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

Based on the national standard, the exhaust pressure of general purpose surroundings Rotary Air Compressor 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 usually 0.4 Mpa, the functioning pressure of air flow compressor can fully meet up with the requirements. If the air compressor utilized by the consumer 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 can be one of the primary parameters of the air compressor. Choosing the atmosphere volume of the air flow compressor should match its exhaust volume and leave a 10% margin. If the atmosphere volume is large and the atmosphere compressor exhaust quantity is little, when the pneumatic equipment start, the exhaust pressure of the atmosphere compressor will be greatly reduced, however the pneumatic tools can’t be driven. Of program, it is also wrong to pursue huge exhaust capacity blindly, since the bigger the exhaust capacity, the larger the electric motor allocated by the surroundings compressor, not merely the higher the price, but also a waste materials of purchasing funds, and the utilization of energy and energy will become wasted.

Consider the mixture of gas fields and conditions.

If the utilization of air space is narrow, it should be vertical; when there is a long-distance modification in the use of air (a lot more than 500 m), mobile type is highly recommended; if the use of electricity can’t be used, diesel engine traveling type should be selected; when there is simply no circulating drinking water in the use of occasions, air-cooled type should be chosen. In the air-cooled and water-cooled cooling settings, many users have an incorrect idea that water-cooled is good, but in fact it isn’t. The air-cooled type accounts for a lot more than 90% of the small compressors at 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 will need to have a complete higher and lower water system with large purchase; water-cooled cooler has brief life; it is simple to freeze the cylinder in winter in the north; it will waste a whole lot of water in normal operation.

After that consider the compressed quality of air.

Generally, compressed air produced by air compressor contains a specific quantity of lubricating oil and water. In some cases, it really is prohibited from essential oil and water. At this time, attention should be paid not merely to the selection of compressor, but also to the addition of auxiliary gadgets 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 minds of all types of manufacturers, manufacturers from coast to coast are busy with production work. Along the way of production, air compressors, which play a significant role, are often fully loaded and operate all-weather. In the full production of factories, atmosphere compressor gas production is unstable, which is an extremely troublesome thing, often will bring incalculable losses. Therefore, when we purchase atmosphere 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 necessity. With the mature technology of variable frequency air flow compressor, it can be thought to meet this requirement.

2. Gas creation: The second reason is gas creation. Some enterprises have very high quality of gas. For example, in the pharmaceutical industry, basically the gas they want is oil-free of charge. In this regard, it is still based on the enterprise’s very own situation. If the business includes a high demand for this, then it has been a long time to purchase more well-known devices. If the demand is not high, it depends upon other conditions. As the future development pattern of the atmosphere compressor industry, the variable frequency air compressor is still very superb in gas production, because the variable frequency air compressor has a prominent characteristic of monitoring gas creation, and at exactly the same time the gas quality created is very considerable.

3. Power consumption: That is a relatively important place as well as the focus of conversation, 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 atmosphere compressor power consumption accounts for 20-30% of the full total plant power usage. If effective control, the result is very apparent. Many domestic enterprises are actually pursuing the bottom price. In fact, the bottom price is rather one-sided. For general creation enterprises, the price of surroundings compressor only accounts for 5% of the total cost of surroundings 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 must be much lower compared to the ordinary air flow compressor. Frequency conversion air flow compressor is only the first expense, but if you take the electricity cost into account, you can really calculate a bill. Today, the overall energy-saving amount of frequency converter air flow compressor is quite objective, and the domestic professional rate of recurrence converter air flow 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 air flow compressor is really the very best remedy to the problem of power consumption.
