Ukuhlolwa kokuqina kweBrinell kwasungulwa unjiniyela waseSweden uJohan August Brinell ngo-1900 futhi kwaqala ukusetshenziswa ukukala ubulukhuni bensimbi.
(1)HB10/3000
① Indlela yokuhlola nomgomo: Ibhola lensimbi elinobubanzi obungu-10 mm licindezelwa endaweni ebonakalayo ngaphansi komthwalo ongu-3000 kg, futhi ububanzi bokuhlehlisa bulinganiswa ukuze kubalwe inani lokuqina.
②Izinhlobo zezinto ezisebenzayo: Ifanele izinto zensimbi eziqinile njengensimbi ekhonjiwe, insimbi eqinile, ama-alloys asindayo, njll.
③Izimo zohlelo lokusebenza ezijwayelekile: Ukuhlolwa kokubalulekile kwemishini esindayo nezisetshenziswa. Ukuhlolwa kokuqina kwama-castings amakhulu nama-forging. Ukulawulwa kwekhwalithi kwezobunjiniyela nokukhiqiza.
④Izici nezinzuzo: Umthwalo omkhulu: Ifanele izinto eziwugqinsi futhi eziqinile, ingamelana nokucindezela okukhulu, futhi iqinisekise imiphumela yokulinganisa enembile. Ukuqina: I-indenter yebhola yensimbi inokuqina okuphezulu futhi ifanele ukusetshenziswa kwesikhathi eside nokuphindaphindiwe. Uhlu olubanzi lwezinhlelo zokusebenza: Iyakwazi ukuhlola izinhlobonhlobo zezinto eziqinile zensimbi.
⑤Amanothi noma imikhawulo: Usayizi wesampuli: Isampula enkulu iyadingeka ukuze kuqinisekiswe ukuthi ukuhlehlisa kukhulu ngokwanele futhi kunembile, futhi ingaphezulu lesampula kufanele libe flat futhi lihlanzeke. Izidingo ezingaphezulu: Indawo engaphezulu idinga ukushelela futhi ingabi nakungcola ukuze kuqinisekiswe ukunemba kwesilinganiso. Ukugcinwa kwezisetshenziswa: Izinto zokusebenza zidinga ukulinganiswa futhi zigcinwe njalo ukuze kuqinisekiswe ukunemba nokuphindaphinda kokuhlolwa.
(2)HB5/750
①Indlela yokuhlola nomgomo: Sebenzisa ibhola lensimbi elinobubanzi obungu-5 mm ukuze ucindezele endaweni ebonakalayo ngaphansi komthwalo ongu-750 kg, futhi ulinganise ububanzi bokuhlehlisa ukuze ubale inani lokuqina.
②Izinhlobo zezinto ezisebenzayo: Isebenza ezintweni zensimbi ezinobulukhuni obumaphakathi, njengama-alloys ethusi, ama-alloys e-aluminium, nensimbi yobulukhuni obumaphakathi. ③ Izimo zohlelo lokusebenza ezijwayelekile: Ukulawulwa kwekhwalithi yezinto zensimbi ezinobulukhuni obumaphakathi. Ucwaningo nokuthuthukiswa kwezinto kanye nokuhlolwa kwelabhorethri. Ukuhlolwa kokuqina kwempahla ngesikhathi sokukhiqiza nokucubungula. ④ Izici nezinzuzo: Umthwalo omaphakathi: Isebenza ezintweni ezinobulukhuni obumaphakathi futhi ingakala ubulukhuni bazo ngokunembile. Isicelo esivumelana nezimo: Kusebenza ezintweni ezihlukahlukene zobulukhuni obuphakathi nokuvumelana nezimo okuqinile. Ukuphindaphinda okuphezulu: Ihlinzeka ngemiphumela yokulinganisa ezinzile futhi engaguquki.
⑥Amanothi noma imikhawulo: Ukulungiswa kwesampula: Indawo yesampula idinga ukuba isicaba futhi ihlanzeke ukuze kuqinisekiswe ukunemba kwemiphumela yokulinganisa. Imikhawulo yezinto ezibonakalayo: Ngezinto ezithambile kakhulu noma eziqine kakhulu, ezinye izindlela zokuhlola ubulukhuni ezifanele zingadinga ukuba zikhethwe. Ukugcinwa kwezisetshenziswa: Izinto zokusebenza zidinga ukulinganiswa futhi zigcinwe njalo ukuze kuqinisekiswe ukunemba nokwethembeka kwesilinganiso.
(3)HB2.5/187.5
①Indlela yokuhlola nomgomo: Sebenzisa ibhola lensimbi elinobubanzi obungu-2.5 mm ukuze ucindezele endaweni ebonakalayo ngaphansi komthwalo ongu-187.5 kg, futhi ulinganise ububanzi bokuhlehlisa ukuze ubale inani lokuqina.
②Izinhlobo zezinto ezisebenzayo: Isebenza ezintweni zensimbi ezithambile kanye nama-alloys athambile, njenge-aluminium, ingxubevange yomthofu, nensimbi ethambile.
③Izimo zohlelo lokusebenza ezijwayelekile: Ukulawulwa kwekhwalithi yezinto ezithambile zensimbi. Ukuhlolwa kwezinto ezibonakalayo ezimbonini zikagesi nezikagesi. Ukuhlolwa kokuqina kwezinto ezithambile ngesikhathi sokukhiqiza nokucubungula.
④Izici nezinzuzo: Umthwalo ophansi: Isebenza ezintweni ezithambile ukugwema ukuhlehlisa ngokweqile. Ukuphindaphinda okuphezulu: Ihlinzeka ngemiphumela yokulinganisa ezinzile futhi engaguquki. Uhlu olubanzi lwezinhlelo zokusebenza: Iyakwazi ukuhlola izinhlobonhlobo zezinto zensimbi ezithambile.
⑤ Amanothi noma imikhawulo: Ukulungiswa kwesampula: Indawo yesampula idinga ukuba isicaba futhi ihlanzeke ukuze kuqinisekiswe ukunemba kwemiphumela yokulinganisa. Imikhawulo yezinto ezibonakalayo: Ngezinto eziqinile kakhulu, kungase kudingeke ukhethe ezinye izindlela zokuhlola ubulukhuni ezifanele. Ukugcinwa kwezisetshenziswa: Izisetshenziswa zidinga ukulinganiswa futhi zigcinwe njalo ukuze kuqinisekiswe ukunemba nokwethembeka kwesilinganiso.
