Nubwo bisa nkibintu bito, ibikoresho bya O-impeta ni ngombwa cyane. Ibikoresho birashobora kumenya ubushyuhe bwikimenyetso cya kashe. Iha kandi kashe imiti irwanya imiti, kandi ubwoko bumwebumwe bwa reberi burahuza n'amazi atandukanye. Ibikoresho bibiri bisanzwe kuri ball ball yukuri yubumwe ni Viton na EPDM.

Viton (ku ishusho iburyo) ni reberi ya sintetike ifite imiti myinshi kandi irwanya ubushyuhe. EPDM isobanura Ethylene Propylene Diene Monomer kandi ifite imiterere yihariye ituma iba ibikoresho bya O-ring bizwi cyane. Iyo ugereranije Viton na EPDM, hagomba gutekerezwa ibintu byinshi: kwihanganira ubushyuhe, guhuza imiti, nigiciro. Soma ku kugereranya kwuzuye.

Ikimenyetso cya EPDM
EPDM rubber (EPDM rubber) ni reberi igoye kandi ihendutse ya reberi hamwe nuburyo butandukanye bwo gukoresha. Ubusanzwe ikoreshwa mugukingira amazi kuberako EPDM ifunga neza. Nibikoresho bisanzwe kubidodo bya firigo kuko ni insuliranteri kandi ifite ubukana buke buke. By'umwihariko, EPDM ikora neza mubushyuhe bwa -49F kugeza 293F (-45C kugeza 145C), bigatuma biba byiza mubisabwa mubushyuhe ubwo aribwo bwose.

Mugihe reberi nyinshi irwanya ubushyuhe bwinshi, bike gusa birashobora guhangana nubushyuhe buke nka EPDM. Ibi bituma ihitamo ryambere kubantu bose bagerageza gufunga ahantu hakonje cyangwa nibikoresho bikonje. Ubumwe Bwuzuye Umupira Valves hamweEPDM Ifunze O-ImpetaPorogaramu zisanzwe kuri EPDM zirimo amashanyarazi, imirongo ya pisine, amazi, gukusanya imirasire y'izuba, O-impeta, nibindi byinshi.

Usibye kwihanganira ubushyuhe bwinshi, EPDM ifite imiti myinshi irwanya imiti. Harimo amazi ashyushye, amashyanyarazi, ibikoresho byo kwisiga, ibisubizo bya potasike ya caustic, sodium hydroxide yumuti, amavuta ya silicone / amavuta, nibindi byinshi bivanze na acide na chimique. Ntibikwiye gukoreshwa hamwe namavuta yubutare nkamavuta yo gusiga, amavuta cyangwa lisansi. Kubijyanye na chimique yihariye ya EPDM, kanda hano. Iyi mico itangaje, ihujwe nigiciro cyayo gito, ituma EPDM ikundwa cyane.

Ikimenyetso cya Viton
Viton ni reberi yubukorikori hamwe na fluoropolymer elastomer. "Fluoropolymer" bivuze ko ibi bikoresho bifite imbaraga nyinshi zo guhangana na solide, acide na base. Ijambo "elastomer" rishobora guhinduranya cyane na "rubber". Ntabwo tuzaganira ku itandukaniro riri hagati ya elastomer na rubber hano, ariko tuzaganira kubituma Viton idasanzwe. Ibikoresho bikunze kurangwa nibara ryatsi cyangwa igikara, ariko ikitandukanya rwose nubucucike bwacyo. Ubucucike bwa Viton buri hejuru cyane yubwoko bwinshi bwa reberi, bigatuma kashe ya Viton imwe mubikomeye.

Viton ifite ubushyuhe bwagutse bwo kwihanganira kuva kuri -4F kugeza 410F (-20C kugeza 210C). Ubushyuhe bwo hejuru Viton ishobora kwihanganira butuma biba byiza kubushyuhe bwo hejuru. Viton isanzwe ikoreshwa muri O-impeta, gants zidashobora kwihanganira imiti nibindi bicuruzwa bibumbabumbwe cyangwa bisohotse. O-impeta ikozwe muri Viton ninziza cyane yo kwibira, moteri yimodoka hamwe na valve zitandukanye.

Ku bijyanye no kurwanya imiti, Viton ntagereranywa. Irwanya ruswa ituruka ku bwoko butandukanye bwamazi n’imiti kurusha elastomer idafite florine. Bitandukanye na EPDM, Viton irahuza namavuta, lisansi, amavuta hamwe na acide nyinshi zidasanzwe. Irwanya kandi cyane kwikanyiza, okiside yo mu kirere, urumuri rw'izuba, ikirere, ibicanwa bya moteri ya ogisijeni, aromatique, ibihumyo, ifu, n'ibindi. Irashobora kandi kwihanganira gutwika kurusha izindi reberi. Soma byinshi kubijyanye na dosiye nibidakorwa byimiti ya Viton.

Ikibazo nyamukuru na Viton nigiciro cyacyo. Mu musaruro, bisaba hafi inshuro 8 gukora ibikoresho bingana na EPDM. Mugihe uguze ibicuruzwa birimo umubare muto wibikoresho bya reberi, igiciro ntigishobora gutandukana cyane. Ariko mugihe utumije kubwinshi, urashobora kwitega ko ibice bya Viton bihenze cyane kuruta EPDM.

Ikirango cya Viton na EPDM
Imbonerahamwe ya Viton vs EPDM

Nibihe bikoresho byiza cyane? Ibi bibazo ntabwo ari byiza rwose. Ibikoresho byombi bifite porogaramu zihariye aho zikomeye kuri, byose rero biterwa nakazi bagiye gukora. C.PVC Umupira Kugenzura Indangagacirona CPVC Swing Check Valves irahari hamwe na kashe ya Viton cyangwa kashe ya EPDM. Ikidodo gikozwe muri O-impeta zashyizwe mubikoresho. Iyi mibande yose yashizweho kugirango isenywe byoroshye kugirango ibungabunge byoroshye, bityo ifite imibiri ikurwaho.

Niba ukeneye valve ya sisitemu yamazi, utitaye kubushyuhe, valve ifite kashe ya EPDM mubisanzwe ni byiza guhitamo. Usibye kwihanganira ubushyuhe butandukanye gato, itandukaniro nyamukuru hagati yibikoresho byombi ni imiti irwanya imiti. Viton ninziza yo gukoresha hamwe na lisansi nibindi bikoresho byangirika, ariko mugihe uhuye nikintu kitagira umwere nkamazi, uku kuramba gukabije ntigukenewe.
