Inkqubo yokuvavanya ubulukhuni beVickers

Imvelaphi kaVickers umvavanyi wobulukhuni

Ubunzima beVickers ngumgangatho wokumela ubunzima bezinto ezicetywayo nguRobert L. Smith kunye noGeorge E. Sandland ngo-1921 eVickers Ltd. Le yenye indlela yokuvavanya ubulukhuni obulandela ukuqina kwe-Rockwell kunye neendlela zokuvavanya ubulukhuni beBrinell.

Umgaqo weVickers umvavanyi wobulukhuni:

Umvavanyi wobulukhuni beVickers usebenzisa umthwalo we-49.03 ~ 980.7N ukucinezela idayimani ye-conical square ene-angle ehambelana ne-136 ° kumphezulu wezinto eziphathekayo.Emva kokubamba ixesha elichaziweyo, ixabiso lobulukhuni beVickers libalwa ngokulinganisa ubude be-diagonal ye-indentation kunye nokusebenzisa ifomula.

Uluhlu lwesicelo somthwalo kwezi ntlobo zintathu zilandelayo zeVickers (micro Vickers):

I-Vickers tester hardness enomthwalo we-49.03 ~ 980.7N ifanelekile ukulinganisa ubulukhuni beendawo zokusebenza ezinkulu kunye neengqimba ezinzulu zomhlaba.

Umthwalo ophantsi Ubunzima beVickers, umthwalo wokuvavanya<1.949.03N, ulungele ukulinganisa ubulukhuni bezinto zokusebenza ezincinci, izixhobo zokusebenza, okanye iingubo;

Ubulukhuni be-Micro Vickers, umthwalo wokuvavanya <1.961N, ilungele ukulinganisa ubulukhuni beefoyile zetsimbi kunye neengqimba zomphezulu ezinqabileyo kakhulu.

Ukongeza, ixhotyiswe nge-indenter ye-Knoop, inokulinganisa ubulukhuni be-Knoop bezinto ezinqabileyo neziqinileyo ezifana neglasi, iiseramics, i-agate, kunye namatye anqabileyo okwenziwa.

Izinto eziluncedo zeVickers tester hardness:

1. Uluhlu lokulinganisa lubanzi, ukusuka kwi-software yesinyithi ukuya kwiintsimbi ezinzima kakhulu, kwaye inokubonwa, ukusuka kumanani ambalwa ukuya kwamawaka amathathu eVickers ubunzima.

2. I-indentation incinci kwaye ayilonakalisi i-workpiece, engasetyenziselwa ukuvavanywa kobunzima kwii-workpieces ezingenakonakaliswa phezu kwendawo yokusebenza.

3. Ngenxa yovavanyo oluncinci lwamandla, amandla ovavanyo asezantsi anokufikelela kwi-10g, enokubona izixhobo zokusebenza ezincinci nezincinci.

Izinto ezingalunganga zeVickers tester hardness:

Xa kuthelekiswa neendlela zokuvavanya ubulukhuni beBrinell kunye neRockwell, uvavanyo lobulukhuni beVickers luneemfuno zokuguda komphezulu wesixhobo sokusebenza.Ezinye izixhobo zokusebenza zifuna ukupolishwa, nto leyo etya ixesha kwaye ifuna umsebenzi onzima

Abavavanyi bobulukhuni beVickers bachane ngokuthe ngqo kwaye abafanelanga ukusetyenziswa kwiindibano zocweyo okanye kwindawo, kwaye basetyenziswa kakhulu kwiilabhoratri.

Shandong Shancai Vickers uthotho lomvavanyi wobulukhuni (umfanekiso kaWang Songxin)

1. Economic Vickers umvavanyi ubulukhuni

2. Digital display kunye touch screen Vickers ubulukhuni tester

3. Umvavanyi wobulukhuni beVickers oluzenzekelayo ngokupheleleyo
