Dab tsi yog qhov txawv ntawm cam khwb cia thiab forged li qub?
Valves ua lub luag haujlwm tseem ceeb hauv kev tswj cov dej ntws hauv cov kav dej, cov tshuab ua haujlwm, thiab lwm yam kev siv. Txawm hais tias nws tswj xyuas cov dej ntws los yog ua kom ntseeg tau tias cov tshuaj xa mus rau qhov chaw zoo, li qub feem ntau yog qhov tsis zoo ntawm kev ua haujlwm txhua hnub.
Muaj ntau ntau hom li qub, tab sis qhov sib txawv tseem ceeb ntawm cov cam khwb cia thiab forged li qub. ** Hauv kab lus no, peb yuav tshawb txog qhov sib txawv tseem ceeb ntawm ob hom li qub, saib lawv cov kev tsim kho, kev ua haujlwm ntev, thiab lwm yam.**
Cast Valves
Cam khwb cia li yog tsim los ntawm pouring hlau molten rau hauv pwm, ces cia nws mus solidify thiab txias. Qhov tshwm sim yog lub valve uas yuav siv sij hawm qhov zoo ntawm cov pwm, thiab uas tuaj yeem ua kom ntxaws thiab meej. Cam khwb cia li qub feem ntau yog ua los ntawm cov pa roj carbon steel, stainless hlau, los yog lwm yam alloys.
** Ib qho txiaj ntsig tseem ceeb ntawm cam khwb cia li qub yog tias lawv tuaj yeem tsim ntau qhov ntau, ua rau lawv zoo tagnrho rau kev siv ntau lawm. Lawv kuj feem ntau tsis tshua kim tshaj li forged li qub, txij li cov txheej txheem casting yog yooj yim dua thiab yooj yim dua.**
Txawm li cas los xij, muaj qee qhov downsides rau nrum li qub thiab. Vim tias cov txheej txheem casting, tuaj yeem muaj cov npuas me me lossis lwm yam tsis zoo hauv cov hlau, uas tuaj yeem ua rau lub valve tsis muaj zog. Tsis tas li ntawd, cov qauv nplej ntawm cov hlau hauv lub cam khwb cia tuaj yeem tsis tshua muaj ntom thiab zoo ib yam piv rau lub forged valve, uas tuaj yeem ua rau nws yooj yim rau corrosion lossis lwm yam kev puas tsuaj.
Forged Valves
Forged li qub, ntawm qhov tod tes, yog tsim los ntawm cua sov cov khoom thaiv ntawm cov hlau mus rau qhov kub thiab txias, tom qab ntawd siv lub zog los tsim nws rau hauv daim ntawv xav tau. Tus txheej txheem no, hu ua kub forging, tsim cov qauv sib dhos thiab cov qauv sib dhos hauv cov hlau, uas tuaj yeem ua rau nws muaj zog thiab ntau ruaj dua li cam khwb cia hlau.
** Qhov txiaj ntsig tseem ceeb ntawm forged li qub yog lawv lub zog thiab kav ntev. Vim hais tias cov hlau yog compressed thiab zoo li nyob rau hauv lub siab, nws muaj tsawg defects los yog imperfections uas yuav ua rau nws tsis muaj zog. Tsis tas li ntawd, cov qauv denser tuaj yeem ua rau cov hlau tiv taus corrosion, hnav, thiab lwm yam kev puas tsuaj.**
Txawm li cas los xij, muaj qee qhov downsides rau forged li qub thiab. Vim hais tias ntawm cov txheej txheem forging complex thiab siv sij hawm, lawv feem ntau kim dua li cam khwb cia, thiab tej zaum yuav tsis haum rau cov khoom loj. Tsis tas li ntawd, cov txheej txheem forging tuaj yeem txwv qhov ntau ntawm cov qauv tsim thiab cov duab uas muaj peev xwm ua tau, piv rau cov txheej txheem casting yooj yim dua.
Lwm yam tseem ceeb los xav txog
Thaum xaiv cov cam khwb cia thiab forged li qub, muaj ntau lwm yam uas yuav tsum tau xav txog thiab. Piv txwv li:
- Kev ntsuas siab:Cam khwb cia li qub yuav muaj kev ntsuas qis dua li forged li qub, vim lawv lub peev xwm rau qhov tsis xws luag lossis cov qauv tsis sib xws. Yog tias koj xav tau lub valve uas tuaj yeem tswj cov ntawv thov siab, lub forged valve yuav yog qhov kev xaiv zoo dua.
- Kev ntsuas kub:Ob lub cam khwb cia thiab forged li qub tau ntsuas raws li qhov kub siab tshaj plaws uas lawv tuaj yeem ua haujlwm yam tsis muaj warping, tawg, lossis lwm yam ua tsis tiav. Nco ntsoov xaiv lub valve uas tuaj yeem tiv taus qhov kub ntawm koj daim ntawv thov.
- Kev Kho Kom Zoo:Nyob ntawm daim ntawv thov tshwj xeeb, cam khwb cia lossis forged li qub yuav xav tau ntau hom kev saib xyuas. Piv txwv li, lub cam khwb cia valve tej zaum yuav ua rau corrosion los yog to thaum lub sij hawm, thaum lub forged valve yuav xav tau ib ntus tu los yog lubrication los tswj nws cov kev ua tau zoo.
Xaus
Hauv cov ntsiab lus, muaj qhov sib txawv ntawm cov cam khwb cia thiab forged li qub ntawm kev tsim kho, lub zog, thiab lwm yam. ** Yog tias koj xav tau lub valve uas muaj zog thiab ruaj khov, thiab tuaj yeem ua cov ntawv thov siab, lub forged valve yuav yog qhov kev xaiv zoo dua. Txawm li cas los xij, yog tias koj xav tau lub valve uas tsis tshua kim thiab tuaj yeem tsim tau ntau, lub cam khwb cia valve yuav yog txoj hauv kev mus. Thaum kawg, qhov kev xaiv zoo tshaj plaws yuav nyob ntawm seb qhov yuav tsum tau ua ntawm koj daim ntawv thov, nrog rau koj cov peev nyiaj thiab lwm yam.**
