Inflow Pressure Screen is widely used in the fine screening of wood pulp, straw pulp and waste paper pulp, especially suitable for net filter before paper machine, it has the advantage of high quality screen, low pulse and reliable operation.
Inflow Pressure Screen is a continuous screening equipment with pressure in completely closed position. When works, the pulp enters into the outside of screen drum along the tangent direction through the pulp pipe. fine pulp enter into screen drum through the sieve seam (hole), with the help of pressure difference between inside and outside of screen drum, then come out through the pulp pipe. The pulp and impurities which can not through the sieve seam (hole) fall down to the bottom, and come out from the discharge pipe. Rotating blade outside the screen drum can produce a moderate pressure, which improves the circulation flow of pulp, its tail will produce a negative pressure, which has an effect of backwash sieve seam (hole). It can prevent the sieve seam (hole) congestion, and pulp can smooth enter through the sieve screening (hole) from the surface constantly, which ensures the continuous operation.
1. Mainshaft bearing lubricated with grease, automatic oil device should be maintained in a certain oil level.
2. Cover lifting device bearing oiled once a year.
3. Triangle tape tension must be checked.
4. Always check the mechanical seal cooling water supply.
5. In order to avoid restart difficulties, when the machine stopped for a long time, the pressure screen cylinder must be carefully cleaned.
