| 9. | When wind pressure of fan is deficiency or the inner sand layer of double disk is too thick , the tuyere of double disk will jam especially when moisture of sand is too high ; this jam must be treated by manually because the jam of green sand becomes very hard after air - dry and the system can not renew by itself
当鼓风机的风压不足或双盘内砂层过厚，双盘内风口会出现堵塞现象，尤其是砂子水分过高这种堵塞除非人工清理，其系统本身是无法恢复的，因为湿的砂子堵塞进风口干后会非常坚硬。 |
