The following are common faults and solutions for crystal mud filling machines:

Throttle Valve Issues: The speed throttle valve and the filling interval throttle valve are closed, resulting in unstable material flow and thus affecting the filling volume.

Foreign Objects in Control Valve: There are foreign objects in the quick-install three-way control valve, or there is air in the hose between the quick-install three-way control valve and the filling head, which obstructs or destabilizes the material flow.

Damaged Sealing Ring: A damaged sealing ring will cause material leakage, affecting the accuracy of the filling volume.

Problems with the Filling Nozzle Spool: The spool of the filling nozzle is stuck or opens with a delay, resulting in poor material outflow and insufficient filling volume.

Too Fast Filling Speed: If the filling speed is too fast, the material doesn't have enough time to accurately fill the container, which also leads to inaccurate filling volume.

Check and adjust the throttle valves to ensure they are in an appropriate open state so that the material can flow out stably.

Clean the foreign objects in the quick-install three-way control valve and at the same time expel the air in the hose. This can be achieved through multiple filling operations or by using a special air exhaust tool.

Replace the damaged sealing ring to ensure good sealing and prevent material leakage.

Reinstall the spool of the filling nozzle to ensure its correct position. If it opens with a delay, adjust the throttle valve of the thin cylinder to control the opening speed of the spool.

Appropriately adjust the filling speed throttle valve to reduce the filling speed so that the material can fully and accurately fill the container.

Installation Problems of Filling Head: The filling head is not installed properly, and there may be looseness or poor sealing, resulting in material leakage from the filling head.

Damage to the Filling Nozzle: The opening of the filling nozzle is damaged, making it impossible to control the normal outflow of the material, thus causing leakage.

Damage to the Ball Valve: The ball valve inside the filling head is damaged, unable to effectively control the on-off of the material, thus causing leakage.

Problems with O-ring: The O-ring of the piston in the material cylinder is damaged, which will cause material leakage from the rear end of the material cylinder.

Check the installation of the filling head to ensure it is firmly installed and well sealed. If necessary, reinstall the filling head.

Remove the filling nozzle, trim the opening to make its diameter meet the requirements, and gently smooth the plane of the opening on the wet sandpaper. However, be careful not to over-polish and enlarge the opening.

Replace the damaged ball valve to restore the normal control of the material by the filling head.

Replace the damaged O-ring in a timely manner to prevent material leakage from the rear end of the material cylinder.

Power Supply Problems: Problems with the power switch, blown fuses, no output from the switching power supply, etc., result in the filling machine being unable to obtain a normal power supply.

Emergency Stop Button Not Reset: The emergency stop button has not been reset after being pressed, leaving the filling machine in a stopped state and unable to start.

Loose Communication Cables: The communication cables between the touch screen and the PLC are loose, resulting in poor signal transmission and affecting the start of the filling machine.

Check whether the power switch is normal. If it is damaged, replace it in a timely manner. Check whether the fuse is blown. If it is blown, replace it with a fuse of the same specification. Measure the output voltage of the switching power supply to ensure normal power supply.

Check the state of the emergency stop button and reset it to release the filling machine from the stopped state.

Check the connection of the communication cables between the touch screen and the PLC. Reinsert the loose cables tightly to ensure normal signal transmission.

Machine Malfunctions: Such as motor malfunctions, damage to transmission components, cylinder malfunctions, etc., which cause the filling machine to be unable to operate normally.

Overload Protection Triggered: The filling machine runs for a long time or has an excessive load, triggering the thermal overload protection and causing the equipment to stop automatically.

Insufficient Air Pressure: The air pressure required for the pneumatic components is insufficient, unable to ensure the normal operation of the filling machine, thus resulting in a shutdown.

Check machine components such as motors, transmission components, and cylinders to see if there are any damages or abnormalities. If there are problems, replace or repair the damaged components in a timely manner.

Find out the reasons for triggering the overload protection, such as whether there is material blockage, excessive load, etc. After eliminating the faults, press the reset button to restart the filling machine.

Check the air pressure system to ensure that the air pressure valve is open and the air pressure meets the normal working requirements. If the air pressure is insufficient, adjust the air pressure valve to increase the air pressure.

Material Blockage: The material contains impurities or crystals, which cause blockages in the pipes, valves, or filling nozzles, affecting the normal flow of the material.

Pipe Problems: The pipes are bent, deformed, or have internal wear, increasing the resistance to material flow and slowing down the flow rate.

Pneumatic Component Malfunctions: Malfunctions of pneumatic components such as cylinders and solenoid valves, which are unable to normally push the material to flow.

Clean the impurities and crystals in the material and at the same time check the pipes, valves, and filling nozzles to remove the blockages and ensure the material can flow smoothly.

Check the installation of the pipes. If there are bends or deformations, adjust or replace the pipes in a time. For pipes with severe internal wear, they should also be replaced.

Check the working state of the pneumatic components, such as whether the cylinders are leaking air, whether the solenoid valves are switching normally, etc. Repair or replace the faulty pneumatic components.
