Suction - Import export

How does vacuum handling work? Vacuum handling using suction cups is simple. A pump sucks in the vacuum between the suction cup and the part to be lifted, and stores this vacuum in a chamber dedicated for this purpose. By creating a vacuum, the atmospheric pressure is eliminated in the suction cup enclosure. The product is then pressed against the suction cup by this same atmospheric pressure of 1 kg/cm² (which varies from 950 to 1030 hectopascals); consequently, on a suction cup of 1 m² there is a pressure of 10,000 kg, making it capable of raising this same load. This physical phenomenon makes handling by suction cups an extremely efficient and reliable technique, capable of performing a very large number of handling operations.
