Vacuum packaging machine maintenance and troubleshooting methods

The vacuum packaging machine maintenance and troubleshooting are as follows:

Fault phenomenon

Cause exclusion

Vacuum pump is not working or there is serious noise 1. The phase of the power supply is missing or the fuse is open

2, vacuum pump reversed

3, poor contact of the main contact points of the IC

4, ISJ normally closed contact bad 1, check the power into the line or change the fuse

2, power supply commutation

3, adjust or replace new

4, adjust or replace new

Vacuum pump over time ISJ does not work overhaul or replace new

Failure to reach the specified ultimate vacuum degree 1, too little vacuum pump oil or contamination

2, the vacuum pump smoke or leak

3, gas circuit closed is not tight

4, 2DT iron core stuck not reset 1, refueling or oil change

2. Clean the vacuum pump, replace the exhaust filter, check the check valve

3, check the gas path, eliminate leaks

4, maintenance or cleaning

Incomplete vacuum or no vacuum, leakage of bag

2, vacuum sealing chamber without vacuum

3, 1DT core seal or magnetic cover seal leakage 1, new packaging bags

2, 1DT does not work, troubleshooting

3, maintenance or new

No heat seal 1, Nichrome burned

2, heat seal circuit line loose, open circuit

3, 2C bad main contact

4, 2C does not work 1, change new

2, tighten, reconnect

3, adjust or replace new

4, check 1SJ normally open 2SJ normally closed contact is good

Seal strength is not enough 1, the temperature time adjustment is too low and too short

2, vacuum time adjustment is too short

3, heat seal air chamber rupture

1, re-adjustment

2, re-adjust it to ≤ -0.08Mpa

3, change new

The sealing surface is uneven or eroded 1. The temperature is adjusted too long

2, 2SJ does not work 1, re-adjust

2, repair or renew (found heat seal delay is long, should be cut off in time)

After the end of the heat seal No return 1,2SJ normally open bad contact

2, 2DT does not work 1, adjust or replace new

2, repair or troubleshooting
