The maintenance of vacuum packaging machine is a problem faced by any company after sale. As consumers and vacuum users, we should learn more about the common problems of vacuum packaging machine for future normal work and maintenance. The following small series has compiled some daily use precautions, I hope to have some help for everyone.
1. The vertical vacuum packaging machine should be used in an environment where the temperature is -10 °C - 50 °C, the relative humidity is not more than 85%, there is no corrosive gas in the surrounding air, no dust, no explosion hazard. Like the baler and shrink machine, this vacuum packaging machine is a three-phase 380V power supply.
2. Ensure that the vacuum pump works normally for the vacuum packaging machine, and the vacuum pump motor is not allowed to reverse. The oil level should be checked frequently. The normal oil level is 1/2-3/4 of the oil window (cannot be exceeded). When there is moisture in the vacuum pump or the color of the oil turns black, the new oil should be replaced at this time (usually one or two continuous working) Change once a month, use 1# vacuum gasoline or 30# gasoline, oil can also be).
3, the impurity filter should be frequently removed and washed (usually once every 1-2 months, such as packaging debris should shorten the cleaning time).
4. For 2-3 months of continuous operation, the rear cover 30 should be opened to add lubrication to the sliding parts and the switch bumps. The connection activities on the heating rods should be lubricated according to the usage.
5, the decompression, filtration, oil mist triplet 24 should be checked frequently to ensure that there is oil in the oil mist, oil cup (sewing machine oil), no water in the filter cup.
6. The heating strip and the silicone strip should be kept clean and free of foreign matter, so as not to affect the quality of the seal.
7. On the heating rod, the two layers of adhesive under the heating sheet will be insulated. When there is damage, it should be replaced in time to avoid short circuit.
8. The user-supplied working air source and inflation air source, the working pressure of the vacuum packaging machine has been set to 0.3 MPa, which is more suitable, and no special situation is not adjusted too much.
9. The vacuum packaging machine is not allowed to be placed and impacted during the handling process, and it cannot be carried over.
10. The vacuum packaging machine must have a reliable grounding device during installation.
11. It is strictly forbidden to put your hand under the heating rod to prevent injury and immediately cut off the power in case of emergency.
12. When working, first ventilate and then energize. When the machine is shut down, first cut off the electricity and then cut off the gas.
