1. clip thickness cuam tshuam nws qhov hnyav li cas -rau -strength ratio?
8mm- tuab clips muab qhov hnyav zoo tshaj plaws - rau - lub zog piv rau lub teeb rau nruab nrab loads, muab lub zog txaus ntawm qhov hnyav. Thicker clips (10-12mm) muaj zog dua tab sis qis dua, tsuas yog siv qhov tsim nyog rau cov khoom hnyav.
2. Cov khoom siv dab tsi ua ke hauv "hybrid" clips (steel-polymer) sib npaug zog thiab rwb thaiv tsev?
Hybrid clips siv cov tub ntxhais hlau rau lub zog thiab cov txheej txheem polymer / ntxig rau hluav taws xob rwb thaiv tsev. Qhov no ua ke lub zog clamping ntawm cov hlau (25-30 kN) nrog cov tsis yog - conductivity ntawm polymers, zoo tagnrho rau hluav taws xob hauv nroog rails.
3. Yuav ua li cas "luv-ntev" clips (100–120mm) txo cov khoom pov tseg hauv nqaim- ntsuas kev tsheb ciav hlau?
Cov clips luv luv phim cov flanges me me thiab qhov sib nrug ntawm nqaim- cov kab ntsuas, siv 30-40% cov khoom siv tsawg dua li cov qauv clips. Qhov no txo tus nqi yam tsis muaj kev cuam tshuam kev ua haujlwm hauv qis -load daim ntawv thov.
4. Lub luag haujlwm ntawm clip "camber" (me ntsis upward nkhaus) yog dab tsi hauv kev tswj kev tsheb ciav hlau?
Cambered clips ua rau siab nce siab ntawm txoj kev tsheb ciav hlau flange, kom ntseeg tau kev sib cuag tsis tu ncua txawm tias txoj kev tsheb ciav hlau deflects nyob rau hauv load. Flat clips yuav plam kev sib cuag, txo cov clamping quab yuam los ntawm 10-15% thaum lub sijhawm ua haujlwm siab.
5. Yuav ua li cas "loj-profile" clips (Model LP150) txhim khu kev ruaj ntseg nyob rau hauv hnyav-haul coal kab?
Qauv LP150 muaj 15 hli - thaj tsam sib cuag thiab 12 hli thickness, faib 35-40 kN nro hla ib cheeb tsam loj rail flange. Qhov no tiv thaiv kev hloov tsheb hauv qab 30+ tuj qag loads ntau hauv cov thee thauj.
