D = vacuum pad SIZE (mm)
M =
Product Weight (kg) N = safety factor (2)
U = vacuum degre(kpa) S = Vacuum to pad
V = Vacuum volume (L)
D² =diameter of tube (cm)
L = length of tube (cm)
An example for vacuum system selection EX
Ex) If you want to hold and convey a 60 kg packing box within 0.3 sec. using 5 pads at a normal temperature, what kind of vacuum pad and pump model are suitable?
(Conditions the length of the air pipe = 3 m diameter of pipe = 6 mm vacuum degree = 60 Kpa )
* MB75 = Select one size bigger one than the theoretical size.
Vacuum pad volume MB75 = 110cm³ = 0.11 L X 5EA = 0.55 L
Vacuum pad volume + Vacuum pipe volume = Volume to become a vacuum from a vacuum pump through a vacuum pad
*Selection of the Vacuum pump model*
VMP10 = 0.64 L X 0.69’ = 0.44’
VMP20 = 0.64 L X 0.35’ = 0.22’ Pump selection = VMP 20 or VMP 30
VMP30 = 0.64 L X 0.26’ = 0.17’
