Introduction to Maintenance Knowledge of Liquid Filling Machine

Introduction to maintenance knowledge of liquid filling machine:

1： The machine cannot start:

1. Connect the power, turn on the power switch, and check the fuse.

2. Release the emergency stop button.

3. Connect the air pressure and maintain it at around 6 kilograms.

4. Check if the switch power supply has a DC24V power output.

5. Check if the communication line between the touch screen and PLC is loose.

2： No cutting:

1. Check the air pressure and the touch screen maintenance mode screen.

2. Check if the nozzle is closed and inspect the circuit.

3. Add ingredients.

4. Check the air pressure, check if the injection cylinder and cylinder are dead, check if the discharge nozzle on the touch screen maintenance mode screen is closed, and check the circuit.

3： Inaccurate filling dosage:

1. Check the feeding system.

2. Filter and clean the materials in the pipeline.

3. Replace the sealing ring of the pneumatic valve, air pipe leakage, and replace the pneumatic valve.

4. Clean and replace the solenoid valve.

5. Clean and replace the silencing gas.

6. Adjust the ball valve to reduce impact force and increase diving depth.

7. Replace the O-ring.

8. Adjust the magnetic switch of the injection cylinder.

4： Leakage:

1. Tighten the feeding nozzle and replace the sealing gasket of the feeding nozzle.

2. Replace the discharge pipe.

3. Clean the pneumatic valve and replace the sealing gasket of the pneumatic valve.

4. Replace the sealing ring of the injection cylinder.
