◆ Consider the combination of gas fields and conditions.
If the use of air space is narrow (marine, automotive), it should be vertical; if there is a long-distance change in the use of air (more than 500 meters), it should consider mobile; if the use of electricity can’t be used, it should choose diesel engine driving; if there is no running water in the use of occasions, it must choose air-cooled.
Users often have a wrong idea about air-cooled and water-cooled cooling modes. They think that water-cooled is good. Air-cooled modes account for more than 90% of small air compressors at home and abroad. This is because air-cooled is simple in design and no water source is needed in use.
There are four fatal shortcomings of water-cooled air compressor: it must have complete upper and lower water system with large investment; water-cooled cooler has short life; it is easy to freeze the cylinder in winter in the north; it will waste a lot of water in normal operation.
◆ Consider the quality of compressed air.
Generally, compressed air produced by air compressors contains a certain amount of lubricating oil and a certain amount of water. In some cases, oil and water are forbidden. At this time, attention should be paid not only to the selection of air compressors, but also to the addition of ancillary devices when necessary.
The solution is to select a non-lubricated air compressor. The air compressor cylinder is basically oil-free, and its piston rings and fillers are generally polytetrafluoroethylene. But this machine also has shortcomings, poor lubrication, high failure rate; PTFE is also a harmful substance, food, pharmaceutical industry can’t use; no lubrication air compressor can only achieve gas transmission without oil, can’t do without water. The second and commonly used method is to add the air compressor (either) to the first or second stage purification device or dryer. This device can make the air of air compressor contain neither oil nor water, and make the oil and water content in compressed air less than 5 ppm, which can meet the technological requirements.
◆ We should consider the safety of air compressor operation.
Air compressor is a kind of machine working under pressure, which is accompanied by temperature rise and pressure, and its safety should be put in the first place. The state implements a standardized "two certificates" system for the production of air compressors, i.e. air compressor production license and pressure vessel production license (gas storage tank). Therefore, when selecting air compressor products, we must strictly examine the "two certificates". Usually the quality assurance system of certified manufacturer is perfect, there will be no major quality problems, even if there are some problems, the manufacturer will be responsible for three packages.
