Nigute wakora dip ashyushye ya galvanized bolt gushiraho kurushaho

Kwizirika kumutwe biri mubintu byingenzi bigize umuyaga w’umuyaga, ibiraro hamwe n’ibyuma. Usibye ibintu bitandukanye nkibikoresho nibikoresho, coefficient de fraisement hamwe no kugumana insanganyamatsiko muri rusange biterwa cyane nikirere gitandukanye. Umubare wibikoresho bitandukanye bifatanye bifashisha muri iki gihe birimo gukoreshwa: ISO ya bolt, ISO yogushiraho, hamwe na preload ya Calibrated bolt set, byose bigizwe na bolt, byibuze wogeje hamwe nutubuto. Nibisanzwe, bikozwe mubikoresho bikomeye. Coefficient de friction ni ikintu cyingenzi cyibikoresho byizerwa. Agaciro gasobanura igipimo cya preload na torque kandi kigenwa nibintu bibiri: guterana urudodo no guterana umutwe. Umuvuduko wumutwaro ukora hejuru ni preload, nayo ishinzwe kuramba kwa bolt hamwe ningaruka zijyanye nimpeshyi. Torque kurundi ruhande, igira ingaruka hejuru yumurongo nu gice cyo guhuza, kandi igabanijwemo ibice bitatu byumuriro: urudodo rwumutwe, guterana umutwe, nigice gihindurwamo preload. Kubwibyo, preload yanyuma kugirango igere kumurongo wagenwe biterwa na coefficient de friction. Coefficients yo guterana µges na k bigira ingaruka kubintu byinshi bitandukanye nk'imyuka y'ibintu, hejuru, gusiga cyangwa kwambara. Nyamara, ubushyuhe bwibidukikije, ubushuhe nimvura nabyo bigira ingaruka zikomeye kumasano. Hano, ntabwo ihinduka rya elastique gusa ribaho, mubihe bibi cyane bishobora kuganisha ku kogosha kwa bolt cyangwa kunanirwa kugera kubisabwa mbere. Ibi biganisha ku iyubakwa rihagarara nigiciro kinini kandi gutinda gusana cyangwa gusimbuza ibice. Niyo mpamvu DÖRKEN na Peiner Umformtechnik bahisemo gushakira hamwe igisubizo. Peiner niyambere itanga ibyuma bifata ibyuma byumuyaga nububiko bwibyuma, bitanga kalibrasi ya preload bolt kimwe na clamp clamp bolt yubunini bwa M12 kugeza M36. Christos, VP Sales, Coatings Industrial Coatings Tselebidis agira ati: "Ingorabahizi ku mushinga dufatanije kwari uguha ibikoresho bisanzwe bishyushye hamwe n'amashanyarazi adasanzwe, bivuze ko nta mvura cyangwa izuba bizagira ingaruka ku gutuza kwihuta." byasobanuwe. Delken. Ati: "Kugira ngo tubigereho, twakoze ubushakashatsi bwinshi ndetse tunagerageza cyane amakoti ya zinc flake topcoats mu gihe cy'amezi hafi atandatu mbere yo kubona igisubizo cy'ikoti." Mugihe dip hot galvanizing ari primer irinda imiyoboro ihujwe no kwangirika, coefficente yerekanwe yo guteranya ikote rya zinc flake hejuru yemeza ko ibinyomoro byiziritse neza bitarinze gukuraho ikintu na kimwe gishyushye gishyushye. Usibye kwipimisha cyane muri laboratoire, guhuza ibice bimwe na bimwe byagaragaje agaciro kayo mubigeragezo bitandukanye. Umuyobozi w'ishami rishinzwe ubwubatsi n’ingufu z'umuyaga muri Peiner Umformtechnik, Valery Shram agira ati: "Ibisubizo birashimishije - hafi miliyoni 3 za bolt zashyizweho kandi zishyirwaho nta nkomyi." yemeza ko bitigeze bigaragara ko urwego rwizewe rushobora kugerwaho ahazubakwa. ” Claire amaze imyaka icumi akora mu nganda zihuta kandi yiboneye ibintu byose uhereye ku ruganda rukora ibyuma, abakora ibicuruzwa byihuta, abadandaza, ndetse n’amasosiyete akora amashanyarazi, Claire azi kwizirika ku bintu byose.
