ISO 6149 -2 Kev sib txuas rau hydraulic fluid zog thiab kev siv dav - Cov chaw nres nkoj thiab kev sib txuas xaus nrog ISO 261 metric threads thiab O-ring sealing - Ib feem 2: Dimensions, design, test method thiab cov kev cai rau kev ua hauj lwm hnyav (S series)
Qhov no ntawm ISO 6149 qhia txog qhov ntev, qhov yuav tsum ua kom tau thiab cov txheej txheem kev ntsuas rau kev ntsuas kho thiab kho tsis tau-hnyav hnyav (S series) ntawv xaus thiab O-rings.
NQI xaus raws li qhov no ntawm ISO 6149 yuav raug siv rau kev ua haujlwm ntawm kev ua haujlwm txog 63 MPa [630 bar1]] rau kev kawm tsis tiav thiab 40 MPa (400 bar) rau kev ua tiav kev kawm tiav. Qhov tso cai ua haujlwm siab yog nyob ntawm qhov kawg ntawm qhov kev kawm, cov ntaub ntawv, kev tsim, kev ua haujlwm, daim ntawv thov, thiab lwm yam.
Kev ua tiav ntawm cov lus qhia hauv qhov chaw ntawm ISO 6149 tsis tau lees tias qhov kev ua tau zoo. Txhua lub chaw ua haujlwm yuav tsum ua raws li cov lus qhia hauv ntu ntawm ISO 6149 kom paub tseeb tias cov khoom ua raws li kev ua tau zoo.
CEEB TOOM 1 Ib qho tseem ceeb ntawm cov qhab nia tau ua tiav kom paub tseeb tias qhov kev ua tiav ntawm qhov kev sib txuas xaus ntawm cov pa roj carbon.
CEEB TOOM 2 Qhov no ntawm ISO 6149 siv rau cov sib txuas lus hauv ISO 8434-1, ISO 8434-3 thiab ISO 8434-4, thiab cov ntaub ntawv raws li ISO 6149 -4. Saib ISO 12151-4 rau kev sib txuas lus hose haum ua kom tiav.
CEEB TOOM 3 Lub Taw qhia ntawm ntu no ntawm ISO 6149 muab tswv yim rau cov chaw nres nkoj thiab kev kawm sab nraud los siv rau cov qauv tshiab hauv hydraulic fluid daim ntawv sau npe.
