SAE J518-2 tus qauv muab cov ntaub ntawv rau Flange Clamps, ntsia hlau, tshuab ntxhua khaub ncaws, o-ring seal raws li nram no:
Flange Clamps
Yuav tsum yog los ntawm cov khoom siv ferrous nrog cov nram qab no cov khoom:
- Tsib khoom tawm lub zog: 415 MPa
- Tsaus elongation ntawm pob txha 3%
Screws
Yog tias tsis muaj lwm tus qhia, siv lub taub hau taub hau los sis lub qhov ntswg lub taub hau ntawm cov khoom ntim 10.9 (yam tsawg), raws li teev hauv ISO 898-1, los yog sib npaug (SAE qib 8 hex taub hau hau ntswj los yog ASME 18.3 qhov ntsaws taub hau taub hau ntawm ASTM A574 khoom ) txhuam. Tig duav ntsug yuav tsum tsis txhob siv rau kev tsim tshiab.
Txuas
Kev siv cov khoom sib xyaw kom tsis zoo yog qhov pom zoo. Cov khoom txuas, yog siv, yuav tsum ua raws li ISO 7089 Type A, Class 300HV thiab raug rau qhov sib huam sib luag tsuas yog DN 32 (-20) hom 2 (nti) qhov siab uas yuav tsum ua raws li ASME 18.22.1 hom B (HV300 ). Taub nrawm ntxuav raws li ASME B18.22.1, hom B ntu (HV300), yuav raug hloov
thaum siv hom 2 screws tshwj tsis yog rau DN 32 (-20) loj. Lub ISO 7089 lub tshuab ntxhua khaub ncaws yuav ua rau cuam tshuam yog siv cov ntiv nplhaib hauv lub DN 32 (-20) loj.
O-ring ntsaws ruaj ruaj
Cov khoom sib txuas ua raws li Lub Ntiaj Teb Kev Txhim Kho Siv cov khoom siv elastomeric. Tshwj tsis yog tias tau teev, cov khoom sib txuas ua ke thiab muab xa nrog elastomeric seals rau siv raws li teev tseg kev ua hauj lwm kub ntau yam nrog roj av hydraulic kua dej. Kev siv cov connectors thiab elastomeric seals nrog lwm cov hydraulic fluids yuav ua rau txo
kev kub ntxhov ua haujlwm lossis muaj peev xwm kav tau cov connectors tsis haum rau daim ntawv thov. Cov lag luam yuav muab, thaum thov, cov khoom sib txuas nrog elastomeric seals rau siv hydraulic cov kua hluav taws xob lwm yam roj av hydraulic cov kua hluav taws xob uas ua tau raws li tau teev tseg kev ua hauj lwm kub ntau ntawm cov connectors.
Cov O-rings hauv Cov Ntxhuav 1A thiab 1B yuav tsum sib haum rau cov me me, kev ua siab ntev A hauv ISO 3601-1 thiab yuav tsum ua tau raws li los yog siab tshaj qhov kev lees txais O-nplua nuj rau qib N ntawm ISO 3601-3. Tshwj tsis yog tias tau teev, tus O-rings yuav tsum yog NBR (nitrile) nrog lub zog ntawm 90 ± 5 IRHD ntsuas raws li ISO 48.
