First, we ought to consider the exhaust pressure and the quantity of the exhaust.

Based on the national regular, the exhaust pressure of general purpose surroundings 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 equipment and wind machinery is definitely 0.4 Mpa, the working pressure of surroundings compressor can fully meet up with the requirements. If the atmosphere compressor utilized by the user is larger than 0.8MPa, it must be specially manufactured. The technique of forced pressurization can not be adopted to avoid accidents.

The size of the exhaust can be one of the main parameters of the air compressor. Choosing the air flow volume of the atmosphere compressor should match its exhaust volume and leave a 10% margin. If the air flow volume is huge and the air flow compressor exhaust quantity is small, when the pneumatic equipment start, the exhaust pressure of the surroundings compressor will be significantly reduced, however the pneumatic tools can not be driven. Of training course, additionally it is wrong to pursue large exhaust capacity blindly, since the bigger the exhaust capability, the larger the engine allocated by the air flow compressor, not only the higher the purchase price, but also a waste materials of purchasing funds, and the use of electricity and energy will end up being wasted.

Consider the combination of gas areas and conditions.

If the use of air space is narrow, it must be vertical; when there is a long-distance switch in the use of air (a lot more than 500 m), mobile type should be considered; if the use of electricity can not be used, diesel engine driving type should be selected; when there is simply no circulating water in the usage of occasions, air-cooled type should be selected. In the air-cooled and water-cooled cooling modes, many users have an incorrect idea that water-cooled is great, but in fact it isn’t. The air-cooled type accounts for more than 90% of the small compressors in the home and abroad. That is since the air-cooled type is easy in design no water source is necessary in use. There are four fatal shortcomings of water-cooled compressor: it will need to have a complete upper and lower water program with large expense; water-cooled cooler has brief life; it is simple to freeze the cylinder in wintertime in the north; it’ll waste a lot of water in regular operation.

Then consider the compressed air quality.

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

Lastly, it really is to expand the knowledge of reference.

1. Balance: With the solid rise of China’s economy and the continuous emancipation of the thoughts of all sorts of manufacturers, manufacturers all over the country are busy with creation work. Along the way of production, atmosphere compressors, which play an important role, are often fully loaded and operate all-weather. In the full production of factories, surroundings compressor gas production is definitely unstable, which is a very troublesome thing, often will bring incalculable losses. Therefore, whenever we purchase atmosphere compressors, the initial criterion is the stability of air flow compressors. At the moment, some high-end brands both in the home and overseas can meet this requirement. With the mature technology of adjustable frequency surroundings compressor, it can be thought to meet this requirement.

2. Gas creation: The second is gas creation. Some enterprises have very high quality of gas. For example, in the pharmaceutical industry, basically the gas they need is oil-free of charge. In this respect, it is still based on the enterprise’s very own situation. If the business has a high demand for this, then it has been a long period to purchase more China Pulley well-known devices. If the demand isn’t high, it depends on other situations. As the future development tendency of the surroundings compressor industry, the variable frequency air compressor is still very superb in gas production, since the variable frequency air compressor includes a prominent characteristic of monitoring gas production, and at the same time the gas quality created is very considerable.

3. Power consumption: This is a comparatively important place and also the focus of debate, because surroundings compressor, as a basic equipment, is generally managed all-weather, and air compressor itself is a very power-consuming equipment, the general manufacturer of air flow compressor power consumption makes up about 20-30% of the total plant power usage. If effective control, the result is very obvious. Many domestic enterprises are actually pursuing the bottom price. In fact, the bottom price is quite one-sided. For general production enterprises, the price of air compressor only makes up about 5% of the full total cost of atmosphere compressor, 9% of the maintenance and labor costs, and 86% of the total cost of energy. Therefore, considering the last expenditure, the frequency transformation air compressor should be much lower than the ordinary air flow compressor. Frequency conversion air flow compressor is only the first purchase, but invest the the electricity cost into account, you can really calculate a bill. Currently, the general energy-saving amount of frequency converter air flow compressor is very objective, and the domestic professional rate of recurrence converter air flow compressor, its power-saving price is as high as 30%, usually within a calendar year can recover the difference. Therefore, whenever choosing air flow compressor, choosing a good variable frequency atmosphere compressor is really the best answer to the issue of power consumption.
