If the venue is small (marine, vehicle), vertical type should be selected; if there are long-distance changes in the occasion (more than 500 meters), you should consider the mobile type; if you can not use the occasion to supply power, you should choose diesel engine-driven; When there is no tap water for use, air-cooled type must be selected.
In air-cooled and water-cooled cooling systems, users often have the wrong understanding and believe that water cooling is good, but it is not. The air-cooled type of small-sized carton sealing machines at home and abroad accounts for about 90% of the total. This is because the design is simple in air-cooling, and no water is needed for use.
The water-cooled sealing machine has four fatal flaws: it must have a complete water system and a large investment; the water-cooled cooler has a short life; in the north, it is also easy to freeze the cylinder; in the normal operation, a lot of water will be wasted.
To consider compressed air quality
Generally, the sealing machine produces compressed air containing a certain amount of lubricating oil, and has a certain amount of water. In some cases, it is prohibited to ban oil and water. In this case, attention must be paid not only to the selection of the sealing machine, but also to the attachment if necessary.
Solution: First, use a non-lubricated sealing machine. The sealing machine cylinder is substantially free of oil and its piston rings and packing are typically PTFE. However, this kind of machine also has disadvantages, poor lubrication, high failure rate; PTFE is also a harmful substance, food and pharmaceutical industry can not be used; non-lubricated sealing machine can only do gas without oil, can not be without water . The second and commonly used method is to add the sealing machine (regardless of the type) to a primary or secondary purification device or dryer. This device can make the sealing machine air not only contains no oil and no water, so that the amount of oil and water contained in the compressed air is below 5ppm, which can meet the technical requirements. The sealing machine makes the product more beautiful.
To consider the safety of the sealing machine operation
The sealing machine is a working machine with pressure, accompanied by temperature rise and pressure during work, and its operation safety must be placed first. Therefore, when choosing a sealing machine product, it is best to choose a regular manufacturer. Usually the regular manufacturer's product quality assurance system is perfect, there will be no big quality problems, even if there are some problems, the manufacturers will also be responsible for the three bags, you can find factory service to help you solve.
