GB/T 9948-2013 Fasalka 1Cr2Mo Tubooyinka Shidaalka ee Shidaalka ee Tuubooyinka Birta ah

Sharaxaad Gaaban:

Tuubbada dildilaaca batroolka waa dhuumo bir ah oo bannaan, dheer, wareegsan, oo aan sinaba lahayn.Codsiga dhuumaha dildilaaca batroolka: Waxaa loo isticmaalaa in lagu qaado shidaalka, kerosene, saliidda naaftada iyo waxyaabaha kale ee saliidda, kuwaas oo iska caabin kara daxalka iyo xidhashada.Tuubada dildilaaca batroolka (gb9948-83) waa tuubbo bir ah oo heerka koowaad ah oo ku habboon qodista juqraafiyeed iyo qodista warshadaha.

Tuubbooyinka dildilaaca tafaariiqda, batroolka dildilaaca tuubada goynta, tuubada dildilaaca batroolka waxaa inta badan loo isticmaalaa in lagu soo saaro cadaadis sare iyo cadaadiska ka sarreeya tuubada kuleyliyaha uumiga ee birta qaab dhismeedka tayada sare leh, birta qaab dhismeedka alloy iyo birta kulaylka u adkaysata tuubo cadaadis sare leh, kuwan Tuubooyinka kuleyliyaha waxay ku shaqeeyaan heerkul sare iyo cadaadis, tuubada doorka heerkulka sare ee gaaska qiiqa iyo uumiga biyaha ayaa sidoo kale noqon doona oxidation iyo daxal, sidaas darteed tuubada dildilaaca batroolka ayaa looga baahan yahay inay yeelato xoog waara oo sarreeya Sidaa darteed, tuubada dildilaaca batroolka ayaa loo baahan yahay waxay leeyihiin awood dulqaad sare leh, iska caabin oksaydhism sare leh, iyo xasilooni urureed oo wanaagsan.

Adkeysiga tuubada dildilaaca batroolka ayaa saameyn weyn ku leh sifooyinka farsamada, laakiin dhammaan qaybaha makaanikada waa in si buuxda loo adkeeyo.Tusaale ahaan, foorarsiga, qaybaha usheeda dhexe torsion, qaybaha daaweynta kulaylka dusha, iwm, kaliya waxay u baahan yihiin qoto dheer oo lakab adag si loo buuxiyo shuruudaha isticmaalka.Deminta dhuumaha dildilaaca batroolka waxaa inta badan lagu go'aamiyaa heerka qaboojinta muhiimka ah, marka ay yaraato heerka qaboojinta muhiimka ah, ayaa fiicnaan doonta deminta dhuumaha dildilaaca batroolka, iyo taa beddelkeeda, hoos u dhaca deminta tuubada dildilaaca batroolka.Marka lagu daro Co, inta badan walxaha alloying waxay si weyn u wanaajin karaan adkeynta birta.

Hordhaca Suuqa

Suuqa dhuumaha batroolka ayaa kor iyo hoos u sii riixaya, ugaadha dheer iyo kuwa gaabanba waa mid aad u daran, suuqu waa barar isku dhafan, taas oo sidoo kale keentay koritaanka niyadda sugitaanka, baahida suuqa ayaa la joojiyay.Sida maalinta ugu dambeysa ee ganacsiga ka hor maalmaha fasaxa qiimihiisu hoos u dhaco, oo aan jirin wax ganacsi ah oo mustaqbalka ah inta lagu jiro fasaxa, sidaas darteed, suuqa ayaa furmay 10th mustaqbalka ayaa wali sii socota hoos u dhaca dhacay.Haddii mustaqbalku hoos u dhaco, maqnaanshaha war wanaagsan si kor loogu qaado ixtimaalka suuqa tuubada dildilaaca batroolka si uu ula socdo hoos u dhaca ayaa kordhay, qiimaha tuubooyinka dillaaca batroolka ayaa la filayaa inuu si daciif ah u socdo.
