Koj yuav tsum xyuam xim rau dab tsi thaum txhim kho lub pob hluav taws xob?

Kev saib xyuas ntawm lub pob hluav taws xob muaj xws li kev npaj ua ntej kev teeb tsa, kev teeb tsa ntawm pneumatic pipeline pob li qub, kev tshuaj xyuas tom qab kev teeb tsa ntawm pneumatic pipeline pob li qub, thiab kev saib xyuas ntawm pneumatic pipeline pob li qub.

Lub pob hluav taws xob zoo li xeb thaum siv. Tom qab metallographic qauv tshuaj ntsuam xyuas, dyeing test, heat treatment test, SEM thiab lwm yam kev soj ntsuam, nws tau pom tias qhov tseem ceeb ntawm cov ntaub ntawv corrosion yog carbides raws li ib tug grain ciam teb nyob rau hauv cov khoom precipitate rau chromium-depleted li qub, rooj vag li qub, ntiaj teb li qub, thiab pob li qub, ua rau hluav taws xob Tom qab lub pob valve tau qhib ob peb zaug. Lub zog yuav tsum hloov tau, lub zog yuav tsum yog, thiab lub pneumatic pipeline pob valve yuav tsum ua haujlwm ib txwm. Raws li cov kev xav tau ntawm cov raj xa dej siab, kev sib khi ua haujlwm ntawm qhov sib koom ua ke ntawm lub pneumatic pipeline pob valve thiab cov kav dej flange yuav tsum tau sim tom qab lub siab tso tawm.

Txhawm rau kom ntseeg tau tias lub pneumatic pipeline pob valve tau nruab rau hauv txoj haujlwm coaxial, ob lub flanges ntawm lub raj xa dej yuav tsum tau khaws cia rau tib lub sijhawm thiab paub meej tias cov raj xa dej tuaj yeem nqa tau qhov hnyav ntawm pneumatic pipeline pob valve. Yog tias pom tias lub raj xa dej tsis tuaj yeem nqa qhov hnyav ntawm lub pneumatic pipeline pob valve, muab cov kev txhawb nqa sib xws rau lub raj xa dej ua ntej kev teeb tsa.

Lub sealing gasket yog ntsia nruab nrab ntawm lub pneumatic pipeline pob valve flange thiab cov kav dej flange raws li kev tsim cov raj xa dej. Lub bolts ntawm flange yuav tsum tau nruj nreem symmetrically, successively, thiab tusyees. Yog hais tias lub pneumatic pipeline pob valve siv pneumatic los yog hluav taws xob actuators, ua kom tiav lub installation ntawm cov cua qhov chaw thiab lub hwj chim mov raws li cov lus qhia.

Tsis tas li ntawd, xyuas seb puas muaj impurities, vuam slag, thiab lwm yam hauv cov kav dej, thiab cov kav dej yuav tsum tau ntxuav kom huv.
