Ko Makaka Pamisoro yeBolt Zvinorevei?

Magiredhi ekuita mabhaudhi anonyanyozivikanwa aripo parizvino igiredhi remetric rakaiswa neISO, iro rine nhamba mbiri dzakapatsanurwa nedoti uye rinowanzoiswa pamusoro kana parutivi rwebhaudhi musoro kana nati. Akanyanya kuwanda ndi8.8, 10.9 uye 12.9.

Wanza nhamba pamberi penzvimbo yedesimali nezana kuti upe hunenge hudiki hwekusimba kwebhaudhi. Nhamba mushure medesimali poindi yakapetwa negumi inopa fungidziro yesimba regoho zvichienzaniswa neshongedzo yesimba shoma. Semuenzaniso, simba rekusimba regiredhi 8.8 rinenge 800MPa, uye simba regoho rinoita 800*80%=640MPa. Iwe unogona kunge wakaonawo maviri logos pazasi.

Uku ndiko kumaka kwemabhaudhi esimbi asina tsvina kana nzungu, A2 inomirira304 simbi isina tsvinauye A4 inomirira 316 simbi isina tsvina. Nhamba inotevera inomiririra kusimba kwesimba uye ichasiyana zvichienderana nekusimba kwesimba rebhoti. Semuyenzaniso, makumi manomwe zvinoreva kuti simba rekusimba rakaenzana ne700MPa general stainless simbi. Masimbi ese ari maviri asina kunaka ane corrosion resistance, 316 iri nani pane 304, uye inokodzera nzvimbo dzine zvakakwirira zvinodiwa.

Iwe unogona kunge uchine mibvunzo, nei pasina mamakisi pane mamwe mabhaudhi misoro? Izvozvo zvinowanzoreva kuti kushanda kwebhoti kwakaderera, zvakadai sezinga 4.8 kana nhanho 5.8, iyo inowanzosanyorwa.

Iyo kambani inopa tekinoroji kubvunzana uye mushure-yekutengesa sevhisi, uye yakazvipira kushandira vatengesi vakuru, vatengesi vezvitoro, uye makambani einjiniya efekitori kutenderera pasirese. Isu tinokwanisa kugadzirisa marudzi akasiyana-siyana ezvitsigiro uye zvisiri-yakajairwa zvikamu zvinoenderana nezvinodiwa nevatengi, uye nekupa zvinotsigira zvekusimbisa kune vatengi mumaindasitiri akasiyana. Isu tinotenda mu "kupona nemhando, kuvandudza tekinoroji innovation + sevhisi". Kuwana kwedu kukuru kuwana kuvimba kwako uye kuve wako-yekumira fastener mutengesi uye wenguva refu mudiwa.
