Cov roj hmab gaskets thiab cov ntsaws ruaj ruaj yog ob feem ntau siv cov khoom pov thawj, ob qho tib si yog ua los ntawm cov ntaub ntawv hloov tau yooj yim thiab siv los sau qhov chaw nruab nrab ntawm ob qhov chaw thiab nres cov kua los yog roj. Txawm li cas los xij, roj hmab gaskets thiab sealing rings tsis zoo ib yam, lawv muaj cov duab sib txawv, cov qauv thiab kev siv.
Cov roj hmab gasket yog dab tsi?
Cov roj hmab gasket yog ib daim ntawv los yog cov ntawv zoo li cov roj hmab uas feem ntau yog siv rau hauv cov ntawv thov zoo li qub, xws li ntawm kev sib txuas, flanges, thiab lwm yam mating nto, los tiv thaiv kev xau. Nyob ntawm cov khoom siv thiab daim ntawv thov, cov roj hmab gaskets tuaj yeem tsim tau siv ntau hom kev siv xws li:
- roj hmab extrusion
- kub vulcanization thiab txias bonding
- Compression, txhaj tshuaj thiab hloov molding
- Precision txiav
- Kev cai tuag txiav
- Dej dav hlau txiav
Roj hmab gaskets yog dav siv nyob rau hauv ntau yam kev lag luam thiab teb xws li roj thiab roj, kev tsim thiab kev lag luam, ntawv ua, khoom siv ua liaj ua teb, thiab lwm yam. Kev hloov cov roj hmab gaskets uas hnav los yog puas lawm feem ntau kuj yooj yim. Nws yog feem ntau pom zoo kom hloov cov roj hmab gaskets thaum cov cuab yeej disassembled thiab reassembled.
Lub nplhaib sealing yog dab tsi?
Seal rings yog ib hom dav dav, nrog rau lub valve qia ntsaws ruaj ruaj, rotary seals, mechanical seals, shaft seals, radial seals, thiab valve qia seals, thiab lwm yam. Tsis zoo li cov roj hmab gaskets, cov ntsaws ruaj ruaj feem ntau yog siv nyob rau hauv ib puag ncig dynamic xws li lub cev muaj zog, cav, twj thiab rotating shafts. Cov ntsaws ruaj ruaj feem ntau muaj lub nplhaib hlau sab nraud thiab cov roj hmab sab hauv uas yog kaum ntawm lub kaum sab xis los tsim daim di ncauj sealing. Lub kaum sab xis no pab tiv thaiv kom tsis txhob xau hauv kev siv dynamic.
Cov ntsaws ruaj ruaj feem ntau yog siv los tiv thaiv kev xau ntawm ob qhov chaw txav mus los thiab kom cov khoom tsis zoo thiab cov kab mob nkag mus rau hauv lub cev. Hloov lub foob puas lossis tawg tuaj yeem ua rau nyuaj. Tsis tsuas yog yuav tsum tau hloov cov ntsaws ruaj ruaj, tab sis tag nrho lub rooj sib txoos yuav tsum tau muab tshem tawm los hloov cov ntsaws ruaj ruaj.
Cov khoom siv rau roj hmab gaskets thiab seals
Roj hmab gaskets thiab cov ntsaws ruaj ruaj tuaj yeem tsim los ntawm ntau yam khoom siv, nyob ntawm lawv daim ntawv thov thiab ib puag ncig. Cov khoom siv dav siv los ua cov roj hmab gaskets thiab cov ntsaws ruaj ruaj muaj xws li:
- Nitrile roj hmab
- Neoprene
- EPDM
- Butyl roj hmab
- Acrylonitrile butadiene roj hmab
- Silicone Roj Hmab
- Polyurethane
- fluororubber
Tag nrho cov ntaub ntawv no tuaj yeem tsim thiab kho raws li qhov xav tau ntawm cov ntawv thov tshwj xeeb. Rau daim ntawv thov uas yuav tsum tau compressible roj hmab gaskets los yog ntsaws ruaj ruaj, kho fibers, cork, graphite, PTFE los yog lwm yam ntaub ntawv compressible yuav siv tau. Kev xaiv cov khoom raug yog nyob ntawm cov lus qhia ntawm cov kws tsim khoom.
Dab tsi yog qhov txawv ntawm cov roj hmab gaskets thiab cov ntsaws ruaj ruaj?
Qhov sib txawv ntawm cov roj hmab gaskets thiab sealing rings tsis pom tseeb, lawv yog ob qho tib si ntawm cov khoom pov thawj. Ntau qhov chaw hauv online yuav qhia rau koj tias qhov sib txawv ntawm cov roj hmab gaskets thiab cov ntsaws ruaj ruaj yog cov roj hmab gaskets siv rau hauv cov khoom zoo li qub thaum cov ntsaws ruaj ruaj yog siv rau hauv cov ntawv thov ntau zog. Txawm li cas los xij, peb ntseeg tias qhov no tsis yog txoj cai kiag li, thiab cov ntsaws ruaj ruaj kuj tuaj yeem siv los txuas cov khoom nyob ruaj ruaj. Yog tias ob qho tib si ua los ntawm cov khoom siv tib yam thiab siv rau tib daim ntawv thov, qhov sib txawv tiag tiag yog dab tsi?
Txoj kev yooj yim tshaj plaws los piav txog qhov sib txawv ntawm cov roj hmab gaskets thiab cov ntsaws ruaj ruaj yog cov ntsaws ruaj ruaj yog ib pawg dav uas suav nrog ntau yam khoom sib txawv. Cov roj hmab gasket tsuas yog ib daim ntawv tshwj xeeb ntawm lub foob. Thaum nws los txog rau kev yuav khoom, qhov sib txawv loj tshaj plaws ntawm cov roj hmab gaskets thiab cov ntsaws ruaj ruaj tsuas yog qhov chaw tsim khoom npe lawv. Yog tias cov roj hmab square hu ua roj hmab gasket ntawm ib lub vev xaib thiab lub foob rau lwm qhov, qhov ntawd tsis txhais tau tias ib qho zoo dua li lwm qhov. Nws tsuas yog txhais tau tias lawv txhua tus hu cov khoom zoo sib xws los ntawm cov npe sib txawv.
