Ransburg Overhead Electric Reciprocator ER-8100 - Manual (Page 38)

The following calculations can be used to deter-
mine the minimum loop radius, throat openings,
booth and reciprocator heights, and booth dfm
requirements for a disk installation.
Conveyor Data
A = Largest part dimension (rotating or
indexing diameter)
W 2 + D 2 = A
C = Disk Diameter
>
The normal disk diameter on a new in-
stallation will be 6-inch. However, substitute
the appropriate diameter when required.
NOTE
R = Minimum Conveyor Loop Radius
D = Conveyor Loop Diameter
T = Standard Conveyor Throat
Opening
T (1) = Conveyor Throat Opening for a
Highly Conductive or Waterborne
System
Conveyor Loop Diameter
(see Figure 16)
Formula:
(A + 2) + (C + 2) + 12” (Ideal Target Distance) = R
R X 2 = D
Reciprocator Data
Reciprocator Stroke Length (RL)
(see Figure 17)
Formula :
RL = Part Height + 12-inch (minimum 8-inch
overstroke at top and 4-inch overstroke at bottom)
Reciprocator Mounting
(see Figure17)
45 3/4-inch = Length of disk, rotator, extension,
and insulator
20-inch (Ref) = Minimum clearance to the floor
Formula:
20-inch (Ref) + RL + 45 3/4-inch = Distance from
the floor to the reciprocator mounting support
>
All dimensions are in inches.
NOTE
Conveyor Throat Opening
(see Figure 16)
Formula:
A = 14-inch * = T
A + 20-inch * = T (1)
* Substitue 4-6-inch when a hose containment
system is used. The 20-inch requirement for
highly conductive or waterborne system DOES
NOT apply for hose containment systems.
>
Reciprocator lengths available are 2-32
feet in 1 foot increments. Always round up
to the next highest foot increment to de-
termine proper reciprocator length. Adjust
overstroke dimensions (maintain minimum)
to compensate for excess length.
Example:
63-inch Part Height + 12-inch (total over-
stroke) = 75-inches
75-inch Stroke Requirement = 84-inch (7
ft.) Reciprocator
