Cov keeb kwm luv luv ntawm txoj kev loj hlob ntawm Tuam Tshoj lub sealing engineering technology (I)
Keeb kwm ntawm txoj kev loj hlob ntawm cov roj hmab thiab yas ntsaws ruaj ruaj nyob rau hauv Tuam Tshoj yog luv heev, thaum lub teb chaws tsim, cov roj hmab thiab yas sealing kev lag luam tsuas yog ib tug dawb paug.Lub hnub nyoog kub tiag tiag ntawm Tuam Tshoj txoj kev lag luam roj hmab thiab yas yog tom qab kev hloov kho thiab qhib.Hnub no kuv yuav qhia koj txog keeb kwm ntawm kev txhim kho engineering sealing tshuab nrog lub ntsiab lus ntawm cov roj hmab thiab cov yas ntsaws ruaj ruaj hauv Suav teb.
Ua ntej, pib theem ntawm engineering sealing tshuab
Thaum lub sij hawm lub sij hawm no ntawm Tuam Tshoj txoj kev tsim machinery khoom hydraulic system ua hauj lwm siab yog roughly 12-14MPa.siv sealing system nrog cov ntsaws ruaj ruaj yog: 0-shaped roj hmab foob (NBR);hlau plhaub ib cowhide rotary roj foob;corrugated steel kaum cork kaum hlau caij nplooj ntoos hlav kawg foob;ntim asbestos;asbestos kaum roj hmab sealing gasket;V-shaped foob (cowhide kaum phenolic kaum roj hmab ntoo);V-shaped foob (NBR kaum clip Fabric]: mos yuav yog cov genus sealing gaskets thiab lwm yam.
Thib ob, pib-up theem ntawm engineering sealing tshuab
Lub sijhawm no, kev tsim khoom ntawm Tuam Tshoj cov khoom tseem ceeb ntawm kev tsim kho tshuab hydraulic system ua haujlwm siab yog kwv yees li 14-3.5MPa.nws cov sealing system siv nyob rau hauv cov ntsaws ruaj ruaj rau roj hmab thiab yas ntsaws ruaj ruaj yog lub ntsiab, tshem tawm cov cowhide, asbestos fiber thiab corrugated steel kaum cork kawg seals.Lub ntsiab hom D yog: 0-shaped seal (NBR, FKM);crawler D chassis nrog ntab roj foob (hlau nplhaib qhuav 0-puab daim duab);D puab pob txha pob txha teb roj foob Chuan BR, FKM, ZACM).Hydraulic thiab pneumatic reciprocating motion seals D yog 0-zoo li tus foob (NBR, FKM);U-shaped ntom D txhaj nplhaib (NBR, AU, BU): V-shaped foob (NBR kaum sandwich ntaub);khob-zoo li tus foob (NBR kaum sandwich ntaub), thiab lwm yam.
Nyob rau hauv no 10 xyoo, nyob rau hauv thiaj li yuav ua tau raws li txoj kev loj hlob xav tau kev pab xws li kev tsim machinery, forging thiab nias machinery, thiab lwm yam. siv nruab nrab thiab siab siab hydraulic technology, lub qub Ministry of Machinery teeb tsa xya kev cob qha roj hmab thiab yas seals ntau lawm cog.Tsis tas li ntawd, txhawm rau txhawb kev txhim kho kev sib khi thev naus laus zis hauv Suav teb, "National Technical Committee for Standardization of Hydraulic thiab Pneumatics I thiab National Technical Committee for Standardization of Hydraulics and Pneumatics Rubber and Plastic Seals Standardization Sub-Technical Committee" (cuam tshuam mus rau lub qub ISO/TCI3/SC7) tau tsim nyob rau hauv 1975 thiab 1979, raws li zoo raws li lub koom haum ntawm Friction Fluid (xws li qub ISO/TCI3/SC7) thiab Friction Society Fluid Seals Sub-Technical Committee.
