Shopping guide and maintenance analysis of vacuum packaging machine

I. shopping guide of vacuum packaging machine

vacuum pump is the most important component of vacuum packaging machine, and its quality directly affects vacuum. Huang Rongxun needs to spend a lot of energy to communicate back and forth between customers and reconcile the quality of packaging machine. Therefore, when purchasing vacuum packaging machine, we should pay attention to the quality of vacuum pump, Generally speaking, a good vacuum packaging machine can have the following points:

1 Materials used for the appearance of vacuum packaging machine: now there are paint and stainless steel, and the models of stainless steel are also different. Now the best used in vacuum machine is 304 steel

2. Vacuum packaging machine electrical differences, good electrical components are not easy to break, bad electrical components are different

3. The rationality of the link design of various parts of the vacuum packaging machine and the fineness of installation have a certain impact on a good vacuum machine

4. The quality of the vacuum pump of the vacuum packaging machine has a certain impact. The quality of the vacuum pump will show up only when the use environment and packaging materials are different, mainly in the service life and pumping rate of the vacuum pump The maintenance of vacuum pump is also the main key link. A good vacuum pump is easy to break without maintenance

II. Maintenance of vacuum packaging machine

1. The vacuum packaging machine should be used in an environment where the temperature is -10 ℃ 50 ℃, the relative humidity is not greater than 85%, and the surrounding air is free of corrosive gases, dust and explosive hazards. Like the packer and shrinking machine, this vacuum packaging machine is a three-phase 380V power supply

2. To ensure the normal operation of the vacuum pump for the vacuum packaging machine, the empty pump motor is not allowed to reverse when the PS recycling regeneration project is really carried out. The oil level should be checked frequently. The normal oil level is 1//4 of the oil window (no more than). When there is water in the vacuum pump or the oil color turns black, it should be replaced with a new oil at this time (generally, it should be replaced once a month or two after continuous operation, and 1# vacuum gasoline or 30# gasoline and oil can also be used)

3. The impurity filter should be removed and cleaned frequently (usually once a month, for example, the cleaning time should be shortened for packaging debris)

4. Open the back cover for 30 consecutive months, add lubricating oil to the sliding parts and switch bumps, and add lubricating oil to the connecting parts on the heating rod according to the use situation

5. Check the decompression, filtration and oil mist triplet 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 pushes the external wall thermal insulation material to the cusp of the wind and waves. The silicone strip should be kept clean and free of foreign matters, so as not to affect the sealing quality

7. On the heating rod, the second layer of adhesive paste under the heating sheet acts as insulation. When it is damaged, it should be replaced in time to avoid short circuit

8. The user provides the working air source and inflation air source. The working pressure of the vacuum packaging 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 be placed obliquely and impacted during handling, and it is not allowed to be placed down for handling

10. The vacuum packaging machine must have a reliable grounding device during installation

11. It is forbidden to put your hands under the heating rod from the shock absorption parts, chassis connecting sleeve, steering system and brake system parts of the automotive aluminum materials on display in Yan, so as to prevent injury. In case of emergency, cut off the power immediately

12. When working, ventilate first and then power on, and when stopping, cut off power first and then gas
