Start-up and operation
Preparation for start-up
Basic conditions
By the start-up of the OptiSpray DPP01 Dense phase pump, the following
basic conditions, which have an influence on the powder transport, must
be considered:
-
Characteristic of hose layout (suction hose)
-
Length and height difference of the suction distance - max. 3 m
-
Length of the conveying distance - min. 10 m
-
Powder preparation and powder quality
-
Spatial arrangement of the OptiSpray DPP01 Dense phase
pump (layout, length and internal diameter of the suction
hose)
Basic information
The adherence of the following principles leads to a successful start-up of
the OptiSpray DPP01 Dense phase pump:
-
The suction distance is to be kept as short as possible
-
If the powder hose can be arranged wavy in plump line, then
this is to be preferred to the horizontal arrangement (flat on
the floor)
-
At the suction area, a homogeneous fluidization must be en-
sured, so that no air ducts (craters) can be formed
-
Basically, the powder transport with the OptiSpray DPP01
Dense phase pump works with every powder type, which can
be fluidized. If the powder is for example humid or contami-
nated with other materials, then the conveying can be nega-
tively influenced or does not work at all
-
The OptiSpray DPP01 Dense phase pump has to be in-
stalled vertically
