Explain why the suction cup of the glass edging machine is unstable

     The reason why the suction cup of the fast glass edging machine is unstable may be caused by the following reasons:

1. Check if the suction cup of the glass edging machine is leaking.

2. Check—the suction cup pressure of the lower glass edging machine is enough, see the vacuum gauge, the pressure is greater than 0.08.

3. Check if the storage tank is blocked, if there is gas, and if it is blocked.

4. Whether the cylinder is stuck and whether it is in place.

5. Check if there is water in the inlet water of the vacuum pump and if there is water flowing out of the outlet.

6. Whether the vacuum pump is running.
