Consider occasions and conditions
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.
