Low Pressure Shower

 

Low-Pressure Shower (NOT) for Wires and Felts Cleaning and Conditioning

Low-pressure showers play a crucial role in cleaning and conditioning wires and felts in paper machines. They significantly influence the lifespan of the felt and screen, the productivity of the paper machine (PM), the quality of the produced paper, and energy consumption.

Functionality and Types

Low-pressure showers are categorized based on their functions:

  • Moisturizing: Adds moisture to the wire or felt.
  • Cleaning: Removes debris and contaminants.
  • Lubricating: Reduces friction and wear.
  • Intensive: Provides deep cleaning.
  • Condensing: Concentrates moisture in specific areas.
  • Flooding: Delivers high volumes of water.
  • Trims Showering: Cleans edges and trims.

Design Features

  • Material: Constructed from stainless steel for durability and resistance to corrosion.
  • Standard Versions: Available in three sizes:
    • Shower with Ø 60.3 mm, mounting pitch up to 3,500 mm.
    • Shower with Ø 76 mm, mounting pitch up to 5,500 mm.
    • Shower with Ø 108 mm, mounting pitch up to 7,000 mm.
  • Nozzles: Equipped with flat jet nozzles, sizes 1 to 3, positioned 80 – 120 mm from the wire or felt.
  • Cleaning Mechanism: Includes an internal cleaning brush for removing impurities from the nozzles and inner surface. The brush is operated manually using a wheel on the operator side, which also opens the valve for waste water outlet.
  • Water Supply: Connection on the opposite side for water supply. Pipes have fixed or pressed nozzles for efficient water distribution.

Main Parts

  1. Shower with Nozzles: The primary cleaning component.
  2. Cleaning Brush: Removes impurities from nozzles and internal surfaces.
  3. Water Supply Connection: Provides clean water for the shower.
  4. Cleaning Brush Wheel: Allows manual operation of the cleaning brush and waste valve.
  5. Waste Piping for Sediments Outlet: Disposes of collected impurities.
  6. Stands for Shower Pipe Fitting: Supports the shower pipe.

Material

  • All parts are made of stainless steel for longevity and resistance to corrosion.

Accessories

  • Inlet and Outlet Water Hose: For connecting to the water supply.
  • Sealing Fittings: Ensure leak-free connections.
  • Stainless Piping for Water Supply: Provides durable and efficient water distribution.

Scope of Delivery

  • Complete equipment as per the main parts description.
  • Optional accessories available upon request.

Water Quality Requirements

  • Clean Water: Max. water contamination 50 mg per liter.
  • Industrial Water: Max. water contamination 9 – 12 mg SS per liter.
  • Max. SS Size: 20 μm (SS = suspended solids, insoluble in water).

Shower Connection

PAPCEL provides complete shower connections, individually or in groups, to the machine water distribution system. This includes assembly, startup, and operator training.

Advantages

  • High Cleaning Efficiency: Ensures proper functioning of screens and felts.
  • Durable Construction: Made of stainless steel for extended service life.
  • User-Friendly: Easy maintenance and operation.
  • Customizable: Various nozzle sizes and mounting options to suit specific needs.

These features make low-pressure showers an essential component for maintaining the cleanliness and efficiency of wires and felts in paper machines, ultimately enhancing the overall performance and quality of paper production.
