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 2.

Atomizers

(Refer to "Typical Maximum Safe

Operating Speeds")

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 ITW Ransburg repre-sentative

for its maximum safe operating speed.

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 pat-

tern control, the disk rotational speed should

be set at the minimum required speed to

achieve proper atomization.

Excessive speed reduces transfer efficiency!

NOTE

>

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.

This maximum speed includes speed over-

shoot when fluid delivery is stopped. Dam-

age to persons or equipment may result in

over-speed conditions.

Never operate any disk atomizer in

excess of it's maximum rated speed ("K"

number) as listed in the service manual. Ex-

cessive speed may cause the disk to disinte-

grate, causing serious damage and/or injury.

Inspect disk platter daily for wear or

damage. Replace if excessively worn or

damaged. Worn or damaged disk platters

can cause an imbalanced condition and

shorten bearing life. Warranty will be voided

if damaged disks are used.
