Ib txoj saw hlau ua li cas thiaj tswj tau nws txoj kev ua tau zoo hauv qhov chaw kub siab?
Nws yog ib qho tseem ceeb heev uas yuav tsum tswj hwm kev ua haujlwm ntawm cov saw hlau hauv qhov chaw kub siab vim tias nws siv dav hauv cov khoom siv kub siab xws li cov cub tawg thiab cav, thiab kev ua haujlwm ib txwm ntawm cov khoom siv no nyob ntawm kev ua haujlwm ruaj khov ntawm cov saw hlau. Cov hauv qab no yog cov kev ntsuas tseem ceeb los tswj hwm kev ua haujlwm ntawm cov saw hlau hauv qhov chaw kub siab:
Kev xaiv khoom thiab kev kho mob
1. Xaiv cov khoom siv uas tiv taus kub heev
Kev xaiv cov khoom siv ntawm cov saw hlau yog lub hauv paus rau kev tswj hwm lawv cov kev ua tau zoo hauv qhov chaw kub siab. Cov khoom siv tiv taus kub siab feem ntau suav nrog cov hlau sib xyaw thiab cov hlau tsis xeb. Cov hlau sib xyaw tuaj yeem txhim kho nws cov cua sov thiab kev tiv taus oxidation los ntawm kev ntxiv cov khoom sib xyaw xws li nickel thiab chromium, yog li nws tseem tuaj yeem tswj tau lub zog zoo thiab tawv ntawm qhov kub siab. Cov saw hlau tsis xeb muaj qhov zoo ntawm kev tiv taus acid, alkali, txias thiab kub, thiab siv dav hauv qhov kub siab thiab qis. Piv txwv li, qee cov saw hlau kub siab siv cov khoom sib xyaw tshwj xeeb uas tuaj yeem tswj tau lubrication ruaj khov thiab hnav cov yam ntxwv hauv qhov kub ntawm -10 ℃ txog 230 ℃
2. Cov txheej txheem kho cua sov
Cov txheej txheem kho cua sov tuaj yeem txhim kho cov qauv me me thiab cov khoom siv kho tshuab ntawm cov khoom siv saw hlau thiab hloov kho lawv rau qhov chaw kub siab. Cov txheej txheem kho cua sov feem ntau suav nrog kev annealing, kev kho cov tshuaj, kev kho laus, kev ua kom zoo li qub thiab kev quenching. Piv txwv li, kev quenching lub phaj saw hlau ntawm cov saw hlau tuaj yeem txhim kho nws qhov nyuaj ntawm qhov chaw thiab kev tiv thaiv kev hnav, ua rau nws tsis yooj yim hnav thiab deformation ntawm qhov kub siab. Tsis tas li ntawd, kev kho cua sov tuaj yeem tshem tawm kev ntxhov siab hauv cov khoom siv thiab tiv thaiv kev puas tsuaj los ntawm kev ntxhov siab thermal hauv qhov chaw kub siab.
Kev siv roj nplua nyeem thiab kev txij nkawm
1. Siv cov roj nplua nyeem uas tiv taus kub siab
Cov roj nplua nyeem ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov saw hlau, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kub siab. Cov roj nplua nyeem uas tiv taus kub siab tuaj yeem tswj tau qhov ua tau zoo ntawm qhov kub siab thiab tsis yooj yim yaj lossis lwj. Piv txwv li, kev siv cov roj nplua nyeem qib NSF-H1 tsis yog tsuas yog haum rau qhov chaw kub siab xwb, tab sis kuj muaj kev ua tau zoo heev thaum cov saw hlau nyuaj rau muab roj. Tsis tas li ntawd, cov roj nplua nyeem tuaj yeem tsim ib daim zaj duab xis tiv thaiv rau ntawm qhov chaw ntawm cov saw hlau, txo qhov sib txhuam thiab kev hnav, thiab txuas ntxiv lub neej kev pabcuam ntawm cov saw hlau.
2. Kev saib xyuas thiab kev tshuaj xyuas tsis tu ncua
Kev saib xyuas thiab tshuaj xyuas cov saw hlau tsis tu ncua yog ib qho tseem ceeb kom ntseeg tau tias lawv ua haujlwm tau zoo hauv qhov chaw kub siab. Kev saib xyuas suav nrog kev ntxuav cov roj thiab cov khoom tsis huv ntawm qhov chaw ntawm cov saw hlau, tshuaj xyuas qhov nruj thiab hnav ntawm cov saw hlau, thiab kho thiab hloov cov khoom uas hnav hnyav raws sijhawm. Piv txwv li, cov saw hlau yuav ntev vim yog hnav thaum lub sijhawm ua haujlwm. Thaum cov saw hlau ntev dhau ntau tshaj 3%, cov saw hlau yuav tsum tau hloov raws sijhawm. Kev tshuaj xyuas tsis tu ncua kuj tseem tuaj yeem pom cov teeb meem uas yuav tshwm sim, xws li khoov thiab ntswj ntawm cov saw hlau, kom tiv thaiv cov teeb meem loj xws li tawg hauv qhov chaw kub siab.
Kev tsim qauv zoo tshaj plaws
1. Txhim kho lub zog tensile ntawm cov saw hlau
Nyob rau hauv qhov chaw kub siab, lub zog ntawm cov saw hlau yuav raug cuam tshuam rau qee qhov, yog li nws yog qhov tsim nyog los txhim kho nws lub zog tensile los ntawm kev tsim qauv. Piv txwv li, nce qhov tuab ntawm lub phaj saw hlau sab hauv kom ntseeg tau tias lub zog tensile ntawm cov saw hlau. Tsis tas li ntawd, cov koob thiab cov tes tsho muaj zog siab tuaj yeem siv los txhim kho lub peev xwm thauj khoom ntawm cov saw hlau. Cov koob muaj zog siab tuaj yeem xa lub zog zoo dua, thaum cov tes tsho yuav tsum muaj kev tiv thaiv kev hnav zoo thiab cov nyhuv lubrication.
2. Xav txog cov yam ntxwv ntawm kev nthuav dav thermal
Hauv qhov chaw kub siab, qhov coefficient ntawm thermal expansion ntawm cov saw hlau yuav hloov pauv, uas yuav ua rau muaj teeb meem xws li qhov loj ntawm cov saw hlau tsis sib xws thiab kev ntxhov siab. Yog li ntawd, thaum tsim cov saw hlau, nws yog ib qho tsim nyog los xav txog qhov thermal expansion factor, npaj qhov pitch thiab ntev ntawm cov saw hlau kom zoo, thiab xyuas kom meej tias qhov ntev thiab qhov tseeb ntawm cov saw hlau ntawm qhov kub siab. Piv txwv li, rau cov saw hlau stainless, thaum qhov kub ntawm ib puag ncig tshaj 400 ° C, yuav tsum tau them sai sai rau qhov sib txawv ntawm qhov tshwm sim los ntawm thermal expansion.
Kev hloov pauv ib puag ncig zoo dua
1. Kev tiv thaiv kev oxidation thiab kev tiv thaiv kev xeb
Qhov kub thiab txias yuav ua rau cov txheej txheem oxidation thiab corrosion ntawm cov saw hlau ua kom nrawm dua, yog li yuav tsum tau ua cov kev tiv thaiv oxidation thiab tiv thaiv corrosion. Piv txwv li, kev kho qhov chaw ntawm cov saw hlau, xws li nickel plating, Dacromet, phosphating, thiab lwm yam, tuaj yeem tsim ib txheej tiv thaiv kom tiv thaiv oxidation thiab corrosion ntawm qhov kub thiab txias. Tsis tas li ntawd, ib txheej tiv thaiv oxidation tuaj yeem siv rau ntawm qhov chaw ntawm cov saw hlau kom txhim kho nws qhov kev tiv thaiv kub siab.
2. Tsim tshwj xeeb los hloov kho rau qhov chaw ib puag ncig hnyav
Nyob rau hauv qhov chaw kub siab, cov saw hlau kuj tseem yuav ntsib lwm yam mob hnyav, xws li dej noo, plua plav, roj, thiab lwm yam. Yog li ntawd, cov saw hlau yuav tsum muaj kev hloov pauv zoo rau ib puag ncig. Piv txwv li, tsim cov qauv saw hlau nrog kev ua haujlwm zoo sealing kom tiv thaiv cov plua plav thiab roj nkag mus rau hauv cov saw hlau thiab cuam tshuam rau nws txoj haujlwm ib txwm. Tib lub sijhawm, cov txheej txheem lubrication tshwj xeeb xws li roj da dej lubrication lossis lub voj voog siab lubrication kuj tseem siv tau los hloov kho rau qhov kub siab thiab ib puag ncig hnyav.
Kev Txheeb Xyuas
Tus yuam sij rau kev tswj hwm kev ua tau zoo ntawm cov saw hlau hauv qhov chaw kub siab yog nyob rau hauv kev ntsuas dav dav xws li kev xaiv thiab kev ua cov khoom siv, kev ua kom lubrication thiab kev saib xyuas, kev tsim qauv zoo tshaj plaws, thiab kev txhim kho kev hloov pauv ib puag ncig. Los ntawm kev xaiv cov khoom siv tiv taus kub siab, kev siv cov txheej txheem kho cua sov kom zoo, siv cov roj nplua nyeem tiv taus kub siab, kev saib xyuas thiab kev tshuaj xyuas tsis tu ncua, txhim kho lub zog tensile ntawm cov saw hlau, xav txog cov yam ntxwv nthuav dav thermal, kev siv cov kev ntsuas tiv thaiv oxidation thiab tiv thaiv corrosion, thiab cov qauv tsim tshwj xeeb hloov kho rau qhov chaw kub hnyav, cov saw hlau tuaj yeem tswj hwm kev ua tau zoo ruaj khov hauv qhov chaw kub siab, ua kom ntseeg tau tias kev ua haujlwm ib txwm ntawm cov khoom siv kho tshuab thiab kev nce qib ntawm kev tsim khoom lag luam. Nrog rau kev txhim kho tas mus li ntawm cov ntaub ntawv tshawb fawb thiab kev siv tshuab, kev ua tau zoo ntawm cov saw hlau hauv qhov chaw kub siab yuav raug txhim kho ntxiv, muab kev lees paub ntau dua rau kev ua haujlwm ntawm cov khoom siv kub siab.
