Vacuum suction box for paper making machine

Vacuum suction box is the traditional vacuum dewatering part for paper making machine. When the pulp reaches the vacuum suction box, the concentration has reached 2% -3%,the purpose of the
vacuum suction box is to increase the pulp concentration by the suction effect of the vacuum pump.
In general, on low speed paper machines, the pulp concentration can reach about 11% after passing through the
vacuum suction box; on high-speed paper machines, the pulp concentration can reach as high as 15% or more after
the vacuum suction box.

 

On different paper making machines,The number of vacuum suction box depends
on the type of paper. The vacuum suction box number in high grade paper making machine or high speed paper making machines is relatively more.When finished paper weight in paper making machine changes,
the vacuum degree of the vacuum suction box can be adjusted to ensure the paper dryness.

Noted:Vacuum suction box for paper making machine

1.In order to adapt to changes in the dryness of wet paper sheets, the vacuum degree of the vacuum suction box
should be gradually increased.

2.Can’t just increase the vacuum degree to force dehydration, which accelerates the wear of the forming fabric,
increases the power to drive the forming fabric, improves the forming fabric tension, and has a negative impact on the life
of the forming fabric.
