The water jet pipe is mounted on the paper machine frame for cleaning the roller surface, and the inside of the roll leaves the jet tube on the side of the paper to prevent pulp from being thrown or stained. When the roll surface is working, press the copper net 2-3 centimeters, so the wet paper is pressed, the density is increased, the surface is flat, and the paper is left the proper mesh mark. With the decrease of pressure in the compression zone, there is a certain negative pressure in the wedge zone at the exit of the compression zone. The moisture in the finish roller web is slowly dropping and part of the grout will be sucked up. Because the speed of movement in a direction perpendicular to the copper mesh must exist in the circular motion of dandy roll, thereby causing splash phenomenon.
The working principle: to drive the piston shaft using different power driven high-pressure water pipe reciprocating motion, supporting the use of simple water filter to solve nozzle clogging,
