12. Is there any inaccurate filling in the piston filling machine? Under what circumstances will the filling be inaccurate?
When the piston filling machine is not accurate, it may be caused by the following reasons:
(1) While using filling tubes, the air in the tube may not completely emptied. Accurate filling can be achieved by simply resetting when air exhausting in the tube.
(2) It may be that the total pressure is unstable. Please check the pressure stability of the air compressor and whether the air storage capacity of the air reservoir is sufficient to supply the filling machine.
(3) The operation of the on-off valve is not complete. If the valve of the filling machine is stuck with foreign materials and the switch is not completely switched, please remove the foreign materials before filling it.
