Oil-free air compressor has two compression modes, water lubricated oil-free air compressor and dry oil-free air compressor. We need pure oil-free compressed air. Most of them purchase equipment in these two schemes. Water-lubricated air compressors are mature enough. Shanghai Granklin Group mainly produces water-lubricated air compressors.
1, to consider the safety of oil-free air compressor operation.
Oil-free air compressor is a kind of machine with pressure operation, which is accompanied by temperature rise and pressure, and the safety of its operation should be put in the first place. The state implements the standardized "two certificates" criterion for the production of compressors, that is, the compressor production license and the pressure vessel production license (gas tank). Therefore, when purchasing compressor products, it is necessary to strictly check the "two certificates". Usually, the product quality assurance system of the certified manufacturer is perfect and will not present major quality problems. Even if there are some problems, the manufacturer will be responsible for the three guarantees.
2, to consider the compressed air quality.
Generally, the compressed air produced by the air compressor contains a certain amount of lubricating oil and a certain amount of water. In some cases, it is forbidden to oil and water. At this time, it is not only necessary to pay attention to the selection of the compressor, but also to increase the auxiliary equipment when necessary.
Solution: First, choose water-lubricated air compressor. This compressor host basically does not contain oil, and its air compressor host uses water as a lubricating substance to replace the lubricating oil of the traditional air compressor.
The gas compressed by the main engine of the water lubricated air compressor and the back-end cold dryer can remove water, so that the air compressed by the compressor contains neither oil nor water, and the oil content in the compressed air is below 5ppm, which can meet the process requirements.
3. The displacement is one of the main parameters of the water-lubricated oil-free air compressor. The gas volume of the air compressor should be matched with the required displacement, and a margin of 10%-20% should be left. If the air volume is large and the air compressor exhaust volume is small, the pneumatic tool is started, the exhaust pressure of the air compressor will be greatly reduced, and the pneumatic tool cannot be driven. Of course, it is also wrong to blindly pursue large exhaust volume. As the larger the exhaust volume, the larger the motor equipped with the compressor, not only the price is high, but also the purchase funds are wasted. In daily production and use, electricity will be wasted and energy consumption will be increased.
In the case of permanent magnet variable frequency screw air compressor which is good to use (commonly used single-stage compression screw machine), the permanent magnet variable frequency air compressor is often unfamiliar with the equipment of permanent magnet variable frequency air compressor and does not know what brand of permanent magnet variable frequency compressor to choose.
There are many types of air compressors, and they are generally subconsciously divided into oil-free screw air compressors and oil-free air compressors. This two in addition to the lubricating oil method is not the same as what is not the same? Mentioned oil-free air compressor many people's first reaction is not oil,
Minor maintenance only needs to replace the air compressor oil and oil filter, which is usually replaced after 500 hours of operation of the new machine. Major maintenance is carried out about 3000 hours of operation of the machine, and the air filter element of the air compressor, oil and gas separator core, motor grease, etc. Electric shift
A large amount of condensed water will be produced during the working process of the air compressor, which must be discharged in time in order not to affect the normal operation of the unit. There are two main ways of condensate discharge, manual discharge and automatic discharge. Manual discharge has a disadvantage. If the staff forgets to discharge, it will lead
Several advantages of oil-free air compressor, as well as the difference between oil-free air compressor and oil-free air compressor. Specifically, look at their differences: oil and no oil in the air compressor generally refer to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil machine is relatively large, and the oil content of the oil-free oil machine is 0.01ppm, so this oil content is used to distinguish the oil and no oil in the air compressor. There is also a full oil-free air compressor, it is not the use of oil lubrication, but the use of water lubrication, so the final discharge of the gas does not contain oil called full oil-free air compressor.
The main function of energy-saving variable frequency air compressor is to provide compressed air for all kinds of industrial systems. Obviously, as industrial equipment, it can only be trusted by everyone with good performance, and a good energy-saving variable frequency air compressor is also proved in actual use. It is able to adapt to all kinds of high-demand industrial operations.
Japan's oil-free air compressor and domestic manufacturers to compare how to choose a good? Foreign air compressor product development earlier than us, do not mean that the product is more competitive for a long time. Domestic air compressor has been very mature, such as Shanghai granklin group, is a professional
View detailsScrew air compressor pumping slow how to deal with, screw air compressor pumping slow power generally have the following reasons: screw air compressor pumping slow how to deal with? 1, the host problem. Check the air supply power of the equipment host, and close the valve behind the air tank
The gas supply pressure required by the glass industry is relatively small. If the conventional air compressor on the market is used, it will cause a waste of resources. The conventional pressure on the market is 0.7-1.0mpa, and the glass industry is 0.3-0.5mpa. This requires accurate selection during selection without wasting too much energy consumption. When your air pressure is 0.2 -- 0
Air compressor is an indispensable machine in production and life, and its existence provides great convenience for people's life. But so common equipment, there are still a lot of people do not know the role and use of air compressor in the end what?
