With the development of heavy industry becoming more and more fierce, air duct seam closing machine is increasingly favored by enterprises. The air duct seam closing machine is a kind of mechanical equipment used for the joint of the air duct. When it is used normally, it can also be used together with the air duct production line 5, which significantly improves the work efficiency. However, as long as it is used for a long time, it can not avoid the possibility of failure. Today, we summarized some common fault problems and causes analysis of air duct seam closing machine. The following is answers for some problems：
The main reason: lack of butter, need to replace the new butter; the front cover is worn, need to replace the new switch valve; the parts of the striker are damaged, need to remove debris.
The main reason: the position of the reversing lever or the speed lever is wrong, the position needs to be confirmed; the oil is not enough, it needs to be refueled; the air pressure is too low, the air pressure needs to be adjusted.
The main reason: the parts of the striker are damaged, and the impact parts need to be replaced; if there is no butter, the new butter needs to be replaced.
The main reason: the switch valve has debris, need to change the impact parts; the spring breaks, need to change the new spring.
