Turbodisk 2 - Operation

TURBINE SPEED
Turbine speed is determined by the drive air pressure
at the rotary atomizer and fluid flow rate.
Turbine speed can be closed loop controlled using
the fiber optic speed transmitter mounted at the back
of the turbine rotator assembly as a speed input to
remote speed controls such as the PulseTrack.
> The disk rotational speed determines
the quality of atomization and can be varied
for different flow rates and viscosities. For
optimum transfer efficiency and spray pattern
control, the disk rotational speed should be
set at the minimum required speed to achieve
proper atomization. Excessive speed reduces
transfer efficiency!
NOTE
W A R N I N G
> Do not exceed the maximum rated speed of
40,000 RPM for the 6 inch conical disk and 27,000
RPM for the 6 inch uni-disk.
!
W A R N I N G
> Never operate any disk atomizer in excess of
it's maximum rated speed ("K" number) as listed
in the service manual. Excessive speed may cause
the disk to disintegrate, causing serious damage
and/or injury.

Atomizers
-REFER TO FIGURE 5
All atomizers manufactured after April 6, 1982, bear
a “K” number. That number indicates the maximum
safe rotation speed for that series in tens of thousands.
For example:
9K = 9,000 RPM maximum safe speed,
40K = 40,000 RPM, etc.
If you have an atomizer that does not have a “K”
number, contact your Ransburg representative for
its maximum safe operating speed.
