Troubleshooting Of Quantitative Filling Machine
1, Inaccurate filling volume
When filling large specifications, insufficient filling in the material tank can cause unstable liquid level. To solve this problem, increase the amount of filling or close the ball valve above the filling head again, reset the filling time (extend the filling time), and slow down the filling speed.
2, After adjusting the number dial or unit, the time does not change. At this time, turn off the power and reconnect the power.
3, Stable liquid level, inaccurate filling amount
There are debris blocking the filling channel, mainly at the inlet of the material tank or in the filling mouth. Check and clean it thoroughly.
4, Dripping after closing
1. The filling nozzle hole is damaged, and the filling nozzle can be removed to repair the hole. The diameter of the hole cannot exceed 7.5mm. After repairing the aperture, gently grind the flat surface of the hole on a water frosted paper.
2. The ball valve inside the filling head is damaged and needs to be replaced.
5, After touching the injection switch, the material will not be filled, and the digital indicator LED of the time relay will not flash:
If the injection switch is damaged or the time relay base is loose, replace it with the same model of injection switch or tighten the time relay base.
6, After touching the material injection switch, the digital LED indicator light of the time relay flashes, but the material is not filled:
Firstly, check if there is air pressure or if the air pressure is too low. If the air pressure meets the requirements (4-6 Kg/cm2), it may be due to damage to the solenoid valve coil or blockage of the pneumatic valve core by dirt. You can unplug the power supply, open the board, rotate or press the corresponding button next to the solenoid valve coil. If the valve can change direction, it means that the solenoid valve coil is damaged. If it cannot be reversed, it is due to blockage of the valve core. You can replace the solenoid valve coil or disassemble the valve for repair (electricians or those with pneumatic knowledge are required to disassemble or inspect).
