Vacuum loading machine working principle and troubleshooting method
- Dec 20, 2018 -

When the vacuum feeder fails to load or the feeding ability is small, the following six steps can be taken to solve and solve:

1. Whether the supply pressure of the system reaches 0.6MPA, and the supply pressure refers to the air pressure in the system when the vacuum generator is working.

2. Whether the discharge door is tight: A. After a long time of use, a certain thickness of powder is accumulated on the discharge door, causing the door to be closed and leaking vacuum. The discharge door should be cleaned. B. After a long period of use, the sealing ring of the discharge door is worn, causing the door to be closed and leaking vacuum, and the sealing ring should be replaced. C. After a long period of use, the cylinder output and stroke are faulty, and the cylinder should be replaced.

3. The filter is clogged. After the filter is blown off with compressed air, the filter is blown back with the nozzle. If it is very smooth, the filter is not blocked. If you feel suffocating, the filter has been blocked. In this case, the filter should be replaced. Or put the clogged filter in an ultrasonic cleaner for more than 30 minutes.

4. The material tube is blocked by large materials, which often occurs at the inlet of the stainless steel suction nozzle and at the inlet of the vacuum hopper.

5. The clamp between the pump head and the hopper and the hopper is not tightened, causing the system to leak air, unable to load or reduce the feeding capacity.

6. The backflushing system is faulty. The compressed air pulse backflushing filter stored in the air bag when the vacuum feeder is discharging is ensured that only a very thin layer of powder is on the surface of the filter. If the backflush system fails, the surface of the filter will accumulate thicker powder, increasing the resistance and causing the vacuum feeder to fail to feed. The backflush valve should be replaced at this time.
