Methods to solve common faults of pneumatic liquid quantitative filling machine: 1. How to solve the problem of inaccurate filling quantity of pneumatic liquid quantitative filling machine? When filling large specifications, the Hopper is insufficient in feeding, resulting in unstable liquid level. The feeding amount can be increased or the air valve above the small cylinder can be turned off again to reset the filling time (Longer filling time)Slow down the filling speed to solve. Second: the liquid level of the filling machine is stable. Why is the filling quantity inaccurate? There are sundries blocking the filling channel, mainly at the Hopper entrance or in the filling mouth, check and clean it. Three: How can the filling machine drip after it is closed? In case of such a failure, the filling mouth may be damaged. The filling mouth can be taken out, and the filling mouth can be gently smoothed on the water grinding sandpaper after the filling mouth is repaired, another possibility is that the sealing ring in the filling head is damaged and the sealing ring needs to be replaced. :
