Buying a vacuum packaging machine is like buying other packaging equipment. It requires some skill. The author is a vacuum packaging machine salesman. Now I have summarized some experiences as follows:
First, the vacuum packaging machine vacuum pump is the main component of the vacuum packaging machine, his quality directly affects the quality of the vacuum packaging machine, so pay attention to the quality of the vacuum pump when purchasing the vacuum packaging machine, generally come Say a good vacuum packaging machine can have the following:
1. The material used for the vacuum packaging machine: There are different types of paint and stainless steel, and the type of stainless steel is different. Now the machine used on the vacuum machine is 304 steel.
2. Differences in vacuum packaging machine electrical appliances, good electrical components are not easy to break, poor electrical components are not the same.
3. The rationality of the link design of each part of the vacuum packaging machine, the fineness of the installation has a certain impact on a good vacuum machine.
4. The vacuum pump vacuum pump has a certain impact on the quality of the vacuum pump, the different use environment, the different packaging materials, the quality of the vacuum pump will be revealed, mainly in the life of the vacuum pump and the difference in pumping rate. Vacuum pump Maintenance is also the main key link, and good vacuum pumps are not easy to maintain.
Second, vacuum packaging machine maintenance 1, vacuum packaging machine should be in the temperature -10 ° C -50 ° C, relative humidity is not more than 85%, no corrosive gas in the surrounding air, no dust, no explosive atmosphere. 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 consecutive work) 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. Check the decompression, filtration and oil mist triplets 24 frequently to ensure oil mist (sewing machine oil) in the oil mist and oil cup, and no water in the filter cup.
6. The heating strip and the silicone strip should be kept clean and free from foreign matter, so as not to affect the quality of the seal.
7. On the heating rod, the two-layer adhesive under the heating sheet will be insulated, and should be replaced in time when there is damage, so as to avoid short circuit.
8. The user has self-prepared working air source and inflatable gas source. The working pressure of the vacuum packaging machine has been set to 0.3 MPa, which is more suitable. Do not adjust too much without special circumstances.
9. Vacuum packaging equipment 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 when it is installed.
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.
Fresh White Radish
The white radish is known as rhizome vegetable, cruciferous radish. Planting has a history of thousands of years and is widely used in the fields of diet and traditional Chinese medicine. The Rugao County Chronicle compiled in the Gengwu year of Qianlong of the Qing Dynasty (1750 AD) contains: "radish, a radish, has two kinds of red and white. It can be planted in four seasons. Only the last is good at the beginning. It can be eaten by breaking armour. Those who grow Sandy soil are sweet and crisp, and those who grow barren soil are firm and spicy."
It is white in color, belongs to gold, enters the lung, is sweet, smooth and pungent in nature, belongs to the lung and spleen meridian, and has the effects of lowering Qi, eliminating food, removing diseases, moistening the lung, detoxifying and generating fluid, diuresis and defecation. It is mainly used for lung flaccidity, lung heat, constipation, hematemesis, flatulence, food stagnation, dyspepsia, phlegm, obstructed defecation, alcoholism, etc.
