Kev tsim thiab kev ua haujlwm ntawm cov tshuab foob yog qhov nyuaj, suav nrog ob peb yam tseem ceeb. Lawv yog tsim los ntawm lub ntsej muag foob, elastomers, cov ntsaws ruaj ruaj, thiab cov khoom siv kho vajtse, txhua tus muaj cov yam ntxwv tshwj xeeb thiab lub hom phiaj.

Qhov tseem ceeb ntawm lub tshuab foob muaj xws li:

1. Rotating ntsej muag (Pib Ntiv Nplhaib):Qhov no yog ib feem ntawm lub tshuab foob uas tig nrog lub ncej. Nws feem ntau muaj lub ntsej muag tawv, hnav-tiv taus ua los ntawm cov ntaub ntawv xws li carbon, ceramic, lossis tungsten carbide.
2. Lub ntsej muag nyob ruaj ruaj (lub rooj zaum lossis lub nplhaib thib ob):Lub ntsej muag nyob ruaj ruaj tseem ruaj thiab tsis tig. Nws feem ntau yog ua los ntawm cov khoom siv softer uas ntxiv rau lub ntsej muag tig, tsim kom muaj lub foob sib txuas. Cov ntaub ntawv muaj xws li ceramic, silicon carbide, thiab ntau yam elastomers.
3. Elastomers:Elastomeric Cheebtsam, xws li O-rings thiab gaskets, yog siv los muab ib tug saj zawg zog thiab ruaj ntseg foob ntawm lub tsev nyob ruaj ruaj thiab lub rotating ncej.
4. Secondary Sealing Elements:Cov no suav nrog O-rings thib ob, V-rings, lossis lwm yam khoom sib khi uas pab tiv thaiv cov kab mob sab nraud los ntawm kev nkag mus rau qhov chaw sib khi.
5. Hlau qhov chaw:Ntau yam khoom siv hlau, xws li cov hlau casing lossis cov hlua tsav, tuav lub tshuab foob ua ke thiab ruaj ntseg rau cov khoom siv.

Mechanical foob ntsej muag

• Rotating foob lub ntsej muag: Lub nplhaib tseem ceeb, lossis lub ntsej muag lub ntsej muag tig, txav mus rau hauv tandem nrog lub tshuab tig, feem ntau yog cov ncej. Lub nplhaib no feem ntau yog tsim los ntawm cov khoom siv tawv, ruaj khov xws li silicon carbide lossis tungsten carbide. Kev tsim ntawm lub nplhaib tseem ceeb kom ntseeg tau tias nws tuaj yeem txhawb nqa lub zog ua haujlwm thiab kev sib txhuam tsim tawm thaum lub tshuab ua haujlwm tsis muaj deformation lossis hnav ntau dhau.

• Lub ntsej muag ruaj ruaj: Hauv qhov sib piv rau lub nplhaib tseem ceeb, lub nplhaib mating tseem nyob ruaj khov. Nws yog tsim los tsim ib qho kev sib khi nrog lub nplhaib tseem ceeb. Txawm hais tias nyob ruaj ruaj, nws tau tsim kho kom haum rau kev txav ntawm lub nplhaib tseem ceeb thaum tuav lub foob muaj zog. Lub nplhaib mating feem ntau yog tsim los ntawm cov khoom siv xws li carbon, ceramic, lossis silicon carbide.

Elastomers (O-rings lossis bellows)

Cov ntsiab lus no, feem ntau yog O-rings lossis bellows, ua haujlwm los muab qhov tsim nyog elasticity los tuav lub foob ntawm lub tshuab foob sib dhos thiab lub tshuab lub tog raj lossis vaj tsev. Lawv ua kom haum me ntsis ntawm cov ncej misalignment thiab vibrations yam tsis muaj kev cuam tshuam lub foob kev ncaj ncees. Qhov kev xaiv ntawm cov khoom siv elastomer nyob ntawm ntau yam, suav nrog qhov kub thiab txias, siab, thiab qhov xwm txheej ntawm cov kua dej raug kaw.

Secondary Seals

Secondary seals yog cov khoom siv uas muab qhov chaw sib khi zoo li qub nyob rau hauv lub tshuab foob sib dhos. Lawv txhim kho lub foob kev ua tau zoo thiab kev ntseeg siab, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej zoo.

Kho vajtse

• Springs: Springs muab qhov tsim nyog thauj khoom rau lub ntsej muag foob, ua kom muaj kev sib cuag tsis tu ncua ntawm lawv txawm tias muaj kev ua haujlwm sib txawv. Qhov kev tiv tauj tas li no ua kom muaj kev ruaj ntseg thiab ua haujlwm tau zoo thoob plaws lub tshuab ua haujlwm.

• Cov tuav tseg: Retainers tuav ntau yam khoom ntawm lub foob ua ke. Lawv tuav qhov kev sib raug zoo thiab txoj hauj lwm ntawm lub foob sib dhos, kom ntseeg tau tias kev ua haujlwm zoo.

• Gland daim hlau: Gland daim hlau yog siv los mount lub foob rau lub tshuab. Lawv txhawb nqa lub foob sib dhos, ua kom nws ruaj ntseg.

• Teem screws: Teem screws yog me me, threaded Cheebtsam siv rau kev ruaj ntseg cov neeg kho tshuab foob los ua ke rau lub ncej. Lawv xyuas kom meej tias lub foob tuav nws txoj haujlwm thaum lub sijhawm ua haujlwm, tiv thaiv qhov muaj peev xwm hloov chaw uas tuaj yeem cuam tshuam lub foob kev ua haujlwm.

 

 

 

 

Hauv kev xaus

Txhua feem ntawm lub tshuab foob ua lub luag haujlwm tseem ceeb hauv kev sib khi zoo ntawm cov tshuab ua haujlwm. Los ntawm kev nkag siab txog kev ua haujlwm thiab qhov tseem ceeb ntawm cov khoom no, ib tus tuaj yeem txaus siab rau qhov nyuaj thiab qhov tseeb uas yuav tsum tau ua hauv kev tsim thiab tswj xyuas cov khoom siv kho tshuab zoo.
