Kuyambitsa Vacuum System ya Ng’anjo ya Vacuum Sintering

Ma vacuum nthawi zambiri amakhala ndi mitundu yosiyanasiyana. Kusankhidwa kumatengera vacuum yomwe ikufunika panthawi yantchito. Ma vacuum odziwika bwino ndi awa:

(1) Dongosolo la vacuum yotsika: yokhala ndi mpope wamakina (pampu ya rotary vane pampu kapena pampu ya valve), mpweya womaliza ukhoza kufika pafupifupi 10 Pa;

(2) Dongosolo lapakatikati la vacuum: Lili ndi makina ophatikizika a Roots mpope ndi mpope wamakina (pampu ya rotary vane pampu kapena pampu ya slide valve), ndipo chopopera chomaliza chimatha kufikira 2 × 10-1 Pa;

(3) Dongosolo la vacuum lalitali: Nthawi zambiri amapangidwa ngati mpope wothirira + Mizu mpope + mpope wamakina (pampu ya rotary vane pampu kapena pampu ya slide valve), vacuum yomaliza imatha kufika 2 × 10-3 Pa;

(4) Ultra-high vacuum system: turbomolecular pump + Mizu mpope + makina mpope (rotary vane mpope kapena slide valve pampu), chomaliza vacuum digiri akhoza kufika 2 × 10-4 Pa.
