Ua ntej, hloov tus qauv rau steel hlau ropes
Cov hlua hlau hlau yuav muaj kev hnav thiab qaug zog tom qab siv ntev, yog li lawv yuav tsum tau hloov raws sijhawm. Yog li, peb yuav txiav txim siab li cas yog tias cov hlua hlau yuav tsum tau hloov? Peb tuaj yeem xav txog cov hauv qab no:
1. Hnav degree: Qhov hnyav dua hnav ntawm cov hlua hlau hlau, nws lub peev xwm thauj khoom qis dua. Feem ntau, yog tias hnav mus txog ntau dua 10% ntawm txoj kab uas hla ntawm cov hlua hlau, nws yuav tsum tau hloov.
2. Buckling qaug zog: Cov hlua hlau hlau yuav txuas ntxiv khoov thaum siv, ua rau qaug zog. Yog hais tias tus naj npawb ntawm cov buckles ntau tshaj ib lub sij hawm, nws yuav tsum tau hloov, feem ntau 50% ntawm cov buckles.
3. Rust degree: xeb ntawm steel hlau ropes tuaj yeem ua rau txo qis hauv lawv lub zog tensile. Yog li ntawd, yog hais tias lub degree ntawm xeb yog heev hnyav, nws yuav tsum tau hloov. Feem ntau, txoj kab uas hla yog 20% ntawm cov xeb hauv zos.
4. Degree ntawm kev puas tsuaj: Yog tias cov hlua hlau hlau puas tsuaj los ntawm cov kab nrib pleb, deformation, los yog cov hlua tawg, nws yuav tsum tau hloov raws sijhawm.
Cov saum toj no yog cov txheej txheem tseem ceeb rau kev txiav txim siab seb puas yuav tsum tau hloov cov hlua hlau steel.
Thib ob, hom kev puas tsuaj ntawm cov hlua hlau
Ntxiv nrog rau cov xwm txheej uas yuav tsum tau hloov pauv tau hais los saum no, kuj tseem muaj qee yam kev puas tsuaj rau cov hlua hlau hlau, suav nrog:
1. Twisting: Cov hlua hlau hlau yuav ntswj thaum siv, feem ntau yog vim yog sab nraud quab yuam. Yog tias twisted hnyav, nws yuav ua rau txo qis hauv lub neej ntawm cov hlua hlau steel.
2. Wrapping: Thaum lub sij hawm siv, steel hlau ropes tej zaum yuav entangled vim kev sib txhuam tsis sib xws ntawm sab hauv thiab sab nrauv ntawm txoj hlua. Yog tias qhov entanglement hnyav dhau lawm, nws tuaj yeem ua rau cov hlua hlau tawg.
3. Kev qaug zog: Tom qab siv sijhawm ntev, cov hlua hlau steel yuav muaj kev qaug zog, uas tuaj yeem ua rau txo qis zog tensile.
4. Xeb: Cov hlua hlau hlau yog qhov yooj yim rau xeb hauv qhov chaw ntub dej, ua rau txo qis zog tensile.
5. Stretching: Cov hlua hlau hlau tsis tu ncua thaum siv, thiab kev ncab ntau dhau los yog nquag tuaj yeem ua rau txo qis zog.
Cov saum toj no yog hom kev puas tsuaj ntawm cov hlua hlau uas yuav tsum tau kuaj xyuas thiab hloov tsis tu ncua.
Hauv luv luv, thaum siv cov hlua hlau hlau, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas lawv cov hnav thiab kev puas tsuaj, thiab hloov lawv raws sijhawm. Kev siv cov hlua hlau tsis raug cai tuaj yeem ua rau muaj kev nyab xeeb zoo.
