Self-Cleaning Shower Pipes
Self-cleaning shower pipes are widely used in the pulp and paper industry for washing and cleaning forming fabrics and felts. There are two main types of shower pipes:
Low-pressure (2–6 bar) static pipes equipped with GE flat fan nozzles
High-pressure (25–70 bar) oscillating pipes equipped with GEA straight jet nozzles
Key Features:
- Integrated cleaning system that simultaneously cleans the nozzles and discharges impurities.
- Quick and easy activation of the cleaning system without interrupting the spray process or causing issues for operators.
- Water-saving nozzles are designed to prevent clogging, even after extended use.
Shower pipes meeting these three criteria consist of three main components:
- Assy Valve
- Assy Shaft
- Assy Pipe
Component Functions:
- Assy Valve: Controls the discharge flow by opening or closing a lock, which is operated manually via a handwheel. The Assy Valve is flanged to the Assy Pipe and connected to the discharge system via a threaded or hose fitting.
- Assy Shaft: A pipe fitted with specific brushes that move radially and axially when connected to the shaft of the Assy Valve. This movement enables the brushes to remove impurities from both the nozzles and the inner surface of the Assy Pipe.
- Assy Pipe: The nozzles are mounted on this pipe, which is connected to the main supply line. Nozzles can be installed using either welding nipples or ZPH plastic pipe clamps.
