Taw qhia ntawm Lub Tshuab Nqus Tsev ntawm Nqus Sintering Rauv

Lub tshuab nqus tsev feem ntau muaj ntau yam kev sib txuas. Kev xaiv yog ua raws li lub tshuab nqus tsev xav tau thaum ua haujlwm. Common lub tshuab nqus tsev vacuum yog raws li nram no:

(1) Lub tshuab nqus tsev qis: nruab nrog lub tshuab nqus tsev twj (rotary vane twj lossis swb valve), lub tshuab nqus tsev qhov kawg tuaj yeem ncav cuag li 10 Pa;

(2) Lub tshuab nqus tsev nruab nrab: Nws yog nruab nrog kev sib xyaw ntawm cov hauv paus twj tso kua mis thiab tshuab twj tso kua mis (rotary vane twj lossis swb valve twj), thiab lub tshuab nqus tsev qhov kawg tuaj yeem ncav cuag 2 × 10-1 Pa;

(3) Lub tshuab nqus tsev siab: feem ntau configured li diffusion twj + Roots twj + mechanical twj (rotary vane twj los yog swb valve twj), lub tshuab nqus tsev qhov kawg tuaj yeem ncav cuag 2 × 10-3 Pa;

(4) Ultra-high lub tshuab nqus tsev: turbomolecular twj tso kua mis + Lub hauv paus twj tso kua mis + mechanical twj (rotary vane twj los yog swb valve twj), qhov kawg nqus tsev kawm ntawv qib siab tuaj yeem ncav cuag 2 × 10-4 Pa.
