Turbodisk 2 - Operation

16

OPERATION

As with any spray finishing system, operation of the

Turbodisk 2 involves properly setting the operating

parameters to obtain the best finish quality for the

coating material being sprayed, while maintaining

correct operation and reliability of the equipment

used. Adjustments to operating parameters,

which cover spraying, cleaning and on/off control,

include:

• Fluid Type

• Fluid Flow Rate

• Turbine Speed

• Electrostatic Voltage

• Target Distance

COATING MATERIALS

The Turbodisk 2 can be used with a broad range

of coating material conductivities. However, with

waterborne paints, it may be necessary to isolate the

paint supply from ground.

W A R N I N G

>

Operators must be fully trained in safe

operation of electrostatic equipment. Operators

must read all instructions and safety precautions

prior to using this equipment (See NFPA 33,

Chapter 16).

!

W A R N I N G

>

Isolated fluid supplies using either waterborne

or highly conductive solvent base coatings can

produce hazardous high voltage discharges

which can cause fires or injury to personnel.

FLUID FLOW CONTROL

-REFER TO FIGURES 19-22

Fluid flow control is dependent on the valve

configuration of the Turbodisk 2. If the Turbodisk 2

is configured with no valves or a 3-way valve, fluid

flow is controlled externally at the paint source. If the

Turbodisk 2 is equipped with a regulator, fluid flow

can be controlled via the air pilot signal. The high

flow and low flow regulators each have procedures

on how to control and deliver consistent fluid flows.

For more information on controlling the fluid delivery

using regulators, refer to that specific manual which

is included with the system.

To check fluid flow rates, the disk must be removed.

See the maintenance section for removal procedure.

The fluid can then be manually triggered to measure

actual flow in a graduated beaker over a specified

time period.

W A R N I N G

>

Danger of shock and/or personal injury can

occur. Proper grounding procedures, which are

outlined in the Ransburg safety bulletins, must

be followed. Personnel must never work near or

perform work on the turbine when the turbine

is spinning or when high voltage is on.

!

>

Fluids and lubricants used in this system

must contain NO silicones!

>

Do NOT operate the unit without an atomizer

disk! Without a disk, overspeed, resulting in

premature bearing failure, is possible.

>

The air supplied to the motor must be dry,

clean and free of oil or moisture. The atmospheric

dew point should be 10

o

F or less. The air heater

used should be adjusted only high enough to

prevent condensation from forming on the motor

housing or at the exhaust port.
