The spray pipe is mounted on the paper machine rack for cleaning roller surface. The roller has a jet tube on the inside of the page to prevent slurry or paper. When the roller surface works normally, press the copper network down 2 to 3 cm, so the wet paper is pressed tightly, the density increases, the surface is horizontal, and the surface is left with the proper net mark. With the pressure drop in the pressure zone, there is a certain negative pressure in the wedge area of the outlet side of the pressure zone. The water in the face roller net slowly falls down, and the part of the slurry will be sucked up. As the circular motion of the decorative roller must exist in the direction of the direction of the movement perpendicular to the copper network, it can cause the splashing phenomenon.

Its working principle: by using different power to drive the piston shaft, drive the high pressure water spray reciprocation, supporting the use simple water filter to solve nozzle clogging, however high pressure water can efficiently through needle nozzle flush paper pilot nets, rotary screen and blanket, thickener and a variety of washing equipment; Or wet blanket with a fan nozzle. The best flushing effect is achieved. Namely, reciprocating a secondary blanket blanket.
