How to troubleshoot 5 common faults in carton pressure tester

In life, cartons are common daily necessities. Similarly, cartons are very complicated in the manufacturing process. After measurement by experimental instruments, different specifications of cartons are formulated according to the bearings of different objects. Our company provides cartons according to different needs.Pressure testerThe faults are classified as follows:

Fault 1. The lower transmission chain wears and extends, affecting the normal operation of the main machine

Analysis of the cause of failure:After long-term use, the chain shaft or chain hole wear will increase the chain circumference

Maintenance method:Adjust the chain tensioner position

Fault 2. The parallelism between the upper and lower pressure plates exceeds the difference, affecting the test accuracy

Analysis of the cause of failure:1.The chain lengthening causes the two transmission screws to displace relative angularly

2.Changes in stress and strain relationship between four tension springs on the upper pressure plate

Maintenance method: 1.Adjust the chain tensioner position

2.Adjust spring tightening length

Carton pressure resistantTesting machineGeneral failure of measurement and control system

Fault 1. No display, key failure

Analysis of the cause of failure:The fuse is burnt, the power switch is damaged, the power cord is poor or loose

Maintenance method:Change the fuse, change the power switch, check and repair the power cord

Fault 2. It appears randomly after power on or during use, and the button does not work.

Analysis of the cause of failure:system”Death”

Maintenance method:according to”Reset”Key or shut down the power and restart

Fault 3. Press“Print”The key printer does not move

Analysis of the cause of failure:1.Printhead connection or poor contact

2.Printhead damaged

Maintenance method: 1.Check the print line

2.Change the print head

Fault 4. The display device does not appear or appears randomly, but other functions of the test machine are normal.

Analysis of the cause of failure:1.The display connection is slimmed or poor contact

2.The display is damaged

Maintenance method: 1.Check the line

2.Change the display

Fault 5. It appears normal, the motor working state is out of control

Analysis of the cause of failure:Motor control circuit failure

Maintenance method:Check the circuit, find out the fault and take corresponding measures (dispose by professionals)
