1, packaging machine vacuum pump does not act
The trip switch is not pressed together, please close the cover, you can adjust the screw position or adjust the pressure lever to adjust the trip switch, electric open cover models, please adjust the lever.
If the relay control panel vacuum pump time relay may be damaged; if the computerized version of the control, it is the computerized version is faulty, please replace. Vacuum pump motor damage, generally this case manufacturers are given warranty (of course, the regular manufacturers), replacement or repair.
2, the vacuum chamber of the vacuum packaging machine can not reach the vacuum
Reason 1: the vacuum pump is worn or damaged, can not reach the vacuum.
Reason 2: loose gas pipe connector, pipe rupture, vacuum chamber sealing ring damage, solenoid valve damage, etc., resulting in the atmosphere into the vacuum chamber.
Reason 3: Vacuum pump oil is not enough.
Reason 4: Insufficient air time.
3, vacuum packaging machine vacuum chamber can not open
Working cycle after the bleeder solenoid valve failed to open. For fully automatic equipment, such as rolling vacuum packaging machine motorized open cover models may open the cover motor damage, lever jammed.
4, vacuum packaging products bag residual air
Sealing strip reset is not good, resulting in vacuum packaging machine pumping bag mouth pressure dead, resulting in the early closure can not be the bag of air pumped out. Packaging machine sealing pressure strip is not flexible, the bag mouth pressure dead, resulting in air can not be extracted.
5, running noise, tripping, black smoke from the exhaust port, dripping oil
Possible causes of failure are:
One: the pump motor fan scraping noise, need to be repaired.
Two: the intake port is clogged, there are foreign objects in the pump.
Three: vacuum pump oil is not enough, or the use of non-standard oil.
Three: the pump oil is not enough, or the use of non-standard oil.
Four: the pump is running for a long time, resulting in overheating, or running at high temperature, please keep the machine ventilated to dissipate the heat
Vacuum Packaging Machine is able to automatically draw out the air inside the bag to achieve a predetermined degree of vacuum and then complete the sealing process. Can also be filled with nitrogen or other gas mixture, and then complete the sealing process. Vacuum packaging machine is often used in the food industry, because after vacuum packaging, food can be antioxidant, so as to achieve the purpose of long-term preservation.
