VACUUM CONVEYORS

Disconnecting the compressed-air pipeline
Before the compressed-air pipe of the pump is discon-
nected the pressure to the compressor must be turned
off. After that, the pipeline may be disconnected.
Dismounting the conveyor
It important that the conveyor is emptied of its powder
before dismounting is started. The compressed-air
supply must be disconnected before dismounting the
conveyor.
Mounting of the conveyor
The conveyor is delivered mounted. When mounting it
after cleaning/servicing, it is important that seals and
filters are mounted correctly so that leakage does not
occur. C21 and C33 shall be anchored at one point at
least (either at the bottom valve unit or at the connec-
tion girdle). C56 shall be anchored at two points at
least (at the bottom valve unit and at the upper or low-
er connection bracket).
Hot surfaces
There is a risk that the external air shock becomes hot
(60° C, 140° F) during and after use.
Position of the operator
The operator shall be at a position where he can easily
start and stop the conveyor.
Remote control of the conveyor
When using remote control, the system builder should
ensure that the conveyor can not be simultaneously
operated from two locations.
Installation of the conveying pipeline
Correct dimensioning and installation is A and O for the
system to work in the best possible way.
Please contact your local PIAB distributor as to dimen-
sioning of the diameters of the pipes, their length,
number of bends and possible option of injection units
or pipe emptying function. It is important that the pipe-
line system is sealed in order to prevent the conveyed
powder from leaking from the equipment to cause
damage to other devices and injuries. It is also impor-
tant to make sure that no foreign matters can inadvert-
ently be sucked into the conveyor.
Some basic tips
X
The conveying pipeline should be installed without
having any unnecessary bends.
X
Avoid inclined rises in the conveying pipeline.
X
The radius of the pipeline should be at least 10
times the pipe diameter.
X
Choose pipes instead of hoses where possible.
X
Avoid all types of edges and restrictions at pipe
joints and connections.
Noise level
The measured noise levels (72–76 dBa) have been
measured in the following manner. The distance be-
tween the pump and sound level meter = 1 metre. The
higher measuring value applies to the exhaust air-flow
in the direction of the sound level meter and the lower
measuring value applies to the exhaust air flowing
from the sound level meter. Please notice that the
noise level of the conveying depends on the kind of
powder that is conveyed.
