Rotary Union yog dab tsi thiab nws tuaj yeem raug kaw zoo li cas?
Ib qho kev sib koom ua ke yog ib qho txuas uas siv los hloov cov kua dej hauv cov khoom siv tig. Nws tso cai rau cov kua xa tawm los ntawm cov yeeb nkab uas nyob ruaj ruaj los yog cov kab ke mus rau qhov kev sib hloov, xws li lub voj voog tig thaum tuav lub foob kom tsis txhob xau.
Cov hauv qab no yog ib qho kev qhia txog cov pob qij txha thiab lawv cov sealing zoo:
Cov yam ntxwv ntawm kev sib koom ua ke muaj xws li:
- Housing: Lub vaj tsev yog cov txheej txheem sab nraud ntawm kev sib koom ua ke thiab siv los kho thiab txhawb cov khoom siv sab hauv.
- Rotating ncej: Lub rotating ncej yog ib feem uas txuas cov rotating sib koom ua ke mus rau lub rotating tivthaiv (xws li lub rotor los yog nruas). Nws tso cai rau kev hloov pauv thiab hloov pauv ntawm cov kua dej tawm.
- Sealing ntaus ntawv: Lub sealing ntaus ntawv yog ib qho tseem ceeb ntawm kev sib koom ua ke thiab yog siv los xyuas kom meej lub sealing kev ua tau zoo ntawm cov kua. Nws feem ntau muaj cov khoom sib khi xws li cov nplhaib sib khi, cov hlua khi, lossis cov nplhaib sib khi. Rotary pob qij txha yog dav siv nyob rau hauv ntau yam kev siv. Nov yog qee qhov chaw thov siv:
- Rotating Machinery: Cov pob qij txha teb feem ntau yog siv rau hauv kev sib hloov tshuab xws li rotating shafts, rotors, nruas, cua turbines, thiab lwm yam. Lawv yog siv los hloov cov kua xov xwm (xws li roj lubricating, coolant, hydraulic roj, thiab lwm yam) los yog gaseous media ( xws li compressed cua, roj, thiab lwm yam).
Qhov twg siv cov pob qij txha rotary?
- Kev Siv Tshuaj: Hauv cov txheej txheem tshuaj, cov pob qij txha yog siv los thauj cov tshuaj, cov kuab tshuaj, cov pa roj, thiab lwm yam kua dej tawm. Lawv muab kev sib khi thiab cov kua dej hloov pauv hauv cov khoom siv sib hloov xws li cov agitators, spin dryers, centrifuges, thiab lwm yam.
- Kev Lag Luam Roj thiab Roj: Cov pob qij txha teb ua lub luag haujlwm tseem ceeb hauv kev lag luam roj thiab roj. Lawv yog siv rau hauv cov khoom siv roj zoo drilling, cov khoom siv roj av, cov twj tso kua mis, lub tshuab tig, thiab lwm yam.
- Cov Khoom Siv Kho Mob: Cov pob qij txha teb ua lub luag haujlwm tseem ceeb hauv cov khoom siv kho mob. Piv txwv li, lawv yog siv nyob rau hauv rotating qhov chaw nyob rau hauv cov kev kho mob cov cuab yeej (xws li CT scanners, MRI machines) xa mus rau lub hwj chim, teeb liab thiab txias xov xwm.
- Kev lag luam textile: Hauv kev lag luam textile, cov pob qij txha yog siv rau hauv cov khoom siv xws li spinning machine, looms, thiab textile machinery to transfer textile liquids (xws li dyes, auxiliaries, and detergents) thiab gases.
- Kev lag luam khoom noj khoom haus thiab dej haus: cov pob qij txha yog siv rau hauv kev lag luam khoom noj thiab dej haus los thauj cov kua dej xws li cov khoom xyaw zaub mov, khoom noj khoom haus additives, syrups, dej haus thiab kua condiments.
Kev xaiv cov khoom hauv Rotary Seals
Muaj ntau yam uas yuav tsum tau xav txog thaum xaiv cov khoom siv rau lub foob rotary. Kev xaiv cov khoom nyob ntawm ntau yam, nrog rau kev ua haujlwm, kev sib khi xov xwm, kub, siab thiab ceev. Nov yog qee cov khoom siv feem ntau siv rau cov ntsaws ruaj ruaj:
- Nitrile Butadiene Roj Hmab (NBR): Nws muaj qhov ua tau zoo ntawm qhov kub thiab txias thiab muaj txiaj ntsig zoo. Txawm li cas los xij, nws yuav tsis haum rau cov ntawv thov uas muaj qhov kub thiab txias lossis raug rau cov tshuaj lom neeg.
- Fluoroelastomer (FKM): Muaj peev xwm tiv taus cov kua dej ntau thiab feem ntau siv rau hauv cov ntawv siv hnyav uas yuav tsum tau ua rau cov tshuaj corrosive thiab kub kub.
- Polytetrafluoroethylene (PTFE): Feem ntau siv hauv cov ntsaws ruaj ruaj nrog rau lwm cov ntaub ntawv xws li elastomers lossis hlau springs los txhim kho kev sib khi.
- Polyurethane (PU): Muaj peev xwm ua tau ntau yam kua dej, suav nrog cov roj hydraulic, thiab feem ntau siv hauv cov tshuab hydraulic.
- Silicone (VMQ): Tsim nyog rau kev sib khi daim ntawv thov uas muaj qhov kub thiab txias, xws li qhov chaw qis lossis kub kub. Txawm li cas los xij, silicone yuav tsis sib haum nrog qee yam tshuaj.
| Fluorocarbon FKM | Chemours - Viton ™, Dyneon - Dyneon Fluoroelastomer Temp. Ntau yam: -26 ºC rau +204 ºC -15 ºF rau +400 ºF Nqe lus piav qhia: Fluorocarbon yog cov roj kub resistant elastomer uas muaj peev xwm muab ntau yam tshuaj lom neeg sib xws. Muaj ntau ntau yam sib txawv fluorocarbon tebchaw muaj. Lub hauv paus ntawm cov sib txuas sib txawv yog kev koom ua ke ntawm fluorine rau hauv cov saw hlau polymer. Thaum koj ua kom cov fluorine concentration nyob rau hauv lub polymer, qhov ntau dua cov tshuaj tiv thaiv ntawm cov compound. Fluorocarbons Ameslikas tsim los ntawm dipolymer ntawm hexafluoropropylene (HFP) thiab vinylidene fluoride (VDF). Fluorocarbons suav nrog Viton ™ A, B, F thiab cov tsev neeg tshwj xeeb los ntawm Chemours. Haum nrog: Mineral roj thiab roj, HFD, silicone roj thiab roj, zaub roj thiab roj, aliphatic thiab aromatic hydrocarbons, chlorinated hydrocarbons, roj av, ozone, huab cua, kev laus Tsis haum nrog: Glycol-based brake fluids, chav thiab dej kub siab tshaj 100 ºC, Skydrol, polar solvents, ammonia, methanol, amines, alkalis, organic acids |
- Ethylene propylene diene monomer (EPDM): EPDM cov ntsaws ruaj ruaj paub txog lawv cov kev tiv thaiv zoo heev rau huab cua, ozone, thiab kev laus. Lawv ua tau zoo nyob rau hauv dej thiab chav siv thiab tuaj yeem ua tau qee yam tshuaj. Txawm li cas los xij, lawv yuav tsis haum rau kev siv roj thiab hydrocarbons.
