I-Tensile Strength Tester

Umshini wamukela ukulayishwa kwe-hydraulic, isibonisi sekhompyutha, ukusebenza kalula. Isetshenziselwa ikakhulukazi ukuhlolwa kwensimbi, ukucindezelwa, ukugoba nokugoba. Izesekeli ezengeziwe ezilula kanye nemishini ingasetshenziswa ukuhlola izinkuni, ukhonkolo, usimende, irabha, njll. Ifaneleka kakhulu ezinhlobonhlobo zokuqina okuphezulu, ukuqina okuphezulu kwensimbi noma izinto ezingezona ezensimbi ngaphansi kokuhlolwa okukhulu kwamandla omthwalo.

Umshini wokuhlola i-tensile wepulasitiki kanye nezinto zenjoloba uyisisetshenziswa esibalulekile sokuhlola esisetshenziselwa ukuhlola izakhiwo zemishini zepulasitiki nezenjoloba.

Imishini yokuhlola ipulasitiki imvamisa yakhiwa uhlelo lokulayisha, uhlelo lokulinganisa, uhlelo lokulawula kanye nohlelo lokutholwa kwedatha kanye nohlelo lokucubungula. Umgomo wokusebenza uwukukala ukuwohloka nokucindezeleka kwesampula yepulasitiki phakathi nenqubo yokuqina ngokusebenzisa amandla aqinile akhula kancane kancane, ukuze kutholwe uchungechunge lwemingcele yokusebenza ebalulekile.

Imishini yokuhlola ifilimu yepulasitiki isetshenziswa kabanzi ekulawuleni ikhwalithi yamabhizinisi okukhiqiza amafilimu epulasitiki ukusiza ukuqinisekisa ukuthi imikhiqizo ihlangabezana nezindinganiso ezifanele kanye nezidingo zamakhasimende. Ngesikhathi esifanayo, iphinde inikeze ukwesekwa kwedatha yomnyango wocwaningo nentuthuko ukuze uthuthukise ukusebenza komkhiqizo, okubaluleke kakhulu ukuthuthukisa ikhwalithi nokuncintisana kwemakethe yefilimu yepulasitiki.

Imishini yokuhlola amandla e-tensile isetshenziswa kabanzi ezintweni zensimbi, amapulasitiki, irabha, i-fiber, izinto eziyinhlanganisela neminye imikhakha. Ngezinto zensimbi, amandla ayo, ukuqina kanye ne-ductility kungaqondwa ngokuhlolwa; Ngemikhiqizo yepulasitiki, ukumelana nokuqina nokuqina kwayo kungahlolwa; Ngokuya ngefayibha nezinto eziyinhlanganisela, ingasiza ukucacisa izici zabo zemishini futhi inikeze isisekelo sokuklanywa komkhiqizo nokwenza kahle.

Ikholomu eyodwa isakhiwo esime mpo, idizayini ehlangene, ukonga isikhala, kuyilapho kuqinisekisa ukuzinza nokunemba kokuhlolwa. Umshini wokuhlola ufakwe izinzwa zokunemba okuphezulu kanye nezinhlelo zokulawula ezithuthukisiwe, ezingalinganisa ngokunembile imingcele yemishini yezinto zenjoloba nepulasitiki ngaphansi kwezimo ezihlukene zokucindezeleka ezifana nokwelula, ukucindezela nokugoba. Ifanele izinhlobonhlobo zenjoloba nepulasitiki, okuhlanganisa irabha, ipulasitiki, izinto eziyinhlanganisela, njll.

Umshini wokuhlola amandla enjoloba epulasitiki ikakhulukazi ngokusebenzisa ukungezwani kancane kancane kwento, ngenkathi ukala ukuwohloka kwezinto enqubweni yokuqina, ukuze kunqunywe amandla aqinile wento, ubude ngesikhathi sekhefu kanye nezinye izinkomba zokusebenza. Isimiso sayo sokusebenza sisekelwe eMthethweni kaHooke, othi ngaphakathi komkhawulo wokunwebeka, ingcindezi yento ilingana nengcindezi yayo.

Umshini wokuhlola ukunamathela kwe-raber nepulasitiki yokunamathela kuyithuluzi elibalulekile elisetshenziselwa ukuhlola ukunamathela kwenjoloba nezingubo zepulasitiki.
Izakhiwo zokunamathela zenjoloba nepulasitiki zibalulekile emikhakheni eminingi yezimboni. Umhloli ukala ngokunembile amandla esibopho phakathi kwento enamathelayo nesisekelo ngokulingisa izimo zokucindezeleka ezihlukahlukene ekusebenziseni kwangempela.
Ivamise ukusebenzisa ubuchwepheshe obuthuthukisiwe bokuzwela komshini kanye nezinhlelo zokulawula eziyinkimbinkimbi ukuze kufakwe imithwalo futhi kuqoshwe ngokunembile izinguquko kumanani wamandla ngesikhathi sokwelula. Ukusebenza komshini wokuhlola kulula, futhi opharetha angasetha imingcele efanele ngokwezidingo ezihlukene zokuhlola, njengejubane eliqinile, umthwalo omkhulu, njll.

Ngokuyinhloko isetshenziselwa ukukala izakhiwo zemishini zepulasitiki nezensimbi ngaphansi komthwalo oqinile. Isakhiwo sayo esiyisisekelo sihlanganisa i-fixture engaguquki kanye ne-fixture ephathekayo, futhi iziphetho ezimbili zesampula yezinto ezibonakalayo zigxilile ezintweni ezimbili ngokulandelana ngesikhathi sokuhlolwa. Ngezinto zensimbi, i-fixture idinga ukuba namandla anele okubamba ukuze kuqinisekiswe ukuthi isampuli ngeke ishelele phakathi nenqubo yokwelula, futhi ivumelane nezimo ezihlukahlukene (ezifana nezingxenye eziyindilinga, eziphambanayo ezinonxande, njll.) zesampula yensimbi; Okwezinto zepulasitiki, i-fixture kufanele iqinisekise kokubili ukugoqa futhi ayikwazi ukudala umonakalo oweqile we-extrusion kusampula.

Ithuluzi elinembayo elidizayinelwe ukuhlola amandla aqinile ephepha. Isakhiwo sonke sihlanganisa inkundla yokuhlola, isihluthulelo, isistimu yokulayisha kanye nesistimu yokulinganisa. Isiteji sokuhlola sinikeza ukusekelwa okuzinzile kwephepha, isihluthulelo sibambe ngokuqinile isampula lephepha ukuze livimbele ukuthi lingasheleli, uhlelo lokulayisha lusebenza ngokunembile amandla aqinile, futhi isistimu yokulinganisa iqapha amandla kanye nokuguqulwa ngesikhathi sangempela.

I-High And Low Temperature Universal Tensile Test Equipment ngokuvamile yakhiwa isistimu yokulawula, isistimu yokulawula izinga lokushisa, isistimu yokulayisha kanye nesistimu yokulinganisa. Uhlelo lokulawula lunesibopho sokusetha ngokunembile kanye nokulungisa imingcele yokuhlola efana nezinga lokushisa, isivinini esiqinile namandla okuqina. Isistimu yokulawula izinga lokushisa ingafinyelela ububanzi obubanzi bokulawula izinga lokushisa ukusuka ekushiseni okuphansi kuya phezulu, ukudala indawo edingekayo yokuhlola. Isistimu yokulayisha isebenzisa ukushuba okuzinzile nokulawulekayo ukuze kutholwe izinkomba ezibalulekile njengamandla okuqina namandla okukhiqiza ento. Uhlelo lokulinganisa lurekhoda ngokunembile ukuwohloka, ukucindezeleka kanye neminye imininingwane yezinto ngesikhathi sokuhlolwa Kusebenza emikhakheni eminingi.

Umhloli wamandla ocindezelayo umshini wokuhlola obalulekile osetshenziswa ngokukhethekile ukukala izakhiwo ezicindezelayo zezinto zokwakha. Idlala indima ebalulekile emikhakheni eminingi, njengesayensi yezinto ezibonakalayo, ukukhiqiza, ubunjiniyela bezokwakha, njll.

Isetshenziselwa ikakhulukazi ukuhlolwa okunembile kwamandla e-tensile nezinye izakhiwo zezinto ezihlukahlukene. Ngokusebenzisa amandla athile e-tensile, idatha ehlukahlukene njengamandla amakhulu okuqina, amandla okukhiqiza kanye ne-elastic modulus ingakalwa ngokunembile phakathi nenqubo yokuqina kwento.
Umshini wokuhlola unesistimu yokulawula ethuthukisiwe kanye nezinzwa ezinembile kakhulu ukuze kuqinisekiswe ukunemba nokuthembeka kwemiphumela yokuhlolwa.

Umshini wokuhlola ibhentshi lokucindezela i-tensile uyithuluzi lokuhlola impahla ebalulekile. Isetshenziselwa kakhulu ukuhlola izakhiwo zemishini yezinto ezihlukahlukene ezifana ne-tensile kanye nokucindezela.

Lo mshini wokuhlola unesistimu yokulinganisa enembile, engathola ngokunembile idatha ehlukahlukene ngesikhathi senqubo yokucindezeleka kwezinto ezibonakalayo, njengamandla okuqina, amandla okukhiqiza, i-modulus elastic, njll. Ukusebenza kwawo kulula, futhi ngemva kokuba imingcele isethwe uhlelo lokulawula, ukuhlolwa kungenziwa ngokuzenzakalelayo.

Lo mshini uklanyelwe ukwenza izivivinyo eziqinile ezintweni ezihlukahlukene. Ikala amandla kanye nokuguqulwa kwamasampuli ngaphansi kwemithwalo esetshenzisiwe. Ngamandla okulinganisa anembe, inikeza imiphumela enembayo yokulawula ikhwalithi nezinjongo zocwaningo ezinhlobonhlobo zezimboni.

Umshini wokuhlola amandla okuqina wekholomu eyodwa wezinto zepulasitiki uyisisetshenziswa esikhethekile esiklanyelwe ukukala ngokunembile amandla aqinile wezinto zepulasitiki. Ifaka ukwakheka kwekholomu eyodwa ukuze kube nokuzinza nokunemba. Ngobuchwepheshe obuphambili, inikeza imiphumela enokwethenjelwa yokulawulwa kwekhwalithi kanye nokubonakaliswa kwezinto ezibonakalayo embonini yepulasitiki. Lo mshini unikeza ukusebenza nokugcinwa kalula, okuwenza ube yithuluzi elibalulekile kubacwaningi nabakhiqizi ngokufanayo.
