Chiyambi cha Vickers hardness tester

Vickers kuuma ndi muyezo woyimira kuuma kwa zinthu zomwe Robert L. Smith ndi George E. Sandland mu 1921 ku Vickers Ltd. Iyi ndi njira ina yoyesera kuuma kutsata njira zoyesera za Rockwell hardness ndi Brinell.

Mfundo ya Vickers hardness tester:

The Vickers hardness tester imagwiritsa ntchito katundu wa 49.03 ~ 980.7N kukanikizira diamondi yayikulu yokhala ndi ngodya ya 136 ° pamwamba pa zinthuzo.Pambuyo poigwira kwa nthawi yotchulidwa, mtengo wa Vickers wouma umawerengedwa poyesa kutalika kwa diagonal ya indentation ndikugwiritsa ntchito ndondomekoyi.

Katundu wogwiritsa ntchito mitundu itatu iyi ya Vickers (micro Vickers):

The Vickers hardness tester yokhala ndi katundu wa 49.03 ~ 980.7N ndiyoyenera kuyeza kuuma kwa zida zazikulu zogwirira ntchito ndi zigawo zakuya pamwamba.

Low katundu Vickers kuuma, mayeso katundu<1.949.03N, oyenera muyeso kuuma kwa workpieces woonda, zida pamwamba, kapena zokutira;

Kuuma kwa Micro Vickers, kuyesa kulemera <1.961N, koyenera kuyeza kuuma kwazitsulo zazitsulo ndi zigawo zoonda kwambiri.

Kuphatikiza apo, yokhala ndi Knoop indenter, imatha kuyeza kuuma kwa Knoop kwa zinthu zosalimba komanso zolimba monga magalasi, zoumba, agate, ndi miyala yamtengo wapatali.

Ubwino wa Vickers hardness tester:

1. Miyezo yoyezera ndi yotakata, kuchokera kuzitsulo zamapulogalamu kupita kuzitsulo zolimba kwambiri, ndipo zimatha kudziwika, kuchokera ku zochepa mpaka zikwi zitatu za kuuma kwa Vickers.

2. Indentation ndi yaying'ono ndipo sikuwononga workpiece, yomwe ingagwiritsidwe ntchito poyesa kuuma pazitsulo zomwe sizingawonongeke pamtunda wa workpiece.

3. Chifukwa cha mphamvu yake yaying'ono yoyesera, mphamvu yochepa yoyesera imatha kufika 10g, yomwe imatha kuzindikira zida zoonda komanso zazing'ono.

Kuipa kwa Vickers hardness tester:

Poyerekeza ndi njira zoyezera kuuma kwa Brinell ndi Rockwell, kuyesa kwa kuuma kwa Vickers kuli ndi zofunikira pakusalala kwa pamwamba pa chogwirira ntchito.Zopangira zina zimafuna kupukuta, zomwe zimawononga nthawi komanso zogwira ntchito

Ma Vickers hardness testers ndi olondola kwambiri ndipo sali oyenera kugwiritsidwa ntchito pamisonkhano kapena pamalo, ndipo amagwiritsidwa ntchito kwambiri m'ma laboratories.

Shandong Shancai Vickers kuuma woyesa mndandanda (chithunzi cha Wang Songxin)

1. Economic Vickers kuuma woyesa

2. Digital chiwonetsero ndi kukhudza chophimba Vickers kuuma tester

3. Mokwanira basi Vickers kuuma woyesa
