Qhia
Cov txheej txheem sealing siv los nres cov kua, lossis cov pa xau yog hu ua dej sealing, feem ntau hu ua waterproof sealing. Nws yog dav siv nyob rau hauv ntau yam khoom siv kho tshuab thiab kev tsim kho, tshwj xeeb tshaj yog thaum muaj roj pov thawj los yog dej tsis zoo. Cov ntawv tshaj tawm no yuav muab cov lus qhia ntxaws ntxaws txog hom, kev siv, cov ntsiab lus, thiab kev tu cov txheej txheem ntawm cov dej ntsaws ruaj ruaj.
Yuav ua li cas dej foob ua haujlwm
Lub foob dej ua haujlwm ntawm lub tswv yim ncaj nraim: lub siab yog siv rau ntawm qhov chaw sib txuas los ntawm cov khoom sib khi, tsim kom muaj qhov thaiv kom tsis txhob muaj dej hla. Cov khoom sib khi no tuaj yeem yog cov khoom siv hlau, lub nplhaib roj hmab, lossis cov khoom siv hloov tau yooj yim uas tuaj yeem khaws cov sealing kev ua tau zoo txawm tias qhov chaw sib chwv hloov pauv zoo li qub lossis tsis muaj zog.
Hom dej foob
1. O-ring: Ib qho dej foob yog ib qho O-ring. Lub nplhaib roj hmab no yog puag ncig thiab tuaj yeem siv los kaw ntau yam xwm txheej. O-rings muab cov txiaj ntsig hauv qab no: tus nqi qis, kev tsim kho yooj yim, thiab kev sib raug zoo nrog ntau yam xov xwm.
2. V-ring: Ib lub nplhaib roj hmab siv rau kev sib khi siab yog hu ua V-ring. Nws hla ntu yog V-zoo li tus, thiab nws ua tau zoo thaum sib khi nyob rau hauv siab. V-rings feem ntau pom nyob rau hauv pneumatic thiab hydraulic systems.
3. Mechanical seal: Hom dej sealing no yog qhov sib txawv thiab feem ntau muaj ntau qhov chaw, xws li cov springs thiab floating rings. High-speed rotating shafts raws li zoo raws li high-temperature thiab high-pressure kev khiav hauj lwm ib puag ncig yog haum rau mechanical seals.
4. Kev ntim khoom ntim: Cov txheej txheem no suav nrog qhov chaw nruab nrab ntawm ob qhov chaw sib cuag nrog cov muab tub lim (xws li asbestos, polytetrafluoroethylene, thiab lwm yam) thiab compressing lub muab tub lim los tsim sealing. Cov ntsaws ruaj ruaj yog nquag siv rau cov khoom sib khi, nrog rau cov twj thiab li qub.
Kev siv dej foob
Hauv kev ua neej txhua hnub thiab kev lag luam, cov dej foob feem ntau yog siv. Cov dej ntsaws ruaj ruaj yog siv rau hauv kev lag luam tshuaj thiab roj av kom tsis txhob muaj tshuaj lom neeg nkag mus; lawv yog siv nyob rau hauv shipbuilding thiab marine engineering kom dej hiav txwv tawm ntawm txhua yam tshuab; thiab lawv tau siv nyob rau hauv kev lag luam automotive los kaw cov cav, kev sib kis, thiab lwm yam khoom. Cov dej xau: Cov dej ntsaws ruaj ruaj yog siv rau hauv cov khoom siv hauv tsev, xws li cov tshuab ntxhua khaub ncaws thiab cov tshuab ntxhua khaub ncaws, kom cov ntsaws ruaj ruaj.
Kev ruaj ntseg dej foob
Kev saib xyuas tsis tu ncua yog tsim nyog los lav cov dej foob qhov ua tau zoo. Kev ntxuav qhov chaw sib cuag, hloov cov dej tsis huv, thiab ntsuas cov dej foob qhov hnav thiab tsim kua muag yog txhua yam piv txwv ntawm kev saib xyuas cov dej num. Xyuas kom tseeb tias cov khoom tshiab uas koj xaiv rau kev hloov pauv dej foob raug teeb tsa kom raug thiab raws li cov lus qhia qub.
Xaus
Dej foob yog txheej txheem sealing tseem ceeb uas yog qhov tseem ceeb rau kev txwv cov kua thiab cov pa tawm. Los ntawm kev nkag siab txog kev xaiv, kev ua haujlwm, thiab kev tu cov txheej txheem ntawm cov dej ntsaws ruaj ruaj, peb tuaj yeem txhim kho kev nyab xeeb thiab kev cia siab ntawm cov cuab yeej siv tshuab thiab siv ntau dua ntawm cov cuab yeej no. Yuav kom tau txais qhov zoo tshaj plaws sealing tshwm sim, txoj cai dej foob hom thiab cov khoom siv yuav tsum tau siv thaum xaiv thiab siv cov sealing dej, suav nrog cov kev xav tau tshwj xeeb thiab cov xwm txheej ua haujlwm.
