How to Determine If Filter Press Plates Are Aging

在壓濾機的日常運行中，濾板是直接承受壓力與過濾任務的核心部件。
In the daily operation of a filter press, the filter plates are the core components that bear pressure and perform filtration.

隨著時間與高強度使用，濾板會逐漸老化，影響過濾效率與出水品質。
Over time and under heavy use, filter plates gradually age, reducing filtration efficiency and filtrate quality.

那麼，如何判斷濾板是否需要更換？以下幾點是常見的判斷依據。
So, how do you determine whether filter plates need replacement? The following are common indicators.

1. 濾板表面出現裂痕或變形
1. Cracks or Deformation on the Plate Surface

長期承受高壓後，濾板可能出現細小裂紋或明顯彎曲。這會導致密封不良，甚至在運行過程中漏水或破裂。
After long-term high pressure, plates may develop small cracks or significant bending. This causes poor sealing and may result in leakage or plate breakage during operation.

2. 濾餅脫落困難
2. Difficulty in Releasing Filter Cakes

若濾餅經常粘附在濾板上，即使清洗後依舊不易脫落，可能意味著濾板表面材質已磨損或老化。
If filter cakes frequently stick to the plates and remain hard to remove even after cleaning, it may indicate surface wear or aging.

3. 出水濁度升高
3. Increased Filtrate Turbidity

當出水水質逐漸變差，濁度升高，通常是因為濾板表面的微孔結構受損或堵塞，無法達到原有的過濾效果。
When filtrate quality declines and turbidity increases, it usually means the microstructure of the plate surface has deteriorated or clogged, reducing filtration performance.

4. 濾板密封條磨損
4. Worn Sealing Strips

濾板邊緣的密封條若出現磨損或硬化，將導致過濾過程中漏液或壓力下降。
If the sealing strips on plate edges are worn or hardened, it will cause leakage and pressure loss during filtration.

5. 運行壓力異常
5. Abnormal Operating Pressure

若壓濾機需要頻繁調整壓力才能保持正常運行，這可能與濾板變形或老化有關。
If frequent pressure adjustments are needed to keep the machine running, it may be related to plate deformation or aging.

如何延長濾板使用壽命？
How to Extend Filter Plate Lifespan?

• 避免超壓操作，遵守額定工作壓力。
  Avoid overpressure and operate within rated pressure limits.
• 定期清洗濾板，防止顆粒堵塞表面孔隙。
  Clean plates regularly to prevent particle clogging in pores.
• 使用適合物料特性的濾布，降低對濾板的磨損。
  Use filter cloths suitable for slurry properties to reduce plate wear.
• 定期檢查密封條並及時更換。
  Inspect sealing strips regularly and replace them when needed.

結語
Conclusion

濾板雖然只是壓濾機的一個部件，但卻直接決定了整台設備的運行效率與使用壽命。
Although filter plates are only one component of a filter press, they directly determine the efficiency and lifespan of the entire machine.
