Paper Making Nozzle
NeedleJet Spray Nozzle
A NeedleJet spray nozzle delivers a focused, high-velocity stream of liquid through a narrow orifice, which is required when precise impact force or penetration is needed through dense material layers, such as in paper web washing or surface cleaning in high-speed paper machines. This CNSS NeedleJet range is designed for consistent performance in continuous paper making lines where uniform water distribution and controlled impact are critical to sheet integrity and process stability.

Comparison
How It Compares With the Alternatives
| Flat fan nozzle | A flat fan spreads liquid across a surface, suitable for broad coverage, while a NeedleJet delivers a focused jet for penetration into dense layers like wet paper web |
|---|---|
| Full cone nozzle | A full cone provides even coverage over a circular area, ideal for tank filling, but lacks the focused impact of a NeedleJet for targeted surface cleaning |
| Hollow cone nozzle | A hollow cone creates a ring pattern with fine droplets, better for gas scrubbing, but cannot deliver the concentrated jet needed for deep web penetration |
| Spiral nozzle | A spiral handles solids better due to external vane design, but its pattern is not suitable for precise, high-impact jet applications in paper making |
Use Guide
Fitting and Running It
- Confirm the required jet velocity and impact point based on the paper web thickness and speed
- Ensure the nozzle is aligned with the target surface to avoid misdirection
- Use external threads to connect directly to standard pipe fittings without adapters
- Check the orifice for blockage or wear if jet performance drops
- Secure the hex base with proper torque to prevent loosening during operation
- Verify the material selection matches the chemical and temperature conditions of the service
