V-Seals yog dab tsi?
V-Seals, raws li nws lub npe piav qhia, muaj "V"-zoo li tus ntoo khaub lig-section.
Nws muaj cov yam ntxwv ntawm kev ua haujlwm tsis zoo, kev ua haujlwm du, kev ua haujlwm siab, kev co thiab kev cuam tshuam, thiab tuaj yeem ua tau raws li cov yam ntxwv ntawm cov xov xwm sib txawv thiab siv cov xwm txheej, thiab tuaj yeem ntxiv ntau lub nplhaib nruab nrab los siv ua ke kom tau qhov zoo tshaj plaws. sealing nyhuv los ntawm kev kho lub compression quab yuam. Txawm li cas los xij, nws cov kev sib txhuam tsis sib haum yog loj, thiab nws cov qauv yog complex. Nws yuav tsum tau nruab nrog lub siab thiab txhawb nqa rings; sealing kev ua tau zoo yuav tsis ruaj khov. Nws yog feem ntau siv rau dynamic sealing ntawm reciprocating pistons los yog piston rods thiab kuj yog ib feem siv rau rotating, rotating los yog static ua hauj lwm tej yam kev mob.
Raws li tau hais ua ntej, V-Seals muaj peb ntu: nruab nrab V-ntiv nplhaib, lub nplhaib txhawb nqa sab sauv thiab qis thiab lub nplhaib compression. V-ring tuaj yeem yog 3 daim, 5 daim, 7 daim, thiab lwm yam .... raws li koj xav tau.
Vim li cas thiaj siv V-Seals hauv cov khoom siv tshuab?
1. V-seals yog dav siv di ncauj ntsaws ruaj ruaj nrog lub sij hawm ntev kev tsub zuj zuj. Piv nrog cov di ncauj ntsaws ruaj ruaj, cov yam ntxwv tseem ceeb ntawm V-shaped seals yog raws li hauv qab no:
2. Raws li kev ua haujlwm, lub siab yuav tsum tau nqa thiab tus naj npawb ntawm cov khoom yuav tsum tau ua ke tuaj yeem xaiv tau raws li qhov tseeb siab. Lub sealing kev ua tau zoo yuav nce ntxiv nrog rau qhov nce ntawm tus naj npawb ntawm cov nplhaib nruab nrab, tab sis nws yuav tsum tau muab sau tseg tias kev sib raug zoo ntawm kev sib khi ua tau zoo thiab tus naj npawb ntawm cov nplhaib nruab nrab tsis yog linear; thaum lub nplhaib nruab nrab yog nce, qhov kev sib txhuam kuj tseem yuav nce ntxiv.
3. Nws muaj lub zog muaj zog dynamic foob nrog lub peev xwm thauj khoom siab thiab muaj peev xwm tiv thaiv tau zoo heev.
4. Yog tias cov dej xau yog tshwm sim los ntawm deformation lossis hnav ntawm lub nplhaib sealing thaum lub sijhawm ua haujlwm, nws tuaj yeem hloov kho thiab tom qab ntawd nruj nreem los ntawm clamping mechanism kom lub di ncauj lub kaum sab xis, yog li txhim kho cov nyhuv sealing. Lub sealing kev ua tau zoo ntawm pawg V yog txhim khu kev qha, thiab kev pab cuam lub neej ntev.
5. Lub nplhaib nruab nrab tuaj yeem hloov kho kom nce lossis txo raws li kev siv tiag tiag, thiab cov cuab yeej siv tau yooj yim, uas tsim nyog rau kev hloov lub nplhaib sib khi hauv qhov chaw nyuaj.
6. Nws tuaj yeem siv nyob rau hauv qhov tsis tshua muaj siab (5MPa) thiab qis ceev (3m / min) kev sib hloov.
7. Nws muaj kev ua haujlwm zoo los tiv thaiv extrusion nyob rau hauv high-pressure los yog tsis tshua muaj siab.
Lub npe ntawm lub nplhaib V-seal yog tib yam li ntawm O-ring. Vim tias nws qhov hlais zoo ib yam li lub nplhaib V-seal, nws hu ua V-seal nplhaib. V-seal nplhaib yog ib hom di ncauj foob nplhaib.
Lub nplhaib V-seal feem ntau muaj peb ntu: lub nplhaib txhawb nqa, lub nplhaib foob, thiab lub nplhaib siab. Hauv qee qhov chaw ua haujlwm, tus qauv V-foob lub nplhaib lub kaum sab xis yog 90 degrees, uas yog 60 degrees. Lub nplhaib txhawb nqa yog ib qho tseem ceeb ntawm kev txhawb nqa lub nplhaib V-seal. Nws qhov hlais yog tuab thiab muaj zog, qhov loj yog qhov tseeb, thiab lub kaum sab xis yog tib yam li V-seal nplhaib (90) lossis loj dua me ntsis kom nws tuaj yeem tso tau ruaj khov.
