The Wagner Tips & Tricks: Standard application values
By: Martin Krössing, Manager WAGNER Applications Technology
||In my capacity as manager of the Applications Technology Department at WAGNER, I have visited customers all over the world. In this column, I would like to tell you about the most frequent problems I have been confronted with and - more particularly - about the solutions to these. Just take a regular look; it will definitely be worthwhile.|
The gun performance describes the area
which a spray gun can coat in one minute.
This is how the gun performance is calculated:
Powder Output Measurement
This measurement is of interest if you want to find out how the wear
on wearing parts affects the powder consumption, or whether the individual guns
deliver an equal amount of powder at the same setting. In order to measure the
powder output an empty powder measuring bag is weighed and fixed to the gun.
Then powder is sprayed through the gun for precisely one minute. At the end
the powder bag is weighed.
Fan spray nozzle
| The Fan spray nozzle is widely used in modern
coating plant. The reason for this is the more uniform coating and the
greater effective depth.
| Deflector cone
| Deflector cones tend to generate a picture frame
affect. The smaller the deflector plate the less critical is this effect.
| Wide fan spray nozzle
| This nozzle system, also known colloquially
as a duck's bill, is used for larger outputs of powder due to its geometry.
