| Vacuum, the term translated from Latin vacuo, its meaning is nothing. In fact, the vacuum should be understood as a more rarefied gas of space. In the designated space, less than an atmospheric pressure of the gas state referred to as vacuum. Rarefied gas under vacuum as the vacuum level (degree ofvacuum), usually pressure indicated. Therefore, vacuum packaging is not really complete vacuum, using vacuum packaging technology for food packaging vacuum within the container is usually 600-1333Pa. So, in turn called the vacuum packaging or vacuum packaging exhaust packaging. Vacuum packaging technology originated in the 20th century, 40 years. In 1950, polyester, polyethylene plastic film [1] successfully used for vacuum packing, then, vacuum packaging has been developed rapidly. Our vacuum packaging technology in the last century, developed in the early 80s, and the vacuum inflatable packaging technology in the last century a small amount of use since the early 90s, with little promotion and packaging of supermarket development, its scope more and more widely Some will gradually replace the rigid packaging, the prospects are very promising The technology of vacuum packaging machine 1, and out of feeding method: the way forward right out of style 2, the squeezed vacuum packaging machine with a fixed instant hot box heating, energy saving 3, a special heating arrangement, the heat distribution. 4, body size, small footprint. 5, suitable for small batch production and the volume of production. Be compatible with pipeline operations, improve efficiency vacuum packaging machine. 6, used in Taiwan, Japan, South Korea imported zero with stable and reliable performance Applications of vacuum packaging machine vacuum packaging machine is plastic or aluminum foil plastic film for packaging materials, liquid, solid, powder paste food, grain, fruit, pickles, preserved fruit, chemicals, medicines, electronic components, precision instruments, metals such as vacuum packaging, vacuum packaging items to prevent oxidation, mildew, insects, decay, moisture, extending shelf-life preservation period. Especially for tea, food, medicine, shops, research institutions and other industries, with beautiful appearance, compact structure, high efficiency, easy operation. Principle of the selection of vacuum packaging machine vacuum packaging machine variety, considered in the selection of the following factors should be highlighted. a) Packing speed. For improving production efficiency considerations, the choice of dual-chamber or multi-chamber vacuum packaging machine, in order to improve the whole A production schedule. b) packaging materials need to be filled with other protective gas. Optional inflatable device with a multi-functional vacuum packaging machine. c) vacuum packaged goods requirements. Such as packaging materials need a high degree of vacuum can be preserved under the conditions, you need to select the chamber vacuum packaging machine. d) packaging materials for components to be state of the vacuum packaging machine requirements. When you purchase, packaging, solid, granular and other relatively dry and non-corrosive materials, the choice of aluminum alloy material, and packaging with the soup, salt, acid composition of the material higher, you can use stainless steel or aluminum-magnesium alloy . General use of silicone rubber ring, black rubber, a small number of low-grade products using foam rubber, silicone rubber high temperature, corrosion resistance, good sealing and long service life, poor sealing foam rubber, easy to fall off, life is short. Vacuum packaging machine Troubleshooting: In the process of using a vacuum packaging machine may encounter the following major common problems: 1. Vacuum is low 2. Noise 3. Vacuum pump injector 4. Vacuum pump oil 5. Vacuum pump fumes big 6. Without heating 7. Heating is not Stop 8. sealing uneven, not tight or sealed steel boxes steel boxes deformation adjustment 9. side of the heating, while not heating 10. vacuum pump will not turn 11. closing lid does not work, etc. 1, pump oil pollution, too little or too thin vacuum cleaning, replace the vacuum pump oil; exhaust extraction time is too short to extend the time; exhaust filter plugging exhaust filter cleaning or replacement; a leak Department, taking time off after power, check valve, fittings, valves and vacuum suction around the studio without leakage at the gasket. 2, vacuum pump coupling wear and tear replacement; exhaust filter clogging or installation location is not correct, clean or replace the exhaust filter and installed correctly; a leak at the check valve for leakage and exclusion. 3, the suction valve O-ring off the mouth of the vacuum pump disconnect and remove the exhaust nozzle, remove the compressed spring and the suction valve, gently stretching O-ring several times, re-embed the groove, then can be installed; replace the rotary vane rotary vane wear. 4, back to remove the oil return valve plug valve, cleaning (see manual); oil window let loose oil, remove the oil window, wrap Teflon tape or a thin plastic film. 5, the exhaust filter clogging or contamination of clean or replace the exhaust filter; replaced with new oil pump oil pollution; return valve plug cleaning oil return valve 6, replacement of heating the heating section shall blow; heating relay burned out (the boot that is both bright light at the same time, OMRON light yellow color), the replacement time relay; plus add hot hot blown replacement and installation firm; control heating temperature band switch is bad, repair or replacement; control the heating of the AC contactor does not reset the repair (with air blow off the foreign body) or replaced; heating replacement transformer bad 7, the heating time the relay is bad or burned, adjust the time or replace the relay and socket contacts; control the heating contactor does not reset the repair or replacement 8, the heating time and heating temperature is not adjusted to the appropriate adjustments; heating fixtures on cloth gently scrape with a fingernail attachments; pressure solenoid valve does not clean or replace the solenoid valve; airbag replacement of damaged air bag; pressure pipe breakage repair or replacement; hold the bad air cooling relay (electrical box) replacement time relay; release valve circuit breaker and take a good look; release valve stuck or burned out removed for cleaning or replacement 9, the side bags are not heated and the pressure of the heating device short-circuit (usually with short brazing sheet) to adjust the location of copper lug, or the rest pocketed layering packaging 10, the studio will not Gaiyan studio Gaiyan; motor reversal (note the not-for-ground, ground color line); Insurance-off (indicator light) replacement of the same specification Insurance 11, no power see whether the power supply; travel limit switch adjustment switch is not action picks; Insurance-off (indicator light) replacement of the same size fire insurance to the Insurance Department to find and eliminate short-circuit; motor reversal prolonged arbitrary two-phase power line exchange installation (except ground); oil viscosity is too high cleaning pump and oil change box picks the insurance repair a short circuit at How to maintain a vacuum packaging machine? 1, vacuum packaging machine should be at a temperature -10 ℃ -50 ℃, relative humidity less than 85%, non-corrosive gases in ambient air, no dust, no explosive hazardous environments. The same as strapping and shrink machine, the vacuum packaging machine for three-phase 380V power supply. 2, vacuum pump for the vacuum packaging machine to ensure the normal operation, vacuum pump motor does not allow reverse. Should always check the oil level, the normal oil 1/2-3/4 at the oil window (not over), when the vacuum pump in water or oil color black, the new oil should be replaced at this time (usually one or two consecutive months to replace one, a vacuum with a # 30 # gasoline or petrol, oil can). 3, the impurities should always take apart and wash the filter (usually 1-2 months, washed once, debris-like objects such as packaging cleaning time should be shortened.) 4, 2-3 months of continuous work should open the back cover switch 30 on the sliding parts and lubricating the collision block of the heating rod connection on the activities of the Department should be considered the use of lubrication. 5, vacuum, filtration, oil mist triple pieces 24 should always check to ensure that oil mist, oil the cup with oil (sewing machine oil), filter cup water. 6, heating section, silicone strips to keep clean and not stick a foreign body, so as not to affect the sealing quality. 7, heating rods, on the second floor under the heating plate is insulated from the effect of viscous paste, should be promptly replaced when damaged, to avoid short circuit. 8, the user-owned work and inflatable air 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 allow inclined position and impact, but can not be tipped over handling. 10, vacuum packaging machine in the installation must have a reliable grounding device. 11, is strictly prohibited under the hand into the heating rods to prevent injuries, cut off the power immediately in emergency situations. 12 hours of work after the first power ventilation, power shutdown after the first expire.
