- Are all the connections on the atomizer set up properly?
- Are all connections tight?
- Observe the details on the pressure of the motor bearing air of the
turbine (see chapter “Operating Parameters”).
- Does the driving air of the turbine meet the requirements specified
in the operating parameters of these instructions?
In particular, the purity and dryness of the driving air is very
important for a trouble-free operation of the turbine.
- Can the bell disk be spun smoothly and easily by hand with motor
bearing air pressure applied?
- Is the bell disk correctly tightened on to the shaft?
- Are all high voltage components and the insulating components
connected correctly and do they comply with the applicable
regulations and standards?
The commissioning of an atomizer requires that the staff are fully
aware of safety regulations.
The staff must be trained on the atomizer. The information and
instructions in the operating instructions must be strictly adhered to.
If commissioning is being carried out because of work on the supply
lines of the atomizer, all related effects must be checked.
Be sure to follow the instructions of the high voltage generator and of
the components connected the high voltage.
Grounding, safe shut-off, and interlocks, among other things, are to be
thoroughly inspected and tested.
Carry out all checks and tests prescribed in the instructions before you
operate the atomizer.
The annex includes a check list for commissioning. The list contains
measurements and testing procedures required for a safe operation of
the equipment. Document all work carried out in the list.
At excessive speed, a firm grip of the bell disk on the shaft is not
guaranteed. A flying bell disk puts at risk life and limb.
Observe maximum rotational speed. The rotational speed must be
monitored.
Note the pressure of the braking air. If the pressure is above the
prescribed value, the bell disk can due to its inertia come loose from
the shaft while braking the turbine.
The pressure of the braking air must not exceed the "operating
parameters" indicated above.
