Umsuka we-Vickers umhloli wokuqina
Ukuqina kwe-Vickers kuyindinganiso yokumela ubulukhuni bempahla eyahlongozwa ngu-Robert L. Smith no-George E. Sandland ngo-1921 e-Vickers Ltd. Lena enye indlela yokuhlola ubulukhuni elandela izindlela zokuhlola ubulukhuni be-Rockwell kanye ne-Brinell.
Isimiso se-Vickers tester hardness:
Umhloli wokuqina we-Vickers usebenzisa umthwalo ongu-49.03~980.7N ukuze ucindezele idayimane eliyindilinga eliyisikwele eline-engeli ehlobene engu-136 ° ebusweni bento.Ngemva kokuyibamba isikhathi esishiwo, inani lobulukhuni be-Vickers libalwa ngokulinganisa ubude be-diagonal bokuhlehlisa nokusebenzisa ifomula.
Ibanga lesicelo sokulayisha lezinhlobo ezintathu ezilandelayo zamaVickers (amaVickers amancane):
Isihloli sokuqina se-Vickers esinomthwalo ongu-49.03~980.7N sifaneleka ukukalwa kokuqina kwezinto zokusebenza ezinkulu nezendlalelo ezijulile zendawo.
Ubulukhuni be-Vickers obuphansi, umthwalo wokuhlola<1.949.03N, ofanele ukukalwa kokuqina kwezinto zokusebenza ezizacile, indawo yamathuluzi, noma okokunamathela;
Ubulukhuni be-Micro Vickers, umthwalo wokuhlola<1.961N, ofanele ukukalwa kokuqina kwamafoyili ensimbi kanye nezingqimba zangaphezulu ezizacile kakhulu.
Ngaphezu kwalokho, ifakwe i-indenter ye-Knoop, ingakala ubulukhuni be-Knoop bezinto eziphukayo neziqinile njengengilazi, izitsha zobumba, i-agate, namatshe ayigugu okwenziwa.
Izinzuzo ze-Vickers tester hardness:
1. Ibanga lokulinganisa libanzi, kusukela ezinsimbi zesofthiwe kuya kwezinsimbi eziqinile, futhi zingatholwa, kusukela kumanani ambalwa wokuqina we-Vickers ayizinkulungwane ezintathu.
2. I-indentation incane futhi ayilimazi i-workpiece, engasetshenziselwa ukuhlolwa kokuqina kuma-workpieces angenakonakala ebusweni bomsebenzi.
3. Ngenxa yamandla ayo amancane okuhlola, amandla amancane okuhlola angafinyelela ku-10g, angakwazi ukubona izingcezu zokusebenza ezincane nezincane.
Ububi be-Vickers tester hardness:
Uma kuqhathaniswa nezindlela zokuhlola ubulukhuni be-Brinell ne-Rockwell, ukuhlolwa kokuqina kwe-Vickers kunezidingo zokushelela kwendawo yokusebenza.Ezinye izinto zokusebenza zidinga ukupholishwa, okudla isikhathi futhi okusebenza kanzima
Abahloli bokuqina be-Vickers banembe ngokuqhathaniswa futhi abakulungele ukusetshenziswa kuma-workshops noma esizeni, futhi basetshenziswa kakhulu kumalabhorethri.
Uchungechunge lomhloli wokuqina we-Shandong Shancai Vickers (isithombe sika-Wang Songxin)
1. Umhloli wobulukhuni be-Economic Vickers
2. Isibonisi sedijithali nesihloli sokuqina sokuqina kwesikrini esithi Vickers
3. Umhloli wobulukhuni we-Vickers ozenzakalelayo ngokugcwele
