Lub neej ntawm cov kab ntawv qhia kev tsheb ciav hlau yog qhov sib txawv heev, txawm tias cov khoom tsim nyob rau hauv tib batch yog siv nyob rau hauv tib lub zog, lub neej yuav txawv; Qhov no feem ntau yog vim muaj kev hloov pauv hauv cov yam ntxwv qaug zog ntawm cov khoom nws tus kheej. Yog li ntawd, txhawm rau txheeb xyuas lub neej ntawm cov kab ntawv qhia kev tsheb ciav hlau, qhov ntsuas lub neej feem ntau yog coj los ua tus qauv ntsuas; Nws lub ntsiab lus yog: tag nrho cov kev khiav hauj lwm deb uas ib batch ntawm tib yam khoom muaj peev xwm khiav nyob rau hauv tib yam mob thiab rated load ib tug los ntawm ib tug, thiab 90 feem pua ntawm lawv tsis muaj deg tev tshwm sim. Lub ntsiab yam tseem ceeb cuam tshuam rau kev pab cuam lub neej ntawm linear qhia rail yog hardness, kub thiab load.
1. Hardness coefficient
Lub hardness ntawm cov hlaws hu rau saum npoo ntawm cov kab qhia kev tsheb ciav hlau yuav tsum yog HRC 58-62 ntawm qhov tob tob. Yog tias tus nqi hardness tsis tuaj yeem ncav cuag qhov xav tau, qhov ntsuas qhov hnyav thiab kev pabcuam lub neej ntawm cov kab qhia kev tsheb ciav hlau yuav raug txo. Nyob rau lub sijhawm no, dynamic thiab zoo li qub rated loads yog qhov tseem ceeb teev nyob rau hauv daim ntawv dimension thiab muab faib los ntawm qhov sib thooj hardness coefficient.
2. Kub coefficient
Qhov ntsuas kub ntawm qhov system yuav cuam tshuam rau cov khoom siv ntawm cov kab qhia kev tsheb ciav hlau. Thaum qhov kub siab tshaj 100 degree, qhov ntsuas load thiab kev pab cuam lub neej ntawm cov kab qhia kev tsheb nqaj hlau yuav raug txo. Nyob rau lub sijhawm no, dynamic thiab static rated load yog tus nqi teev nyob rau hauv lub dimension lub rooj thiab muab faib los ntawm qhov sib thooj kub coefficient. Vim tias qee qhov fittings yog ua los ntawm cov ntaub ntawv yas, lawv tsis tiv taus qhov kub thiab txias, yog li nws tau pom zoo tias qhov kub yuav tsum qis dua 100 degree.
3. Load factor
Cov loads ua rau ntawm txoj kab qhia kev tsheb ciav hlau suav nrog qhov hnyav ntawm lub cuab yeej nws tus kheej, lub zog inertia thaum pib thiab nres, thiab lub sijhawm thauj khoom los ntawm kev ncua, nrog rau kev vibration thiab cuam tshuam nrog kev txav mus los. Hom load no tsis yooj yim rau xam. Raws li qhov kev paub dhau los, nws tau pom tias qhov ntsuas tus nqi thauj khoom tau muab faib los ntawm cov khoom thauj khoom raws li qhov xwm txheej thauj khoom thiab kev pabcuam ceev.
