Spray cleaning is used in all industrial fields.
Spray cleaning is usually performed using an aqueous cleaning medium, typically an alkaline cleaner. The medium is sprayed onto the surface to be cleaned through nozzles at high pressure – with standard cleaning the working pressure is generally around 6 to 8 bar, with targeted cleaning between 20 and 25 bar. Soiling is then partially removed or emulsified by the chemical effect of the medium and partially sprayed off by the high kinetic energy of the jet.
The shape and arrangement of the nozzles and the spray force have a decisive influence on the quality of the cleaning here. To ensure even cleaning of all component surfaces, it may be necessary to move the product being washed and/or the nozzles. This is often done using a rotary wheel.
For spray cleaning in automated large-volume production lines, the workpiece is generally advanced using appropriate transport systems and walking beams.
