Umbhobho wentsimbi othuthwayo: Isitshixo seziseko zophuhliso zamanzi ezithembekileyo kunye nendima yovavanyo lwempembelelo

Ipayipi yentsimbi ye-Ductile, edla ngokubizwa ngokuba yipayipi ye-ductile, yinxalenye ebalulekileyo yeziseko zamanzi zanamhlanje.Umbhobho wamanzi wentsimbi ethambileyoyeyona ndlela ilungileyo yokubonelela ngamanzi kamasipala, ulawulo lwamanzi amdaka, kunye neeprojekthi zothutho lwamanzi kwimizi-mveliso. Le mibhobho inokumelana okukhulu nempembelelo. Oku kubalulekile kuba ayifuni ukujongana nokungqubana ngexesha lokufakwa kunye nemithwalo engalindelekanga kuphela kodwa kunye nokungcangcazela ngexesha lokuthuthwa kunye neemeko ezinzima zendalo. Ukuqinisekisa ukuba isebenza kakuhle ixesha elide, kufuneka uvavanyo olungqongqo nolusemgangathweni.
Eyona ndlela iphambili yokujonga olu phawu lubalulekileyo luvavanyo lweCharpy impact. Luyimigangatho eyaziwayo kwihlabathi liphela, ilandela imithetho efana ne-ASTM A370 (evela e-US) okanye i-ISO 148 (yamazwe ngamazwe). Nantsi indlela esebenza ngayo: Okokuqala, iisampulu zisikwa ngononophelo ukusuka kwinyani.umbhobho we-ductileamacandelo. Emva koko, zenziwa zibe ziibha ze-10mm×10mm×55mm ezinee-notches ze-V okanye ze-U. Ezi bha zenziwe ukuze zifikelele kumaqondo obushushu athile. Kwiindawo ezibandayo-zemozulu, amaqondo obushushu adla ngokuba malunga ne-20°C, ngelixa kwiindawo ezishushu, malunga ne-20°C. Emva koko, i-pendulum elinganisiweyo iyakhululwa ukuze ibethe isampuli enee-notches. Amandla asetyenziswayo xa isampuli iphuka alinganiswa ngee-joules. Okukhona ixabiso lamandla liphezulu, kokukhona ukuxhathisa kwempembelelo yombhobho kungcono. Oku kuthetha ukuba umbhobho wamanzi wesinyithi othambileyo awuyi kwaphuka okanye ukusilela ngequbuliso phantsi koxinzelelo loomatshini.

Kubantu abafuna ukuthenga imibhobho yesinyithi ethambileyo, ukuqonda le nkqubo yovavanyo lwempembelelo kubaluleke kakhulu. Ibanceda ukuba bafumane ixabiso lombhobho wesinyithi ethambileyo baze babone ukuba ixabiso lawo lilungile na. Umgangatho ophezuluumbhobho wesinyithi othambileyoIqinisekiswe ngamaqela esithathu ngokuchasana kwayo nempembelelo ingabiza ngaphezulu kancinci. Kodwa ukuchitha imali engaphezulu ngoku kunokonga imali eninzi ekuhambeni kwexesha. Kungamisa ukugcinwa okubizayo, ukulungiswa okungxamisekileyo, kunye nexesha lokungasebenzi. Ababoneleli abalungileyo bahlala bevavanya iibhetshi zeepayipi rhoqo. Bakwanika amaxwebhu amaninzi, njengezatifikethi zovavanyo ezivela kwimibutho eyaziwayo efana ne-ANSI okanye i-BSI. La maxwebhu angqina ukuba iipayipi zabo ezithambileyo ziyahlangabezana okanye zingcono kunemigangatho yoshishino.
Xa utyala imali kwiziseko zophuhliso zamanzi ezibalulekileyo, ungalibali ukuba uvavanyo lokuxhathisa impembelelo lubaluleke kangakanani. Olu vavanyo luqinisekisa ukuba umbhobho wakho wesinyithi othambileyo uya kusebenza ngokuthembekileyo, ngokukhuselekileyo, nangokufanelekileyo amashumi eminyaka. Lunokunciphisa ukuvuza kwemibhobho kwaye lunciphise iindleko zizonke koomasipala nakubasebenzi bemizi-mveliso. Ngoko ke, soloko unika ingqalelo kolu vavanyo lubalulekileyo xa usenza isigqibo malunga nokuthenga imibhobho yesinyithi othambileyo. Ngale ndlela, unokuqinisekisa inkqubo yeziseko zophuhliso zamanzi ehlala ixesha elide nesebenzayo.
Ukuqukumbela, imibhobho yesinyithi ethambileyo ibalulekile kwiziseko zamanzi zanamhlanje. Uvavanyo lwempembelelo lweCharpy linyathelo elibalulekileyo ekuqinisekiseni umgangatho wazo. Ngokuqonda olu vavanyo, abathengi banokwenza izigqibo ezingcono malunga nokuthenga kwabo. Kwaye kwiziseko zamanzi ngokubanzi, uvavanyo olufanelekileyo lwempembelelo lubalulekile kwinkqubo ezinzileyo nenexabiso elifanelekileyo. Nokuba kukwiprojekthi yamanzi yedolophu encinci okanye kwisityalo esikhulu semizi-mveliso, ukuthembeka kwemibhobho yesinyithi ethambileyo kuxhomekeke kolu vavanyo lubalulekileyo.
