灌胶机不收胶老是滴胶什么原因?
双液灌胶机收不住胶更根本的原因是密封没有做到位，漏气，漏气胶阀的回吸将起不到任何作用，从而导致收效效果不好，就像上面说的滴胶。
The fundamental reason why the double liquid glue filling machine can't hold the glue is that the seal is not in place, the air leakage, the back suction of the air leakage glue valve will not play any role, resulting in the poor effect, like the above-mentioned drop glue.
为什么会漏气呢？
Why does it leak?
一方面可能是胶阀的结构设计不合理，胶阀整体的密封性能不理想。
On the one hand, the structure design of the rubber valve may be unreasonable, and the overall sealing performance of the rubber valve is not ideal.

另一方面胶阀的密封性可以，但是内部空间不合理，造成背压，也就是压力不能迅速的释放不出来，造成胶水从顶端冒出，漏胶，滴胶。
On the other hand, the sealing performance of the glue valve is OK, but the internal space is unreasonable, resulting in back pressure, that is, the pressure can not be released quickly, resulting in glue emerging from the top, glue leakage and glue dripping.
再者，也可能是胶阀长时间使用，密封圈磨损，导致漏气收不住胶。
Moreover, it may also be that the rubber valve is used for a long time, and the sealing ring is worn, resulting in air leakage and rubber failure.

还可能的情况是，胶水有腐蚀性，密封圈所用的材料不是耐腐蚀的，密封圈被腐蚀了，收不住胶。
It is also possible that the glue is corrosive. The materials used for the sealing ring are not corrosion-resistant. The sealing ring is corroded and cannot hold the glue.
双液灌胶机综上解决此类问题，要么从胶阀的结构上改良，将胶阀的密封性做好。另一方面就是定期更换密封圈，用耐腐蚀的密封圈。
In order to solve these problems, we should improve the structure of the rubber valve and make the sealing of the rubber valve well. On the other hand, replace the sealing ring regularly, and use the corrosion-resistant sealing ring.
