Uwitekaurunigi hubya excavator ifite umutwaro ukomeye mubikorwa byo gukora.Iyo excavator ihengamye, imihangayiko iba itameze neza.Muri rusange, iyo moteri ikora kuri 350.000 h cyangwa irenga, amenyo yumunyururu hub sprokcet amenyo ashobora gusenyuka cyangwa kumeneka, kandi imiterere y amenyo yambara hamwe nibintu byavunitse amenyo mugice hamwe. mu bice bibiri byurunigi hub sprocket irakomeye cyane.Yagaragaye mubikorwa ko gukoresha insinga yo gusudira kugirango usane ibikoresho byimpeta byoroshye kandi byihuse, kandi birashobora kwemeza imikorere yimashini yose.
Ukurikije ibyangiritse byurunigi rwihuriro, menya aho umwobo uhagaze nigice cyangiritse kigomba gusimburwa, hanyuma ukata igice cy amenyo kugirango gisimburwe no guca gaze.Kora insimburangingo ukurikije ibice bya spock bigomba gusanwa, cyangwa ukata igice cyiza cy amenyo yisoko uhereye mugice kijyanye nikindi gikoresho cyimpeta ishaje ufite garanti yikibuga, hanyuma ugabanye imiterere ya groove aho ihurira.menya aho umwobo ushyizemo umwobo, uyikubite kandi uyikosore mugice gikwiranye nuruhererekane rwurunigi hub, hanyuma witondere kugirango umenye neza neza aho umwobo uhagaze.Kugirango umenye neza ko gusudira bifite imbaraga zisumba izindi kandi zishobora kwihanganira ingaruka nini no kunyeganyega, diameter ya mm4 mm ihuriweho na 507 electrode.Electrode igomba gutekwa kuri 1 h kuri 250 ~ 350 ℃ mbere yo kuyikoresha.Ax3500 DC imashini yo gusudira DC DC uburyo bwo gusudira, ubu ni 130 ~ 140 A.
Mbere yo gusudira, shyushya hejuru yo gusudira kugeza kuri 200 ℃ hamwe nimbunda nini 2 yo gusudira gazi.Nyuma yo gusudira inyuma, gusudira kwanyuma gushobora gusya icyahoze ari icyuma, kikaba gifite akamaro ko gukuraho microstructure ikomye yakozwe nuwahoze asudira.Kubera ko igikoni ari nini, gusudira kwambere bigomba gusudwa byoroheje kugirango bigabanye ubugari bwuruvange kandi bigabanye ibyuka bya karubone byibyuma.Iyo ukoresheje gusudira, electrode ijya imbere nka 15 ° kandi igana imbere kumurongo ugororotse.Mugihe cyo gufunga arc, hagomba kwitonderwa kuzuza umwobo wa arc kugirango wirinde kubyara icyuho cya arc.Nyuma yo gusudira, byihuse inyundo weld hamwe nimpande zombi ukoresheje inyundo ntoya kugirango woroshye imihangayiko kugeza igihe hazaba hari ahantu hacucitse cyane muri weld .Komeza gusudira iyo gusudira gukonje hafi 200 ℃ .Uburyo bwo gusudira bwa buri gusudira nyuma yo gusudira bwa mbere ni kimwe nubwa mbere.Electrode irashobora guhindagurika gato.Kugirango wirinde imyenge, ntugahungabanye cyane.Nyuma yo gusudira, kugirango ukureho ingirabuzimafatizo zikomeye hamwe n’imihangayiko, icyuma cyo gusudira hamwe n'impande zombi gishyuha kugeza kuri 600 ~ 650 ℃ hamwe na acide acetylene, kandi ubushyuhe bukabikwa kuri 20 min.Noneho, ikidodo cyo gusudira gitwikiriwe na asibesitosi, ifu ya lime hydrated cyangwa umucanga wumye, kandi ikidodo cyo gusudira gikonjeshwa buhoro buhoro kugeza ubushyuhe bwicyumba. Koresha uruziga rusya kugirango usukure, kugirango gusana urunigi rwuzuye.
