First, we should consider the exhaust pressure and the volume of the exhaust.

According to the national standard, 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). As the style functioning pressure of pneumatic tools and wind machinery is definitely 0.4 Mpa, the functioning pressure of air compressor can fully meet up with the requirements. If the air compressor utilized by the user is larger than 0.8MPa, it must be specially manufactured. The technique of forced pressurization can’t be adopted to avoid accidents.

The size of the exhaust is also one of the main parameters of the air compressor. Choosing the air volume of the surroundings compressor should match its exhaust quantity and leave a 10% margin. If the atmosphere volume is large and the atmosphere compressor exhaust volume is small, when the pneumatic tools start, the exhaust pressure of the air flow compressor will be greatly reduced, however the pneumatic tools can not be driven. Of course, it is also wrong to pursue large exhaust capacity blindly, because the larger the exhaust capacity, the larger the engine allocated by the air compressor, not only the higher the purchase price, but also a waste materials of purchasing funds, and the utilization of power and energy will be wasted.

Consider the mixture of gas fields and conditions.

If the use of air space is narrow, it must be vertical; if there is a long-distance change in the use of air (more than 500 m), mobile type should be considered; if the utilization of electricity can’t be used, diesel engine generating type ought to be selected; when there is simply no circulating drinking water in the usage of occasions, air-cooled type ought to be selected. In the air-cooled and water-cooled cooling settings, many users have a wrong proven fact that water-cooled is great, but in fact it isn’t. The air-cooled type accounts for a lot more than 90% of the tiny compressors in the home and abroad. That is because the air-cooled type is simple in design and no water source is needed used. There are four fatal shortcomings of water-cooled compressor: it must have a complete upper and lower water system with large expenditure; water-cooled cooler has short life; it is easy to freeze the cylinder in winter season in the north; it will waste a lot of water in normal operation.

After that consider the compressed air quality.

Generally, compressed air made by air compressor contains a particular amount of lubricating oil and water. In some cases, it Motorbase really is prohibited from oil and water. At this time, attention ought to be paid not merely to the selection of compressor, but also to the addition of auxiliary products when necessary.

Lastly, it is to expand the knowledge 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 all over the country are busy with production work. Along the way of production, air flow compressors, which play an essential role, are often fully loaded and operate all-weather. In the entire production of factories, atmosphere compressor gas production is unstable, which is an extremely troublesome thing, often provides incalculable losses. Therefore, whenever we purchase surroundings compressors, the initial criterion is the stability of atmosphere compressors. At present, some high-end brands both in the home and overseas can meet this requirement. With the mature technology of variable frequency surroundings compressor, it could be thought to meet this requirement.

2. Gas creation: The second is gas production. Some enterprises possess very good quality of gas. For instance, in the pharmaceutical sector, basically the gas they need is oil-free of charge. In this regard, it is still based on the enterprise’s personal situation. If the enterprise has a high demand for this, then it’s been a long period to buy more well-known devices. If the demand is not high, it depends on other circumstances. As the near future development craze of the atmosphere compressor industry, the variable frequency air compressor continues to be very exceptional in gas production, since the variable frequency surroundings compressor includes a prominent characteristic of monitoring gas production, and at exactly the same time the gas quality created is very considerable.

3. Power consumption: This is a relatively important place as well as the focus of discussion, because surroundings compressor, as a basic equipment, is generally managed all-weather, and air compressor itself is an extremely power-consuming equipment, the overall manufacturer of atmosphere compressor power consumption accounts for 20-30% of the full total plant power consumption. If effective control, the result is very obvious. Many domestic enterprises are now pursuing the base price. In fact, the bottom price is quite one-sided. For general creation enterprises, the purchase price of air compressor only accounts for 5% of the full total cost of atmosphere compressor, 9% of the maintenance and labor costs, and 86% of the total cost of electricity. Therefore, considering the last expenditure, the frequency transformation air compressor must be much lower compared to the ordinary air flow compressor. Frequency conversion surroundings compressor is the first expenditure, but invest the the electricity price into account, you really can calculate a bill. Currently, the overall energy-saving amount of frequency converter atmosphere compressor is quite objective, and the domestic professional regularity converter surroundings compressor, its power-saving price is really as high as 30%, usually within a year can recover the difference. Therefore, whenever choosing air flow compressor, choosing a good variable frequency surroundings compressor is really the very best solution to the issue of power consumption.
