Fampidirana ny Vacuum System of Vacuum Sintering Lafaoro

Ny rafitra banga amin’ny ankapobeny dia manana fitambarana isan-karazany. Ny fifantenana dia mifototra amin’ny banga ilaina mandritra ny asa. Ny rafitra vacuum mahazatra dia toy izao manaraka izao:

(1) Low vacuum rafitra: fitaovana amin’ny mekanika paompy (rotary vane paompy na slide valva paompy), ny farany banga mety hahatratra 10 Pa;

(2) Medium vacuum rafitra: Izy io dia fitaovana miaraka amin’ny fitambaran’ny Roots paompy sy mekanika paompy (rotary vane paompy na slide valve paompy), ary ny farany banga mety hahatratra 2 × 10-1 Pa;

(3) High vacuum rafitra: Amin’ny ankapobeny voaendrika ho diffusion paompy + Roots paompy + mekanika paompy (rotary vane paompy na slide valve paompy), ny farany banga mety hahatratra 2 × 10-3 Pa;

(4) Ultra-high vacuum rafitra: turbomolecular paompy + Roots paompy + mekanika paompy (rotary vane paompy na slide valva paompy), ny farany banga ambaratonga mety hahatratra 2 × 10-4 Pa.
