VACUUM SYSTEM FEASIBILITY STUDY 

(Contact Us for a Quote)


CVN Vooner Paper Machinery can evaluate your vacuum services demand on your paper machine and verify both correct vacuum element sizing (uhle box, suction roll, flat box, etc.) and vacuum pump sizing on your machine before committing to a pump rebuild.

 

SERVICES
  • Orifice Plate Test Vacuum Pumps to determine airflow compared to new pump capacity and to your actual service demand.
  • Review your existing sizing of uhle boxes, suction roll box sizing, etc. for TAPPI recommended operation at your current machine conditions.
  • Review vacuum system piping, inlet & discharge separators, sealing liquid system.
  • Analyze vacuum system energy and seal water
        costs.
  • Analyze complete coverage cleaning of forming 
        wires and press felts.
  • Recommend TAPPI best practice placement of
        showers and shower oscillators.

     

    • EXPOSURE

     

    • As an internally cast iron pump is exposed to white water or process carryover, the rotor/cone clearance will increase due to corrosion and/or erosion

    With Age, "Vaneslip" occurs and airflow at vacuum declines.

    • Worn rotor vanes will allow high pressure air from the discharge segment to leak under vanes, "slip" back into the inlet segment and rob space available for new incoming vacuum airflow.
