W. COOLER EXIT TEMP TOO HIGH 冷却器出口饲料温度太高 1. Not enough CFM – 1,000 CFM/ton 风量不够－1,000 CFM/ton 2. Screens blocked隔栅堵塞 冷却器隔栅堵塞 3. Too low retention time – bed depth too thick or too thin 停留时间太短－料床太厚或太薄 4. Pellet discharge to cooler bed not sealed with product resulting in air flow through the top of the cooler 颗粒排料到冷却器时隔栅密封不好导致气流穿过冷却器顶部 5. Very high ambient temperature 环境温度非常高 6. Improper plenum on cooler so air is pulled only from one spot – i.e., Farr Better 冷却器内气流从一点被排出. 7. Ducting plugged风管堵塞 风管堵塞 8. Air lock baffle belts worn 关风器挡板磨损 9. Bed uneven across cooler pans 冷却器隔栅的料床不平均 10. Screen not covered due to pellet mill starting and stopping 由于制粒机启动或关闭时冷却器隔栅不能被关闭 11. Fan damper set wrong风机风门设置 风机风门设置错误 12. Product hung up in cooler 冷却器内物价改革料结拱 13. Cube stuck in cooler bindicator – runs all the time冷却器料位器堵塞---总是运行 冷却器料位器堵塞---总是运行 14. Cooler too small 冷却器太小 15. Ambient high humidity 相对环境湿度太高 |
