FKM roj nres valve foob CNC sealing nplhaib
Khoom Khoom Zoo
1. Tshuaj stability
FKM (fluororubber) cov khoom muaj tshuaj lom neeg zoo heev. Nyob rau hauv kev lag luam roj, nres li qub yog raug rau ntau yam tshuaj complex, xws li sulfides thiab organic acids nyob rau hauv cov roj crude. FKM sealing rings tuaj yeem tiv thaiv kev yaig ntawm cov tshuaj no. Txawm tias nyob rau hauv ib puag ncig uas muaj siab hydrogen sulfide (xws li 500-1000ppm), yuav tsis muaj kev hloov tshuaj lom neeg pom tseeb, tiv thaiv kev foob tsis ua haujlwm los ntawm tshuaj lom neeg corrosion.
2. Kub kub tsis kam
Nws qhov kub tsis kam yog qhov tseem ceeb thiab tuaj yeem ua haujlwm ib txwm nyob rau hauv qhov kub thiab txias. Nyob rau hauv qhov kub siab txuas ntawm cov txheej txheem roj refining, xws li catalytic cracking units, qhov nruab nrab kub tuaj yeem siab txog li 200 degree. FKM sealing rings tseem tuaj yeem tswj tau zoo elasticity thiab sealing kev ua tau zoo nyob rau hauv qhov kub thiab txias. Nws qhov kub hloov pauv ntawm iav ua rau nws tsis yooj yim softened ntawm qhov kub thiab txias, kom ntseeg tau qhov kev ruaj ntseg sealing ntawm qhov nres valve nyob rau hauv qhov kub thiab txias.
3. Roj kuj
Kev kam rau siab zoo rau roj av thiab nws cov khoom. Txij li cov roj nres valve feem ntau yog siv los tswj cov roj ntws, lub nplhaib sealing yuav tsum tau muab tso rau hauv cov roj nruab nrab ntev. FKM cov khoom yuav tsis o tom qab hu rau cov roj zoo li qee cov roj hmab zoo tib yam, uas ua kom nws qhov kev ruaj ntseg thiab tswj tau qhov zoo sealing nyhuv.
Cov khoom cNC ua cov yam ntxwv
1. Kev ua haujlwm siab
Piv txwv li, sab hauv txoj kab uas hla tuaj yeem ncav cuag ±{{0}}.03mm, thiab sab nraud txoj kab uas hla tuaj yeem ncav cuag ± 0.05mm;
2. Complex shape manufacturing
Muaj peev xwm ntawm kev tsim sealing rings ntawm complex duab. Cov duab uas yuav tsum tau muaj ntawm lub nplhaib sealing ntawm cov roj nres valve txawv nyob ntawm daim ntawv thov tshwj xeeb, uas tej zaum yuav yog O-puab, V-puab lossis lwm yam duab tshwj xeeb. CNC kev ua haujlwm tuaj yeem hloov kho cov cuab yeej txoj hauv kev raws li cov qauv tsim los tsim cov nplhaib sib khi ntawm ntau yam duab kom tau raws li qhov xav tau sib khi ntawm ntau hom nres li qub.
3. Nto zoo optimization
CNC ua tiav tuaj yeem ua tiav qhov zoo. Qhov nto roughness ntawm lub nplhaib sealing tuaj yeem ncav cuag tus qauv siab ntawm Ra0.8 - Ra1.6μm. Qhov saum npoo du txo qhov kev sib txhuam ntawm lub rooj zaum valve thiab lub qia valve, txo qhov kev pheej hmoo ntawm kev hnav, thiab txuas ntxiv lub neej kev pab cuam ntawm lub nplhaib sealing, thaum tseem pab txhim kho lub sealing nyhuv.
| Tsis muaj | Kev siv tus nqi ntau |
| Ntug hardness | 85 ± 3 (Ntu A) |
| Tensile zog | Ntau dua lossis sib npaug rau 10 - 15MPa (nyob ntawm kev tsim thiab txheej txheem) |
| Tear elongation | Ntau dua lossis sib npaug li 150% - 250% |
| Compression teeb (70 degree × 22h) | Tsawg dua lossis sib npaug li 20% - 30% |
| Qhov kub thiab txias | -20 degree - 200 degree (siv mus ntev), mus txog 250 degree rau lub sijhawm luv |
| Roj tsis kam (lub ntim hloov pauv, tom qab immersion hauv cov roj tshwj xeeb) | Tsawg dua lossis sib npaug li 5% - 10% |
| Qhov ntom | Hais txog 1.8 - 20g/cm³ |
Daim ntawv thov Description
Daim ntawv thov hauv roj nres li qub
1. Kev ua haujlwm zoo sealing
Nrog rau cov yam ntxwv zoo ntawm FKM cov ntaub ntawv thiab qhov siab precision ntawm CNC machining, lub nplhaib sealing muab kev ua haujlwm zoo sealing hauv cov roj nres valve. Txawm hais tias nyob rau hauv high-pressure (xws li 10-30MPa) los yog low-pressure oil pipeline systems, nws muaj peev xwm tiv thaiv cov roj to. Nyob rau hauv lub complex pipeline system ntawm offshore roj platforms, nws txhim khu kev qha sealing kev ua tau zoo ua kom muaj kev ruaj ntseg ntawm cov roj extraction thiab kev thauj mus los.
2. Compatibility thiab kev ntseeg tau
Nws muaj kev sib raug zoo nrog cov khoom hlau hauv cov roj nres li qub (xws li cov hlau tsis muaj steel lossis carbon steel valve lub rooj zaum thiab valve stems). Lub sealing kev ua tau zoo yuav tsis cuam tshuam los ntawm cov tshuaj tiv thaiv ntawm cov ntaub ntawv, kom ntseeg tau tag nrho cov kev cia siab thiab stability ntawm lub nres valve. Hauv cov txheej txheem ua haujlwm ntev, qhov zaus ntawm kev kho thiab hloov pauv los ntawm cov teeb meem sealing raug txo, thiab cov nqi kho mob raug txo.
Ntau customized rau roj valve roj hmab sealing kev daws teeb meem, thov xa daim duab los yog kuaj raupeb.
