SAE J1942_201903 tus qauv yog tsim los ntawm kev sib koom tes ntawm US Coast Guard thiab SAE, pib ua kom tiav Lub Yim Hli 28,19911, raws li daim ntawv pov thawj rau kev sib txuas lus tsis sib haum sib txuas rau kev lag luam kev lag luam.
SAE J1942 Standard yog siv cov kev cai rau ntau yam kev sib txuas ntawm cov dej khov thiab / los yog sib xyaw hauv cov tshuab nruab ntug coj mus kuaj xyuas thiab kos los ntawm US Coast Guard. Nws yog npaj hais tias daim ntawv no tsim cov dej khov thiab cov theem kev ua haujlwm uas tseem ceeb heev rau kev khiav dej num hauv kev nyab xeeb nyob rau hauv qhov chaw kawm. Xa mus rau SAE J1273 kev xaiv, kev teeb tsa, thiab kev saib xyuas ntawm kev sib tham ntawm qhov dej thiab hose.
Xa mus rau SAE J1527 rau lub qhov hos tau siv roj los sis diesel roj rau cov khoom siv me me, nrog rau kev siv khoom zoo nkauj thiab lwm yam khoom lag luam me uas tswj ncaj qha los yog siv raws li 33 CFR 183 Subpart J, thiab tej nkoj nquam thiab yachts ntsib American Nkag thiab Yacht Council cov qauv.
SAE J1942-1 yog cov npe ntawm cov khoom uas tau muab tso rau kev siv rau hauv daim ntawv teev npe hauv SAE J1942, Table 1, rau cov kua fais fab, roj roj, lub roj, dej, thiab pneumatic systems.
SAE J1942 cov ntsiab lus sib piv raws li nram no:
SAE J343 Kev Xeem thiab Kev Xeem Xeem rau SAE 100R Series Hydraulic Hose thiab Hose Assemblies
SAE J517 Hydraulic Hose
SAE J1273 Cov Kev Xyaum Pom Zoo rau Cov Hos Sib Haum Rau Cov Hwj Hos (Hydraulic Hose Assemblies)
SAE J1475 Hydraulic Hose Fitting rau Cov Kev Siv Marine
SAE J1527 Marine roj Hoses
SAE J1942-1 Pheej Hoses rau Cov Ntawv Cog Tseg
ASTM D1141-98 Specification rau Hloov Dej Hiav Txwv
MSHA 30 CFR 18.65 Kev Txuag ntawm Cov Kev Fais Fab thiab Dej - Subchapter B - Cov Kev Cai Raws Kev Cai Tsoom Fwv Teb Chaws Txoj Cai
ISO 15541 Ships thiab Marine Technology - Tua Hluav Taws Xob ntawm Hose Assemblies - Yuav Tsum Tau Tshaj Tawm
HOSE APPLICATION / CONSTRUCTION
SAE J1942 Fittings yuav tsum haum rau SAE J1475 qhov siv rau. Tsuas yog qhov hose thiab haum ob peb ua ke uas tau raug kuaj thiab dhau cov kev cai ntawm daim ntawv no los ua lub rooj sibtham sib xyaw ua haujlwm. Push-on fittings, ceev disconnect couplings thiab fittings nrog ib zaug xwb cab kab iav clamp, los yog ib qho qhwv nyob ib ncig ntawm lub qhov dej yog tsis tsim nyog.
TXOJ HAUJLWM TXHEEJ TXHEEM HAIV TXWV SAE J343 tshwj tsis yog tias tau sau tseg.
IMMERSION-BURST TEST
TSIM NYOG KUAJ XYUAS
TEB CHAWS TUAJ KOM TXHEEJ TWG xws li 2.5 feeb Cov Tshuaj Tua Hluav Taws, 30 Lub Teeb Huab Hluav Taws,
NON-SAE J517 HOSE / HOSE ASSEMBLIES ntsib cov hauv qab no:
a. Daim Ntawv Pov Thawj Ua Ntej ib SAE J343. Tsis pub dim.
b. Hloov qhov ntev ib ntu J343. Tsis pub tshaj 2% thiab -4% (tsis siv rau xov tooj helix hom).
c. Kev Tawm Tsam Ntug Hla Tebchaws ib SAE J343. Qhov tsawg tshaj plaws yuav tsum yog tsawg kawg yog plaub zaug qhov siab tshaj ntawm kev ua haujlwm ntawm qhov dej.
d. Cold Bend Test rau SAE J343. Tsis pub lwm tus ntog los yog tsis pub muaj. Kev ntsuam xyuas kom ua tiav rau ntawm qhov chaw tsim khoom ntsuas kub tsawg.
e. Impulse Test ib SAE J343. Ua qhov kev ntsuam xyuas ntawm 125% ntawm qhov siab tshaj ntawm kev ua haujlwm ntawm qhov dej rau 200000 mus rau ntawm qhov kub ntawm 100 ° C. Tsis pub los yog lwm yam kev ua txhaum cai. (Impulse tsis tas yuav tsum ntawm xov tooj helix-hom hose.)
