Richler vacuum pump blade rotating blade sliding blade scraping blade vc5075202303 high temperature blade Liqile vacuum pump blade rotary sliding blade scraper is a die-casting nickel aluminum alloy material, which is more durable than the blades of ordinary materials, resistant to high-strength impact, not easy to deformation, not bending, continuous cracking and cracking, corrosion resistance, high temperature resistance and other characteristics. Liqile vacuum pump blade rotary sliding blade scraper nickel aluminum alloy material is lighter than other metal materials, which is conducive to the blade being thrown out of the rotor and reducing resistance, Ensure the speed and flow pressure of the vacuum pump
