Enkambisweni yokuhlola ubulukhuni, amabhlogo obulukhuni ajwayelekile abalulekile. Ngakho-ke, iyini indima yamabhlogo obulukhuni, futhi ahlukaniswa kanjani?
I.Amabhulokhi obulukhuni adlala indima ezintathu kakhulu ekuhlolweni kobulukhuni: ukulinganisa abahloli bobulukhuni, ukuvumela ukuqhathanisa idatha, kanye nokuqeqesha opharetha.
1. Ngesikhathi sokusetshenziswa kwesikhathi eside kwesihloli sokuqina, kungase kwenzeke izinguquko ezinzwa zomshini noma esakhiweni somshini. Ngakho-ke, sisebenzisa amabhlogo ajwayelekile aphawulwe ngamanani aziwayo okuqina ukuqinisekisa noma ukulungisa ukunemba kwesihloli sokuqina. Ibhloko ngalinye lokuqina libhalwe ngenani lokuqina; ukuhlola ngebhloko yokuqina ngaphambi kokutholwa okusemthethweni kungalinganisa inani lesibonakaliso sesihloli sokuqina, kususe amaphutha ethuluzi, kuqinisekise ukuthi idatha yokulinganisa ihlangabezana nezidingo ezijwayelekile, kuqinisekise ukuzinza kokusebenza kwesihloli sokuqina, futhi kunqume ngokushesha ukuthi isihloli sokuqina sisesimweni esijwayelekile sokusebenza.
2. Ngokusebenzisa ukulinganisa amabhlogo obulukhuni anezincazelo ezihlanganisiwe, ukuqhathaniswa kwemiphumela yokuhlolwa kungatholakala phakathi kwabahloli bobulukhuni abahlukene nabahloli abahlukene. Ngokunikeza izinkomba ezijwayelekile ezinamanani obulukhuni aziwayo, amazinga okuhlola ngaphansi kwabahloli bobulukhuni abahlukene kanye nezimo zokulinganisa ezahlukene ayahlanganiswa.
3. Amabhulokhi obulukhuni obujwayelekile nawo avame ukusetshenziswa ekuqeqeshweni kwabasebenzi ezindaweni zokucwaninga noma ezimbonini ukuthuthukisa ikhono lokusebenza.
Amanani abo obulukhuni alinganiswa yizikhungo ezigunyaziwe, ezibonisa ukulandeleka, ukunemba, kanye nokuqina. Izinto ezisetshenziswayo zamabhulokhi obulukhuni zifana nezomsebenzi ozohlolwa (njengensimbi, ipulasitiki, njll.), ezingahambisana nezindlela ezahlukene zokulinganisa ubulukhuni (Brinell, Rockwell, Vickers, njll.).
II.Ukuhlukaniswa kwamabhulokhi obulukhuni kusekelwe kakhulu ezikalini ezahlukene zobulukhuni, izinhlobo zezinto ezibonakalayo, kanye nobubanzi bamanani obulukhuni. Izinhlobo ezivamile yilezi ezilandelayo:
1. Ukuhlukaniswa Ngendlela Yokulinganisa Ubulukhuni
Lena indlela yokuhlukanisa evame ukusetshenziswa kakhulu, ehambisana nezinhlobo zokuhlola ubulukhuni ezijwayelekile:
Amabhulokhi Okuqina Kwe-Rockwell (HRC, HRB, njll.): Iyahambisana nabahloli bokuqina kwe-Rockwell, esetshenziselwa ukuhlolwa kokuqina kwezinto zensimbi okuvamile.
Amabhulokhi Okuqina Kwe-Brinell (HBW): Iyahambisana nabahloli bokuqina kwe-Brinell, efanelekile ukulinganisa izinsimbi ezinobunzima obuphansi noma izinto ezinezinhlamvu eziqinile.
Amabhulokhi Okuqina Kwe-Vickers (HV): Iyahambisana nabahloli bokuqina kwe-Vickers, enezici ezinembile kakhulu, futhi ingalinganisa izinto zokusebenza ezincane, izingxenye ezincane, kanye nezendlalelo eziqinile ebusweni.
Amabhulokhi Okuqina Kogugu (HS): Ahambisana nabahloli bokuqina kogugugu, asetshenziswa kakhulu ekuhlolweni kokuqina kwezinto zokusebenza ezinkulu noma imishini engashukumi.
Amabhulokhi Okuqina Kwe-Leeb (HL): Iyahambisana nabahloli bokuqina kwe-Leeb, efanelekile ezimweni zokuhlola ezisendaweni kanye nezingonakalisi.
2. Ukuhlukaniswa Ngokwezinto Ezibalulekile
Amabhulokhi Okuqina Kwensimbi: Kufaka phakathi insimbi yekhabhoni, insimbi ye-alloy, insimbi engagqwali, i-alloy yethusi, njll., ehlanganisa izidingo zokuhlolwa kwezingxenye eziningi zensimbi zezimboni.
Amabhulokhi Okuqina Angewona insimbi: Njengezibhulokhi zokuqina zepulasitiki, zerabha, kanye neze-ceramic, ezihambisana nokulinganisa ubulukhuni bezinto ezingezona insimbi.
3. Ukuhlukaniswa Ngokwezinga Lokunemba
Ibanga Elijwayelekile (Ibanga 1): Lisetshenziselwa ukulinganisa abahloli bobulukhuni, ngokunemba okuphezulu kwezinombolo kanye nokulandelela amazinga kazwelonke okumetrological.
Ibanga Lokusebenza (Ibanga 2): Lisetshenziselwa ukuqhathanisa ukuhlolwa kwansuku zonke nokuqinisekisa ukuzinza kwethuluzi, ukuhlangabezana nezidingo zokuhlolwa kokukhiqiza okuvamile.
Uma uthenga amabhlogo obulukhuni, kuyadingeka ukufanisa uhlobo lomhloli wobulukhuni, ububanzi bobulukhuni bento yokusebenza okufanele ihlolwe, kanye nezidingo zokunemba. Ukulinganisa kufanele kulandele izimiso "zezindinganiso ezifanayo, izimo ezifanayo, kanye nokusebenza okujwayelekile" ukuqinisekisa ukunemba kanye nokulandeleka kwamanani alinganisiwe.
