Working principle of vacuum generator

A vacuum generator is a new, efficient, clean, economical, small vacuum component that uses a positive pressure source to generate negative pressure, which makes it very easy and convenient to obtain negative pressure in places with compressed air or in places where positive and negative pressure are required in a pneumatic system. Vacuum generators are widely used in industrial automation, machinery, electronics, packaging, printing, plastics and robots. The traditional use of vacuum generators is to cooperate with vacuum suction cups to adsorb and transport various materials, especially suitable for adsorbing fragile, soft and thin non-ferrous, non-metallic materials or spherical objects. In such applications, a common feature is that the required air extraction volume is small, the vacuum requirement is low and intermittent operation. The author believes that the analysis and study of the suction mechanism of the vacuum generator and the factors affecting its working performance hav
