I. Khoom txhais thiab tus nqi

请替换当前的更多内容Tag nrho peb cov khoom yog formaldehyde dawb ib puag ncig tiv thaiv, muab lub tsev noj qab haus huv tshaj plaws rau koj.

Kev Tiv Thaiv Kev Nyab Xeeb:

Txiav tawm cov dej ntws tawm thaum lub sij hawm tu, tiv thaiv kom tsis txhob muaj kev pheej hmoo thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm tu;

Kev xeem qhov system:

Ua haujlwm raws li kev sib khi kawg hauv kev ntsuas siab, txheeb xyuas qhov kev ua haujlwm siab thiab sealing kev ua haujlwm ntawm cov kav dej;

Flexible Expansion:

Ib ntus kaw cov yeeb nkab chaw nres nkoj, khaws cov interfaces rau yav tom ntej kev nthuav dav.

Piv rau grey cam khwb cia hlau qhov muag tsis pom flanges, ductile hlau, vim lub spherical faib ntawm graphite, tau zoo heev tensile lub zog thiab tej yam toughness, thaum tseem yog tus nqi ntau dua - zoo, ua rau nws nyiam cov khoom siv rau hauv nroog thiab kev siv.

II. Cov Lus Qhia Tseem Ceeb

Kev ntsuas siab:

Cov kev ntsuas siab tseem ceeb tau teev tseg rau txhua tus qauv, nrog rau qee qhov kev qhia tshwj xeeb txhawb siab - kev ntsuas siab.

Qhov Loj Loj:

Npog tus qauv rau qhov loj me, nrog rau qhov loj me yog qhov loj - cov qauv tsim thiab qhov loj me uas yuav tsum tau muaj kev cai ntau lawm.

Khoom siv Standards:

Yuav tsum tau siv cov qhab nia ntawm cov khoom siv hlau, lub rooj sib tham tau teev cov tensile lub zog thiab cov ntsuas elongation.

III. Cov yam ntxwv ntawm cov khoom thiab kev ua tau zoo

Khoom Khoom

Ductile hlau, los ntawm qhov tsis tshua muaj -kev kho mob hauv ntiaj teb magnesium alloy spheroidization, tsim cov microstructure tshwj xeeb, nqa plaub qhov zoo:

Mechanical Properties:

Cov txiaj ntsig zoo zog piv, mus txog qhov siab ntawm - lub zog steel, muaj peev xwm tiv taus qhov kev hloov pauv siab;

Corrosion Resistance:

Lub neej ua haujlwm ntev hauv cov dej phwj hauv nroog vim yog epoxy resin txheej lossis kev kho cov cement hauv ob sab phlu;

Machineability:

Superior casting fluidity piv rau grey cam khwb cia hlau, tso cai rau ib tug -daim molding ntawm complex bolt qhov layouts;

Kev lag luam:

Cov nqi raw khoom qis dua cov hlau tsis muaj steel, thiab tsis muaj cov txheej txheem vuam nyuaj yuav tsum tau ua.

Common Defect Control

Peb qhov teeb meem tseem ceeb los tiv thaiv thaum lub sijhawm tsim khoom

Shrinkage Cavities thiab Porosity

Tswj cov pa roj carbon sib npaug hauv qhov tsim nyog, ua kom ruaj khov ntawm qhov kub thiab txias, thiab siv cov cua txias los pab ua kom muaj zog ntxiv;

Slag suav nrog

nruj me ntsis tswj cov ntsiab lus impurity ntawm molten hlau, nruab slag lim cov ntxaij vab tshaus thiab slag sau hnab, thiab xyuas kom meej casting kub raws li cov qauv;

Graphite Floating

Tswj lub sab sauv txwv ntawm carbon sib npaug, thiab ua kom tiav casting tam sim ntawd tom qab inoculation kho.

IV. Xaiv Phau Ntawv Qhia

Peb xaiv yam

Kev sib txuam siab:

Xaiv cov kev ntsuas siab sib xws rau qis- cov tshuab siab, thiab xaiv qhov ntsuas siab tsim nyog rau kev lag luam siab - cov xwm txheej siab;

Media Compatibility:

Rau cov dej khib nyiab, ua qhov tseem ceeb hauv cov cement hauv ob sab phlu + epoxy txheej txheej; rau cov kua dej tshuaj lom neeg, yuav tsum tau ua kom muaj kev tiv thaiv corrosion{1}};

Kev sib txuas Compatibility:

Paub meej tias lub sealing nto hom thiab bolt qhov tus naj npawb ntawm cov yeeb nkab flange kom ntseeg tau tias sib piv cov qauv kev sib txuas.

V. Kev teeb tsa, Kev Kho, thiab Daim Ntawv Thov

1. Tus txheej txheem kev teeb tsa

● Ntxuav lub flange sealing nto kom tshem tawm cov roj thiab xeb

● Xaiv cov gaskets uas tsim nyog (nitrile roj hmab rau lub tshuab dej, graphite gaskets rau siab -qhov kub thiab txias);

● Tighten bolts tusyees nyob rau hauv ib kab pheeb ces kaum, kom lub torque ua tau raws li cov qauv;

● Ua qhov ntsuas siab tom qab kev teeb tsa; tsis muaj qhov xau thaum lub sij hawm tuav yog txiav txim siab (tsim nyog).

2. Cov Ntsiab Lus Tseem Ceeb

Kev tshuaj xyuas tsis tu ncua:

Tsis tu ncua xyuas bolt torque thiab gasket aging;

Kev tiv thaiv corrosion:

Siv cov tshuaj tiv thaiv- xeb xim rau qhov chaw flange; faus flanges xav tau kev tiv thaiv cathodic;

Kev kho thaum muaj xwm ceev:

Nyob rau hauv cov ntaub ntawv ntawm to, thawj kaw lub upstream valve; depressurize thiab khoob lub raj xa dej ua ntej hloov cov gaskets.

3. Tej thaj chaw thov

Municipal Engineering:Waterworks pipeline davhlau ya nyob twg, dej phwj kho nroj tsuag sedimentation tank qhov hluav taws xob;

Industrial Systems:Chemical cia tank inlet, fais fab nroj tsuag circulating dej pipeline tu thiab cais;

Tshwj xeeb Scenario:Oilfield dej txhaj tshuaj system siab kuaj, ua liaj ua teb irrigation pipeline davhlau ya nyob twg kaw.
