Dab tsi yog cov kabmob kaw, cov kabmob foob hom

 

Lub npe hu ua sealed bearing yog plua plav pov thawj cov kabmob, kom cov kabmob raug kaw zoo kom cov kabmob du thiab ib puag ncig ua haujlwm, muab kev ua si tag nrho rau kev ua haujlwm ntawm cov kabmob, ua kom lub neej ntev ntawm cov kabmob, thiab muaj lub foob tsim nyog rau cov kabmob dov kom tsis txhob muaj qhov to ntawm tus neeg saib xyuas smoothing thiab cuam tshuam ntawm plua plav, dej vapor lossis lwm yam av. Qhov no yog qhov zoo rau kev tiv thaiv ntawm cov kabmob.

 

Bearing Foob Hom:

Tnws sealing ntaus qauv ntawm dov bearings feem ntau yog muab faib ua cov ntsaws ruaj ruaj thiab cov ntsaws ruaj ruaj tsis sib cuag.

 

Tsis sib cuag sealing ntawm bearings

 

Bearing non-contact sealing yog ib txoj kev sib khi uas tsim kom muaj qhov sib txawv me me ntawm cov ncej thiab lub hau kawg ntawm cov kabmob vaj tse. Hom sealing qauv no tsis hu rau lub ncej, yog li tsis muaj kev sib txhuam thiab hnav, thiab nws yog qhov tsim nyog rau kev sib hloov ceev. Txhawm rau txhim kho cov nyhuv sealing, qhov sib txawv tuaj yeem sau nrog roj. Cov kabmob uas tsis sib cuag cov ntsaws ruaj ruaj feem ntau suav nrog: qhov sib txawv seal, roj zawj foob, labyrinth foob, roj slinger foob, thiab lwm yam.

 

1. Gap sealing

Lub qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.

 

2. Roj groove sealing

 

Cov roj groove foob yog ua tiav nrog cov roj annular ntawm cov ntawv xov xwm ntawm cov kab noj hniav sab hauv ntawm cov kabmob foob kawg, thiab cov roj taw qhia zawj yog radially faib, thiab txhua cov roj annular sib txuas lus los ntawm cov roj qhia groove thiab sib txuas lus nrog cov roj tank. , thiab tus naj npawb ntawm cov roj groove thiab cov roj qhia groove yog txiav txim siab los ntawm qhov loj ntawm lub foob kawg npog.

 

3. Labyrinth sealing

Lub hauv paus ntsiab lus ntawm kev sib khi no yog tsim kom muaj cov dej ntws ntws ntawm lub foob nrog cov dej ntws zoo heev. Raws li txoj cai, qhov sib txawv me me yog tsim los ntawm qhov chaw ruaj khov thiab qhov sib hloov los ua ib qho "labyrinth".

 

4. Roj slinger sealing

 

Hu rau cov ntsaws ruaj ruaj rau bearings

Kev sib cuag sealing yog txoj kev sib khi ntawm qhov kawg lossis daim di ncauj sib txuas ntawm cov roj hmab hluavtaws vulcanized ntawm cov pob txha steel, thiab nws cov sealing kev ua tau zoo yog qhov zoo tshaj qhov tsis sib cuag sealing, tab sis qhov kev sib txhuam loj loj, thiab qhov kub thiab txias yog qhov siab. Qhov chaw sib cuag ntawm lub ncej thiab lub foob yuav tsum tau lubricated, feem ntau yog nrog tib lub roj nplua nyeem raws li cov kabmob. Kev sib cuag cov ntsaws ruaj ruaj feem ntau suav nrog: muaj lub nplhaib sealing, tawv lub tais sealing, sealing nplhaib sealing, skeleton sealing, sealing nplhaib sealing, thiab lwm yam.

 

1. Felt nplhaib sealing

Lub trapezoidal zawj yog qhib rau ntawm cov kabmob npog, thiab cov kev xav zoo ntawm cov duab plaub yog muab tso rau hauv qhov trapezoidal zawj rau kev sib cuag nrog cov ncej, los yog lub caj pas yog nias axially kom lub nplhaib muaj zog compressed thiab tsim radial siab los tuav nws. cov ncej, thiaj li ua tiav lub hom phiaj ntawm sealing.

 

2.Lub tais tawv yog kaw

 

Lub tais ntim cov tawv nqaij (ua los ntawm cov ntaub ntawv xws li roj hmab rub tawm) yog muab tso rau hauv lub hau npog thiab nias ncaj qha rau ntawm ncej. Txhawm rau txhim kho cov nyhuv sealing, lub nplhaib coil caij nplooj ntoos hlav yog nias rau ntawm lub nplhaib sab hauv ntawm lub tais tawv, kom lub nplhaib puab ntawm lub tais tawv muaj nruj dua nrog cov ncej..

 

3. Lub nplhaib sealing yog kaw

Cov ntsaws ruaj ruaj feem ntau yog ua los ntawm tawv, yas los yog roj-resistant roj hmab thiab tuaj yeem ua rau ntau qhov sib txawv raws li qhov xav tau. Lub nplhaib 0-shaped sealing muaj ib lub voj voog ncig, tso siab rau nws tus kheej elastic quab yuam los nias ntawm lub ncej, nrog cov qauv yooj yim thiab yooj yim sib dhos thiab disassembly. J-shaped thiab U-zoo li cov ntsaws ruaj ruaj kuj tseem siv tau, ob qho tib si uas muaj lub ntsej muag zoo li tus qauv.

 

4. Skeleton sealing

 

Txhawm rau txhim kho lub zog tag nrho ntawm tawv lub tais foob, cov hlau hauv ob sab phlu nrog L-shaped cross-section thiab annular shape yog ntsia rau hauv cov roj hmab-resistant roj hmab, kom cov tawv lub tais foob tsis yooj yim rau deform, thiab Lub neej kev pabcuam tau txhim kho nyob rau hauv cov ntaub ntawv ntawm <7m / s, feem ntau ntawm cov centrifugal twj bearing thawv yog tam sim no kaw nrog pob txha.

 

5. Lub nplhaib sealing

Qhov no yog ib hom ntawm lub nplhaib sib khi nrog ib qho notch, nws yog muab tso rau hauv lub nplhaib zawj ntawm lub tes tsho, lub tes tsho tig ua ke nrog cov ncej, thiab lub nplhaib sealing yog nias rau sab hauv lub qhov phab ntsa ntawm qhov chaw nres tsheb los ntawm elasticity. notch yog nias, thiab nws tuaj yeem ua lub luag haujlwm sealing, thiab hom sealing no nyuaj dua.

 

Kev xaiv ntawm bearing seal qauv

 

Thaum xaiv cov qauv kev sib khi, cov ntsiab lus tseem ceeb yuav tsum xav txog yog: roj nplua nyeem, uas yog, txawm tias nws yog roj lossis roj; Linear ceev ntawm sealing qhov chaw; installation yuam kev ntawm lub ncej; Qhov loj thiab tus nqi ntawm qhov chaw installation, thiab lwm yam.
