Dab tsi yog cam khwb cia hlau yeeb nkab thiab hom cam khwb cia hlau kav?
Cam khwb cia hlau kav, nyob rau hauv layman's cov nqe lus, yog cov yeeb nkab uas ua los ntawm cam khwb cia hlau. Lawv feem ntau siv hauv cov kav dej hauv kev txuag dej, kev tsim kho, thiab kev lag luam.
Vim muaj kev siv zog tsawg thiab ntau txoj kev casting, lawv tuaj yeem muab faib ua cov kav hlau txuas txuas ntxiv thiab centrifugal cam khwb cia hlau kav. Centrifugal cam khwb cia hlau kav txuas ntxiv muab faib ua cov xuab zeb pwm thiab hlau pwm.
Raws li cov ntaub ntawv sib txawv, lawv tau muab faib ua grey cam khwb cia hlau kav thiab cov kav hlau ductile.
Raws li kev sib txawv ntawm qhov sib txawv, lawv tau muab faib ua qhov hloov pauv tau yooj yim, flange interfaces, kev sib txuas ntawm tus kheej, thiab kev sib txuas tsis sib xws.
Ntawm lawv, qhov hloov tau yooj yim interface cam khwb cia hlau yeeb nkab yog kaw nrog lub nplhaib roj hmab. Lub flange interface cam khwb cia hlau yeeb nkab yog tsau nrog ib tug flange thiab kaw nrog ib tug puab roj hmab flange gasket. Rigid interfaces tau pib raug tshem tawm los ntawm kev ua lag luam.
Dab tsi yog hom cam khwb cia hlau kav?
1. Xuab zeb pwm centrifugal cam khwb cia hlau ncaj yeeb nkab: Cov xuab zeb pwm centrifugal cam khwb cia hlau ncaj yeeb nkab yog ua los ntawm grey cam khwb cia hlau, uas yog tsim rau kev thauj mus los ntawm cov kua siab xws li dej thiab roj.
2. Cov kav dej cam khwb cia hlau: Cov dej xa dej cam khwb cia hlau yeeb nkab yog ua los ntawm cov dej cam khwb cia hlau saum toj no 18 thiab yog cam khwb cia los ntawm centrifugal ductile hlau tshuab ntawm kev kub ceev. Cov yeeb nkab hlau yeeb nkab muaj qhov zoo ntawm cov hlau thiab kev ua haujlwm ntawm cov hlau, nrog rau kev tiv thaiv corrosion zoo, zoo ductility, zoo sealing nyhuv thiab yooj yim installation. Nws yog tsuas yog siv rau cov khoom siv dej, roj xa mus thiab cov roj xa mus rau hauv nroog thiab kev lag luam thiab kev lag luam mining. Nws yog thawj qhov kev xaiv rau cov kav dej thiab muaj kev ua haujlwm zoo heev.
3. Dej cam khwb cia hlau yeeb nkab: zoo tib yam cam khwb cia hlau socket yeeb nkab thiab cov yeeb nkab fittings. Saj zawg zog seismic interface ntws cam khwb cia hlau ncaj yeeb nkab, hom cam khwb cia hlau yeeb nkab yog kaw nrog roj hmab nplhaib thiab fastened nrog bolts, thiab muaj zoo saj zawg zog thiab elasticity nyob rau hauv dej siab. Nws tuaj yeem hloov mus rau qhov loj axial hloov chaw thiab sab nraud deformation, thiab haum rau cov kav dej hauv tsev hauv cov tsev siab, tshwj xeeb tshaj yog rau thaj tsam av qeeg. Los ntawm daim ntawv sib txuas, nws tuaj yeem muab faib ua: W-hom hloov tau yooj yim cam khwb cia hlau cov yeeb nkab, B-hom hloov tau yooj yim cam khwb cia hlau cov kav dej, A-hom hloov tau yooj yim cam khwb cia hlau kav dej.
4. Nruam cam khwb cia hlau ncaj yeeb nkab: Nruam cam khwb cia hlau ncaj yeeb nkab yog ib tug tsis tu ncua cam khwb cia hlau cam khwb cia hlau yeeb nkab, haum rau kev thauj mus los ntawm pressurized kua xws li dej thiab roj.
