, common fault causes and elimination method
Fault a: vacuum pump does not work or has serious noise reasons: 1, link up the phase indicator or fuse circuit;
2, vacuum pump inversion;
3, IC main contact point contact undesirable.
4, ISJ normally closed contact undesirable.
Method: 1, check the power supply into line or in molten core.
In phase 2, power.
3, adjust or change new.
4, adjust or change new.
Fault 2: no heat sealing reasons: 1, nickel chrome leather burn.
2, heat sealing back line is loose, open circuit.
3, 2 c, the main contact point contact undesirable.
4, 2 c didn't work.
Method: 1, to be renewed.
2, twist, and reconnect.
Pump valve 3, adjust or change new imports.
4, check the sj 1 2 sj normally closed normally open contacts are in good condition.
Fault 3: vacuum reason: not or no 1, the bags leak.
2, vacuum heat sealing no vacuum chamber.
3 and 1 dt core on gasket or magnetic seal leakage in the bubble.
Method: 1, the new packaging.
2, 1 dt doesn't work, repair or change new.
Fault 4: short of provisions limiting vacuum of reasons: 1, vacuum pump oil is too little, or pollution.
2, vacuum pump smoke or gas leakage.
3, pneumatic closed tightly.
4, 2 dt core card death reset.
Method: 1, gas or oil change.
2, cleaning vacuum pump, a new exhaust filter, check the check valve.
3, check the gas path, to eliminate leakage.
4, maintenance or cleaning.
Five: fault sealing surface uneven or corrosion reasons: 1, the temperature regulation is too high too long.
2, 2 sj doesn't work.
Method: 1, to readjust.
2, repair or change new (
Found that heat sealing delay very long, should be promptly cut off the power supply)
Fault 6: the sealing strength is not enough reason: 1, the low temperature regulating time is too short.
2, vacuum time adjustment is too short.
3, heat sealing chamber breakdown elimination method: 1, to readjust.
2, to readjust its & le;
