How to troubleshoot the trouble of automatic vacuum filler machine?
When the vacuum feeder is unable to feed or the feeding capacity is small, please check according to the following procedure.
1. Whether the supply pressure of the system reaches 0.6MPA or not, the supply pressure refers to the air pressure in the system when the vacuum generator works.
2. Discharge door is tight: A. After a long period of use, the discharging door accumulates a certain thickness of powder, which causes the door to close lax and leak vacuum. The discharging door should be cleaned. B. After a long period of use, the sealing ring of the discharging door is worn out, which causes the door to close loosely and leak vacuum. The sealing ring should be replaced. C. After a long period of use, the cylinder output and stroke are out of order, so the cylinder should be replaced.
3. The filter is blocked. After the filter is blown clean with compressed air, the filter is blocked back with a nozzle. If it is very smooth, the filter is not blocked. If it feels choked, the filter has been blocked. At this time, the filter should be replaced or the blocked filter should be cleaned in an ultrasonic cleaner for more than 30 minutes.
4. Material pipes are blocked by bulk materials, which often occur at the entrance of stainless steel suction nozzle and vacuum hopper.
5. The clamps between the pump head and hopper and hopper sections are not tightened, resulting in system leakage, unable to feed or reduced feeding capacity.
6. There is a fault in the back-blowing system. The compressed air pulse back-blowing filter stored in the air bag at each discharge of the fully automatic vacuum packer ensures that only a thin layer of powder exists on the surface of the filter. If the backblow system fails, the filter surface will accumulate thicker powder, which increases resistance and makes the full-automatic vacuum filler unable to feed. At this time, the backblow valve should be replaced.
