First, vacuum packaging machines Shopping guide
Vacuum packaging machine vacuum pump is the most important parts of his will have a direct impact on the quality of vacuum packaging machine is good or bad, so buy a vacuum packaging machine vacuum pump should pay attention to the quality, generally a good vacuum-packed machine can have the following:
1.Vacuum packaging machine design in all parts of the rationality of the link, installed fine on a good level of vacuum machines are to some extent.
2. Vacuum packaging machine electrical differences, a good electrical components are not easily broken, poor electrical components is not the same.
3. Vacuum Packing Machine exterior materials used: There is now divided into paint and stainless steel, stainless steel models are also different, and now the best vacuum machine is used 304 steel.
4. Vacuum packaging machine vacuum pumps, there is some good and bad effects of the different use of the environment, different packaging, vacuum pump is good or bad will be apparent, mainly in the life of the vacuum pump and the pumping speed differences. Vacuum pump Maintenance is also a key part, does not maintain a good vacuum is very easy to bad.

Second, the maintenance of vacuum packaging machine

1,on decompression, Forklift filtering, oil mist triple piece 24 to carry out regular checks to ensure that oil mist, oil cup of oil (sewing machine oil), filter cup water.
2,working after the first powered ventilation, power shutdown after the first expire.
3, should always take apart and wash the filter impurities (usually 1-2 months, washed once, such as packaging debris-like objects should be shortened cleaning time).
4 2-3 months of continuous work should open the rear cover 30 to slide blocks of the location and switch hitting lubricating, heating rods on various connections on the activities of Department should, as the use of lubrication.
5, vacuum packaging machine should be in the temperature -10 ℃ -50 ℃, relative humidity less than 85%, ambient air, corrosive gas, no dust, no explosive hazardous environments. The same as the baler and shrink machine, the vacuum packaging machine for the three-phase 380V power supply.
6, heating section, silicone strips to keep clean, not sticky a foreign body, so as not to affect the sealing quality.
7, are strictly forbidden to hand put into a heated rod, to prevent injury, turn off the power immediately in emergency situations.
8, user-owned gas source and the inflatable working gas source, vacuum packaging machine working pressure is set to 0.3MPa, more appropriate, no special circumstances do not regulate too much.
9, vacuum packaging machine in the removal process does not MDF Door allow inclined position and impact, but not down to the ground handling.
10, vacuum packaging machine is installed must have a reliable grounding device.
11, heating rods, on the second floor under the heating film adhesive paste from the insulation, should be promptly replaced when damaged, to avoid short circuit.
12, vacuum pump for the vacuum packaging machine to ensure the normal work of vacuum pump motor does not allow reverse. Should always check the oil level, the normal oil level for the oil window 1/2-3/4 office (not more than), when there is water or oil pumps in the color black, the time should be replaced with new oil (usually one or two Labeling Machine consecutive months to replace one with a # 30 # gasoline or petrol vacuum, oil also can).
