Vacuum system calculations General input
Vacuum systems for material handling can be decentralized or centralized. A decentralized vacuum system is designed so that each suction cup has a dedicated, independent vacuum source. A centralized vacuum system is designed to have one vacuum source for multiple suction cups. Handling sheet metal is an example of a sealed system and handling cardboard is an example of a leaking system.
The examples are calculated using the following general assumptions:
Initial flow required are for the sealed system examples is 0.7 Nl/s per suction cup FC75P, and the corresponding value is 1.2 Nl/s for the leaking system examples using the suction cup BX75P. CO2-emission, world index: 0.019 kg CO2 per produced m3 of compressed air and 0.19 kg CO2 per kWh. Machine operating hours per year: 3.000 h.
