Tungsten Carbide Pob Lub Rooj Pob Valve
Kev piav qhia
-
Cov yam ntxwv ntawm cov khoom siv tungsten carbide
- High hardness:
- Lub hardness ntawm tungsten carbide yog siab heev, thib ob tsuas yog pob zeb diamond, uas muab nws zoo heev hnav tsis kam. Thaum lub sijhawm siv lub valve, nws tuaj yeem tiv taus qhov yaig thiab hnav ntawm qhov nruab nrab, ncua kev pabcuam lub neej ntawm lub valve.
- Corrosion kuj:
- Tungsten carbide muaj cov khoom siv tshuaj ruaj khov thiab tsis yooj yim rau kev tawm tsam nrog corrosive media xws li kua qaub, alkali, ntsev, thiab lwm yam. Nws tuaj yeem siv tau ntev hauv qhov chaw hnyav corrosive yam tsis muaj kev puas tsuaj.
- Kub kub kuj:
- Lub melting point ntawm tungsten carbide yog siab li 2870 ℃ (tseem hu ua 3410 ℃), uas muaj qhov kub thiab txias tsis kam thiab tuaj yeem tswj kev ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias.
- Siab zog:
- Tungsten carbide muaj lub zog siab thiab tuaj yeem tiv taus lub zog tseem ceeb thiab cuam tshuam, ua kom ruaj khov ntawm cov li qub hauv kev ua haujlwm hnyav.

Cov yam ntxwv ntawm tungsten carbide pob lub rooj pob valve
- Kev ua tau zoo sealing zoo:
- Lub tungsten carbide pob valve siv tungsten carbide raws li cov khoom siv sib khi, uas muaj qhov hnyav heev thiab hnav tsis kam, thiab tuaj yeem ua tiav xoom xaim sealing nyhuv. Lub caij no, qhov kev tiv thaiv corrosion ntawm tungsten carbide kuj ua kom ruaj khov kev ua haujlwm ntawm lub valve hauv corrosive media.
- Ntev lifespan:
- Vim lub siab tawv thiab hnav tsis kam ntawm tungsten carbide, lub neej kev pab cuam ntawm tungsten carbide pob li qub tau txuas ntxiv, txo qhov zaus ntawm kev hloov pauv thiab cov nqi kho.
- Kev siv dav dav:
- Tungsten carbide pob valve yog tsim rau ntau yam kev ua haujlwm hnyav, xws li kub kub, siab kub, muaj zog corrosiveness, slurry thiab hmoov uas muaj cov khoom siv, thiab lwm yam. Qhov no ua rau tungsten carbide pob li qub muaj kev thov dav dav hauv thaj chaw xws li tshuaj lom neeg, roj av, metallurgy, thiab lub zog.
-
Qhov zoo ntawm tungsten carbide pob lub rooj pob valve
- Txhim kho ntau lawm efficiency:
- Kev ua haujlwm siab thiab kev ua neej ntev ntawm tungsten carbide pob li qub kom ruaj khov ntawm cov kab ntau lawm, txo qis lub sijhawm los ntawm qhov tsis ua haujlwm valve thiab yog li txhim kho kev tsim khoom.
- Txo cov nqi kho mob:
- Vim lub neej ua haujlwm ntev ntawm tungsten carbide pob li qub, qhov zaus ntawm kev hloov lub valve thiab kev saib xyuas haujlwm raug txo, yog li txo cov nqi kho.
- Txhim kho kev nyab xeeb:
- Kev sib khi zoo heev thiab kev ruaj ntseg ntawm tungsten carbide pob li qub kom ntseeg tau tias qhov nruab nrab yuav tsis xau, zam kev nyab xeeb thiab kev ua qias tuaj ib puag ncig los ntawm kev xau.
