Oscillating Showers for Paper Machine Dryer Cylinder

The shower is one of the indispensable equipments of the paper machine, which is used in the processes of paper machine clothing cleaning, paper machine felt conditioning, paper web humidification, pulping or stripping, roller cleaning and spraying humidification.
The performance and characteristics of the spraying device have varying degrees of impact on paper quality, felt life, downtime, and cleaning consumption.
 

Turning the exterior handwheel of the manually operated version rotates the interior brush assembly. During the cleaning cycle, the brushes scrub the interior wall of the shower as well as each nozzle orifice. In seconds, accumulated debris is removed and discharged through the flush-out valve. This restores full liquid flow to the system without contaminating the sprayed surface.
 

Our motor/control package offers an economical way to eliminate the need for operator intervention to rotate the brushes. Retrofitting manual brush-type showers is fast and easy. In less than 10 minutes, the motor can be installed on the shower and the control unit mounted in a convenient location for operation. The unit can be set to clean at predetermined intervals, eliminating the need for any operator intervention. The unit can also be placed in manual mode, which enables the activation of individual brushes by an operator.

The smooth, controlled movement of cleaning showers across the felt from the Oscillator Shower Assembly ensures optimal felt cleaning with minimal water usage.  Users can easily and precisely control stroke and speed of the oscillator assembly. Settings can be stored or can be adjusted on- the-fly and alarm messages display if the controller detects any operational problems. Operating parameters can even be pre-programmed prior to delivery to further simplify set-up.
