Causes and Solutions for Low Pressure in Dust Collectors

除塵器在陶瓷、石材、冶金、玻璃等行業中廣泛應用，用以處理粉塵與煙氣。當系統出現「壓力不足」的情況時，不僅會影響除塵效率，還可能導致設備故障甚至生產停滯。那麼，除塵器壓力不足的常見原因有哪些？又該如何處理？

Dust collectors are widely used in industries such as ceramics, stone, metallurgy, and glass to manage dust and fumes. When the system experiences low pressure, it reduces filtration efficiency and may cause equipment failure or production downtime. What causes this problem, and how can it be resolved?

壓力不足的常見原因
Common Causes of Low Pressure

• 氣源不足：氣壓系統供氣量不足，壓縮機壓力低或出現漏氣現象。
• 電磁閥故障：脈衝閥卡死或失靈，導致脈衝無法正常反吹濾袋。
• 噴吹時間設定錯誤：脈衝寬度或間隔過短或過長，導致清灰無效。
• 濾袋堵塞：長期未清灰或粉塵濃度過高，導致濾袋阻力增加。

• Insufficient air supply: Air compressor pressure is too low or there is air leakage.
• Solenoid valve malfunction: Pulse valve is stuck or unresponsive, stopping proper cleaning.
• Incorrect pulse settings: Pulse width or interval is not optimized for efficient cleaning.
• Clogged filter bags: Excessive dust accumulation increases resistance and reduces airflow.

快速排查與解決方式
Troubleshooting and Solutions

解決除塵器壓力不足的首要步驟是「逐項排查」。可參考以下流程：

To resolve low-pressure issues, follow a step-by-step troubleshooting process:

1. 確認壓縮空氣系統是否正常工作，壓力錶是否達標。
2. 檢查所有電磁閥是否開關正常，可手動觸發測試。
3. 查看控制器設定，調整脈衝間隔與寬度以提升清灰效果。
4. 打開檢修門，檢查濾袋是否破損或堵塞，視情況更換。

1. Verify air compressor performance and check pressure gauge readings.
2. Inspect all solenoid valves and test for proper opening/closing.
3. Review pulse controller settings and optimize intervals and durations.
4. Inspect filter bags for damage or blockage; replace if necessary.

預防性維護建議
Preventive Maintenance Tips

• 定期更換電磁閥膜片與彈簧，避免老化失效。
• 每月檢查濾袋阻力差壓，及時清理或更換。
• 保持脈衝管路暢通，避免積灰堵塞。

• Regularly replace solenoid valve diaphragms and springs.
• Monitor differential pressure across filter bags monthly.
• Ensure pulse piping is clean and free of obstructions.
