Heerarka Madaxa Bolts ee Birta Aan Lahayn
Sharaxaada
bolts madaxa flange waxaa loo isticmaalaa in la isku xidho laba ama in ka badan oo qaybood si ay u sameeyaan shir ama sababtoo ah looma soo saari karo sida qayb keliya ama si ay u oggolaadaan dayactirka iyo dayactirka kala furfuri.waxay leeyihiin madax flange waxayna wataan dunta mishiinada si adag oo wax looga qabto.Waxay ku yimaadaan tiro balaadhan oo ah cabbirrada madaxa flange kala duwan ee codsiyada gaarka ah iyadoo ku xiran shuruudaha cabbirkooda.Kuwan boolal madaxa flange iman birta aan daxalka lahayn, birta daawaha iyo qalabka steel carbon kaas oo hubiya in qaab-dhismeedka ma daciifin sababtoo ah miridhku.Iyada oo ku xidhan dhererka boodhka, waxay la iman kartaa dunta caadiga ah ama dunta buuxda.
CODSIGA
boolalka madaxa flange waxaa loo isticmaali karaa codsiyo badan oo kala duwan oo ay ku jiraan xidhashada alwaax, birta, iyo qalabka kale ee dhismaha ee mashaariicda sida saldhigyada, buundooyinka, dhismayaasha jidad weyn, iyo dhismayaasha.
Biraha birta ah ee madow-oxide ayaa si khafiif ah u adkaysta daxalka meelaha qalalan.Biraha birta ah ee Zinc-plated ayaa iska caabiya daxalka deegaanka qoyan.Biraha birta dahaarka leh ee ultra-daxalka leh ee madow waxay iska caabiyaan kiimikooyinka waxayna u adkeystaan 1,000 saacadood oo cusbo ah.dooro boolaladan haddi aanad garanayn dunta halkii inchba.Duubyada fiican iyo kuwa fican ayaa si dhow u kala fogaaday si looga hortago inay ka dabciyaan gariir;duntu way sii fiicnaanaysaa.
Madaxa boolka waxaa loogu talagalay inuu ku dhejiyo roodhida ama wiishka torque spanner taasoo kuu ogolaanaysa inaad xoojiso bolt si aad u qeexdo.Dhalooyinka 2 waxay u muuqdaan in loo isticmaalo dhismaha si loogu daro qaybaha alwaax.Fasalka 4.8 boolal waxaa loo isticmaalaa matoorada yaryar.Fasalka 8.8 10.9 ama 12.9 boolal waxay bixiyaan xoog xajin sare leh.Mid ka mid ah faa'iidooyinka xirayaasha boolalku waxay leeyihiin in ka badan alxanka ama rivets waa inay u oggolaadaan in si fudud loo kala furfuro dayactirka iyo dayactirka.
