除塵器壓力不足的原因與解決方法
Causes and Solutions for Low Pressure in Dust Collectors

在陶瓷、石材、玻璃等行業中，脈衝除塵器（Pulse Jet Dust Collector） 是最常見的粉塵治理設備。它通過壓縮空氣清理濾袋，使粉塵脫落並保持系統穩定運行。
In industries such as ceramics, stone, and glass, the Pulse Jet Dust Collector is the most common dust control device. It uses compressed air to clean filter bags, dislodging dust and ensuring stable operation.

然而，在實際使用中，除塵器經常出現壓力不足（Low Air Pressure）的情況，導致清灰不徹底、濾袋堵塞，甚至吸力下降。
However, in real-world operation, low air pressure often occurs, resulting in poor cleaning, clogged bags, and reduced suction efficiency.

壓力不足的主要原因
Main Causes of Low Pressure

1. 氣源供應不足：空壓機壓力低或氣管漏氣，是最常見的原因之一。
   Insufficient air supply: A weak compressor or air leakage in pipes is one of the most common causes.
2. 電磁閥故障：若脈衝電磁閥（Solenoid Valve）堵塞或損壞，反吹氣流無法正常釋放。
   Solenoid valve malfunction: If the pulse valve is clogged or damaged, reverse air cannot be released properly.
3. 濾袋堵塞：長期未清灰或粉塵潮濕，造成氣流阻塞與壓力下降。
   Clogged filter bags: Prolonged use without cleaning or humid dust causes blockage and pressure loss.
4. 控制系統設定錯誤：脈衝間隔過短或過長，都會影響清灰效果。
   Improper control settings: Incorrect pulse timing—too short or too long—affects cleaning performance.
5. 氣包積水：未安裝排水閥或環境濕度高，導致氣壓異常波動。
   Moisture in air tank: Without a drain valve, water buildup in the air tank causes unstable pressure.

解決方法與保養建議
Solutions and Maintenance Tips

• 🔧 檢查氣源壓力：確認空壓機輸出壓力達 0.5–0.7 MPa，並定期排除氣管積水。
  🔧 Check air supply: Ensure the compressor pressure reaches 0.5–0.7 MPa and drain moisture regularly.
• ⚙️ 測試電磁閥反應：聽取脈衝聲音是否正常，或使用手動開關測試開閉狀態。
  ⚙️ Test solenoid valves: Listen for consistent pulse sounds or test the on/off response manually.
• 🧹 定期更換濾袋：建議每 12–18 個月檢查濾袋磨損情況，必要時更換。
  🧹 Replace filter bags regularly: Inspect bags every 12–18 months and replace when worn.
• ⚡ 優化控制系統：調整清灰時間與間隔，使除塵與過濾效率達到平衡。
  ⚡ Optimize control settings: Adjust pulse intervals to balance cleaning and filtration efficiency.
• 💧 保持氣包乾燥：加裝自動排水閥或定期放水，防止水氣進入氣路。
  💧 Keep air tank dry: Install an automatic drain or discharge water manually to prevent air moisture.
