Cov Khoom Siv Daim Ntawv Thov rau Tsheb kauj vab System Description
Hauv tsheb kauj vab iav, FFKM (perfluoroelastomer) O-ring khoom siv tau rau cov khoom siv tseem ceeb hauv qab no
Steering kem foob
Lub kauj kem yog cov khoom sib txuas ntawm lub kauj thiab lub kauj mechanism. FFKM O-rings yog siv nyob rau hauv lub steering kem kev sib txuas cov pob qij txha los muab cov khoom sib khi los tiv thaiv cov kua los yog roj.
Lub zog steering twj tso kua mis
Lub hwj chim steering twj tso kua mis yog ib yam khoom uas muab kev pab cuam lub kauj. FFKM O-rings tuaj yeem siv rau kev sib khi ntawm cov twj siv hluav taws xob, suav nrog kev sib txuas ntawm lub twj tso kua mis lub cev thiab lub twj tso kua mis, kom ntseeg tau tias cov kua tsis xau.
Steering mechanism foob
Lub steering mechanism yog ib qho tseem ceeb ntawm kev tswj lub kauj. FFKM O-rings tuaj yeem siv rau hauv kev sib txuas cov pob qij txha ntawm cov kauj tsheb thiab cov ntsaws ruaj ruaj ntawm cov ncej tig los tiv thaiv cov kua dej los yog cov roj nplua nyeem.
Steering rod seal
Lub kauj tsheb kauj vab yog ib qho tseem ceeb ntawm kev xa cov steering commands mus rau lub log. Siv FFKM O-rings ntawm kev sib txuas ntawm cov hlua khi thiab piston rods los xyuas kom meej cov kua lossis roj sealing kev ua tau zoo.
Steering kem adjuster foob
Steering kem adjuster yog ib yam khoom siv los kho qhov siab thiab qaij lub kaum sab xis ntawm lub kauj. FFKM O-rings tuaj yeem siv los kaw cov kauj kem hloov kho kom tsis txhob muaj kua lossis roj.
Daim ntawv thov ntawm FFKM O-ring cov khoom siv hauv cov khoom siv no feem ntau yog ua raws li nws qhov kev ua haujlwm siab kub siab, tshuaj tiv thaiv corrosion thiab kev ua haujlwm zoo sealing. Lawv ua kom muaj kev ua haujlwm zoo ntawm lub kauj tsheb kauj vab, tiv thaiv cov kua dej thiab cov pa tawm, thiab muab kev ntseeg tau ntev thiab kav ntev. Nws yuav tsum raug sau tseg tias cov khoom siv tshwj xeeb ntawm O-ring siv nyob ntawm lub tsheb tsim cov qauv tsim thiab cov lus qhia tshwj xeeb.
DIN 3771 yog dab tsi?
DIN 3771 yog tus qauv tsim los ntawm German Industrial Standardization Organisation (DIN) uas qhia txog qhov ntev thiab cim qhov system rau roj hmab O-rings. Cov txheej txheem no txhais cov kev txwv xws li txoj kab uas hla, ntu tuab, thiab kam rau ua rau O-rings ntawm ntau qhov sib txawv thiab muab cov cim cim rau lawv siv rau hauv kev lag luam thiab engineering.
Raws li tus qauv DIN 3771, qhov loj ntawm O-rings yog qhia nyob rau hauv cov nqe lus ntawm sab hauv txoj kab uas hla thiab cross-sectional txoj kab uas hla, thiab tshwj xeeb cov lis dej num thiab cov zauv yog siv los cim O-rings ntawm ntau qhov sib txawv. Piv txwv li, O-ring cim "12 x 2" txhais tau hais tias nws muaj ib txoj kab uas hla ntawm 12 hli thiab ib txoj kab uas hla ntawm 2 hli.
