What are the fault maintenance of automatic spray filling machine

The fully automatic filling machine generally adds the required lubricating oil to the lubricating parts such as the reducer according to the standard before leaving the factory.
Therefore, the oil quantity needs to be controlled within the specified standard range.
The manufacturer does not guarantee that it may be bumped during transportation Cause deviation, so when the equipment is received, the equipment must be inspected, installed and debugged, and normal production activities
.

As we all know, most of our domestic equipment is 220V/380V50HZ.
Grounding protection is very important.
Therefore, it must be grounded before use.
The fault maintenance of the automatic spray filling machine has the following points: 1.
The solenoid valve fault solenoid The valve failure is mainly manifested as the cylinder does not move or reset, because the solenoid valve of the cylinder cannot be reversed or blow-by gas
.

If the solenoid valve blows air, because the air inlet and outlet are connected, the air pressure of the machine cannot reach the working pressure, and the filling head does not rise in place
.

There is a sound of air leakage in the blow-by gas of the knife solenoid valve.
If you listen carefully to the source of the sound and search for the air leakage point by hand, it is generally easy to find the solenoid valve of the blow-by gas
.

The maintenance method is to clean the solenoid valve and replace the damaged sealing ring.
If it cannot be repaired, replace the solenoid valve
.

2.
Magnetic switch failure The magnetic switch is used to detect the position of the cylinder and control the stroke of the cylinder
.

The main fault is that the follow-up cylinder does not move, because the cylinder speed is fast, so the magnetic switch cannot detect the signal
.

For example, the speed of the cylinder for pushing the packaging material is too fast, and the capping cylinder does not move after the pushing of the packaging material is reset
.

3.
Proximity switch failure The proximity switch of the automatic spray filling machine is used to detect whether the bottle is present or not, to signal the filling head, the pressure nozzle and the capping head.
The specific use of the proximity switch depends on the structure and working mode of the equipment.
to decide
.

Fourth, PLC fault PLC fault mainly has input and output point connection
.

If this point controls the motor, the fault phenomenon is that the motor runs after there is a signal to start the motor, but after the stop signal is sent, the motor does not stop running.
When the PLC is powered off, the motor stops running
.

If this point controls the solenoid valve
.

The fault phenomenon is that the solenoid valve coil is not energized and the cylinder does not reset
.

If external force is used to remove or connect the PLC to make the connection point, it can assist in judging the equipment failure
.

There are two maintenance methods for PLC output point failure.
The more convenient one is to modify the program with a programmer, modify the damaged output point to a spare output point, and adjust the line at the same time
.

If the point that controls the solenoid valve is damaged, change it to a spare point
.

If there is no programmer, the more troublesome second one can be used, dismantling the PLC, dismantling the PLC, dismantling the output relay of the spare point and replacing it with the damaged output point
.

Then install according to the original line number
