Dab tsi yog high-strength bolts?
Bolts ua los ntawm cov hlau muaj zog los yog xav tau qhov tseem ceeb ua ntej tuaj yeem raug xa mus rau qhov muaj zog bolts. High dispatch screws feem ntau yog siv rau kev sib txuas txuas hniav, steel rails, high-voltage thiab ultra-high voltage khoom. Qhov tawg ntawm hom ntsia liaj qhov rooj no feem ntau yog nkig. Lub zog muaj zog screws siv rau cov cuab yeej siv siab ultra-siab yuav tsum muaj qhov tseem ceeb prestressing los xyuas kom meej lub sealing ntawm lub thawv.
Qhov txawv ntawm lub zog muaj zog bolts thiab zoo tib yam bolts:
1. Qhov sib txawv ntawm cov khoom siv raw
Lub zog muaj zog bolts yog ua los ntawm cov ntaub ntawv muaj zog. Cov ntsia hlau, txiv ntseej, thiab cov tshuab ntxhua khaub ncaws muaj zog yog txhua yam ua los ntawm cov hlau muaj zog, feem ntau siv hauv 45 # steel, 40 boron steel, thiab 20 manganese steel. Ordinary bolts feem ntau yog ua los ntawm cov pa roj carbon zoo tib yam uas tsis muaj kev kho cua sov.
2. Qhov sib txawv ntawm cov qib zog
Kev siv cov bolts muaj zog tau dhau los ua ntau dua, nrog rau ob theem zog uas feem ntau siv: 8.8s thiab 10.9s, nrog 10.9 feem ntau. Lub zog ntawm cov bolts zoo tib yam yuav tsum qis dua, feem ntau 4.4, 4.8, 5.6, thiab 8.8 qib.
3. Qhov sib txawv ntawm cov yam ntxwv quab yuam
Kev sib txuas ntawm cov ntsia liaj qhov rooj cia siab rau qhov kev tiv thaiv ntawm cov ntsia liaj qhov rooj thiab lub siab muaj peev xwm ntawm lub qhov phab ntsa kom xa cov quab yuam, thaum lub zog siab bolts tsis tsuas yog muaj cov khoom siv siab, tab sis kuj siv lub zog loj ua ntej rau lub bolts, ua rau tswj siab ntawm cov khoom sib txuas, thiab yog li tsim kom muaj kev sib txhuam loj loj perpendicular mus rau cov ntsia hlau kev taw qhia.
4. Qhov sib txawv ntawm kev siv
Cov bolted kev sib txuas ntawm cov khoom tseem ceeb ntawm lub tsev tsim yog feem ntau ua nrog cov bolts muaj zog. Ordinary bolts tuaj yeem rov qab siv tau, thaum lub zog muaj zog bolts tsis tuaj yeem rov qab siv dua. Lub zog muaj zog bolts feem ntau yog siv rau kev sib txuas mus tas li.
