1. The pressure of the sealing cylinder is insufficient. If you choose a low-pressure sealed cylinder, the low-pressure pressure can be kept below 8kg. General water bottle is no problem. But it also depends on the high-pressure blowing pressure. If the high-pressure blowing pressure is too high, the sealing cylinder will be pushed down. If the high-pressure pressure can be reduced, the high-pressure pressure can also be blown into the bottle to try to reduce the high-pressure pressure, or if the high-pressure pressure is too large, the clamping pressure will be reduced. If it is too small, the mold will be opened, which will also cause seal leakage, and the pressure to automatically clamp the mold can be increased.

2. Whether the sealant is damaged or in the positive sealing position, if it deviates from the sealing position, it will leak.

3. Whether the sealing cylinder or seal is damaged, if the seal is damaged, it can be directly reflected, and the solenoid valve of the sealing cylinder will know.

4. Whether the solenoid valve of the sealing cylinder is leaking or stuck or the exhaust is not stable, these are also the reasons that affect the leakage of the sealing cylinder.
