GB / T 9948-2013 Icyiciro cya 1Cr2Mo Imiyoboro ya peteroli yamenagura imiyoboro idafite ibyuma

Ibisobanuro bigufi:

Umuyoboro wa peteroli ni umuyoboro, muremure, uzengurutse umuyoboro w'icyuma.Gukoresha imiyoboro yameneka ya peteroli: Ikoreshwa mugutwara lisansi, kerosene, amavuta ya mazutu nibindi bicuruzwa bya peteroli, bishobora kurwanya ruswa no kwambara.Umuyoboro wa peteroli (gb9948-83) numuyoboro wambere wicyuma ubereye gucukura geologiya no gucukura inganda.

Kumenyekanisha ibicuruzwa

Ibikomoka kuri peteroli ikata ibicuruzwa, gucuruza peteroli, gutunganya peteroli, umuyoboro wa peteroli ukoreshwa cyane cyane mu gukora umuvuduko ukabije kandi hejuru yumuvuduko ukabije wogukora ibyuma byubwubatsi bwa karubone nziza cyane, ibyuma byubatswe byubatswe hamwe nicyuma kitarwanya ubushyuhe bwumuvuduko mwinshi utagira kashe, ibi imiyoboro ya boiler ikora munsi yubushyuhe bwinshi nigitutu, umuyoboro mugikorwa cya gazi yubushyuhe bwo hejuru hamwe numwuka wamazi nabyo bizaba okiside hamwe na ruswa, bityo umuyoboro wa peteroli urasabwa kugira imbaraga zirambye Kubwibyo, rero, umuyoboro wa peteroli urasabwa ufite imbaraga zo kwihangana cyane, kurwanya okiside nyinshi, hamwe no gutuza neza.

Gukomera kw'imiyoboro ya peteroli yamenetse bigira ingaruka zikomeye kumiterere yubukanishi, ariko ntabwo ibice byose byubukanishi bigomba gukomera rwose.Kurugero, kunama, torsion stress shaft ibice, ibice byo kuvura ubushyuhe hejuru, nibindi, bikenera gusa ubujyakuzimu bunini bwurwego rukomeye kugirango byuzuze ibisabwa kugirango ukoreshwe.Kuzimya umuyoboro wa peteroli uterwa ahanini nigipimo gikomeye cyo gukonjesha, uko igipimo cyo gukonjesha gikabije, niko kuzimya imiyoboro yameneka peteroli, naho ubundi, niko kuzimya umuyoboro wa peteroli ucika.Usibye Co, ibyinshi mubintu bivangavanze birashobora kunoza cyane gukomera kwicyuma.

Intangiriro y'Isoko

Ibikomoka kuri peteroli yamenagura isoko hejuru no hepfo, umukino muremure kandi mugufi urakomeye, isoko rivanze no kugabanuka, ari nako byatumye habaho kwiyongera kwimyumvire yo gutegereza-kubona, isoko ryahagaritswe.Nkumunsi wanyuma wubucuruzi mbere yikiruhuko ibiciro byigihe kizaza bikagabanuka, kandi nta bicuruzwa byigihe kizaza mugihe cyibiruhuko, kubwibyo, isoko ryafunguwe kumunsi wa 10 ejo hazaza haracyariho gukomeza kugabanuka kwabaye.Niba ejo hazaza hagiye hasi, mugihe habuze inkuru nziza yo kongera amahirwe yo kuba isoko ya peteroli yameneka isoko yo gukurikira igabanuka ryiyongereye, ibiciro bya peteroli yamenetse biteganijwe ko bizagenda nabi.
