Tus txheej txheem xeem API 607 yog dab tsi?
API 607 yog cov qauv ntsuas hluav taws kub rau kev lag luam li qub luam tawm los ntawm American Petroleum Institute. Nws ua kom ntseeg tau tias cov li qub tuav lawv txoj kev sib khi thiab kev ua haujlwm ruaj khov thaum muaj hluav taws kub. Cov txheej txheem no siv tau rau txhua hom hlau li qub thiab yuav tsum tau kuaj cov li qub hauv qhov siab - qhov kub thiab txias ib puag ncig rau qee lub sijhawm los tshuaj xyuas qhov hluav taws kub ntawm lub valve cov qauv thiab cov khoom siv.
Kev ntsuas hluav taws kub rau kev lag luam li qub suav nrog cov khoom tseem ceeb hauv qab no:
1. Kev ntsuas nplaim hluav taws xob: Lub valve raug rau cov nplaim taws rau 15 feeb lossis ntev dua, raws li lub sijhawm teev tseg.
2. High-kub tuav theem: Tom qab qhov ntsuas hluav taws xob, lub valve tau khaws cia rau hauv qhov chaw siab - qhov kub thiab txias los ntsuas nws qhov kev sib khi thiab seb nws cov qauv puas puas.
3. Kev ntsuas siab sealing: Nyob rau hauv tib lub siab zoo li ua ntej combustion, lub valve raug kuaj xyuas seb nws puas tuaj yeem tuav lub foob thiab tiv thaiv kev tawm mus.
4. Valve mechanical operation check: Tom qab qhov kev ntsuam xyuas, lub valve qhib thiab kaw muaj nuj nqi yog xyuas kom ntseeg tau tias nws cov kev ua tau zoo tsis cuam tshuam.
5. Hlawv -off thiab deformation ntsuas: Lub cev valve, qia valve, ntsaws ruaj ruaj, thiab lwm yam khoom raug tshuaj xyuas kom paub meej tias lawv cov hluav taws kub ua haujlwm.
Cov khoom ntsuas saum toj no ua kom ntseeg tau tias lub valve tsis yog tsuas yog muaj sia nyob hauv qhov chaw hluav taws kub tab sis tseem ua haujlwm txuas ntxiv, uas yog qhov tseem ceeb heev rau kev nyab xeeb ntawm kev lag luam.
Kev soj ntsuam ntawm cov khoom Specifications thiab cov ntsiab lus ntawm kev xeem nyob rau hauv kev ntsuam xyuas hluav taws kub
Raws li API 607-2022 tus qauv, cov kev sim muaj li qub feem ntau npog ntau yam hlau ua rooj vag li qub, lub ntiaj teb li qub, pob li qub, thiab lwm yam, nrog rau qhov ntau thiab tsawg ntawm 2 ntiv mus rau 24 ntiv tes.
Tus qauv muaj cov kev xav tau meej rau cov qauv ntawm cov li qub, qhov hluav taws kub tsis kam ntawm cov khoom sib khi, thiab cov cua kub tsis kam ntawm cov khoom sib txuas. Cov ntsiab lus kuaj suav nrog, tab sis tsis txwv rau:
1. Valve lub cev cov ntaub ntawv tsom xam: Kev ntsuas kev ua tau zoo yog ua los ntawm cov khoom siv hauv lub cev xws li carbon steel, stainless hlau, thiab hlau alloy kom paub meej tias lawv cov khoom siv kho tshuab thiab cov yam ntxwv thermal expansion nyob rau hauv siab - kub.
2. Kev tiv thaiv hluav taws kub ntawm cov khoom sib khi: Feem ntau siv cov khoom sib khi xws li hloov tau yooj yim graphite, ceramic fiber, thiab inorganic fiber yuav tsum dhau qhov siab - kub combustion thiab tshuaj lom neeg stability tests.
3. Valve qia thiab cov thawv ntim khoom sib dhos kuaj: Lub thermal expansion kuj tsim ntawm lub valve qia thiab cov nyhuv sealing ntawm lub thawv ntim khoom yog cov ntsiab lus tseem ceeb ntawm lub valve qhov hluav taws kub ua haujlwm.
4. Kev ntsuas hluav taws xob tag nrho thiab kev sib khi: Lub valve seal kev ncaj ncees yog kuaj los ntawm kev raug ncaj qha mus rau qhov kub siab - nplaim taws kub hnyiab thiab tsis tu ncua kom tiv thaiv kom tsis txhob tawg thaum lub sij hawm combustion.
Cov kev ntsuam xyuas no tsis tsuas yog ntsuas lub valve qhov hluav taws kub ua haujlwm, tab sis kuj tseem cuam tshuam ncaj qha rau lub valve qhov kev ntseeg siab ntawm cov txiaj ntsig hauv kev ua haujlwm hnyav, tshwj xeeb tshaj yog kev ntseeg siab ntawm cov ntaub ntawv thiab cov qauv.
