Dej Meter Iav PM Sintered Part
Qhov zoo ntawm cov kais dej hauv tsev tau txhim kho tau zoo nyob rau xyoo tas los no, tab sis qee cov kav dej tsis pom zoo tseem muaj impurities xws li xeb, hemp, hlau filings, thiab pob zeb. Cov impurities thaum kawg tuaj txog ntawm qhov nkag ntawm lub ntsuas dej nrog rau cov dej ntws. Txhawm rau tiv thaiv impurities los ntawm kev nkag mus rau hauv lub ntsuas dej core thiab ua rau lub ntsuas dej tsis ua haujlwm, lub lim dej tau teeb tsa rau ntawm qhov kawg ntawm lub ntsuas dej.

Lub iav ntawm lub ntsuas dej muaj lub luag haujlwm ntawm kev txais lub zog ntawm lub impeller tig thiab xa cov quab yuam mus rau cov khoom txuas ntxiv. Muaj kev sib txuas zoo ntawm ntau yam khoom, yog li lub iav yuav tsum ua kom muaj zog siab.
Lub zog ntawm lub ntsuas dej yog ua los ntawm cov khoom siv nrog super hardness, tiv thaiv xeb, thiab tsis yooj yim rau cov hniav. Cov 1-3 iav yog ua los ntawm cov hlau tsis muaj zog, thiab cov khoom seem ntawm cov iav thiab cov iav tuaj yeem ua los ntawm cov khoom siv hluav taws xob tsis zoo.
Cov qauv dej ntsuas dej - lub luag haujlwm ntawm txhua yam
1. Saib rooj plaub, npog nruab nrab, saib iav
Cov ntaub ntawv saib, lub hau nruab nrab, lub iav saib thiab lub sealing gasket ua ke ua lub cev sib khi, kom cov dej ntsuas hauv lub moos yuav tsis tawm ntawm lub moos. Raws li lub teb chaws tus qauv, lub ntsuas dej yuav tsum tuaj yeem tiv taus qhov ntsuas siab ntawm 1.6MPa rau 15min thiab 2.0MPa rau 1min. Yog li ntawd, cov ntaub ntawv saib, npog nruab nrab thiab saib iav yuav tsum ua tau raws li qhov xav tau saum toj no.
Cov ntaub ntawv feem ntau yog grey cam khwb cia hlau (HT l50, saib GB 9436-1988) lossis cam khwb cia tooj dag (ZcuZn40Pb2, saib GB ll76-1987). Cov khoom ntawm lub hau nruab nrab yog feem ntau nrum txhuas tooj dag (ZcuZn40Pb2, saib GB 1176-1987). Lub iav saib yuav tsum yog iav tempered raws li JB/T 8480-1996.
2. Cov chaw ntsuas
Lub metering mechanism feem ntau yog tsim los ntawm lub thawv iav, lub thawv impeller, ib qho impeller, lub hau sab saum toj, thiab cov phaj hloov. Lub metering mechanism yog "lub plawv" ntawm lub ntsuas dej, uas ua lub luag haujlwm tseem ceeb hauv kev ntsuas kev ua tau zoo thiab ua haujlwm ntev ntawm lub ntsuas dej.
3. suav tshuab
Cov txheej txheem suav feem ntau yog hu ua lub txee, thiab cov ntaub ntawv ntau yog pointer type, lo lus log hom thiab kev sib xyaw ntawm pointer lo lus log hom.
4. lim dej
Qhov zoo ntawm cov kais dej hauv tsev tau txhim kho tau zoo nyob rau xyoo tas los no, tab sis qee cov kav dej tsis pom zoo tseem muaj impurities xws li xeb, hemp, hlau filings, thiab pob zeb. Cov impurities thaum kawg tuaj txog ntawm qhov nkag ntawm lub ntsuas dej nrog rau cov dej ntws. Txhawm rau tiv thaiv impurities los ntawm kev nkag mus rau hauv lub ntsuas dej core thiab ua rau lub ntsuas dej tsis ua haujlwm, lub lim dej tau teeb tsa rau ntawm qhov kawg ntawm lub ntsuas dej.
