Maintenance of large vertical packing machine.
1. The vacuum packaging machine should be used in the environment where the temperature is - 10 ℃ - 50 ℃, the relative humidity is not more than 85%, and there is no corrosive gas, dust and explosive danger in the surrounding air. Like the packer and shrinker, the vacuum packer has a three-phase 380V power supply.
2. In order to ensure the normal operation of vacuum pump, the motor of vacuum pump is not allowed to reverse. Oil should be checked frequently

The normal oil level is 1 / 2-3 / 4 of the oil window (can not be exceeded). When there is moisture in the vacuum pump or the oil color turns black, the new oil should be replaced at this time (generally, the oil should be replaced once every two months after continuous operation, and 1 × 10 vacuum gasoline or 30 × gasoline and engine oil can also be used).
3. The impurity filter should be removed and cleaned frequently (generally, it should be cleaned every 1-2 months, for example, the cleaning time should be shortened if the package is fragmented).
4. After 2-3 months of continuous operation, the back cover should be opened, 30 pairs of sliding parts and switch bumpers should be lubricated, and the connection active parts on the heating rod should be lubricated according to the service conditions.
5. Check the pressure reducing, filtering and oil mist triple parts 24 frequently to ensure that there is oil (sewing oil) in the oil mist and oil cup, and there is no water in the filter cup.
6. The heating strip and silica gel strip shall be kept clean, and no foreign matters shall be stuck to avoid affecting the sealing quality.
7. The two layers of paste on the heating rod and under the heating plate play an insulating role. When it is damaged, it should be replaced in time to avoid short circuit.
8. The working pressure of vacuum packing machine has been set to 0.3MPa, which is more appropriate. Do not adjust it too much without special circumstances.
9. The vacuum packaging machine is not allowed to tilt and impact in the process of handling, let alone put down for handling.
10. The vacuum packing machine must have reliable grounding device during installation.
11. Do not put your hand under the heating rod to prevent injury. Cut off the power supply immediately in case of emergency.
12. When working, ventilate first and then turn on power; when shutting down, cut off power first and then cut off gas. Large vertical packing machine
