Isesengura ryubushyuhe buke hamwe nubushyuhe bwo hejuru bwamavuta amavuta

Amavuta yo gusiga amavuta arakwiriye mubisanzwe byihuta kandi biciriritse aho ubushyuhe bwo gukora bwikigereranyo buri munsi yubushyuhe bwamavuta.Nta anti-friction ifite amavuta akwiranye nibisabwa byose.Buri mavuta afite imikorere mike n'ibiranga.Amavuta agizwe namavuta yibanze, kubyimbye ninyongera.Gufata amavuta mubisanzwe birimo peteroli yibanze ya peteroli hamwe nisabune yicyuma runaka.Mu myaka yashize, ibibyimba kama na organic organique byongewe kumavuta yibanze.Imbonerahamwe 26 yerekana muri make ibigize amavuta asanzwe.Imbonerahamwe 26 .Amavuta ashingiye kuri Litiyumu afite byinshi akoreshwa kandi birakwiriye gukoreshwa mu nganda no gutwara ibiziga.
Amavuta yibanze ya sintetike, nka esters, est est organique na silicone, iyo akoreshejwe hamwe nibyuma bikoreshwa cyane hamwe ninyongeramusaruro, ubushyuhe ntarengwa bwo gukora busanzwe buri hejuru yubushyuhe bwo hejuru bwamavuta ashingiye kuri peteroli.Ubushyuhe bwo gukora bwamavuta yubukorikori burashobora kuva kuri -73 ° C kugeza 288 ° C.Ibikurikira nibisanzwe biranga umubyimba ukoreshwa hamwe namavuta ashingiye kuri peteroli.Imbonerahamwe 27. Ibiranga rusange mubyimbye bikoreshwa hamwe namavuta ashingiye kuri peteroli Thickeners Ubusanzwe Ibitonyanga Byihuta Ntarengwa Ubushyuhe bwo Kurwanya Amazi Ukoresheje umubyimba uri mu mbonerahamwe ya 27 hamwe na hydrocarubone ya sintetike cyangwa amavuta ashingiye kuri ester, ubushyuhe ntarengwa bwo gukora burashobora kugerwaho Kwiyongera kuri 10 ° C.

Gukoresha polyurea nkibibyimbye nimwe mubintu byingenzi byateye imbere murwego rwo gusiga amavuta mumyaka irenga 30.Amavuta ya Polyurea yerekana imikorere myiza muburyo butandukanye bwo kwishyiriraho porogaramu, kandi mugihe gito, yamenyekanye nkumupira utwara amavuta mbere.Ubushyuhe buke Mubihe byubushyuhe buke, itangira ryamavuta yo gusiga amavuta ni ngombwa cyane.Amavuta amwe arashobora gukora mubisanzwe mugihe ubwikorezi burimo gukora, ariko bizatera kurwanya birenze urugero gutangira.Mu mashini ntoya, ntishobora gutangira mugihe ubushyuhe buri hasi cyane.Mubikorwa nkibi, birasabwa ko amavuta agira ibiranga ubushyuhe buke butangira.Niba ubushyuhe bukora buringaniye, amavuta yubukorikori afite ibyiza bigaragara.Amavuta arashobora gutuma itangira nogukoresha itara rito cyane kubushyuhe buke bwa -73 ° C.Rimwe na rimwe, ayo mavuta akora neza kuruta amavuta muriyi ngingo.Ingingo y'ingenzi yerekeye amavuta nuko gutangira torque atari byanze bikunze umurimo wo guhuza amavuta cyangwa imikorere muri rusange.Gutangira torque birasa nkigikorwa cyimikorere yamavuta yihariye, kandi bigenwa nuburambe.
Ubushyuhe bwo hejuru: Ubushyuhe bwo hejuru bwamavuta ya kijyambere mubisanzwe nibikorwa byuzuye byubushyuhe bwumuriro no kurwanya okiside yamavuta yibanze hamwe ningaruka za okiside.Ubushyuhe buringaniye bwamavuta bugenwa nigitonyanga cyamavuta yibyibushye hamwe nibigize amavuta yibanze.Imbonerahamwe 28 irerekana ubushyuhe bwamavuta mubihe bitandukanye byamavuta.Nyuma yimyaka myinshi yubushakashatsi hamwe namavuta-amavuta, uburyo bwacyo bwo kwerekana ko ubuzima bwamavuta buzagabanywa kabiri kuri buri 10 ° C kwiyongera kwubushyuhe.Kurugero, niba ubuzima bwa serivisi bwamavuta kubushyuhe bwa 90 ° C ni amasaha 2000, mugihe ubushyuhe buzamutse bugera kuri 100 ° C, ubuzima bwumurimo bugabanuka kugeza kumasaha 1000.Ibinyuranye, nyuma yo kugabanya ubushyuhe kuri 80 ° C, ubuzima bwa serivisi buteganijwe kugera kumasaha 4000.
