First, we have to consider the exhaust pressure and the volume of the exhaust.
Based on the national regular, the exhaust pressure of general purpose air flow compressor is 0.7 MPa (7 atmospheric pressure) and the old standard is 0.8 MPa (8 atmospheric pressure). Because the design working pressure of pneumatic tools and wind machinery is normally 0.4 Mpa, the functioning pressure of surroundings compressor can fully meet up with the requirements. If the surroundings compressor utilized by the user is larger than 0.8MPa, it should be specially manufactured. The method of forced pressurization can’t be adopted in order to avoid accidents.
How big is the exhaust is also one of the main parameters of the air compressor. Choosing the air volume of the air flow compressor should match its own exhaust volume and leave a 10% margin. If the air flow volume is huge and the air compressor exhaust volume is small, when the pneumatic equipment start, the exhaust pressure of the atmosphere compressor will be significantly reduced, but the pneumatic tools can’t be driven. Of course, additionally it is wrong to pursue large exhaust capacity blindly, since the larger the exhaust capacity, the larger the motor allocated by the air flow compressor, not only the higher the purchase price, but also a waste of buying funds, and the utilization of energy and energy will end up being wasted.
Consider the China Air Compressors combination of gas fields and conditions.
If the use of air space is narrow, it must be vertical; when there is a long-distance change in the usage of air (a lot more than 500 m), mobile type is highly recommended; if the use of electricity can’t be utilized, diesel engine generating type ought to be selected; if there is simply no circulating drinking water in the use of occasions, air-cooled type ought to be chosen. In the air-cooled and water-cooled cooling modes, many users have a wrong proven fact that water-cooled is good, but in fact it is not. The air-cooled type accounts for a lot more than 90% of the tiny compressors at home and abroad. That is because the air-cooled type is simple in design no water source is needed in use. There are four fatal shortcomings of water-cooled compressor: it will need to have a complete top and lower water system with large purchase; water-cooled cooler has brief life; it is easy to freeze the cylinder in winter season in the north; it will waste a lot of water in regular operation.
After that consider the compressed quality of air.
Generally, compressed air made by air compressor contains a specific quantity of lubricating oil and water. In some instances, it is prohibited from essential oil and water. At this time, attention ought to be paid not only to selecting compressor, but also to the addition of auxiliary products when necessary.
Lastly, it really is to expand the data of reference.
1. Balance: With the solid rise of China’s overall economy and the constant emancipation of the minds of all sorts of manufacturers, manufacturers from coast to coast are busy with creation work. In the process of production, air flow compressors, which play an essential role, are often completely loaded and operate all-weather. In the entire production of factories, atmosphere compressor gas production is certainly unstable, which is a very troublesome thing, often will bring incalculable losses. Therefore, when we purchase atmosphere compressors, the 1st criterion may be the stability of atmosphere compressors. At the moment, some high-end brands both at home and abroad can meet this necessity. With the mature technology of adjustable frequency air flow compressor, it can be thought to meet this requirement.
2. Gas creation: The second reason is gas production. Some enterprises possess very high quality of gas. For example, in the pharmaceutical industry, basically the gas they need is oil-free. In this respect, it is still predicated on the enterprise’s personal situation. If the business includes a high demand because of this, then it’s been a long time to purchase more well-known devices. If the demand is not high, it depends on other situations. As the future development development of the air flow compressor industry, the adjustable frequency air compressor continues to be very superb in gas production, since the variable frequency air flow compressor includes a prominent characteristic of monitoring gas production, and at the same time the gas quality produced is very considerable.
3. Power consumption: This is a relatively important place and also the focus of dialogue, because atmosphere compressor, as a basic equipment, is generally operated all-weather, and air flow compressor itself is an extremely power-consuming equipment, the general manufacturer of surroundings compressor power consumption accounts for 20-30% of the full total plant power consumption. If effective control, the effect is very apparent. Many domestic enterprises are now pursuing the bottom price. In fact, underneath price is quite one-sided. For general creation enterprises, the price of atmosphere compressor only makes up about 5% of the full total cost of air flow compressor, 9% of the maintenance and labor costs, and 86% of the full total cost of electric power. Therefore, considering the last expenditure, the frequency transformation air compressor should be much lower compared to the ordinary air compressor. Frequency conversion surroundings compressor is only the first investment, but if you take the electricity price into account, you can really calculate a bill. Currently, the overall energy-saving amount of frequency converter air flow compressor is quite objective, and the domestic professional regularity converter atmosphere compressor, its power-saving rate is really as high as 30%, usually within a 12 months can recover the difference. Therefore, whenever choosing surroundings compressor, choosing an excellent variable frequency surroundings compressor is really the very best option to the problem of power consumption.
