Adhering to installation and maintenance guidelines ensures compliance with warranty terms and maximizes screen lifespan.
Proper handling and operation of filter screens are essential for safe and efficient production.
Inspect screens for scratches, deformation, or corrosion before installation.
Align the screen precisely with the housing or filter element.
Apply uniform compression using end caps or clamps to prevent leakage.
Avoid over-tightening to maintain mesh integrity.
Monitor pressure and flow during initial operation to confirm proper installation.
Check pressure drops to identify clogging early.
Inspect for abnormal vibrations or noises that may indicate misalignment.
Keep the production environment clean to minimize contamination risk.
Mechanical Cleaning: Use soft brushes or compressed air to remove polymer residues.
Chemical Cleaning: Apply mild solvents; avoid corrosive chemicals.
Ultrasonic Cleaning: Recommended for heavily contaminated screens to ensure thorough cleaning without damaging the mesh.
Upgrading filter screens can enhance their performance and adapt them to evolving production needs.
High-Precision Mesh: Improves filtration efficiency for fine polymer fibers.
Reinforced Mesh: Increases durability under high-pressure conditions.
Multi-Layer Mesh Designs: Enhances filtration without reducing flow rate.
Aluminum or Stainless Steel Frames: Increase structural integrity and resist corrosion.
Welded or Bolted Frames: Provide additional support in high-stress applications.
Polished or Anodized Coatings: Reduce polymer adhesion and simplify cleaning.
Anti-Stick or Anti-Corrosion Coatings: Improve longevity in harsh environments.
Extended operational life
Improved filtration efficiency
Reduced production downtime
Enhanced nonwoven fabric consistency
Even durable filter screens may experience issues if not maintained properly.
| Issue | Possible Cause | Recommended Solution |
|---|---|---|
| Excessive Pressure Drop | Clogged mesh | Clean or replace mesh; review maintenance schedule |
| Uneven Fiber Formation | Partial blockage or damaged mesh | Inspect, clean, or replace screen; verify installation alignment |
| Polymer Contamination | Leakage around the screen housing | Check gasket sealing and alignment |
| Mesh Deformation | Over-tightening or mechanical impact | Replace screen; follow proper installation procedures |
Regular inspections, preventive maintenance, and timely upgrades minimize these issues and maintain consistent nonwoven fabric quality.
