov chaw muaj plua plav?
Raws li ib qho khoom siv kis tau dav siv hauv ntau yam khoom siv kho tshuab, lub neej hnav ntawmcov saw hlauraug cuam tshuam los ntawm ntau yam, thiab ib puag ncig muaj plua plav yog ib qho tseem ceeb tshaj plaws. Hauv cov chaw muaj plua plav, lub neej hnav ntawm cov saw hlau yuav luv dua, tab sis qib tshwj xeeb ntawm kev luv luv nyob ntawm ntau yam, suav nrog hom, concentration, qhov loj me ntawm cov hmoov av, thiab kev saib xyuas saw hlau.
Mechanism ntawm kev cuam tshuam ntawm cov hmoov av rau kev hnav cov saw hlau
Cov nyhuv abrasive ntawm cov hmoov av me me:
Cov hmoov av yuav nkag mus rau qhov chaw sib cuag ntawm cov saw thiab lub sprocket ntawm cov saw hlau, ua haujlwm ua tus txhuam thiab ua kom cov saw thiab sprocket hnav sai dua. Qhov kev txhuam no yuav ua rau qhov chaw ntawm cov menyuam, bushings, thiab cov phaj saw hlau maj mam hnav, txo qhov tseeb thiab lub zog ntawm cov saw hlau.
Qhov tawv thiab cov duab ntawm cov hmoov av me me kuj tseem yuav cuam tshuam rau qib kev hnav. Cov hmoov av uas muaj qhov tawv dua (xws li xuab zeb quartz) yuav ua rau cov saw hlau hnav hnyav dua.
Kev ua qias tuaj ntawm cov roj nplua nyeem thiab kev ua tsis tiav:
Cov khoom me me nyob rau hauv ib puag ncig muaj plua plav tuaj yeem sib xyaw rau hauv cov roj nplua nyeem ntawm cov saw hlau, ua rau muaj kuab paug rau cov roj nplua nyeem. Cov roj nplua nyeem uas muaj kuab paug tsis yog tsuas yog poob lawv cov txiaj ntsig ntawm kev nplaum xwb, tab sis kuj ua rau cov saw hlau puas tsuaj ntxiv.
Kev ua qias tuaj ntawm cov roj nplua nyeem kuj tseem tuaj yeem ua rau xeb thiab qaug zog rau cov saw hlau, ua rau nws lub neej ua haujlwm luv dua.
Cov teeb meem plua plav thiab cua sov dissipation:
Cov hmoov av me me yuav thaiv cov qhov roj nplua nyeem thiab cov qhov cua sov ntawm cov saw hlau, cuam tshuam rau kev ua kom cov roj nplua nyeem thiab cua sov ntawm cov saw hlau tsis tu ncua. Qhov no yuav ua rau cov saw hlau kub thaum lub sijhawm ua haujlwm, ua rau cov khoom siv saw hlau laus thiab qaug zog sai dua.
Qib tshwj xeeb ntawm kev siv lub neej luv dua
Raws li kev tshawb fawb thiab cov ntaub ntawv siv tiag tiag, nyob rau hauv ib puag ncig muaj plua plav, lub neej siv ntawm cov saw hlau yuav luv dua li 1/3 lossis tsawg dua ntawm qhov ntawd hauv ib puag ncig huv si. Qhov degree ntawm kev luv luv nyob ntawm cov hauv qab no:
Cov plua plav ntau heev: Ib puag ncig muaj plua plav ntau heev yuav ua rau cov saw hlau hnav sai dua. Yog tias muaj plua plav ntau heev, lub neej siv ntawm cov saw hlau yuav luv dua li 1/2 txog 1/3 ntawm qhov ntawd hauv ib puag ncig muaj plua plav tsawg.
Qhov loj ntawm cov hmoov av me me: Cov hmoov av me me yuav nkag mus rau qhov chaw sib cuag ntawm cov saw hlau thiab ua rau hnav ntau dua. Cov hmoov av me me uas muaj qhov loj me tsawg dua 10 microns muaj qhov cuam tshuam loj tshaj plaws rau kev hnav ntawm cov saw hlau.
Kev saib xyuas cov saw hlau: Kev ntxuav thiab roj tsis tu ncua ntawm cov saw hlau tuaj yeem txo qhov cuam tshuam ntawm cov hmoov av rau ntawm cov saw hlau thiab ua kom nws lub neej ua haujlwm ntev dua. Lub neej hnav ntawm cov saw hlau uas tsis tau saib xyuas tsis tu ncua hauv qhov chaw muaj hmoov av yuav raug luv dua li 1/5 ntawm nws lub neej hauv qhov chaw huv si.
Cov kev ntsuas los txuas lub neej siv ntawm cov saw hlau
Xaiv cov khoom siv saw hlau kom raug:
Siv cov ntaub ntawv uas tiv taus kev hnav zoo dua, xws li hlau alloy lossis hlau stainless, tuaj yeem ua rau lub neej ua haujlwm ntawm cov saw hlau ntev dua hauv qhov chaw muaj plua plav.
Cov txheej txheem kho qhov chaw, xws li nickel plating lossis chrome plating, kuj tseem tuaj yeem txhim kho qhov hnav tsis kam thiab corrosion tsis kam ntawm cov saw hlau.
Txhim kho qhov kev tsim qauv ntawm cov saw hlau:
Siv cov qauv saw hlau uas muaj kev ua haujlwm zoo dua, xws li cov qauv labyrinth thiab cov ntsaws ruaj ruaj, tuaj yeem tiv thaiv cov hmoov av kom tsis txhob nkag mus rau hauv cov saw hlau thiab txo qhov hnav.
Kev ua kom cov qhov roj nplua nyeem thiab cov qhov cua sov ntawm cov saw hlau nce ntxiv tuaj yeem txhim kho cov nyhuv ntawm cov roj nplua nyeem thiab cua sov ntawm cov saw hlau thiab ua kom nws lub neej ua haujlwm ntev dua.
Txhim kho kev saib xyuas saw hlau:
Ntxuav cov saw hlau tas li kom tshem tawm cov hmoov av thiab av qias neeg ntawm qhov chaw, uas tuaj yeem txo qhov cuam tshuam ntawm cov hmoov av rau ntawm cov saw hlau.
Tshawb xyuas thiab hloov cov roj nplua nyeem tas li kom ntseeg tau tias cov saw hlau muaj roj nplua nyeem zoo, uas tuaj yeem txo qhov hnav.
Siv cov khoom siv tiv thaiv plua plav:
Kev txhim kho lub hau npog plua plav lossis lub cuab yeej kaw ib puag ncig cov saw hlau tuaj yeem txo qhov cuam tshuam ntawm cov plua plav rau ntawm cov saw hlau.
Siv cov hau kev xws li tshuab cua lossis nqus tsev tuaj yeem txo qhov kev ua qias tuaj ntawm cov hmoov av ntawm cov saw hlau.
Kev tshuaj xyuas cov neeg mob
Rooj plaub 1: Daim ntawv thov ntawm cov saw hlau hauv cov tshuab mining
Hauv cov tshuab khawb av, cov saw hlau feem ntau siv rau hauv kev thauj khoom thiab cov khoom siv khawb av. Vim muaj cov hmoov av ntau hauv qhov chaw khawb av, lub neej hnav ntawm cov saw hlau luv dua. Los ntawm kev siv cov saw hlau alloy uas muaj kev tiv thaiv kev hnav zoo dua thiab kev ntxuav thiab lubrication tsis tu ncua, lub neej hnav ntawm cov saw hlau tau ntev dua los ntawm 3 lub hlis thawj mus rau 6 lub hlis, uas ua rau kev ua haujlwm ntawm cov khoom siv zoo dua.
Rooj Plaub 2: Kev siv cov saw hlau hauv cov chaw cog cement
Hauv cov chaw tsim cement, cov saw hlau siv rau kev xa khoom thiab kis cov khoom siv. Vim tias cov hmoov av cement tawv heev, qhov teeb meem hnav ntawm cov saw hlau yog qhov hnyav heev. Los ntawm kev siv cov qauv saw hlau nrog kev ua haujlwm zoo dua thiab kev teeb tsa lub hau plua plav, lub neej hnav ntawm cov saw hlau tau ntev dua los ntawm 2 lub hlis thawj mus rau 4 lub hlis, ua rau txo cov nqi kho ntawm cov khoom siv.
Xaus lus
Lub neej siv ntawm cov saw hlau hauv qhov chaw muaj plua plav yuav luv dua, thiab qib luv dua nyob ntawm cov yam xws li hom, qhov sib xyaw, qhov loj ntawm cov hmoov av thiab kev saib xyuas ntawm cov saw hlau. Los ntawm kev xaiv cov ntaub ntawv saw hlau tsim nyog, kev ua kom zoo dua ntawm kev tsim qauv ntawm cov saw hlau, kev txhawb nqa kev saib xyuas ntawm cov saw hlau thiab siv cov khoom siv tiv thaiv plua plav, lub neej siv ntawm cov saw hlau hauv qhov chaw muaj plua plav tuaj yeem ntev dua, thiab kev ua haujlwm zoo thiab kev ntseeg siab ntawm cov khoom siv tuaj yeem txhim kho.
