A: External pumping vacuum packaging machine alarm reasons:
The external vacuum packaging machine is equipped with an alarm indicator for better normal use of the vacuum machine and to facilitate troubleshooting of the vacuum machine. The following is the analysis of the cause of the alarm of the external vacuum packaging machine
1. The air source is not turned on, or the air source is not enough, check whether the air source is open or the air source pressure is above 6kg.
2. The upper sensor of the pressure bar is bad or the position is not suitable. Replace the sensor and adjust the sensor to the proper position. Under normal conditions, the pressure bar is in the upper position and the sensor indicator light is on.
3. Improper operation, at least one indicator light in the manual and automatic gears is on, in order to operate normally. Otherwise, the indicator light will be alarmed after the foot switch is pressed.
Two: the external pumping vacuum packaging machine does not work
The working principle of the external vacuum packaging machine is different from that of the food vacuum packaging machine. The operation method is that after the gas source is turned on, the suction nozzle is extended, the sealing strip is pressed, and the vacuum pump starts to work. After the vacuum is completed, the suction nozzle is recovered and the sealing strip is heated. In the course of use, there are often cases where the suction nozzle does not move. There are several reasons for this:
1. The air source is not connected: this situation often occurs. After the power is turned on, the external vacuum packaging machine does not operate, the machine does not stop alarming, and most of them are not connected to the air source.
2. Mode error: three modes of external vacuum packaging machine, vacuum mode, sealing mode, and inflation mode. In addition to pumping vacuum, the external vacuum packaging machine can also be used as a sealing machine, and when it is in the sealing mode, the suction nozzle does not work, so some customers will operate incorrectly, and the external vacuum packaging machine does not. jobs.
3. Cylinder failure: The external pumping vacuum packaging machine has two cylinders to control the action of the sealing strip pressing and pumping the cylinder. When the suction nozzle does not respond and the above two reasons are excluded, check whether the cylinder of the vacuum packaging machine is faulty.
