如何判斷壓濾機濾板是否老化？ How to Determine If Filter Press Plates Are Aging?

壓濾機濾板（Filter Press Plates）是壓濾機最關鍵的核心部件之一，負責完成固液分離。
Filter press plates are one of the most critical components of a filter press, responsible for achieving solid-liquid separation.

隨著長時間使用，濾板會逐漸出現磨損、變形甚至破裂的情況，這不僅影響過濾效率，還可能導致整機停機。
Over time, filter plates gradually suffer from wear, deformation, or even cracking, which not only reduces filtration efficiency but can also cause machine downtime.

濾板老化的主要徵兆
Main Signs of Filter Plate Aging

• 表面磨損 – 濾板工作面出現明顯刮痕或粗糙度增加，導致濾布無法緊密貼合。
  Surface wear – Visible scratches or increased roughness on the plate surface, preventing the filter cloth from fitting tightly.
• 變形彎曲 – 長期受壓後濾板出現彎曲或不平整，影響壓緊效果與密封性。
  Deformation – Plates become bent or uneven after prolonged pressure, reducing sealing performance.
• 裂紋與破損 – 濾板邊緣或進水口處出現裂縫，嚴重時可能導致漏液。
  Cracks and damage – Cracks appear on edges or feed ports, which may cause leakage in severe cases.
• 過濾效率下降 – 出水變渾濁或濾餅含水率偏高，顯示濾板過濾功能衰退。
  Reduced filtration efficiency – Cloudy filtrate or wetter filter cakes indicate declining performance.
• 異常壓力 – 操作時壓力無法保持在穩定範圍，常見於濾板磨損或密封墊老化。
  Abnormal pressure – Operating pressure fails to stabilize, often caused by worn plates or aged seals.

濾板老化的原因
Causes of Filter Plate Aging

1. 長期高壓作業，造成塑料或陶瓷材質的疲勞損壞。
   Long-term high-pressure operation causing fatigue damage in plastic or ceramic materials.
2. 過濾液中含有大量硬質顆粒，對濾板造成磨蝕。
   Presence of abrasive solids in slurry leading to erosion of the plates.
3. 高溫或腐蝕性介質，加速濾板材質老化。
   Exposure to high temperature or corrosive slurry accelerating material aging.
4. 維護不當，如未及時更換濾布或清理殘渣。
   Poor maintenance, such as failing to replace filter cloth or clean residues promptly.

如何檢測與判斷濾板狀況？
How to Inspect and Judge Filter Plate Condition?

企業可定期對濾板進行以下檢測方法：
Factories can regularly inspect filter plates using the following methods:

• 目視檢查 – 檢查濾板表面是否有磨損、裂縫或變形。
  Visual inspection – Check for wear, cracks, or deformation on the plate surface.
• 壓力測試 – 模擬過濾過程，觀察壓力是否能維持在正常範圍。
  Pressure test – Simulate filtration process to see if pressure remains stable.
• 出水檢測 – 分析出水清澈度與濾餅乾濕度。
  Effluent analysis – Check clarity of filtrate and dryness of cakes.
• 厚度與平整度測量 – 使用卡尺或專用工具測量濾板變形程度。
  Thickness & flatness measurement – Use calipers or tools to measure deformation.
