Ib, Kev sib txuas ntawm pwm lub neej thiab hnav tsis kam
Txhaj pwmrau cov khoom siv hluav taws xob yuav tsum muaj peev xwm tswj tau ntau lub siab thiab hnav los ntawm cov yas yaj hauv lub sijhawm ntev. Yog tias cov khoom siv los ua cov pwm tsis muaj qhov hnav tsis txaus, nws yooj yim rau khawb lossis ua kom nrawm ntawm qhov hnav ntawm cov pwm, uas hloov cov khoom zoo thiab zoo.
Qee cov khoom siv pwm uas tsis hnav yooj yim yog H13, S136, P20, thiab lwm yam hlau uas tuaj yeem nyob ruaj khov thiab tsis hnav txawm tias thaum kub thiab ua rau muaj kev kub ntxhov ntau. Yog tias koj xaiv cov khoom uas tsis hnav yooj yim, cov pwm yuav kav ntev dua, xav tau kev tu kom tsawg, thiab raug nqi tsawg dua los ua.
2, Yuav ua li cas thermal conductivity cuam tshuam cov txheej txheem ntawm kev txhaj tshuaj casting
Yuav ceev npaum li cas thiab ntev npaum li cas nws yuav siv sij hawm rau cov yas yaj kom txias yog nyob ntawm seb cov ntaub ntawv siv los ua cov pwm zoo li cas rau cov khoom siv hluav taws xob ua kom sov. Thaum cov khoom siv tsis ua cua sov zoo, lawv tuaj yeem ua rau qhov txias tsis sib xws thiab ua rau cov khoom muaj feem cuam tshuam, ntsws, lossis muaj kev ntxhov siab.
Txhawm rau kom paub tseeb tias qhov zoo ntawm kev txhaj tshuaj-moulded qhov chaw rau cov khoom siv hluav taws xob, tib neeg feem ntau xaiv cov hlau lossis cov hlau nplaum uas zoo rau kev hloov cov cua sov, xws li tooj liab-raws li alloys lossis pwm inserts uas yog plated nrog tooj liab. Qhov no tuaj yeem ua kom cov txheej txheem hloov cov cua sov thiab ua kom cov khoom siv tau zoo dua. Tib lub sijhawm, lub qhov dej -xav- tawm qhov cua txias yog lwm txoj hauv kev tseem ceeb kom paub tseeb tias cov pwm tuaj yeem hloov tau cov cua sov zoo.
3, Kev ua tau zoo hauv kev ua thiab teeb meem ua pwm
Txhaj pwm rau cov khoom siv hluav taws xob feem ntau muaj cov qauv tsim thiab yuav tsum tau ua kom meej heev. zoo npaum li cas cov ntaub ntawv pwm ua haujlwm rau kev ua haujlwm yog lwm qhov tseem ceeb uas yuav tsum tau xav txog thaum koj xaiv. Nws yog ib qho yooj yim rau zeb, laum, hlau txiav, thiab polish cov ntaub ntawv uas zoo ntawm kev ua. Qhov no tuaj yeem txo lub sijhawm nws siv los ua tus qauv thiab txo tus nqi ntawm kev ua haujlwm.
P20 steel yog ib qho yooj yim rau kev ua hauj lwm nrog thiab polish, uas ua rau nws zoo rau feem ntau me me thiab nruab nrab -cov khoom siv hluav taws xob txhaj tshuaj pwm. High- cov ntaub ntawv hardness zoo li S136 tiv taus hnav, tab sis lawv nyuaj rau kev ua haujlwm nrog thiab xav tau cov cuab yeej machining thiab cov txheej txheem.
4, Kev tiv thaiv corrosion thiab zoo ntawm pwm nto
Txhaj pwm rau cov khoom siv hluav taws xob yog nyob rau hauv kev sib cuag nrog cov yas yaj rau lub sijhawm ntev. Qee cov yas muaj cov tshuaj ntxiv lossis cov xim uas muaj corrosive. Yog tias cov khoom siv pwm tsis muaj kev tiv thaiv corrosion txaus, nws tuaj yeem xeb lossis puas tsuaj, uas hloov cov khoom zoo li cas thiab ua rau cov pwm lub neej luv.
Yog tias koj xaiv cov ntaub ntawv uas tsis xeb, xws li S136 thiab 420 stainless hlau, los yog kho cov pwm saum npoo nrog chrome plating, npib tsib xee plating, los yog ib yam dab tsi zoo sib xws, koj tuaj yeem nres corrosion thiab xyuas kom meej tias qhov kev txhaj tshuaj - cov pwm yog du thiab raug. Qhov no ua haujlwm tshwj xeeb tshaj yog rau cov pwm uas yuav tsum tau saib zoo ntawm cov khoom siv hluav taws xob.
5, Ua tib zoo xav txog tus nqi thiab kev siv
Tus nqi yog lwm qhov tseem ceeb uas tsis tuaj yeem tsis quav ntsej thaum xaiv cov khoom siv pwm rau cov khoom siv thev naus laus zis. Cov ntaub ntawv nrog ntau hardness, tsis kam hnav, thiab tiv thaiv corrosion raug nqi ntau, tab sis lawv tuaj yeem kav ntev dua thiab xav tau kev tu kom tsawg. Cov neeg siv yuav tsum ua tib zoo xaiv cov khoom uas lawv siv los ntawm kev coj mus rau hauv tus account qhov loj ntawm cov khoom batch, hom yas, shaping tej yam kev mob, thiab qhov chaw uas yuav siv pwm.
P20 lossis 718 steel tuaj yeem siv rau cov khoom me me ntawm kev tsim khoom lossis cov khoom yas uas tsis tas yuav muaj zog heev. Rau qhov ntim ntau lawm los yog qhov chaw uas yuav tsum tau txhaj tshuaj ntawm qhov kub thiab txias, nws yog qhov zoo tshaj plaws los siv siab - cov ntaub ntawv ua tau zoo xws li H13 lossis S136 kom cov pwm ruaj khov thiab ua kom cov khoom zoo.
