Txij lub Cuaj Hlis 1, 2018, "Cov Txheej Txheem Txheej Txheem rau Hlau Hlau Ropes" GB / T 20118-2017 hloov "Round Strand Steel Wire Ropes" GB 1102-74. Muab piv ob qho saum toj nosteel hlau hlua qauv, peb pom qhov sib txawv hauv qab no.
1. Sib txawv nominal tensile zog
Hauv GB 1102-74, lub nominal tensile lub zog ntawm steel hlau muab faib ua 5 theem: 140kg/mm2, 155kg/mm2, 170kg/mm2, 185kg/mm2, 200kg/mm2; nyob rau hauv GB / T 20118-2017, lub nominal tensile zog ntawm steel hlau Muab faib ua 3 theem: 1570N/mm2, 1770N/mm2, 1960N/mm2.
2. Lo lus "sib npaug ntawm cov hlau tawg tensile quab yuam" yog tsis siv lawm.
Lo lus "sib npaug ntawm kev sib tsoo ntawm cov hlau xaim" hauv GB 1102-74 yog tsis siv lawm vim muaj kev hloov pauv hauv cov qauv hlau hlua hlau. Es tsis txhob, lo lus "yam tsawg kawg nkaus nro ntawm steel hlau ropes" yog siv.
3. Tsis muaj ntau qhov sib npaug los ntawm "kev hloov pauv hloov pauv"
Vim qhov kev hloov pauv hauv cov qauv hlau hlua hlau, "tsawg kawg ntawm kev sib tsoo ntawm cov hlua hlau" hloov "qhov sib npaug ntawm kev sib tsoo ntawm cov hlau xaim", yog li ntawd, nws tsis muab ntau dua los ntawm qhov hloov pauv.
4. Cov kev hloov pauv hauv cov hlua hlau txoj kab uas hla
Hauv GB 1102-74, qee txoj kab uas hla ntawm 6 × 37 steel hlau hlua tsis muaj nyob hauv GB / T 20118-2017, thiab cov hlua hlau hlua nrog lwm cov kab tau ntxiv lawm.
5. Kev sib txawv ntawm kev kos cov hlua hlau
Yav dhau los: Hlau hlua 6 × 37-15 0-170- lub teeb-sab tes GB 1102-74
Tam sim no: 15 6 × 37M-FC 1770 U sZ GB/T 20118-2017
