Imbaraga zo guhuza amakarito yikarito bivuga imbaraga ntarengwa zo gutandukanya impapuro zo hejuru, impapuro zometseho cyangwa impapuro zifatizo hamwe nimpinga ya ruswa ishobora kwihanganira nyuma yikarito ikozwe. GB / T6544-2008 Umugereka B ugaragaza ko imbaraga zifatika nimbaraga zisabwa gutandukanya uburebure bwimyironge yuburebure bwikarito ikarito mugihe cyibizamini byagenwe. Bizwi kandi nk'imbaraga z'igishishwa, zigaragara muri Newtons kuri metero (Leng) (N / m). Nibyingenzi byingenzi bifatika byerekana ubwiza bwikarito ihuza amakarito, kandi nikimwe mubimenyetso byingenzi bya tekiniki yo gusuzuma imiterere yibisanduku. Ubwiza bwiza bwo guhuza bushobora kunoza imbaraga zo guhonyora, imbaraga zo guhonyora, imbaraga zo gutobora nibindi bipimo bifatika byerekana agasanduku. Kubwibyo, ikizamini cyukuri cyingufu zahujwe cyabaye igice cyingenzi mugusuzuma ubuziranenge bwibisanduku, kandi ni ngombwa kubishimangira, kugirango hamenyekane neza niba ubuziranenge bwibisanduku byujuje ibisabwa cyangwa butabishoboye.
Ihame ryo kugerageza amakarito yububiko bwimbaraga nugushiramo ibikoresho bimeze nkurushinge hagati yikarito yikarito hamwe nimpapuro zo hejuru (imbere) zicyitegererezo (cyangwa hagati yikarito yikarito hamwe namakarito yo hagati), hanyuma ukande ibikoresho bimeze nkurushinge. Byinjijwemo na sample. , itume ikora igereranije kugeza itandukanijwe nigice cyatandukanijwe. Muri iki gihe, imbaraga ntarengwa zo gutandukana impinga ya mpapuro nimpapuro zo mumaso cyangwa impinga ya ruguru hamwe nimpapuro zomurongo hamwe nimpapuro zifatanije hamwe bibarwa na formula, nigiciro cyinguzanyo. Imbaraga zikoreshwa zikoreshwa mugushyiramo hejuru no hepfo yinkoni zometseho, ubwo bushakashatsi rero nabwo bwitwa pin guhuza imbaraga. Igikoresho cyakoreshejwe nigeragezwa ryingufu zogusunika, zigomba kuba zujuje ibyangombwa bya tekiniki yipimisha imbaraga zipimisha zerekanwe muri GB / T6546. Igikoresho cyicyitegererezo kigomba kubahiriza gukata nibisabwa muri GB / T6546. Umugereka ugizwe nigice cyo hejuru cyumugereka nigice cyo hepfo cyumugereka, kandi nigikoresho gikoresha igitutu kimwe kuri buri gice gifatika cyicyitegererezo. Buri gice cyumugereka kigizwe nigice cyubwoko bwa pin hamwe nigice cyo gushyigikirwa cyinjijwe kimwe hagati yikarito yikarito yikarito, kandi gutandukana kuburinganire hagati yubwoko bwa pin nigice cyo gushyigikira bigomba kuba munsi ya 1%.
Uburyo bwikizamini cyimbaraga zifatika: Kora ikizamini ukurikije ibisabwa kumugereka B "Kumenya imbaraga zifatika zamakarito yanduye" murwego rwigihugu GB / T 6544-2008. Icyitegererezo cy’icyitegererezo kizakorwa hakurikijwe GB / T 450.Gukora no gupima ingero n’ibidukikije bizakorwa hashingiwe ku bisabwa na GB / T 10739, kandi ubushyuhe n’ubushuhe bizagenwa cyane. Gutegura icyitegererezo bigomba guca amakarito 10 yikarito imwe, cyangwa amakarito 20 yikubye kabiri cyangwa ikarito 30 yikubye inshuro eshatu (25 ± 0.5) mm × (100 ± 1) mm icyitegererezo uhereye ku cyitegererezo, kandi icyerekezo gikonjesha kigomba kuba kimwe nki icyerekezo gito. Bikurikiranye. Mugihe cyikizamini, banza ushyire icyitegererezo kugirango gipimwe mubikoresho, shyiramo ibikoresho bimeze nkurushinge hamwe nimirongo ibiri yinkoni zicyuma hagati yimpapuro zo hejuru hamwe nimpapuro yibanze yicyitegererezo, hanyuma uhuze inkingi yinkunga, witondere kutangiza. icyitegererezo, nkuko bigaragara ku gishushanyo gikurikira. Erekana. Noneho ubishyire hagati ya platine yo hepfo ya compressor. Tangira compressor hanyuma ukande kumugereka hamwe nicyitegererezo ku muvuduko wa (12.5 ± 2,5) mm / min kugeza igihe impinga nimpapuro zo mumaso (cyangwa umurongo / impapuro zo hagati) zitandukanijwe. Andika imbaraga ntarengwa zerekanwe kuri 1N hafi. Gutandukana kwerekanwe iburyo ku gishushanyo gikurikira ni ugutandukanya impapuro zometseho impapuro. Hashyizweho inshinge 7 zose, zitandukanya neza 6. Ku ikarito imwe isukuye, imbaraga zo gutandukanya impapuro zo hejuru nimpapuro zometseho, hamwe nimpapuro zometse hamwe nimpapuro zometseho bigomba kugeragezwa inshuro 5, hamwe ninshuro 10; Imbaraga zo gutandukanya impapuro, impapuro ziciriritse nimpapuro zometseho 2, impapuro zometseho 2 nimpapuro zipimwa bipimwa inshuro 5 buri umwe, inshuro 20 zose; amakarito atatu yikarito agomba gupimwa inshuro 30 zose hamwe. Kubara impuzandengo yagaciro yingufu zo gutandukanya buri cyiciro gifatika, hanyuma ubare imbaraga zifatika za buri cyiciro gifatika, hanyuma amaherezo ufate agaciro ntarengwa kimbaraga zifatika za buri gice gifata nkimbaraga zifatika zubuyobozi, hanyuma ukomeze ibisubizo kugeza ku mibare itatu ikomeye. .
