SAE J517 tus qauv teev hydraulic hose sib txuas, hose sibtham, kev tso npe yam yuav tsum tau ua raws li:
HOSE CONNECTORS
Hydraulic hose yog tsis tshua siv tsis muaj connectors. Hose nrog connectors txuas nrog nquag hu ua hose assemblies. Qhov kev dav thiab qhov dav rau cov hydraulic hose connectors yog hauv SAE J516. SAE J516 connectors raug qhia los ntawm cov cai tswj raws li teev hauv SAE J846. Hose code, raws li SAE J846, rau siv nrog lawv tus connectors yog muaj nyob hauv Appendix B.
SAE J1475 duav npog thiab kev ua haujlwm rau cov hydraulic hose connectors thaum siv rau hauv cov ntaub ntawv hauv marine.
HOSE LOSSIS
Hose assemblies tej zaum yuav muab los ntawm cov khw, tus neeg sawv cev rau lossis tus qhua ntawm lub khw, los yog los ntawm tus neeg siv.
Fabrication ntawm connectors mus tas li mus hydraulic hose yuav tsum tau tshwj xeeb kev sib txuas khoom. Field txuas txuas connectors (lub plhaub style thiab ntu clamp style) tuaj yeem raug muab tso ua ke tsis muaj cov cuab yeej tshwj xeeb txawm hais tias ntau lub tuam txhab muab khoom siv los pab rau txoj haujlwm no.
DAIM NTAWV TSO CAI
Hydraulic hose assemblies muaj lub neej muaj tseeb thiab lwm yam uas yuav txo tau txoj sia xws li:
a. Flexing lub hose rau tsawg tshaj li qhov teev tseg yam tsawg kawg khoov vojvoog
b. Sib sib zog, rub, sib tsoo, crushing, los yog abrading lub qhov dej
c. Kev khiav hauj lwm saum toj kawg nkaus thiab qis tshaj qhov ntsuas kub
d. Muab lub hose kom ua kom muaj kev ntxhov siab tshaj qhov siab ua haujlwm siab
e. Intermixing hose, connectors, lossis cov khoom siv sib dhos tsis txuas lus los ntawm lub khw los yog tsis ua raws li cov lus qhia cov lus qhia rau fabricating hose assemblies
Kev nyuaj siab ntsws, muab sau rau hauv cov khoom d, yog muaj kev kub ntxhov ceev thiab kev nce hauv siab. Tshaj tawm hauv siab yuav tsis qhia rau ntau qhov kev ntsuas siab tshaj thiab tuaj yeem raug txheeb tau los ntawm kev ntsuas hluav taws xob uas muaj kev teb ntau.
Xa mus rau SAE J1273 yog xav paub ntxiv txog daim ntawv thov.
Cov lus samfwm kom ua rau txhua kab 100R series yog cov ncauj lus kom ntxaws rau hauv daim ntawv no. Cov txheej txheem tshwj xeeb rau kev ua txhua qhov kev xeem muaj nyob hauv SAE J343. Cov kev ntsuam xyuas tau muab qhia rau lub hauv paus rau qhov kev muaj peev xwm ntawm kev sib koom tes los ntawm kev tswj cov kab mob. Nws pom tau tias cov hydraulic systems yuav tsis tshua sib txuam cov kev kuaj no tsis muaj tseeb. Tus hydraulic designer yuav tsum xav txog qhov kev zov me nyuam cov teeb meem ntawm lub rooj sib zog sib dhos thiab txheeb xyuas cov neeg
xav tau nrog cov kev cai tswjfwm, nrog rau kev txhawj xeeb rau qhov zaus thiab qhov siab ntawm kev hloov siab. Ceev ceev cycling nrog tus xa rov qab rau zero accelerates qaug zog failures.
